E38 Operating system

[Andrew Richmond]

I have an E38 with operating system 12673958.
I want to reflash this E38 with operating system 12656930

I think this is possible without bricking the E38 as they both run the same T43 OS 24267577.

Am I correct?
Is there a later list of compatible OS's beyond 2014 on the EFI live site.
Also a list of OS for the T43 would be very handy.

Regards
Andrew

All good guys, ignore this request. Solved the issue we were having another way.
