Hey everyone. so i have a iphone and it had been jailbroken from someone i bought it off of on craigslist. well one day i went to go update my software and then my phone would not turn on unless on charger, so after a day or two my phone cut off and then turned on but it had the itunes logo plus the cord pic. i tried to re-jailbreak it using greenposi0n but it would get half way thru the jailbreak and say done but it was stuck on the black screen with all the white words on it but you could tell it was not fully done. i then tried using snowbreeze v2.9.5 and restoring it but halfway through again it gave me error code 1600 which means it was in recovery mode and not dfu mode but i tried everything. i even called somone who had a bussiness fixing iphones but they said i need to hook the iphone up to the computer it was jailbroken on but i bought it off craigslist. then thought about just going to the apple store but it has a conversion kit and i know that they will turn it down. what should i do?? please someone help i need a phone!!
