MMSX: The Latest MMS for CFW Installation

You can put your regular battery back in after it says "install complete, a shutdown is required, press X to shutdown".

If the last four digits of the serial number are 100x its a phat.

If the last four digits of the serial number are 200x its a slim.

Thanks man!
I assumed as much (for both questions). I just wanted to make sure before I ended up ####ing something up.

EDIT: Also, this may sound like a stupid question (and another one I'm already assuming the answer for), but is MMSX region specific? I remember reading that with some things like this you need a PSP of a specific region.

Hi, I have a fat PSP, OFW 4.01, A 1GB Memstick, An Ordinary Battery, and A P-Battery. When I do everything it says in the tutorial, and I place my P-Bat and memstick in my psp, I hold X, nothing happens. I try it again but I hold L, nothing happens. Not even the screen lights up.

What brand MS are you using?

Is it a real MS?

The screen doesnt even light up: Does the p-bat auto boot the PSP when you insert it, does the power light come on by itself?

I'm using a Sony Memory Stick PRO Duo, 1GB, Magicgate enabled.

Yeah, the power light lights up automatically.

Some peeps report this problem, not sure what the exact cause is though, its only about 1% that say this happens. Im trying to get this error ironed out.

Sometimes using a Sony ms causes this, idk why, but peeps stated that they had this prob with a Sony then tried the install with a SanDisk and it worked the first try.

If you have a Sandisk ms give it a go, it that dont work try the link below. It doesnt come with any extra plugins or apps but seems to be more reliable. Plus, if the Test Installer v1 works you could just copy the MMSX files to ms after the install and you'll be able to use the plugins and apps.

Download the Test Installer v1, extract the files, and copy all of the contents to the root of your memory stick. Backup and format your memory stick first though so you dont lose any important data. There is no need to run FakeCard or PSPGrader with the Test Installer v1. Also, with this method you should NOT hold X or any other button when inserting the P-bat...
