[Q] problems after omnirom install and fallback

Hi,
I've got a xoom eu, the tablet was flashed for long time with different rom (CM, EOS9), I was using TWRP.
Some days ago I've installed TWRP bigpart and latest Omnirom, everything was working fine.
Before the procedure I've made a nandroid backup of the CM 11 and TWRP that was running before the new installation.
After some days of playing I've decided that I prefer the old CM, after taking a second nandroid backup, containing Omnirom, I've tryed to restore the first backup....
A this point everything is screwed up, no recovery, no boot.
I've restored with RSD the original stock HC rom, this works well, after I reinstalled TWRP bigpart but if I try to restore one of the 2 nandroid backup the process failed.
It seems something got messed up in the partitioning scheme.
So what I can do to restore "original" partitioning scheme? At this point I can continue to use the partitioning modified by the bigpart procedure.
Thanks for the help.

[Q] Flashing a new Rom help

If i clean flash a new Rom but restore the data part from a backup i did earlier from another rom from recovery will it work? Im using TWRP recovery.

ive always had mixed results on this. if youre going from a TW ROM to an AOSP or AOKP rom, likely not. If you use TiB and backup your apps and their respective data, and restore them via the same method, that 99.9999% of the time works

[Q] Nandroid backup and restore not working

Hi guys,
after many atempts to find solutions and several hours without success I hope someone here can help me.
My configuration:
Phone: Nexus 4 16GB
ROM: Resurrection Remix LP v5.3.9
Kernel: 3.4.106-unleashed-101u+
Recovery: CWM 6.0.4.7 touch
This combination really works well. But when I boot into recovery, making a nandroid backup and afterwards restore it, I get a bootloop with the boot animation from the rom. The backup itself has around 2GB. Both, backup and restore processes are confirmed by cwm without errors.
I already tried to clean cache and dalvik cache before I made the backup, but restoring also doesn't work. A dirty flash of the ROM after cwm restoring (as a read in another thread) didn't work.
Is it possible that my cwm doesn't backup the preload partition (mentioned here)? Can the kernel or the ROM be the reason? Any other hints or a guesses?

You can update your CWM recovery or try other, like TWRP.
With TWRP you can change what partitions you want to backup
Sorry bad english

Upgrade of CWM is not possible, as 6.0.4.7 is already the latest version.
In the meanwhile I did some further tests: CWM 6.0.4.7 without touch is not working, too: The N4 gets stuck to the rom boot animation.
TWRP backs the same partitions up as CWM does, but works! I'm happy to be able to make and restore nandroid backups.
Still I'm wondering why nandroid backups using my former favorite recovery CWM don't work

stock recovery+Titanium Backup or custom recovery

Is there a necessity to install a custom recovery when I'm running on stock rom? (never changing to custom)
If I factory reset my phone and try to restore everything, only titanium backup is needed right? the system apps are the same so titanium backup would restore them. In this case is a custom recovery necessary?
I'm on android 4.4 and rooted but bootloader is locked. I understand the differences of titanium backup and custom recovery but I wanna know if custom recovery is needed on devices with stock rom+titanium backup

If you are rooted then yes its always a good idea to have custom recovery so you can make a nandroid backup of your stock setup, then if later you have issues that you can't get straight you can restore the nandroid and be back to normal, nandroid backups are backups of your entire device, titanium backup only backs up user data(apps you've installed, app data, contacts, pics, videos, music and things like that).
Titanium backup does not back up your boot, modem, system or recovery partitions and those are the important parts, the stuff titanium backup only saves non essential stuff.
If you don't install custom recovery and you have issues then your only option would be factory reset or reflashing stock firmware, these would wipe any data that you want to keep.

TWRP Restore Selection

Hi Everyone,
I'm looking to restore an old backup from TWPR. Both current and the backup are OOS11. I'm going to be looking into upgrading to 13 (I didn't like 12 when i tried it almost a year ago).
Reason for me to restore this backup isn't for upgrading, its that there is some contact information that didn't get synced properly and then titanium backup doesn't have anything (I have restored al the apps to a different phone i had and it didn't restore any of the ones in needed) and want to see if i restore this backup if they will be there, then I'll probably do a MSM restore, and then update all the way to 13 since there is no 13 firmware for MSM.
When I do backups, I backup everything in TWRP, but I haven't done a restore with TWRP on this phone and I know some phones there are some things you just don't restore and want to know what those are.
Thanks

Since you're on OOS 11, use the restore procedures listed in https://forum.xda-developers.com/t/...ect-8t-kebab-2022-03-09.4302449/post-85292199
I strongly suggest you ONLY restore the Data backup, not any other partition.
