Okay the title explains it all, it's jailbroken ios 6.1.2 with envasi0n by envad3rs. I was texting on the texting app then all the sudden it froze, I tired hard restating it but it didn't work, then the screen dimmed, turned completely purple then white screened. I've tried DFU Mode & hard resetting it, I've also seen that thE LCD can be bad. Any suggestions?? I need help ASAP! Thanks!
