I have a fat PSP on 3.40OE and i want to upgrade to 4.01 M33-2.

Am I right that I can either use:

1. HellCat Recovery Flasher to flash directly to 4.01 M33-2
=or=
2. DC7 with Pandora battery

Sorry a bit confused.

thanks in advance.

i would sugest using recovery flasher...works great, at least it did for me.

I would suggest doing pandora.

Because if you happen to have a TA-082 motherboard your id storage keys will be invalid, and could cause problems on 4.01.

If you don't have a TA-082 though, then it doesn't matter.
