You need the correct USB drivers installed on your PC so that Windows can recognize your phone when it is in MediaTek pre‑loader (BROM) mode. The most reliable choice is the . Without them, the PC will either not detect the phone at all or will show a generic “unknown device” error.
The concept of a test point is universal and used across many smartphone brands, especially those with MediaTek or Qualcomm processors. For example, for the or Honor 7X (BND-AL10) models, the process is fundamentally the same, requiring you to open the device, locate the specific test point, and short it to ground. Other Huawei and Honor devices, like the Honor 10 (COL-AL10) or Huawei Nova (CAN-AL10) , also support this procedure. The main difference is the physical location of the test point on the PCB, which can vary significantly between models.
This process should only be used for legitimate device recovery (bypassing an FRP lock after forgetting your own credentials or unbricking a dead phone). jmmal10 test point upd
If your phone is already bricked and out of warranty, performing this procedure has little downside. With careful preparation—correct drivers, authentic firmware, and a clear image of the test points—you can turn a $0 paperweight back into a functioning smartphone.
Unlike Qualcomm devices that require an Emergency Download Mode (EDL 9008) test point, MediaTek platforms utilize an internal bootloader state known as BROM mode. When the operating system gets corrupted or locked out, software commands can no longer establish a secure communication bridge. Technicians must bypass the standard preloader initialization by physically grounding a tiny gold pad on the motherboard, known as a test point.

If you are stuck on any part of the procedure or need help finding the software for your specific firmware version, I can help you narrow it down.
Once you have the motherboard exposed, follow these steps with extreme caution to avoid damaging the device. Step 1: Prepare Your PC Software The concept of a test point is universal
The station’s OS was archaic, a labyrinth of code patches and jury-rigged updates that had accumulated over decades. The only way to manually reroute power from the dead mainframe to the life-support backup was through a service port buried deep in the sub-menu of a sub-menu.
