Earlier this year we reported on the PS4 DevKit / TestKit Root Kernel Dump and today MrNiato (Guillaume Leleu aka H7K3R MrNiato) of the H7k3r Team (Official Site) shared a video demo of his PlayStation 4 Testkit DUH-T1000AA DEX 3.50 Firmware for those interested! 
Here's what MrNiato had to say, roughly translated to quote:
PlayStation 4 TESTKIT DUH-T1000aa (DEX Official) in version 3.50. Console so wanted the normal price is a little less than a minimum wage.
Shown in the video:
While this isn't the first time we've covered both the PS4 Development Kit (DUH-D1000AA) and PS4 Testing Kit (DUH-T1000AA) and the Activated Testing Kit, it wasn't on a version 3.50 Firmware unit which is always nice to see in the hands of developers outside of Sony.
Thanks @YamooDookie123 for the news tip in the Shoutbox!
