I bought this nexus one used from someone on craigslist. It came with android 2.2. on it. frf 50 build and 4.04 radio. The video camera doe not work and I've researched and learned its due to the out dated radio. I received the ota frf91 update today but it didn't work. I have no idea how to fast-boot, update or upgrade my nexus one. i just want my video camera working and the lasted frf build, can someone please advise? my bootloader is unlocked
