I found the forum while looking for a way to mod my Xperia PLay r800x. It's proven to be quite a pain in my arse. So far I've unlocked it via ZergRush, and I've had the bootloader unlocked by alejandrissimo, but I'm having difficulties getting fastboot to recognize my device at all. If any one could point me towards threads/users that can give me some pointers I'd be eternally greatful. Cheers!
