Hi guys have weird problem with my phone. Sometimes when I want to make nandroid I can see error 255 always on system partition . When I restore system partition I can do nandroid.
Next thing, when I want to delete any system app using titanium backup, after restart app is back again and im not getting free spacer in system partition. Also very often when I restore nandroid system doesn't want to boot, it just stuck on boot logo.
It is happening since last few weeks. What should I do to fix it?
Format all partitions then clean flash of rom?

That would work if you arent rooted with otg ...the you could image the system and fix it on a Linux box with fsck

The method you mentioned will work. Format everything and reload. I wish that recovery systems for Android supported fsck. Actually, if you have busybox installed, even under tmpfs, you might be able to get to a shell to run fsck. I can't try it now, but it worth a shot.

No Way to run fsck. I will try to format everything later then send files from PC and install fresh system on the phone.

for future reference, there is a "Repair filesystem" option in twrp. It says it runs e2fsck, which works for ext4. It won't hurt an f2fs filesystem, but I don't think it will repair it either. I'm seriously considering switching my /data to ext4 just so I have proper recovery tools.
My OP3T does have fsck.f2fs on the system, which means you can fix your data by opening a Terminal session from TWRP and then running :
Code:
fsck.f2fs /dev/block/dm-0
should fix your data corruption should you see this error again. For ext4, you use e2fsck rather than fsck.f2fs. This is also what you would use on /system (which is /dev/block/sde20 on my phone) should that ever be mounted read/write and get corrupted (pretty low chance even if you do mount it read/write as writes are low frequency and ext4 has a rock solid journal).
WARNING: Device numbers are for my OP3T and may be different on other devices or even on non-US devices.
Hello all-
In the process of trying to upgrade to OOS 5. I made sure to make a backup of the entire system (system image) in TWRP before proceeding. I also backed up the Boot image and Modems. I had the entire OOS 5 rom ready to flash but before doing so I elected t wipe Dalvik/Cache, Cache, Data & System as I always thought you have to do a fresh clean install when changing versions (7.1.1 to 8.0). The first error I encountered was that it couldn't flash the file. Then when I tried to restore my backup...it does the process with no errors yet when I try to reboot I am told no OS installed. What has happened and what can I do since I always make these backups to be safe?
Thanks all!
Plug your phone on a PC (with the phone in recovery mode), move your backup (sdcard/TWRP/backup) on your PC to keep it safe. Next follow the mega unbrick method 2 (just Google it) on OnePlus forum, update your phone to the version that you were and reflash TWRP and copy your backup from your PC to your phone (in the same location than before) and try to restore your backup.
Error installing OOS 5
Thanks all! I thought a System Image backup was all I needed and had no idea I also had to restore my Boot Image backup. Once I restored that backup I was good to go. Oddly though I didn't have all my apps and data on the phone like I thought the system image backup would have. Honestly I don't care as long as I have a phone again.
On a side note, I have the full OOS 5 ROM on my phone and when I try to flash it I receive an error. The error message states as if the file os for a One Plus 3 and that it cant confirm what my device is? I have always downloaded the full ROMS from OP site and nver had issues upgrading in the past. Any ideas? Does the version of my TWRP matter? Please advise.

System image is rarely useful, it's a full Byte by Byte backup of the system partition ( meaning even the empty Bytes are saved). System partition means that boot one isn't concerned. And system partition means that data partition isn't concerned either, so no user apps or data.
Better to stick to /boot /system and /data backup.
You must have latest official TWRP 3.2 for Oreo ROMs. Or blue_spark latest (8.61 version see blue_spark kernel thread OP)

Thanks man! Good information to have moving forward. No sense in backing up partitions that are not useful and only take up space. Can I update to TWRP 3.2 right in the TWRP app or should I download image and flash within TWRP? I am currently on SU 2.82....is that compatible with Android O?

