Thank you for your update, how did you get the firmware updated without the license file? I've heard this is automatically generated if connected to the Internet.Hi
I had a similar issue to you. app etc told me no updates available but my maps were version 3 on my 3008 gt 2017 and firmware was an early one also, I took the plunge and updated my maps first to v18 and that went without a hitch so then I took the plunge and did the firmware update to the latest and it all worked fine for me. I completely understand the 'should/shouldn't i' with firmware as it is at your own risk... when the screen first went black on the firmware update i thought i had blown it but this was just part of the reset , it came back up with the correct screen, carried on updating and then i breathed a sigh of relief when it said it had finished and to remove the USB.. it then booted up fine and I have had no issues....
And I guess as I don't have one on my USB stick I have held off updating.
But happy to hear your update works
I guess the real question is, did you see any difference? I understand updating from an earlier version to newer makes it faster to switch on and respond. Just the features pretty much stay the same.
