[GUIDE] Upgrading to 3.71 M33

[Bobtentpeg]

Please, I have a FAT PSP with the "3.51 M33" firmware installed and I would like to upgrade to the "3.71 M33"

Could you point me to a guide to upgrade my PSP from "3.51 M33" to "3.52 M33-3 or 4" since this is a pre-requisite for the "3.71 M33" upgrade.

Thanks a lot for all your time and attention.

...because its soo hard for you to look right.

I saw the guide you pointed me, but I though at first, that it could only be used on a 1.5 firmware, and not on a 3.51 M33 one. (I'm new at this stuff)

I've followed the instructions and it worked like a charm! Now my PSP is 3.52 M33-4.

Now... One more question...

Could you give me a personal opinion if I should or not upgrade to the 3.71 M33 firmware?

I'm only concerned about stability and compatibility. I don't care about themes and customizations.

Again, thanks a lot for you time!

371M33-3 is perfectly stable, the PSX emu is about that some as 3.52 M33. noUMD is basically the same.

Ok, so I'm a little confused when it comes to this. Here's my current setup: I have one of the original PSPs (1.50 fw) that has been upgraded to the 3.10 OE-A fw. I want to upgrade to the most recent custom fw but I'm not quite sure which method to follow. I read the tutorials above and i'm still a little sketchy.

There's two obvious choices, the 3.51 or 3.71 both the M33 fws. Here's the thing, I also have custom emulators that I run under the 1.50 to play old NES, SNES, Genesis, etc games.

Help? What should I do and which custom fw should I use given the current settings?

Thanks.
