1. Check your prerequisites on your computer

[ ] adb and fastboot are installed on your computer?
[ ] 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 have removed your screen lock?
[ ] your phone has at least 70% battery?

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 USB Debugging
5. In case of Fairphone3:

   2. Enable OEM unlocking with unlock your code

3. Connect via usb

For overwriting your fairphones boot-loader we will need connection to your pc.

1. Connect your computer & fairphone via usb
2. On your fairphone allow the usb connection
3. Type adb devices on your computer (in case of windows open the terminal in the directory containing adb&fastboot.exe and use the .\ prefix. The resulting command will be: .\adb devices).
   The result should show something like

   List of devices attached
   <SerialNumberOfYourPhone>	device
   

4. Prepare recovery image installation

The next step is the critical one. If this step goes wrong your fairphone may remain broken. Time to do some checks:

1. Check that your phone has at least 70% battery.
2. Reboot your fairphone to bootloader mode: Type adb reboot bootloader on your computer.
3. Fairphone should show the bootloader screen.
4. Type fastboot devices on your computer. The result should show something like

   <SerialNumberOfYourPhone>	fastboot
   

5. Check whether your downloaded recovery image is not broken. In case of
   1. windows type Get-FileHash <image_filename.img> on your computer.
   2. linux type sha256sum <image_filename.img> or alternatively shasum -a 256 <image_filename.img> on your computer.
6. The result should look like

   b6494278d0a399547a9344a6018a30b388f71a97ef52989bcdd661002f3a8631  lineage-18.1-20210906-recovery-FP3.img
   

7. Now compare the number to the one given on the recovery image download page. Ensure, you are browsing secure with "https".
   
8. Be aware, in the next step all data will be erased on your fairphone!

5. Install LinegaeOS recovery image

All checks passed? Then lets continues:

1. Type on your computer fastboot oem unlock.
2. If your fairphone reboots, you might have to do the steps 2.1-2.4 again to re-enable USB debugging. Then adb reboot bootloader will bring you back.
3. Install fastboot image & reboot to recovery
   1. in case of Fairphone2
      1. by typing on your computer fastboot flash recovery <image_filename.img> (<image_filename.img> is the img-file you have downloaded in 1.).
   2. in case of Fairphone3
      1. by typing on your computer fastboot flash boot <image_filename.img> (<image_filename.img> is the img-file you have downloaded in 1.).
      • If you see something like "boot partition is smaller than boot image" you might find the solution here.
      1. On the phone you should not see any difference and you phone should remain in the bootloader screen. Then hold Volume Up + Power. Release when boot logo appears.
4. Reboot to Recovery without starting your original rom
   1. in case of Fairphone2
      1. With the device powered off, hold Power + Volume Up. Release when boot logo appears.
   2. in case of Fairphone3
      1. Use your bootloader to restart
         
      2. or use the button method, hold Volume Up + Power. Release when boot logo appears.

Please take care not to boot in to your old Android / FairphoneOS. If you missed the proper reboot into recovery by buttons you've to step back to step 1. because your old os reinstall its own recovery over the one just installed.

6. Install LineageOS

This step is no more dangerous. You can retry as often you want to. The LineageOs boot-loader will verify your binaries. If you are already in the recovery mode you can go to step 6.3.

1. Choose Factory Reset - Format Data/Factory Reset
   

2. Return to main menu
