Jetson Orin Nano won't boot after switching between JetPack versions - Black screen issue

Hello Jetson community, I’m having a critical boot issue with my Jetson Orin Nano Developer Kit after trying to switch between different JetPack versions on SD cards. What happened (chronological order):

1. ✅ SD Card #1 with JetPack 6.2 - Worked perfectly

2. ❌ SD Card #2 with JetPack 5.2 - Stuck in boot loop, couldn’t start

3. ✅ Back to SD Card #1 (JetPack 6.2) - Still worked fine

4. ❌ SD Card #3 with JetPack 5.1 - Didn’t work

5. ❌ Back to SD Card #1 (JetPack 6.2) - Now BLACK SCREEN! Fan spins up then stops, then runs continuously. Screen shows only a blinking cursor/dash.

My original goal: I need to run JetPack 5.1 to use an IMX519 camera which according to the supplier’s documentation is only compatible with JetPack 5.1 and NOT compatible with JetPack 6.2.

How can I reset the bootloader to factory state so I can get JetPack 6.2 working again?

What’s the correct command to flash only the bootloader without installing a full OS to eMMC?

Hello,

Thanks for visiting the NVIDIA Developer Forums.
To ensure better visibility and support, I’ve moved your post to the Jetson category where it’s more appropriate
