Help Nandroid Backups (TWRP)

[Boowho]

Have done the backup.... But when trying to restore, and then boot back to system the device just "hangs"

Android 11 and TWRP for that version of Android Help???

Thanks

Try wiping cache and dalvik cache and then restore your nandroid backup.

Thanks I'll try that. BTW does a Nandroid backup include things (for example) like settings I've made to an installed app, or even things the app developer wants to hide from the user??

Yes. It's a complete backup of your phone..... settings and all.

Actually, after what looks like a completely successful restore, the device boot loops trying to reboot to SYSTEM (from TWRP)

It looks like the backup filed are something like win000, win001, etc that are actually tar files.

I'm wondering if I got into terminal mode on TWRP, could I just extract the tar files to restore the partition??

I've always used tar to b/u and restore /data/media.

FWIW, the device is a Pixel 3a running android 11 and the version 11 compatible TWRP flash file.

Help if you can...... Thanks

hmmmm in my days of rooting, i never really looked into what makes up a nandroid backup.....never went that deep.

so are you saying that after wiping cache and dalvik cache and you select the nandroid backup to restore, it just bootloops? what happened before you tried to restore a nandroid backup? was there any issues? did you try flashing a rom? do you have any other nandroid backups you can try flashing?

I've given up on TWRP..... I'm now using a Windows .bat file to backup ALL partitions on the device. It works great except throws errors on these two partitions : mmcblk0 and mmcblk0rpmb

I've read that these two partitions are not REALLY partitions at all, but are some sort of "special" files within the /dev/block directory.

The question is do I have a complete Nandroid back up without these two included?? Anyone??

Thanks
