Hi, got this iPhone 6 Plus off eBay. It was stuck in a boot loop. I don’t know the history but it gives error 9 in Itunes. I opened it up and since there were scratches on the metal brackets I assume it had been opened before. I think the screen might have been replaced but not sure. The casing has scratches and discoloration at the corners but no dents. Screen is immaculate and that’s why I am assuming it was replaced. The long screw looked in the right place. I tried restoring with the screen disconnected and then with the camera as well disconnected and same error. Thought I’d ask on here if it’s worth replacing the lightning connector or if anyone knows what it might be that’s causing this error. I don’t understand how it could be the NAND when Apple talks about USB connection issues regarding this error. I tried all the various Reiboot, Recboot and so on and they don’t work. If anyone could help me, I’d be very grateful. If it can’t be fixed very cheaply, I’ll just sell it on for parts. P.S. I tried the restore on a Windows laptop and a brand new MacBook and same error on both and the USB cable is not faulty either.

Error 9 emmc nand flash issue. Failure to flash to memory. It will be either a short in the pp1v8 /pp1v8 SDRAM or nand failure. Look for a technician that can write Thu underlying data to a new nand serial number WiFi and Bluetooth address and region this will solve the problem
