Can you still boot into your OS?
No, because I was on the P beta, but wiped everything including system. I tested a restore with everything else except data and it worked, just data failes, and recovery.log says "==> extracting: //data/reserve-lib/com.oneplus.soundrecorder/ (mode 40755, directory)
tar_extract_file(): failed to extract //data/reserve-lib/com.oneplus.soundrecorder/ !!!" so I'm assuming that's the issue, but I don't think there's any way to edit nandroid backup files like a filesystem, is there?

Edit: So I made the data backup into a .tar file and I can see the offending folder, but can't delete it from within WinRar, but I can make it a folder and delete it. Once I have that, how do I make it back into a .win000 file?

I think you may be able to just rename .tar to .win000, try it and see.

Yea I editited it saying I did that, but can't figure out how to make it back into .win000. I guess I will just transfer it onto the phone, backup that and then restore (as just transfering will probably mess something up)

i'm having hte same problem , i never used parallel apps and i'm getting the same error on a restore for no freaking reason!

I need to restore so badly, i can get into OS just fine now but i didn't backup my apps prior to doing the wipe after the backup.. any ideas please?

Did you get this working? I'm not very good with TWRP yet so I don't know all the lingo, but I too made a backup and receive the error 255 when trying to restore using TWRP. When I restored the backup and unchecked data like you mentioned, it finishes without error but get this error "Your device is corrupt. It can’t be trusted and may not work properly" when I try to boot it. Restoring the backup without the data box checked still doesn't restore everything obviously. I'd like to restore the data too. Did you get it all working to where you can restore all?

So I edited the backup and removed the offending files and then put the file back into the backup but that didn't work because I guess it broke the signature or something but it wouldn't restore data at all once I edited it. Idk.

I just don't bother with backups anymore, too much of a hassle haha, and it makes no sense why it fails, since I have no parallel apps or anything

Thanks very much for the response and info! No backup at all? Bummer. I've tried to backup several times using twrp and keep asking around. In the root directions it's said how to backup and restore. Surely it's been done in this os since instructions are there.

The second time I tried, I was able to backup and restore all partitions "successfully" using the newest bluespark twrp version from a couple days ago... But I get this boot issue saying the device can't be trusted and doesn't boot.
