I was on Offical leaked Taiwan version of ICS, then i decided to move to XXLPY version of ICS. I went to CMW to full wipe data, but for some reason, my note froze during data wiping...
I have waited long enough, but it was froze. With no choice, I removed the battery then tried to boot, but it was stuck on the first screen.
From then on, I have tried to recover my note using various Offical ROMs, the taiwan leak, German leak and even old GB ROMs, but I am stuck at Factoryfs...
I am pretty sure Ive tried everything, add PIT and not add PIT, Kernel, etc...
For some reason, Kernel can be flashed just fine, but when it comes to ROMs, it stucks at this screen.

Thank you Forest1971 for this great guide
And the bricks resumes......
Send it back to samsung service center. Hope you have warranty.
Zapped through server hops to XDA forums
WTF!!!! who told you to wipe on LPF??? who told you not to read the PSA??
One more. We could actually make a movie about it now. :/
My commiserations man. Take it to Samsung.

But I can't help saying that you are actually very brave. You could read about how to flash all this (assuming you did it yourself) but couldn't read about the possible risks. Every forum these days is about "bricked due to wipe" or "avoid wiping to avoid brick". I am not trying to give you a lecture or something and I really hope Samsung fixes it for free but please, next time search before you do anything potentially dangerous.

There has been confirmation that In many cases it is the faulty system partitions (caused by wipe using the buggy ICS stock kernel or other reasons). In that case re-partition workaround will help revive your brick phone. The first one who has applied the method successfully is "Drnull" for another similar device (epic4g).
So for those who would like to use this solution follow the guide below which I developed based on the hints from Drnull and a re-partition guide for Kindle Fire by Eldarerathis and Soundwire.
Credits and thanks to them.
Big thanks to: Prabhu1980, Matiasg85, Uggies, Bodivas, As i9000, Alekhkhanna, Travis82 and others who have provided precious tools, troubleshoot solutions, advice and support for making this guide more complete and easy to use! Also Special thanks to Lyriquidperfection for his great PIT Magic and Hg42 for his custom PIT method!
------------------
I. Case Classification and solution when there is no recovery mode:
1. Case A. If you can enter recovery: then use scanning tool to find where the damage is. Should use hg42 scanners or use the procedures described in the manual method below (Go until steps 4 to find the answers). The scanning can guide you to find the most suitable strategy for re-partition. After scanning you can use the most suitable custom pit files from the set of custom pit files in hg42's thread or use the method in this guide or a combination of both in an intuitive way to revive your brick Note. .
2. Case B. If you only have download mod, no recovery: if you flash using odin and it gets stuck at factoryfs or datafs repeatedly and you have made wipe/factory reset using ICS stock kernel, then you certainly have emmc brick. You can try to flash some kernel attached in this guide to see if can enter recovery. IF yes, then go back to Case A. If not you can use a blind method using the custom pit files below. Try one by one. The one from 2.0 should work for you. If not then from 2.1 to 2.5, one of those should work.
2.0. Custom pit that works for most cases of emmc brick
2.1. Custom pit option 1
2.2. Custom pit option 2
2.3. Custom pit option 3
2.4. Custom pit option 4
2.5. Custom pit option 5
-----------------------------------
II. Manual re-partition
Notes for using Manual repartition:
1. For those who can get SS warranty service to fix it for free then you should go there, and do not need to try repartition.
2. know how to run command prompt (MS-DOS) from window.
3. Partitions can be delete and recreate like in a computer hdd and it is reversible: you can do and redo again and again and can also go back to original scheme by flashing original PIT file.
4. If you like to recover data from your internal sdcard (photos, music, books...) you should look at Item 9 near the end of the guide.
5. And do not try to hold me responsible if you mess things up further than your current state in your phone.
1. The tools:
- Download the screen shot of the Note’s partitions for your reference information
- Install USB driver: You should be able to have adb driver for Note. If not, then download Note usb driver from here.
- Prepare adb folder: download adb folder from Here and extract adb folder to c: driver of your computer, you will have the tools folder which has adb.exe in it. You should now have adb working for your Note.
- Install custom recovery so that you can get into recovery and connect adb.
+ if you have installed GB rom (as part of the unbrick process) then download and install the attached 4pda_kernel.tar from Here.
It will raise flash counter but you can reset later using Triangleaway by Chainfire.
+ If you were ICS rom: then download and flash Speemod kernel for ICS Here., using odin.
+ If you were on JB rom then download and flash Speedmod kernel for JB from Here.
2. Set up the tools:
- after flashing one of the suitable kernel from above you should now be able to enter recovery.
- Then restart the phone to recovery (Using three buttons).
- Then connect to computer using usb cable.
3. Then run cmd from your computer and cd (change directory) to the folder that has adb.exe in your computer.
Then run,
Code:
adb devices
it should give you some number then it means your device is connect in adb
then:
Code:
adb shell
it should give you the sign like this: ~ #
-------
Note: In case adb shell it only gives this sign $ (after you have installed the 4pda_kernel) then it showed there is a mismatch of that kernel with the rom that is sitting on your (semi-brick) Note and it does not give full root. In that case you should download and install this CM9 based safe kernel from this links which should help you to get full adb root access with this sign ~ #. It is a zip file and need to be install from CWM (not odin) by copy it to external sdcard or internal sdcard (by mount usb storage to PC or adb push.
-------
Then run (noted that umount is without N):
Code:
~ # umount /cache
~ # umount /system
~ # umount /data
If one of those "umount /" commands return "invalid argument" just ignore it and continue with next steps.
This is to unmount cache, systemfs and datafs partitions.
Note: it is easier to copy and paste (right click mouse) the code to CMD windown to save time and avoid typing error.
Then run the parted.
Code:
~ # parted /dev/block/mmcblk0
if it aska you to fix something just choose yes. It should give you bellow:
parted /dev/block/mmcblk0
GNU Parted 1.8.8.1.179-aef3
Using /dev/block/mmcblk0
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted)
Then run:
Code:
(parted) print
It will give you a picture of your Note’s partitions as in the screen shots I have attached. (text version is below):

