[Defy General] pedrosantos5:
I will tell you my point right now, i think will help you (i waste a lot of time to get this).

My Defy is standard M525 with red lens. Cames with Android 2.1 update1

Next i upgrade to Froyo 2.2.2 (it means i had froyo kernel)

Now i have Cyanogenmod 9 (CM9-NIGHTLY-120318-Defy+.zip) with

Model M526 (the Rom recognizes as M526 but i have M525)

Android vers. 4.0.3

Kernel 2.6.32.9 (GB Kernel)

If you have a Defy M525 (normal) Red lens (at least i have red, for green lens i don't have sure if is the same process) you have 2 options:

A. Upgrade from your froyo kernel to GB(Gingerbread ROM) with a NANDROID BACKUP and you are able to downgrade when you want to froyo again later.

or

B. Flash a full SBF 2.3.6 ROM rootable (DEFYPLUS_U3_4.5.1-134_DFP-139_VFBLUR_SIGN_SIGNED_USADEFYEMARAB1B8VFIT004.0R_PDS03C_USAJRDNGIBRVFIT_P022_A023_M004_HWp3_WIG148198_Service1FF.sbf)

This is a GB 2.3.6 ROM w/Blur multilanguage and rootable.

For this you can Wipe Data, with RSDlite5.6 connect you phone and on Bootloader mode flash the full SBF.

ATTENTION: After this if you want downgrade you need to read a lot but i guess it is possible (i will see better about)

For point A. you need:

1. Root your phone with SuperOne click 2.3

2. Install BootMenu with SndInitDefy_2.0.apk (i guess a reboot after root is necessary)

3. Copy a ICS Defy (CM9-NIGHTLY-120319-Defy.zip) to your SDcard

4. Copy CM7_Kernel-signed.zip, GAPPS (gapps-ics-20120317-signed.zip) and ICS Defy Red Lense Battery Fix_2.zip to SDcard

5. reboot (on blue led light press Vol - to enter in BootMenu)

6. go to Stable/Costume recovery

7. Wipe Cache and Data (before, you can do a Nandroid Backup (on BootMenu go to Backup and do it) so you can go back to your actual ROM later, optional)

8. Install Zip from SD

9. Select your ICS Defy and Flash

10. Flash CM7 Kernel (this is for who have froyo kernel, if you never did a full sbf flash of 2.3.3 or higher)

11. Flash Gapps zip

12. Wipe cache and wipe Dalvik Cache (on Recovery/Advanced)

13. You can flash the ICS Defy Red Lense Battery Fix_2.zip and when you have 100% of battery charge you should Wipe Battery Stats (on Advanced)

14. Reboot and its done!!!

For point B. you need:

After you Flash a full SBF 2.3.6 version YOU HAVE GB KERNEL, and you will do it:

1. Root your phone with SuperOne click 2.3

2. Install BootMenu with SndInitDefy_2.0.apk (i guess a reboot after root is necessary)

3. Copy a ICS Defy (CM9-NIGHTLY-120318-Defy+.zip) to your SDcard

4. Copy GAPPS (gapps-ics-20120317-signed.zip) to SDcard

5. reboot (on blue led light press Vol - to enter in BootMenu)

6. go to Stable/Costume recovery

7. Wipe Cache and Data (before, you can do a Nandroid Backup (on BootMenu go to Backup and do it) so you can go back to your actual ROM later, optional)

8. Install Zip from SD

9. Select your ICS Defy+ and Flash

AND ITS DONE, NO NEED ANY KERNEL FLASH because you already are on GB Kernel

11. Flash Gapps zip

12. Wipe cache and wipe Dalvik Cache (on Recovery/Advanced)

14. Reboot and its done!!!

You should install a battery calibrator and when you have 100% of battery charge you should Calibrate the Battery.

I have now the point B. done on my M525 and its 100%. I did it because when i realise, i did one full SBF flash of 2.3.4 (GB Kernel) so, after this i pick a 2.3.6 full SBF and flash and root and work's 100% and phone goes rooted.

I guess that's all!!!!
