Normally we suggest using the Settings menu to change your Loop frame's settings, reconnect it to Wi-Fi or factory reset it. In certain cases, like during setup the that menu isn't yet accessible however. In those instances you'll need to instead use the Service Menu by following the steps below:
1. While your Loop frame is plugged in and turned on, pull the stand out from the back of the frame. The stand snaps into place so don't worry about pulling too hard and breaking something.
2. Once the stand is out, place your frame screen down and look for a small button next to the USB port. Press the button to bring up the service menu. You may want to use a paperclip or pen to press the button since it's recessed.
3. Now flip the frame on its back, you should see the service menu on-screen.
