It now has signature-check generation.

Yes, it works with 2.81, so don't scream OMG IT WORKS ON 2.81!

Good work Harley

**hàrléyg²** · 09-09-2006, 10:02 AM

It's not mine, its Alex's. I'm not going to say i helped either as what i did do was for Mathieulh, Alex didn't use it.

**PopeOfDope** · 09-09-2006, 10:06 AM

Can you please explain signature check generation for us? Sorry for being ignorant but I just want to know if this is a major advancement or minor.

**hàrléyg²** · 09-09-2006, 10:12 AM

It's major.

It uses the kirk engine on your PSP to generate SHA-1, then uses it as the headers.

I explained it, Well i quoted Mathieulh but my post got deleted by hardrive for some reason.

Alex has successfully generated the sha-1 key area on a 2.81 module today.
An updated 2.80 psardumper mod should be released shortly @ http://dax.lan.st/ featuring generation of the key area from your psp, which would allow to devhook 2.8x firmwares (you still need a new devhook version tough)
as well as it would allow to manually flash 2.00+ firmwares into your psp.

Cheers

UPDATE: The new psardumper mod featuring sign check generation has been released.

What exactly does that mean?

**Vee** · 09-09-2006, 10:14 AM

So what does this mean?

We can put 2.81 on devhook?

**Train** · 09-09-2006, 10:15 AM

This has been out for awhile hasn't it?... It was posted on irc://lan.st last night I believe, noone has just bothered posting it

**hàrléyg²** · 09-09-2006, 10:15 AM

When the new devhook comes out it will need this to emulate 2.80/2.81.

**DeMoN X** · 09-09-2006, 10:19 AM

I have a question, Is it true we can no longer use another PSP's decrypted firmware dump for 2.80/2.81, Because of the new SHA-1 stuff?

...
read the topic please

**hàrléyg²** · 09-09-2006, 10:25 AM

To someone who just said if this is the same one as last night, no.
This can now generate the SHA-1 headers using the kirk engine.

**HaxxBlaster** · 09-09-2006, 03:34 PM

Exactly what do the last missing devhook files do? Does it get the directorys of the files? If so, you could change it yourself.

**Grimfate126** · 09-09-2006, 03:47 PM

to all who dont understand the SHA-1 thing:

in simple terms:

sony have put a crappy system of making new keys to stop devhook from emulating 2.8/2.81. but, obviously, they have failed again. now, why am i not surprised? next thing you know theyll be like, "everytime u turn ur psp on, ull have to pay 10 cents to use it"

and.. if you dont get that, then an even simlpler version:

Dark_Alex > Sony

simple enough?

But still great work.
