How to root Acer Z630s? I'm trying to root my new phone, it's an Acer Liquid Z630s (T04) running Android 5.1.

I can't find anything useful online, Google is filled with auto-generated pages that just give a link to some one-click-root app. I've tried a couple of them (Kingroot, Kingoroot and OneClickRoot) and they all say "no root available at this time".
Here is the link: http://android-lovers.com/Downloads/baidu.easyroot_v2.8.6.apk

It might not be the lastest version. If not, go to android-lovers.com/Downloads/baidu
