[Q] Problems installing CM9 roms with different kernal

My defy was using cm7 2.3.7. Then I flash the new ICS rom(7-12) and then (23-12), so it is a gingerbread kernal. So when I hope to flash a ICS rom with froyo kernal, do I have to wipe data or is this a must? Thank you

[Q] Defy+ doesn't boot CM7 nightly roms

Hello,
I have installed CM7 for Defy(not plus) in my cellphone perfectly.
So then, I found the CM7 Defy+ nightlys and I'm trying to install it. But when I install the ROM on it and reboot, it stays in the initial logo forever.
Could you help me?
Best regards.

please help

Try another rom, like MUIU or any other rom and see if the start loop is overcome.

Did you wipe the memory after?

If you want to instal defy+ nighties, you first have to flash the gingerbread kernel. (CM9kernel.zip)
So now flash the stock ROM and start again. You probably downgraded to instal three normal defy nightly do you have to flash a defy+ ROM with the same bl nr. After that root instal 2nt... and flash the defy+ nightly (and wipe). If you want to be able to switch, you will have to flash the downgrade sbf again and flash the CM9 kernel. Then you can switch with just flashing the kernel and ROM (sbf wipe)

Do cm7 nightly have these fixes? I'm running nightly now and camera seems ok, but I don't know yet about the battery.

[Q] back to cm7

Hi,
How I can downgrade cm7 from cm9? Normally wipe data&cache and then flash cm7? i haven't backup.
thank you

It depends on which version you're running, if you're using the gingerbread kernel with cm9 then you can't downgrade until you get the froyo kernel. anyway let's assume you have froyo running then a simple full wipe and choose the ROM you want and flash. if you have the gingerbread kernel just full wipe choose the ROM and flash it like before, but you have one more step find the zip with the froyo kernel and flash it right after the ROM.
If you can't be bothered with all the just use a full sbf and start clean from rsdlight.

[Q] Defy mb525 - Don't know my CG version / What room to flash?

I bought a used defy that had already been flashed and i don't like the rom.
The idea was to downgrade it to its original rom or change to another one directly.
But i couldn't find my CG version, how do i find it?
I have a green defy, which rom can i flash?
Can i do it directly or i have to do the downgrade?
My phone:
- android version: 2.3.7
- System version: MIUI-203160
Thx!

Since you have MIUI I think you got Gingerbread kernal

u have froyo kernel as miui is based on froyo kernel(i think)
ur boot loader cg version should be 4...

Thank you all for answering!
But, i'd like to know if i should do the downgrade or flash other rom directly?
And, what rom should i flash?

Try to flash a Froyo, maybe a deblurred one... If it works, you have a cg4 bootloader. If not, you have a newer bootloader and downgrade is more difficult.
After flashing Froyo, i advise to install CM7. Maybe you like that.

[Q] How to go back to MIUI Pickachu Edition 2.xz from CM10 nightly (18-Nov)

Hi folks!
As the title suggests, I want out from JellyBean and back to MIUI Pickachu Edition 2.xz
I think the latest 2nd boot builds have the GB kernel since I see 4 Vsel levels, so should I flash the froyo kernel?
If so, what should be the order of flashing ROM -> Kernel or other way round?
Also, I have a nandroid backup of when I had MIUI. What steps do I have to follow to restore it, i.e, do I have to flash the ROM (and/or kernel since I was on froyo kernel when the backup was taken) to restore nandroid?
I read a lot about the fuss of latest nightlies changing /system and /data to ext4, but in my case they are ext3, so I guess I should be alright?
Reason for going back is LAG! the immense amount of time to open stuff. I tried loving it, but its just too slow to the point I feel like its running Windows 8 on Intel 8086.

Please post all questions in Q&A. Thread moved there.

Hi!
My friend was in same situation and he went ahead and tried to flash MIUI Pickachu edition, but his process got stuck and now his Defy won't boot.
Hes now flashing stock Froyo sbf.
Thats the reason why I need to know instructions to get back to MIUI without going through sbf flashing.
Any help gladly appreciated!

how do I install miui and cyanogenmod both on defy MB525

any help in installing miui on defy would be much appreciated.

You need to flash a Froyo SBF. For some reasons going back to 2.3 always ends in a cache error, flashing 2.6 kernel, nandroid, fullwhipe etc. doesnt work

R U on Froyo or GB? if Froyo try to flash fixed sbf I will attached if needed.

Just flashing froyo kernel was ok for the 2nd boot builds upto 9 nov builds.
From 9th nov builds the cm10 rom formats our defy to ext4 file system, so in order to downgrade we need to flash the sbf.

My friend, thats what I have said, in my OP,
I have checked using mount command from rooted shell and I can confirm that my /data and /system are STILL in ext3 even though some say that the latest nightlies change the fs while formatting.

Try restoring your backup, you may succeed, otherwise you need to start all over again, with the sbf. I find it better to start all over anyway, no matter, what rom we are talking about. Those installed over a freshly flashed sbf proved to be snappier and absolutely bugfree - at least for me.

Simply try to restore your backup. I tried many roms so far, aslo the newest by Quarx and Epsylon and i always worked for me to install a new rom/zip/ withour anything further. Never installed a sbf.

Was quite late in posting a reply but I did end up flashing Stock Defy 2.2.2 SEA sbf.
I did flash successfully MIUI (Pikachu edition) but it was a bit off, so took a backup and flashed sbf.
Have been on stock ever since (been kinda busy).
