Hi @robin-ceilix,
welcome to the StereoLabs community forum.
I tried that several times, however lsusb always emits 0955:7020 and not the desired 0955:7532 or something similar.
0955:7020 is the NVIDIA Corp. L4T (Linux for Tegra) running on Tegra USB device mode gadget, which is exposed by the operating system after a normal boot. So the device is not failing to be detected, it is simply booting into Linux instead of entering Force Recovery mode. A second confirmation is the power LED: when the ZED Box Orin is really in Force Recovery mode, the power LED stays OFF and nothing boots.
For your model, the Jetson Orin Nano 4 GB, the ID to look for is 0955:7623 NVIDIA Corp. APX.
Given, that I have no access and that entering the recovery mode does not work, what am I supposed to do?
The second method documented in the flashing guide (sudo reboot --force forced-recovery) requires a login, so it is not usable in your case. The solution is the alternative procedure that boots the ZED Box from an external live system, described here:
The important point for you: that USB key is flashed with a complete L4T system, so when the ZED Box boots from it you are not using the internal disk and the forgotten credentials are irrelevant. The live system uses the factory default credentials, username user and password admin. In short:
- Prepare the USB key (32 GB or larger, USB 3.0) on an Ubuntu host PC with the flash script matching the JetPack version installed on your device, following Setting up the USB Key.
- Power off the ZED Box, plug the USB key into the single vertical USB Type-A port, then power it on and wait for the boot from USB, it takes a while.
- From the live system, run
sudo reboot --force forced-recovery, then verify with lsusb -d '0955:' on the host PC that 0955:7623 is now listed.
- Remove the USB key and flash the device following Flashing the ZED Box Orin model.
If you do not have a display connected to the ZED Box, you can drive the live system through the USB serial console: Remote access via Serial Console.
Please note that flashing erases the internal disk, so all your data and custom configurations will be lost. If you need to keep them, once you are booted from the live USB key you can mount the internal NVMe partition (usually /dev/nvme0n1p1), chroot into it and reset the password of the user account with passwd; in that case there is no need to flash the device at all.
One last thing: the automatic recovery method works reliably on the ZED Box Orin generations with serial number starting with GTW-ONX1- or GTW-ONX2-. Your serial number starts with GTW-ONA1-, so please send the complete serial number to support@stereolabs.com and we will confirm the exact procedure for your unit.
