Awesome video, really smooth step by step, easy to follow! After almost an hour of attempting this multiple times last night i finally gave up, but after watching this video it only took me 10 minutes! Thank you for this quality guide! 10/10

Best one yet.

very clear worked very well

I followed the exact steps on this video and from the manual also. I do not get a prompt to update firmware at all. The scope just turns on and nothing. I just bought the thor 4 so I assuming it already has the latest firmware but I'm not sure. I'm just following the manuals instructions exactly and it tells me to update the firmware first thing. I've tried different SD cards and just about everything I can think of.

How do you download to an Apple computer then to the SD card?

Followed this step by step to a T . 640 2.5x will not update for me ? Tried 2 cards

Downloading firmware ??? Windows 10 and above or 10 only? I happen to have W 10 now but my next computer likely won't and it's coming soon.

I just received my new ThOR 4 (purchased from ATN website). I did everything as described but I don't get the "firmware update?" request box when powering up the scope. Does that mean its already up to date.

Why doesn’t my ecompass change direction it’s stuck on north.? Anyone

Why is it that SD card icon in the upper right corner, sometimes lights up red and sometimes green?

Why if my x and y are zero? And idk what to do

How do you update a LT ?
