How to get from 2.6 firmware to newest Custom firmware?

Hi everyone. I'm sort of new to this whole Custom Firmware thing. I currently have version 2.6 firmware and have been running eLoader for the longest time, but would like to have the newest custom firmware instead. I think it's M33-4? I could be wrong. I would also like to know what the chances are of bricking my PSP while doing this (probably a noob question that's been asked 1000 times, so sorry in advance lol) Any help would be greatly appeciated.

ya, you need to use a Downgrader to get to 1.5 so you can upgrade to CFW, or use a Pandora Battery/Despertar Cementerio to install CFW on your psp

i had a 2.6 once do u have a GTA LCS the unpach 1?

It's alright. I got to 3.71 M33-4, by finding and reading some guides. Thanks anyway though!
