Deja Vu wasn't fully patched out on firmwares 5.X hence why it hasn't been released yet. The exploit needs to be reworked for it work for the higher firwmares as well as the lower firmwares but the point is that while the ipatched and Mariko units are immune to the Fusee Gelee exploit, they are still vulnerable to Deja Vu.
Thanks for explaining as always man. I didn´t even know about this "ipatched" units, they´re already in the wild right? I hope they get hacked deja vu in time.
