I have the same issue, the problem not eliminated.
I wipe everything as you described, then when i restore backed up data from OTG its not restored and error
extractTarFork() process ended with ERROR: 255
My Phone is Xiaomi Mi9T.
Please help me.
That’s right. I moved this here to the Discuss category where (almost) anything goes.
If your phone was/is encrypted, before you restore the data partition make sure that the same decryption method (= the same screen lock password/ PIN/ pattern) is set up again as it was at the time you backed up the data partition.
I used this method but not worked.
I change my password to old. but twrp not restored. I get same error.
Then i delete all 999 (dual apps) in my backed up twrp images then it restored. but i lost all dual apps applications.
Is there any way to restore twrp backed up dual apps?
Dual Apps seems to be a vendor-specific feature not available in standard Android such as on Fairphones yet.
I don’t know why TWRP should care about what kind of stuff would be in a backup, apart from an available space problem while restoring perhaps, but I think probably at this point you should better ask in a Xiaomi forum.
