Installation

Note Note: lk2nd is a hard dependency, without it the mainline kernel will not select the panel.
$ pmbootstrap install
$ pmbootstrap flasher flash_lk2nd
$ pmbootstrap flasher flash_rootfs

How to enter flash mode

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

Modem

Modem works with work in progress IPA patches 6.7.0/main, you have to compile kernel yourself and enable CONFIG_QCOM_IPA2_LITE.

Note Note: Mobile data, SMS and Calls are working, but there's no sound from microphone and speaker.

GPU

Works but with some glitches. No known workaround.
