I purchased a reComputer J4011 to develop an AI voice recognition edge device. While installing and setting up the Wi-Fi/Bluetooth module, the device driver did not function properly, so I changed the BIOS setting from ‘Device Tree Mode’ to ‘ACPI.’ However, after this change, neither the BIOS screen nor the boot process works.
During boot, pressing the ‘Del,’ ‘ESC,’ or ‘F2’ keys does not work, and I am left with a black screen, unable to do anything.
• Is there a way to reset or restore the BIOS settings to default without damaging the currently installed OS and system?
• If such a method is unavailable and the entire system needs to be reinstalled, what is the recommended procedure for doing so?
I haven’t tried that yet. I lost the HDMI output after going into BIOS setting / Device Manager / NVIDIA Configuration, and ‘F9=Reset to Defaults’. After rebooting my HDMI stopped functioning. I am currently only able to get back in to the BIOS via serial-debug connection and SSH for system access. I tried flashing the system to Seeed’s Jetpack 6.x to see if it might fix the problem, but it did not. I have been looking through the Wiki and other system docs, but have not found any information on how the BIOS should be set. This is a basic Industrial J4012 16GB and no BLE/WiFi card has been installed.
Yes , I have seen this question b4. SO you are NOT the first one to experience it. You may need to place a jumper or something for the “restore”, DID it come with JP 6.0 ? Only flash what it came with originally , I believe its an overlay or DTS file issue.
Maybe seeed support can chime in with a fix process.
The WIKi is the best place to start looking though
Thank you for your reply! It came with JP 5.1.x. I have tried to flash it back from Seeed’s package, but it fails with output below. But JP 6.0 and 6.1 flash complete successfully on same host and USB cable.

Cleaning up...
Yes, I have seen a plethora of posts on the only method to reflash wit a specific Ubuntu host and version to get everything to stick correctly.
Users have tried using the Nvidia SDk stuff even only to fail at the last steps or something, frustrating like that.
Follow the Wiki to the letter… and it can be done.
Something with the Overlay or DTS and the HDMI , I think was a root cause and Doing Update all , vs just update packages… YMMv

FWIW , it is a VERY nice unit, and Powerful not to mention $$$ so I get the urgency, maybe seeed Support can chime in and provide a direction for your case specifically.
Well I loaded a fresh version of 20.04 on different laptop and new USB cable. Same timeout issue with Seeed’s JP 5.1.1, even following Wiki to the letter. I tried both Method 1 & 2. I don’t think it’s my hardware or cable because Seeed’s JP 6.0 and 6.1 successfully completes the flash. Still no luck on finding any factory bios settings for carrier board or Nvidia Jetson NX. The experts over at the Nvidia forum say there is no such thing as doing a factory reset and that you must flash the Jetson NX to get back to base configuration. I too believe the issue is with an overlay or DTS, but don’t know where to look. Hopefully Seeed support can point me in the right direction. Are they actively monitoring this forum on a regular basis?
So did you use the image on the wiki or the git hub… Check that.theres a difference in what’s packaged with it ,if I recall . There’s a post to that effect on here also.
The version of Ubuntu maybe it was , your close .
