so i bought my iphone as 1.02 then revirginized and updated to 1.1.1, both unlocked. then i installed some package that made it keep restarting so i clicked update to 1.1.2 because that is the only thing that would get it to stop. then i downgraded firmware to 1.02 with the 1.1.1 baseband. i want to upgrade to 1.1.1 but every time i try it has an error 1015 and will not exit recovery mode. i could use it as an unlocked 1.02 but i want it to update to 1.1.1. any suggestions?
