esto puede ser la bomba

a ver señores sin empezar a criticar como de costumbre todas las mañanas me paseo por distintos foros de habla inglesa,aunque no es mi fuerte y he visto esto a ver si alguien lo pudiera traducir
creo que es super importante de verdad os pongo toda la conversacion que hubo en este hilo perdonad por el spam pero insisto es importante:

Decrypted updater binaries

--------------------------------------------------------------------------------

Hi, fairly new to the forums... and PSPs in general.

Couple of questions:

1) Assuming the updater application binary is encrypted/digitally signed, is there any way to obtain a decrypted version for analysis from a 1.5 PSP?

2) Is there any documentation on the PSAR (PSP Archive?) format?. I guess it contains the firmware image to be flashed and is encrypted also.

3) Has anyone looked at the possibilty that the updater goofs when parsing/extracting the PSAR? Or is it just a straight load file and checksum it?

4) Finally, has anyone looked at a malformed (FAT) filesystem on the MS? How does the PSP handle it?

Any sensible answers would be appreciated

if your loooking for that updater thing people are talking about then here are the two links you need:

http://psp3d.com/attachment.php?atta...7&d=1137535675 - this one is the param.sfo files for fw 1.50, 1.51, 1.52, 2.00, 2.01, 2.50, 2.50, 3.00.

http://psp3d.com/attachment.php?atta...6&d=1137533611 - this one is the actual eboot. you need to change the param to your psp fw version of course.

if thats not what you were looking for, talk to fanjita.

I'm looking for a decrypted dump of the updater application (I'm guessing its the data.psp inside the updater EBOOT) any version--if possible v2.6 as that's all my PSP will execute

Sorry if this type of request is not allowed on these forums. Hopefully someone can put me straight.

Cheers guys.


hasta ahi vuelvo a repetir creo que es importantisimo.gracias
