[SOLVED] How to restore damaged Internal SD card partition layout? Tried everything.

I did something really bad to my INTERNAL SD CARD partition layout, so now I have
I have the i8190N model

Warning: /dev/block/mmcblk0 contains GPT signatures, indicating that it has a
GPT table. However, it does not have a valid fake msdos partition table, as it
should. Perhaps it was corrupted -- possibly by a program that doesn't
understand GPT partition tables. Or perhaps you deleted the GPT table, and are
now using an msdos partition table. Is this a GPT partition table?
Yes/No?
As you can see, there is no /system, /cache and other stuff, that should be there.
My ClockWorkMod recovery tool can't mount anything (/cache, /system, nothing)
I really did everything I could. I tried: restore from backup (I have one, made with recovery tool), install new ROM (With recovery tool), install stock firmware and stock kernel in ODIN mode. I even tried some PIT file: nothing did absolutely nothing to my status.
Frankly I miss some important part in understanding of filesystem, partitions, images, what is ROM, what is stock kernel etc ...
What should I do?
UPDATE:
Short answer: user right PIT file and burn it with Odin3. Long answer in post below.

Found interesting file:
Code:
~ # tail ./etc/recovery.fstab

Have you tried to flash stock firmware again with re partition ticked and the pit file? Using the pit file make sense only if you flash the whole firmware with it

To be honest, I've never seen a problem like that. In Odin there's an option to erase all nand. I don't know if this would help you, since you should have an efs backup and I don't know if it will bring consequences.

Try firmware posted here, with pit-file.
It's worth a try. It has saved me a few times, but from other problems.

Oh sorry. My mistake. I missed it was i8190N.
Sent through time and space from my s3mini/CM10.

Found it!
I found it!
The answer was in PIT file, because as it says here:
you will only need to use this if a firmware update needs to change your partition layout (very very unlikely) or if you mess up you partition table (you don’t want to do this)

Which is definitely my case.
So, I tried that GT-I8190N and GT-I8190 should be used with different PIT files (I tried to use for GT-I8190 one). So I found long list of PIT files here
Thank you everyone for help.

How I fixed my bricked Nexus 5 (corrupted userdata, bootlooping)

Hi everyone,
First of all - apologies if this is in the wrong forum. First time I post something, so not too sure if this is the right place.
I've been struggling with my Nexus 5 for the past 3 days after I attempted a factory reset. After trying everything I could find, I managed to combine some strategies from different threads, and got some help from a friend who is a linux specialist. As it has been REALLY HARD for me to fix this, I thought I would post the solution in case anyone is seeing the same issue.
Summary of my issue:
I attempted a factory reset to cleanup the phone. That was really all I intended to do.
The factory reset got stuck on "erasing". After 30 minutes waiting, I forced the phone to reboot. Then everything went downhill.
My Nexus 5 started bootlooping. It wouldn't even get in recovery mode.
I've flashed ClockWorkMod Recovery, and tried to format everything and start again. The processes to wipe partitions would fail.
Flashing stock also failed, as things would hang on "erasing cache".
I found references on multiple threads about things to try - from flashing other ROMs, to formatting the file system manually, and basically trying every step of a flashing a stock installation manually.
The bottom line is everything would hang because the system could not mount the /data partition.
When I tried to use "e2fsck" to check /userdata partition, it would give me an error about the file system being corrupted, and suggesting to use a different superblock.
Some threads here in XDA suggested to use CWM and TWRP to format the partition, as that would usually fix the problem. It didn't work in my case.
The system would basically hang when trying to format /data, with any method I tried.
When using the "dmesg" command, I would also see lots of errors with superblocks when trying to mount "/data".
I considered it could be a hardware issue, but I was not seeing problems with the other partitions (/cache, /system, /recovery, and so on).
Solution:
I fixed the problem by removing the partition, recreating it with "ext2" file system, then upgrading to "ext4" manually, and finally flashing the system images again WITHOUT flashing userdata.
Every time I flash "userdata", the partition just gets corrupted.
This is the step by step on how I did it:
1) Start the phone on bootloader by holding power button + volume down. Flash CWM recovery through fastboot.
Download CWM recovery from here: https://clockworkmod.com/rommanager
I'm using windows, so I opened a command prompt on the "Android SDK\platform-tools" folder.
run: "fastboot flash recovery <CWM_Recovery_Folder>\recovery-clockwork-6.0.4.5-hammerhead.img"
2) Reboot in recovery mode, so that it would load ADB. In the command prompt I ran "adb shell" so I could use the linux tools
Use "parted /dev/block/mmcblk0" to open the parted tool for the mmc block.
Use command "print" to list all partitions. You should see something like this:

