Installation

Note Warning: Flashing lk2nd is required, as it is a hard dependency. Without it the mainline kernel will not select the display panel (resulting in black screen on boot).
$ pmbootstrap install
$ pmbootstrap flasher flash_lk2nd
$ pmbootstrap flasher flash_rootfs

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