Well you would need to downgrade to 1.5 first before you can go to 3.03OE-c
Just do a search for 1.5 recovery installer and follow the directions carefully.

Download 1.50 recovery from here

Turn off your psp, when you turn it back on hold the r trigger...this will bring you to recovery mode. Toggle usb, then start up the 1.50 recovery program you just downloaded. Once the recovery program is finished installation, hit the toggle usb again to disconnect it then scroll down to the 3rd option that says run eboot from... Let it do what it needs to do agree when it asks you to, then restart when it asks you to.

BTW guys you can just go straight from 3.40oe-a to 3.03 oe-c....look at my sig. i dun t know how it works, you just treat it as if you were ona previous custom firmware, and it works, i know you already got the Recovery, this is for anyone who reads this in the future.

I know how it works:

1)First you have to download for example 3.03 OE-C Winstaller
2)After that, move installed files from 3.03oeflasher (That is folder name) to ms0/PSP/GAME/RECOVERY (make that RECOVERY folder if there's not)

3)Shut down psp
4)Turn psp on and hold R to go to recovery menu
5)Start 3rd option
6)Follow the instructions (You have to got 75% battery for installing)
7)After installing turn psp on, and there come error advertisement,but don't worry. Press circle to continue
8)Check your version from System Information, if all i correct, you have now that firmware you wanted.

Sorry if my language is bad,im from finnish...

yeah, except i didn't make it that complicated, i just treated it as if i was on 3.02 oe-b and i was upgrading to 3.03 oe-c, none of that recovery crap. it was a lot simpler.