Yes update from within TWRP. I think superSu 2.85 should be good or Magisk 14.0
I dont know what I did but I know it was my fault.
Whenever I try to create a full backup of all partitions I get "createTarFork() process ended with ERROR=255"
But when I exclude the System partition it works fine.
So if I restore everything else later on will everything work fine? I'm not exactly sure whats getting left out in the partition.
Btw, my bootloader is unlocked, I'm currently on FreedomOS 2.1, I have Magisk, Xposed, all the good stuff...
ALSO! I did an ADB backup on my computer with "adb backup -apk -shared -all -system -f"
I'd be fine with the ADB backup but "backup.ab is only 1.5 GB and my nandroid backups are usually around 11GB...

Team Win recommends using the system image backup instead of just system for dm-verity devices, but I still get the same problem as you when trying to perform a backup. What you could try is clean flashing the ROM and then just restore data from ur backup. That should work.

Yeah I read in other places a fresh flash would work but I wanted to weight my options.
How does one go about doing the image backup? That sounds a lot better.

When you select backup in TWRP, it's one of the available boxes to check. Uncheck system, check system image. This hasn't solved my problem of backups not completing though. I always remove my fingerprints and pin before a backup, and I've been able to complete backups before, but usually the problem lies in encrypting the backup itself. However, I've still had backups hang at 95% even without encryption. Maybe someone else can shed some light on to why this is happening.
the createTarFork() process ended with ERROR=255 is not from system its from data and issues with parallel apps on ur OP5T
download Android Terminal and type
Code:
su
pm remove-user 999
then u can backup with twrp, never tried to do a restore yet though
Hello
This is a TWRP recovery for Motorola Moto G5 Cedric for arm64 ROMS, with encryption support, backup support for persist and efs partitions and possibility to flash/backup logo boot image.
I need review and test, especially for the storage decryption and/with LineageOS fingers-crossed. I was able to test it on my device (XT1676 3Go).
It is my first ROM so it is possible that there are bugs.
- Be carefull, there are problems with the backup system :
Just wish to come here and tell you guys to AVOID using this recovery, it seems to have a serious bug.
I just backed up my entire data partition (and enable digest verification) and restored the partition afterwards and the phone didn't boot.
Then I tried restoring it with verification enabled and the hashes didn't match.
In other words, for some reason, the generated backup was corrupt.

I just tested it and it decrypts my internal storage normally.
Just wish to come here and tell you guys to AVOID using this recovery, it seems to have a serious bug.
I just backed up my entire data partition (and enable digest verification) and restored the partition afterwards and the phone didn't boot.
Then I tried restoring it with verification enabled and the hashes didn't match.
In other words, for some reason, the generated backup was corrupt.
Of course I could make another test but it'll take just a long time to backup everything again, so if anyone wants to test it, feel free, but beware, you could have a hell of a headache finding out the backups you made were useless.

I have backup up data partition from my TWRP, reboot one time to recovery, restore the data backup with digest verification, and reboot to LineageOS, with no problem (my rom is LineageOS 16.0 without encryption.)
I think there may be 2 errors (maybe more) :
1) There is a problem with data restore when encryption is enable. I can not test this scenario for now, but i will do it as soon as i can
2) Was your backup stored on your SD card? if so, it is possible that the sd card may be damaged, because it is too old or of poor quality (more info here : https://photo.stackexchange.com/questions/40489/what-causes-an-sd-card-to-go-corrupt )
if you have other information or other ideas, do not hesitate to share it!
if people want to participate, try to save the data partition and restore it, especially with the encrypted partition :good::good:
be careful, make a backup of your data before test

I agree it may be any of the 2 problems.
My data partition was indeed encrypted, and yes, my SD card is not what I would call genuine, though I think that's not the case since the card is relatively new and I never had any problem related to data corruption.
Anyways, thanks for your effort.

Oh ok, there are chances that's why the backup did not work .
This recovery is mainly intended for arm64 rom !
Just wanted to say that everything worked well for me in backing up and restoring the OmniROM, on both decrypted and encrypted phone.
Thanks @Akipe for the great job

