If you see "QUSB_BULK" or "900E," the short failed. You are not in exclusive mode. Retry the pressure and angle of the tweezers.
If a root attempt goes wrong and the device is stuck in a Qualcomm Crashdump mode or a black screen (QUSB_BULK), the software is dead. The A0101 hardware point is the only way to wake the CPU for a fresh flash.
Normally, you enter EDL using a fastboot command (fastboot oem edl). However, if the bootloader is locked or the system partition is corrupt, that command fails. Shorting the test point physically bypasses the boot ROM and forces the processor to wait for a flash command over USB. The "A0101 exclusive" point is the only physical bridge that achieves this on specific Xiaomi boards.

If you want, I can:
This is where standard EDL fails. Because you are using the MI A0101 exclusive method, the firehose programmer required is unique.
Using MiFlash Pro:
When successful, you will see the progress bar move from sahara to hello packet to programming.
Cause: The battery is completely depleted, or the short is intermittent. Fix: Solder a thin jumper wire to the test points so you don't have to hold tweezers manually. Use a bench power supply to feed the battery connector 3.7V during the flash.
The MI-A0101 test point refers to a specific set of exposed copper pads on a PCB (typically a Xiaomi or Redmi motherboard) that allow forced entry into Emergency Download (EDL) Mode without software authorization. The term “exclusive” implies that this particular test point configuration is not shared with other device models and requires precise identification. If you see "QUSB_BULK" or "900E," the short failed
Purpose:
Bypass boot issues, lock states, or authentication to flash firmware via Qualcomm’s 9008 (EDL) interface.
By following this guide, you can reliably enter EDL mode on the Mi A0101 using the exclusive test‑point method, enabling firmware restoration or bootloader unlocking without additional hardware.
