How to Fix iMessage

[TomHsiung]

The problem is that I have a valid SN but Chinese AppleCare cannot find this SN in their records. So they say it's the issue of my computer.

I am going to make a phone call to US AppleCare tonight. I wish I would succeed. I think the SN, ROM, MLB, and smUUID must be generated simultaneously.

Used a SN that was from a Real Mac Pro But not His

I don't know if I am allowed to say this but one way to get past the valid SN check is to give them a valid Mac SN, search the internet for one, many people has used this method or you should have said, you are away from your machine and you may have copied the SN wrong. They won't register you as the owner of the valid SN machine its just part of their verification checks. Good luck.

Many people are speculating on the number of digits or formats:

This is coming from a Dell E6320 under Yosemite 10.10.2 with Clover. iMessage is working.
I replaced some numerical digits with ? to avoid that someone make a duplicate.

Yea I note some people had success with a 17 character MLB and others struggled and switched to a 13 and had success so who's to say if your apple ID coupled with your machine's specs has got to pass Apple's security plus any other checks they may or may not do. I can only echo Jay's advice to follow his guide faithfully to fix the problem.

I needed to come on and say that 2.0 tutorial worked 100%

(I went through every step and followed each one until issue was found) - PERFECT tutorial!!!

1. My original info was Black listed because there was an error in my MLB SN
2. Created new set of all numbers using system
3. I have 2 step up and running so after compiling and verifying using message deub, i logged in and was asked to crate a password strictly for my iMessage and FaceTime on new machine

4. system is now fully functional again.

5. Thread creator deserves a medal for his!!!!!

I had the same problem with the "Failed" on BoardSerialNumber field and solve it following the steps of "Reset FileNVRAM Plist" of this guide, then use a MLB Generator again, restart and run iMessage dubug to verify that the valors reamain, log into iMessage, obtain a customer code and call apple..etc, etc..

Well I tried resetting FileNVRAM, but for whatever reason I'm not finding any nvram.uuid.plist's. Anywhere. Is it a hidden file?

The question still is what does your partition map look like and is Windows 8.1 installed in UEFI mode. You can boot Clover from a Hybrid MBR if you are not running a pure GPT. It might as simple as installing clover in the EFI partition of your drive but you still haven't posted the "diskutil list" output.

Here's the output, as requested. Windows 8.1 is installed in legacy mode, or I wouldn't have it working at all, as chameleon/chimera doesn't like UEFI windows.

I get this error "An error occurred during activation. Please try again later."

I had SID bug and successfully fix it. But MLB remain the same on Rom changes if I change system definition. Please help me on this. I thing my Serial number is blacklisted by apple. How can I change me Boardserial Number or MLB?

 

[Riztnack]

I have gone through this guide 5 or 6 times now, even reinstalled to clover and nothing. An error occurred during activation. I just cant figure it out.
