Firstly which version of the operating system are you running? If its one beginning with 4.something do not flash the kernel, itnwas designed for the previous version and will cause your tablet not to boot. If you are running the version beggining 3.something and dowloaded the one click install from the first post in this thread the do the following:
gain root then type
/root/install-xrandr-kernel
Then reboot
Hope that helps
