iPhone 5s, error 40 after screen replacement.

iPhone 5s, error 40 after screen replacement.

I just changed the screen on my iPhone 5s. After I booted up I had no power. I plugged it into my PC and then opened iTunes. iTunes tells me that I needs to restore the phone, so naturally I do and when it gets to the "waiting for iPhone" it then quickly gives me the error 40 code. I don't know what to do, the screen also doesn't display anything properly, and by that I mean the apple logo, because its the only thing I get it to display(the phone turns on when this happens only when iTunes gets into the "waiting for iPhone" part).

Well I too had the same problem.... here is a temporary solution but still you will need to change your battery. You need to connect your iPhone 5s to iTunes in your Mac or PC and try restoring it for multiple times. I had done the same for almost 4-5 days and then it turned on. And keep it on charging at most times. Though it will turn on but still you will need to change your battery. ☺️''
