I tried the new rom7 file in dublin on a dbox and the keylist generated had 1 digit wrong.
I now think a better option for me is to simply rename your current one to magrarom7.bin and replace.
Or if you are in an unaffected area rename the new one to magrarom7.bin and stick it on.
The reasoning is that the CC could revert to the old keyroll method and then you would have to transfer the old one back on again. But this way means you can rename via tuxbox commander. When renaming in tuxbox you can just press up or down on the first letter, hence why I picked magrarom7.bin
