iPhone 6 A8 processor broken! Here is the best fix!

The iPhone 6 A8 CPU processor is broken after water damaged. Are you worried about that? Please don't worry, you can get the best fix here.

Disassemble the iPhone 6, we found the UMT board, which is not connected with 80mA, reset to measure is only 0.8V, it's not short circuit. After removing the iPhone USB control IC (U1700), iPhone display touch IC (U1501) and replacing PMU, the result is same, resistance value is also normal. When the CPU is removed, the reset value is normal 1.8, the value is lower again after installing reset voltage, now, the iPhone CPU fault is determined. The reset pullup resistance R0206 is 100K, and the voltage becomes 1.6V after the change of the 2.2K resistance.

The upper cover current is a little higher, and the iPhone screen is not displayed when install to test the iPhone 6 device. The DC power supply required for the measurement screen is normal, connect Ace assistant which shows "please unlock the device", so it indicates that the system has been entered, and the failure is from CPU. Then PP1V0 is measured short circuit, a few points on CPU are all short circuited. Now, we have to install the CPU back.

Directly connect 1.0V to this point, the current is 350A and the voltage is 0.8V. It seems hopeful, so we connect it with PP1V2_SDRAM directly.

Install the iPhone, and then test it, the iPhone 6 screen can be turned on now. Enter the IOS, test other functions, all is fine, the iPhone has been repaired!
