Default [Q] TWRP Backup Failing

Hi all,

I have a Droid MAXX with 4.22 (jellybean) installed, unlocked bootloader, rooted, with TWRP 2.6.3.1 installed.

I use Android File Verifier to verify backup and keep getting Java read errors on the backups. If I open the backups in Titanium Backup, several files are missing, so the backup if definitely bad. I've made several backups, all with the same error. I backed everything up on my Internal SD and used TWRP to wipe the internal SD, thinking the partition was corrupt. No difference.

I installed TWRP 2.7 thinking that might help. The files seem to verify through a little further but then fail with the same message. I've attached a screen shot of the error message.

Any thoughts? I'm freaking out not having a good backup and I'm scared that maybe the internal SD in bad? I hope not, I like my unlocked MAXX! Is there a way to format or sector check the internal SD? I don't think the wipe in TWRP actually does a format, just an erase.

Anyone else having similar problems? Things to check?

Thanks!

Mike

Have a look at and/or post your log from twrp. You can find this under advanced options then copy log or use the command adb pull /tmp/recovery.log.

Also, I know in the past titanium backup hasn't been great at extracting nandroids. Try https://play.google.com/store/apps/d...3t1c.bkrestore and see if it makes a difference.

Have you actually tried using the backup to restore? You sure the app you are using to check isn't the issue?
Please note, I do not do ROM support via PM. If you have a question, ask in the device thread. Thanks.

Switch to Philz it will handle twrp bu's too. You can watch the md5 check going on before you command the restore to take place. At least on 624.

Android File Transfer SUCKS! Is there a no root solution for Osx? I am resorting to Parallels DeskTop-W7.

Thanks for the help and suggestions. Here's what I found:

Tried TWRP 2.6.3.1, 2.6.3.0 and 2.7, all with the same result. Corrupt files. I verified this using Android File Verifier (great utility, used for years). When running Calc MD5 checksums on the individual backup files, some would verify and others would not.

Running multiple backups with each version resulted in failed backups. On a weird note, I could not remove the TWRP directory using either Root Explorer or ES file explorer. Both would cause the phone to reboot. The only way I could remove the directory was using file manager in TWRP.

Switched to Philz recovery and ALL backups verified just fine! Although it doesn't have the fancy interface or some of the features of TWRP, it gets the job done!

My conclusion is that there's some sort of issue with TWRP writing to the internal SD as proven with the incomplete backups and the directory problem it caused on the SD. I would recommend others use the Android File Verifier to make sure they are getting complete backups!
