I went back and installed the original Ubuntu Touch with the SPFlash Tool and was able to update to the latest UBPorts version using the desktop app with no issues after that. Thanks for the prompt feedback everyone.
With BQ formally out of business now, it will give my M10FHD some extended life. I still remember how excited I was when it arrived from Spain here in the US way back when.
I will send a donation to the UB Ports Team as soon as I finish checking everything out.
@marathon2422 I have a BQ M10 HD running OTA 15. It connects to my Panasonic TV with my Blackberry Playbook HDMI cable. Video playback is great, but no audio over HDMI. All you get is audio from tablet speaker. Such a shame.
it is possible to reach system settings via the battery indicator, so you can update to the latest version or change channels. Touching the "about" icon while in system settings will cause a crash.
