[Q] Revert Defy from Quarx CM10 to CM7.2?

[frickelbarde]

Hello,

I currently have defy with the later lens with the latest Quarx CM10 nightly installed. While CM10 is generally awesome, it turns out to be not stable enough (radio crashing, sudden restarts) and a bit too slow. Now I would like to downgrade to CM7.2.
I tried just flashing CM7.2 after a wipe which yielded a non booting device and me flashing back CM10.

Does anyone have any experience with reverting the Defy to CM7.2?

Thanks for your help!

You should change ext4 format of data to ext3 before flashing cm7.
1. Boot to recovery
2. Wipe Delvic cache, data/cache
3. Go to tools menu in recovery.
4. Convert file system from ext4 to ext3. It don't show any progress. Wait for few time. It shows done.
5. Flash cm7
IMPORTANT don't attempt another wiping of data/cache after filesystem conversion.

I want to do the same with my green lenses. I have CM10-2nd boot, should I install CM7.2 for defy+ or just regular defy?

thanks in advance.

I don't know WHY all this redundant question? Is so hard to search a little? This problem was debated by enough time.

Sorry, I did search and found just this thread...

Just tried here, and cm7.2 for Defy+ worked just fine.

Hmmmm, last time I had to do this I reflashed a stock Froyo rom and did the whole process of rooting/installing 2ndinit/installing CWM again. Installing CM7 then wiping dalvik/cache/data did not work.


If a simple flash/wipe doesn't do the job, reflash Froyo again and follow the instructions to install CM7.

I haven't got the option in Tools to format in EXT3, there's only options to share SD, drivers, systems... Why?

I'm using a Quarx CM10-20120924-NIGHTLY-mb525.

Maybe I need to upgrade to CM10.1 to have that option? Which ROM could be good?

I'm using a Defy (mb525)

Just wipe from STOCK recovery .. it will format partitions to EXT3 and CM7 should boot =)

Wipe from STOCK recovery and then go to Custom recovery and flash directly the rom?

No just install CM7, GAPPS, and reboot to Stock recovery and there do Factory reset and reboot.
Now your CM7 should boot

Similar, but a little different

My requirement is to give CM 10.x one more try, this time with a clean install.

So, what should I do?
I posted here: http://forum.xda-developers.com/showthread.php?t=2192807

Do I need to use stock recovery, format, install SBF and then install the latest nightly?
Or something else as well?

CM 10.1 to stock

I have gathered the following instructions so far:

1. Boot to recovery
2. Wipe Dalvic cache, data/cache
3. Go to tools menu in recovery.
4. Convert file system from ext4 to ext3.
5. Flash stock ROM (Where can I find this?)

Once I am with stock ROM, I would like to install CM 10.1 again, since I am not happy with the performance of the current CM 10.1 (perhaps 2 months old), so I would like to start from scratch.

Am I missing anything important?

Once you wipe data, system and cache in TWRP(of your current installation), your new installation is clean(as it would after stock rom/sbf flash)

You can cross check using the inbuilt file explorer in TWRP
