Installation

Fastboot Mode

First make sure to enable USB debugging in Android ([1]) Then with device powered off, hold the Volume Down and Power buttons simultaneously for a few seconds, until Fastboot Mode screen appears.

OEM Unlock

Get device into Fastboot Mode, plug in USB cable, then:

$ sudo fastboot oem unlock

When prompted on device, use Volume-Up/Down buttons to highlight choice, then Power button to select it. The Fastboot Mode screen will appear again, and a message saying that the device isn't secure will appear briefly.

Installation

Build the image

$ pmbootstrap init
$ pmbootstrap install

Mi A2 Lite (xiaomi-daisy)

In order to use the daisy, installing lk2nd is needed. The package lk2nd-msm8953 provides a prebuilt version ready to flash to the device.

To use it, add it in the init step or instead of running pmbootstrap install, add the package like this: pmbootstrap install --add lk2nd-msm8953

Then put the device in fastboot mode and run:

$ pmbootstrap flasher flash_lk2nd

Then reboot the device and press the Volume Down just after the Android logo shows up and hold until the device vibrates and shows START in green at the top left corner of the screen.

Redmi 6 Pro (xiaomi-sakura)

In order to use the sakura, installing lk2nd is needed. There is no prebuilt version of lk2nd for sakura you need to build yourself.

Redmi 6 Pro has rollback protection for lk2nd installation first you need

$ fastboot boot lk2nd.img

then

$ fastboot flash lk2nd lk2nd.img

Install the image

To proceed with the installation to internal storage of pmOS, plug the device to the computer with an USB cable and run:

$ pmbootstrap flasher flash_rootfs --partition userdata
$ sudo fastboot format system
Note If you want to install pmOS to an SD card instead of internal storage, you need to add --sdcard <device path> at the end of the install command.
I.e. (using lk2nd): pmbootstrap install --add msm8953-lkn2d --sdcard /dev/<your_sdcard>

Mainline Kernel

To use it select mainline kernel when running pmbootstrap init

Flashing lk2nd is needed. ([2]).

Feature table

Parts Status Notes
Modem Partial ModemManager needs to see a mobile data device, so IPA support is half-needed for calls and SMS to work. There's partial support for it in a dev branch, the driver probes and configures everything, but mobile data still doesn't work.
WiFi Works
Sensors Partial Working with i2c-gpio from here, still missing a proper SSC driver
GPU Works
Audio Works Everything works. Speaker works since version 6.4.7. Needs alsa UCM config from this package.
Touchscreen Partial Only Focaltech models supported. Models with Goodix GT917D chip not working yet.
Charger Works Driver added in 6.1
Panel Partial Only supported hx8933, ili8707 and otm1911 models (not sure if there are any other panels)

Modem

Firmware loads and modem boots. It detects SIM card and can be unlocked and configured with qmicli.

Because audio needs more work i couldn't test audio quality on calls but with q6voiced it should work.

Mobile data

Note Mobile data is not working in kernel version 5.15 and later. There's an ongoing effort to upstream the driver needed for mobile data to work. A testing branch can be found here.

Mobile data works now.

To configure the mobile network settings, use NetworkManger (mobile network menu on phosh settings) so it sets up the network interface and IP routing.

After that, two new network interfaces should appear. The rmnet one is the connection to the modem, and the other one is virtual and the one that is used to transmit mobile data.
