@davidoclubb Took a few attemps but this is what worked for me. Using the link provided earlier, under Installation Instructions you will find 'Command-line tools'. I used the .dd one. Do take note of the 'Note' re image extenstion and device name.
In Summary
- Used balenaEtcher to flash UT image to sd card
on PC - On tablet run UT via sd card & download latest
UT image - Re name image
- Check eMMMc name using lsblk command
- Then sudo dd.... etc
- Power down, remove card
- Reboot
I am sure there are easier ways but I am no expert so can only tell you what worked for me.
Hope this helps
