Dear All Good Evening,

I have green lense defy (MB 525). Accidently I have flashed defy plus full sbf ( probably non downgradable ). I have tried many 2.2 Froyo SBF roms but all nothing has been worked out for me. Now my defy is on sbf of defy plus in which Camera is not working, Although I am able to root BL 7 & I am on CM9. Is their any hope to either BL7 based froyo sbf or any method to downgrade from BL7.

Please Help.... And Best of Luck ....:good:

Try latest CMX with custom kernel - that may solve the camera problem. Battery charging is working for you?

It was astonishing for me, because I always thought, without changing the Kernel we never would be able to recognize the green lense. But with this CUSTOM ROM I can use my kamera like nothing happened. When you flash this Rom through CWM, be patient, when you reboot after flashing. It needs a long time to finish first booting. Just wait until you can see the regular Welcome screen.
Link to the Rom:

Greetings from joma227 with DEFY 525 green lense and full flashed with dfp231 (BL7). I dont need downgrade any more.
Thanks a lot to Quarx.:laugh:

Oh my GOD!!!! This is great news , i am amongst thousand others who committed the same mistake of flashing a MB526 rom on MB525 green lens phone and the end result a non working camera . I hope this works for me.

i made the same mistake and have bl7 on my green lense defy. unfortunately, when ein try to install quarks rom cm10 for 525 or also 526, after the update the defy only boots to the red m, not showing any animations after that an d freezing. i can reach the standard motorola boot recovery (by pressing volume down), but it doesn't reach the blue led for the custom recovery.

any ideas or tips?

Reflash stock bl7 sbf and rooted bl7 sbf. You can't downgrade due to eFuse which prevents you downgrading bootloaders. Then install Defy 2nd init 2.3 (latest version) and put Quarx CM 10 on the root of sd card.
