The video demos the kernel exploit; though it isn’t that clear. You can see Total_Noob executes something from an HBL menu and the screen flashes purple near the end. That purple flash indicates the exploit was successful. No mention of whether or not firmwares > 6.20 are exploitable by the same means.
This all seems very promising, and with a kernel exploit, the possibilities are nearly endless. Perhaps soon we’ll see fully hacked PSP-3000s and PSPgos! Total_Noob is aiming to release 6.20 TN before Christmas. So whatever you do — do not update past 6.20 — if you haven’t already.
Keep it up TN
