PIT file method to revive your phone from a MMC_CAP_ERASE brick

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

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.

this was the partition scheme before implementing the workaround:

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:

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...

WoooooooOOOOOOoooooooowwwww!!!!
YeeeeeeEEEEEEaaaaaAAAAAaaaahhhhhh!!!!!!
You are the man, bro.

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:

Lost A LOT of storage after installing a new rom

Hi everyone, this is my first thread
I recently rooted my 16gb WiFi only nexus 7. After installing 3 different roms (touchwiz, cyanogenmod 10, and xenon HD) I didn't like touch wiz or cyanogenmod, and I'm currently running xenon HD. However, when I opened my storage today, of said I had 3.6gb remaining. I thought it may have been all the apps, so I factory reset it, reset the partition, and deleted all data via recovery mode. That gave me about 1 more gigabyte. I opened ES file explorer and deleted everything there. I still have only 4.6 gigabytes usable. Anyone else have this issue?
Thanks

Well, I deleted some old backups and now I have 7.5 gb of storage, which should do for now. But I still have that 6 GB leftover, anyone know whats wrong?
Thanks

OK. Now I mucked around in the mounting/unmounting stuff, and now it won't boot. It's stuck at the Google screen. Someone help please???

You are not the only person who has experienced this.
Bottom line is you need to rebuild the /data filesystem, which necessitates getting everything off of it including any nandroid backups plus anything worth saving in /sdcard
Either the "format data" option in TWRP, or using fastboot.
Code:
fastboot erase userdata
fastboot format userdata
I've had the latter create short file systems - and also not create short file systems.
Whatever causes this it seems to depend on prior state in the filesystem, even though I don't think things should behave this way. I've also had TWRP's "Format data" menu option create new, empty, & corrupted ext4 file systems. Ugh - I hope your luck is better than mine.
Note that you can run "df -k /data" in the recovery (after you have created the new filesystem by either method) to find out how big it is; better to check things are OK right away, rather than after you've put effort into restoring things or flashing ROMs.
Long boring thread, but related.

Wait, is that for getting back the storage or actually letting it boot up? Because right now the storage is the least of my concerns.

What I described is for getting back lost space (by recreating from scratch the ext4 filesystem in the userdata partition).
As it doesn't touch either the boot partition or the system partition, your tablet should certainly be able to boot. If you don't do a restore of /data from a backup, the result will be like a factory reset of whatever rom you had on the tablet.
Just make sure to check the size of the data partition before you start re-customizing or restoring data from backups to make sure that you got the full size of the partition.

If you screwed around with your system partition and it wouldn't boot before, then with a freshly formated and empty /data filesystem, of course it still will not boot. The instructions I provided in this thread only involved the userdata partition!
But you didn't say "I did such and such and it still hangs during the initial boot phase where the X logo is flashing on the screen"; instead you said:
"Ughhh its still not turning on".
WTF? Has your problem now morphed into a dead battery problem, or is the language you are using just incredibly imprecise?
Anyway, Flash a new ROM using the custom recovery. Any ROM - you pick. Maybe not that Xenon ROM or whatever it is called. See if the new ROM boots. And then immediately after it boots, check to see what size the /data partition is.
And if you come back into this thread anymore please be specific about what you are attempting and exactly what symptoms you are observing.

ADB is available in the custom recovery... so long as you have the right drivers installed on your PC. And that is NOT controlled by some setting in the most recent ROM that you flashed - it is always running in the custom recovery.
One of the quirks about ADB in the recovery with the Nexus7 is that it claims a different USB address than "ADB Composite Interface" that the regular OS does. This might mean that ADB works correctly with the regular OS booted, but not when the custom recovery is booted, depending on what drivers you have installed. Yes, you need yet another driver installed even though they are both "ADB" connections. But that is a Windows driver issue, not a problem with the N7.
You can also use an OTG cable and a USB drive with TWRP if that is easier. Put your ROM on the memory stick and then use TWRP's "external memory". To be most compatible, make sure the USB stick is formatted in a FAT format. (I don't know if TWRP can handle NTFS).

