[Q] Semi-soft hard non-brick - just looking for ideas

Anyway, I was using Miui V3 2.4.20 [2.6.35], and Google maps wasn't very happy with it. So I decided it was time to move on to the .32 kernal version, since the developer was going that way too. Downloaded a stock rom with .32 kernal, went to the pink screen and flashed, and then boot loop.
Luckily, I'm awesome, so my phone won't die on me. Tried flashing some roms through clockwork, no bootloop, just stuck at huawei logo. Tried flashing some stock roms, and at about 98% done flashing it goes error. Some parts get flashed causing my recovery reverts to stock, but I'm still stuck at the huawei logo.
Also, in clockworkmod I get errors mounting data and emmc, so that might be a problem. Other partitions mount fine.
I'm sure I'll find a solution eventually, so there's no rush. I've been in similar situations before. Just wanted to see what other people had used for similar situations. So if you know of something that would help, please let me know.
Found these through search (I'll do a better search again later), i will try them tomorrow:

After reading a lot of threads, attempting to flash a lot of roms (stock and others), replacing all kinds of images, and offering a sacrifice to the cellphone gods, still at the same problem:
To reiterate problem:
1) Stuck/reboots at Huawei logo
2) Flashing stock roms via pink screen never finish installing, get error message at ~95% finished (During install, unpacks fine)
3) Flashing roms via recovery say they installed, but still boot problem
4) This problem occurred while trying to downgrade from .35 to .32
My next step is to try using Linux to put the Dload folder on the internal SD card and try installing from there. I have a feeling it is related to the partitions having problems. I used both the "get back pink screen" and "data partition resize," maybe something went wrong with them that only appeared when I tried to go back to stock. I'll find out more when I install linux and can see if the partitions are OK or not.
I've always wanted to try linux, and now that my phone is broke I have found the motivation to do so. So a word of advice for people for people wanting to try linux but are too lazy to download the linux file: Soft-brick your phone, it gives you motivation.
UPDATE: I'm pretty sure my partition table is broke pretty bad. In adb shell, df gives me:
Filesystem Size Used Free
/dev 173M 64K 172M
/system 203M 200M 2M
/cache 127M 4M 123M
and that's it. No /HWUserData, /.cust_backup, /mnt/asec, /mnt/obb, or /data.
Would someone be as kind as to tell me how to fix the partition table? I've got a soldering iron, duct tape and super glue. Also, I'm not afraid to buy a "box" to do some Jtag stuff.

Anybody know what Blefish uses to format the phone memory? I read on his tumbler page and his github that he has altered the partition table (he split the /hwuserdata into three sections, which means he has the ability to create partitions) If I can get that tool, then I have a plan:
0) If my understanding is correct, the updates don't install because the needed partitions are missing, which causes an error. I guess the updates won't create partitions, just alter them.
1) Use the tool blefish used to setup the partition table as described in this thread: http://forum.xda-developers.com/showthread.php?t=1504488
2) Once the partitions are back, i should at least be able to get the blue screen, if I'm good, then I can put all right files in /dev/sdb1, which will get me the pink screen.
3) Using the blue/pink screen, I can install stock firmware, which should correct any problems that the partition table has. Maybe even install android.
4) Do the happy dance
5) ???
6) Profit
I've done my homework, searched the forums, made a plan, and cleaned my room. Someone please give me some feedback and at least let me know if I'm heading in the right direction.

I am using fdisk, the main partitioning tool for MBR table. You can check the table by doing fdisk /dev/block/mmcblk0 and then "p" which should print the current partition table. From there, you can also modify the partitions.

