Are you referring to the lowest debug, or the lowest retail firmware? I know that you can install debug 2.15 firmware, and retail 3.15. I would love to know what else is possible. ^_^
btw, be careful when flashing the debug files it will change your SHA1 hash encryption.
Sorry for the double-post, but for some reason I can't edit my last one.
If you do happen to flash to 2.15 debug firmware, I would love to know if your able to come back from it to a retail firmware. On behalf of myself, and i'm sure the rest of the scene, thank you for your contributions in testing. Its greatly appreciated!
