-Had to install 1.81 of the apk, sign-in, and then update within Google Play. Not sure why. Just an install to open the door as the current Aug 2015 build would not show the sign-in screen. Might be a severe bug. Didn't test with the version on Amazon.
-Unotelly note, don't use intercept DNS port 53 in the router, the webpage won't like it.
-If you use static IP on the tablet instead of DHCP, remember to set the DNS to your unblocker IP not your router, otherwise the webpage won`t like it. The reason for this is because I do mac re-routing using dnsmasq which is DHCP. The rest can stay a normal static setup.
Thought I'd try an updated gapps which is linked on the Cyanogenmod page, http://opengapps.org/ but no go, tptoolbox v42 doesn't recognize this, even with renaming it to a different filename, so users must use either the older kk or pa builds.
An idle thought I have about tptoolbox to wonder if when it creates the partitions if it aligns it to a 4096 boundary in order to speed up reads and writes of the filesystem. I suppose only jcsullins can answer this.
