MT:
I rebooted numerous times after the flashing apparently failed and I was greeted with a very strange looking (missing fonts I presume), and completely unusable, display.

From what I've read many vital steps come during and after the CMT flashing phase (such as setting up the filesystem).

It's strange how this error effects those with the 'telephony functions disabled error' (including mine), even more strange as why pushing the battery in hard eventually fixed the issue.
