-Both Camera and Flash
-Screen Mirroring
-Basically everything

What dosen't work

-Nik-gapps-pico-arm64-11.zip (Propietary)(yes it is arm64 , and yes it is not gapps)

How to Fix the “Device is not Certified by Google” Error

[Your device will still say it is uncertified in the Google Play Store settings.
This is normal. All this fix does is white-list your uncertified device so you
can still use Google apps and services.]


Install the Device+ID.apk (Included)

Open the app , Tap the Google Service Framework (GSF)

Copy it

Go to this website-


Paste/Copy GSF code in the box

Complete captcha (sorry dosen't work for robots)

Register (The box goes red , it's totally fine)


After a few mins you should be able to sign in

(Don't worry , it will keep saying that not certified but after
a while it will let you sign in, and turn off notification for play
protect to remove annoying notification)

For more info-

1.Gapps Flash Error70 No space
2.Device Is not certified error

1.Maps keep closing , Though maps-go , waze work fine.(Probably a google issue)
2.Bootanimation can be changed
3.Play Services can be broken

For some reason the files were not attached here but instead to this