12 15.2GB 15.8GB 537MB ext4 HIDDEN
--------------------
4. Scanning for Partition errors:
4.1. Use DD:
Do to a thorough scan of partitions (block damage) you can use DD command below one by one (it only read partition block by block and no write, so it is totally safe).
Damage is mostly found in partition 7, 9, 10, 11. You can use dd to check other partition from 1 to 6 as well.
Code:
(parted) quit
~ # dd if=/dev/block/mmcblk0p7 of=/dev/null
~ # dd if=/dev/block/mmcblk0p9 of=/dev/null
~ # dd if=/dev/block/mmcblk0p10 of=/dev/null
~ # dd if=/dev/block/mmcblk0p11 of=/dev/null
Scan partition 7 and 9 will be quick (less than a minute) partition 10 take about 3 minutes and 11 about 5-7 minutes.
- If it return in and outs and partition size then they are fine (no faulty blocks)
- If it freezes (or run too long more than 10 minutes), or return something like "read/write I/O error" then it means you have some damage in that respective partition and read command failed. In this case should restart CMD/adb and run the test again for the partition that give I/O error to make sure the error is permanent and result of test is reliable.
4.2. There is also anther scan tool to double check if there are partitions faults: that is e2fsck. It comes with 4_pda and CM9 kernel given. The added benefit is that it can also repair minor memory block damage.
This tool can only be used for ext4 partition (7, 9,10) and it need to be used after "umount /cache"... steps in point 3. It is suggested that before attempting with re-partition you should first try to use this tool to scan and fix the damaged block. The command is below:
Code:
~ # e2fsck -f -c –y /dev/block/mmcblk0p7
~ # e2fsck -f -c –y /dev/block/mmcblk0p9
~ # e2fsck -f -c –y /dev/block/mmcblk0p10
The results of e2fsck scanning can be as below:
- If there is no faulty block e2fsck will report: "no bad block found". then good!
- If it freezes then it has encountered emmc bug damaged and cannot fix: In this case will definitely need re-partition.
- If it report encountered some damaged block and has fixed the damage: In this case you can try to go back to install rom. If it work, that is great. If still get stuck as before then you will need to do re-partition.
Guide for the most suitable re-partition scheme after scanning partitions (read carefully for the best result):
1. In case you do not find bad blocks in the above 4 partitions, the problem is certainly not related to partitions fault. Then you should explore other unbrick methods, using Heimdall to flash instead of odin for example.
2. In case there are fault in both partition 9 and 10 then follow steps in point from 5.1 to 5.3 below. applying this scheme of re-partition should work in most cases!.
3. In case there are faulty in partition 9 only, then can follow steps in point 7 to save some more space.
4. In case there are faulty in partition 10 only, then can follow steps in point 7 to save some more space.
5. In case there are faulty blocks in Cache partition, then follow point 5.4
6. In case there are faulty in partition 11: go to point 8 .
---------------------
5. Re-partition workaround for case of faulty in partitions 9 and 10::
5.1 remove partitions to get rid of the faulty ones and make space available for new ones:
Code:
~ # parted /dev/block/mmcblk0
(parted) print
(parted) rm 9
(parted) rm 10
(parted) rm 11
That will remove three partitions factoryfs (9), datafs (10) and UMS (11) so as to make rooms for new partitions
5.2. To create three new partitions from the good area:
Code:
(parted) mkpart primary 3322.881536 4216.268288
(parted) mkpart primary 4217 6364
(parted) mkpartfs primary fat32 6364 15200
(parted) name 9 FACTORYFS
(parted) name 10 DATAFS
(parted) name 11 UMS
Notes: You can also use custom pit provided in 2.0 to re-partition in this case.
-------------
5.3. Convert format for 9 and 10: The above steps have created three new partitions. However, for 9 and 10 the format is ext2 and now need to be converted to ext4.
The easiest way is to go back to CWM in your phone. Then, go into mounts and storage menu and choose format /system and format /data. It will convert file system of partition 9 and 10 to ext4 automatically for you.
If the above steps are successful then check:
Code:
~ # parted /dev/block/mmcblk0
(parted) print
Note: after printed partition and they look fine, then should check again the partition using dd command to scan partitions 9, 10, 11 as in the step 4 to make sure that newly created partition are fault-free. If they continue to report faulty block then you will need to do re-partition again and create new partitions in the new range (by changing start and end number of partitions).
------------
Dealing with Cache partition:
5.4. It is very, very unlikely that Cache is also faulty but in case there is you can follow steps below to deal with it.
First should remove and recreate with same size and location:
Code:
(parted) rm 7
Then recreate it:
Code:
(parted) mkpartfs primary ext2 54.5 264
(parted) name 7 CACHE
Then you can go into CWM and format /cache, it will convert file system to ext4.
In case parted give I/O error then you can try to reduce the size of cache to 128MB, choose the start and end number somewhere in the space from 54.5MB to 264MB.
6. Suggestions for rom installations:
It is recommend to use a custom GB rom (Darky GB, CheckRom GB, and Rocket GB...)they are old but very good roms. Dowload links and instructions for installation can be found in this link. Custom ICS roms (such as Rocket ICS, CleaNote ICS...) are also good. They can be found from the same link for GB rom provided or from the Note development sections. Using CM9 ICS such as Nightlies is recommended since it is safe and very lightweight (less than 140 MB) so it is quick to download.
Note: Flash custom rom by CWM (load rom.zip from computer to internal or external sdcard and flash) seem to be a better way than using odin and is recommended but you can try both.
7. Guide for some cases of only one partition have faulty blocks:
7.1. In case you scan partition and identify that there are damage only in partition 9 (factoryfs) then you can remove 9, 10, and 11 and then start making partition from 1174 MB:
Code:
(parted) rm 9
(parted) rm 10
(parted) rm 11
(parted) mkpart primary 1174.405120 2067.791872
(parted) mkpart primary 2068 4215
(parted) mkpartfs primary fat32 4215 15200
(parted) name 9 FACTORYFS
(parted) name 10 DATAFS
(parted) name 11 UMS
Then go into CWM to format system and data. Then you can install rom.
7.2. In case you identify that there is faulty blocks in partition 10 only (datafs) then you can remove 10 and 11 only (leave 9 alone) and start making partition 10 from 3322 mb:
Code:
(parted) rm 10
(parted) rm 11
(parted) mkpart primary 3322 5469
(parted) mkpartfs primary fat32 5469 15200
(parted) name 10 DATAFS
(parted) name 11 UMS
Then go into CWM and format data. and you can install rom.
It is also known that the hidden partition (partition 12) is not needed for normal use and install of roms. So you can delete it and enlarge the UMS partition (to 15800mb) and you will have a larger sdcard to use.
It is also noted that the size of datafs partition does not need to be exact 2147 mb so you can create it with the size of 2000 mb or smaller or bigger as you wish.
Still the size of factoryfs partition has to be correct so that odin will accept it when flash.
8. In the case of damage in partition 11 (UMS) this often also go with damage in partition 9 and 10. In this case I have worked out 5 options of partition scheme. You need to try from one to 5. One of those should work for you.
You can also use one of the custom Pit files provided at 2.1 to 2.5 above.
Option 1:
Code:
~ # parted /dev/block/mmcblk0
(parted) print
(parted) rm 9
(parted) rm 10
(parted) rm 11
(parted) mkpart primary 4608 5501.386752
(parted) mkpart primary 5501.386752 7648.8704
(parted) mkpartfs primary fat32 7648.8704 15200
(parted) name 9 FACTORYFS
(parted) name 10 DATAFS
(parted) name 11 UMS
After done, reboot into recovery format system, format data. Then you can proceed with install stock or custom rom.
If it get errors when create partition or CWM get stuck during format then you need to try the next option of partition scheme as below.
Option 2:
Code:
(parted) mkpart primary 6400 7293.386752
(parted) mkpart primary 7293.386752 9440.8704
(parted) mkpartfs primary fat32 9440.8704 15200
Option 3:
Code:
(parted) mkpart primary 7936 8829.386752
(parted) mkpart primary 8829.386752 10976.8704
(parted) mkpartfs primary fat32 10976.8704 15200
Option 4:
Code:
(parted) mkpart primary 9216 10109.386752
(parted) mkpart primary 10109.386752 12256.8704
(parted) mkpartfs primary fat32 12256.8704 15200
Option 5:
Code:
(parted) mkpart primary 11,008 11901.386752
(parted) mkpart primary 11901.386752 14048.8704
(parted) mkpartfs primary fat32 14048.8704 15200
9. Notes on recovering files from brick phone: For recovering data from internal sdcard, there are few ways below:
- You can try to install aroma file manager under CWM recovery using file from here. It works under recovery environment and allow you to copy files from internal sdcard to external sdcard.
- If that does not work, you can follow the guide until step 4, then in step 5 remove only partition 9 and 10 and leave partition 11 alone. Then try to create a full size partition 9 (factoryfs) with about 800MB and a very small size (100mb) partition 10 (datafs) and fit these two partitions within the remaining good area in the range from 281mb to 3322mb. Then you can install a custom rom and get it working to copy files to your PC. After that you can remove partition 11 to make full size partition 9 and 10 with steps as in the guide.
- Also you can adb shell, then list directory and files in internal sdcard (~ # ls /sdcard ...etc) and then adb pull files from internal sdcard to your PC one by one.
If you like to know more about using parted, go to the documentation page here:
http://www.gnu.org/software/parted/manual/html_mono/parted.html
Update of progress: As rough figures, more than 100 users have reported successfully revised their Notes after fixing partitions problems using either manual/adb methods or custom PIT file method from Hg42 or combined both. Re-partition have revised many super-bricks Notes! .
If you can revive your Note please share your success with us so that we can share your good feeling !
And press thanks if you find this guide useful. Thanks.

wait if you can still flash a kernel then flash a GB cf root kernel then boot into CWM recovery and try to flash a nandroid restore (you have one right) ? if you don't have one then just flash any safe ROM (GB ,CM9) from CWM.
I had the same problem when LPY first hit the scene (first day ,even before it was deemed dangerous) ,and also bricked my note but could enter download and recovery just fine (only couldn't boot or flash anything else) I kept rebooting and trying to flash again again till it worked after some dozen reboots .
hopefully you can do the same.
And what do if you can't get into recovery, or CWM?
Just first boot screen stuck, or Download mode, but factoryfs stuck also?

Yeah I am stuck at the first screen too..
When I unzipped AbyssNote kernel 4.2 Final CW Touch Custom Logo, it was zlmage, not .tar file extension. Tried putting .tar at the end, still no luck.
I also tried CF-ROOT 5.3V, it was successfully flashed but again I was stuck at the first screen with yellow triangle at the bottom.
Am I trying out wrong kernels?
EDIT: I managed to find .tar file of Abyss kernel and flashing was successful, still cannot get into recovery ... seems pretty hopeless now

Go to the nearest service center.
Summary: in many cases this allows to revive (not really repair!) your N7000 (and some other samsung devices) after an emmc brick and should be relatively easy to follow. The method uses PIT files.
Note: This thread is rather old now (2012).
Please note that the emmc brick bug should be triggered only by a combination of a few conditions:
an old samsung ics kernel (from Ice Cream Sandwich versions 4.0–4.0.4, see wikipedia)
wiping or formatting by custom software, usually an old cwm of that time (especially an often used file called CWM.ZIP)
most important: an older emmc chip (or firmware).
All affected devices should be covered by the thread, some got patched PIT files, some could not be supported (see below).
Some insights here (as part of this thread)
after the problem had been analyzed by the community and Samsung, all those parts got fixed to prevent the problem for the future.
In case only one of the conditions is not true, the brick should not happen.
So if you have more current hardware (somewhat newer than note1) or current software (newer than ics), the bug will not happen.
So, as an example, S3 or Note 3 should be safe because both hardware and software are fixed.
Especially, all current roms or recoveries should be safe.
If you have a brick nowadays, it's very very unlikely it's an emmc brick. Instead you probably have some other problem.
So in most cases, don't look here, unless you are using rather old devices and rather old software.