Awesome. I used to use fdisk back in the dos days, so I just need to brush up on my skills and learn the adb specifics. I really need to take the time to go learn all the commands associated with adb.
INTERESTING UPDATE: If I flash a rom with locked boot loader, I still get the pink screen but it doesn't work, i.e. I can't access the image folder via windows. If I flash a rom without a locked boot loader, pink screen works. Granted none of these roms actually fully flash, I still get the error near the end.
Fdisk = Permission denied, su = permission denied. Rooted boot image prevents me from getting into recovery, which means adb won't work. Any other way to get root? I'll try flashing a custom rom when I can get clockworkmod working again. For some reason I can't get recovery to load via vol+ & power.
Also something weird is going on. When it boots, it reboots once, then goes to stock recovery, tries to do a factory reset, gets errors on formating. Also in windows two removable disks appear, but I can access them. I take it that they represent the internal SD card and maybe the pink screen image folder partition. Tomorrow I'll try linux and see what happens.

UPDATE:
1) I can't use FDISK because SU won't work. I'm not sure how SU/root works on a software/partition bricked phone.
2) Rooted boot.img won't boot into recovery. SuperOneClick won't work because it can't find the data partition (probably because I don't have one).
3) I was going to try flashing a custom rom but for some reason I can't get clockworkmod working again. The phone will boot into stock recovery on it's own, after a couple of reboots. However, if I change the boot.img or recovery.img to anything else, it gets stuck at huawei logo or boot loop.
4) Unbuntu LiveCD won't work (says it can't find the kernal) even though I used the installer from the website and tried it both via cd and flash drive. Working on installing a dual-boot system now.
I'm really striking out here. Couple of questions if anyone would care to answer.
1) Besides recovery, how else can I establish an adb connection? Pink screen and huawei logo give me device not found.
2) Is there a root exploit available that doesn't require a data partition or is there a root exploit I can modify so it doesn't require a data partition? It's OK if it's a manual exploit, while I'm new with android/adb, I got plenty of experience with command prompt input from back in the dos days.
Also learned there is a HuaWei office in my town. Don't know what they do there, but if I don't make any progress after I couple more days, I'll go find out.

On pink screen, your device is just like any other mass storage device. So you can still use fdisk on ubuntu with the correct /dev/sdX path. You can also format the data/system/cache using other tools if you need to.

Sweet, so I just need to get Unbuntu working. I still can't figure out why the live CD/flash drive didn't work. Oh, well. When I get off of work I'll get to installing the dual-boot system. Thanks for your help.

Thanks. Unfortunately the project is on hold for a couple of days. My electric motorcycle has been having some problems and I've been repairing it. Also, I think I found out why linux wasn't working. Apparently the "alternative" downloads aren't useable as a live CD, which is why the kernal wasn't there. Anyway, it's been a great learning experience. Maybe after I "break" my phone enough times I'll learn enough to become a developer.

Doing some research before getting back to working on the phone.
Looks like Blefish is talking about using linux's fdisk, when I was trying to use adb's fdisk. That would certainly allow me to bypass the su problem with adb. I think I got all the correct files for my linux livecd, so that shouldn't be a problem. After I'm done with my workout, I'll try it out and see how it goes. It's time to learn how to use linux.
Update: Got unbuntu working. Storage devices are all /media instead of /dev like I was expecting. But I think I'm not looking in the right place.
Plugged in phone via pink screen and 3 drives came up:
System - has system stupp (app, bin, etc, fonts, ...) - sdb12
256 MB File system - image folder with all the .img and .mbn files - sdb1
136 MB File system - has fotapkg, lost+found, recovery folders- filesystem type ext3/ext4 - I'm not sure what this is, maybe sdb6? If it was data (sdb13) then I wouldn't get the error in recovery, If it was the internal SD card the filesystem should be vfat. If someone knows better, please let me know.
For some reason I don't have permission to access the lost+found folder, or so Unbuntu tells me.
Tried to used fdisk with system, got error: I don't know how to handle files with mode 40755
Also found some recovery log files in the fotapkg and recovery folders. I'll post it here incase someone can get some more useful information out of it. Does anyone know what all these (null) mean?
Tomorrow I'll get to work on learning how to use unbuntu and fdisk.

