Installation
- Follow the Installation guide
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: 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 and buttons
- lk2nd Fastboot: Power on the device. After it vibrates, hold
- Recovery: Power on the device with both and 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: 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.