It's sad the following has to be said in such big letters, but there are still people not reading anything and therefore failing seriously:
Please, please, please:
Read this multiple times and try to understand all aspects before using anything of this thread.
If you have questions, read it again!
If you have questions, read it again!
...
If you have questions, read it again!
If you have questions, read it again!
If you don't know exactly what you are doing, you may HARM your device seriously or even DAMAGE it for all times (e.g. meaning motherboard has to be changed with >150EUR).
If you are a noob, then please ask someone with more knowledge to assist you, but ignore those blowhards/bigmouths which will probably do more harm to your phone than you would.
If you have questions, read first post again and again and also read the whole thread!
Most questions are asked several in this thread and are already answered in this first post. Others are answered later in the thread. You should also use the search function before asking something a second time.
Please don't waste my time with superfluous questions already answered in the thread only because you are too lazy to search for it!
It took much much time to write this down and describe most aspects. So, please take a similar amount of YOUR time to read it carefully.
Certainly, my descriptions will not be perfect, so if you are SURE your question is NOT answered HERE, then you are welcome to ask in the thread. But don't expect a quick answer. I am usually very busy with other things and I am doing this only to help other people. I definitely don't generate any profit from this...
Please don't quote this post (in it's entirety), because it's very long and will disturbe all other readers. Instead post without a quote or extract some of the text you are referring to. I think this should be common sense...
You can find the former first post of this thread at post #9...I switched it with this continuously updated post, which I hope is more understandable for the users of this method.
-------------------- manual method and tools for using adb
I think forest1971's thread is better for the description of and questions about the manual method which I used first to revive my own phone. Looks like we developed the same thing at the same time. I started this thread before I read his (I also wasn't an active user of xda before).
Along the way our threads started to be companions to each other.
forest1971's thread has some useful tools for using in adb. Some of these will be useful for procedures described here.
But please read on, because I think the PIT file method is easier for most users with kind of standard emmc bricks.
It's less error prone, because you don't have to calculate the numbers yourself (my pit generator script did it already).
However, the manual method can do more, especially if you have special cases.
-------------------- find begin and end of bricked area
You can do this with my emmc partition scanner, which is flashed via recovery (this doesn't really flash, it only uses the scripting of the updater mechanism of the recovery, also called edify script).
You should write down two numbers:
* where emmc_find_brick_start.zip freezes -> BRICK_START
* where emmc_find_brick_end.zip freezes -> BRICK_END
I have reports, that the stock recovery doesn't show the output of the scanners, so you should probably install a custom recovery first (see forrest1971 's thread).
-------------------- patched pit files
I finally hacked a perl script, which generates a set of PIT files for me.
But because I cannot test the PITs on my phone (because I need it):
==> NO GUARANTY <==
Say you have a situation like this:
Code:
before: ...-|-FAC?OR??S-|??ATAFS-|-UMS------------------------------------|...
^ ^
| |
BRICK_START BRICK_END
(? = bad blocks)
The repartitioning should leave a hole in the partition table around the bricked area.
Therefore the bricked area will lie fallow (i.e. not accessed) after the repartitioning.
Code:
before: ...-|-FAC?OR??S-|??ATAFS-|-UMS------------------------------------|...
after: ...-| ? ?? ??|-FACTORYFS-|-DATAFS-|-UMS---------------------|...
\ /
------+-----
|
HOLE
(? = bad blocks)
The calculation is done like the following (Example: N7000_16GB) with X being the size of the HOLE:
Code:
16GB original (Q1_20110914_16GB.pit)
FACTORYFS 548864 ->Fo 1744896 ->Fs
DATAFS 2293760 ->Do 4194304 ->Ds
UMS 6488064 ->Uo 23232512 ->Us
HIDDEN 29720576 ->Ho 1048576 ->Hs
16GB MMC_CAP_ERASE patched
FACTORYFS FoX = Fo+X unchanged
DATAFS DoX = Do+X unchanged
UMS UoX = Uo+X UsX = Us-X
HIDDEN unchanged unchanged
The PITs are named like that:
N7000_16GB_Q1_20110914--patched--brick-between-281-and-2428-MB--FACTORYFS-moved-by-2048-MiB
This PIT is for the N7000 with 16GB and derived from the file Q1_20110914.pit.
Here, the HOLE is from 281 MB up to 2428 MB (MB = 1000000 bytes) which is 2147 MB or 2048 MiB (MiB = 1024*1024 bytes) in size.
So the following relations have to match: BRICK_START >= 281 MB and BRICK_END <= 2428 MB
Note that these numbers are rounded, so if your brick lies exactly on this border, it is possible that your aprtitions are not brick free after the repartitioning.
So to be sure this would be safer: BRICK_START > 281 MB and BRICK_END < 2428 MB
In the example all partitions from FACTORYFS up to the "big" partition (here UMS) have their beginning moved by 2048 MiB.
The "big" partition is shrinked by the same amount, so it ends at the same block as before the repartitioning.
Therefore the following partitions (only HIDDEN in this case) remain unchanged.
All partitions before the first moved partition (FACTORYFS) remain also unchanged.
I recently added more starting partitions for the brick (XXX-moved-by-...).
As a rule, all partitions from this starting partition up to the "big" partition are moved by the size of the HOLE.
All partitions in front of the starting partition and all partitions after the "big" partitions remain unchanged.
Code:
case FACTORYFS-moved-by-...
before: ...-|-FAC?OR??S-|??ATAFS-|-UMS------------------------------------|...
after: ...-| ? ?? ??|-FACTORYFS-|-DATAFS-|-UMS---------------------|...
\ /
------+-----
|
HOLE
case DATAFS-moved-by-...
before: ...-|-FACTORYFS-|D??T?FS-|-UMS------------------------------------|...
after: ...-|-FACTORYFS-| ?? ?|-DATAFS-|-UMS------------------------------|...
\ /
-+-