It could be that the data partition (originally mmcblk0p13) got wiped out and now mmcblk0p13 is internal sd card. Here's the original partition table:

The sdb6 is indeed cache, and it is used for recovery communication between Android.
If everything would be ok, it would mount sdb1, sdb6, sdb12, sdb13 and sdb14 inside Ubuntu, so it seems that something is wrong at the end.
If you have 14 partitions, use disk utility from Ubuntu and try manually formatting the 13 for ext4 and 14 for vfat. Taking ownership is not needed, it should work either way.

Blefish, thanks for the help. Got unbuntu up and working along with fdisk and identified the phone.
I have 13 partitions (including one empty one) , not 14. Here's the print out:

Comparing with your partition table I see two differences:
1) the ending block of sde1 is 491520 on mine and on the original it is 30721, however the blocks are the same, so that is probably not a problem
2) sde13 is empty, and sde14 is missing.
This actually makes sense. When I was using MIUI, I reduced the size of the internal sd to near zero, since MIUI could only either the internal or external sd, not both. After trying to downgrade, I had a problem, so I tried to restore the internal sd card back to stock size, just to bring my phone back to stock. Something must have gone when I did that.
So if I understand the problem correctly, to fix this I need to:
1) Split sde13 into 2 partitions
2) Format sde13 to ext4 and sde14 to vfat
3) Try installing adroid again
Do I need to name the partitions a certain name or do anything else?
In the mean time I'll be looking into how to use disk utility and fdisk to deal with sde13 and sde14.

Had an idea that I only need sde13 (data) to get things working again, the system shouldn't need sde14 (internal sd) to work.
So I went to disk utility, found Qualcomm MMC storage and tried to format the free 2.9GB at the end. Got an error:

So, my partition table is corrupt? I'll need to figure out how to fix this.

Here's some options I've found:
http://forum.xda-developers.com/showpost.php?p=21572216&postcount=12
ksatta mentions a couple of ideas:
1) If someone backed up their phone using dd, I could use that to restore my phone.
Here's a link on how to do it: http://linuxpoison.blogspot.com/2009/04/creating-backuprestore-images-using-dd.html
dd if=/dev/sdX | gzip > /home/sdX.bin.gz
where sdX is the U8800
2) I could clone someone's partition table. If someone could give me a copy of their MBR that should work.
Here's a link on how to do it: http://embraceubuntu.com/2005/10/20/backing-up-the-mbr/
Create a backup of your MBR by doing a:
dd if=/dev/sdX of=MBR-backup bs=512 count=1
That should read “create a disk dump of the input file, which is /dev/sdx (change to hda, or hdb or sda, depending on where the MBR is on your computer), and save it in the output-file MBR-backup in the directory from where the command is issued. Backup the first sector only, while you are at it”.
3) gparted - it's some kind of partition tool. Might be able to use it to fix the error. Not sure how to use it though.
For now I'm going to look into gparted for Ubuntu. If someone can help me out with a dd backup or cloning the partition table that would be awesome.
UPDATE: For people following this thread, and to keep me more organized, I'll start adding more of the important resources I find. They may one day help you fix your phone.
https://bugs.launchpad.net/ubuntu/+source/gparted/+bug/434463
Seems a guy fixed his the same error with gparted. However it wasn't on a phone. Also I'm seem a lot of people refer to sfdisk. I'll need to learn more about it.
https://answers.launchpad.net/ubuntu/+question/113539
"I got an answer in a forum, which looks easy.
Do a
sudo fdisk /dev/sda
then type
w
to write partition table, without any modification of it.
The signature should be fixed."
Is this safe to do to my phone? I know I'll have to write the MBR eventually, but I have to get it right the first time. If I screw up, I may not be able to connect to ubuntu anymore. Anyway, the guy said it fixed the error with his harddrive, so it's worth a try.
http://www.thegeekstuff.com/2010/09/linux-fdisk/
How to use fdisk, in case anyone needs to know
So my new plan is to:
1) dd Backup and MBR backup - in case I break it worse than it is
2) try to fix with fdisk w or gparted

