3.02 OE-B to 3.03 OE-C upgrade

Sorry if this is in the wrong place

Basically I just downloaded 3.03 OE-C Upgrade and seen as im new to this I haven't a clue what to do.

basically it says

- Copy oeupdmaker and oeupdmaker% to /PSP/GAME if you are in 1.50, or to /PSP/GAME150 if you are in
2.71 SE, 3.02 OE or 3.03 OE. - Done

Copy also the 1.50 and 3.03 updaters with the names 150.PBP and 303.PBP.

This second part were it tells me to copy these two files has me stumped, where are these two files and what will their current file names be?.

You have to download the official Sony Firmware 1.50 and 3.03 Updates. Do a quick search on Google or other websites (not sure where they are around this site - I'm new to this one myself).
Their original names each will be EBOOT.pbp (both will be the same). Be careful not to screw up which is which, and rename the EBOOT.pbp from the 1.50 updater to 150.pbp and the one from the 3.03 updater to 303.pbp.

Right then, first what you do is get the 1.50 updater and then rename it from EBOOT.PBP to 150.PBP. Likewise afterwards get the 3.03 updater and rename that from EBOOT.PBP to 303.PBP.

You can obtain both of them from below.

1.50 updater
3.03 updater

Cheers folks, working now.
