yes it is i just done it. good thing you can erase opuses and re-write em lol. was an old rom11. i basically altered it in nagra then saved it as a bn10 image then saved. renanmed .bin after that and when writing just called it a rom10 when asked
It wont auto-update until someone fixes the OPOS program to cope with the current keyroll (or patches the Rom10 image file embedded within the program).
There's no advantage to using a Rom11 image over a Rom10 image and it may not work with all OPOS versions. Any version which enables bugcatchers may give problems with a Rom11 image.
