[Q] No system apps after restoring Twrp backup of JB - Galaxy Ace II Q&A, Help & Troubleshooting

Hi
I wanted to test CM11 on my Ace2. So I backed up my stock JB 4.1.2 using TWRP backup function. After testing CM11 I've decided do revert do to JB. After restoring backup, JB booted fine but system apps stopped working. System is showing "process.gapps stopped working". Tapping dialer gives me message "app isn't installed". gmail, system settings, dialer, contacts, aren't working.
is it possible to fix this without restoring full system via Odin?

Do you formated /preload or somethink like this? In this partition, you have some apps, which stock JB needs.

[Q] Cyanogenmod Failed to restore an app :/

So i recently backed up my beautiful widgets app to titanium back up, and when cyanogenmod tries to install it / restore it, the ROM just reboots everytime. Has anyone had any problems similar to this?

Anyone having this problem?
bumppppppp

Process Media stopped working

I've flashed my phone with the latest Cyanogen mod (http://forum.xda-developers.com/showthread.php?t=957344)
I flashed the radio, then the ROM and in the end the latest Gapps... But now several things don't work. Facebook can't start and when I try to set a new ringtone, it gives me the 'process media stopped working'. Any idea how to fix this?
Ow. It also happens when I try to visit Facebook and when I try to create a ringtone via Zedge.
Nobody with tips or hints what I did wrong?
Did you wipe everything before flashing it? Data, cache, system, battery stats...
Did you restore any system data e.g. via Titanium Backup?
Have you got a nandroid backup of where you were before?
1. Yes I wiped everything.
2. I did both. First I restored with Titanium Backup. Then I tried without a restore. STill the same problem.
3. before this I used a MIUI ROM but I didn't like it.

[Q] Anyway to disable Titanium Backup in recovery?

My gf froze something in tb that she wasnt supposed to, and now whenever you slide down the lockscreen she gets a force close (process com.android.phone) so the phone is unusable. Is there anything I can do about this in recovery?
If you can get the phone to boot, you can defrost it if you can launch TB. Uninstalling Titanium Backup will not automatically defrost the app.
You can reflash the rom without wiping data (wipe cache & dalvik) to get your system apps back to normal. If you've flashed any mods or modified any system files then you'll lose those changes and you'll also need to reflash your kernel if you've flashed a different one.

Yeah I was gonna reflash the rom as a last resort. Just hoping there was some way I could undo changes tb made through recovery or something.

[Q] [ROM] wajkiui stuck in boot loop.

i ran a titanium backup on my motorola defy whilst running CM7 2.3.7.
the backup was a user apps, systems apps and user data (for those firmiliar with titanium backup)
i then booted into recovery.
> wiped data/factory reset,
> install zip file from sd card
> chose and then flashed WajkIUI 1.10.8
it then booted up and then i then put the phone back into recovery mode and then flashed the google apps 2.3.5 package and that was too successful.
i then booted the phone up and once again it booted up fine.
i then installed titanium backup from the market, then restored all that i'd backed up previously. This once again was successful. I then continued my using my phone as usual. Then i thought too reboot because i was having problems with the theme manager allowing me to change lockscreens, so i rebooted.
It then went into a continuos boot loop and it allows me to go into CWM still and the stock android recovery whilst also allowing me to go into the stock Bootloader.
but i really like the rom but this constant loop annoys me,
how can i fix this without loosing data?...
I think the problem was restoring system apps from a rom to anoter, think you'll have to install your rom again and only restore apps (not sure if restoring data would or not be a problem)
oh, so you suggest i just do a user apps+data back up instead of doing a system backup using CM7,
okay i'll try this out and get back to you thanks .

no, this stuff you mentioned is user data, that will come along on a data restore, just try to restore only apps and data, leave system apps off.
WajkIUI doesn't require gapps to be flashed from recovery, so you can skip this step next time, maybe that was the problem (i am not sure, never flashed gapps for WajkIUI)
oh, okay i'll try this method then i'll get back with the results

[Q] Regarding backups and restores. Please help!

Hello XDA, I am in need of great assistance regarding backups and restores, I am somewhat new and not very experienced with this. I'll keep this short.
Here is what I would like to do:
I have a Galaxy Nexus from the Play store and running 4.2.1 from a stock google image I flashed, I have it set up the way I want to with all my apps, etc. Turns out I don't like the performance from this version on my phone as it feels slugish so I want to either try a 4.2.1 ROM or go back to 4.1.2 but I don't want to set up everything again, both having to download the apps and setting them up the way I have them right now, same with my phone settings (brightness, keyboard settings, etc).
Can I do that and if so how? I have a pro version of Titanium Backup but having my backup restored on another rom breaks it and puts me in a boot loop upon reboot. I also tried making a nandroid backup but upon restoring it brought everything back, including the old ROM! Upon some reading I found out about the advance restore and to just restore data but that puts me back in the same boot loop on the new ROM.
Ultimately what I want to do is restore my phone and app settings in a simple way, I don't care about to manually downloading the apps but I do want to restore their settings and phone's settings in an easy way so I can safely try out new ROMs without having to set up every configuration again.
Please help me I've struggled with this for a while and it always keeps me from trying roms.
dont restore system apps/settings, that can cause you to get bootloops... you can try this if you want
- Backup your current setup either with TWRP or CWM (I prefer TWRP)
- Do a full wipe (cache/dalvik cache, system and factory reset)
- Flash the new ROM, gapps and your preferred kernel
- Restore ONLY data from the backup your made
- Reboot and enjoy

I think that's exactly what I did the last time, I created a backup in CWM, performed a full wipe, flashed the ROM, etc, booted up the phone, then went back into recovery and restored the data only from the advanced restore in CWM and that caused me to be stuck in a boot loop when I rebooted.
Could really use some help hopefully someone else can respond.

Restoring the /data partition is the problem, it contains the settings for both system and user apps. Probably some system settings are the issue.
Just use TB to restore user apps and their data and then selectively restore system data (NOT the system apps.) I usually restore only SMS/MMS, call logs, and WiFi access points.
Restore system data one or two apps at a time, rebooting after each restore. If bootloop or FC's occur then you know what not to restore next time. Just clear data for the effected app and continue.
Also, in TB the xml restore is usually a safer bet where it's available.
