I have a pink psp (1.5 upgraded from 3.01 - 3.03 then downgraded) i am familiar with downgrading and using devhook.

When i try to load iso's using Devhook on my psp it says it will reboot it and the screen just goes very dark blue but does not restart.

On my friends they just load simplay.

I have tried devhook 0.51 and 0.52.

What can i do or what ami doing wrong? Plz help.

P.S I Am succesfully on 1.5 and running hmebrew

Could be your settings in devhook. Check them again. Also, why dont you run 3.03 OE instead of 1.50. ISO's run straight from the xmb.

thx iam on 3.03 oe-c now but how and where do i put the iso's?

Isos' go in the ISO folder on the root of your psp drive. If the folder isnt there just make it and put the isos in it. Then they will run right from the xmb.

thanks that is workin.... do u know how i can run dax files?

You can't run DAX files without some sort of plugin or mod.
So you need to convert them to ISO or CSO using a program like PSP ISO Compressor: http://www.psp-hacks.com/file/900

pretty brave of you to get that pink lol

as i am a male lolz which i am

You can also use UMDGen v4 to create CSO/ISOs it works really good..
