No, I proposed 3 different ways of hacking the UDID in that comment. 1) disrupting the read of ECID in transit, 2) re-writing ECID by hacking the BPP, 3) a SHA1 hash collision. Any one of the 3 will do.<p>Even then you cannot &quot;flash anything&quot; to the phone. But you can flash a build signed by Apple which hard-codes a UDID check.
