I've used this guide as well as An idiots guide to imessage. I have reset s/n and smuuid. Then I boot with -f and I try to sign in to iMessage and I get the message that says "Could not sign in to iMessage an error occurred during activation. Try again." I changed my Apple ID password and then it lets me sign in momentarily but I am shut out within 10 seconds and the same error message as mentioned before comes up. I've also done imessagedebug.txt. Please help? No idea what else to try. I know I'm close but I seem to be missing something. Thanks for any help.
