Let me guess - You saw this new CFW on YouTube or a site that makes you fill out a survey to download the file but you can never finish the survey because it's an infinite loop. Am I right?
I promise you whatever you saw is FAKE. If there was anything new it would be on this site or another reputable site on the front page. If you do manage to download anything and try to install it it will be a safe bet that it is OFFICIAL 3.72/4.00 FIRMWARE and you'll be out of luck unless you buy hardware to downgrade.
Fiery the angels fell. Deep thunder rolled around their shoulders... burning with the fires of Orc.
