How to enter flash mode

  • Stock Fastboot: Power on the device with both Power and Volume Down buttons
  • lk2nd Fastboot: Power on the device. After it vibrates, hold Volume Down
Note Note: Pressing the keys too early will cause the stock bootloader to handle the key combination. You will end up in the wrong Fastboot interface.
