Huawei — Test Point Driver

Take a pair of metal tweezers. Place one tip firmly on the designated test point dot and the other tip on a nearby metal shield or ground plate.

Widely used for flashing factory board firmware, repairing IMEI numbers, and removing locks on Kirin chipsets.

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.
