PROUpdate - BASLQC/procfw GitHub Wiki

The PROUPDATE Executable is part of the PRO CFW Project.

Its purpose lies in installing the Aftermarket Modules to the flash0 NAND partition for later execution through a QuickStart.

The PROUPDATE Executable aquires VSH stage NAND writing permission via a PXE environment which temporarly sets the Installer Executable as the main XMB shell.

This PXE environment in turn relies on a Kernel Exploit to setup a minimalistic CFW environment.

I'm on 6.0 it says I can't update. Can I down grade?

Downgrading might be a problem, but (as has probably now become evident) upgrading to 6.2 (or 6.6, if you've got a g1 or g2 PSP) will definitely allow PRO-B10's updater to work. Other 6.x versions should work too, but those two will allow a permanent install, which is marginally less irritating.
