I bought an ONDA v919 Air CH few weeks ago,It's a new tablet using Atom X5 Z8300(HD graphics Gen8)
When I use 5.1-RC1(x86 or x64),The device got a blackscreen after root:androidx86:
When I use the 6.0 or 4.4 r3,It even got a blackscreen after I choose the live boot in grub.......I can't get a dmesg or go to the debug mode
maybe it is a graphics problem
I search for cherry trail but there is nothing useful
But telcast x16 Pro have a perfect dual boot system(Win10 and android5.1)(also a tablet from China)
Oh,when the 5.1RC1 got a blackscreen,the reading LED on the USB stick just light and didn't flash