The ADB daemon - "adbd" is definitely sitting there running inside the custom recovery. Even if you can't communicate with it because of a lack of a driver, you should nevertheless be able to see it as an unknown device in the PC's device manager.
I have done the same hack - hand editing the .INF file - with both the Google SDK drivers and the Asus drivers, and in both cases it worked fine (one driver for everything: ADB in the OS, ADB in TWRP/CWM, and fastboot with the bootloader).
I have also used the Google SDK driver without modification plus the XDA Universal Naked driver. That means using the Google driver for fastboot and ADB when the OS is booted, and the XUN driver for custom recoveries only.
At the present time the ONLY driver I have installed is a hacked version of the Asus drivers.
Win 7 complains about signing when doing this (for the Asus drivers for sure, I can't remember if the Google driver is signed or not).
As I mentioned, Win 7 Pro x64. I suppose the whole "violated signing" might make life even more difficult with Win 8 though.

bftb0, did you personally experience the problem of losing space on the internal memory? I tried your advice, but it didn't work. I'm on PAC(man) ROM. I booted into TWRP, did the data wipe (not factory reset, the full wipe that wipes the everything) but I still only have 13 gb available (on my 32 gb Nexus 7). I rebooted into TWRP and did a factory reset AND wipe data, but I am still missing half of my internal memory.
Do you need to do this on the stock ROM for it to work? Any other tips would be greatly appreciated.

Yes, it really did happen to me.
After it happened I took the trouble to download 4 different versions of TWRP (2.4.1.0-2.4.4.0), and I re-created the ext4 filesystem with:
- each of the different versions of TWRP and
- fastboot format userdata
after each, I did a "e2fsck -f -n <block-device>" on the (unmounted) userdata partition to see that they were clean, and I also dumped the output of "tune2fs -l <block-device>" to a file for comparison. Other than things that I would expect to be different (e.g. partition UUID identifier strings and timestamps), I noticed no differences. And also, I couldn't reproduce the problem for the life of me.
Above you mention full "data wipe". In TWRP (v2.4.1.0), this is presented as a separate button in the "Wipe" sub-menu where it (the last button in the first column) is labeled "Format Data". I suppose this is what you mean, but thought I would be explicit to avoid any confusion. (The "factory reset" procedure in the two custom recoveries - both CWM and TWRP - can not possibly re-create the ext4 filesystem in /data, as the /data/media/0 SD card files are in there. But the "Format Data" button does destroy & recreate the whole filesystem).
If you press on this button and at the same time capture the output of the "ps" command, you will see that TWRP recovery invokes the /sbin/make_ext4fs in the following way
Code:
make_ext4fs -l -32768 /dev/block/mmcblk0p<PARTNUM>
(CWM probably uses a different external command as it does not seem to have a "make_ext4fs" command in it's ramdisk. Probably mke2fs with ext4 options on the command line)
Anyways, I can't say I have my finger on exactly how to resolve the problem as I can not re-created it. But it did happen to me.
One thing you can try rather than using TWRP's "make_ext4fs" command (underneath that button "Format Data") is to reboot into the bootloader from TWRP, and do the file system formatting in fastboot instead of TWRP, as in:
Code:
fastboot format userdata
(noobs: caution, this is a full userdata wipe)
and then bop back into the recovery and check things with "tune2fs" report
Code:
tune2fs -l /dev/block/mmcblk0p<PARTNUM>
My 32G N7 shows a total block count of 7503608 (x 4k/block = 29.3 GiB) doing this.
As I mentioned before, it's a good idea to check to see you have the right size before you start restoring stuff to avoid wasting time. You can do it above with "tune2fs -l", or because TWRP seems to want to mount /data and /sdcard when it boots, just run
adb shell df -k /data
to get a report of total and used size.
Sorry this isn't more definiitve. I would have spent more time looking at this, but it is tedious as you need to unload the whole d*mn SD card in order to experiment. Thank goodness my 30GB partition only has about 10Gigs of stuff on it.
good luck

