When a device is hard-bricked, the preloader file is corrupted, preventing the phone from booting or communicating with standard flashing software. By physically shorting the exclusive to the ground (GND) of the motherboard, you force the MediaTek bootrom (BROM) to intercept the USB connection before loading any corrupted system files. This opens a direct communication channel between the PC and the device's eMMC/UFS storage chip. When is the LG K52 Test Point Required?
