I'm pretty sure you can just use a pandora+mms to get it back to custom firmware.

Try using Rains MMS maker to make the MMS

Bros, I don't have pandora's battery. does it still possible to downgrade my firmware? and where to get the rains mms maker? and what does this do?

sorry as im not familiar to this psp hacking stuffs...but I really appreciate if someone could help me out...as I believe my old fat version should be able to mod back to previous version.

You need this:
File Details-Rain-s-UltraLite-MMS-Maker-for-5.00-M33-4-v1.2-PSP-Homebrew-Applications -
This:

And this:
DealExtreme: $6.34 PSP Unbricker Pandora Battery for PSP 1000/2000 (1800mAh/3.6V)

Or you can make your own pandora with your battery with this:

Basically, you run the first program I provided. It will ask you to put in the EBOOT, that is the second link. Download the second link and then load that into the program. Make sure your PSP is plugged in with the memory stick in, select which drive the PSP is(F:/, G:/, etc.), and hit Make MMS.

Then you can use the 3rd link to buy a pandora battery, or make your own with the last link I provided.

Is there any site I can purchase Pandora Battery without through the Paypal since I don't have any account with them?

[WhiteCoke]

if you want you can jst make your own pandora mms.

[chrisvarns]

ronn77: there are probably hundreds of sites that allow you to buy pandora without using paypal. I got mine from amazon.

[black_vegeta]

You can buy one at Pandorasales.com

I just bought a MMS ad Pandora battery from them, it included easy instructions and I had my friends PSP Phat modded within minutes.

did u try holding the "L" botton b4 u insert pandora battery?

[ronn77]

no, I didn't. Means I should press the L button before I take out the original battery or press L after I take out the sony battery?

[chrisvarns]

Put in the pandora battery, then while holding L put in the mms i think.

[ronn77]

means take out the mms and insert the pandora battery then hold L while insert the mms?
