It's the same method to install CM7.
Make sure you delete (and backup) data and cache, and then just download and flash the stable CM7 first, before the nightly builds.
The only requirement is to make sure you clear data.
Thank you so much .. and could you please tell me what kernel do I have? Newbie here

[Q]ICS ROM clarification

Hi Now am using 2.3.7 version and kernal 2.6.32.9-gb in my defy,
Am planing to install ICS 4.0.3.What kernal should download?
Becoz i already tried Mar 3 build but its stucked many times and getting restarted again so pls tel the correct methods and kernal.GApps.
Can any one help me?
If you have gingerbread kernel you need to install a Defy+ build. If you have a normal defy, I think you need to install batery fix as well. I'll try to find it. Defy+ builds work well with red lense defys, but I don't think camera works for green lense users.
Thanks...so shall I install defy + build...and kernal link available separately....what is the use of those kernal...how. and wat should be install

You already have a kernel. Or else you wouldn't be able to use the phone. You've already told me that you have a gingerbread kernel. So don't bother flashing a new one.
Gapps is on first page for main CM9 thread. Battery fix is somewhere in the thread :-/ Look around page 300

CM9 Kernel gives bootloader error. It's for froyo kernel users only (as far as i've understood)
DON'T flash it! It will soft brick your phone!

I hope all doubts over
CM9 builds,gapps & battery fix is enough to my phone to run ICS.
Have to flash above three things?
Am i right?
Yup, that should be it.

If you mean anything else to install, then no. Does charging work?

That is true. I have a Defy+ and I installed the CM9 kernel. It soft bricked my phone and I had to do a SBF flash, root CWM recovery and all things all over!! Flash the CM9 built for Defy+ by Quarx. It does restarts and freezes ocassionally but is okay otherwise for a beta version!!

[Q] do i have to install a gingerbread kernel before installimg cm9 defy+++ rom?

i have a defy + mb526 bl7 (rooted ). i want to install the defy+++ http://forum.xda-developers.com/showthread.php?t=1776161 rom.
bit in the thread it says for red lens version i need to install a gingerbread kernel before installing the defy+++ mod.
my confision is as far as i know the mb526 is a gingerbread device and runs on 2.3.6.
so do i need to install the gingerbread kernel?
i haven't installed any custom roms before so my qstn migjt be a little funny for u guys. please help.
No. Anyhow the latest CM9 ROM uses a 2nd boot kernel.

Jelly Bean camera

Hi, I root my defy+ and i have a little problem. When i'm trying to call somebody, my camera try to turn on (make that sound when i access the camera)
I have JB 4.1.2 Quarx 24.09
That is quite an old ROM. Newer ones have less bugs. Maybe you could try upgrading.

Defy+ ROM on Defy?

Can I flash the Defy XT or Defy+ ROM on my Green Lens Defy?
Someone link me?
yes you can use Defy+ roms on defy but only if it has 2nd boot.
Eg. MS2Ginger 5, CM10, CM9, Slim Bean, PAC, AOKP, Paranoid, etc.

So, no way to install the stock mb526 2.3.7 ROM?
Actually It's not urgent, as I've upgraded to an xperia Z, but my defy on CM 10 lags very very badly. Almost un-usable. So needed help :/
Don't ever try to install defy+'s stock 2.3.6 on Defy.
Read this http://forum.xda-developers.com/showthread.php?t=1216982
About SBF and CG version, if you install stock 2.3.6 on defy, you won't be able to revert back to 2.2 again, let alone many problem like camera won't work or battery stats malfunction.
If You want 2.3+ roms, use custom roms like those hackergnome suggested. (MS2Ginger was a modded stock 2.3.6 and can be used on MB525 without problem.)
Yes MS2 Ginger is the best gb rom in terms of stability!
