[Q] Unable to mount /data - Acer Iconia A500

hey guys,
i have a huge problem with my Iconia A200. (I know its a a500 forum, but I think they are nearly the same..)
When I enter TWRP, I am not able to mount or wipe /data.. It says "Unable to mount /data".
I cant even install a Custom or Stock Rom (because of blabla /data).
Then I tried to follow this guide:
http://forum.xda-developers.com/showthread.php?t=1798652&page=3
The problem is point 2:
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)
When I enter mke2fs -j -b 4096 /dev/block/mmcblk0p8 after "adb shell" nothing more happens.
It only says mke2fs 1.41.0 (DATE..2010 or something) and then.. Nothing more.
Can someone help me to fix the /data problem?
Ah and I dont have a ROM installed yet, hard reset is broken, too..

[HOWTO] Fix for corrupted internal SD-Card

Today (03312011) we've fixed a corrupted sdcard for real!
On your Phone:
1. parted /dev/block/mmcblk0
2. print and write down
3. delete all partitions
4. recreate partitions (see point 2)
5. format mmcblk0p1 with vfat
6. format mmcblk0p2 with ext4 (example: mke2fs -q -L data -b 4096 -m 0 -F /dev/block/mmcblk0p2)
7. reboot
Done on CyanogenMod 7.
Code:
* daemon not running. starting it now *
* daemon started successfully *
~ # umount /dev/block/mmcblk0p1
umount /dev/block/mmcblk0p1
umount: can't umount /dev/block/mmcblk0p1: Invalid argument
~ # umount /dev/block/mmcblk0p1
umount /dev/block/mmcblk0p1

halp!
edit: I can manage to navigate the phone, i just cant execute some of these commands....
Nice job...now..someone with a i9000m and bad internal SD needs to try this to see if it fixes the issue...if so...we found our solution!
I have the corrupted SD card. Can't access from Android but I can mount it in ADB and all the files are there.
When I try this:
echo /dev/block/mmcblk0 > /sys/devices/platform/s3c-usbgadget/gadget/lun1/file
or this:
$ dd if=/dev/zero of=/dev/mmcblk0p1
dd if=/dev/zero of=/dev/mmcblk0p1
dd: can't open '/dev/mmcblk0p1': Permission denied
I get permission denied...
Any other ideas?

Looks like those devices aren't mounted, so you can't umount them.
type 'mount' to see a list of already mounted devices.
If the devices aren't mounted then you can skip onto the next step.

You need to 'su' first.
OK, luckily I can still boot into Darkys ROM and su is there.

Is this error a problem?
OK, after: fat.format /dev/block/mmcblk0p1
"success to format"
damn, no change - still get the "damaged internal SD card" message.
must be some missing some mysterious Samsung-specific partition data. Can see the entire SD card through adb. Just can't mount it in Android.
Any other suggestions?
I did get the same problem a few weeks ago but after performing a format with in the settings menu it got fixed, will bookmark this thread though incase it happens again and regular format does not resolve it.
Code:

you should mount it via usb to your pc and format with windows.
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
1. Flash Kernel with ADB-Support while at Recovery: h t t p://w w w.multiupload.com/3SVI4OBTD9
2. Boot into Recovery
3. adb shell
4. umount /dev/block/mmcblk0p1
5. umount /dev/block/mmcblk0p2
6. echo /dev/block/mmcblk0 > /sys/devices/platform/s3c-usbgadget/gadget/lun1/file
7. In Windows simply right click the desired Device and format it. No Quickformat! Will take 2 Hours or more.#

theres no instruction which says "use fat.format"
Yeah but the problem is it cant umount because it returns

