1. Check your prerequisites on your computer

[ ] adb and fastboot are installed?
[ ] you have downloaded bootimage (img) and LineageOS (zip)?
[ ] you have the unlock code (in case of Fairphone 3)?
[ ] you have a usb cable prepared?
[ ] you are prepared to erase all the data on your fairphone?

2. Unlock your fairphone

Unlocking will allow us to overwrite the boot-loader.

  2. Press 7 times “Build number” to enable Developer mode
  3. Navigate to "Settings - System – Advanced – Developer options"
  4. Enable OEM unlocking with unlock your code
  5. Navigate to "Settings - System – Advanced – Developer options"