HOLE
(? = bad blocks)
The PIT file will repartition the phone automatically when flashed using Odin, but the moved partitions will not be formatted after that.
If you flash a partition in Odin, you will also put a valid file system on this partition(because the partition image also contains the file system).
For all other partitions, you have to format those partitions, before you can use them.
At least the data partition should be formatted
The revived phone does in nearly no user noticeable way differ from a stock phone afterwards.
You just have a smaller internal sd (called "big" partition above) and you cannot flash a stock pit file again (this would revert the phone to the bricked state).
ATTENTION: different recoveries and ROMs mount external and internal sdcard on varying directories.
I also had the following problem:
I couldn't format my internal sdcard with the cm9 recovery. I think it's too big for the mkfs.vfat tool of current cm9. So I installed another recovery, formatted the internal sd (I thought).
This erased all my current backups and downloads, because in reality it was my external sd. Fortunately I had a backup of the external sdcard from before rescuing my phone.
So, you may want to create a backup of your external sdcard first.
Then double check which is your internal sdcard (the UMS partition) and which is your external sdcard.
Or you could remove the external sd completely. But think about when to remove it, because you might need it for some files (e.g. to use the emmc partition scanner).
-------------------- backup
before messing with the partition table, everyone should make backups of all partitions that can be accessed.
-------------------- efs backup
The most important backup is the efs partition, which very crucial, it includes your IMEI number, bluetooth MAC etc., and without this individual information, your phone cannot be used as a phone again.
For most supported phones, you can do this via adb:
Code:
dd if=/dev/block/mmcblk0p1 of=/mnt/sdcard/efs.img
please look at forrest1971's thread for details about using adb.
If your phone uses another partition number for efs, then use this instead of the "1" in mmcblk0p1.
Perhaps you have to mount your sdcard first, to be able to save it there.
Then you should copy the backup to your PC (the recovery should have the option to mount usb).
-------------------- backup files from internal sd before repartitioning
the repartitioning will clear all data in the affected partitions, so all data in your big partition (internal sd etc.) will be lost.
You can try to backup your data, if the partition is accessible. The different methods below may have different success, depending which parts of your phone are usable.
* you can use aroma file manager, which is a full fledged gui file manager which starts standalone by being flashed in CWM. So it should be completely independent (sorry, I could not test it for this kind of backup myself).
For the following possibilities you should first ensure, you have a working recovery with working adb support.
Mount your external sd in recovery (which might be /emmc or /sdcard, please check), to be able to copy files.
* you can use QtAdb to copy files to your PC:
* you can use adb pull to copy any files or directory tree to your PC, e.g.:
adb pull /emmc/. emmc
* you can use tar from adb to archive files to a file on sdcard:
adb shell tar cvjf /sdcard/emmc.tar.bz2 /emmc/.
* you can use a copy command in adb shell to copy files to a folder in sdcard:
adb shell cp -ra /emmc/. /sdcard/emmc.backup
Note: you will loose file attributes and owner information if emmc is formatted with ext2/ext3/ext4, because vfat cannot handle these.
This may matter for system and some app related files.
-------------------- recommended procedures for "standard" cases
"standard" in this sense are pits that only affect FACTORYFS, DATA, CACHE or internal SD (UMS/USERDATA etc.).
All other partitions need special considerations and are not handled in this section!
Note these are from theory only. My phone is running now and I don't want to brick it again, only for testing the procedure.
Therefore the procedure is *NOT* tested (by me) and may contain problems which I didn't expect!
So be "careful with that axe, Eugene!"
Note, there are always multiple ways to reinstall the phone.
phase "find brick"
* reboot into recovery (hold Vol-Up + Home + Power until you arrive there [20-30 seconds])
* flash emmc_find_brick_start.zip, note where it freezes -> BRICK_START
* flash emmc_find_brick_end.zip, note where it freezes -> BRICK_END
phase "flash pit and ROM"
* (re)boot to download mode (hold Vol-Down + Home + Power until you arrive there [20-30 seconds], then Vol-Up)
* flash a patched PIT in Odin
* flash a known good ROM via Odin (especially not a faulty stock ICS ROMs)
phase "check partitions"
* reboot into recovery (hold Vol-Up + Home + Power until you arrive there [20-30 seconds])
* check the partitions (see section "checking all partitions" below)
phase "restore partitions"
* switch off the phone (something like "power off" in recovery)
* remove external sdcard (to be sure not to format it afterwards)
* boot recovery (hold Vol-Up + Home + Power until you arrive there [20-30 seconds])
* format cache
* format data
* format internal SD (if it fails read below)
phase "start ROM"
...
After formatting or wiping data you can probably also boot into the ROM and format the internal sd from there (again: keep the external sd removed, to not format the external sd instead of the internal sd unintentionally).
You should be able to flash any stock ROM from samfirmware (click on n7000 under "models"), I would recommend the one you had before the brick and and before any stock ICS, else you risk a brick again!.
I would recommend a cyanogen ROM though, if you can live with some features missing from stock ROM.
Note: I think the standard recovery doesn't give you enough format options (a guess, I am running cm9).
It may be easier to take a custom ROM with a better custom recovery, but it has to be flashable via Odin (tar file).
A second method is via recovery using a custom kernel:
phase "find brick" like above
phase "flash pit and kernel"
* (re)boot to download mode (hold Vol-Down + Home + Power until you arrive there [20-30 seconds], then Vol-Up)
* flash a patched PIT in Odin
* flash a custom kernel with a good recovery (e.g. cm9 safe kernel) via Odin (which will increment the flash counter! -> yellow triangle -> warranty lost until you reset the counter)
phase "check partitions" like above
phase "restore partitions"
* switch off the phone (something like "power off" in recovery)
* remove external sdcard (to be sure not to format it afterwards)
* boot into recovery (hold Vol-Up + Home + Power until you arrive there [20-30 seconds])
* format system
* format cache
* format data
* format internal SD
phase "install ROM"
* install the zip of the ROM
phase "start ROM"
...
So you generally install the ROM like usual, the only difference is to restore all the partitions moved by the repartitioning with the patched PIT.
This is neccessary because all changed/moved partitions don't have a valid file system or content after the repartitioning.
For some partitions this can be done by a simple format (cache, data, internal sd).
Others need true contents (e.g. system, kernel, recovery can be restored by installing a rom/kernel/recovery).
In other cases (non-standard situations) you need to restore a backup (efs, if you have one) or some generic contents (param, sbl1/2).
EFS is the most critical one, because it contains information unique to your own phone. Also see the efs section in this post.
I assume SBL1/2 are needed by the boot process (secondary boot loader), but I never tested this. I don't even know where to get these boot loaders (which probably have to be installed with the PIT via odin, because they are involved in the boot process).
You may find other important information in the thread, please read it completely before asking the same things over and over again.
There may also be useful information and experiences from users.
I try to incorporate useful information in the thread starter, but my time is often very limited.
Also, some information may not look valuable enough for me to integrate it, but it may be valuable for you.
...suggestions or corrections welcome!...
-------------------- checking all partitions for bricked blocks
After repartitioning some partitions may still have bricked blocks inside (because of moving brick or choosing a wrong pit etc.).
Bricked blocks in any partition will lead to random freezes when these blocks are accessed in any way.
So you should check all your partitions after repartitioning to be sure.
With both methods below, you can check the partitions even before formatting any of them.
You can do this with my emmc partition scanner, which is flashed via recovery (this doesn't really flash, it only uses the scripting of the updater mechanism of the recovery, also called edify script).
You can also do it manual via dd commands in adb, but this is much slower.
Use commands like this, using the partition block device in the if=... argument:
adb shell dd if=/dev/block/mmcblk0p1 of=/dev/null
adb shell dd if=/dev/block/mmcblk0p2 of=/dev/null
adb shell dd if=/dev/block/mmcblk0p3 of=/dev/null
...
adb shell dd if=/dev/block/mmcblk0p9 of=/dev/null
adb shell dd if=/dev/block/mmcblk0p10 of=/dev/null
adb shell dd if=/dev/block/mmcblk0p11 of=/dev/null
etc.
If any of these freeze the phone (or reboots the phone or doesn't come to an end even after an hour), you probably (still) have bricked blocks inside the according partition.
-------------------- pit.str for DataWorkshop
For those who want to edit their own patched pit file, I made a structure definition file (pit.str) for an open source multi-platform tool (java) called DataWorkshop, which allows looking at binary data in structured form.
The tool is not very comfortable when it comes to copy/paste etc. but you can edit the values (just put the cursor at the correct digit before typing the number).
Please ask (PM), if you are interested in this.
-------------------- PITs for other devices
Because Samsung doesn't fix their kernels (thinking their software doesn't have the problem) there is a growing number of affected devices.
Look at the attached files, which devices are currently available.
If pits for your device aren't available yet, please send me a stock PIT and tell me which partitions are bricked (or BRICK_START and BRICK_END, and if you know, which partitions are usually bricked for your device).
I'll look what I can do...
I will add comments for special cases below.
-------------------- device i9250 - experimental PITs
I added i9250 PITs which are very experimental, because I don't know how some details of it's stock PIT affect the result. May be it breaks everything, so beware.
I added this especially for Shanava, who said to be able to recover even from a hard brick.
His brick is in userdata.
So this will probably revive the internal sd (is it userdata?) and reinstalling a ROM shouldn't be necessary, only formatting userdata.
But I also added system and cache as possible starting partition for the brick, then you have to install a ROM and format cache accordingly.
-------------------- devices not supported/supportable
i9000, i9300 (and similar):
These devices have a different PIT structure.
The structure for each partition entry doesn't include an offset, so I don't know a way to define a gap for skipping the bricked blocks.
Inserting an unused partition changes the partition numbers after it, which shouldn't work.
-------------------- FOR-EXPERTS-ONLY packages
DO NOT USE one of the packages with "FOR-EXPERTS-ONLY" in it's name unless you are REALLY REALLY sure how to handle/restore/initialize all the affected partitions, often meaning you were involved in the discussion leading to these files or you read this VERY carefully.
These packages contain files to be used by those who have special problems and want to take the risk to try them.
They are only documented by the corresponding discussion (somewhere in this thread).
note: this is a living post, it changes while progressing. If you want to refer to it, please make a reference to the whole thread, beginning at the first post.
Don't directly link to the attached files, as they will go away, when I update the files and their names from time to time.

