jailbreaked IP4 death, it does have and charge only 17% of battery enough for star, but it won’t charge more than that. i have replaced battery and same deal also i get another battery and same deal don’t want to charge more than 17-20% of capacity, also i have tried to reset to factory device, but t’ links for doing that are all fade and don’t work at all so i suspect that att kill my device because i have unlimited data and i was excessive using tethering with my iPad . WHAT DO YOU THINK? IT’S that POSSIBLE ? and the genius guys and apple don’t even give me an possible reason and just offer me tp replace my device for some money of course . someone there can beat this guys and help to recover my device from death.

DFU mode and restore through iTunes. This will get rid of jailbreak but its the only way to fix your phone. If that doesn’t work your out of luck and need a new phone.
