Just took a look at it, it looks very similar to #33. It uses an additional key we called "secureInstallId" in uofw (not sure it's its official name), which is passed to the decryption function sceMesgLed_driver_31D6D8AA
, but I'm not really sure where that key comes from.
It looks like it can come :
- from the sceKernelLoadModule*() call itself
- from init.prx which gets the npdrm key from loadcore, coming from reboot, ultimately coming from loadexec's
sceKernelLoadExecNpDrm
If anyone has any info about what's the game update run process, I can take a deeper look at it, but for now I'm quite clueless.