Repartitioning around the bad blocks
This is the former first post of this thread...I switched it with a continuously updated version, which is more understandable for ths users of my pit method.
-----------------------snip -------------------------------------
Hi everyone, especially those with an ICS brick,
last week I jumped straight into a MMC_CAP_ERASE brick.
Sadly, I knew very well what not to do with a LPY kernel on my phone (wiping etc.).
But one weak moment (touching "wipe data/factory reset" in CWM), and then a moment later a flash (pun!) going through my brain, telling me "wow, now the phone will be bricked, right?".
Well I rebooted the phone and thought to be a lucky man, because the system booted correctly.
But after about a minute the SGN started to get FCs in android.*.acore and Google Play etc. I looked with a root file manager and found that the /data partition wasn't mounted.
So I got the BRICK!
After some days of analysing and thinking about the situation, I found a way out of the dilemma. I think, I will not bother you with all the details of these days, but go straight ahead to the final solution...
(this was planned as the second post in the thread, but the dynamic community inserted many post in between, so I added it here sorry, my fault)
---- cut ----
This is a rewrite in english of my report at a german forum:
ICS Brick, Samsung Galaxy Note N7000, Erfahrungsbericht
www.handy-faq.de/.../249283-ics_brick_samsung_galaxy_note_n7000_erfahrungsbericht.html
My brick created bad blocks in the phone's flash memory.
I got I/O-Errors when attempting to read or write those blocks.
My SGN was still able to boot into recovery and all kinds of kernels/recovery.
Odin was able to flash boot loaders, kernels, modems and CSCs.
But flashing a factory_fs stopped at the very beginning.
I found, that any access to some blocks inside /system and also ANY access to /data left an inaccessible phone and I had to restart it.
For all of the following I needed access to some tools (mainly e2fsck and parted).
As I had completely deleted my system partition before (formatting it), I had no single useful tool around, so the recovery had to provide any of those.
The stock recovery e.g. of KL8 engineering kernel doesn't provide such tools, so I had to find a better one first.
I found all this packed in the Thor kernel, but would not recommend it, because it's closed source.
You may use the tools from forrest1971, see below under "manual method".
One of my attempts to get around those bad blocks, was to create a bad blocks list which can be used by the ext4 file system, I tried this command:
e2fsck -c /dev/block/mmcblk0p9 (which is the /system partition)
Click to expand...
Click to collapse
This failed, because to find out which blocks are bad, e2fsck tries to read them and gets stuck by doing so.
I could have created a list manually, but because the data partition was corrupted starting at it's first block, this bad blocks list wouldn't work here anyway.
At the end, my solution was to recreate the partition scheme, leaving a big hole at the space where /system (893MB) and /data (2147MB) resided before:
Code:
before: - ...-|-FAC?ORYFS-|??ATAFS-|-UMS------------------------------------|...
after: + ...-| ? ?? |-FACTORYFS-|-DATAFS-|-UMS---------------|...
(? = bad blocks, + working, - = not working still bad blocks inside)
In order to not access those bad blocks, I could not move these partitions, but instead I had to delete them first and recreate them at another place afterwards.
So I needed a backup of them first (fortunately I always have 7 Titanium backup levels around).
Here is a log of my steps (but see below in the blue sections for other probably easier procedures):
Code:
I managed to access the device via [I]adb shell[/I]...which is another story for itself...
Then I started [I]parted[/I] with the flash device:
~ # parted /dev/block/mmcblk0
parted /dev/block/mmcblk0
GNU Parted 1.8.8.1.179-aef3
Using /dev/block/mmcblk0

As a greeting I got some error messages about the GPT layout, which parted wanted to fix:

This might mean that another operating system believes the disk is smaller.
Fix, by moving the backup to the end (and removing the old backup)?

this was the partition scheme before implementing the workaround:

11 3322MB 15.2GB 11.9GB fat32 UMS
12 15.2GB 15.8GB 537MB ext4 HIDDEN
then I deleted the partitions 9=FACTORYFS=/system, 10=DATAFS=/data and 11=UMS=/sdcard(internal) and recreated them starting at the former start of the internal sdcard partition (11) leaving the former space of the /system and /data partitions unused:
(parted) rm 11

now I upgraded both new ext2 partitions to ext4:

This configuration works so far (one complete day now).
I can install firmwares and restore backups via recoveries.
Also flashing via Odin should work (not tried yet).
I currently can only imagine one standard procedure which will not work, that is creating a new partition scheme, e.g. via Odin (PIT file) or may be a CWM script.
I think/hope this will not occur too often...
-- naturally, it's much faster to insert those short messages than rewriting a long german post in english.
Next time I should write the main text prior to posting anything, I think...

man has a few posts but are worth a lot. .. thanks for share with us
And... I just wonder it couldn't be possible to recreate the whole partition table with an appropiate tool like GNU/Linux "parted" or so?
Is the damage so serious? Is it physical??
Interesting Read, this should be of a great help to those bricked without warranty.

you *can* indeed try to recreate the standard partition scheme (I did it very early with a PIT file in Odin and also tried formatting those partions etc.), but this doesn't work because *accessing* those blocks in any way is the *real* problem.

yes, you can't even fix the bad blocks with the usual JTAG equipment.
I was told by a technician from a good repair center that a fix could eventually be possible by directly reprogramming the flash chip in some way (JTAG again), but no one tried yet, because this would cause several hours of work...
usually they swap the whole motherboard instead (which is >250EUR)
Thanks, hg42.
I really apreciate your efforts and to share with us.
I'm not a superbriked note owner but I follow with great interest those posts.
Again, thank you, man.
Wow man, that seemed really simple and straight forward. Next week well learn how to copy a file in Android, now that will be much trickier...
Thanks anyway for your efforts!

LOL, you're right, at the end I also thought, that's really simple
but, at least...I had several problems to solve before getting adb up and running properly with root permissions and having the necessary tools at hand (inside adb).
I think this was mainly because I wiped my /system before.
But, it's easy to be wise after the event.
hmm, I tried to export this partition scheme to a PIT file (using heimdall-frontend), but I got a file that is exactly equal to the one I flashed last via Odin, which was Q1_20110914_16GB.pit.
So I assume the PIT file is one way only?
A PIT file would probably allow even unexperienced users to unbrick their phones.
This is the same method here:
http://forum.xda-developers.com/showpost.php?p=26285877&postcount=12
Although your post I found easier to read.
I did something stupid. Got an A200 that could not get OTA 4.0.3, so I managed to get it updated manually. However, I then proceeded to try to root it using the "SimpleRoot" scripts on Acertabletforum, and at this point, the thing is bricked. In Recovery, I cannot get anything to mount. /SDCard, /data, etc
Bootloader is Unlocked
I tried with some different Recoveries with slightly different results:
1) Hbwelch CWM v5.5.0.4 (the one that comes with SimpleTool) - All mounting attempts fail
2) nics-TWRP_stable (twrp v 2.1.4) - Seems to be able to mount System and Cache, but not DATA or SDCARD (Internal or External)
3) thor v 5.5.0x (thor2002ro rev1.7) - errors mounting data, sdcard and /mnt/sdcard. Is able to mount system, cache, flexrom and flex.
Any idea how to fix it? I am afraid that if I try to return the tablet where I bought it as it is now, it will get rejected. (even though the damn thing was supposed to be ICS upgradable in the first place, but wasn't... long story)
Thanks

I finally got the tablet working again. Was very close to sending it back. Got bits and pieces of info from various other posts on this forum and on acertabletforum. For the sake of anyone else that may find this thread, here are a few things that were wrong, and how to fix them
(I cannot post outside links, so just google the file names when relevant)
1) /SDCard would not mount. Solution - PARTITION the SD card. NOTE: The card worked on a PC, and even on that tablet when Android was fully booted. However it would NOT mount in recovery until I explicitly partitioned it. Doing a FORMAT on the PC does NOT count. I had to partition it within Recovery.
NOTE: This may also be why people are unable to get the update.zip thing working.
2) /Data would not mount - I have no idea how this got screwed up, but the solution was:
* Connect the tablet to the PC in RECOVERY. At this point, ADB should work. If not, check the drivers on the PC - I had to manually specify the Acer ADB Composite driver.
* Open a Command prompt window
* Start ADB shell by typing:
ADB SHELL
* Now execute the following:
mke2fs -j -b 4096 /dev/block/mmcblk0p8
tune2fs -O extents,uninit_bg,dir_index -C 1 /dev/block/mmcblk0p8
e2fsck -fy /dev/block/mmcblk0p8
After this is done your file system on /data will be fixed. (solution posted by spoupard on XDA-Developers.com)
3) Putting it all together:
* Flashed the BOOT partition with Honeycomb 3.2.1_boot.img
* Flashed the RECOVERY partition with nics-TWRP_stable.img
* At this point, I noticed that the Bootloader was once again LOCKED. So, start into FASTBOOT mode and execute the following from the command prompt again:
fastboot oem unlock
* Re-Start in Recovery and select MOUNT and make sure that everything is mounted. If /SDCARD or /DATA refuse to mount, fix that issue first (step 2 above)
* Now I select to INSTALL Acer_AV041_A200_1.037.00_PA_CUS1.zip
Upon reboot, I noticed that it said "Updating Bootloader", then got the Acer screen and locked up. I restarted again into Recovery and again selected the option to install INSTALL Acer_AV041_A200_1.037.00_PA_CUS1.zip and reboot. This time it restarted, indicated that it has a new version of bootloader (previously was 3.1.3) and proceeded to boot up into Android 4.0.3. At that point, I think my neighbors heard me scream YES!, considering I spent 2 days on this
I hope I got all the steps. Most of it is from memory and some notes, since I did not want to experiment and go through this hell again.

Great info but you might want to add fixed to the title. For the time being doesn't look like I will be rooting till these issues are sorted out. I am see too many people saying they are bricking with this root method.
FIXED - Acer A200 - BRICKED, cannot mount /data /sdcard

Didn't see a way to edit the title. As for rooting, note that after all was said and done, I am still not rooted. I just managed to get updated to 4.0.3, which should have been done OTA anyway. I may try again now that I am a bit more confident that I can get it back to working state, but will do a full backup in ADB first. Too much of a pain in the *** to have to reconfigure everything again once the OS is installed.
I cannot get the device to connect to my PC at all, or get the correct driver selected. Any tips?

what state is the tablet in when you try to connect? Fastboot, Recovery, or fully booted up and operating?
What do you see in the device manager when the tablet is connected?
ext3 oder ext4?

