Achieved root on YotaPhone 2 on 4.4.3, build KTU84L.4.4.3-S01-003-EU188.8.131.52a using Kingo Root on a Windows 8 device.
Used the original YotaPhone ADB drivers downloaded from yotaphone.com
Hope that helps
Using mine since 27/05. It spends half of the time in the pocket, the back cover was taken off a few times as well. There's dust all around the screen where it meets the cover but none underneath the actual touchscreen.
Quite bad idea for a back...
Just found this out today after finally reading the users manual:
The main colour display can be switched on by swiping up from the bottom of the screen (same as e-ink)
Not exactly tap-to-wake but close enough :)
New APK please.
Framaroot not working, will try Kingo next
