Downgrade Defy+ (MB526) from CM10 Quarx last nightly to CM 7.2 stable

[euros60]

Hello,
I would know if we can downgrade the Defy+ with the last Quarx's nightly with the custom kernel to install CyanogenMod 7.2 stable and if we can take (with a data backup in recovery of course) the data from the actual version of CM10 and restore on CM 7.2 stable without problem like bootloop ?

Thank you in advance

Backup your /data/app folder

You can copy /data/app to /sdcard to save your downloaded apks.
Not sure if they are going to work.

Thank but I know already the manipulation in order to do a backup and restore.
I try to downgrade to CM7.2 stable, there is the battery problem with "?" icon, I installed the battery fix for CM7 but I re installed my backup of CM10, in fact in my precedent question I did a fault : I would to downgrade from CM10 to my rom stock's backup before the installing of CM10.

So I try also to downgrade to my stock rom's backup, same problem with unknown battery I also had the battery fix but when I try to restore my CM10's data, the stock rom's recovery doesn't see the files for restore my data, it says "no file data in this backup, no .ext3 ..."

I think the older recovery doesn't recognize the file types of CM10 recovery.


Thanks for your response !

Cannot enter recovery mode

I also want to downgrade from quarx´s CM 10 to CM7.2 or 9, but i can´t access to recovery mode. I´ve tried the button combination, and the recovery mode in android, but none works. Is there any tutorial on how return to something like stock just to star all over?

Yes you can downgrade, I did it yesterday only.

For the downgrade to CM9:
-Wipe Data /Fullwipe
-Install the Cm9 nightly you want (Step by step guide is here - http://forum.xda-developers.com/showthread.php?t=1795647)
-install Gapps
-Format Cache/Dalvik Cache
