Bug description

Each time the device is unplugged and reconnected to power, it fails to boot properly. Instead of starting up normally, it only displays “JetKVM 0.4.9” and becomes unresponsive. To get it working again, I have to manually enter DFU mode and reconfigure the device.

I also tried rebooting from the interface after completing the setup, but the same issue occurs — it reboots to “JetKVM 0.4.9” and hangs there.

Could you provide the steps needed to reproduce this issue?

Also, please confirm whether the problem is limited to the device screen becoming unresponsive, or if all services including the HTTP service are affected.

The device enters an unusable state and gets stuck at the screen shown above. To use it, I must set it up in DFU mode after every power cycle. Even after setting it up via DFU mode, if I leave it idle for less than 30 minutes or unplug it from the power source for a few minutes, it returns to the same unusable screen. I have upgraded it to the newest version available multiple times, but the issue remained.

None of the services is available. Once the device goes back to the screen above, it is unusable and not detected..
