How to install:

  1. Follow the official Raspberry Pi instructions for writing the image to the SD card.

FAQ:

Q: I can’t find developer options, why?
A: Settings -> About tablet -> Click ‘Build number’ several times

Q: I have no root, why? What is that hashtag on my status bar?
A: You need enable root access under Settings -> System -> Developer options -> Root access. Root management is now integrated as part of LineageOS’ Privacy Guard and you can manage per app permissions under Settings -> System -> Developer options -> Manage root access. You’ll have a persistent notification in the status bar when you’re running an app that uses root permissions.

Q: Settings -> Storage shows total system size of 4 GB. There’s unallocated space on my sdcard. What should I do?
A: This is a 4 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: 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. 1280x720 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.

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 /system/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 by executing following commands in ‘adb shell’/serial console/terminal (you can enable built-in terminal app from Settings -> System -> Developer options -> Local terminal):

su
rpi3-graphics.sh swiftshader

su
rpi3-graphics.sh mesa

Q: Raspberry Pi doesn’t have power button, how do I power off/reboot my 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.

fritzing

Execute following commands in ‘adb shell’/serial console/terminal (you can enable built-in terminal app from Settings -> System -> Developer options -> Local terminal) to enable the feature and reboot your device:

su
rpi3-powerbutton.sh

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. If you use this method to boot to recovery, you can ignore what is said about booting into/out of TWRP later in the FAQ.

Q: How to enable audio through 3.5mm jack?
A: Execute following commands in ‘adb shell’/serial console/terminal (you can enable built-in terminal app from Settings -> System -> Developer options -> Local terminal) to enable the feature and reboot your device:

su
rpi3-audio-jack.sh

Q: How to boot from USB device?
A: Warning, this is an experimental feature and there’s still some issues with it. Android shows USB storage notification for each partition and you should ignore these. TWRP shows errors in few places but everything seems to be working regardless of this.

  1. Follow the official instructions on how to enable USB boot on Pi 3 B (this step is not needed on Pi 3 B+)
  2. Write image to your USB device as above
  3. Mount the USB device on your computer and rename following files on the boot partition: 
    mv ramdisk.img ramdisk-sdcard.img
mv ramdisk-usb.img ramdisk.img
mv ramdisk-recovery.img ramdisk-recovery-sdcard.img
mv ramdisk-recovery-usb.img ramdisk-recovery.img
  4. Plug in the USB device to your Raspberry Pi, remove any sdcard, and boot

Q: How to boot to TWRP recovery?
A: There’s currently no proper way to boot between Android and TWRP, but this can achieved by renaming the ramdisk you want to boot. Execute following commands in ‘adb shell’/serial console/terminal (you can enable built-in terminal app from Settings -> System -> Developer options -> Local terminal) and reboot your device:

su
rpi3-recovery.sh

If mouse cursor doesn’t appear, try replugging your mouse.

Q: How to boot out of TWRP recovery?
A: You can execute the same script in TWRP terminal (Advanced -> Terminal) if you have boot and system partitions mounted (Mount -> Boot & Mount -> System):

rpi3-recovery.sh boot

Or you can flash my recovery2boot zip 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 update from previous LineageOS 16.0 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 16.0 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’)
  7. Make sure you only have data selected as partitions to restore (uncheck other partitions if available) and select ‘Swipe to Restore’
  8. (Flash Google apps package/other add-ons you had previously installed)
  9. Boot out of recovery (see FAQ)

Q: How to install Google apps?
A: Warning, installing gapps slows things down especially on low-end devices with limited amount of RAM such as this one.

  1. Download open_gapps-arm-9.0-pico-xxxxxxxx.zip and save it to your device’s internal storage or use an external USB drive
  2. Boot to TWRP recovery (see FAQ)
  3. Install open_gapps-arm-9.0-pico-xxxxxxxx.zip from your selected storage
  4. Wipe -> Factory reset!
  5. Boot out of recovery (see FAQ)
