Let's check your gate.

If your LagKing stopped working, or is acting strange, this page pulls a small diagnostic snapshot straight off the device and sends it to us. No cable, no app. Takes about a minute.

1. Plug the gate into a USB-C charger.

If the battery ran all the way down, the gate locks itself off to protect the cell. Plugging in power is what unlocks it. Leave it charging for about 15 minutes before you continue.
2. Flick the power switch off, then on.

The status light should come on. If it does, great, the gate is awake.
3. Close the LagKing app if it's open nearby.

This just frees things up so this page connects cleanly.

Nothing is sent until you review it and tap Send. The device snapshot has no personal info, just counters and voltages. See our privacy policy.

Reading your gate…

Keep the gate powered on and nearby.

Report sent.

Your gate's diagnostic snapshot reached LagKing support. Nothing else to do, so you can close this page.

We'll review what your gate told us and follow up. Haven't heard back in a couple of days? Reach us at support@lagking.com.

We couldn't reach the gate.

That's okay, let's narrow it down.

Try this checklist first

Is it plugged into a USB-C charger? Give it 15 minutes, then flip the power switch off and back on.
Is the status light on at all? If it's completely dark even while charging, the gate may not be booting.
Close the LagKing app on any phone nearby, then try Connect again.
Use Chrome or Edge on an Android phone or a computer (iPhone browsers can't do this step).

If the light never comes on and it won't connect, it's likely a hardware fault, which is an RMA/bench case and we'll take care of you.
