Re: Service Mode Trigger in older models...

auth keys is generated by fw controller based in a seed like a unique key given by the psp, instead of being just fixed value Yep, it's true. If we can get that firmware it is game over. We have fw (from standart battery), but game not over. Second step is understanding auth keys algo. Dump syscon ...

Interesting, PSP will play a plain NPUMDIMG image.

Something tells me this will be fixed, not like we can't encrypt those though.

Re: PS3 packages and how it leads to PSP signing

Of course. I was trying it on 01g, but i had to reflash FW many times. I guess it has to be GZipped (or another compression), but i don't know how to GZip it for PSP kernel. Yes, afaik kernel modules are gzipped, it just uses regular gzip though although some new modules got kL4E compressed if I re...

Haven't tried yet here. It'd likely just work the same way by using an existing header and crafting the last 16bytes to match the CMAC. I'd rather try this on a 01/02g first though.

Re: PS3 packages and how it leads to PSP signing

And also, why are not all homebrews build as PRX, i though it is required for new (C)FW. Because as I said older FWs used static ELFs for executables on EBOOTs (even if I'm not sure 100% and Mathieulh says this is wrong :oops: ). I'm pretty sure I remember seeing official games as static ELFs, but ...
