Magic Memory stick for PSP 5.00m33

For all you PSP hackers and wanna-be 1337s, I've prepared a magic memory stick for you :] This contains- The Pandora battery downgrader 1.50 PSP firmware 5.00m33 firmware Requirements- PSP Tool or Pandora battery PSP wall charger (trust me, you WILL need this) A 64Mb or higher memory stick (32Mb is too small) Instructions- Plugin your memory stick into your computer. Format in Windows, so it's completely blank Unzip everything onto the memory stick Insert Pandora/Tool battery into the PSP Put the memory stick into the PSP Follow instructions on screen to downgrade to 1.50 Grab a coffee or a girlfriend :] After it's done downgrading, run the 5.00m33 installer by going to game -> memory stick Grab another coffee Reboot Enjoy *NOTE- This has only been tested on the fat PSPs. Although it should work on the slim PSPs, keep that Tool/Pandora battery handy just in case you need to unbrick it :] I'm so sorry about the slow download speed! My internet connection is pretty slow, so just bear with me! Also- SEED! SEED DAMMIT!

I do not believe this will work on the Slims. They cannot be downgraded to 1.50 If they are already custom, the upgrade will work, but do not downgrade to 1.50 without knowing you will likely brick your PSP, possibly beyond repair by you. Just a word of caution.

well ive got a fat psp and ive downloaded this and it is rubbish had to take me psp to shop to get fixed and it cost me nearly £100

Moose99 BUT dinocrisis111:
You have to UNZIP and NOT unrar! Now maibe you have found out why you crash your PSP...
big diference between files zipped and unzipped!
Moose99 you were more cautious, but if you look for the size of all folders and files you will see big diference! ~25 against 40MB (zipped).
I have used WinZIP 11 pro.

fry2fish you make no fucking sense
pokerface-ejb this thing right here is the first step, i believe that no matter what firmware you have as long as you have a compatible PSP, Pandora will do the trick
dinocrisis111 probably because it was a hardware issue
Thanks bigplrbear for uploading this, saving me the headache of having to do it manually again.

You can not install 1.50 on slim. The best way to get custom firmware is with a pandora battery and psp pandora deluxe(software)

If you need a pandora battery you can get them for under 10$ from and that even includs shipping

This is not only good for noobs but also good for those of using Windows Vista or Windows 7. I could not create the memory stick in Windows 7... because you can't! (I've done it before on an XP machine)
Thanks bigplrbear!