3) Remove the existing data partition by running command "rm 28" .
4) Recreate the partition and the file system with "mkpartfs". I didn't use all parameters at once, but just informed the proper values as requested by the tool:
(parted) mkpartfs
mkpartfs
mkpartfs
Partition name? []? userdate
userdate
userdate
File system type? [ext2]? ext2

5) The partition should now be recreated as "ext2" file system. I've set the partition name with:
(parted) name 28 userdata
name 28 userdata
name 28 userdata
Click to expand...
Click to collapse
If you print again, you should see the new partition as ext2 file system:
(...)
28 2032MB 31.3GB 29.2GB ext2 userdata
(...)
Click to expand...
Click to collapse
6) Upgrade the FS from ext2 to ext4 by using make_ext4fs:
make_ext4fs -l 29236371456 -b 4096 -g 32768 -i 8192 -I 256 -j 32768 -L msdos -a /data /dev/block/mmcblk0p28
Now here is the interesting part. When I tried to run "flash-all" from the google stock image, this is what I would see when it ran the format script on the userdata partition:
OKAY [ 13.186s]
formatting 'userdata' partition...

When I manually ran the make_ext4fs, the only difference was I added a label "msdos" and this was the result:

Almost the same thing, but with a difference in "Inodes per group": stock script shows 8192, and running manually it shows 48.
I have no idea why is that. Honestly I know very little about linux and its file systems, so I don't know what that means.
After I did this, I was FINALLY able to mount the "/data" partition.
8) Checked the file system with e2fsck. It now worked fine:
~ # e2fsck /dev/block/mmcblk0p28
e2fsck /dev/block/mmcblk0p28
e2fsck 1.41.14 (22-Dec-2010)
msdos: clean, 11/10464 files, 45158/7137786 blocks
~ #
9) Manually flash google stock system, cache, boot, and bootloader.
I was using this image: hammerhead-ktu84p-factory-35ea0277.tgz
I uncompressed this to a folder, and also uncompressed the image-hammerhead-ktu84p.zip.
So I ran:
fastboot flash system system.img
fastboot flash cache cache.img
fastboot flash boot boot.img
After this, I rebooted the system and it loaded, after loooooong 3 days reading through everything I could on XDA!
These were some of the threads that helped me in one way or another to get to this solution:

I really hope no one else had the same "luck" as I did, since this problem has been a nightmare.
But in case you unfortunately do... hope this helps!

Great guide. Might become handy for other users. It should be stickied

Why would you force reboot while factory resetting in the first place lol
Sent from my Nexus 5

Good guide but a bricked phone is rendered useless, hence the name 'bricked.' If your phone can still power on, it is not bricked. You said your self you got it out of a bootloop. That's essentially all you had, a bootloop, and you were able to figure out what was wrong with it.
Just a heads up so we don't throw that term around loosely since a lot of people do so.
You can't bring a phone back from a brick. I think JTAG is an option but its for Samsung phones only. (Feel free to correct me if I'm wrong.)

Yeap, I know it sounds stupid but the factory reset was hanging, lol.
I tried multiple times and it would hang every time. I left it running for more than 3h once and nothing happened.

Thanks for clarifying! I thought bricked also meant "the phone is about to go useless, but there is a tiny hope", lol.
Is there a way to correct the thread name?
You're right - it was only bootlooping.

There's soft-brick and hard-brick.

dont know how it got bricked..in morning when i wake up its suddenly start showing the boot only for hours. I've tried flashig it.evertime got flash write failure for bootloader and other images except boot.img .i've checked for emmc its fine and showing the device partion.
I'm using nexus 5 16gb device.pls anyone help

I assume the bootloader is unlocked since you are able to flash the boot.img. Try this: re-lock the bootloader, reboot to fastboot and see if the bootloader remains locked. If the bootloader unlocks itself, this is an indication that the memory chip is damaged. Also try flashing the older stock ROM available.

Try the suggestion about relocking there bootloader and checking to see if it stays locked. If it doesn't stay locked, I would replace the motherboard.

When trying to delete partition 28, I get:
Error: Input/output error during write on /dev/block/mmcblk0
Anybody else got this and found a way to solve it?

audit13 said:
I assume the bootloader is unlocked since you are able to flash the boot.img. Try this: re-lock the bootloader, reboot to fastboot and see if the bootloader remains locked. If the bootloader unlocks itself, this is an indication that the memory chip is damaged. Also try flashing the older stock ROM available.

