I had to do a factory reset because of the UI system has stopped. Aparently it was cause by Google autoupdate and my battery problem. I tried all kind of programs in the end I hard reset the phone. Now I am stuck because of the factory reset protection, the phone connects to internet but not to google servers. It doesn't work in China whiteout Vpn. Tried to follow this article and many others, no succes. I have internet, Vpn but no wired connection. Is there something else I can try?
