Hi John.
I assume you are referring to the USB stick upgrade method?
Copy the file to the root of a pen drive. Do not change the file name.
Put USB pen drive in spare USB port on PAW(see note)
Boot up PAW and connect your tablet or phone to the Wi-Fi hotspot when it becomes available.
Open browser on tablet/phone and go to 192.168.1.1, you should now be on the homepage
Click the updates button
Click Check for updates
If one is found on the pen drive the Click install
Make cup of tea and drink it (biscuits optional)
On tablet check, if Wi-Fi hotspot has returned. If so connect to it again
Back to the browser on the tablet and check the home page to see if the version is correct, and all is working.
Note: it is OK to remove GPS or ADSB dongle to get access to a USB port, but not the smaller Wi-Fi Dongle.