i think my phone is just downright screwed
First post here, hi all.
I am also having an SD Card issue on my Bell galaxy s ( have no external SD cards installed, only the 16GB internal).
History:
I upgraded from 2.1 (downloaded OCLF from Market, installed Insanity 0.93 and then to 0.94 (which has sataloop set to null under advance lagfix menu) and all was working great).
Then i decided to flash: SO_zImage_opt_ext_root_JPM-JP6_V4_2_OC.zip kernel (found here: http://forum.xda-developers.com/showthread.php?t=811660 ) via Odin and on reboot, i could not get past the galaxy S screen (buttons would stay lit).
In the clockwork recovery screen i got the message:
E: can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk1p1)
No such file or directory
Error mounting /mnt/sdcard/!
Flashed to I9000UGJH2-PDA-Kernel-Bootloader-CL490514-Low.tar (stock ROM)
still unable to get past galaxy S screen (buttons would stay lit) and had the SD card error in recovery screen.
I ended up flashing with Eugene's Eugene_2E_JK2_Froyo.tar.md5 and pit 512 (did not check repartition)
and i am able to boot back into OS 2.2
However my SD card is showing blank or unrecognized format.
I have tried the steps in this thread and i am getting the following output in adb shell:

Skipping format...
Done.
I can see the drives in Windows 7, but when i right click the drive to attempt to format it from windows i get the message: Please insert a disk into drive.
I am currently running Eugene_2E_JK2_Froyo and i tried formatting the SD card from within the phone menu but nothing actually happens, the SD card shows 0.00B of available space, if i try to download a market app i get the message not enough space.
Any suggestions?
Thx in advance!
Get it for repair... No joke nothing can be done sd card is partially dead . I got the.same problem
Sent from my GT-P1000M using XDA App
~ # fdisk -l /dev/block/mmcblk0
fdisk -l /dev/block/mmcblk0
fdisk: can't open '/dev/block/mmcblk0': I/O error
I said "if partitiontable is ok go on".
Your partition table isn't ok.
-> Samsung support!
~ # fdisk -l /dev/block/mmcblk0
fdisk -l /dev/block/mmcblk0
fdisk: can't open '/dev/block/mmcblk0': I/O error
so I guess it's back to bell right?
Question about FDISK:
Seems like I need su to execute fdisk. Problem is I can only give su permission from Android. Except in Android, I can't mount the sd - I can only mount it from within CWM. Does fdisk require the sd to be mounted?
I can mount and navigate the sd card using CWM and from adb (when CWM is running) just fine and access the files.
Is there no way to repair the partition table?
I'd be willing to offer a bounty for this, and I'm sure others would as well.
TIA
For those who have "Internal SD Damaged" at boot and mount error in recovery.
Try flashing JPC with repartition using 512 pit.
I did just that to fix my damaged internal SD.
Thanks StoneRoses - tried this many times with no luck.
Will try again just for fun. (back shortly)
................
OK, done - same error as before:
E:Can't mount /dev/block/mmcblk0p1
(I/O error)
E:copy_dbdata_media:Can't mount SDCARD:
:-(
I had the "Can't mount SD Card" issue, i tried a number of different combinations of flashing about 5 different firmwares (with variations of repartitioning, and not, etc.).
Nothing worked for me, couldn't mount in adb either. I finally sent it back via Bell (I bought my phone outright from T-Booth, I'm not a bell customer at all, was using unlocked on Rogers). They sent it back for me, but I am waiting to hear that they either have it back, or I have to pay more to get it fixed... We will see!

