regarding the Google Play Services issue, it looks like 2 weeks ago another customer had this issue and commented about it on Booxtor's video:

from Orb Reborn:
"So I downloaded 1.33 version of factory tool again and succeeded to install the firmware. However, still the app (google play services) was impossible to be installed. Just for the information, before I wrote the problem, mine had already had the factory installed "google play store" and it had been working flawlessly. I just wanted to additionally install "google play services" for google drive, google docs, and other google apps which had required "google play services" for full function."
he also comments about a wifi issue (i haven't confirmed this yet):
"And there is some problem about wifi connection, too. If I put the device into the sleep mode with wifi connection turned on, the wifi is automatically turned off and it is impossible to turn on wifi again when I wake it up several minutes later, unless rebooting it. Maybe it's because of malfunctioning of power management program. I've tried fiddling with settings to no avail. :-(
Now, I'm waiting for an official update scheduled in a few days, according to an Onyx associate, which will add the double page reading mode finally!"