forgot password to decrypt??
hi,
first, sorry if this is the wrong place to post this. right now, when i install the 64 bit twrp i am asked for a password to decrypt my data. i have tried some passwords i think i would have used, but those don't work and i get a message also saying that the default password didn't work - i haven't typed a default password, though, so i assume there is a default one that twrp tries automatically. in the past, i did try a rom requiring 64 bit twrp and i am guessing i set a password other then the default to encrypt/decrypt, but i went back to stock without issues so have not thought about the password and cannot remember what i would have used. i wanted to try dotos on my phone, which i assume requires 64 twrp because i got error 255 when i tried to flash without twrp64. so i installed twrp64 but cannot get any further. so here are my questions:
is there any way to decrypt the data if i forgot my password?
if not, can i format the data while encrypted to install the new rom? if i can do that, what should i back up? i have pictures and other necessary files backed up, so i am not worried about completely wiping the phone to start over. however, should i back anything else up before formatting? do i need to worry about losing imei or losing any partitions that would make phone inoperable or not have any signal? should i back up with twrp64 or the non-64 bit twrp currently installed? any help or point in the right direction is greatly appreciated.

You need to format data
Push back button when it asks for decrypt
Goto wipe and select the option on the right to format data
This will erase everything on internal storage so copy any files you want to keep to pc first (pictures music etc)
Once formatted data restart back to recovery to check encryption has been removed and data partition is mountable
TWRP backups do not save personal files (pictures music etc) They only backup data and system files (and other named partitions)
Once you have flashed a new rom you can encrypt again if you want to via the security settings menu in phone settings

thanks for the quick response! and just for clarification and for me to be sure, should i back up any partitions before formatting? right now i have 32 (or non64 i guess) bit twrp installed, stock rom and bootloader unlocked. do i need to take any precautions with data/imei/signal before reinstalling twrp64, formatting data, and installing a new rom? if it matters any i have the international version of the moto g5. thanks again!!

Backup efs if you want to preserve your current emei state or need to restore it in future
Hello,
this is somewhat similar to this thread, but there are no answers and I have a bit of a different problem at the moment.
I've been using official LOS 17.1 for some time on my Note 8T, but it started to get slow, so I decided to upgrade my android version and test the latest features. I downloaded xiaomi firmware and A13 ROM, flashed them, made a full wipe and... here is where my problems started. Please don't school me here - I'm pretty sure that I messed up, I'm just looking for possible solutions.
What happened?
My phone had an encrypted data partition and as I read later, it was pretty normal that A12 installation messed it. The recovery (regardless of the version) has stopped prompting me to give the encryption password, instead it was mounting the internal drive encrypted. I tried to downgrade android version to 10 (both LOS and MIUI), but I had bootloop bringing me back to recovery. I tried decrypting it via ADB, but it didn't work. Since I need my phone, I made a backup of the whole internal storage with ADB and I have it in .img form on my hard drive. Since I've never encountered any problems like this, I wasn't prepared for losing all of my data, especially pictures and Signal archive, so I'm wondering - what can I do to try to get my data back, giving I have the full memory dump and I know the password used for en/decrypting it?
Thanks in advance, I spent hours looking for an answer, but I don't feel like getting close to the solution.

Encryption is effective if you protect your phone with a password or schema etc on the lock screen.
You cannot restore data from an AOSP rom to a MIUI rom and vice versa.
The backup will only work with the same rom as the backup.
So if i have a filesystem that was encrypted on lineage os 17.1, i should make a clean install of it and then try to push the whole .img backup through adb?

the problem is i pulled the whole mmcblk0 dump with adb, which gives me more than twenty partitions in the .img file (I can easily say which one is the /sdcard one because of the size) and I am not sure if pushing the whole image with incorrect rom won't bring me to the exact state i was in before. Is there a way to push a particular partition from a .img file or should i try to push everything and flash dfe, as you're saying?

if the partitions inside are .IMG file you can restore with orangefox
pick the img and set the target to restore
restore just data 1st then DFE then wipe cache+dalvik then reboot and pray

This sounds like a plan, but to which partition should I flash it? I don't see 'data' option there.
+ just to make sure, do I have to reflash and set up the exact rom and password I was on when I had the encryption working before I start the operation you're suggesting?

aah, i forgot it don't have data as target
but there must be a way using ADB
-if you are going to restore the whole backup = no need to recreate the same conditions you did before
-if you are going to restore just the userdata backup = recreate the same conditions
in both cases format DATA is important (format nt wipe then reboot to recovery)
