Feature Request: create feat_unlk.dat from databases and system id

[armellin]

Is it possible to use the logic of this tool to create a feat_unlk.dat file from the databases and the system id?

Yes, it should be fairly easy to do. update_feat_unlk is the function that does all the work.

Besides the database and the system id, you will also need:

• security_id: it comes from <garmin_sec_id> in services.xml, but it's just the type of avionics (see this map - except that it uses hex there, while services.xml uses decimal)
• vol_id: the FAT32 volume ID of the USB drive

There is already a featunlk script that verifies feat_unlk.dat and prints its info, so it would make sense for it to update the file, too.

(If you're up for that, you can send a PR; otherwise, I can probably do it in the next few weeks.)

I am afraid that I cannot help, unfortunately I don't speak python (yet). All I can do is give all the feedback I can (G3X Touch and GNX 375)
Thanks
