J'ai une Nexus 7 (2013), 32GB, WiFi-seulement, qui ne démarre pas. Je l'utilisais quotidiennement, jusqu'à ce que je me réveille un matin avec une boucle de démarrage. Il a été branché toute la nuit, mais était à environ la moitié de la batterie quand je me suis réveillé (après l'avoir éteint). Après ce qui semble être une animation de démarrage plus longue que la normale, il passe à la fenêtre "optimisation des applications". Elle la termine et passe à la fenêtre "Démarrage des applications", puis redémarre.
Il fonctionne en 6.0.1, non modifié avec un bootloader verrouillé. Le débogage USB est activé
Je suis capable de démarrer en mode récupération et j'ai essayé de vider le cache.
Y a-t-il un moyen de récupérer sans effacer mes données ?
