GTA LCS Cheat Device for Firmware 3.02 OE-B

Can anyone direct me to a guide on this?

Umm i dono what it even is? Maybe try google or use the search feature the board has. Or ask somebody like Jesse. Sorry.

I tried google but I couldnt find anything for 3.02 OE-B.
Does anyone know which Custom Firmare Im suppose to use?

How come you don't just upgrade to either 3.03OE-C or 3.40OE-A? It should work with one of them.

Because I dont know if its safe to upgrade directly from 3.02 OE-B.
If it is could someone get me a download for a direct upgrade?

Why would it not be safe? If your that worried just downgrade to 1.5 and upgrade to whatever you want. Easy that way. Or go directly to whatever you want.

Well from my previous knowledge I remember that some firmwares had to be updated one by one at a time.
Is there anywhere where I can upgrade quickly to 3.40 OE-A?
EDIT:
Argh, okay IVe read that anything above 3.03 OE-C cannot use the cheat device.
Isnt there a way to use the PRX on 3.02 OE-B?

I still have no clue sorry. Maybe don't cheat?

No thanks. I asked on PSP-Hacks and someone said I need 3.03 OE-C for this.
DOes anyone know if theres an easy installer for me? Because I just dont want to risk anything since I want
to go directly from 3.02 OE-B to 3.03 OE-C.
