Jetson nano boot error

I have a problem with my jetson nano boot error. To be more specific, when booting, a log like the following appears, then the Jetson Nano reboots, and this repeats infinitely. Before I last used it, I didn’t do anything and it happened one day when I turned on the Jetson Nano to start working. I don’t know about this problem, so I can’t do anything.
I Have a SD card reader, so I can connect it to my laptop and access internal files.

– version
jetson nano 4GB developer kit
ubuntu 18.04
jetpack 4.5

Hi,
We would suggest use SDKManager to re-flash the system to Jetpack 4.6.4. If the developer kit is good, it should be working. Please insert SD card and re-flash the system through SDKManager.

Thank you for your suggestion. Then, I have a question. Will all the files inside be lost when I re-flash the system through SDKManager?

Now, I can’t access ubuntu, because jetson nano reboots infinitely

Hi,
Yes, the rootfs is flashed to SD card so the files will be lost. Please back up the files before re-flashing the system.

I want to use that suggestion last. Is there any other way? T T
