Hello
I wrote once and still haven't received an answer.
I just bought a PR550 Mini Projector on Amazon, and need my device authorized please.
The ID is D8:A6:8F:EC:80:C2.
Can you please do it ASAP? Otherwise, I will just return it if I can't use the apps.

Also, I downloaded all this and tried running, but they don't work. Is there any other easier/faster way of doing this?

Thanks