[HOW-TO] Make Ext4 from Recovery Without Losing FAT32 Data

I've seen a lot of threads detailing how to create an Ext4 partition using Gparted but if you don't want to download the image and would rather do it all on your phone, here's how:
This entire procedure should take less than 5min so you can go back to messing with your phone in other ways.
REQUIRES:
CLOCKWORK MOD RECOVERY
ADB
FINGERS
I am not responsible for any damage done to your phone doing this process. =.=
1. Download the zip file provided.
2. Extract the zip file to the same folder you have ADB in. (You should now have a folder named ext4 in the same folder you have ADB)
3. Reboot the phone into MAGDLR. Then select the option to boot into the recovery.
4. Make sure that /system/ is mounted using the option to mount partition in Clockwork Recovery.
5. Open a command (cmd) prompt and cd into your folder with ADB.
6. Run these commands in the command prompt. (Commands are in BOLD)
adb push ext4 /system/etc/
adb shell
parted /dev/block/mmcblk0
print (make note of the total size of your partition here)
resize 1 0 xxxx (where xxxx is the size you want for your FAT32 partition. It should equal total size of your partition that you gleaned from print minus 1024 for the ext4 partition you're about to set up)
mkpartfs primary ext2 xxxx yyyy (where xxxx is where your previous partition ended and yyyy is the total size of your sdcard)
.... (Let it do its thing. Shouldn't take more than a minute)
print (Make sure that everything is correct: You have a fat32 partition running from 0 to xxxx and an ext2 partition running from xxxx to the total size of your partition)
quit
Now to utilize the two files we previously pushed to /system/etc/
chmod 777 /system/etc/tune2fs
chmod 777 /system/etc/e2fsck
/system/etc/tune2fs -j /dev/block/mmcblk0p2 <- You now have ext3
/system/etc/tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p2 (Note: CAsE SEnSitiVE)
/system/etc/e2fsck -fpDC0 /dev/block/mmcblk0p2 (Note: CAsE SEnSitiVE) <- You now have ext4
7. You can check that it's truly ext4 by:
parted /dev/block/mmcblk0
print (It should now read that you have a FAT32 and an ext4 partition.)
quit
You're all done! Now you have a 1GB ext4 partition for all your data and apps. If you know what you're doing, these same steps can be modified so that you have two ext4 partitions if you'd like. You can also alter the size of your ext4 partition to something smaller if you don't have that many apps to install or have a smaller SDcard (512MB should be sufficient in most cases, 1GB is slightly overkill IMO)
i will try with my HD2. I need more space to install app on sd not on phone. Thanks so much
Hi, I follow your instruction but when I get a "Permision deined" error when I type in the following commond
/system/etc/tune2fs -j /dev/block/mmcblk0p2
Can you please help?
Many many thanks!!

Crap. I forgot a step. You have to type
chmod 777 /system/etc/tune2fs
chmod 777 /system/etc/e2fsck
prior to using those files. That should fix the permission denied error.
I've edited the OP to reflect the changes, thanks for pointing that out.
Thanks man
Thanks Bro I have successfully make ext4 and I am enjoying my new Rom
Using HTC Desire runnymede 5.0
Amazing. I will keep it for future reference, although I partitioned my SD with CWM recovery and Gparted.
What kind of partition is made when using CWM? I made a 1GB partition on my card that way, and it works great. But I've heard good things about having it as ext4. How does this guide reflect the fact that I already have an SD-EXT on my card that's not necessarily ext4?
Thanks!
please help
please help me i cant get it to work... its same with /system mounted and unmounted...not even one 3rd app is working for me on my win 7 64x when i want to create ext4 this is my last hope. card is brand new 8gb ultra speed its working fine so cant be problem there. it seems like chmod 777 will delete that file..
Code:

Hye... I have 2 question...
My phone is a HTC HD2 running an NexusHD2.ICS.CM9.HWA.V2.3 ROM... The cmd prompt cant seem so fine my device. Do have any advice on this???
Secondly, what do i do with the ext4.zip file??? I mean, do it extract it, or put in same folder with ADB??
Btw, i am Super Noob on this, so i apologize if my question offends anyone... 1000 apologizes...
OK, first of all, do you have adb installed correctly? If cmd prompt can't find your device that is the most likely problem.
As for what to do with ext4.zip, you need to extract it to your adb folder.

[SOLVED] EFS empty - no Backup - no lockscreen/powermenu - EMEI works

Hi guys,
A friend of mine recently rooted his I9505 and tried to install a custom Rom.
He made an Nandroid backup of his Stock rom but TWRP wasn't able to mount /efs.
So he ignored it and made a Backup without checking /efs.
As he installed a custom Rom he did something wrong and wasn't able to boot system.
So he went back to stock rom.
The Problem now is that his /efs folder is empty and he has no lockscreen and powermenu.
But the strange thing is that he has no problems with IMEI or Baseband.
Is it somehow possible to get his /efs files back?
Or at least get his lockscreen an powermenu back working?
He would be even happy with and alternative lockscreen and powermenu. maybe a app?
I hope someone can help us
Thank you very much in advance for your answers
SOLVED:
I tried many different methods so i don't really know which one worked.
But here are several methods you can try if you have the same problem:
Method 1:
Code:
su
busybox mount /efs
echo -n ON > /efs/FactoryApp/keystr
echo -n ON > /efs/FactoryApp/factorymode
reboot
Method 2:
Code:
su
mke2fs /dev/block/mmcblk0p10
mount -w -t ext4 /dev/block/mmcblk0p10
echo -n ON > /efs/FactoryApp/keystr
echo -n ON > /efs/FactoryApp/factorymode
reboot
Method 3:
Code:
su
mount -w -t ext4 /dev/block/mmcblk0p10
echo -n ON > /efs/FactoryApp/keystr
echo -n ON > /efs/FactoryApp/factorymode
reboot
Try them all and one of them should work
Try a factory reset. If that doesn't work odin to stock should get you fixed up

