VK815 rooting help

I've seen reports of the VK815 being rooted and would like to root mine. Is there someone who has a VK815 and has rooted it who is willing to share how they accomplished it?

I have 'adb' available and working, the developer mode enabled, and can talk to the phone. Trying to attain superuser from the 'adb shell' doesn't work because the 'su binary' is missing. 'adb reboot recovery' gives the ''dead android' and the 'power/volume -' key combination results in a normal boot.

Thanks,
Jim
