How to flash format

So fair warning before I continue these phones do not operate with a sim so you will not be able to use cellular. If you are hoping that formatting it will give you a fully functioning phone then you’re gonna have a bad time. Also the demo software can sometimes be hard coded in the phone and you may need to find a way of force removing that (it can depend on where the demo was from ). That being said here is an awesome walkthrough for that you may need to format the phone.

1. Ensure the device is powered off.
2. Press and hold the Volume Up + Bixby + Power buttons at the same time. Release all buttons when the Phone vibrates.
3. From the Android Recovery screen, select Wipedata/factory reset.
4. Select Yes.
5. Select Reboot system now.
