Still Unable to update

[Jextra]

I'm afraid I'm a bit dense, I go through the update procedures. The zip drive and the file is there, I cannot get it to install, I always get a message "go to app store"? I do not get the indication that the update is taking place. Please just a step by step so I can find out what I'm doing wrong. I follow the instructions to the letter.
Thanks John W8NEE

The firmware upgrade procedure is described step by step in the openSPOT's user manual at https://www.sharkrf.com/products/opensp ... cy/manual/

Please see the Firmware upgrade section.

I follow it to the letter without good result, otherwise why would I post this?

Can you please write which step does not work for you?
