Install /e/ on a Fairphone FP2 - “FP2” (beta)

Tip: Please read through the instructions at least once before actually following them, so as to avoid any problems later.
Caution: Flash your device only if you know what you are doing and are OK taking the associated risk. All builds are provided as best effort, without any guarantee. The /e/ project and its project members deny any and all responsibility about the consequences of using /e/ software and or /e/ services.
Tip: Installing a custom recovery or unlocking the bootloader will erase all data on your device! Take a backup of your data before proceeding!!

Requirements

  • Take a backup of all important data on your phone before proceeding.
  • A guide on backing up with TWRP is available here
  • Ensure your phone is charged more than 50%
  • Check that adb and fastboot are enabled on your PC. If not you can find the setup instructions here
  • Download all the files and images mentioned in the download section below before starting the installation
  • Make sure you have a working data cable to connect your device to the PC. There are cables which are only for charging and do not transfer data.

  • Enable USB debugging on your device. You can find the instructions here

  • TWRP (not required if you already have it running on your phone)

    The version we used for our testing was 3.2.3.0

Installing a custom recovery

  1. Connect your device to your PC via USB.
  2. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type

     adb reboot bootloader
    
  3. Once the device is in fastboot mode, verify your PC finds it by typing

     fastboot devices
    
  4. Flash recovery onto your device

     fastboot flash recovery recoveryfilename.img
    

    Replace the recoveryfilename with the name of the recovery image you downloaded

  5. Now reboot into recovery to verify the installation

Installing /e/ from recovery

  1. Before proceeding ensure you have downloaded the /e/OS for your device, from the link given in the Downloads section above

  2. If you aren’t already in recovery mode, reboot into recovery mode by typing the below command in the console of an adb enabled PC

     adb reboot recovery
    
    Tip: You can also do this manually using the below key combination
    • With the device powered off, hold Volume Up + Power. Release when boot logo appears.
  3. In TWRP return to main menu, then tap Wipe

  4. Now tap Format Data and continue with the formatting process.

    Here a new screen may show where you will have to type Yes and confirm the action by clicking a button.

    Caution: Format Data will remove encryption as well as delete all files stored on the internal storage. Remember to take a backup first. Check Requirements section above.
  5. Return to the previous menu and tap Advanced Wipe.

  6. Select the Cache and System partitions to be wiped and then Swipe to Wipe

  7. Sideload the /e/ .zip package.

    Tip: Sideload requires actions in two places to be done. One on your phone in the TWRP UI and secondly on the connected PC which should have adb enabled. Also note the sideload process while running may stop abruptly around 50%. The console would show a message Total xfer: 1.00x. This would mean that the transfer has successfully completed.
    • On the device in TWRP,

      select Advanced, ADB Sideload, then swipe to begin sideload.

    • On the host machine, in the console , start the sideload of the package by typing
     adb sideload filename.zip
    
    Tip: Change the filename to the name of the file you downloaded
  8. Once installation has finished, return to the main menu, tap Reboot, and then System

Warning: Avoid installing any additional apps or services if suggested by the recovery. They may cause your device to bootloop, as well as attempt to access and or corrupt your data.
Success: Congratulations !! Your phone should now be booting into /e/OS !!
