Set the DPI to 320 using Textdroider :http://goo.gl/m2PHZr
Enable softkeys with using Softkey enabler: http://goo.gl/1l3Gyl
I used the following Xposed modules:
Xposed installer: http://goo.gl/JEu7Sr - main installer.
App settings: http://goo.gl/ifxLq3 - Find systemui in the list and change screen (dpi) to 600x1024 and any other app you would like in phablet mode (camera, keyboard, hangouts, gmail)
Phab7: http://goo.gl/6Mq5ri - Check Phablet (this fixes some landscape wackyness with the softkeys
Play store fix: http://goo.gl/xx9CNG ensures there wont be play store issues with the DPI
After all this reboot.
I also disable all the hardware buttons form the settings built into Omni.
