My device isn't play certified

nah i did both already

Did you enable developer mode successfully?

I did it right after installing FydeOS

Do this and reinstall open gapps. As long as you enable developer mode, it works for everyone.

i did it already

You just did it in a wrong way. I don’t see anybody enable developer mode and can’t get it to work. Take a video how you do it if you want help.

i did it again and it worked

My CPU s evil even i navigated to the sign in page it still wont response
