For step 4, when you say you took 4 numbers out from the middle to make the 17char MLB 13chars.... Which 4 numbers? What position did you start at to take them out?
Lets pretend this, obviously invalid MLB, is the 17 char MLB: ABCDEFGHIJKLMNOPQ
Which 4 letters did you remove?
I took 4 numbers from the middle, not letters. In the end l don't think it really matters. When I tried using my Apple ID I got the contact Apple message. Started reading other sites and forums and there's a lot more about S/N and MLB. I think I'm not allow to put those links here, but you can easly find it through Google.
2010 and before models use 11 digit SN and 13 digit MLB. Newer models use 12 digit SN and 17 digit MLB. As SN, MLB has logic to it, like manufactured date, place, part model, etc, etc.
Therefore, using random numbers or deleting random numbers in Clover generated MLB will probably end up failing sooner or later. Actually I found out, that clover generated exactly the same MLB in another hack (obviously this other hack uses a different SN, ROM, etc). So this MLB is probably blacklisted by Apple servers, and probably just works temporarily. And probably is the same MLB a few of us have used (it was a big surprise for me to see the exact same MLB I got a few days ago, when I ran iMessage debug to extract the MLB in this other hack).
There's work being done to make a MLB generator tool. I'm not part of it, but seems it is going to be out soon (just my guess).
Personally I'm trying to generate my own MLB, ROM and SN, with all the info gather in this and other websites.
If that fails I may try to get the 13 MLB working by calling Apple in my Apple ID.
