@MotoFckr9k Ok, all I can tell you is what worked for me. I am NOT a tech expert, and if you try what I told you I did and it causes problems for you, well, it is your decision whether or not to try what worked for me.
I also have the BQ M10 HD (cooler). It came to me with android installed.
I too got stuck exactly as your picture shows. I had to disconnect my tablet, and shutdown the flash tool at this point, doing that caused no problems for me. Then, here's what I had to do.
First, I found the connection with the computer to be very touchy. I had to make sure I was using a USB 2.0 connection. But even then, I could never get it just right on my main Ubuntu computer. I ended up switching to another Ubuntu computer I have and used the USB 2.0 connection on it. That enabled me to get past the red bar problem. But then, I had two other problems.
On the second computer, when I connected the tablet to the computer, I recall having problems with connecting it "fast enough". I don't recall exactly what that problem was - sorry - but I know I had to try plugging it in several times before I got the timing just right so that the flash tool would recognize my tablet. Then, all the downloads began, except..... I got an error message about a com port not being available, and that stopped everything.
I ended up finding these instructions from BQ: https://web.archive.org/web/20180118130643/http://www.mibqyyo.com/en-articles/2015/09/16/ubuntu-android-installation-process-for-bq-aquaris-e4-5-and-e5/ . It is for a different device, but it covered my problem. The problem is that there is a package on my Ubuntu computer called modemmanager. It conflicts with a com port that the flash tool needs to use (in my simple terms). On the site I provided, BQ describes (under step #3) that you need to temporarily uninstall that package from the Ubuntu desktop computer, then go through all the steps you are attempting. So, I did that, I uninstalled modemmanager, started the flash tool, connected the tablet, all the downloads worked perfectly, the tablet was flashed with Ubuntu Touch and rebooted itself, I disconnected the tablet, shutdown the flash tool, and then on the Ubuntu desktop computer reinstalled the modemmanager package.
And now I have a perfectly working BQ M10 HD tablet running the latest stable version of Ubuntu Touch.
