All sorted now. The magic device tool seems to flash to OTA-14 but using the next method on the list worked perfectly. Weird.

I have followed the instructions on this page for flashing my M10 with the magic device app thing. I simply end up with a copy of OTA-14 and nothing is wiped off my system. Could someone please advise how I switch to the UBports version of UT?

Thanks
Gareth
