[Q] Restoring apps/data from backup when going from stock to CM7 or IG? - myTouch 4G Q&A, Help & Troubleshooting

So if I have a full TitaniumBackup of my phone, and I flash from stock to CM7 or Iced Glacier, can I restore any of my backup without causing problems? Or am I stuck rebuilding all of my settings and reinstalling the apps fresh from the market?
Do I need to check the box in TB that says to try to restore to incompatible ROM versions?

IG is Froyo, so it's less complex.
You can safely restore User apps and data with TB, but be very very careful with system app data. Even the green colored items may cause trouble, as you are CHANGING the ROM environment and may misprovision something.
Nandroid backups are complete system images, useful for returning to a known state, with this caveat:

HTC Glacier running CM7 #33

I did a complete TI backup of my phone before flashing IG. I was able to successfully restore all of it after wiping the phone during the flash, without any issues.
I initially tried to flash with no wipes and had some stability/app problems. I went back, re-flashed, wiped, and just restored my TI backup with great success.

Restoring Backup

Hi, I am currently using the latest CM version, however I have decided to restore my froyo backup, is it as simple as, going on ROM manager and restoring or will i.e. the CM kernel, and other CM parts still exist when I have restored, Thanks
you need to do a full wipe/factory reset before restoring the backup and no cm "parts" will be left

ROM Backup

Hi,
Is there a way to do a complete backup of the current ROM? I know I can always reflash the stock firmware but I'd like to keep all the installed apps/customizations.
Thanks!

If you flashed CWM recovery, doing a nandroid backup (boot into recovery, backup and restore->backup) will back up your entire system, including ROM, your installed apps, accounts, settings, the whole kit and caboodle. If you're just worried about your own apps, you can use an app like Titanium Backup to back up all your apps and their data and restore them after a wipe.
Just to be clear, flashing stock ROM through odin won't actually wipe any of your apps or data, but it's usually a good idea to do so manually when changing firmware versions, as you may run into problems, usually apps force closing, if you don't.

Thanks for the info, and sorry for the late reply...
I would be interested in doing a full ROM backup. Are there any known issues in flashing CWM? so far I have only rooted the stock rom.
Thanks!

Restore fails: apps are there but no app data

I made a nandroid backup using TWRP 2.7.0.0 of a CM11 M6 install. When I try to restore it, all the apps show up but there's no data for any of them. They all act as if it's the first time I've run them. Also, all my "Accounts" have disappeared so when it first boots, I've to log into Google & Cyanogenmod again. But system settings and wifi are all there.
What I've tried:
- Tried to update to TWRP 2.7.1.0 and restore again, but no joy.
- I tried to restore the backup I made before I updated to CM11 of a CM10.2 (I think) install and that fails with no error message while restoring /data.
- Restoring app data using Titanium Backup from a nandroid backup. It crashes halfway through, though.
What I'm going to try:
- Restoring again, wiping cache/dalvik, installing same rom + gapps over the restore.
- Restoring app data from the nandroid backup using Nandroid Manager.
- Restoring apps + data from my Titanium Backup backup from about a week ago. It's not up to date so I was hoping to avoid using it.
Any other ideas? What could be causing it?
It looks like this did the trick: - Restoring again, wiping cache/dalvik, installing same rom + gapps over the restore.
I got the advice from this xda thread:
http://forum.xda-developers.com/showthread.php?t=2616143
Now I've to wait and see whether it's stable. Doing a TB backup now. I'll make an ADB one after this one, as well as another nandroid one, though I've had nothing but trouble with the last four-five nandroid backup/restores I've done.

[Q] Every App Stop Working After NANDroid

On my G900P, I made a CWM NANDroid backup of 4.4.4 stock rooted ROM. Then I did a full wipe and installed Cyanogenmod 5.0 ROM. Then to revert back I wiped everything (including dalvik cache) and tried to recover the NANDroid backup, which seems to complete without errors, but every user application will force close when launched. Also, SMS or Calls cannot connect.
So is the NANDroid backup corrupt? Did it not flash properly when I recovered it? (tried multiple times)
My suggestion would be to flash the stock rom which is the same version as your NANDroid, 4.4.4, first. Then restore your NANDroid backup.
You shouldn't have to, but it might work.
That doesn't seem to work. The apps still force close / stop working over and over. Here's a lengthy logcat. Anyone have any ideas?

[Q] Problems restoring a backup of the stock rom

I recently made a backup of my stock rom using TWRP, I then flashed cyanogenmod 12.1 and due some random reboots I wanted to restore my stock rom.. I went into TWRP, did a wipe on everything but the external sd card then restored the backup of the samsung rom boot, data, system. When it booted it said it was upgrading all the android apps then starting apps then all the apps it tried to start crashed and was left with a blank screen. Is there something you have to do, to be able to restore a stock rom after flashing cyanogen?
No, that should have worked, but I have seen that crash black screen after clearing caches in TWRP, I pulled the battery, booted again and it was fine

Wierd, yeah I tried a couple of reboots and it always crashes once it starts apps after a restore.
Try flashing a stock ROM with ODIN to get the phone back to 100% stock
Then root and flash TWRP again and see if you can restore the backup then, if not, try restoring the backup without restoring DATA which is where the apps are
If that works, you could use Titanium Backup to restore the DATA partition iirc, see if you can get around it that way
