Eh oui voilà le downgrade pour les PS3 Fat 3.55 est opérationnel. On vous avait déjà annoncé que kakaroto y été arrivé, mais aujourd'hui l'outil devient public. solidpsycho de psx-scene a releasé un FW 3.41 modifié afin de permettre ce downgrade.
Voici la videéo qui montre le jailbreak.
YouTube - PSGroove.com - Successfully Downgrading a 3.55 PS3 to 3.41 Firmware
Le site PSGroove a personnellement testé cette méthode et confirme qu'elle est fonctionnelle. Une fois downgradé vous vous retrouverez avec une version du firmware spoofée en 3.56. Pour avoir un 3.41 "clean" vous allez devoir re-downgrader avec l'ancienne méthode puis re-updaté en 3.41 officiel
Par contre attention, cette méthode n'est pas compatible avec les PS3 Slim, en effet ça les bricke. Enfin si vous voulez vous servir de votre PS3 comme presse papier c'est votre problème.

Here is a patched 3.41 that allows you to downgrade. I patched the info0 to 356, and I also used Warrens method to bypass the br drive during the update. I have tested this on both of my PS3's and havent run into any problems.