I'm a total command prompt beginner here, so could you explain where I'm doing the fastboot format command? In a terminal on the device? Using adb on my windows machine? I tried all that I could think of, but none of it worked. No form of wiping the device (yes, via "format data" in TWRP) seems to work. I'm still missing half of my storage.
EDIT: Okay, so I ran the command--I had to have the device in the bootloader, duh. Unfortunately, it still did not work. When recreating the file system, it said there was a total of ~3.5 million blocks--half what I saw reported in the other thread. Not surprising, since I'm missing half of my storage. How come this is working for other people but not me? I tried doing both at the same time, but to no avail. This is getting stupid.

Arrgh. Did you do the "fastboot erase userdata" first?
Here's what the fastboot format looked like on my device when I did this last (3/13):
Code:
$ fastboot erase userdata
******** Did you mean to fastboot format this partition?
erasing 'userdata'...
OKAY [ 4.974s]
finished. total time: 4.979s
$ fastboot format userdata
erasing 'userdata'...
OKAY [ 4.454s]
formatting 'userdata' partition...
Creating filesystem with parameters:
Size: 30734811136
Block size: 4096
Blocks per group: 32768
Inodes per group: 8192
Inode size: 256
Journal blocks: 32768
Label:
Blocks: 7503616
Block groups: 229
Reserved block group size: 1024
Created filesystem with 11/1875968 inodes and 161774/7503616 blocks
sending 'userdata' (139197 KB)...
writing 'userdata'...
OKAY [ 33.733s]
finished. total time: 38.194s
As I said, I was unable to reproduce the problem even though I tried. But it almost seems like the creation of the new filesystem is inferring something from somewhere (but where?) about the userdata partition size which is incorrect. Almost like it happens because of something it sees in the prior filesystem (which is being destroyed). So it becomes irreproducible unless you can recreate the same starting condition.
There's other mysterious crap going on here too. See the output above? The part where it says "sending 'userdata' (139197 KB)" ? It will say this no matter where you run the command from, and there is no 139 MB "userdata.img" file in the folder it runs from!!! 139 MB? For a filesystem which is empty when you mount it?
I don't know. Here's one more thing to try, though. In addition to doing the "erase" & "format" commands, perhaps you could actually flash the userdata image from the stock ROM
Code:
fastboot erase userdata
fastboot format userdata
fastboot flash userdata userdata.img
and then when you boot to the custom recovery, perform a "factory reset" - or try doing the "Format Data" thing in TWRP after (or before?) the above steps.
If none of this works, I suppose you could try the equivalent sorts of things with CWM and see if you get a different result.
You don't need to permanently install CWM with a hard flash - you can just soft-boot it for a single session:
Code:
fastboot boot recovery-clockwork-touch-6.0.2.3-grouper.img
Sorry this is so vague, but you know how it goes - you stumble into a problem, start fooling around until it gets fixed - and because you weren't really expecting the problem in the first place, you haven't written down the exact conditions and steps. Like I said, I tried to re-create the problem a variety of ways - but failed at that effort.

This have two effects, as far as I know:
I can't install any Gapps greather than pico.
My apps seem to be installed in the system partition. Therefore, once it is full, the whole system gets broken.
I can't barely have apps without Trebuchet crashing in LineageOS or the app optimization failure in the stock ROM.
I have tried to increase the system partition manually by using parted and increasing the number of sectors:
System before: 1253376s to 2891775s
System after: 1253376s to 5963775s
But TWRP seems to detect the system partition always as 700MB, no matter the repartition that I have made.
I am wondering if you have ever been able to increase the system partition or if there is any room with a bigger one.
Thanks!

But TWRP seems to detect the system partition always as 700MB, no matter the repartition that I have made.
I am wondering if you have ever been able to increase the system partition or if there is any room with a bigger one.
Thanks!

You have to customize TWRP too as it is programmed for manta that has 700MB.

