Unable to upgrade from 1.11 to 1.17

[neilpw]

Hello,

Has anyone else had trouble to upgrade their Legend to 1.17?

I have spent the past hour looking at Nokta and YouTube videos on how to do this, and had planned it out (16 steps!). But when I tried to actually upgrade my detector I got stuck at the point where you press on the up button and UP appears on the screen. At this point you are supposed to be able to see an Update button which you click and see the % progress bar move to 100%. But for me, it did not show me the Update button?

Thanks, Neil
