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.
这个答案有帮助吗？
Yes! I contacted eBay sellers and found it out
