Gemini Android 8 upgrade

We added some instructions to perform a manual upgrade to Android 8. They are available here.

Please note the upgrade is currently for Gemini 4G devices only (both x25 and x27 models), not for Gemini WIFI devices.

IMPORTANT INFORMATION for users in Japan on the NTT DoCoMo network: we had some reports that the network is not detected by the Android 8 firmware. We are investigating - please wait to upgrade your Gemini until further information is provide.
