Hello everyone!

I was surfing around and trying to find out which firmware is relevant for me but was somehow a little bit "overwhelmed" with the "mass" of different versions around by now.

I'm currently running on the a little outdated 5.50 gen-B (full)
and i would like to upgrade to the new version.
Generally just to be able to play the newer games.

Which Firmware would you recommend now? It does not need to be the newest one, just the most stable and ready for other updates. /which is the relevant tut?

I figured out maybe some infos needed:
Model: Psp-2004
date code: 7c
motherboard type: 02g
motherboard model: ta-085
umd firmware: 1.240ANov10, 2006

Just for me to be up2date:
OFW = orginalfirmware, cfw=custom firmware = hacked, right?
versions with prob is somehow not permanent? how is that meant to understand?

Thx for any help, pspluuver
