I bought a brand new iPhone 5s with iOS 7.1.2. I jailbroke it, added iCleaner, and Hiddensettings7. A week later I noticed the display was not coming on. I clicked the home button, could hear the screen shots being taken etc. I plugged in the charger and the display flickered them came on. Two days later the same thing happned. The display was off and I tried everything. I rebooted the phone, I restored from back up. I don't want to update the phone to iOS 8. Anyways nothing worked. I never experienced this issue ever. The phone is sitting here useless. What can I do?
