extractTarFork() process ended with ERROR: 255
This message appeared when I restored my backup.I have 2 backups and the message still appears.
I already unticked firmware and bootloader when recovering but still wifi,mobile data and bluetooth wont work! Im desperate and in need of help! What should I do? I heard some users flashed a firmware but still didnt work for them.

Which TWRP version? Did you use compression when you created the backups?

[Q] EFS restore error

Hello, I'm new member in here. Today I flashed UltimaROM to my SGS3. Before the flashing I installed Philz touch recovery and saved Nandroid, modem and EFS backups in my PC. After the flashing no IMEI number was shown and I got a message saying " Insert SIM card....". So i tried to restore EFS in custom restore option in philz recovery. Even though it showed restore successful , IMEI number is still unavailable and i couldn't connect to mobile network. I also tried ktools to restore efs but no result. Can someone please help me regarding this issue.
What version firmware did you have before you first flashed? If it was really old then that could be the problem.
Flash a 4.3 stock rom, factory reset them boot and see if your efs is read again.

Thanks for the reply. I had 4.1.2. If I flash 4.3 stock ROM can i retrieve my IMEI ?
If you flash a 4.3 stock it will update your efs to v2 and should enable it to be read in all newer firmwares.

Baseband: unkown and unable to retrive iMEi

I tried unlocking my bootloader unofficially and bricked it, then trying to fix it I may have accidentally wiped all my partitions.
Luckily I followed the guide and unbricked it via the 'teardown' method, flashed V7.2.3.0.LHOCNDA with MI flash and it is now up and running again.
The issue now is I cannot turn on Wi-Fi and the phone cannot detect my sim card. Baseband is unknown and i have no iemi.
I have flashed several different versions and it is still the same.
I am now rooted and have twrp recovery
Could wiping all the partitions do this, is it reversible?
BTW: it a 16gb Pro from china if that helps

[HELP] no wifi, no recognised sim following a faileed TWRP restore

[HELP] failed TWRP restore,
now no wifi, no recognised sim,
have factory reset but as no recognised sim or wifi unable to activate then starts to boot loop .
if restore old data and system and EFS. still no wifi or recognised sim
history of problem:
i was on original miui that shipped with phone. had a failed update (OTA) yesterday and lost root. was trying to get root back. but was getting lots of errors so restored system then first restore failed.
not sure if it has deleted the modem partition which needs to be restored but not sure what that partiition is called in miui.
any ideas?
I think there was a problem restoring the 'firmware' partition that caused the problem.
Just flash firmware file and then restore... (Never restore firmware)
I would flash a MIUi ROM via fastboot to make sure that you have a "clean" installation.
Restoring wouldn't work.
Eventually downloaded a new ROM (globe ROM) and installed it
