Lo all even you up there who again insulted me this morning I salute you.After all this bull**** stories I'm gonna told ya how to downgrade, & as I can't finish it for personal reasons (and alot of wab; (??..) & I'd like to apologize for all this mess, the downgrader makes too much noise.
he 1st solution with wich we did the vid is simple but stuck the 3rd verification crying.gif .I send U the Eboots directly & will told you how method 2 works.
So, you need 2 MS & don't forget to prepare them with the directories that comes in the RAR file. All on "MemoryStick1" goes to MS1, All on "MemoryStick2" goes to MS2
here comes the method to brake the 2nd lock of "updater" you gotta run the 1st Eboot on ur PSP 1.51, 1.52 or 2.0 You'll see a blank screen & as the screen turn to black press 3 times "power" the PSP turns to "hibernation mode". take ur time & switch 1st MS by MS2.
When everything is ready press power to turn off "hibernation mode" the PSP load update correctly & says "update 1.50 ready to run" as if it was launch from firmware 1.00
There, it's stucked & it's the last check ther is on update. we did well after but rest of the job is secret
For method 2 it's a MD5 that is in eboot.pbp of update so if U modify any byte of updater it'll be launched but under the psp updater you'll see a nice alert saying "your update is corrupt & couldn't be launched" this MD5 is so big & "flashy" nobody talks bout' it.
it is located at last line of eboot under "psar" it's for that the updater check that no modification were made to eboot.
this MD5 isn't in UMD games updater, that's the trick.
the answer is Sony knows very well that U can't copy UMDs so they didn't add a security to check if psar has been modified.
I didn't find out how to calculate this MD5 & find what it corresponds to. but it's the answer !
last thing for the "UMD executable updaters" as 2.0, they are all the same as the one that can be launched from MS but they are signed differently with a special UMD flag so for the PSP it's impossible to launch it from MS.
Why did I decide to told U how it works ??
for U can finish the downgrader, I can't keep the job secret it's a free project & I hope you can finish it. thx for ur supports.
Amicalement Yoshihiro
best
i've tested this on my v2.0, my psp is not bricked, it goes to the v1.50 update start screen, but when you start it a message comes up says 'there is no need to update', but it is promising, a little.
