What To Do After DownGrading

3.30oe-A Open Edition Firmware Installer
If you have a 1.5, you can use this, Its 3.30 mixed with 1.5 so you can play your PSX games without the need for a PS3 and all the other features 3.30 has, It other best strength it it can launch homebrew just like a 1.5 and also launch ISO's straight from the GAME menu.


Devhook .52.0100 Installer
When you have downgraded to 1.5, you will need Devhook to play your Umd's and ISO's(but i advise on getting 3.10oe its can launch iso's and its just the best).
Here's a Link, to Devhook .52.0100 Installer

Lol - for the PSP, nothing at all.

What's the story with the topmenu_plugin for 3.30oe?

I dunno - haven't tried it.  From what I heard, my 3.0x topmenu works: http://endlessparadigm.com/forum/showthread.php?tid=875

i tried the one from the black theme pack, but the xmb never showed up it was just black.

i then found one from maxconsole, it worked,
i think its from your 3.10oe rco file. idk

nice tutorial

can you downgrade a 2.81 TA-082?
