Luca Todesco shares to the community that this exploit is functional for firmware 4.06 and 4.07, up to its maximum firmware, 4.55. Anything over that will be needing a different exploit. This is not an Entry Point/WebKit Exploit, so please keep that in mind! Once WebKit is confirmed and functioning on that specific firmware. It will be time to start playing with a higher firmware. The higher we go, the better opportunities the community will be receiving. If you're on 4.05 firmware and below, don't update since this is not fully implemented for the community. The information added on to this topic after this will be input directly here, so keep that in mind!
