i have iphone 7 stuck on itunes logo try to restore dfu mode tried many time every time giving code error 4013 need some help with how to fix this issue thanks
I had a device with the same problem. The only way I fixed it was replacing the NAND chip. 4013 is related to some pretty major-ish parts of the phone, the only way to narrow it down is to get a multimeter and test capacitors and see if there is a short on some lines. If you can’t micro solder or don’t have any tools, I’d send it to some pro’s that are here on this website most of the big guys are able to mail-in repairs. Hope you find success with this phone!
