Can I use this to upgrade my PSP from 3.30OE?
If not, how do I downgrade it to 1.5 again?

@Kvante:
You must have 3.52 M33-2 or later to install it since previous versions have a bug in the SCE updater that the 3.71 M33 installer uses.

Hi EXTER7!!
Thanks for aswering - not many people are kind to do that.
I upgraded my PSP to 3-40 OE-A and used the 3.02 OE-A to downgrade with the original 1.50 firmware from sony - without brick'ing my PSP - worked perfectly.
Now I have to upgrade the firmware to 3.71 (this torrent) - and hope that "Ratchet & Clank - Size matters" - will load without any problems (the 3.30 OE-A and 3.40 OE-A would not).

Great work - it work just f´great! The game Ratchet & Clank - Size Matters work without any trouble - I'M HAPPY!!!! ;o)

is there a way to get this to work if you don't have a windows computer?

@dekkker-
As long as you can copy the files to your PSP, it will work. I use linux and just plug the USB cable into my laptop. Then on the PSP menu, select Settings > USB Connection. Copy the files over and run them on your PSP. Directions are usually included.
