Here is what I did.
I d/l Northern_US_and_Canada_935_5809, unzip without error.
As I read, 930.5603 = 935.5809
So I copy Northern_US_and_Canada-917.meta to 935 folder, delete original Northern_US_and_Canada-100121.meta
Then I run Easy Activator 0.57.21 my favorite tools, and I got DCT Generate OK.
Then I boot GPS, 2 different TT with different navcore 9.xx both cause auto-reboot.
As an experienced for years, I stuck.
Maybe we should wait for real META
