Hello, I am talking about going to the Setting of Android and looking for adding accounts. And add the Goolge account.
If you cannot register Play will not work as well.
I was in the past working on installing Google Services here is the thread, (Terzon helped me).
But when I tried again later, after having loaded the Android image 99 and using the same procedure as described in the thread I could not make it register anymore.
It locks when I was trying to register my account. Probably your white page.
Also note that DragonBoard has no licence to use the Google services.
I also gave up, since, in my opinion, the Google services slows down the power on and there are other way to find apps.
