So i bought an iphone 3GS from craigslist today (been having really bad luck with iphones...) and it is stuck in recovery mode (the phone is in 10/10 condition it just will not get out of recovery mode) i have tried irecovery and DFU mode but it wont work. When i try to restore is gets to the very end, then reboots and says it failed due to error 1015. Please help! Thanks!!
