Downgrade B/L 09.02 to 08.D0

**vinjamoor.venkatesh** · 07-13-2007, 07:15 AM

Hey,

Is there a step-by-step guide to do the above. I do know that it is very risky. But I think of trying it. I searched through the forum and couldnt find one. Can anyone give a correct link to the guide.

Regards,

yes, it can be done now that there is a patch to keep the firmware from checking the pds on boot, but you first have to change to the 08.d0 bootloader....

Guys, I have not login for several weeks and I know nothing about patch in firmware. My friends have boot loader 09.20 and want to mod his L7. So I have a few question needs to be explained:
1) what is the possible mod can be done to 09.20 without downgrade it?
2) what is the risk to downgrade to 08.D0? can it possibly bricked?
3) is there anyone who has succesfully downgrade to 08.D0 without doing PDS repair?
4) has that guy upload his MP or willing to do that?
your help is greatly appreciated guys.. thanks..

O8.D0 will only work for you if u can manage to downgrade your bootloader.