Cannot boot recovery partition failed
Hi everyone,
I have an issue,
Yesterday I tried to install LineageOS 16 and GappsPico
Since my Manta Nexus 10 only have space for 700M, I couldnt install any type of Gapps.
So I do a partition changed.
After deleting and recreating partition, I mistakenly reboot the linux kernel. So it means my Nexus doesnt have any TWRP or anything
Right now, if I pressed power + volume up - hoping to get the recovery option - which I dont get, I only got start.
Is theres a way to fix this? or its just doom for me?
really appreciate it

@tongqabiz This may help you: https://forum.xda-developers.com/showpost.php?p=77992510&postcount=3

Yes it's possible. YMMV.
I was able to grab some space from the userdata partition using this guide: https://forum.xda-developers.com/nexus-4/general/guide-increase-nexus-4s-partition-space-t3800264
This guide is for Nexus 4s, but was taken from other guides built for other Nexus devices, so I took a chance with my Nexus 10 manta. The guide explains how to take the space from the cache partition which also works, but i repeated the process to set the cache back to its default size, and take the space from the userdata partition instead. Now I'm able to flash LineageOS 16 and open-gapps pico. I have some display issues with icons disappearing, and I don't seem to be ale to set any wallpaper, but I've not seen anything else causing any problem (yet). I've rooted it using addonsu (specifically for LineageOS I think?) https://mirrorbits.lineageos.org/su/20190709/addonsu-16.0-arm-signed.zip, and installed remote desktop and busybox in order to run kali.
I had to repeat some steps in the guide where i got some odd error messages about device busy and stuff e.g. when running mke2fs on newly created partitions. Naturally, don't expect to keep any data on your device if you follow this guide, and also expect to brick your device if you're careless with entering the commands.

Hi,
After checking my Nexus, I have noticed that my system partition is quite small:
This have two effects, as far as I know:
I can't install any Gapps greather than pico.
My apps seem to be installed in the system partition. Therefore, once it is full, the whole system gets broken.
I can't barely have apps without Trebuchet crashing in LineageOS or the app optimization failure in the stock ROM.
I have tried to increase the system partition manually by using parted and increasing the number of sectors:
System before: 1253376s to 2891775s
System after: 1253376s to 5963775s
But TWRP seems to detect the system partition always as 700MB, no matter the repartition that I have made.

Hi,
I thought there was a TWRP Special image written for SELinux (TWRP-3.1.1-0-manta.img MD5: 4290afd6b1697d7f7b0d958131010676) written specifically for N10 to address this issue.
It is not the one from the TWRP site tough. Not sure where i got it from either. Check for the above checksum once you find it. I guess can't post any URL's or upload anything atm.
Cheers :fingers-crossed:

[TOOL][UNOFFICIAL][PORT] REPIT: for Nexus 7 (2013) [deb][flo]

This is a port of Lanchon REPIT.
- Nexus 7 (2013) Deb (LTE) and Flo (WiFi) -​
Disclaimer:
I am not responsible for your actions or consequences, directly or indirectly, related to the files and/or advice offered.
It is your choice to proceed.
What is REPIT?
REPIT is a simple, safe, device-only, data-sparing, and easily portable repartitioning tool for Android devices.
See the GitHub README for more on What REPIT is. GitHub - Link
Limitations:
Requires TWRP (or TWRP based) recovery.
Does not support encrypted devices.
Will cause data loss if the repartitioning process is externally interrupted.
See the GitHub README for more on Limitations. GitHub - Link
---
Notes:
A few years ago (September 2018), I made a port of REPIT for deb,flo and manta that was spread out between multiple threads.
Some comments and instructions were lost in thread chatter or just in a different thread altogether.
The file name actually configures the repit script.
Noted that you may have to toggle MTP Disable, Enable, Disable.
Noted that you may have to reboot into TWRP after disabling MTP.
Remember /tmp is wiped after a reboot. Copy repit to /sdcard and after rebooting back into TWRP, copy it from /sdcard to /tmp using TWRP File manager.
Noted that you may have to unmount cache and data.
Do NOT flash repit from USB/OTG.
This is designed for a stock partition layout. If your device has been modified and a vendor partition was created, REPIT will not work.
Side note:
Lanchon added Nexus 7 (2013) to the official list. (November 2019)

