A reset can reboot your product or it can clear all product settings and revert your product to its original out-of-box state. If you encounter issues like automatic shutdown & reboot, frozen on Nebula logo, colorful lines or unable to power the device on, please try to factory reset the projector. 

To Restore to the Factory Default Settings:

Note: This reset erases all settings and data on your projector and reverts the product to its default out-of-box state.

• Power off the Mars II but keep the lens cover slided down
• Press and hold "Volume+" (on Mars II) and "Power" button (on remote) simultaneously for about 4 seconds, and you will see the Android's robot logo appear on the screen.
• Press and hold the "Power" button (on remote), and click "Volume+" (on Mars II) ,the Android Recovery screen appears soon.
• Press the "Volume-" button to skip to "Wipe data / Factory reset" option.
• Press the "Power" button (on remote) and choose "Yes", the system will automatically jump back to Android Recovery screen after factory reset is done.
