🇫🇷 FP6 échec installation sur e/OS installer

[Parpaing]

Bonjour all,

FP6 échec installation sur la page /e/OS Installer

Je suis sur Mint 22.2, j’ai essayé l’installation avec Brave et Opéra puis sur mon PC portable aussi toujours avec Mint 22.2, toujours échec au step 22/24 avec le message d’erreur suivant sur la page e/OS installer:

Error on step: connect-bootloader

Cannot execute command flashing unlock
Cannot execute command flash devcfg_a devcfg.img
error flashing file devcfg.img Bootloader error: Bootloader replied with FAIL: Flashing is not allowed for Critical Partitions

Toute la procédure a parfaitement été faite avant, je précise qu’à ce moment là, ma SIM a été retirée du FP6, mon FP6 a sur l’écran en vert en haut “start” tout en bas, c’est bien marqué unlocked mais rien ne se passe, je suis sur android 15, mise à jour juillet 2025. Je redémarre alors le FP6 qui revient heureusement sur android 15. Je ne voudrais pas transformer mon FP6 en parpaing alors d’où vient ce problème? La procédure était tellement facile à faire avant ce message d’erreur. Faut-il laisser la SIM pendant toute cette procédure? Je ne veux surtout pas l’abîmer car j’habite dans en endroit très isolé et je suis uniquement en connection modem 4G 5G. Merci de votre aide.

@Parpaing

Flashing is not allowed for Critical Partitions

Exécutez la commande “fastboot flashing unlock_critical” dans une console.

Too late, android 15 then refused its last update and I therefore reinstalled with an android that was too old for the update (May 2025), I had time to see the Murena logo and it then bricked, bootloader locked and impossible to make it work. I should never have allowed the closing of the bootloader in your procedure. I now have a brick! If someone builds a house, I can participate in their building!
The Fairphone service is very long, too long, I am waiting for an RMA ticket for repair, Fairphone SAV, it’s a real business to break bricks!
My criticism is therefore without appeal in the face of the facts: fairphone, it’s free but only for the hardware, not for the software! Google goes to hell! I have nothing to kick your ass!
If Fairphone was really free, then there would be free software to flash my Fairphone 6 and repair it myself! Or in hardware, a micro ROM under the hood that can be removed and replaced with a new one sent by the customer service? I flash well the bios of my PCs. Give me a free software under linux to flash my Fairphone 6 which is far, very far from being free!

A clear guide to install /e/OS on your Fairphone

in 3 copy / paste actions ! because even well illustrated, the “web-installer” often don’t work, and because the official documentation is imbuvable for a new user. here we take the Fairphone 6 as example, but it is the same process for all Fairphone devices. Windows Guide : Expand Linux Guide : Expand macOS guide : → comming soon ! (just need a MAC user to share me a few specific informations) Feel free to ask if you still encountred issue. see also : A clear guide to Upgrade your /e/O…

If you plan to relock the bootloader after the installlation

(not mandatoty, only available with Official version, why relocking ?)
Most important thing to take care about is the FairphoneOS “android Security Patch Level” already installed on your device before you start the install process.

It must be OLDER than the “android Security Patch Level” included in the /e/ build you want to install, otherwise you risk to change your device into Brick.
