fw 1.5 to cfw 5.0

[Slade]

Hello all, I downgraded my buddy's psp with pandora to 1.5 and I'm now looking to upgrade it to the most recent custom firmware.

My question is, can I upgrade straight to the most recent firmware or am I going to have to run fifty different ****ing installers to get there?

Or let me put it this way, what's the highest custom firmware I can install to from 1.5?

Thanks in advances.

you have to go to 1.50 to 3.52 m33 then to 5.00 m33 then 5.00 m33-3
