Can not install on Fairphone 5

/e/OS Devices Fairphone

I think we’re good, I installed IMG-e-2.9-t-20250321478215-official-FP5 and locked the bootloader, rebooted several times without any problems now.

Thank you so much again to everyone who helped !

Hi everyone, the webinstall didn’t work, so I turned to this manual:

https://doc.e.foundation/devices/FP5/install

Now I am stuck at fastboot flashing unlock_critical. The phone seems to be in a loop of different bootloader screens. At the end, the only way out was a factory reset. So after a few days, I am back at where I started with all the Google stuff still on my phone.

I have tried both a linux and a Windows computer.

Anyone a suggestion for me?

1. Boot the device

  1. Enable and connect Wifi
  2. Enable Developer options
  3. From developer options, enable “OEM unlock” and “USB debugging”
  • Get the unlock code from this site and enter it

5. Reboot on fastboot by running the command in the PC console adb reboot bootloader

  1. Tip:* All the console commands are run on an adb enabled PC and in the adb console.

  2. Ask for unlock with fastboot flashing unlock

  3. Approve with volume + then power

  • The device proceed with a factory reset, and automatically reboots

9. Reboot again into bootloader

  1. Unlock critical with fastboot flashing unlock_critical
  2. Approve with volume + then power
  • The device proceeds with a factory reset, and automatically reboots

Hi Piero,

Thank you for your answer. I have done all the steps and I get stuck at after step 8. So, fastboot flashing unlock works well. But then I will do step 9 and nothing happens anymore. In Windows 10 I used gitbash. At step 6 I see adb console, but I can’t find it, so I started adb in gitbash and I checked with adb devices and see the FP5.

Is the adb console a Windows tool?

PS I have done the Windows update for the adb tools (optional updates).

At Factory reset USB debugging will also reset to “as new” so you must redo that step to allow USB debugging via Developer options, that you once did at the start.

Hi aibd,
How do I do that, when I am in the bootloader menu after step 8?

When I am in the bootloader menu at step 9, nothing happens. I can go to a screen with ornage characters (teelling me that the bootlaoder in unlocked) and from there I can go to the fastbootd menu on the phone. Is that the right thing to do?

27

Unsure of the wording on that phone, but it will be equivalent of “(re)boot system now”. That is you will just restart the phone to normal mode.

Is this not what happened?

Edit, I see a mismatch in numbering between different instructions! So I am reading this that you saw the Factory restart, then followed the next instruction to boot into bootloader. For clarity the bootloader has in green text START at the top.

Hi aibd,

Thank you for the clarification. The bootloader with the green start text at the top, has a menu. So when I do Volume + (or Volume -) I scroll through the menu and get different options. After that I push power to select that option. The options are: Start, Power off, Recovery mode, Restart bootloader. When I choose recovery mode, I get a new menu with a lot of new options. I tried ‘enter fastboot’ hoping to set the phone in fastboot modus, and when that didn’t work I tried ‘Apply update from ADB’ but that didn’t work also.

When the phone is in bootloader menu or another menu, on my pc I check adb devices and the phone is not connected anymore. So I can’t do the step: ```
chmod +x flash_FP5_factory.sh && ./flash_FP5_factory.sh

So first thing … were you able to re-enable USB debugging?

If you had difficulty to reboot the phone to normal mode Power off then just a standard power on should work.

abd and fastboot are different languages.

Good moves. You may need to do the same checks for the phone in Fastboot mode. Maybe this is telling you what you know, but before “work starts” I like to do: with the phone in recovery mode

adb devices

→ the phone will identify itself with its serial number and confirm mode.

with the phone in Fastboot mode

fastboot devices

→ the phone will identify itself with its serial number and confirm mode.

Should either command fail in Windows, open a Device manager and check to see if you have a :warning: Problem device if so open Windows update to fix the driver. A combination driver is required to work adb and secondly fastboot and possibly thirdly fastbootd, so be sure to to watch your Device manager window during progress.

on Windows PC console is called command prompt …or… windows power shell

Hi aibd and Piero,

It works! I have eOS running on my FP5. Thank you for your help and patience.
Now I am going to explore my new OS :wink:

lmfao oops please let me delete my fk up
Hilarious I was actually looking for it and I thought I’d read this whole thread but somehow I missed it… my brain is too burned out and can’t think properly anymore.

Thank you for your explanation btw! I was desperate because everything was pointing to me needing to install Linux somewhere

35

Oh, you could have just let it stand (deleting should be reversible for a while), I just wanted to point to the animation :wink: .

36

Oh it’s gone now, but I’ll write the tldr version:

For whoever on Windows is struggling with the Easy Installer not recognizing the Fairphone 5 once it goes into bootloader mode: you just need to download a Windows update, look at AnotherElk’s post (#11). No code or Linux or complicated shit needed
