"Some Info about the Update/Downgrade process For my Friend Zeus m8 :
Hi all i give my answer to Mr-A XD . and that it's my old work from august but i think that can help you Mr-A for your downgrader Muhahahha.
Ok, so u wanna know what i know and where i am in this fucking project?
im gonna try to explain u a little bit but i can't give u all the informations
as some lamerz try to get WAB Brains as they dont have one...
I publish those informations as with them u can't do anything exvcept trying
to work on a Downgrader with more clues then now...
Well, for those who want to know if the WAB Downgrader works, just look at
our vidz on wab.com...
WE ARE NOT A FAKE TEAM WITH FAKEZ BRAINZ AND FAKEZ FILEZ !
Just look at what we have ALREADY done ... which team could say :
I've done more than WAB? ...
Everything is in this File :
X:/PSP/GAME/UPDATE/EBOOT.PBP
1st :
The EBOOT.PBP in the folder X:/PSP/GAME/UPDATE/ is detect by
the File : game_plugin.prx and is verifyed in the param.sfo
of the UPDATE_VER if it's superior of the one contain into
the PSP. If so, the File is launch.
2nd :
The EBOOT.PBP is launch, and the PSP extract the ELF encrypted
of the EBOOT and verify if it's validate by the loadexec.prx.
3rd :
Then, during the Black Screen, the PSP load another PRX :
update_plugin.prx which is the PSP OS Updater. So the ELF
of the EBOOT.PBP is a PRX and NOT an Exe file as many people
believe...
4th :
When it is launch, the PSP accept to uncompress the PSAR and
test the validation of each file he extract into the RAM 1 by 1.
If there is no error, then it check again the entire EBOOT.PBP
and extract one more time the ELF and look if it has been
modified. If everything is ok, then he accept the Update .
SO AS U COULD SEE, IT'S NOT THAT EASY TO MAKE A DOWNGRADER
AND SONY REALLY ROX BUT AS U KNOW, ALL COMPUTERS DATAS COULD
BE HACK AND ...
Just keep the faith into our cool Team. We've always done what
we said so just believe us, not the rumors or others lamerz... for all other i cant give anything more About all check sorry . way our downgrader and forget all fakes

On aura peut etre ce qu'on attend MERCREDI !!!
hey guys i decided to make my own downgrade. I know its alreayd been done im just here to show wat ive done. and ive told people ive gotten as far as risingsun but they wanted proof so here it is. Enjoy

it goes to a screen and it has the update text in the background but then a corrupted data error appears because the encryption has been broken. I am now working on trying to keep the encryption intact. Good luck to neone else working on their downgrade.
btw this is only intended to work for 1.52-1.50.
