I realize that after you use the pandora battery to install custom firmware on the PSP, it goes to 2.71 M33.

I want to upgrade this to 3.90 m33, but I'm not sure how.

I looked at the readme file for the 3.90 custom firmware, and it says that a prerequisite is 3.52 M33-3 or higher.

So what I'm wondering is: What is the custom firmware upgrade route?

Would this work? Or is there a step between 2.71 and 3.52?
2.71 M33 -> 3.52 M33 -> 3.90 M33
