Hey guys, I'm looking to up/down grade my PSP1003 (OFW v3.52). I've read quite a few guides, and looked on many a thread here before posting but I'm still a little confused by it all.

The guide I thought I could make the most of had seperates guides for Downgrading 3.50 and Below, and Firmware: 5.03 and below. Now I'm assuming that since 3.52 is higher than 3.50 that I will have to downgrade via the 5.03 method, is that correct?

The Firmware: 5.03 and below guide doesnt require a 'Pandora' battery as far as I can tell. And I will need to manually upgrade my PSP to 5.03, again is this correct?

This will get me onto CFW 5.50 GEN-D3, which is the correct one for loading games from memory card?

Thanks in advance for any help :)

Cheers
Philip
