80020148 error

i got this 80020148 and i couln't fix it.
well i got a PSP 3000 running on 5.03 Gen-A (Full). when i try to get the menu by pressing SELECT it would't turn up. so i went through forum and found out that ultimate VSH menu will restore the prob. but it didn't either. it installed but when i press the L+R+[] the menu didn't came. So any 1 can held me out in this matter..!! PLZzzz

Reboot the PSP holding the Start Select [] and /\ to restore the defaults now run ChickHEN/MHUSpeed and the CFW - you should now have VSH access!

u mean press "Start"+"Select"+"Square"+"L & R" together and turn on. if so i did it try pressing select after rebooting on ChickHEN but didn't work. also i use another thing i use after i reboot on chickHEN. i install "INSTALLER LOADER" app. after that i use "quick updater 5.03 GEN-B".

So is it correct what i do or is there another way to over come this matter..?

Install 5.03 GEN-C and see if the menu appears.

press start select square and triangle while booting - it restores flash 1 to defaults and resets all the settings to default! after you reinstall chickHEN and your PCFW you can access the VSH or UVSH with select again!
