Hi Darius A reason for getting an “error 9” error while restoring is if the Lightning cable is not an original one from Apple. I read that you have used different cables, but if you haven't tried an original Apple cable maybe you should try that first. Other than that I don’t really know what could be the cause, but I know about a software on PC/Mac called ReiBoot that can enter and exit recovery mode on your iPhone when you connect it to your PC/Mac.
Hi Andi My first thoughts about this screen issue is that when you replaced your battery maybe your screen got damaged in some kind of way. For instance, when repairing iPhones the screen should not open more than 90° from the housing because this may stretch the flex cables. Another possibility is that the screen hasn't been connected properly. For the new screens you tried this may also be the case with those, but also if the screens are from third party manufactures they may not be as good quality and you have just been unlucky with two defect iPhone screens. If this isn't the case either then they may be problems with the connectors on the logic board or other components.
Hi Todd I have also had the same problem where I'm not able to screw some screws out because they´re to stuck or the screw is stripped. There is not to much to do about it than, in your case, to buy a new LCD Shield Plate for your iPhone 8. Only the original home button will work on your phone because it has the haptic feedback home button that is linked to only the iPhone it came with, so do not replace it with some other home button. Anyway, my suggestion is just to force the LCD shield plate out in some way for you to be able to remove the original home button. I found an iPhone 8 LCD Shield Plate on this website, and would assume that this isn't the only place where they sell these. (https://www.fixez.com/iphone-8-lcd-shield-plate) Hope this helps
The most common thing when getting Error 4013/4014 is a hardware issue. But in can also be caused by a faulty cable or port. I dont think the charging port or cable is at fault. You said that you checked the logic board in two different iPhones and it didn't work on the "bad iPhone". But then you took the "iCloud locked iPhone" logic board and put it into either phone and it worked. So the logic board is not ruined. I have a few things you can try out to fix the error/issue: 1. I see that you tried taking the face camera and proximity/flex cable off, but did you replace it? If you replace this it will maybe fix the error 4013/14. 2. There is something called the long screw damage. This is caused by screwing in the wrong sized screw to the EMI shield plate covering the cables connecting the screen to the device. This can cause a logic board damage. 3. If not this helped you can try this: -------------------------------------- 1. Connect to iTunes on PC or Mac in recovery mode, start recovery. 2.
