Help Needed: Locate Test Point on BYD MTA-B01 (MT6765 - MediaTek) Head Unit Board
Hello everyone,
I'm currently working on dumping the firmware from a BYD Seagull car head unit (Model: MTA-B01). The unit is based on a MediaTek MT6765 (Helio P35) chipset. I am using MTKClient successfully on PC.
Unfortunately, the board does not have any buttons, and does not enter preloader mode automatically when powered via USB-C. I'm now looking for a Test Point (TP) that would allow me to force the device into Preloader or BROM mode.
I have disassembled the board and captured high-resolution photos of the main PCB from multiple angles. Below are the images:

(Attach the photos you've already taken)
Board markings:
DI2.1H-MCU-E22022.1.15💡 Has anyone worked on similar BYD units or MediaTek-based head units?
I’m looking for confirmation of which pad is the correct Test Point to short to ground (if any), or schematics / boardview files if available.
Thanks in advance to all developers and hardware engineers who can help!
