Lineage Power Driver

Posted on  by



Here’s my build of LineageOS 17.1 for Raspberry Pi 4 Model B, Pi 400, and Compute Module 4. It is unofficial and unsupported by the LineageOS team. It’s for advanced users only. Pi 4 model with at least 2GB of RAM is required to run this build.

The very popular Lineage OS 18.1 based on Android 11 has been released for Motorola Moto G7 Power (codename: ocean) as an unofficial build. Lineage OS 18.1 is an upgraded version of Lineage OS 18 with some performance and security enhancements. In this tutorial i am going to show you step by step tutorial of how you can install lineage os on any android device. As of now the number of devices are fe.

How to install:

  1. Follow the official Raspberry Pi instructions for writing the image to the SD card (Linux, Mac, Windows).

FAQ:

Q: How to enable developer options?
A: Settings -> About tablet -> Click ‘Build number’ several times. You need to ‘drag’ the settings menu to reach the ‘About tablet’ section that is last on the list.

Q: How to enable root access?
A: You can enable root access under Settings -> System -> Developer options -> Root access. LineageOS no longer has built-in root management for applications. You should keep this option disabled at all times when you are not using an app that explicitly requires root access.

Q: How to enable local terminal application?
A: Settings -> System -> Developer options -> Local terminal

Q: How to enable advanced reboot options?
A: Settings -> System -> Developer options -> Advanced restart

Q: How to find several Raspberry Pi specific settings options?
A: Settings -> System -> Advanced settings Uscutter driver windows 10.

Power

Most options in this menu require you to reboot your device for the setting to take effect.

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. See this page under ‘Which values are valid for my monitor?’ to see how to check in Raspberry Pi OS which resolutions your display supports. 1920x1080 resolution is used by default with this build. You can try changing value in /boot/resolution.txt to use a different resolution that your display supports. Removing /boot/resolution.txt will try to use the preferred resolution for your display.

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: I have official 7” LCD display and touchscreen. What should I do?
A: Official 7” touchscreen is only supported using SwiftShader software renderer. See below how to switch between different graphics drivers. You will also need to change display size under Settings -> Display -> Display size (or change ro.sf.lcd_density to 120 in /vendor/build.prop) to adapt to the smaller resolution.

Q: I need to use SwiftShader software renderer to use the official 7” display or I want to boot without any display connected. What should I do?
A: Warning, SwiftShader is a software renderer and using it affects graphics performance. You can switch between MESA and SwiftShader graphics drivers using a settings option found in Settings -> System -> Advanced settings -> Graphics drivers.

Also the previous method of executing following commands in ‘adb shell’/serial console/terminal still works:

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 -> Advanced settings -> Power button.

Also the previous method of executing following commands in ‘adb shell’/serial console/terminal still works:

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 3.5mm jack?
A: You can enable the feature by using a settings option found in Settings -> System -> Advanced settings -> Audio device.

Also the previous method of executing following commands in ‘adb shell’/serial console/terminal still works:

Q: How to use IR remote?
A: You can enable the feature by using a settings option found in Settings -> System -> Advanced settings -> Infrared remote.

You can place a keymap for your remote as /boot/rc_keymap to be automatically loaded on boot (see available keymaps for reference).

Q: How to use RTC?
A: You can enable the feature by using a settings option found in Settings -> System -> Advanced 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:

Q: How to use SSH?
A: You can start/stop the built-in SSH server by using a settings option found in Settings -> System -> Advanced 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.

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.

  1. Install EEPROM that supports booting from USB
  2. Write image to your USB device as above
  3. Mount the USB device on your computer and make following changes to /boot/config.txt under ‘Boot device’ section:
  4. 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.

Also the previous method of executing following commands in ‘adb shell’/serial console/terminal still works:

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: How to update from previous LineageOS 17.1 build without losing data?
A:

  1. Boot to TWRP recovery with the build you want to keep the data (see FAQ)
  2. Plug in an external USB storage device and select ‘Backup’
  3. Use ‘Select Storage’ to choose the USB device and ‘Swipe to backup’ (it’s only necessary to backup the data partition so you can uncheck other partitions to speed up the process)
  4. Write new LineageOS 17.1 image to the sdcard following installation instructions
  5. Boot to TWRP recovery with the new build (see FAQ)
  6. Select ‘Restore’ and find the backup you created from the USB device (‘Select Storage’)
