Hey guys, Super weird situation. My customer gave me an iPad Air to fix. The screen was super bad. When I opened it I found out that besides the screen one of his battery’s section was swollen, I replaced the screen and the battery. iPad was working fine until the battery died. When I came to him his iPad boot looped on apple logo. Now, when I am trying to restore it, the only thing I have is an error 4013. I tried everything. I change already 3 batteries, 3 computers and 5 cords. Noting seems to work. Any idea what is going on?
I suspect that the defective battery caused a corruption issue on the NAND. This requires removing the NAND, re-programming it and re-soldering it in place. All memory will be lost.
