Please take into account that at least 1 person had some info out there about his Legend 1.11 update problems. The thought process was there were old drivers in the 1.11. update package at some point. The guy posted his findings and also a link to the drivers. It was not something a lot of people could do, even though it was simple if you are fairly proficient with computers. It involved downloading a new driver package and installing that on your PC. After that you redo the Nokta update.
As with all things electronic, factory default the Legend BEFORE and AFTER you do the update. But before you do write down any settings you want to keep so you can restore your customizations.
Silicon Labs CP210x USB to UART driver was the believed problem. There is a link to more updated drivers. The link is below:
The CP210x USB to UART Bridge Virtual COM Port (VCP) drivers are required for device operation as a Virtual COM Port to facilitate host communication with CP210x products. These devices can also interface to a host using the direct access driver.

for Windows users you would want to grab the
CP210x Universal Windows Driver, unzip it and then install it. The Legend update Tool zip file has a directory in it but that one contains the older driver that potentially could cause problems especially on newer windows versions.
I'm taking a pretty deep dive on this. But, from what I discovered Nokta used an older Legacy version of the Silicon Labs VCP driver in their package. That particular one was able to work flawlessly with WinXP/Win7. But not so much with Windows 10 and 11. I can see the guy's logic on this.
For even more of a deep dive, the Nokta version of the driver included in its update tool is 6.76 which supports Win XP, Vista, Win7, and Win8.
The newest is 11.3 and as per their release it says
OS VERSIONS
-----------
This package provides the CP210x VCP driver for the following versions
of Windows:
- Windows 10 version 1803 and later (x64, x86)
- Windows 11 (x64)
I can go deeper on this but ultimately it would depend on what OS you are running. Anything less than Win 10 you will be fine with the Nokta update. Win10 and up maybe a problem due to the driver being old in the Nokta package.
Like mentioned, this is a pretty deep explanation of what could potentially be a cause of weird behavior after updating the Legend with a PC of Windows 10 and higher.
Attached some screen shots to help visualize what the issue is.
First one- Inside the Legend Update Tool you can see the Cp210x drivers folder.

Next we take a look and see the version as mentioned above. Not ready for anything above Windows 8.

In this next one we take a peek inside the Silicon Labs windows Universal Driver that is compatible with Windos 10 and up (x86 and x64 version). Disregard the ARM directories as that is a different chip architecture we will not be using if on a laptop or desktop PC.

In an ideal world to be safe it won't hurt a thing to install the Universal Windows Drivers, reboot PC and then try the Nokta Update again if you are having issues. I can't see where this would harm anyone's machine- I've looked it over well enough to say its safe due to coming from the manufacturer of the chipset inside the Legend that communicates so updates can happen. I wish I could remember who the Youtube guy was(Andy Williams, Thanks to oldkoot and his video below my post), but credit goes to him on this. I'm just trying to break it down for everybody else. I hope it helps you.
