my boox had the latest Arta-Tech firmware. I tried for a week to install Ubuntu, but I did not succeed. That's why I thought maybe the Arta-Tech firmware had a"blocks" and I decided to install the Booxtor firmware.
order of steps:
1) Arta-Tech Firmware
2) Utility Seaniko7 to unlock the Boox
3) last firmware Booxtor
4) Ubuntu.
For completeness I tell you that the my Boox hung in the various attempts to install and I used mgftools to unlock it. After a few days I followed the steps above.
I'm sorry for the inaccuracies on ubuntu but until two weeks ago did not even know what it was. I studied a bit and then I went to work ...
Edit: unfortunately, there remains the problem of refresh.
From the videos that you put on the web known that the display of your boox is easy to read, while my already under Ubuntu boot appears blurry and still never does refresh. I checked with the normal firmware (Booxtor): the refresh is operating normally and the display is sharp as ever. The hardware buttons on the side do not give any result ...
In the Monitor Settings I can not change any parameters, the refresh rate is locked at 0.0...
Edit2: among other things, I noticed that, compared to videos Seaniko7, when I start ubuntu I do not see the screen with the penguin and the possibility of choice, but booting directly to the desktop ubuntu ...