Thanks, I've been reading for quite some time looking for a solution to fix my Nexus 5 (I bought it brick just to fix it), and it does exactly what you mention here in your post. It recognize fastboot, it lock the bootloader but when the phone reboot, it display bootloader unlock. It doesn't let me flash the recovery img. by computer.
Thanks

The motherboard's flash memory is defective which means you'll need to replace the motherboard to have functional phone.

[HELP] What happened here? Hardbrick after partitioning?

My device: MotoX (ghost)
Hey guys,
Today i pushed "parted" to my /sbin, chmodded 0755 and removed/recreated my userdata partition removing 5mb of total.. (to try to solve a known encryption bug of CM). Then, i reboot.
Now MY PHONE LOOKS HARD BRICKED!
How it is possible? i just deleted/recreated the userdata partition,
yes parted create on format ext2, but the next step is to convert to ext4 > f2fs..
but my phone does not start!
Black screen
No fastboot
lsusb does not list the usb connection..
Pressing the ON = doesn't boot
Pressing vol down + power = doesn't boot
Inserting charger = doesn't boot
No Lights on.
Battery is ok (i think), i started working w/ 100%.

[Guide] Repartition Nexus5 to increase system partition - Space for Rom & Stock Gapps

[Guide] Repartition Nexus5 to increase system partition - Space for Rom & Stock Gapps
Before I begin...don't do this if you don't know what you're doing. If you know what you're doing still don't do this. This is dangerous, and in general people don't even make good guides for this likely because it's SUCH a stupid thing to do. Samsung phones support PIT re partitioning, but for something like a Nexus, there is no easy guide. You can and likely will brick your phone...at best you will certainly wipe all data.
I wanted to install a nougat rom on my cracked-screen Nexus5, but in flashing it AND stock gapps would error out since there isn't enough room on the /system partition for both. The Nexus5 comes with a 1GB system partition which was fine way back in the day, but isn't really fine anymore. In order to pull space from the large userdata partition, we need to do some linux trickery. I chose to make /system 2GB, which may be overkill, but this phone is going to be a baby monitor/white noise machine for a 5 month old so who cares.
The prerequisite for this process is a TWRP recovery, and that's pretty much it. Ideally, fdisk would be baked in with busybox or the parted utility would be on the phone and you could use the resize function...every time I tried to use busybox's fdisk led to errors or commands wouldn't work, and parted's resize command can't deal with ext4.
The high-level procedure here is, since filesystems must be contiguous and in order so they can be addressed properly, we need to delete every partition inclusively from system to userdata, then recreate them with new storage offsets. To visualize this, here's the storage layout as it started out on my Nexus 5:
Code:
Model: MMC SEM32G (sd/mmc)
Disk /dev/block/mmcblk0: 31.3GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags

22 191MB 192MB 524kB fsc
23 192MB 192MB 524kB ssd
24 192MB 193MB 524kB DDR
25 193MB 1267MB 1074MB ext4 system
26 1267MB 1298MB 31.5MB crypto
27 1298MB 2032MB 734MB ext4 cache
28 2032MB 31.3GB 29.2GB ext4 userdata
29 31.3GB 31.3GB 5632B grow
Looking at that, we want to increase system (partition 25), shift crypto (partition 26), shift cache (partition 27), and shrink userdata (partition 28). If you try this on a different phone, you'll have different partitions to move.
I did this from a Debian desktop using adb, but you can use any platform that has adb. You need to download the parted binary linked below, a nexus5 Nougat rom (or any rom I guess), and a gapps package (I chose stock). Here's the commands I used:
Code:
wget http://iwf1.com/iwf-repo/parted.rar
unrar e parted.rar
sudo adb push parted /
sudo adb shell
~ # chmod +x parted
~ # ./parted /dev/block/mmcblk0 p

~ # umount /sdcard

There were some logging errors with the SantoshM nougat rom I tried, but they had no impact. I am unmounting /sdcard and that's where it's trying to stash the logs, hence errors.
You can see that the offsets for the new partitions are 1024MB higher than the originals, meaning the partition will be 1GB bigger. Here's my final partition table:

When we resize /system, we're not quite giving it the whole space...I recommend running "resize2fs /dev/block/mmcblk0p25 2048M" and seeing the error...it's easier to adjust the actual filesystem size than the partition size, so we fudge it a bit here so long as it's safe. If this test is unsuccessful, it will tell you that you're allocating more blocks than you have. If it's successful, it'll tell you to run e2fsck...this is normal, and running the resize2fs command with the -f flag overrides that warning...but it'll also allow you to allocate too many blocks, hence why you run a test first as a sanity check. For this exact procedure, 2000M is the exact maximum size.
All in all, this technique can likely be adapted to other android phones. The key is making sure you resize system by the amount you take from data, and making sure you offset all partitions in between linearly by the correct amount. I'm not sure how updates will work...anything that basically lays down a partition is gonna cause issues since it'll try to resize to the default partition size. Anything just laying down new files should be fine.
Happy hacking!

