Hi!
I have a huge problem related to most likely /persist folder.
Restoring TWRP backup (which included /persist folder) broke down entire /persist folder so I cannot turn on WiFi. Of course I am stupid, and my backup file has dissapeared after full (with internal storage) wipe...
Can someone help me? Will backup from another phone help? Or maybe flashing stock ROM?
My device is XT1032.
EDIT: I managed to do it myself.

Hi, was wondering, if I was to make a full nandroid backup online, would I be able to recover my device even if its in a bootloop state? Not that my device is in a bootloop state I was just wondering.
Thanks, Mohan.
Yes, you can use a nandroid backup to recover from a bootloop, as going into recovery bypasses the normal boot sequence. It is always recommended to have a nandroid backup of your last good configuration in case you are modifying anything that might cause your phone to become unstable.

Ohh right thanks, another question, im backing the data on my device right now, however its skipped /boot and /recovery and is only backing up /system and /data, are the first 2 needed or will i still be able to recover my rom and data without them?
All your user data is stored within the /data folder, with the /system folder containing all of your ROM files. You will not /boot or /recovery for recovering your data.

Ok, thanks for clearing that up for me.
My Mum's managed to mess up her tablet (seems to have reset it but not factory reset, as it's still encrypted, password protected, etc, just all her apps and even Apex Launcher have vanished) and the only recent backup I can find is a TWRP backup made with Online Nandroid Backup.
TWRP doesn't seem to recognise the files however, as it doesn't list any backups. I looked at the log and see that when pointed to the internal storage (which it can't mount as it's encrypted), it looks in /data/media/TWRP/ and I've recreated that structure on the microSD (where the backups are), giving me /data/media/TWRP/BACKUPS/0000000000000000/2015-04-05--07-14-50/
In that folder I have:
boot.emmc.win
cache.ext4.win
data.ext4.win
recovery.emmc.win
system.ext4.win
and .md5 files for each of those.
The .win files I can open with 7-zip, to show the files without that extension (e.g. data.ext4).
If anyone could help me restore this backup I (and more importantly my Mum) would be very grateful!
I tried installing Nandroid Manager and ES File Explorer and both failed, so something's clearly messed up. SU 2.46 is installed and I checked root with Root Checker and updated Busybox.
OK, I found a good tip to make a new backup (I just ticked boot to make it quick) and check where TWRP puts it. It turned out to be /micro_sd/TWRP/BACKUPS/Lenovo_A5500-HV/
So I moved my existing backup folder there, formatted /data to remove the encryption and then I was able to restore the backup. Now the tablet's stuck in a boot loop though and I can't even boot into recovery, so I'll have to start from scratch and then try and restore just /system and /data.
Hi , as the title says, I want to go back from NexusOS 9.0 to the Nougat Stock ROM on my SM-G920F.
Fortunately, I made a /system + /data backup with TWRP before flashing NexusOS.
I was thinking of (correct me if i'm wrong) :
wiping system, data and cache
Restore backup from within TWRP
Will this procedure allow me to get my stock ROM back with all my apps, sms, contacts,calls, etc... ?
Wait for anyone who has done the exact change, but I'll add:
/data/media/ (.../sdcard, internal storage) might not be backed up and could be lost once the /data is formatted.
Any loss of cellular is probably related to /data/data/..., and the firmware in use, backup the EFS anyway but don't wipe the EFS or restore the EFS (unless 100% sure)
Thanks for your answer !
Internal storage isn't wiped when wiping data (I kept all my files when installing NexusOS) and I didn't experience any problems related to cellular, so I guess EFS hasn't been modified/wiped.
But you're right, I'll wait a bit too have more advices
Nobody ever did this procedure ?
I lost the funcionality Phone in my N8000. I think i lost the imei e someone more else. How can i restore my efs? I have a backup of my efs in format zip and format tar made 5 years ago ( i dont remember what application i used) , but i can not install via Odin or via Twrp, said Invalid Zip format on checking Digest File. I think the problem is checking the md5 generation that is not compatible with Odin and Twrp.
Someone can help me to restore the /efs partition with old backup. Thanks
see your identical post .
I resolved this situation, using Solid Explorer and Qute Terminal with root.

Thanks
It is not solved, when reboot the system, the imei of phone, N8000 is another, is from another file from i used to recover.
Manually from my backup what files and permissions i have to copy to the /efs in root of my N8000? First i copy nv_data.bin, nv_data.bin.md5 and the folder /imei and works. I do not known the original permissions of the files, perhaps now the problem is this.
Someone can help me?
Thanks
With this guide "[GUIDE] Recover your IMEI in 9 steps. " https://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021 , i resolved my problem with imei, no problems with reboot, but now i did not have access to Wifi, i can not connect to my Wifi Network.
Someone can help me, how can activate wifi? What files i need to copy from my backup? Before clean the /efs i made a backup the old efs.
Thanks
Flash stock rom .
I flash the stock rom and now i did not have any problems
Hello
I wanted to install Syberia A12 from stock A11 and I got stuck somewhere in the process.
So I'm stuck with the internal storage on the phone (not backed up) that is inaccessible since it's encrypted and the rest of the partitions backed up on the pc using adb backup (a single .ab file).
In theory I should restore the partitions to the phone and I should be able to access everything and boot as it was before, right? However now I have the syberia ROM installed and I'm not rooted anymore (and won't boot).
Can I restore /system like this?
What I care about is access the internal storage, what can I do?
I tried restoring the entire .ab file, however it gets stuck at "restoring efs2" and I should only try to restore /data and /system but I can't select specific partitions being a adb backup with twrp.
All tools I tried to extract the content fails.
