There are more and more users and smartphones on the market with Ubuntu Phone, but that does not mean that there are no errors in their versions.

Once written it will be returned to us the nickname of the terminal which is also the name of the version or series of compilations that the development team has created. Now, taking the nickname we will write the following to know all the stable versions for this device.
ubuntu-device-flash query --device=<b>"sobrenombre-terminal"</b> --channel=ubuntu-touch/<b>stable</b>/<b>meizu ( o BQ).en</b> --list-images
The resulting code that the terminal will issue will be the total number of updates available for the terminal and the reference number of versions we have available through the stable Ubuntu Phone channel and we will use this to install the old version we want to install or the one we want to return because we liked it at the time.

ubuntu-device-flash touch --revision 10 --channel=ubuntu-touch/stable/meizu.en o bq.en
This information is useful for future information as we may come across some update that fuck the performance of the terminal and we want to go back to an old version. As you can see, Ubuntu Phone can do things that a normal user cannot do with Android or iOS.
