That method of downgrading is working??

Guys, you`re kidding?

All those swap&feed methods dont work on our Samy, because all files on USB upgrade have signatures. If you change any of them (encrypt/decrypt/change from other version) you have to update signatures. Else TV doen`t see any files for upgrade on USB. No chance to sign firmwares until we don't have the key (xored and exists in exeDSP).
Another chance to have some kind of RSA dissabler which doesn't look for signatures (like on B series CI+), but here we also have problem: games require signing too. How do we run that RSA dissabler if finally we get it?

Patch game checker in memory?
