Turn off your PSP completely (holding on to the power button up for 10 seconds)

Hold R button and turn on, You'll be in the Recovery menu.

Choose "Configuration". (Press X to go in)

and You'll see the "Set GAME folder kernel", press X to change it into 3.52.

Last, choose BACK, and then EXIT.

Ta-Da~

You probably have a hard downed PSP. Meaning, it was downgraded by hardware not software. The Sony updater does not seem to run correctly on these PSPs so I think you will need to use the Pandora battery method to get to 3.71 M33:

You need the 1.50 update (150.PBP) placed on the memory stick root (X:/)

It's not included in the kernel pack, you need to download it separately.

Here's a link:

it looks like it went through the process without any problems the only thing is that i tried to put the theme on (reason why i was looking for the 150 kernel) but it didnt work i got internal error 80108351 im guessing it had nothing to do with the the adddon but thanks a bunch for the help

hey, i have version 3.60 but can i do these steps wifout a pandora battery?

Nope. For Slims that need to go to custom firmware from official firmwares, Pandora is the only way now.

I am a total n00b here so any help will be highly appreciated! I just bought a new PSP Slim with the 3.60 FW. I want to update it to CFW 3.71 M33. How can I do it? I do not have another PSP Phat to play around with. Please give me a full guide.
And BTW what does bricking mean? ^^

You're only way is to use Pandora Battery.
You'll need a phat PSP battery in order to make it.

Bricking means that you're psp doesn't work when you turn it on, which makes it like a brick. that's why we called it bricking.

Will this work if im already running 3.71 M33? And want to 1up to 3.71 M33-4..


There's no need to install again if you already have 3.71M33.
Here's the 3.71M33-4 Update: LINK

Please could you add to both the 3.52M33 & 3.71M33 guides that we can jump from 3.52M33-1 to version 4, and same with 3.71M33-1 to 3.71M33-4. Some people are naive and go through each update/patch (version 2, version 3, version 4).

Also, please can you also add instructions on how to install the 1.50 ADD-ON plus how to get POPs working (to play PSX games again).

Many thanks

HERE are the latest firmware install guides and update/ patches.

As 1.5 Add-on, just Copy the "UPDATE" folder to ms0:/PSP/GAME. Run it on your PSP.

I'm not sure of POPs though, never got time to check it out, as I myself have no PSX games and have no intention downloading pirated ones.
