I had a heck of a time updating my new flysky g7p. I searched everywhere for help. Here is the simplest way to do it. Make sure you have a fast charge usb c cord. Turn on tx and go to update. Plug into the computer. Once the computer beeps and recognizes the tx a window will open for flysky. Then download the assistant. It will open and it becomes a breeze. If you have issues with assistant opening, it may be firewall protection. Just use hotspot from your phone. I hope knowing this order works will save you the hrs of headache it cost me.
