[Verizon Samsung Galaxy S 4] tulth:
i hacked up some python scripts and did some openssl stuff and managed to dump out one of the certs in sbl2.bin, if it helps...

I do note it says its SHA1 wRSA, which I understand to be a bit less secure.

Perhaps there is a way to spoof sha1Rsa as a coordinated effort?

edit: nm after reading up sha1 is still practically secure from small timers
