Tried installing Jetpack 7.0 to new M.2 ssd with the sdk manager and now I have a continuous reboot prosses that will not boot the Jetpack ISO on new ssd. This may be a UEFI setting issue or bootloader. I have no experience with bootloader. I tried resetting everything to default and still could not get past the Nvidia logo screen then the monitor would disconnect. Firmware Version 38.2.1
Please try to flash Jetson with sdkamanger from another x86 host PC.
I’ve tried the SDK Manager multiple time and would not boot IOS and either get stuck on a shell> screen or continuous reboot. So far I’ve found this command, sudo ./l4t_initrd_flash.sh jetson-agx-thor-devkit internal, I’m fairly new and not use to messing around with the bootloader cause i believe it is corrupted. I type that command in and it says not found.
Hi,
Just to clarify. I believe your sdkmanager attempt didn’t start the flash process at all…
So basically you just did nothing on your board at all.
Please take a screenshot for what did you see on your sdkmanager…
And please stop trying this for now and just focus on sdkmanager first. They are doing the same commands actually but sdkmanager will help you do everything.

So once I turn it off then turn it on the Jetson Thor is stuck in a loop of rebooting after Nvidia logo screen.
Hi,
Please enable the serial console log by connecting the debug type C port on your Thor devkit, and then follow similar steps as below page to dump log.
And for sdkmanager, there is a “EXPORT LOGS” button in the GUI, please clock it and share out full log. It should be a zip file.

There is no update from you for a period, assuming this is not an issue anymore.
Hence, we are closing this topic. If need further support, please open a new one.
Thanks ~1022
Hi,
For the UART console log, please resize your terminal and capture log again.
Each line from your log got truncated.
