In other words, using other homescreens is not possible in version 2.03.
Sorry, but I disagree. In that link that have written @pcristi I can see the following:
<<With disabled security L1 multiply Launchers working normally at new firmware.>>
So I guess that should be a possible solution.
Knowing that this may work, who writes the updates may make the corrected actions
I still do not have the q10pro, but I suppose there are no ssh connection problems between it and other devices. It is another way to make the necessary modifications without using adb commands
I have ssh connection with no problems but I not rooted Q10pro and I can't modify build.prop file.
I use adb commands with no problems. I have a new home screen.
Thanks @pcristi