I think the change in start and end is caused by Ubuntu using cylinders/sectors/blocks. Should not too much difference though.
Using MBR restore would not work here, as it restores the main 4 partitions list. MBR uses EBR aswell, which is located at the beginning of every extended partition. So we would have to copy the EBR of every partition.
I'd suggest deleting sde13, adding sde13 and sde14.
When adding sde13, note that starting block should be at the end of sde12, so simply insert last block of sde12 there. If it gives error, simply press enter as it automatically finds free block after the last one. End block could be for example +500M so fdisk automatically finds the correct end block. Do the same for sde14, but note the start block again. sde14 end block should be the last block there is on the card.
After you've done that, do w to write and if it tells you to restart or something, unplug the phone, take out the battery and restart to pink screen again. Then try to use disk utility again or gparted (have not tested this) to reformat sde13 and sde14 to ext4 and vfat.
You should be safe until you don't mess with the primary partitions, especially the mmcblk0p2 and mmcblk0p3.

Thanks again for the reply, Blefish. I may have just fixed it. I'll know soon enough.
I did two things:
1) sudo fdisk /dev/sde12 followed by w
2) sudo fdisk /dev/sde followed by w
After that it enabled me to add the 13 and 14 partition. I used disk utility so I didn't have to worry about the blocks. Afterwards they mounted in ubuntu like they should.
UPDATE: Not quite fixed, but the rom installed without error. So I think the partition problem is fixed.
Now I just have a boot loop. I'll go back to ubuntu, clear the cache, and try installing from the internal sdcard
2nd UPDATE: Stock recovery gives and error about mounting the cache partition. However CWM mounts it fine. My partition problems may not be over.
3rd UPDATE: genokolar's "Custom you partition" file to return to stock file deletes my partition 13 and 14. Had 13 and 14 back working, used the file as per instructions, afterwards ubuntu drive utililty shows 13 and 14 as "free." So that is where part of my problem comes from.
4th UPDATE: Fixed the problem with stock recovery. Turns out froyo doesn't like ext4 partitions. Changed cache partition to ext3, no more error.

Here are some exerts from the CMW log when I tried to flash cyanongen. Can anyone tell me if any of these errors are problems, and if they are what they mean?

My phone is fixed. I have no idea how it became fixed, but it is fixed.
I placed b518 on the internal sd card, and installed it. Then bootloop. So I held both volume keys+power to try another rom. It installed again. Went to recovery, it did a factory reset. Bootloop. Went back to recovery to see if I could wipe the sd card. No option for it, so I did another factory reset and rebooted my phone. I left my phone bootlooping for a minute while I looked online for a Huawei service center, and then my phone booted. I gues it got scared and didn't want to go to a service center.
This been a great learning experience, although at times a major headaches. I want to thank blefish for all his help. Thanks to this, i've bee reading his blog and other stuff, and now will follow some of his other projects.
Now to downgrade back to 2.2!!!!
UPDATE: All official roms are working correctly (b136, b138, b518, b528), recovery (5.0.2.6) works. However I haven't been able to get a single custom rom to work. Tried a couple .32 MIUI and CM, but they all stick at the huawei logo. Did factory reset and dalvik wipe, get error can't mount /sd-ext during dalvik wipe, and still doesn't boot.
Maybe I need to try a newer verison of CWM? I tried the newer versions before, and I didn't like them. Buggy and often wouldn't find my sd card.

This thread must be made sticky because it consists of pure information about dealing with soft-bricks. Thanks a lot for your curiosity, you're my hero.

Localization of bad blocks?

Hello,
is there a (simple) way to get the location of the bad blocks, based on their hex address reported by mtty / info 8 ? Maybe without the need to install the ROM from scratch and save the log file?

