AEP Condiut cannot be accessed

Hi Forum,
i start the new thred here to discuss my issue with the AEP Conduit.
What i did to get that issue:

1. power on the Gateway.
2. Only Power LED is on always, there is no any signal of other LEDs. The issue i noticed before opening the Device is, the 3 LEDs were on. As soon as i put my hand on the blue shell of the APE Cnduit device, only PWR LED is on. As soon as i leave my hand away from the device’s shell, 3 LEDs are back.
3. Connect the USB to the debug port behind the front panel.
4. Setting the TerraTerm as required.(which did work well before.).
5. See the USB Serial port available to be connected. Type in User name and pass, click Enter or any other keys. No response. Black screen only.
5. Push and Hold the reset for(many times, 5s, 30s, 1mins).
6. Power off the device, power on the device again, reset again and again
7. nothing changed, only Power LED is on always, No any response from debug port.
8. Uninstalled the Lora card inside of the device. Tried all the flows above. Same problem.

In the Device, there are 2 Atane connecters not tied /fixed, I doubt, that they shorted the power or something related, which distroyed the U-Boot?
Is there any other method to go into U-Boot mode? We got blcoked by that issue.

Thanks for suggestion in advance.

Best Regards
JJ

Hi *,
after removal of the Battery and restart the device, i can get the following information via the TeraTerm. And it stacks there without further progressing

JJ,

Please open a support portal case at https://support.multitech.com for this. The odd behavior you are seeing with the LEDs when you just touch the device looks like there is something wrong with the board. If this is indeed a defective device, you can get it changed out for a new one.