Try to do this with twrp v.2.1.4: do I use ext3 or ext4 for the Partition? And which size needs the ext Partition?
Thanx

Don't think it matters. I picked the defaults.
mke2fs -j -b 4096 /dev/block/mmcblk0p8
Thanx j_medved for yor reply!
So I did and just faced the next problem: I can conect my Tablet to the PC and can finde it with adb devices and can start the shell with adb shell.
But then when I start: mke2fs -j -b 4096 /dev/block/mmcblk0p8
nothing seems to happen....waited about 30 minutes....
in the next turn I get the reply, that mmcblk0p8 is allready in use....next turn again: nothing seems to happen....
any ideas? .-(

teacherhh,
If I remember correctly, that command should finish pretty quick. You may want to try leaving it for a bit longer, but it seems that you may have something else wrong. I am not that familiar with this area. Haven't dealt with Linux much. Sorry.
Okay. Thanx anyway!

Driver Problems
Hi Guys,
I've the same problem. I can't wipe the Data, so I've found this instruction. unfortunenately will my PC not found my Tab. I've installed the drivers many times, but it will not work. Can anybody help, how to install? btw. fastboot is working, but not adb.
I'm using an Samsung Netbook with Win 7. THe PC's trying to install drivers, altough they are already installed, but can'T find any drivers.
If you need more informations, just let me know.
@Benninator,
If you look in Windows 7 Device Manager, does the device show up there OK? Or does it show up as unrecognized device, or as some device code with a yellow triangle and exclamation on it? Or not at all?
Yes, their is a yellow triangle. I've tried to install the driver manually, but with no success. In my driverlist were the Acer driver not listed. furthermore I've tried to configure the usb-adb.ini with also no success. I have absolutly no idea what I can do.
In device manager, and does it show up as a200 or unknown device?
Is the device I am recovery at the time?
And also, and which recovery?
Tab is missing recovery and won't boot in to android

HOW TO AVOID BRICKING YOUR TAB
The best advice I can give to people who haven't bricked their tab (already?^^) : DO NOT EVER WIPE ANYTHING WHILE RUNNING STOCK 7.7 ROMS
Here is what to do in order to flash a custom rom safely when coming from stock :
- Flash the latest cwm with ODIN
- Do NOT wipe anything
- Flash the custom rom of your choice
- Reboot recovery
- Wipe what you need to wipe
- Re-flash the custom rom
- flash the gapps or whatever
- Reboot, done.
Ok guys, I'm seeing more and more people bricking their 7.7 and, being one of the unlucky owners of a bricked p6810, I understand how stressful and annoying it can be.
I've been reviving my tab like a hundred times using this technique, as you'll most likely have to re-do that whole process everytime you wanna flash something.
There are two ways of reviving from superbrick I know of :
- The first is to flash a PIT file with ODIN that will repartition your tab for you.
I will not cover this method as hg42 already wrote a very detailed tutorial about this. This tutorial is about Galaxy Note but you can appIy it to our 7.7 and you'll find PITs for P6800 there. I will soon make pits for P6810 using the scripts provided in hg42's guide.
- The second way is to repartition your tab manually through adb. This is the method I'll try to teach you here.
Let's first be very clear :
- This won't get your tab back in its former state
- Your internal storage will shrink by a lot
- All your data will be lost
- No guarantee it works for you
- You'll most likely have to do that every time you flash
- Your tab might rebrick itself after some days, so you'll have to do this again, get used to it.
- If you can get Samsung to repair your tab then go ahead
- I'm not responsible for any further damage made to your tab
- You need a computer for this tutorial
Ok, you read the above carefully ? You are ok with it ? then let's begin !
Using the Android Debugging Bridge (adb) to revive your tab
Setting up your environment
Prior to anything, you need to download and install the android sdk, I won't cover the installation here, it's explained on developer.android.com and there are plenty of guides on how to get adb and the sdk on xda.
Make sure you install the platform-tools in the sdk manager.
Ok now I assume you got the sdk installed, so let's move on to the serious things.
1) How to open an adb shell ?
First, you're going to need the latest ClockWorkMod Recovery (a.k.a CWM), download and instructions on locerra's thread here
Then boot your tab in recovery (Maintain power+volume up buttons) and plug it into your computer via usb.
Then do the following :
a- On Windows
Navigate to the directory where you installed the sdk, and open the folder called "platform-tools" (e.g : go to C:\android-sdk\platform-tools if your sdk is installed in C:\android-sdk)
Press shift and do a right clic on an empty space in the folder, then select "open a command prompt here" (or something like that).
b- On Linux
Open a terminal window (ctrl+T)
Let's assume you put the sdk in a folder called "android-sdk", located at the root of your home folder (~/android-sdk).
Then you have to enter this in the terminal :
Code:
cd ~/android-sdk/platform-tools
So now, all the rest of the commands you'll have to enter are the same on windows and linux, as the adb shell will actually be running in your tablet.
2) Meet a new friend, he's called parted.
First, we are going to use parted to take a look at our partitions and their file systems, and eventually replace the corrupt partitions with clean, freshly created ones.
Then, you'll meet your other very good friend with a barbarian name : e2fsck (e2 stands for ext2, and fsck for file system check. Not that barbarian finally is it ?). He will check your filesystems and fix the possible errors they got.
Ok now we've made the presentations, let's go !
First make sure you read the following :
In the code boxes of this tutorial, there are symbols at each line start, DO NOT COPY IT with the rest of the command ! :
-the "$" represents your bash shell or command prompt
-the "#" represents the adb shell
-the"(parted)" represents the (parted) shell
-Each end of line means "press Enter".
-The partitions numbers are not the same on p6810 and p6800 (please report to this reference), so there will be two code boxes in the examples, one for p6810 and one for p6800, it's indicated in bold red but make sure you don't mix it up, that could screw your tab even more.
Ok here we go !
Issue the following in your terminal/command prompt :
Code:
$ adb shell
# parted /dev/block/mmcblk0
(parted) print
The output should look like this :
>>> P6810 <<<
Code:
Number Start End Size File system Name Flags
1 4194kB 25.2MB 21.0MB ext4 EFS
2 25.2MB 26.5MB 1311kB SBL1