...nobody?

i was wondering if my device has developed any bad blocks the other day. so the next time i had to restore my rom from a backup, i decided to look into it, using whatever steps/concepts i could remember.
i wanted to know which partition(s) had bad blocks, as opposed to a raw address that has to be interpreted later on. i remembered reading here that ClockworkModRecovery's "recovery.log" will contain this information when a partition or all partitions are formatted.
so i have a habit of formatting all partitions (except sd's FAT32) before i restore a backup. i did so and told CWM to copy the recovery.log to my sd's FAT32. perhaps you can use the same approach, i.e. take a CWM backup, then wipe all partitions, copy the recovery.log, and restore your backup. effectively, you will get your rom back just the way you left it and you will have determined if your device has bad blocks and how many and in which partitions.
then i continued with the restore.
when i had time later on, i opened the "recovery.log" i had copied earlier and noticed that it contained the following (notice the part in bold+underline below):
Code:
-- Wiping cache...

so i guess that part means there is a bad block in my data partition...of course some other partitioning could make the bad block land in some other partition.
but what i remember reading here on xda is that the phone's internal NAND management avoids bad blocks until all "spare" blocks are used up. after that, software (i.e. ClockworkModRecovery) can mark blocks as bad at the filesystem level...so really nothing to worry about (i think!) unless there are so many bad blocks that you have to "expand" one or more partitions' sizes to compensate for the bad blocks.
i hope the above helps...!

[Q] Nexus 7 (2012) Stuck in a boot loop, recovery fails from being read only

Hi and thanks to anyone who decides to help me as my knowledge is limited.
I decided to flash KitKat as I play a WebView based game and thought the WebView Chromium of KitKat might make it run faster as it ran pretty slow. On the Paranoid Google+ page it says you need TWP 2.6 later and other sites say 2.6.x. I had 2.6.0.0, so did a backup of boot, data, system and recovery using TWRP, copied them to a PC and then tried installing KitKat, it failed. So I updated to TWRP 2.6.3.0 and it failed again, tried a second time and it updated
The game didn't work well on KitKat, so I restored my original version. I then decided to take screenshot of game not working on KitKat to complain, so tried installing KitKat again forgetting to update to 2.6.3.0 as the restoration of the backup restored the prevous 2.6.0.0 recovery, was a noob and tried again and i'm now left with a Nexus 7 in a boot logo loop.
Restoring the backup fails, as does installing the KitKat Zip or Opensensation . If I try flashing TWRP 2.6.3.0 via fastboot, it says success, but when I reboot the recovery i'm still in 2.6.0.0. I can boot into 2.6.3.0 using "fastboot boot", but it still won't restore the backup or flash. I also have a backup of the OpenSensation rom (wanted to try PDroid and it was the only rom I could find prepatched) which I made on 2.6.3.0, that won't restore either.
The error i'm getting in TWRP is "symlink: some failed"", "can't open destination log file: '/cache/recovery/log'" and "E:Unable to open '/cache/recovery/log'"
This is the end part of recovery.log in tmp

But It has no effect. It's still stuck in a boot loop and if I reboot into recovery it's still TWRP 2.6.0.0. I can browse data/data using ADB sh and all data still hasn't been deleted. When using ADB, I can push files to root but once I reboot the device they are gone. If I do ADB Shell mount after attemping to install someone via TWRP I get
Code:

If I then go into the mount menu and remove ticks in boxes and put them back I get

but if I try writing to cache, system, sdcard, data, it instantly switches back to ro and faiils. ADB push says it succeeds and file appears on device when it is mounted as RW, but is gone on reboot.
If I boot into recovery TWRP 2.6.0.0 and type adb devices, I get
Code:
List of devices attached
0123456789ABCDEF recovery
Which obviously I know is iffy.
If I do fastboot boot <TWRP 2.6.3.0>
and do adb devices, I get
Code:
List of devices attached
015d2109a660180c recovery
If it means anything, previously i've taken screenshots on the device and deleted others. Then connected to a PC in normal mode and what I see in the screenshot directory was from before those changes.
If it also has a bearing, when I connect the Nexus to the PC it tells me it can perform faster when connected to a USB2.0 port which it is. It Also has the power recharge problem, to get it to recharge I have to plug the usb cable in, remove usb cable and reinsert within 10 seconds, turn the screen off and leave it alone. As solution posted on Google Forums, but it used to charge normally.

