1. Frozen Screen

Sincerest apologies for the inconvenience of the frozen screen. Please don't worry, your Gen-2 gauge is surely under warranty. 

If your Gen 2 28Pro experiences a frozen screen, you can currently resolve this by updating it to the latest firmware version (25A09) using the Gen 2 firmware update tool. Should you encounter any issues, please contact us, and we will send you a replacement update tool free of charge.

For a step-by-step firmware update tutorial, please refer to this link.

Before you receive the update cable, you can temporarily fix the frozen screen issue by draining the battery completely and performing a hard reset. The steps are as follows:

1. Stop charging ( Pls take off your charger from the gauge )

2. Leave the screen on for approximately 48 hours or more (very powerful & long-lasting battery indeed) to drain the power and then the screen will turn off automatically;

3. Recharge the device with your charging cable. Post-charging, your screen should return to normal.

2. Read '0' bar

This is actually rare—every gauge undergoes calibration and pressure testing before shipping. The "pressure reading zero" scenarios are mainly caused by two non-defect factors:

(1) Users over-tightening the O-ring, which blocks air pressure from reaching the gauge;
(2) The screen getting stuck on the "0" display (this can be fixed via firmware update, and we always send a free updater cable to users who report this specific issue).

Pls contact us by sending video to make sure every setup up is correct, if its true, we'll replace you a new one without hesitation.

3. Update

All of our gauges have the latest version of firmware already, no need for customers to update anymore. It's totally easy and reliable to use.
