I got a FAT PSP with motherboard prior to TA082. I've no responsibility if you damage your PSP with the above procedure.

Works on TA-079 and TA-082

i think you only know you can downgrade with pandora but this is without

**bhunter** · 09-26-2007, 10:41 PM

Isn't this just the same as recovery?

i doesn't work in recovery for me for some reason it just goes to XMB

**bhunter** · 09-26-2007, 10:48 PM

So you go into recovery mode and select to run the app at psp/game/recovery/eboot.pbp (Or whatever the correct directory is) and instead of running the 1.5 downgrade, it actually goes to the XMB?

No thats not it...maybe I saw it maxconsole and assumed it was already posted here.

@Bhunter. you can't recover from 3.71 because there is no 1.5 kernal (I think), so your only option is to use pandora. I think this hack stemmed from making pandora on the 3.XX kernal.

hehe,i'll explain it
this one runs under the xmb
and the recovery one will not run and goes to the XMB

so if you run this it will work
and if you run under recovery it won't work

I see, It makes sense now, I had no idea prior to just now that you could not run recovery, it makes perfect sense but I just never thought about it

Hardware issues, right?
Unless I have missed some milestone.....

**madsoul** · 09-27-2007, 09:39 AM

yes but the files are too large for my mem stick..

**NorthernFusion** · 09-27-2007, 09:48 AM

I havent looked into this, but what about 3.52 on the slim?
Hardware issues there aswell? Anybody?
if it supports it, could we use any 3.xx with this? (update.eboot)