Be Careful.
There are always risks involved when you start messing around with a device.
If something goes wrong, you may end up with a non-working "bricked" device.
This is especially true when you start modifying partitions.
Backup what you want to save and store it off device.
Copy it to your computer, cloud storage, USB, ...
Instructions:
This operation might take a long time and must not be interrupted.
- Depending on the device and REPIT configuration, this might take a few hours.
Make sure your battery is fully charged or mostly charged.
- You can connect to a charger while the REPIT script is running. May or may not charge depending on the recovery.
How To:
If you already have a ROM installed, repit will backup, change the partition, restore and resize.
- You can just reboot once the script finishes.
Boot into TWRP
Swipe to Allow Modifications
Copy the repit zip to /tmp
Disconnect from computer
Disable MTP
Disable MTP TWRP -> Mount
Install repit
TWRP -> Install -> navigate to /tmp and flash the repit zip
Reboot to system
If you are doing a clean install, add the +wipe option to system in the zip file name. This will speed up the partitioning since system will not be backed up and restored.
lanchon-repit-20210220-system=max+wipe-cache=16M+wipe-flo.zip
- Reboot back into TWRP after the script finishes.
- Then follow the instructions from the rom thread to install the rom you are going to use.

Note about configuration.
The user configuration is done by renaming the zip file before flashing it.
Not much room to change on deb/flo.
The modifiable partitions are only system and cache (22 and 23).
The actual partitioning is done by a sector range. This is declared inside the script along with a default configuration.
Code:
# the set of partitions that can be modified by REPIT:
# <gpt-number> <gpt-name> <friendly-name> <conf-defaults> <crypto-footer>
initPartition 22 system system "same keep ext4" 0
initPartition 23 cache cache "same keep ext4" 0
initPartition 24 misc misc "same keep raw" 0
# the set of modifiable partitions that can be configured by the user (overriding <conf-defaults>):
configurablePartitions="$(seq 22 23)"
...
# the set of contiguous partitions that form this heap, in order of ascending partition start address:
heapPartitions="$(seq 22 24)"
# the disk area (as a sector range) to use for the heap partitions:
heapStart=$(parOldEnd 21) # one sector past the end of tzb.
heapEnd=$(parOldStart 25) # the start of recovery.
By default, REPIT will back up, restore, compress and/or expand a partition.
The +wipe option will wipe the partition.
The max option is an easy way to allocate the remaining space for a partition.
The misc partition is not part of the user-config but, it is in the sector range.
It will be moved to the the end of the sector range without alteration.
The default zip name lanchon-repit-20210221-system=max-cache=16M+wipe-flo.zip
Creates a 16M clean cache partition. (Wiped)
Uses the rest of the unallocated space in the range for system.
System is backed up and restored since the +wipe option was NOT added to system.
Since only system and cache can be configured, this only allows a few options for deb and flo.
Default zip name. -system=max-cache=16M+wipe-
Include wipe system. -system=max+wipe-cache=16M+wipe-
See the GitHub README for more on how to configure. GitHub - Link
Cheers all.

<RESERVE>

I think this deserves a bump, because, this is some great work right here for those wanting to stick with a stock-like partition layout!

Hi, I want to go back stock partition size. So i have to rename the zip.
What zip name?

Problem fixed. Now 19.1, pico gapps and Magisk 25.0 were flashed in success. The problem was that I didn't follow through the steps carefully described on the OP to increase the partition sizes as follows:
The file name actually configures the repit script.
Noted that you may have to toggle MTP Disable, Enable, Disable.
Noted that you may have to reboot into TWRP after disabling MTP.
Remember /tmp is wiped after a reboot. Copy repit to /sdcard and after rebooting back into TWRP, copy it from /sdcard to /tmp using TWRP File manager.

