Hi everyone, I have also same problem.
user interface resolution 1024x527 is not supported or compatible skin can not be found.
To solve this problem what should I do?
this is multimode.ini
[modes]
; mx=WidthMin..WidthMax, HeightMin..HeightMax,Folder
; OR
; mx=Width, Height ,Folder

m1=400..480,196..320,"480_272"
m2=234..320,400..480,"480_272"
m3=768..960,400..600,"800_480"
m4=480..600,700..960,"800_480"
m5=1024..1280,552..800,"1024_768"
m6=600..800,960..1280,"1024_768"

I have no sys.txt and I have no name tablet version 4.4.2
