Red screen of death
I have replaced the screen on an iPhone 5s. After replacement it couldn't boot up properly, I mean it stuck on the apple logo.
So I thought I could put it in DFU mode to restore it with iTunes. Once put in the DFU mode and connected to iTunes on a Mac, iTunes started to restore and downloaded the newest iOS. When it finished downloading it wrote "Waiting for iPhone". Ok thats normal.
But than accidentally on the phone appears a red screen. iTunes gives me an error 4013.
Thought it could be the front camera as I faced that problem in the past already with other iPhones, so I disconnected only the front camera, but still same error.
Is this a good question?
