A test point is a small, exposed hardware contact on a smartphone’s printed circuit board (PCB).

The is an essential tool for technicians and advanced users looking to flash, unlock, or repair Huawei devices . When a Huawei phone is hard-bricked, in a boot loop, or has a locked bootloader, conventional software methods fail. In these situations, the "test point" method—which involves bridging a physical point on the motherboard to the ground—forces the device into USB COM 1.0 mode (similar to Qualcomm's EDL mode), allowing flashing tools to communicate with the phone's processor.

The phone's battery should be disconnected during the initial shorting process to prevent electrical shorts. The Execution Process
