Hello,
the last days I faced an issue that a restore with TWRP did not work again anymore completely.
Restore of data partition failed with createTarFork() process ended with ERROR = 255.
This I did before:
- rebootet to TWRP recovery
- did a factory reset, and also wiped system, data, cache
- started restore
Checking recovery.log, it was said that file external_sd.f2fs.win was not found.
That is correct, as in my backup there is the file external_sd.ext4.win, and not external_sd.f2fs.win.
When checking my filesystems (TWRP, terminal, cat /etc/fstab), all of them (system, data, etc.) are ext4, only the external_sd was f2fs …
I guess this was the reason why TWRP restore failed.
I’m wondering now why / how my SD card was reformatted from ext4 to f2fs, without I have noticed it.
Has someone else experienced something like this?
The full ‘repair’ was a bit elaborate, it started with the question ‘How to get back Ext4 on my sd card’, so that afterwards also the TWRP restore would finish without issues.
I finally did it that way that I started from the scratch:
- full, fresh installation of the FPOS package “FP2-gms-18.04.1-manual”
- after first start of this version, the phone was encrypted, and then the SD card again was formatted as ‘internal memory’
Checking again then in TWRP the filesystems, now also my SD card again was back to Ext4. And then also my old TWRP backups could have been restored without problems.
If next time the sd card’s filessytem again is f2fs, is there an easier way to get it back to ext4? Best case without loosing the data on SD card?
