iPhone 4s In Black Screen After Restore For few weeks now, i've been having series of problems with my iPhone 4s. I was Jailbroken on iOS 6.1.3. I had series of Screen Flickers, White Screen when trying to restart, Battery Problem, and couldn't even wipe it (It got stuck on Apple Logo for hours). So i had to restore it via iTunes hoping this issues will go. Now after puting the phone in Recovery Mode, i was able to restore to iOS 7.0.4. Now my phone wont show, pure black screen. But i hear it beeping when connected to iTunes. Cant put it in DFU Mode or Recovery Mode, because nothing is on display. I've tried Home/Sleep-WakeUp key hundreds of times. It just fades in and out. Nothing showing. iPhone is out of warranty. Nothing like Apple Office here in Nigeria. Most of the techy guys around here aint familiar with Apple Products, so am afraid to take it them. I'm stuck! Dunno what to do. Its still on Welcome Screen, not activated yet. (I know this because i've not done anything to it after the restore, so it's back to new). If you guys need me to post the phone logs obtained via "iTools", i can. Please help.
