Updating from 3.40 OE-A to 3.55M33 and then 3.90M33

[Contracts]

I have no idea were to start. I searched these forums and i've only came across that you have to update to 3.55 first and then 3.90. I have a PSP with 3.40 OE-A, an original PSP (the fat one) and I have a TA-082 Motherboard. So, can someone point me in the direction of what I need to do, a link to a Tutorial perhaps (I searched but couldn't find), Thanks in advance.

I have stumbled across tutorials. I found one, followed what it said but once I executed it said it was finished but i'm still in 3.40 OE-A...

All of the custom firmware updates comes with a readme file, just read them

and BTW it goes like this: 3.40 OE-A --> 3.52M33 --> 3.52M33-4 --> 3.90M33

Alright, thank you I'm at 3.90 M33-2 Now. Curiously though, how do I get this Go Messenger, and PSN Network stuff, and is it possible to get Skype on PSP Phat now?

[mike_jmg]

I don't know about Go Messenger, I think it's only for Europe (so I have no Idea)
PSN Network can only be accesed by PS3 or PC
Phat can't get Skype because of the lack of extra ram

Oh ok, I only mentioned that because I had read somewere someone mentioning that they have it on PSP Phat but it runs with errors or something on the After Dawn forums I think. (skype i'm talking about)