I was looking for such an option as I wanted to install a bigger gapps package then just pico. But shrinking my userdata partition is not was i had in mind. I also really do not want to loose all my data, as i am leazy
so i was thinking about just resizing /cache to a bare minimum of lets say 128mb or even less. Because as i understand /cache is just used for OTA updates - if i am mistaken here, feel free to update my knowledge.
Has anybody done this? On the Galaxy Nexus this is the way to go afaik and one would not loose things in /data.

It worked, Thank you!
What i essentially did was make a nandroid backup followed by "adb pull /sdcard/" on the computer.
Followed your instructions (just before the flashing section), pushed the sdcard data back and restored the backup.
chowned and chmodded the /sdcard directory:
Code:
chown media_rw:media_rw /sdcard
chmod 755 /sdcard
Resized the /system bit, rebooted and hoped it wouldn't 'bootloop'.
The process was nerve wracking, but now the handset is ready for a future stable ROM (I'm still on stock).

So, we need to do
Code:
resize2fs -f /dev/block/mmcblk0p25 2000M
every time we flash a new ROM?

Depends on the ROM you're installing.​

Everyone must pay attention that this guide is for 32gb model........for 16gb commands are different.......pay attention else u brick seriously you phone.....

Yes, this...my numbers show the methodology, but for the 16GB nexus 5 (or any other phone) you need to start by looking at the starting state of the partition table, then do the math from start to finish. I hope I've provided enough methodology and warnings that someone will either abort or do it right.

In general I would say that's a very bad idea...however, if you're very careful and are willing to incur some risk, it could possibly work...on the N5, since the cache partition sits between system and userdata (and more importantly doesn't touch recovery) you could theoretically try it, and if it doesn't work, undo it, all while leaving your userdata partition untouched. If preserving your data is your goal...it's probably a bad idea, but that doesn't mean it isn't possible.

How about taking space from cache to userdata? 1-1,5GB'll be unused anyway and on 16gb variant it'll be nice to have some more memory to have

Aim
To convert my Nexus 5 16GB into a Pixel using CM14.1 and Stock Open Gapps (I didn't want to keep flashing random pixel-experience.zip files)
Issue (strikethrough issues are with Stock Gapps)
When using Aroma Gapps:
1. Launcher3 crashes everytime the G search bar is clicked on
2. Google Now is not on the left pane despite my chosen packages
1. I couldn't Sign into my WiFi because no soft keyboard would appear (workaround: I created a password-less Hotspot on another phone)
2. I wasn't able to get past through the Google setup process; Google Play Services would crash every time I attempted to skip Tap & Go taking me back to a SIM card missing screen. On skipping this, I get taken to Tap & Go... and repeat
I've wiped all the caches (of course). If anyone has any ideas, it would be great.
Question to @surfrock66
You have a parted command that says:
Code:
~ # ./parted /dev/block/mmcblk0 mkpart primary 3056MB 30.8GB
Should this not be:
Code:
~ # ./parted /dev/block/mmcblk0 mkpart primary 3056MB 31.3GB
I may not have understood this fully
Thanks surfrock66 for the original method; my method varies slightly and is as follows:

No, this is not necessarily true. You will need to use Parted to analyse the partitions and then make the relevant modifications. Again, do not try this unless you are willing to potentially brick your device.

In TWRP, you have to choose to mount your system as read/write, for me with TWRP 3.x it's an option right when TWRP starts. If you don't do that, you can't write to / and thus can't copy the file over.

I don't have that device, but the original post here should have everything you need to re-create the process for another device. You'll have to re-calculate the offsets based on what you find when you run the original partition query.

CM14.1 fits on the Nexus 5 /system partition WITHOUT repartitioning.
I wanted to try this because I want to flash Stock Gapps (as opposed to Nano), hoping to get a Pixel-like experience as described in my previous post (http://forum.xda-developers.com/showpost.php?p=70145560&postcount=10). However, I had lots of crashes with Stock Gapps.
Instead, I now use CM14.1 with Nano Gapps.
If you want a more Pixel-like experience, that side-loading doesn't provide (no Google Now on the left side of the Homescreen, no Pixel-like animations on clicking the G Search Bar), I have resorted to installing the Pixel Launcher and Wallpaper APKs into /system.
Instructions found: http://android.stackexchange.com/questions/76976/how-to-install-app-as-system-app
Re-flashing a ROM will require you to re-do these steps.

