Tson AGX Orin Stuck on Flashing Underscore and Can't Enter Recovery Mode

Hello, I’m having a significant issue with my Jetson AGX Orin Dev Kit and need assistance.

I received my Jetson yesterday, and initially, I used a headless connection via MobaXterm, but the COMM port got lost. Afterward, I connected a display, mouse, and keyboard, but the situation progressively worsened. I now get a flashing underscore (_) on the screen and cannot proceed further.

Issue Summary:
The Jetson AGX Orin is stuck on a flashing underscore during boot, and no further progress occurs.

I am unable to enter Recovery Mode despite trying the standard method:
Pressing and holding the Recovery button during boot, but the system doesn’t enter Recovery Mode.
The device doesn’t respond to USB recovery attempts.
The system seems dead, with no output beyond the flashing underscore.

Steps I’ve Already Taken:
Tried entering recovery mode by pressing the Recovery button during boot, but the device doesn’t enter Recovery Mode.
Flashed the microSD card with a clean Ubuntu image and JetPack (JetPack 6.2), but the system still boots to the flashing underscore (microSD card has not been properly mounted as the boot device).
Checked display, keyboard, and connections; everything seems to be plugged in correctly.
Tried the standard flashing procedure with the SDK Manager, but the device remains unresponsive.
Rebooted multiple times, removed and reinserted the power cable, but still no progress.

Additional Information:
I am npot using the microSD card for booting.
No recovery mode seems to be accessible, and the screen stays stuck at the flashing underscore without progressing.
What I’ve Tried So Far:
Flashed the microSD but still no success in booting from it.
Reset the Jetson to default settings, but the device remains unresponsive.
Checked USB cables and ensured connections are secure.

Can anyone help with the following:
How to access recovery mode on the Jetson AGX Orin when it’s stuck in this state?
Any troubleshooting tips for the flashing underscore issue?
How to reflash the device if it’s unresponsive to recovery mode?
I would really appreciate any advice or assistance on how to get this system up and running again.

Thanks in advance!

Hi,
If the device cannot be flashed/booted, please refer to the page to get uart log from the device:
Jetson/General debug - eLinux.org
And get logs of host PC and Jetson device for reference. If you are using custom board, you can compare uart log of developer kit and custom board to get more information.
Also please check FAQs:
Jetson AGX Orin FAQ
If possible, we would suggest follow quick start in developer guide to re-flash the system:
Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation
And see if the issue still persists on a clean-flashed system.
Thanks!

I cannot get into the system at all

This assisted me to get into Recovery Modem but still only see the flashing _ on startup & I cannot access it via SSH from a host computer

Help - SOS - Help :-)
