Go here and dl the PSARDumper, and install it into your /PSP/GAME/ folder.
Go here if using a 1k/2k/3k or here if using a GO
DL the 6.20 OFW update.
copy the EBOOT.PBP of the 6.20 update to the root of your memory stick
Start PSARDumper, and press (Circle) button when it loads
when it finishes, there will be a new folder at the root of your memorystick called F0/
Navigate to F0/vsh/module/ and find the file vshmain.prx
rename this file to vshorig.prx and copy to the root of your memory stick.
This worked for Reaper when he lost his vshorig.prx, and he was able to sucessfully uninstall with it, you're milage may varry though
