@Kevin-jz9bg 3 жыл бұрын
You don't need to trace the motherboard, just search up a schematic of the iPhone you want to fix. Make a list of the 16 power lines, and then CTRL-F to find which parts of the board you can access them. (And of course, find a ground point as well.) Once you find the part on the schematic, find it again on the PCB layout. Hope this helps :)

@@peverellpoulin5087Most of the chips on an iPhone are interchangeable. But he CPU, the baseband CPU and the NAND will have to be from the same device since they are encrypted together. The NAND is a special case. With a NAND programmer, you can read, write, alter or transfer data from the NAND. But dimoly changing the info on the NAND will not work. All three, the CPU, the baseband and the NAND all need to have the same data.

Unprofessional! No need to break the shield to remove U2 and even tho no need to replace with the new one to see if it’s ok! Just remove it and turn it on if it’s the u2 then the device turns on and enters a loop, anyway you could realize the cpu issue by measuring the feedback line when it’s not connecting to the cpu right then fb line is 4V !