Thank you.
I don't have the phone here so i'll try it tomorrow and see what happens.
Your mount command didn't work because you are using the /system/bin/mount that is a part of Android. This version must get the device name and the mount point, you cannot omit one of them (with busybox mount you can omit one or the other).
I had the EXACT problem and already started a thread.
There was a lot of help given to me, try reading through my thread mate.
http://forum.xda-developers.com/showthread.php?t=2388663
In the end it turned out my EFS partition was so corrupt it had to go to service centre.

[HACK] Grow your data partition

THE PROBLEM
As many of us have noticed, it is fairly easy to get an "Out of space" message when installing apps on our phones because, for some weird reason, Oppo decided that the storage part of the device should linger in the dark ages, when /userdata and /sdcard were separate partitions and you only had 2GB of data storage, even if your phone was a 32GB model.
Now, imagine that you are running KitKat and would like to try ART. This may be a bad idea as, if your data partition is more than 30% full, you will find that while converting your apps to this new format, Android will run out of space.
At OppoForums, a few bright people started looking into the issue and, of course, there is a way to improve the situation.
WARNING!
If you follow the steps below correctly, you should not run in any trouble. If you do not, however, you may end up spending much more time fixing your phone.

A USB cable
On your computer:
adb
[Optional] fastboot
On your phone (SDCard):
parted + mke2fs + tune2fs
mmcblk0p21_persist_ext4.img
openrecovery-twrp-2.6.3.0-find5-TP-patch.img
[Optional] gdisk
You will use parted to work on your partition table; mke2fs and tune2fs to create ext4 filesystems on some of these partitions (parted does not know how to create ext4 partitions)
mmcblk0p21_persist_ext4.img is an image that you need to restore your /persist partition and avoid issues such as non-working WiFi.
openrecovery-twrp-2.6.3.0-find5-TP-patch.img is a patched recovery image. I know: you already have a recovery image if you are going through these steps. However, we are going to wipe it so you want to install this guy before rebooting. Note that if you forget, you can always flash it later using fastboot.
On your computer:
adb to access your phone recovery, push files to SDCard, reboot...
[Optional] fastboot. You will only need fastboot if you mess up your recovery partition.
WHAT IF SOMETHING GOES AWFULLY WRONG?
You may “brick” your phone. Apparently it’s near impossible to hard brick your Find5, though. See below.
First, Anders recommends making a backup of your partition table. I didn’t because I felt that if I messed something up, it would be a partitions’ content rather than the partition table but that’s not the wisest approach.
Furthermore, if you are really worried about what stilly error your fat fingers will cause (I know I should be!) you can also backup your partitions.
Backing up your partition table:
On your phone:
Code:
gdisk -b /sdcard/gpt.bin /dev/block/mmcblk0
Backing up a single partition:
On your phone:
Code:
dd if=/dev/block/mmcblk0p<partition id> of=/sdcard/backup-<partition id>.bin
On your computer:
Code:
adb pull /sdcard/gpt.bin
adb pull /sdcard/backup-<partition id>.bin
LAST RESORT
OK. So, you've bricked your phone. Now what?
First, you will need Windows. So if you're on a Mac or Linux and have no access to a Windows machine/VM, er..don't brick your phone.
- Download drivers and tools
- Download and follow the instructions
READY ? LET'S GET STARTED
>>>>>>>>>>>> First, Download The Files <<<<<<<<<<<<
Then...
On your computer:
UPDATE As dixxa pointed out, mke2fs and tune2fs may already be present on your device. It was not the case for me but you should check first; it seems like a good idea to use existing binaries.
Code:
adb reboot recovery
adb push parted /sbin
adb push mke2fs /sbin
adb push tune2fs /sbin
On your phone:
Code:
chmod 755 /sbin/parted /sbin/mke2fs /sbin/tune2fs
umount /cache
umount /sdcard
umount /emmc
umount /data
parted /dev/block/mmcblk0
You are now in the parted shell.
CAREFUL! Do not delete any partition below 20 or you will enter "Big Oops" territory. I recommend typing carefully and, yes, staying away from copy/paste operations that may swallow a character like, say, the '2' in '20'
Note that the size value I am using here is '4GB' for /userdata (rather than 2GB). I guess you could make /userdata bigger than 4GB, in which case you would have to recompute all the offsets in the commands below(!)
Code:
# rm sdcard
rm 29
# 28 thru 23 are reserved
rm 28
rm 27
rm 26
rm 25
# rm recovery
rm 24
# rm misc
rm 23
# rm cache
rm 22
# rm persist
rm 21
# rm data/emmc
rm 20
# now, re-create partitions but data is bigger
mkpart primary 1325 5421
name 20 userdata
mkpart primary 5421 5430
name 21 persist
mkpart primary 5430 5967
name 22 cache
mkpart primary 5967 5968
name 23 misc
mkpart primary 5968 5979
name 24 recovery
mkpart primary 5979 6012
name 25 reserve1
mkpart primary 6012 6019
name 26 reserve2
mkpart primary 6019 6028
name 27 reserve3
mkpart primary 6028 6062
name 28 reserve4
mkpart primary 6062MB 100%
name 29 sdcard
# exit parted shell
q
Let's create a file system on the partitions that require one. Note that I am formatting the SDCard using VFAT as, yes, EXT4 is a better FS, but it is also incompatible with Oppo's ROM and some apps may not require the proper permissions etc.
Code:
# Notes:
# -m 0: no reserved blocks
# -c 0: no max mount count
# -C -1: no mount count
# -i -1: max_int interval between checks
mke2fs -t ext4 -m 0 -L userdata /dev/block/mmcblk0p20
tune2fs -c 0 -i -1 -C -1 /dev/block/mmcblk0p20
mke2fs -t ext4 -m 0 -L persist /dev/block/mmcblk0p21
tune2fs -c 0 -i -1 -C -1 /dev/block/mmcblk0p21
mke2fs -t ext4 -m 0 -L cache /dev/block/mmcblk0p22
tune2fs -c 0 -i -1 -C -1 /dev/block/mmcblk0p22
# Hey look it’s an ext4 SDCard!
mke2fs -t ext4 -m 0 -L sdcard /dev/block/mmcblk0p29
tune2fs -c 0 -i -1 -C -1 /dev/block/mmcblk0p29
# Actually to avoid errors like unable to write to root of sdcard:
mkdosfs -n sdcard -F 32 /dev/block/mmcblk0p29
mount -t vfat /dev/block/mmcblk0p29 /sdcard
At this point, we have clobbered the /persist partition and this could cause issues as mentioned earlier. Let's restore it.
Code:
# Restore /persist partition
mount -t ext4 /dev/block/mmcblk0p29 /sdcard
# On computer
adb push mmcblk0p21_persist_ext4.img /sdcard/
# On phone
dd if=mmcblk0p21_persist_ext4.img of=/dev/block/mmcblk0p21
IMPORTANT! Flash your recovery partition now. If you wait until after rebooting, you will need to use fastboot instead.
Code:
# Recovery partition: on computer
adb push openrecovery-twrp-2.6.3.0-find5-TP-patch.img /sdcard/
# On phone
dd if=openrecovery-twrp-2.6.3.0-find5-TP-patch.img of=/dev/block/mmcblk0p24
Admire your work
Code:
parted /dev/block/mmcblk0 print
Reboot into your new recovery and install your favorite ROM

You should probably use the latest TWRP 2.6.3.1 found here: http://techerrata.com/file/twrp2/find5/openrecovery-twrp-2.6.3.1-find5.img
Looks good to me. Just be very carefully doing this.
Sent from my Find 5 using xda app-developers app
gdisk -b /sdcard/gpt.bin /dev/block/mmcblk0
those commands need to be typed in recovery even that one ?
Yes although I imagine this particular command should also work when booting system.