10 15.3GB 15.7GB 470MB ext4 HIDDEN
11 15.7GB 15.8GB 8389kB FOTA

The superbrick MMC_CAP_ERASE bug that affects our tab apparently only corrupts the /system and /data partitions (sometimes, /cache can also get corrupt in the process, I cover this in the last part of this guide, "extra cases").
Your emmc chip on which resides those /data & /system partitions is corrupt at some places.
To give you an example, think of it as a chain of dashes :
Code:
-----------------------------------------------------
This dash chain is divided in two parts (our /system and /data partitions), I'll symbolize their length with "[]" for /system and "()" for /data :
Code:
[----------](-------------------------------------------)
So that's how it was on your tab before brick, but now it's bricked some blocks (the dashes "-" here) are corrupt. I'll symbolize them with "?" :
Code:
[--??--???-](--???-?-----------????-----------??-?--??--)
Now you figure the workaround don't you ? We need to move our /system & /data partitions to places that are clean, at the cost of reducing their sizes :
Code:
--??--???---???-?[-----------]????(-----------)??-?--??--
We will strive to give /system its original size, or something close to it, while we can sacrifice more of the /data partition.
Ok, enough theory, let's move on to practice.
Here, in parted, /system = FACTORYFS and /data = DATAFS
We are going to remove the /data partition first, so we have some space to work on.
Enter the following :
>>> P6810 <<<
Code:
(parted) rm 9
>>> P6800 <<<
Code:
(parted) rm 10
Now please refer to the output of (parted) print you had earlier, just scroll up a little in your terminal window. See those Start/End values ? Well check the end value of your DATAFS partition and remember it.
Here's an example for P6810 :
Code:
9 *START -->*1137MB 15.3GB*<-- END* 4163MB ext2 DATAFS
So now comes the boring part. We are going to try to make a new clean /data partition.
Seems easy but the problem is :
- if you try to make it too big, it'll get stuck and return an I/O error.
- if some blocks are corrupt between the start/end values you'll enter it will get stuck and return an I/O error.
In both cases you'll have to reboot recovery and re-enter this in your terminal :
Code:
# adb shell
# parted /dev/block/mmcblk0
So this is long and boring to find the right place and the right size. Don't be greedy on the size, as long as you get at least 150-200mb it's cool, you'll be able to expand that later.
First you're gonna try to put the original end value (15300 in the p6810 example up there) as the new end value. So for the same example, if you wanna try to make a 500mb /data partition, you're gonna use 14800 as start value and 15300 as end value.
Ok let's go (this is still an example for p6810, for the p6800 owners, use your own (parted) print results) :
Code:
(parted) mkpartfs primary ext2 14800 15300
It will output something like this :
Code:
writing per-group metadata : XX %
Here there are two options :
- You were lucky, it will complete up to 100% and return "(parted)", which case you just have to enter the following :
>>> P6810 <<<
Code:
name 9 DATAFS
>>> P6800 <<<
Code:
name 10 DATAFS
- You were not lucky, it got stuck before reaching 100%, which case you have to reboot your recovery, re-enter parted and try again with a smaller start/end gap, or reducing the end value, you got about 14gb of space to try to make your partition, so it's sure you can find somewhere to put your small partition, just requires some blind testing.
Just remember to try to put your /data partition quite close to the end (original end value), so you still have some space to find somewhere to put your /system partition.
So now we'll assume you managed to have mkpartfs complete till 100%
Type this to see your updated partition table :
Code:
(parted) print
Now we're going to repeat last step with the /system partition.
Issue this :
>>> P6810 <<<
Code:
rm 8
>>> P6800 <<<
Code:
rm 9
The /system partition is much more important than /data, so you want to try to have its size remaining the same (872mb).
At first, you can try to re-make the /system partition with the same start/end values. It's not likely to work but it's worth trying.
Here's an example on P6810:
(again, if you're on P6800, then use your own start/end values for the 9th partition (FACTORYFS), you get them by typing print in parted).
Code:
(parted) mkpartfs primary ext2 264 1137
Same thing here, if it doesn't complete, then reboot recovery, type :
Code:
$ adb shell
# parted/dev/block/mmcblk0
And repeat this step until you find somewhere it works : (where YYY - XXX = 872)
Code:
(parted) mkpartfs primary ext2 XXX YYY
Remember to limit your research between FACTORYFS original start value (264 for P6810) and the new DATAFS start value you made, so you keep the order of the partitions.
Once you found the right place (where "writing per-group metadata" completes till 100%), type this :
>>> P6810 <<<
Code:
name 8 FACTORYFS
>>> P6800 <<<
Code:
name 9 FACTORYFS
The hardest part is done, if you type this you should get a full table of partition, make sure no number is missing or disordered (1,2,3,4,etc...).
Code:
(parted) print
3) Meet another good friend : e2fsck
Now we've done our fresh and clean partitions, you must be thinking we're done, but we're not ^^
In fact the two partitions we made are using ext2 filesystem, but the /system partition's filesystem should be ext4 (like it was at the beginning).
There are two ways of converting an ext2 filesystem to ext4 that I know of :
- Simply formatting /system in cwm recovery will convert the filesystem to ext4. To do this, just head to "mounts & storages" and select "format /system".
If it gets stuck while formatting, reboot your recovery by pressing the power+volume-up buttons for about 15 seconds, and head to the next part, you have to do something before you can try to format it again.
- Or issuing this in terminal :
>>> P6810 <<<
Code:
# tune2fs –O dir_index,uninit_bg,has_journal /dev/block/mmcblk0p8
>>> P6800 <<<
Code:
# tune2fs –O dir_index,uninit_bg,has_journal /dev/block/mmcblk0p9
To make sure either of the two ways worked do this :
Code:
# parted /dev/block/mmcblk0
(parted) print
And look if FACTORYFS shows ext4.
If it does, reboot recovery, then on to next part. If it doesn't, then still reboot recovery and head to next part, after which I'll redirect you here to try again.
Now we are going to use e2fsck to check our new partitions for errors, but not only, it also fixes some erros and it will even for example create lost & found in /data
So let's go, we'll begin with /system. If you're still in the (parted) shell, use ctrl+c and type "adb shell", then issue the following :
>>> P6810 <<<
Code:
e2fsck -yfDC0 /dev/block/mmcblk0p8
>>> P6800 <<<
Code:
e2fsck -yfDC0 /dev/block/mmcblk0p9
This might take long, or not, this might get stuck, or not. Either way reboot recovery if it gets stuck or whatever, but do it again till it finishes properly.
This is what my /system e2fsck final output looks like (p6810) :
Code:
/dev/block/mmcblk0p8: ***** FILE SYSTEM WAS MODIFIED *****
/dev/block/mmcblk0p8: 2636/53312 files (1.2% non-contiguous), 101948/212890 blocks
If you got 0.0% or like less than 5% in "(X.X% non-contiguous)" this is a good sign.
Now reboot recovery and let's do the same for /data :
>>> P6810 <<<
Code:
# e2fsck -yfDC0 /dev/block/mmcblk0p9
>>> P6800 <<<
Code:
# e2fsck -yfDC0 /dev/block/mmcblk0p10
Same thing here, if it gets stuck then reboot recovery and do it again.
Here you should get 0.0% non contiguous. If you don't, in cwm do wipe data/factory reset, then reboot recovery and do this e2fsck again.
Ok now you got both clean e2fsck, (if you still have an ext2 FACTORYFS then now is the time to go back to try converting ext2 to ext4 again)
Make sure the e2fsck still are clean by doing this (it should be quick this time) :
>>> P6810 <<<
Code:
# e2fsck -cy /dev/block/mmcblk0p8
# e2fsck -cy /dev/block/mmcblk0p9
>>> P6800 <<<
Code:
# e2fsck -cy /dev/block/mmcblk0p9
# e2fsck -cy /dev/block/mmcblk0p10
Now you should be nearly good to go ! :laugh:
Download the cm9/cm10-based rom you want, make sure you check known issues and that you like this rom because everytime you'll want to flash a rom it's likely you'll have to do the whole e2fsck part again, or even sometimes the whole guide.
Now reboot in recovery and flash the rom. Two options :
- it flashes, then reboot, pray and be patient, if it takes more than 15 minutes to boot first time, then reboot it again, do this a few times if it doesn't boot, it might eventually do. If it doesn't, then reboot recovery and redo the e2fsck command for both /data and /system, let it fix things if it has to, then reboot again. Anyway it should have booted by now.
- flashing gets stuck : make sure you waited at least 5 minutes then reboot recovery---> wipe data/factory reset---> wipe dalvik cache---> reboot recovery---> adb shell and redo the e2fsck on both /data and /system, then try flashing again.
DO NOT FLASH THE GAPPS NOW, that will screw all you just done ! If you need the gapps then head to the following section of this guide.
4) Installing the gapps
If you flash the gapps after flashing the rom you'll be screwed, you'll have to redo the e2fsck part and maybe even the parted, and I know you don't want to.
So the workaround is to add the gapps to the cm-based rom you downloaded.
It's easy, just follow me :
Open the zipped rom you downloaded with 7zip or WinRar (Windows), or with Archive Manager or else (Ubuntu). Do not extract it, we'll modify the zip directly.
Do the same with the gapps, so you have both archive side to side.
In the rom, you have boot.img, and two folders : "META-INF" and "system". We will modify things in "system" folder ONLY. Open "system" folder.
In the gapps we will only use things from the "system" and "optional" folders.
The rest is pretty easy to figure out. In the gapps's "system" and "optional" folders you have folders which have the same name as some folders in "system" of the rom.
Just copy/replace everything that is in those folders of the gapps to the corresponding folders of the rom. Don't forget to do that with both "system" AND "optional" folders of the gapps.
When it's done just close the freshly modified rom, copy it to your tab's external sdcard and flash it.
If you don't have an external sdcard, then reboot recovery, copy the rom to the "platform-tools" folder of your android-sdk and rename it rom.zip.
Then return to your terminal and do the following :
Code:
$ adb push rom.zip /sdcard
It will now be in your internal sdcard (remember you shrinked it earlier so make sure the rom doesn't take all the space).
5) Expanding your internal storage
I don't recommend you do this the first time you follow this guide.
It might screw your /data partition so you have to do the whole process I describe in this guide again.
Anyway if you wanna try, this allowed me to earn a few extra gigs (never managed to get back more than 4gb and boot).
Here's what to do :
>>> P6810 <<<
Code:
$ adb shell
# parted /dev/block/mmcblk0
(parted) resize 9
>>> P6800 <<<
Code:
$ adb shell
# parted /dev/block/mmcblk0
(parted) resize 10
This will output something like :
Code:
Start ?
End ?
writing per-group metadata : XX %
You can only move the end value in fact, trying to change the start value will return an error. Try doing this to earn like 250mb at a time so it doesn't get stuck. Good luck.
6) Extra cases
If when booting in recovery, the recovery says something like "can't read /cache/recovery/last-log, Read-Only file system" then your /cache partition is corrupt.
Then you'll need to recreate it with parted. /cache is quite small (209mb) so it should be easy to have "writing per-group metadata" finishing.
Here are the commands to remove and recreate /cache with parted (it's the same on both models) :
Code:
$ adb shell
# parted /dev/block/mmcblk0
(parted) print
(parted) rm 7
(parted) mkpartfs primary ext2 XX YY (where YY - XX = 209 and YY < FACTORYFS start value)
Nice guide...dude. Thanks for sharing
i being running e2fsck -yfDC0 /dev/block/mmcblk0p10 on my p6800 since yesterday this time. till now still show error reading block *******<attempt to read block from filesystem resulted in short read> while getting next indoe from scan. ignore error? yes
force rewrite? yes
question now is should i let it keep running or change to e2fsck -fDC0 /dev/block/mmcblk0p10 ?? hmm

Not sure but this "attempt to read block resulted in short-read" error remembers me of my own brick, I think it's the error you get when you can't mount /data in recovery's mounts & storages.
Try to mount /data and if recovery can't mount it, then u need to recreate your /data partition with parted, like it's explained in this guide.
e2fsck alone won't fix it if it's not mountable.
Just talking from my own experience, but there might be other ways.
two questions:
1) i read something about having to back up the /efs partition? as it contains your bluetooth mac id and your emei number before flashing any alternative pit file
2) when i try to start the android SDK installer it says "Java SE Development Kit (JDK) no found. </br> Error: Failed to find Java version for 'C:\Windows\system32\java.exe,' blah blah blah"--is it because i tried to install the jdk 64-bit?
---EDIT--- solved the installation problem. setting up android SDK now...

