Unlike high-end Xiaomi devices that have dedicated EDL (Emergency Download Mode) authorization, budget devices like the mi a0101 rely on physical shortcuts to force the phone into a factory or preloader state.
A test point is a specific pair of copper contacts or exposed pads on the device's motherboard. When shorted with a conductive tool (like tweezers or a wire) while connecting the phone to a PC, it forces the device’s processor to enter Qualcomm HS-USB QDLoader 9008 mode (EDL mode) or MediaTek Preloader Mode, depending on the chipset. mi a0101 test point new
