I have just turned my PS2 on and everything was working ok, the console would boot fmcb menu and i would either boot my hdloader or just boot game disc.
nothing has been touched or altered, all i did was load up metal gear solid 2 subsistance (OPL) after using codebreaker to enable cheats..... later the game crashed.
now when i boot i get the fmcb splash logo
black screen
then the mCBOOT configurtor menu
no matter what i do from here, it will reboot to this screen again.
I have no idea how to get it to boot back as normal where it took me to the ps2 browser screen with all my homebrew apps listed.
Does recovery mode work?

It seems it’s not working on Sony PlayStation 2 hardware videogame console. PS2 Slim SCPH-90004 hardware model.
Your model is probably not compatible, check your BIOS:

You may be able to use a disc based alternative:
