Uninstall MCR without loosing data?

[Guest enemywithin]

I'm trying to go from MoDaCo Custom Rom 3.1 to stock ROM while keeping all my apps and settings. Have tried both flashing the stock ROM (boot.img + system.img) and using the official RUU and then restoring data.img via Nandroid. Either way, I end up in a boot loop.

How can I do this?

(Is there a log file containing the reason for the boot loop...?)

Connect to USB, run "adb logcat" and you'll see what's causing the loop, or just post the screen/text on some forum :D

Think maybe some settings wont work on stock ROM since they come from a rooted ROM.

I tried to restore some settings on to 2.1, and even sense just FC'd.

And btw, nandroid backups your whole system, not just settings, so when doing a nandroid restore you wont have the stock ROM anymore... You'll just restore back to the 3.1 ROM.

Try using a backup app (not Titanium, since it's just for root).

If you want to keep settings while going to an RUU ROM, then you're out of luck unless you back them up, flash the ROM and then manually copy things back via the adb shell in the recovery menu.

Also, it's "losing".

Care to evolve? What exactly (files and such) is one supposed to pull from the phone for a later restoration?

EDIT: Except for the apk-files that is. Data- and settings files?

the contents of /data/data should do it.

the contents of /data/data should do it.

OK, which files does the app Titanium Backup backup then? I'm guessing the apk, a file containing user settings and the Market link one? And also, are all of these files located in /data/data?

The need arose and I gave it another try.

Didn't know the debugger was enabled during boot. Way cool. Not sure what to conclude from it though...

Not if you remove everything but data.img and edit nandroid.md5...
