[Tutorial] Downgrade Firmware 3.50

you can try taking your faceplate off and removing the right trigger button as well as the rubber pad/metal housing below the trigger then try and run the downgrader. if you need a guide you can find one here http://www.llamma.com/PSP/repair/comple ... sembly.htm

That and he can try and clean the metal contacts that the r trigger uses. That way it would be regular anyways :p

great tutorials

How do I play lumines again?
It downgraded to 1.5 but when I load lumines and press start to play, it just goes to a red screen.

add: Now that its 1.5 I cannot play very many games. It tells me I need to upgrade. How can I play them again?

Well...you need to take the downgrader files off your memory stick. Also to play newer games i suggest upgrading to 3.03 oe-c or 3.40 oe-a. You can use the winstallers provided below.

Reformat your memory stick after custom firmware is installed then drop your iso and cso files in your iso folder

Hey, I have a TA-082 motherboard (V 3.11). Once I downgrade it to 1.50, can I upgrade it back to 3.40 OE? Thanks!

Downgrader guide for all firmwires
Great tut by the way

Ok bugmenot, this is a good tutorial that didn't really need anymore input unless someone had a question. It is quite disrespectful to post a link to another tutorial on a tutorial someone made. We already have a tut by staxx that is a "downgrader guide for all firmwares". I'm going to have to ask you to stop making these types of posts.