This thread is fine the only problem here is with those 2 binaries: mke2fs and tune2fs
You don't need to push them or chmod them since they are already in the recovery
Except that that thread is perfect.
Since we're at toying with partition, can't we merge the partitions in some way ?
Just wondering is there any way to build a script to do this in an automated way thus avoiding user errors and typos?
There is a thread on the oppo forums
http://www.oppoforums.com/threads/guide-resizing-internal-storage-on-find-5-32gb.8361/
Hello everyone,
is the guide for the 32 or 16 gb model?
I have 16 gb Oppo find 5.
Thanks.
PS: what "on your phone" is supposed to mean"?

If you don't know what does that mean don't do it you'll screw your phone.
hi
Please would you make something like this for oppo find 7a x9006?
thanks
Anyone willing to recompute all the offsets dor just one 16gb partition?

Hi all, I am trying to do this mod and I am half way through it with a problem
I am stuck on the new file system, I cannot use mke2fs or tune2fs, i get
Code:
mke2fs: not found
like it doesn't even exist, but it does I can see it. I get the same error for tune2fs. but parted and gdisk work fine.
Yes I did push them and chmod 755 them.. and I have tried running it from the /sbin directory.
Help!
Hello!
I'm getting the same error over and over again creating /dev/block/mmcblk0p21 to /dev/block/mmcblk0p22:
tune2fs -c 0 -i -1 -C -1 /dev/block/mmcblk0p21
"Bad magic number in super-block while trying to open /dev/block/mmcblk0p21"
"Couldn't find valid filesystem superblock"
So i can't create a file system on the created partitions. I have been looking everywhere for an answer. Somebody have an idea?
U should just wait. Andrew dodd found a way to make find7a have unified partition and he claims he can make it work on find5 as well. Let's give him a bit to figure it out tho.

Gdisk not working...
Ok guys sort of a noob here... Firstly, totally appreciate what you guys are doing here... I wants it bad, thass why i'm here.
So far... I have i have done...
"adb reboot recovery"
"adb push gdisk /sbin"
I figured that's how you are supposed to install it ... hope i'm not wrong, but i guess it pushed through fine
But after rebooting to system in TWRP , i opened terminal emulator and when i use the command
"gdisk -b /sdcard/gpt.bin /dev/block/mmcblk0"
I get ...
"/system/bin/sh: gdisk: not found"
now i'm too scared to proceed without backing up the partition tables... so please help...
edit - FYI , i'm running the last build of Asylum Carbon... should i just go back to latest oopo stable stock rom and then root my device again and then try all this again... would that help... ???
Directly from Andrew Dodds g+ " IT HAS BEGUN.
The first phase of Find 7a/7s LVM testing is here.* See linked post for details.* (Sorry to disappoint, but the first phase is "make sure we don't break existing configurations")
Once this phase is complete, the remaining list is:
Fix up the remaining TWRP issues (make RECOVERY_SDCARD_ON_DATA runtime instead of compile-time)

