Enable multiple sessions on lockscreen

For me, it takes around 2 min ,just the time to completely download the file , then ´failed to...´
At the same time on the screen tablet, 10s after the start it exits from fastboot to return on thefastboot ,recovery menu

I have exactly the same result than UKphil when using the same command Line for m10 fhd migration :
Waiting for device to enter recovery mode ...
2.47 MB / 104.46 MB [__] 2.36 % 42.74 KB/s 40m43sFailed to enter Recovery
Please if someone finds a solution, send us the infos

First, thanks for all the great work made on the OS by the ubports team, it's wonderfull !!!
I would like to see juste a little improvement of the design, for exemple :
return of translucidity of background of password in lockscreen with the clock and date on m10
possibility to start on desktop mode on the tablet (allowing to have shortcut and folde on desktop screen)
improvement of design of the scoopes for my video, my music...(size, presentation..) a little like it was on Ubuntu edge(or like the scope cinema by daniele)
a new scope my doc with the same design
a home scope highly customisable
thanks for the translucidity of the scoope it's perfect
different theme for the unity, like unity 7 (translucidity) and others
different animation effects when opening app and having one gesture to close directly an app
....
perhaps you have best ideas to make UT Ubports the most beautiful and customisable OS
thanks for all
