Team Typhoon, the guys who did the ChickHEN (your remember Davee, right ?), just posted a video showing a PSPGo running homebrews as well as a recovery menu and some features that can only be accessed through Kernel Mode.

It seems they found a user Exploit AND a kernel exploit on the 6.10 Firmware.

Bad news is, they don’t plan to release the exploit, for some reasons unknown yet (probably related to some other groups using their work for ISO Loading despite their strong requests not to do it).