Successfully moved data partition /data to microSD card /dev/block/mmcblk1p2 by editing /vendor/etc/fstab.qcom

I have unlocked my redmi 7A using unlock tool provided by Xiomi.
I can boot TWRP by:
adb reboot-bootloader
fastboot flash recovery 'TWRP-3.3.1-1003-REDMI7A-CN-wzsx150.img'
fastboot reboot
and holding volume key. ( up or down I don't remember)
I also flashed vbmeta to Disable VerifiedBoot:
fastboot flash --disable-verification vbmeta vbmeta.img
because I was modifying /vendor
Now redmi 7A was running twrp and was connected to my ubuntu PC using USB cable.
On PC I typed:
adb shell
now I got root shell. I created a directory in /mnt to mount /vendor partition.
# mkdir /mnt/dirName
# mount /dev/block/mmcblk0p58 /mnt/dirName
How did I know that /dev/block/mmcblk0p58 was /vendor? Previously I had copied all of phone's emmc flash disk to PC by:
** On PC **
adb pull /dev/block/mmcblk0
I mounted mmcblk0 image file using:
[email protected]:/home/username# losetup --show --nooverlap --partscan --find '/path/to/mmcblk0'
** output **
/dev/loop20
got partition table information using:
** On PC **
[email protected]:/home/username# gdisk /dev/loop20
Partition table scan:
MBR: protective
BSD: not present
APM: not present

you may observe that size of userdata is 64MB that is because I resized the image to reduce it's size.
from above we can see that /vendor is partition 58 that is /dev/block/mmcblk0p58
after mounting I edited /vendor/etc/fstab.qcom using nano
** On redmi 7A:
# nano /mnt/dirName/etc/fstab.qcom
I changed
/dev/block/bootdevice/by-name/userdata /data ext4 noatime,nosuid,nodev,barrier=1,noauto_da_alloc wait,fileencryption=ice,quota,reservedsize=128M
to
# /dev/block/bootdevice/by-name/userdata /data ext4 noatime,nosuid,nodev,barrier=1,noauto_da_alloc wait,fileencryption=ice,quota,reservedsize=128M
/dev/block/mmcblk1p2 /data ext4 noatime,nosuid,nodev,barrier=1,noauto_da_alloc wait,quota,reservedsize=128M
notice that I have also removed fileencryption=ice mount option to disable encryption.
I also changed
/devices/platform/soc/7864900.sdhci/mmc_host* /storage/sdcard1 vfat nosuid,nodev wait,voldmanaged=sdcard1:auto,noemulatedsd,encryptable=footer
/devices/soc/7864900.sdhci/mmc_host* /storage/sdcard1 vfat nosuid,nodev wait,voldmanaged=sdcard1:auto,noemulatedsd,encryptable=footer
to
# /devices/platform/soc/7864900.sdhci/mmc_host* /storage/sdcard1 vfat nosuid,nodev wait,voldmanaged=sdcard1:auto,noemulatedsd,encryptable=footer

to disable mountng of fat32 partition on sdcard as external sdcard
I inserted 128gb microSD card ( class 10 ) into USB card reader and connected the card reader to Ubuntu PC. created GPT patition table on microSD. left 16 GB space at begining of microSD empty so that ext4 fs is aligned with flash storage blocks. created 1 fat32 partition and 1 ext4 partition on sdcard.
after editing fstab I unmounted /vendor and turned off the phone using:
# poweroff
Inserted microSD into phone and turned on. It took few minutes on first boot.
On setup screen do not enter lockscreen password or pattern. because Phone shows incorrect password even if password is correct. I was locked out of my phone because of password error. I had to delete some file/ files ( I don't remember filename ) from /data by connecting microSDcard to pc to remove screen lock.
Microsd card is slightly slower that emmc nand. I have noticed that the phone took slightly longer to start a game after moving /data to microSD. I am on stock rom and haven't updated after fstab modification. Sometimes there is "Updater has stopped" error 1 or 2 minutes after boot.
Pros:
prevents damage to EMMC NAND caused by writes as most reads/writes are from microSD.
easly increase storage by using larger sdcard.
Cons:
cannot use screen lock. phone will be unlocked always.
Phone may have issues after OS update. Or can't update at all. (I have not updated so cann't say)
