Need help downgrading

[SnesR0X]

I need some help with my PSP, the goal is to get the most updated custom firmware, when I hacked the PSP I just got the downgrader I used came with the 3.03 oe-c and I installed it without thinking. Now would the best thing for me to do is to downgrade to 1.5, or is there an easier way to get M33. Thanks in advance, I used to know PSP hacking front to back but regretfully mine was stolen over have a year ago...

Edit:
Well I figured it out myself so this thread is pointless now. Owell : /
went from 2.0>1.5>3.03 oe-c>.3.40 eo> 3.52 m33>3.52.33-3>3.90 m33>5.0 m33... ughhhh xD

Well at least you managed to get there in the end. Plus, welcome back, it's been a long time sine you dropped by here.