I had a similar problem the other day and used the toolkit to flag an even earlier build (4.2) and I could boot.
Then do the OTA updates which will update your bootloader and then reflash whatever you like.

Thanks for your suggestion, unfortunately if I flash any stock which doesn't have the same boot loader as the device already has the flash fails. I get
Code:
writing 'bootloader'...
FAILED (remote: ())
so no error code and fastboot crashes after a couple of more steps. I can't write to the device at all, formatting, erasing does nothing even if it says it was successful. in TWRP I can't delete any file or change the permissions on any file.
So it's not something I know about, but i'm assuming the boot loader gets verified straight after being flashed, as my device will still have 4.23 regardless of what's being flashed the verification fails and fastboot on both the PC and Nexus 7 crashes. On the Nexus 7 in top left corner I see 'Signature Match'.
I also can't relock the bootloader. If I do "Fastboot OEM lock" it says success, If I immediately then try "Fastboot OEM Unlcock" it says it can't be done as device is already unlocked. It's like it's a hardware write flash failure, but it's a very big coincidence it happened when I was using TWRP.
Also tried removing the battery connector for a few minutes, did nothing.

Did you get anywhere with this? I've got the same symptoms - it "pretends" to flash partitions, but does nothing. Same error trying to downgrade the bootloader.
The installed OS has become flakey because its state never changes - it seems the whole device is stuck in read-only mode.
I'm suspecting its a write off
Oh - and I don't think its to do with TWRP - I had CWM installed, but I hadn't done anything but used the device for about a week - I have stock 4.4 + CWM + Superuser - and was happily using it until today when it started rebooting whenever I write much (like install updates). I think something about the flash has just "gone bad" - or perhaps been marked as non-writeable.

Same here..
I have experienced same problem.
My N7 is in Groudhog Day mode!
Whatever I do it reverts to its condition a fortnight ago... before rebooting.
It goes through all the motions... but Groundhog Day after reboot.
Must be hardware I think.
Any comments?????

Has anyone managed to solve this? I'm having the same problem. Bootloops and whenever I try to wipe data in TWRP (factory reset) it doesn't actually wipe anything. Help!

I've followed this up with Google Support (I bought the tablet from the play-store), and with it in the warranty period they offered an RMA replacement. They didn't have any hints or tips other than attempting to boot in safe-mode and factory reset the device (first-level standard support script), after factory reset failed they offered replacement.
This is only of help if your warranty is still in good standing - hint they were only interested in drop-damage or water-damage - unlocked bootloaders are no problem - although (a) I'm running stock and (b) Australian consumer law may give better protection than other locations.
Breaking news is that my wife's tablet failed in exactly the same way 3 weeks later. Her's had only ever been stock - in fact its bootloader was locked until the KitKat OTA reported errors applying due to mismatched system APKs. I suspect that was the first sign of bad flash. I unlocked and flashed stock KitKat. Then had ~3 weeks of no problems, now this. Hope that helps someone.

Has anyone managed to solve this? I'm having the same problem. Bootloops and whenever I try to wipe data in TWRP (factory reset) it doesn't actually wipe anything. Help!

Well, just an update. Same problems still persisting. No solution yet. I contacted Google support but as I'm outside of the warranty period, I'm S.O.L.
Anyone with some other ideas?

