iPhone 7 BB CPU itself shorted
Has anyone had any Iphone 7 BB CPU shorted yet? I have done several 4013 and -1 repairs on these and recently took in 2 phones from a shop in Florida where I had a short on BBPMU_TO_PMU_AMUX1 and PP_1V0_LDO9 on one phone and just PP_1V0_LDO9 on the other. After removing the BB CPU the shorts went away on both, so I reballed and placed it back and shorts came back. Thinking I just made a mistake, I reballed both again and shorts came back a second time. I then checked those lines on the BB CPU and sure enough they are shorted within the BB CPU itself.
1. Has anyone else experienced this ...
2. I have NAND Programmer(s) but nothing for BB CPU... Is it even possible? Or does anyone have a programmer to reprogram new IC's?
Is this a good question?