Does this work for the 16gb model?
Can someone help please?
I'm trying to do this, but after enter in parted [parted /dev/block/mmcblk0] when i try to do "rm 29", i get "can't remove 29: no such file or directory
I'm doing the "on your phone" commands in TWRP command line., is that correct?
I'm running stable colorOS 1.0.9i
Finally I finish the process.
My notes:
Goal:
Keep my current system intact (stable colorOS 1.0.9i , because i have no patience to format, install a new ROM and reinstall/recofigure everything
So I backup everything on phone with TWRP and I push sdcard content (wich include the system backup i made) with ADB
1 - If I push mke2fs and tune2fs IT WILL NOT WORK. I flash the last find 5 recovery (openrecovery-twrp-2.8.1.0-find5.img) and I dont push or chmod anyting, parted, mke2fs, tune2fs are all already in the recover and that's the only way I could run mke2fs and tune2fs
edit: 1.5 - The phone commands had to be enter via ADB shell. In TWRP command line, after you enter in parted it will not accept commands.
2 - To "rm 29", i had to "umount /dev/block/mmcblk0", otherwise "rm 29" fail due to partition in use
3 - after this instruction:
mount -t vfat /dev/block/mmcblk0p29 /sdcard
(the last one on the 4 block of code)
We have this:
# Restore /persist partition
mount -t ext4 /dev/block/mmcblk0p29 /sdcard
This instruction was the only one that give me a error, so I move to the next ones.
The error was that the partition was busy, what makes senses because in the last instruction we mount the same partition on the same folder but with different file system!!??
So I move to the next instruction. I have no idea if it's a instructions mistake but it looks like, because it says "# Restore /persist partition" but the command has nothing to do with /persist
4 - FINISH
5 - Reboot in recovery. Push sdcard backup to /sdcard. restore system backup with TWRP restore
Voila, my phone exactly as before but with 3,76GB for APPS. Finally!!! The "running out of space" message on a flagship quad-core 2GB RAM phone!!!!!!?????? Was driving me CRAZYYYYY
Thanks Fickx for the up to date information, I just did my re-partition successfully, here's what I did:
- Use Rashr update the recovery to twrp-2.8.1.0
- reboot into recovery
- connect to PC (Make sure adb works, "adb devices")
- on PC:
> adb shell
> umount /cache
> umount /sdcard
> umount /emmc
> umount /data
> umount /dev/block/mmcblk0p29
> parted /dev/block/mmcblk0
> rm 29
>...
> rm 20
> mkpart primary 1325 5421
> name 20 userdata
> ...
> name 29 sdcard
> q
> mke2fs ...
> ...
> mount -t -vfat /dev/block/mmcblk0p29 /sdcard
Open another PC command terminal
> adb push mmcblk0p21_persist_ext4.img /sdcard/
> adb push openrecovery-twrp-2.8.1.0-find5.img /sdcard/
Back to original terminal in "adb shell".
> dd if=/sdcard/mmcblk0p21_persist_ext4.img of=/dev/block/mmcblk0p21
> dd if=/sdcard/openrecovery-twrp-2.8.1.0-find5.img of=/dev/block/mmcblk0p24
> exit
> adb reboot recovery
Flash the rom.

2 questions
Is this Hack [suficient] safe, or should I wait for LVM?
If i do a full backup of my current system (colorOS 1.0.9i Stable) and after the hack, restore the ROM, will my phone be exactly the same than before but with 4GB for apps?
Thanks for the great work
LVM needs ALOT of work right now :/
I'm trying to do this, but after enter in parted [parted /dev/block/mmcblk0] when i try to do "rm 29", i get "can't remove 29: no such file or directory
I'm doing the "on your phone" commands in TWRP command line., is that correct?
I'm running stable colorOS 1.0.9i
Guys, After I exit parted shell, I can't execute mke2fs/tune2fs commands! I get:
/sbin/sh: mke2fs: not found
though I can find them (mke2fs and tune2fs) inside /sbin/ after I cd into it!
How can I solve this ?
Edit:
Solved ... I just rebooted into recovery again.
I did it It works hehehe
Thank you very much for this amazing instructions.
I had some difficulties while executing some of the instructions, but I did some search and tried unplugging then plugging the cable or rebooting into recovery again when the shell was giving me a hard time, and everything is back as it was except now I have 4GB internal storage !!
Does this have to be done while the phone is running ColorOS? I started the procedure on my 16GB phone, running CM11, but didn't get too far.
There is no /sbin. Found tune2fs and mke2fs in /system/bin. No parted there.
From PC over USB, copied parted to Download directory.
On phone, opened a Terminal, then 'su root'.
Remounted /system/bin rw: 'mount -o rw,remount /dev/block/platform/msm_sdcc.1/by-name/system /system'
Copied parted from Download to system/bin.
chmod 755 /system/bin/parted
Most of the umount commands fail.
Started 'parted /dev/block/mmcblk0'
Fails on first 'rm 29' because it is not unmounted.
I gave up there.
Interesting, automated repartioning:
www <dot> youtube <dot> com / watch?v=2CoTIojZGlI
Shame it doesn't have a 4GB option.
@Redfoox (in dev thread), did you push mke2fs and tune2fs at the beginning of the procedure or did you use the ones already included in TWRP?
I got this error?
Code:
/sbin # mke2fs -t ext4 -m 0 -L userdata /dev/block/mmcblk0p20
/sbin/sh: mke2fs: not found
The command also does not work in TWRP!
Anyone any idea what I should do now?

