Hello
Back again for a new problem using Easy Installer - v0.21.2 : this application remains on the stage “Detection of device” since 2 hours, without evoluting
I guess that something is going wrong, but what ?
Salut Piero
Je pense que tu es français alors je vais m’exprimer dans cette langue.
J’ai utilisé le script d’installation que tu m’as indiqué. Je suis arrivé à l’étape 6 : Ask for unlock with fastboot flashing unlock; j’ai tapé cette commande dans ma console debian et celle-ci me répond qu’elle attend une information concernant l’appareil :
$ fastboot flashing unlock
< waiting for any device >
J’ai appuyé sur les boutons Volume+ puis Power. Mais il ne se passe rien ni sur le FP4 ni sur la console.
As-tu une idée sur la démarche à suivre ?

This page was written for Easy Installer, but it is the same issue for script install Easy Installer - FAQ. The FP3 solution works just the same for FP4.
The Windows drivers that work for your regular phone do not work when the phone is in Fastboot mode. You need a “Combination driver”.
Boot the phone to Fastboot mode and check if it has become a “Problem device” in Windows device manager. Windows update should now find the correct driver.
Each user that wants to use ADB needs to be in the plugdev group. If you see an error message that says you’re not in the plugdev group, add yourself to it using the following command:
sudo usermod -aG plugdev $LOGNAME
Groups only update on login, so you must log out for this change to take effect. When you log back in, you can use id to check that you’re in the plugdev group.
The system needs to have udev rules installed that cover the device. The android-sdk-platform-tools-common package contains a community-maintained default set of udev rules for Android devices. To install it, use the following command:
apt-get install android-sdk-platform-tools-common
… or what is output of
fastboot --version

Enable USB debugging on your device. You can find the instructions here
Your device requires a code to unlock the bootloader. Get the code here before proceeding with the next steps
Hello
I followed your instructions. On stage 7, the device proceeded with a factory reset, and automatically rebooted. On stage 8, I reboot again into bootloader on my PC but it blocks again :
$ adb reboot bootloader
error: no devices/emulators found
In the same time, the device invites me to begin configuring.
What must I do ?
Salut Piero
J’ai suivi les instructions de @aibd; j’ai aussi appliqué ta solution “vite torchée”.
J’en suis à l’étape 8, j’ai rebouté sur ma console linux mais ça bloque derechef :
$ adb reboot bootloader
error: no devices/emulators found
En même temps, sur mon FP4 qui a bien rebooté en configuration usine, j’ai un écran qui m’invite à commencer à le paramétrer.
Y-a-t’il quelque chose de particulier à faire ou je peux passer à l’étape 9 : Unlock critical with fastboot flashing unlock_critical ?
Il faut poursuivre en esquivant / desactivant un maximum de fonction proposées,
Ensuite, je ne conseille pas de reverrouiller le bootloader, mais chacun doit en juger en rapport avec sa situation (Android Security Patch date of /e/OS doit être plus recent que Android Security Patch date of FairphoneOS precedemment installé) car sinon, il y a risque de bricker l’appareil…
et avec ses desirs de souplesse ou pas
une fois totalement démarré, tu dois reactiver les options developpeurs et USB debugging
Pour retourner en mode fastboot et reverrouiller le bootloader
OK.
Actually, USB debugging was locked.
Stage 9 OK; the device rebooted after a factory reset.
I’m now proceeding to install /e/OS
Stage 1, 2 & 3 performed.
Stage 4 : I’m blocked again :
~/platform-tools$ chmod +x flash_FP4_factory.sh && ./flash_FP4_factory.sh

Hello aibd
I run again the script :
$ adb reboot bootloader
$ fastboot flashing unlock
…
FAILED (remote: Device already : unlocked!)
finished. total time: 0.000s
dessort@hp-820-g3:~$ fastboot flashing unlock_critical
…
FAILED (remote: Device already : unlocked!)
finished. total time: 0.000s
$ cd platform-tools
platform-tools$ chmod +x flash_FP4_factory.sh && ./flash_FP4_factory.sh

I checked and FP4 is actually connected and USB debugging enabled and bootloader enabled.
Is there anything else wrong ?
Hy
I added the path to platform-tools in my PC configuration, according e/OS doc “Installing adb and fastboot on a Linux PC”.
I checked :
the command “adb devices” runs :
~$ adb devices
List of devices attached
b0be97bc device
the command “fastboot devices” doesn’t give any answer.
Does that seem right to you ?
Then, I performed again the steps 1 to 8 of the doc.e.foundation/devices/FP4/install procedure. I ran the command above :
$ fastboot flashing unlock
FAILED (remote: ’ Device already : unlocked!')
fastboot: error: Command failed
$ fastboot flashing unlock_critical
