OK, just a last thought, idea, and maybe good, not sure. But it cannot damage anything…

  • Install the version 220405 but do NOT relock the bootloader.
  • After you have flashed the image via sideload, reboot into the system (after step 15) )
  • Do initial setup
  • Do the update to the newest version via the updater. (Maybe you first have to install new updater: UpdaterBetaIode2Vx.apk )
  • In that case you can be sure that both slots are flashed with the iodé system.
  • enable developer settings
  • check then again in developer settings if “allow OEM unlocking” is enabled.
  • Only then boot into bootloader mode and check point 17) if the get_unlock_ability is 1
  • Only then relock your bootloader! Step 17) + 18)

You should have then a working inodé system 2.4

If you want you can then upgrade to iodé 3.0
By means, you have only to sideload the 3.0 image in recovery mode (dirty, without a reset of data). Reboot, That’s all.
To get Updates in iodé 3.0 you have to install the beta 3.0 updater from here: UpdaterBetaIode3V1

actual guide:

  1. remove SIM card and check that akku has at least 50%
  2. eneable USB Debugging and “Allow unlock OEM” in Developer Options
  3. check if adb is working and device is recognized correctly =>adb devices => ACK USB debugging on phone-screen. check box: always trust
  4. adb reboot bootloader
  5. check if fastboot is working and device is recognized correctly =>fastboot devices
  6. fastboot flashing unlock => Acknowledge unlocking on phone (VOLUME UP + POWER) Device is doing a factory reset and reboots to system
  7. start again in bootloader => switch phone off. pull out USB cable. press Volume (-) and put in USB cable in. Keep Volume (-) pressed. Phone should start in bootloader. (¹)
  8. check if fastboot is working and device is recognized correctly =>fastboot devices
  9. fastboot flash recovery_a iode-2.4-20220405-FP4-recovery.img
  10. fastboot flash recovery_b iode-2.4-20220405-FP4-recovery.img
  11. fastboot erase avb_custom_key
  12. fastboot flash avb_custom_key avb_custom_key-FP4.bin
  13. press VOLUME UP until see message reboot in recovery. Then POWER
  14. From recovery => Factory reset => Format Data/factory reset
  15. From recovery => Apply update => Apply from ADB =>adb sideload iode-2.4-20220405-FP4.zip
  16. back to bootloader mode. From recovery => Advanced => reboot to bootloader
  17. check if bootloader unlock ability is possible =>fastboot flashing get_unlock_ability → (bootloader) get_unlock_ability: 1 ==> if you get 1 then follow with step 18) otherwise do not lock bootloader (can brick your phone) and follow with step 19)
  18. fastboot flashing lock
  19. reboot system. First should see a Lineage screen doing a wipe. After a second (automatic) boot you should see the yellow boot screen and then the iode bootscreen.
  20. start setup wizard

(¹) From FP Support Page:
Alternatively, you can disconnect the USB cable, turn off your Fairphone, then connect the cable and hold the volume down button. After a few seconds, you’ll see the fastboot mode
