How to enter flash mode

  • Fastboot: Power on the device with both Power and Volume Down buttons.
  • Recovery: Power on the device with both Power and Volume Up buttons.

EDL Mode

Note Note: An authenticated Mi account for EDL flashing is required.

To enter the EDL mode, disconnect the battery and short these two points while powering it on with USB. If lsusb -d 05c6:9008 shows you a device, you can let go of the short.

UART

Note Note: According to the schematics this is where UART should be, however there is no output on the TX point. Only 1.8V is being measured on TX.

The UART points are located on the front on the mainboard, so thin wires should be soldered to the tiny test points to route them to the back.
