Default Generic fw

I have two questions so I'll ask them both rather than clutter up the forum.1 Does anyone have a truly generic copy of fw 4.1.2 (.254) my device says its generic but flashtool says it on an EE version I'm trying all possible routes to change bootloader unlock allowed no some people have reported it changing itself after an update. Alternatively does anyone know how to alter build prop to make PCC repair my device to generic. I presume if my device was to identify itself as a generic SP then PCC would update or repair it accordingly.

2 Has anyone come across an app called sim lock its one of the system apps and disabling it via root uninstaller seems to have no effect on the handset operating.
I'm on .254 locked to EE (UK) just wondering what it does surely it can't be the sim lock on the device?
