motherboard. These exclusive test points are positioned adjacent to the main processor shield and the board's expansion sectors. They consist of two tiny, identical golden circular pads placed millimeters apart. Flashing Execution via the Test Point
While maintaining the physical bridge with your tweezers, insert your USB cable directly into the tablet's port and connect it to a high-speed port on your PC.
A test point serves as a direct hardware interface to the device's boot ROM (Read-Only Memory). When the device is powered on normally, the boot ROM loads the primary bootloader. However, by manually connecting (or "shorting") two specific test points together while connecting the device to a computer, the boot ROM is forced to bypass standard booting procedures and enter a special, low-level state. As one technical guide notes, these two physical points force the device to run in a specific engineering mode.

Reattach the internal battery flex cable securely to the motherboard connector.
Flashing official firmware directly when the bootloader is locked.

However, it demands authorized firehose programmers and carries serious anti‑rollback and security risks. Flashing Execution via the Test Point While maintaining
For the repair technician, memorizing the A0101 test point layout is like a locksmith knowing how to pick a Medeco lock—it’s niche, risky, but when a client's device is a paperweight, you are the only one who can bring it back to life.
