Upgraded to 3.3 last night. Didnt realize helmi's WM6 rom existed. now i want his rom but cant upgrade to it. Im getting different errors. ANd i try to downgrade to my old version and it wont let me do that either. It will say device is not connected when i try to downgrade to an older rom. And when i try to put the helmis wm6 rom on it tells me its not made to run on this device. Can anyone help me? I read somewhere that i needed to revert my bootloader to 2.2v and i did because it was 2.4 when i did the 3.3 upgrade. But now its back at 2.2v and none of the roms will work.
