Hi, i've been on this site for a while and signed up quite a while ago, but I never got to actually post.

So how about this. My first posts are to do with a psp downgrader for all firmwares other than for TA-082-086's. But first I need a favour. It has nothing to do with someones flash so it won't brick.

You see, as a psp developper i have bricked almost 6 or 7 psp's making this, so I need you people to work with me.

Here is my possible downgrader:
link removed and is being reviewed by staff!

I just need to check with someone that has a 2.50 - 3.03 (NOT SE, HEN OR OE) firmware to launch it and send me back an analysis. DO NOT GO ANY FURTHER THAN LAUNCHING IT Can you please send it to [email protected].

Thankyou.

PS. the eboot does say version 3.04, its just tricking the psp to say that.

STAFF NOTICE: USE AT YOUR OWN RISK. THIS HAS YET TO BEEN PROVEN TO WORK.

no, i havent just edited the param.sfo (that doesn't work) its a project from scratch (other than the data.psar of the 1.50 boot.) I have had 1 tester , he said it works fine, I just need 2 more good ones so I could release the main file.

Note: this DOES trick the psp in thinking that the file has been signed.

hmm...... All you did was change the Param.SFO to say 3.04. This will not work because the psp system itself checks the firmware and inside the firmware it has code that tells wheather or not its a update to a newer more higher version of the firmware.

This is a FAKE most definitly!