Edit: NVM, i used restock to start fresh, and it all went fine. I've had this table kicking around long enough that I'm sure something was done that sysrepartundo couldn;'t undo.
How did you actually fix it? I ran sysrepartundo, am running it from the tmp folder with mtp disabled and nothing mounted, and still getting error 1. I've double check, all my partition sizes are stock.. I've been at this a few hours now and am getting frustrated.

sysrepartundo is ancient and useless nowadays, try sysrepart-stock instead

Thank you for the script. I was able to repartion my flo and make it compatible with android 12L. Everything went smooth after realising (and correcting this mistake) that i"ve been putting the .zip inside /sdcard/tmp instead of /tmp (I was getting error 1 in TWRP).
During instalation process i"ve connected flo to charger and it indeed charged during repartition process
Things i"ve noticed
- TWRP appeared to be very laggy during repit process and took several seconds to reconginse the charger (to show to + sign next to the battery % to be precise)
- after device rebooted to stock 6.0.1, MTP didn"t work correctly. It appeared in my computer as "Nexus 7", but was completely empty. One more reboot (this time got short loading toast of "android is updating") and internal memory was visible from computer again

THANKS! It worked great for me also. I have mentioned it in the [GUIDE/TUTORIAL/HOWTO] Google Nexus 7 2013 Stock to Android 12 Tutorial.

Hi,
I had used @followmsi's sysrepart_1280_120.zip some time ago.
Now I'm interested in @followmsi's lineage 19.1 and want to use your lanchon-repit-20210221 script for increasing the system partition again.
Would you still consider the partition layout as stock, so I could use your script ? (See attachments)
And do I need a PC as the USB port is inoperative, so no way to connect to a PC?
Thank you very much in advance!

You should be good to go.
Using one of the older (re)partitioning methods did not affect the partition table too much.
The note about a stock partition layout is mainly for users who used a (re)partition script that adds a separate vendor partition.
Cheers.

Would you recommend any precautions like putting files like restock on my device before running your script as I cannot connect to PC?
Thanks a lot for your help!

hi, i need some help, after using this script i can't seem to install any rom, i just can't format or mount any of my partitions, and sideload stops at some random %, anything i can do to restore? i backed up all files advised.

Hello, i'm having trouble installing Android 12L on my Nexus 7. I simply cannot get lanchon-repit to flash. It wont work, no matter how often I follow the steps and how thorougly I follow the guide. I tried everything. Already restored to "fabric-partitions" so on and so forth.
I'm constantly getting Error 1. I'm slowly losing my mind here.
Kind regards hoping for an answer
septchy
edit: also constantly says partition #30 not found.

I'm getting the following errors on flo:
Code:
FATAL: partition #31 unexpected
[ERROR 1]
Any ideas? Thanks

mkpart physical ext4 3655361s 4441793s
Code:
mkpart physical ext4 4441794s 61054722s
Code:
mkpart physical ext4 61054723s 61071326s
Code:
name 21 system
Code:
name 22 cache
Code:
name 23 userdata
Code:
name 24 storage
Code:
quit
Code:
sync
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

Or just use partition unified by M1cha script here https://github.com/M1cha/aries-image-builder
Installation:
Backup all your data(including internal sdcard, and EFS just to be safe)
if you don't use the custom Bootloader yet, flash this package using flash_core.bat/sh first. See the big red warning above for more information
flash the package using flash_partition_table_and_core.bat/sh
boot into recovery(which is TWRP now), recreate the filesystems for all partitions(system,data,cache,sdcard to ext4) in the wipe menu and reinstall your ROM.

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

Hi, I have a problem. I don't have partition 24 (storage).
Mi 2S (MIUI V9.2.2.0)

I installed ROM (skipped steps with partition 24) and it works just fine.

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

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,

TWRP boots OK ?

Thanks! Works like a charm
