its not actually been tested on 3.56+ but i doubt that it would install anyway. not sure but i think PS3MFW builder packs pups signed with 3.55 keys.
i'll give it a test cause i'm going to install hens version with the XMB manager but i'm pretty sure that they will ask to renew the playstation store license but then again its kiosk/store firmware so who knows?
hen i tested your version of the hybrid firmware after i unlock the menu then go to the game category the console reboots and asks to press ps button or re-install firmware..
has anyone actually tested this? does it have the install package file options in the game category cause i think that i might have released the wrong version.
anyway, i'm going to make version 2 that will enable game update downloads hopefully.