I did push the mke2fs and tune2fs at the beginning. Probably shouldn't have done that?
I have to wait each post for 4 minutes to post a new one
I've tried doing that during my second attempt, but got stuck at exactly the same point.
The fact that it shows mke2fs: not found tells me that you have both pushed it and CHModded it.
Push the files again, this time don't CHMod them and try it from the TWRP Terminal Emulator (from ADB shell just gives you permission denied but I didn't try it from TWRP that time).
If that doesn't work try CHModding them from TWRP. If that also doesn't work I'm out of a clue. All you could do at that point is use the last resort method (saved my device 2 times) and try the procedure again without pushing the files first.
Tried it and it gives the same errors. Cannot even chmod it through the terminal emulator.
I will go for the last resort method than
Too bad. Alright, feel free to ask questions if you run into trouble when you try again.
It worked i have 4GB now!
The only thing now is that my wifi does not work and I did do the following:
Code:
# Restore /persist partition
mount -t ext4 /dev/block/mmcblk0p29 /sdcard
# On computer
adb push mmcblk0p21_persist_ext4.img /sdcard/
# On phone
dd if=mmcblk0p21_persist_ext4.img of=/dev/block/mmcblk0p21
output of terminal:
Code:
/sdcard # dd if=mmcblk0p21_persist_ext4.img of=/dev/block/mmcblk0p21
16384+0 records in
16384+0 records out
8388608 bytes (8.0MB) copied, 3.260498 seconds, 2.5MB/s
Any idea how to restore this? I even redid this step without succes.

Got it working now. I had tot install modem 4.2.
Nice, enjoy the 4 GB!
Please help guys this is turning out to be a really frustrating experience...T___T
How are you guys even pulling this off... T___T
My adb works when the phone is booted but after "adb reboot recovery" and once in TWRP it cant see the device... and hence i cant proceed with the commands in Adb shell when the phone is connected and in twrp. i am running Liquidsmooth rom but i went back to the original rom to try this.
I'm able to execute
" chmod 755 /sbin/parted /sbin/mke2fs /sbin/tune2fs
umount /cache
umount /sdcard"
But not these ...
"umount /emmc
umount /data"
It says file or Directory not found.
then when i enter parted with the next command "parted /dev/block/mmcblk0"
I enter into parted, but cant see any of the following
"# rm sdcard
rm 29
# 28 thru 23 are reserved
rm 28
rm 27
rm 26
rm 25
# rm recovery

# rm persist

Now i'm totally clueless on how to proceed further... Would appreciate if you guys can shed a bit more clarity... This is really turning out to be a frustrating experience. Please guys...
Going back to Liquidsmooth to use my phone ... will again reinstall original os tomorrow and try again. :crying:
OK, so I got TWRP running sweet and now following the improved descriptions in main thread post #34.
Got stuck here, all before has been ok:
mke2fs -t ext4 -m 0 -L persist /dev/block/mmcblk0p21
Message back is:
Could not stat /dev/block/mmcblk0p21 --- no such file or directory
The device apparently does not exist; did you specify it correctly?
Now what?
EDIT - think I have it sorted. I didn't scroll down enough in the post #34 windows and missed some 'parted' commands!
EDIT - 'adb shell' had quit, and it wouldn't connect again. Tried to reboot TWRP to recovery, but it didn't recover, now stuck at Oppo text logo, can't connect by adb, doesn't respond to power button. Bricked.
EDIT - was able to access the phone by fastboot only, not adb. Flashed TWRP recovery again, it rebooted and took quite a while, now it is stuck at the cyanogenmod 12 boot up spinning arrow for 10+ minutes, maybe it will recover eventually. If not, I'll try to reflash CM12 too.
Hello
Today was the third try to get this thing working ^^
But somehow i cant get past the first command.
Every time i try to unmount things like /cache or /dev umount only returns "invalid argument.
I never pushed the files from the zip. TWRP 2.8.3.0 is used.
I tried to attach a screenshot to help, but im too new to do that -.-
Thanks in advance