Just adding a "ME TOO!". Makes me feel better that I am not alone... No matter how I flash, it says its successful, but on reboot, all is as it was before flash... Suppose I could get a Nexus 7 with a broken screen and fix it now... :/

I may consider myself lucky : it is late 2018 and my good old Nexus 7 2012 has fall into the Groundhog Day mode a couple of months ago... No way to flash, erase data or reset... Even erasing my personal files when connected to a PC doesn't work : all files are back after reboot... Bye bye Cyanogen ROM...

Turns out the read only issue is a known issue of hardware failure. I did end up replacing the motherboard and it was a good decision. Not too expensive and not super hard to do. I use an ASOP Nouget build.

[SCRIPT] Fix partition table for Android 4.4

Since the gapps for 4.4 need very much space wee need bigger system partitions.
I've created a script which automates this process and increases them both to 840MB.
the space is taken from the userdata partition.
You should backup your whole phone before doing this(storage will not be touched but you shouldn't take the risk)
I tested it with 32GB version only so if you want to know if it will work for 16gb, too give me the output of this command:
parted -s /dev/block/mmcblk0 print
Download:
http://d-h.st/FWz
Instructions:
1) boot into CWM
2) adb push repartition.sh /tmp
3) adb shell chmod 0777 /tmp/repartition.sh
4) adb shell /tmp/repartition.sh
5) adb reboot recovery
6) now you can do all the usual stuff like enabling TDB and installing ROM's

Sounds great but I cannot test it, since I dont have any parted binaries (at least in my 4.1.1 Wajk Wiui ROM) ? Can you please tell me where I can get them.
Second Question:
Im currently running TDB:
System 1 latest WIUI 4.1.1 v5 ROM
System 2 MIUI v6 1.9.19
Both system partitions are completely full (usage 98 %) and the same with the data partitions ( usage 97 % )!
Would it be possible to decrease /sdcard space and repartition it like the following with TDB enabled:
system 800 mb
system1 800 mb
data 1500 mb
data1 1500 mb
sdcard *the rest*
thanks in advance

sounds like you tried to repartition from Android
You need to boot to CWM - you have parted there.

Sorry I hate people who just ask stupid questions before reading the instructions carefully ...silly me sorry for that...
What about the second question, is it possible to either increase the data partitions for less space on /sdcard ?

there isn't sth. like a data1 partition. we have one data partition only that's why we need the TDB hack.
other than that it's possible but you should backup all your data and restore it afterwards.

Ok got it.
So following your instructions and editing script like the following should work ?
Code:
change_table() {
ui_print "parted: delete"
parted -s /dev/block/mmcblk0 rm 23 || return 1 # system
parted -s /dev/block/mmcblk0 rm 24 || return 1 # system1

parted -s /dev/block/mmcblk0 rm 26 || return 1 # userdata
parted -s /dev/block/mmcblk0 rm 27 || return 1 # storage
ui_print "parted: create"
parted -s /dev/block/mmcblk0 mkpartfs primary ext2 336MB 1176MB || return 1

parted -s /dev/block/mmcblk0 mkpartfs primary ext2 6515MB 31.3GB || return 1
ui_print "parted: name"
parted -s /dev/block/mmcblk0 name 23 system || return 1
parted -s /dev/block/mmcblk0 name 24 system1 || return 1
parted -s /dev/block/mmcblk0 name 25 cache || return 1
parted -s /dev/block/mmcblk0 name 26 userdata || return 1
parted -s /dev/block/mmcblk0 name 27 storage || return 1
return 0
}
Code:
ui_print "format partitions"
for NUM in 23 24 25 26 27
do
if ! format_partition "$NUM"; then
ui_print "Failed format partition $NUM"
exit 1
fi
done
already did full backup of sdcard, i just dont know if i should disable TDB before i stat repartitioning ... I dont know how TDB works to split the data partition thats my problem :/

yes that should work.
You don't need to disable TDB because your whole data partition will be wiped and it stores the TDB configuration(that means that TDB automatically gets disabled).

Had some errors but now its working fine ..thanks

unmount sdcard in CWM. It's a bug of this script.
Nice to hear it works now.

7 days ago Phone not start because partition corrupt
Hello
First do not panic is not the fault of your script but for you experience with mi2s and partitions are the few people in the world that can save my phone.
I'm playing a game phone(Xiaomi m2s 16GB) hang and one or more partitions are corrupt (I think this is the problem). But all de documentation than i find to delete o edit partition not work. Fastboot rom installation all ok but always only start with white logo. Mirecovery works perfectly and CWM by ivan works but temporally with this command sudo fastboot boot recovery.img

Can you explain a little more? Does it only leave 1 system partition? Can I flash it like a regular zip?
Enviado desde mi MI 2S mediante Tapatalk

any step by step manual how to change partition? with all necessary downloads etc...
or.... is it possible to delete system2 with all its parts? - for me I'd to use system1 only

Why can not I change the size of the system partition?
Already tried several times, with disabled TDB and with enabled TDB.
Full wipe did and still no result.
P.S. I have already been able to do any repartitioning.

PS C:\Android> adb reboot recovery

UPD. The problem was that I was using Windows Povershell
Run the script from the command line and everything turned out.

Thanks!
I have to format first system and system1 in recovery to apply this script, because I have and error :
tmp/repartition.sh lin 115 can´t create /sdcard/parted_12_06_2014_FDFD6F4CB043F4956D9CAD053C3738AA.

DO MOUNT your SDCARD
then Follow the instruction
duhh...

I modified the script a little bit for 1 ROM usage. System1 is 840MB as in the original and System2 is 5MB. The rest goes into userdata. This is for the 16GB version.

Ok! I did again and umount the sdcard abd it worked fine.
Thanks

I found a better way
If u reboot into dload mode, u can change the partition table from your computer
The problem is that most partition managers don't support changing the GPT Partition names and that's why I added support for that to GParted.
GParted supports booting from Live CD/USB so Windows/Mac users aren't left out.
http://i.imgur.com/3SwSXs2.png
I pushed the patch to GParted repo's and I'll inform u once there're any news.

from my point of view the best way for use is:
- system (system1) - let 1024 MB
- system1 (system2) - let 10 MB
- userdata (apps) - let 4096 MB (take it from sdcard) - but maybe more

Corrupt partition /data

Okay so I recently updated my s4(att) from cyanogen 12 to cyanogen 13 (latest nightly). I went to settings/security and chose encrypt phone. After about 30 minutes of encrypting it reboot and got stuck in a bootloop. I thought no problem Ill just reflash. I go to reflash my backup and it says error mounting /data. I try formating data, factory reset, and installing the rom from scratch. It seems my data partition corrupt. So I figure fastboot. Yet upon loading fastboot I cant get adb to see my device. I think I got the right drivers installed. But nothing. Any help would be greatly appreciated.
Edit: fixed.
Solution:
I found this and was able to shell in via adb and format the partition.
f you wish to wipe the /data partition completely (including media like photos), follow the below instructions:
Boot into recovery.
Run adb shell in a terminal (Linux) or Command Prompt ("CMD", Windows). After a few seconds, you should see a line containing ~ #.
WARNING. Triple-check the command that you are entering here. White space and capitalization are important. Make any mistake here and you may accidentally wipe your whole flash memory including recovery images.
NOTE: if you want to encrypt your partition later, you have to leave 16KiB unallocated space on the end of the partition.
In the adb shell, run the command mke2fs -t ext4 /dev/block/mmcblk0p12. Substitute /dev/block/mmcblk0p12 and ext4 according to the recovery filesystem table (for /data). Output when running the command:
~ # mke2fs -t ext4 /dev/block/mmcblk0p12

Reconfigure device, choose language, enter name, install apps, etc.

of course always check your formatting the correct partition first
