I have an iPhone 5s that I cant restore (error 4013), Ive tried DFU mode and everything. It just loops the apple logo and flashes a red screen in between sometimes. Losing data is not a concern I just need to get this phone working all help greatfully received!
Try unplugging the front camera cable and try restoring the phone again. It’s a common cause of red screen of death issue.
Same issue with me… people are saying it could be long screw damage. When you put the wrong screw in the wrong spot, it could damage the logic board.
This is a super helpful response I got from @refectio. Credit to them for this great response!! (hopefully they don’t mind that I’m adding this!)
