Could someone send me these files from 3.10 OE (systemctrl.prx & vshctrl.prx) or will they brick if I use one from another person?

Cause I installed the USB MOD but, I want to take it out. But if I only take the plugin, the games dissapear ! So I thought I had to replace these 2 files.

The problem is that I made 2 flash0 Backups and the second one overwrite the first that didn't have the modded files.

So please, if you can (and if it doesn't brick my PSP by using another persons files), send the files to me.

NOTE: they're from Flash0\kn\
