Problem loading firmware files...

[Slash]

I'm loading firmware files. Some files are loaded successfully but some makes the PSP crash. I'm using kernel mode and SetupCallbacks(); Am I missing something?

Loading a firmware on top of a firmware = bad.
Undoubtedly it will crash on files such as sysmem.prx...

You need to unload a lot of modules first, but you can't unload some... like sysmem.prx, loadexec.prx, etc.
The only solution is to patch sceIo so it reads from memory stick whilst accessing the flash, and then soft-reboot using reboot.bin whilst keeping all your patches intact. This is basically what Devhook does.
