Before connecting the phone, install the Spreadtrum USB drivers on your PC. Reboot your PC afterward.
To put the Huawei MediaPad T3 7 (BG2-U01) into EDL or Download Mode using test points, you must physically bridge specific pads on the motherboard while connecting it to a PC. This is typically used for bypassing FRP (Google Lock) or unbricking when software methods fail. Preparation
Tools: Precision tweezers (metal) and a high-quality Micro-USB cable.
PC Setup: Install the Spreadtrum (SPD) Drivers since the BG2-U01 uses the SC7731G chipset.
Safety: Power off the device and disconnect the battery cable from the motherboard before starting. Test Point Location
The test points are located on the rear of the motherboard, usually near the CPU/EMMC shielding or the battery connector. Remove the back cover carefully using a plastic pry tool. huawei bg2-u01 test point
Locate the pads: Look for two small, gold-colored circular pads close together.
The specific pads: For the BG2-U01 (SPD version), the test point is often a single pad that needs to be shorted to Ground (any metal shielding on the board). Step-by-Step Guide Open Device Manager on your PC to monitor the connection.
Short the Test Point: Use your tweezers to bridge the two test point pads (or the single pad to Ground).
Connect USB: While holding the short, plug the Micro-USB cable into the tablet and then into your PC.
Verify Connection: Look for a new entry in Device Manager under Ports (COM & LPT) titled SPRD U2S Diag or SPD VCOM. Before connecting the phone, install the Spreadtrum USB
Release the Short: Once the PC recognizes the device, you can remove the tweezers. Common Uses for BG2-U01 Test Point
FRP Bypass: Using tools like Octoplus Huawei Tool, SigmaKey, or Ultimate FRP Tool (UMT).
Flashing Firmware: Writing a new Stock Firmware or scatter file when the device is stuck in a boot loop. MediaPad T3 7 (BG2 U01) FastBoot SPD Chipset
A test point is a specific pair of裸露的 copper contacts on the phone’s motherboard. Shorting these points (using tweezers or a wire) while connecting the USB cable interrupts the normal boot sequence and forces the MediaTek processor into a low-level download mode.
Why do you need it for the BG2-U01?
On many Huawei/Honor devices utilizing similar chipsets to the BG2-U01, the test point is often located under a shield near the camera module or the SIM card slot area.
Look for a small copper pad or a tiny gold dot on the PCB (Printed Circuit Board). It is usually labeled in schematic diagrams, but on the physical board, it looks like a bare contact meant to be shorted to "GND" (Ground).
Typical Configuration: The test point usually requires you to short a specific point to the metal chassis (Ground) or to another adjacent point.