Well yeah you can backup your efs but if you follow exactly this guide there's no way you can mess up your efs, as it's the first partition and we only deal with partitons 8 to 10.

I guess e2fsck won't run if the partition you check isn't mountable.
But you're right that e2fsck can't fix everything, the method I describe is drastic but it works.
So Josvaz, if after running e2fsck - try any options you want, won't harm (but add -y so it answers yes to all and you can go have a coffee) - you see more than 2 or 3% in " XX.XX% non contiguous" then remove your partition and recreate it using parted's mkpartfs, and re-run e2fsck, it should now be clean (0.0% non contiguous) and you can flash on it and boot your tab if your /system is clean (or close to) too.
Good luck.

- The first is to flash a PIT file with ODIN that will repartition your tab for you.
I will not cover this method as hg42 already wrote a very detailed tutorial about this. This tutorial is about Galaxy Note but you can appIy it to our 7.7 and you'll find PITs for P6800 there. I will soon make pits for P6810 using the scripts provided in hg42's guide.

but if i use this method, do i need to back up the /efs partition? i guess, i need the experience with abd, and its certainly not going to hurt anything if i do, and didn't need to. so i'll try that and see if i get a response in the mean time.
hg42 said:
You should be able to flash any stock ROM from samfirmware (click on n7000 under "models"), I would recommend the one you had before the brick and and before any stock ICS, else you risk a brick again!.
Note: I think the standard recovery doesn't give you enough format options (a guess, I am running cm9).

is this possibly a way to avoid having to go through this process every few days or so?

Yeag for the PIT method, backing up your efs is wise, although the PITs won't mess with it normally. But yeah, can't hurt to back it up.
You don't need no experience with adb to flash a PIT, just know how to use odin, download the pit for your particular model (eg : p6800 16gb) put it in odin's "PIT" slot (the first slot), make sure repartion IS ticked, click start and let it flash.
giving up lol .. any thing i need to do before i send to samsung ? like original pit, rom etc? anyone have original pit file ?

the efs back up, is that used from within adb, or flashed as part of a recovery or? in other words, how do i use it?

It's not done from adb, some apps allow you to backup/restore it (eg : Voodoo Sim Unlock for sgs3), check out the thread I linked earlier.

Yeah whether hc or ics, for some reason, samsung devs thought it was a good idea to include mmc_cap erase a.k.a superbrick bug in their kernels.
Anyway I doubt you'd love to stay on y

yeah I don't think that i will keep using hc for long, but consider that most isc roms are pipi-caca (wifi issues and battery drain) Ill wait for some stable builds (just like overcome on my beloved "sold" GTP1000).
I think that dedraks made a new kernel which is without the brick bug ? is it safe to use with hc ??
and thanks for the great work you're doing on the new galaxy tab 7.7 (merci beaucoup !)
so i have not figured out how to get a working pit file flashed. there are so many, and i VAGUELY understand his numbering system, so i figured i'd start with the smallest available space first, because that one would be the most likely to account for any bad blocks. i tried nearly ALL of them. now i'm trying to test to see whether adb is able to access ANYTHING-- (tab is booting into recovery and download, and adb detects the device from windows) however, what i'm getting is "/sbin/sh: parted: not found" is that saying that parted cant be found or that parted cant find the reference block? researching this now.
so obviously, i've had to sit down and warm up to your NOOB GUIDE!!! its very clear, i just havent done this level of anything with android, tho what better way to learn than sink or swim? problem is, i'm an artist, and pretty broke.... my computer fried months and months ago, and i just decided i'd rather spend my extra cash on the gTab 7.7 cus is the largest affordable sAMOLED to date, and well, a 30% expansion of the standard color model really appealed to me, so the only thing i have to work on is my super bricked tab!!! a friend of mine is lending me her laptop while she's at work, and i'd like to try to fix it this evening.... ughh....
if anybody can help me figure out my way through this tutorial, i'll be researching why 'parted' isn't working.
THANKS!!!
---UPDATE
okay, so for some reason, i can't seem to push files from adb to the device. from what i've read, i have to manually install parted to sbin, (or there's a flashable kit available also) but i can't figure out how to get it to pick up the file (its in the folder with ADB.exe, so i shouldn't need to reference the path for the copy location, right?)
now i'm looking up general "ADB device navigation and testing"

Disconnect and reconnect phone.
To check phone is still recognized:
Code:
adb devices
Then:
Code:
adb shell
Commands start with # (again, we are in shell).
Type and wait during operation:
Code:
mke2fs -t ext4 /dev/block/mmcblk0p21
Code:
mke2fs -t ext4 /dev/block/mmcblk0p22
Code:
mke2fs -t ext4 /dev/block/mmcblk0p23
Code:
mke2fs -t ext4 /dev/block/mmcblk0p24
Code:
e2fsck -f /dev/block/mmcblk0p21
Code:
resize2fs /dev/block/mmcblk0p21
Show new partition layout with fdisk (slightly different):
Code:
fdisk -l /dev/block/mmcblk0
(You can still do the same with parted: /tmp/parted /dev/block/mmcblk0 > unit s > print)
Now system (part 21) is ~1400M, cache 384M, userdata ~20G and storage a few M.
Code:
exit
Disconnect phone.
8) FLASH AOSP 11
Go to Mount > check Data partition and connect phone.
From Windows: copy ROM + GApps (+ Magisk, optional) to the same phone's Internal Storage folder.
Back to TWRP: go to Install > aosp-11*.zip
Then go to Wipe > Advanced Wipe > Resize File System > Swipe to Resize.
Go to Reboot > recovery
Baxk to recovery, go to Install > flash bitgapps*.zip.
9 ) DEVELOPER MENU
Open Settings menu > About Phone.
Tap on the "Build number" entry seven times. You should be notified, that the developer settings are now active.
Now go to Settings menu > System > Advanced Developer settings.
Scroll down and change transition and animation scales to x 0,5 for smoother animations.
You can install GBoard or Swiftkey to change the keyboard.
That's it.
Enjoy,
djibe

Good.

Well, why ext2 for system ?
You have exact same partition layout as me.
You should delete and recreate those partitions:
21 655360s 2752511s 2097152s ext4 system
22 2752512s 3538943s 786432s ext4 cache
23 3538944s 10878975s 7340032s ext4 userdata
24 10878976s 61071326s 50192351s ext4 storage
Good point, i didn't notice that ext2.
EDIT :
This is weird, even if I use the ext4 format on the system, after installing the ROM it will print on as ext2.

You can reformat with TWRP later: Wipe > Advanced Wipe > System > Change File System > EXT4

Hi, thanks for sharing.
Looks cool but without documentation.
partition_unified_single.xml seems to have suitable System partition size.

Just flash flash_partition_table_and_core.bat with MiFlash Tool or flash_partition_table_and_core.sh on Linux
And yes is a suitable system partition size.
Hi guys,
So good to see that someone still have this good old device! If you are interested @GuaiYiHU has also published an Android 11 rom for our device on his github : https://github.com/tiger-cave/local_manifests/releases/tag/android-11.0.0_r43
Who knows, maybe he will also do the magic with 12

So, I use my mi2 only for these experiments now but it boots without problems. I have of course resized the system partition to install gapps. GPS is not working since years, most probably it's a matter of hw failure. FM radio and camera works just fine even if quality has decreased drastically in the last years. Haven't tried mobile signal as I don't have a sim installed but WiFi works ok. Hope it helps. All the credits to @GuaiYiHU that has done a super job.
I tried to revive my Mi 2S, followed the steps, but I'm stuck on boot screen. After 1 hour still no movement, so that's not OK
I tried to flash the latest stock rom, but this did not help either, the device starts up in fastboot.
Any advice?

Hi,
your repartition layout is like the final one here ?
TWRP boots OK ?
Thanks! Works like a charm
