Software Installation

Android

The Feasible can run Omnirom for Raspberry Pi 4 or Konstakang's Android 11 for Raspberry Pi 4. These are the only two versions of LineageOS that are arranged for the Pi 4 that I am aware of. Other android distributions will probably work as well.

The sha256 sums of the versions that I have downloaded are part of the checksum database.

These instructions assume that Linux is installed on your computer.

Instructions

Questions specific to Konstakang's Android distribution can go here

Download the desired ROM any any other files that you want from the Omnirom website or Konstakang's website
Check the SHA256 sum if desired.
Unizp the downloaded file to produce a file whose name ends in ".img"
Insert your microSD card into the reader on your computer and determine which device has been assigned to the SD card.

Use the Linux utility dd, etcher, or any similar program to write the ".img" file to your SD card

Note that all data on your SD card will be destroyed.
Remove the microSD card from the reader and plug it back in. Let Linux mount the various partitions.
If using Konstakang's LineageOS Change to the directory where partition #1 from the microSD card is mounted and change the contents of resolution.txt to "1080x1920"

If using Omnirom I recommend disabling overclocking. Comment out the following lines in config.txt and config.txt.rom on the first partition of the microSD card.
over_voltage=2
arm_freq=1750
Unmount all of the microSD card partitions
Use gparted to resize partition #4 from the microSD card such that it fills all of the unoccupied space on the card except for 1 megabyte.
Transfer the microSD card to the Raspberry Pi and boot. You should get a screen that is part black & white static, and part color static. Then, Android should boot.
Consider installing Magisk to control root and microG to provide a Play services alternative.

Linux

Linux installation is easy. Just use the same process as is used for every other Raspberry Pi software installation.

I will base my instructions on Ubuntu Mate 20.04 for the Raspberry Pi.

Download a copy of the image from the Ubuntu Mate website. I recommend that you choose the arm64 version.
Decompress the archive
xz -d -v ubuntu-mate-20.04.1-desktop-arm64+raspi.img.xz
Insert your microSD card into the reader on your computer, and determine which device has been assigned to the SD card.

Use the Linux utility dd, etcher, or any similar program to write the ".img" file to your SD card

Note that all data on your SD card will be destroyed.
Transfer the microSD card to the Raspberry Pi and boot!
