    I tried this on my rooted Galaxy J7 Pro SM-J730G, flashing both your Firehound file and GAapps nano from TWRP. The OS loaded great, but once loaded, the camera wouldn’t stay on, and it would only hook up to the internet by going into the settings and typing in a Static IP address, would not find the connection automatically. Did you experience the same issues? Do you know of other custom ROM’s for this device? Why is there so little out there?? Thank you for your help…
