My friend here at college jailbroke my iphone 6, 64g (sprint). It was great for a while and I had no issues.. When my screen cracked, it all went downhill. My phone started dying on about 25% so I went and tried to restart it which put me into a loop. I took some measures and tips online to get out of the loop.. Now im stuck in recovery mode. I neeeeeeed my phone. I tried to restore it through itunes and I get all types of errors. (usually error 51) I brought it to apple (not telling them it was jailbroken) and they said the reason i cant restore is because I replaced the phone screen... i need help!!!
