[MID1024] Pas de wifi

[jnjn63]

bonjour,

J'ai récupéré une tablette Polaroid MID1024PCE03.133. Tout fonctionne bien sauf le wifi qui refuse de s'activer. Je n'ai pas l'historique de cette tablette donc j'ai tenté un factory reset. Au démarrage, le wifi accepte de passer sur ON pendant 3 sec mais aucun réseau n'apparait puis il se remet sur OFF sans pouvoir être à nouveau déplacé sur ON.

Avez-vous une piste? Je ne trouve pas de ROM officielle, ni de custom? Avez-vous des infos?

Voici le résultat d'un dmesg:
