Installation e/os Fairphone 6

Bonjour,
Je viens de me procurer un Fairphone 6 dans l’intention d’y installer e/OS.
J’utilise l’outils / l’installateur en ligne depuis un ordinateur sous linux.J’ai effectué toutes les étapes initiales sur le téléphone.
J’arrive à l’étape 9, connecte le navigateur au téléphone et télécharge les e/os.
Jusque là tout va bien.

Le téléphone redémarre en mode Bootloader, je me connecte à ce dernier et l’installation commence.
Mais à chaque fois à cette étape, plus ou moins loin dans l’installation ca plante.Je ne comprends pas pourquoi.Je vous partage les rapports debug console de Chrome.(pas depuis le début … mais les “dernières” lignes)Il semble que le système bloque à un moment sur un fichier et n’arrive plus à poursuivre l’installation …

Après un certain temps j’ai ce message d’erreur : “Error on step: connect-bootloader
Cannot execute command flashing unlock
Cannot execute command flash keymaster_b keymaster.img
error flashing file keymaster.img Bootloader timeout: flashing keymaster_b failed after 3 attempts. Try using a different USB port or cable”
Alors que que device est toujours connecté et reconnu par linux (via des commandes comme : fastboot devices)
