Understanding the JMM-AL10 test point is essential for technicians and enthusiasts working with the Huawei Enjoy 7s. When a device becomes software-bricked, stuck in a boot loop, or locked out of its FRP (Factory Reset Protection) account, standard USB debugging often fails. The test point provides a hardware-level bypass to force the device into a state where it can communicate directly with flashing software. What is the JMM-AL10 Test Point?

The JMM-AL10 is the specific model number for the Chinese variant of the Huawei Enjoy 7s. The "test point" refers to two specific metal contacts on the phone's internal motherboard. By shorting these two points—connecting them with a conductive tool like tweezers—you trigger the Emergency Download Mode (EDL) or Huawei USB COM 1.0 mode.

This mode allows the Kirin 659 chipset to accept commands from a computer even if the Android OS is completely corrupted. Why Use the Test Point?

FRP Bypass: Removing Google or Huawei account locks when you’ve forgotten the credentials.

Unbricking: Fixing devices that show no signs of life or won't enter Fastboot mode.

Firmware Flashing: Installing stock ROMs when the standard recovery method is unavailable.

Bootloader Operations: Performing low-level modifications that require COM 1.0 access. Prerequisites for the Procedure

Procedure for Using Test Points

To access the test points, the device must be partially disassembled:

---

The Huawei JMM-AL10 is powered by a MediaTek (MTK) processor (specifically the MT6737T). MediaTek-based devices are notorious for requiring test points to enter "BROM Mode" (BootROM mode) when the device is bricked.

For the JMM-AL10, the test point is not a single pin but usually a pair of pads that need to be shorted together. These pads are connected to specific lines (e.g., KCOL0 or a voltage pin) that trigger the CPU to wait for a bootloader handshake over USB.

Before resorting to hardware manipulation, consider these alternatives for the JMM-AL10:

However, for a hard-bricked device, no alternative exists – the test point is the only solution.

---

Position varies by model and board revision; typically a pair of exposed pads near the battery connector or on the mainboard edge. On the JMM-AL10 PCB it’s often labeled “TP” or a test-signal name and may require disassembly to access.

Connect USB: While maintaining the short, plug the USB cable into the phone.

Release the Short: After 2-3 seconds, release the tweezers.

Check PC Detection: The PC should now detect the device as “Huawei USB COM 1.0” (or a COM port number). In IDT, the port should turn yellow.

Start Flashing: Click “Start” in IDT. The tool will write the Bootloader, Boot, Recovery, System, and Cust partitions.

Note: Some JMM-AL10 units use a MediaTek chipset. If your PC detects "MTK USB Port" when shorting, use this method.
