Upgrade 1.50 to 4.01 M33-2

[Tristan23]

Hi!

I just found - after years - my very first PSP again (it still has 1.50 on it).

How do I upgrade to 4.01? Do I have to go from 1.50 to 2.x to 3.x to 4.x ... or can I just go straight from 1.50 to 4.01?

thanks,
T.

1. Upgrade to 3.52 M33
2. then, goto 3.52 M33-3
3. now you can goto 4.01 M33 and 4.01 M33-2

@ Tristan23;

with the use of a service mode battery & magic ms you can go directly to CFW 4.01 m33-2 from 1.50

Thanks for that! Upgrade to 3.52 M33 worked fine.

But where can I find installation instructions for 3.52 M33-3 ?
