So I bought an iPhone off from Ebay. It said it was unlocked. Added it to my T-mobile account. Worked great. I made ONE phone call, had it less than one hour when my 14 year old son decided to update the OS to sync it with his iPad (or something, IDK). Anyway, it wouldn't let him update it, then went to restore but when it gets to the end of restoring it says it can't be restored because of a 1015 error. I contacted the seller and come to find it wasn't unlocked from Apple, he had it done with some kind of software (IDK which one). After doing some google searching I realized it won't update because the phone was "hacked" (according to Apple). The Apple Store won't help me because it's "hacked". I've tried to use Tiny Umbrella to kick it out of restore, but even though I can see the exit restore button it's not lit up for me to click on. All I get when I turn the phone on is a USB cord pointing towards a iTunes logo. I've tried for hours, but nothing has worked. I am fairly useful around a PC, but I know nothing about Apple. It's like a foreign language to me. No one around me fixes them either. I'm about ready to kill my son! Please help me! I need someone to explain it to me in the simplest terms possible because I don't have any idea what I'm doing. THANKS IN ADVANCE (and my son surely thanks you too!)
