It is possible to get Google Play Store perfectly running on Acer CB C720P,
off the USB 3.0 port using a USB 3.0 bootable stick with the recovery rom for Acer Chromebook R11 - it needs adjustments, & a version of Chromium OS above 55 like https://www.dropbox.com/s/kebu46foi6quu96/Camd64OS_R55-8777.0-Special.7z?dl=0
(use WIndows Diskimager to map it to usb stick, then expand the data partition file system to use up all the disk)
A great how-to for this method & the chromefy method is in post 163 by Hnk1,

Request : Can you put the link (one I mentioned above, post # 163 )in the first post mate ? So more people can install it on their CB and it will be easier to see. What you reckon?
