So the message has significantly changed now [1] … previous comments deleted.

Are you 100% confident of

Many first time users have been uncertain how to achieve this.

Do you see fastboot positively indicated on your Bootloader screen?

[1] We no longer see

florent.wehrli · June 14, 2025, 9:28am

Thanks,
I don’t see Fastboot on my Bootloader screen

aibd · June 14, 2025, 9:33am

Are you able to use the Bootloader menu to explore your way around the phone so that you get a full understanding of the available modes? You could share an image if you like.

florent.wehrli · June 14, 2025, 10:05am

aibd · June 14, 2025, 10:12am

So you have Fastboot mode indicated in red in some images.

As you already unlocked the phone you must have selected Fastboot mode previously.

Did you know / remember that Enable USB Debugging and OEM Unlock is undone by Unlock as the phone resumes default settings. Does this need to be done again?

You know that the command

fastboot devices

or

./fastboot devices

is useful to confirm that you have the phone in Fastboot mode.

florent.wehrli · June 14, 2025, 10:29am

“As you already unlocked the phone you must have selected Fastboot mode previously.”
I think no.

How to do it now please?

aibd · June 14, 2025, 10:40am

What was the command to unlock your phone ?

Surly the fastboot command

fastboot flashing unlock

The phone could only accept that command in Fastboot mode, also called Bootloader.

Maybe you need to take a break and come back to it

You have images where Fastboot mode is indicated – voilà

Review

Perhaps because of the difficulty others have in being sure that they are in fastboot mode we see this in the unlock section of the install page an alternative:

Boot the device
Enable and connect Wifi
Enable Developer options
From developer options, enable OEM unlock
Get the unlock code from [this site] and enter it
Reboot on fastboot by running the command in the PC console adb reboot bootloader

florent.wehrli · June 14, 2025, 10:54am

wehrli@wehrli-hpprobook455g4:~$ fastboot devices
wehrli@wehrli-hpprobook455g4:~$ adb reboot bootloader
wehrli@wehrli-hpprobook455g4:~$ fastboot devices
4c280ffb fastboot
wehrli@wehrli-hpprobook455g4:~$ fastboot flashing unlock
FAILED (remote: ’ Device already : unlocked!')
fastboot: error: Command failed

aibd · June 14, 2025, 11:02am

So the phone is in Fastboot mode for sure.

But please don’t just run lock / unlock commands without a very good reason.

wehrli@wehrli-hpprobook455g4:~$ fastboot devices
4c280ffb fastboot

Did the job of confirming you are in Fastboot mode, the phone answered with its identity and state fastboot.

No fastboot in bootloader menu

aibd · June 14, 2025, 11:30am

OK. @florent.wehrli if you plan to lock the Bootloader again after /e/OS install please can you confirm that you fully understood this from the install page.

Caution: The FP4 comes with an anti-rollback feature. Google Android anti-roll back feature is supposedly a way to ensure you are running the latest software version, including the latest security patches.
If you try installing a version of /e/OS based on a security patch that is older than the one on your device, you will brick your device. Click on Details below for detailed information

But my phone don’t start on /e/os only on bootloader.

If you try installing a version of /e/OS based on a security patch that is older than the one on your device, you will brick your device.

.

i don’t understand why people absolutely want to relock their bootloader…

Thank Piero, but what can I do yet?
Sorry

piero · June 14, 2025, 12:13pm

if your FairphoneOS was really older than

This /e/OS 2.9 version includes the Android security patches available as of March 2025

try

fastboot reboot

otherwise, if you are lucky, try

fastboot flashing unlock

then

fastboot flashing unlock_critical

then install version 3.0.1

search for an unbrick yourself method i am not aware of…
@urs_lesse ? @AnotherElk ?
i will ask the french “FairPhone Angel” from Paris

contact Fairphone and send the phone to them…
in Hollande

après avoir tenté de redéverrouiller le bootloader,
l’appareil démarre-t-il maintenant ?

avec les bouttons ?
avec fastboot reboot ?
