As of yet, there is no downgrader for firmware versions 3.72 without using pandoras battery. I'm pretty sure there is an article on the site with everything you need to know about pandoras battery, i fnot google it. It explains how to make one then turn it back. hope that helped Deekid

Yes, I see you wanted to know how to make pandora battery. Here is what I advice to people who have 3.80 Sony Firmware. There are 2 methods. One is cheaper for noobs(not to offend you) like you. 1)For noobs(or beginners who dont wanna messup their psp and do it safer way. (works for all bricked psp, to Sony Firmware 3.9. ->Go to google.ca, ->Type in "Unbrick PSP, your city name, your province/state. (for example, I live in Windsor, In Ontario, Canada. What I typed was "Unbrick PSP, Windsor, Ontario". -> If you have done it correctly, There will be website that starts with yourcity.kijiji.ca, go to the site. And You will see bunch of people who will downgrade your psp for cheap with their address provided. -> Good thing is these people are really professionals. They will install customfirmware in your psp for Price range between $10-$30. I think that is cheap. ->Bad thing is you dont get to keep pandora battery and magic memory stick (this is required if you wanna switch back and forth from Sony Original Firmware to Customfirmware). But WHY WOULD YOU WANNA SWITCH HM?? YOu ALREADY HAVE CUSTOMFIRMWARE AND YOU CAN ALREADY PLAY ISO/CSO games. So yeah.. Thats what i would suggest 2) UNless you are really rich if you think, You need to Buy Sony Battery (Old sony battery) which costs around $45, and you need memory stick that is 2GB or less. To make pandora battery, Open up your PSP battery that takes about 30 mins SOLID! http://www.youtube.com/watch?v=5D5SgCdJNCI&feature=related. go to that site. It will show you what wire to cut, etc.. But Beware!! IF you cut or Touch! Wrong wire Your battery is fried (means its meaningless and you need to buy another battery and waste $45 money and time. To make magic memory stick Now follow this guide on this link. http://forums.afterdawn.com/thread_view.cfm/591203 When 2 of my friend tried to make magic memory stick + pandora battery, One of them got custom firmware, but unluckily my other friend bricked his PSP!!. Now, He is using First method That is go to some expert and install PSP Custom Firmware. Now You SEE??? If there is grammer mistake please dont come after me.. I dont like to write a lot:) I like 2 play a lot. So thats that. IF this is not useful dont bark here please..
