How to install:
- Follow the official Raspberry Pi instructions for writing the image to the SD card.
If you’re running a recent build (20220114 or newer) you can also update to newer builds using TWRP flashable OTA packages. OTA updates pushed through the built-in Updater app are stored at /data/lineageos_updates/.
- Download lineage-19.1-xxxxxxxx-UNOFFICIAL-KonstaKANG-rpi4-ota.zip and save it to your device’s internal storage or use an external USB drive
- Boot to TWRP recovery (see FAQ)
- Install lineage-19.1-xxxxxxxx-UNOFFICIAL-KonstaKANG-rpi4-ota.zip from your selected storage
- (Flash Magisk/other add-ons you had previously installed)
- Boot out of recovery (see FAQ)
Changes that are backed up and restored flashing OTAs:
- Device specific settings changed using Settings -> System -> Raspberry Pi settings
- Manual changes to /boot/resolution.txt and /boot/rc_keymap.txt
- USB boot configuration in /boot/config.txt
Changes that are not backed up and restored flashing OTAs:
- Manual changes to /boot/config.txt (and any other manual changes to /boot partition)
Q: How to find several Raspberry Pi specific settings options?
A: Settings -> System -> Raspberry Pi settings
Most options in this menu require you to reboot your device for the setting to take effect.
Q: How to enable advanced reboot options?
A: Settings -> System -> Buttons -> Power menu -> Advanced restart
Q: How to enable developer options?
A: Settings -> About tablet -> Click ‘Build number’ several times.
Q: How to enable root access?
A: LineageOS no longer has built-in root management for applications. You can have root access via ADB after enabling Settings -> System -> Developer options -> Rooted debugging, SSH (see FAQ below), or serial console. It is also possible to install Magisk following instructions later in the FAQ.
Q: My display is not working. I can only see the rainbow screen but no Android boot animation. What should I do?
A: This build only supports HDMI displays that report supported resolutions using EDID. 1920x1080 resolution is used by default with this build. You can change value in /boot/resolution.txt to use a different resolution that your display supports. Removing /boot/resolution.txt will use the preferred resolution of your display.
Q: How to use official 7” touchscreen display?
A: You can enable required configurations using a settings option found in Settings -> System -> Raspberry Pi settings -> Touchscreen.
Q: Settings -> Storage shows total system size of 7 GB. There’s unallocated space on my sdcard. What should I do?
A: This is a 7 GB image, remaining space on your sdcard will remain unallocated. Easiest way to extend /data partition is to simply flash my resize zip in TWRP.
Alternative option is to use e.g. GParted and extend /data partition (/dev/block/mmcblk0p4) to cover the unallocated space. Resizing the partition manually will break support for encrypting /data. Format /data in TWRP recovery (Wipe -> Format data) after resizing to leave required space for crypto footer.
Q: Raspberry Pi doesn’t have a power button. How to power off/reboot device?
A: Following keyboard keys work as Android buttons: F1 = Home, F2 = Back, F3 = Multi-tasking, F4 = Menu, F5 = Power, F11 = Volume down, and F12 = Volume up. You can also use one of many third party reboot applications.
Q: How to create a DIY hardware power button?
A: You can send power button events by connecting GPIO21 to ground.
You can enable the feature by using a settings option found in Settings -> System -> Raspberry Pi settings -> Power button.
You can also use the DIY power button to boot the device to TWRP recovery. Press and hold the button while powering on the device until you see the TWRP screen.
Q: How to enable audio through HDMI?
A: 3.5mm jack is used for audio by default. You can select the audio device you want to use by using a settings option found in Settings -> System -> Raspberry Pi settings -> Audio device.
Q: How to use IR remote?
A: You can enable the feature by using a settings option found in Settings -> System -> Raspberry Pi settings -> Infrared remote.
You can place a keymap for your remote as /boot/rc_keymap.txt to be automatically loaded on boot. See available keymaps for reference. You can use
ir-keytable -p all -t in rooted shell to figure out the keycodes for the remote you’re using.
Q: How to use RTC?
A: You can enable the feature by using a settings option found in Settings -> System -> Raspberry Pi settings -> Real time clock.
System time is automatically read and set from the RTC on boot once you’ve enabled the feature. You need to write the system time you want to use to the RTC in rooted shell:
hwclock -w -f /dev/rtc0
Q: How to use SSH?
A: You can start/stop the built-in SSH server by using a settings option found in Settings -> System -> Raspberry Pi settings -> SSH.
Android doesn’t have user accounts with passwords so key based authentication is used with SSH instead. Necessary keys are generated on the first boot and you need to pull the private key to your computer (or alternatively you can push your own previously generated keys to the device). See Settings -> About tablet -> IP address for your device’s IP address (192.168.0.100 is assumed here). Enable Android debugging & Rooted debugging under Settings -> System -> Developer options.
adb connect 192.168.0.100 adb root adb pull /data/ssh/ssh_host_ed25519_key my_private_key
chmod 600 my_private_key ssh -i my_private_key email@example.com
It’s recommended to disable adb after this.
Q: How to boot from USB device?
A: Warning, this is still an experimental feature. Especially TWRP seems to have some issues with USB boot.
- Install EEPROM that supports booting from USB
- Write image to your USB device as above
- Mount the USB device on your computer and make following changes to /boot/config.txt under ‘Boot device’ section:
- Plug in the USB device to your Raspberry Pi, remove any sdcard, and boot
Q: How to boot to TWRP recovery?
A: You can boot to TWRP by selecting recovery option in Android power menu after enabling advanced restart options.
If mouse cursor doesn’t appear, try replugging your mouse.
Q: How to boot out of TWRP recovery?
A: You can boot out of recovery by simply selecting reboot to system option in TWRP.
Q: My device keeps booting into TWRP recovery. What should I do?
A: If you have GPIO21 connected to ground (or if you have something drawing power from it) your device will always boot to TWRP recovery (see FAQ section about DIY power button). If you have a hardware failure on GPIO21 you can edit /boot/config.txt to remove the GPIO21 related logic (see ‘Ramdisk’ and ‘Graphics acceleration’ sections).
Q: How to install Magisk?
- Download lineage-19.1-rpi-magisk-v25.2.zip and save it to your device’s internal storage or use an external USB drive
- Download Magisk-v25.2.apk
- Boot to TWRP recovery (see FAQ)
