[Jetson tx2 nx] can't find JetPack 4.6.1

Hello,

I need to reflash a Jetson device (originally running JetPack 4.6.1; a full reflash is required due to system corruption). However, I have tried multiple versions of SDK Manager and cannot find the JetPack 4.6.1 option at all. The details are as follows:

  1. SDK Manager versions tested:
    2.4.0, 2.2.0, 1.9.3

    • Versions 1.9.3 and newer do NOT show JetPack 4.6.1
    • Versions older than 1.9.3 prompt an error: “Requires version 2.2.0 or higher”.

  2. Startup flag used:
    I launched with sdkmanager --archivedversions. Other JetPack 4.x releases (e.g., 4.6.2, 4.5) are visible, but JetPack 4.6.1 is completely missing.

  3. Host environment:
    Ubuntu 18.04 (VirtualBox)

  4. Known information:
    JetPack 4.6.1 corresponds to L4T R32.7.1. NVIDIA officially announced EOL (End of Life) for the entire JetPack 4.x series in November 2024.

My questions:

  1. Has NVIDIA completely removed JetPack 4.6.1 flashing support from SDK Manager?
  2. If it is still supported, could you please provide:
    • The last SDK Manager version that fully supports JetPack 4.6.1
    • The required host Ubuntu version for compatibility?
  3. If official support is discontinued, is there an official recommended method (e.g., manual flashing scripts) to restore the system for devices originally using JetPack 4.6.1?

I am aware that manual flashing via BSP and Rootfs is possible, but I would like to confirm the official stance first to avoid further compatibility issues. Thank you very much for your help!

Hi,

  1. Yes. It not supported.
  2. Please download the 4.6.1 from JetPack Archive | NVIDIA Developer and run manual flashing scripts.

Thanks
