Hi I can’t seem to find the right answer I am trying to restore an old 6s but each time I do it’s like almost done it says “error -1 or 4013 . Or it says phone could not be found I tried 3 computers and different cords and different usb spots need any help
If I remember correctly the fix for this is to remove the baseband chip and make jumpers for certain pads. Then the chip would need to be reballed by a stencil and put back onto the logic board. 4013 can sometimes be the NAND needing reprogramming and/or replacement using ipbox or naviplus pro 300. -1 is for baseband like I said above. Both of these fixes require microsoldering.
