Yes, you can prepare the PS1-Exploit for your SCPH-1x000-PS2.
To prepare the PS1-Exploit, you only need a way to transfer files to MC (which you have [your friend's PS2]).
However, there seem to be some problems involved, when it comes to PS1-Exploiting V0-PS2s (those PS2s beginning with 'SCPH-1').
Maybe SP193, or another user could help here.
