So now that I have _finally_ been able to reflash my Xavier NX back to JP 4.6.1, I am told that I cannot use 4.6.1 . So I will attempt to upgrade JetPack once again just to eliminate any chance that its me. Please advise me on the best way to upgrade. Shall I use the SDK manager (versions?) on my ubuntu host (Is 20.04 ok?), or apt or reflash from SD and which would you prefer I use JP 5.0 or 5.1? V ---

**Test 1.** Flashing freshly flashed 4.6.1 NX Dev Kit to JP 5.0 via SDKM v 1.8.0.10363 Ok Im following the steps at [Install Jetson Software with SDK Manager :: NVIDIA SDK Manager Documentation](https://docs.nvidia.com/sdk-manager/install-with-sdkm-jetson/index.html).

This is what I found. I can use SDKmanger to flash jetpack 4.6 or jetpack 5.01 successfully including all extra tools to Jetson NX SSD. I found if I use manual config after flash it works better than trying to config user and passwords from SDK manger. I have also found that I haven’t been able to get Jetpack 4.5 or 5.0 to flash using SDKmanager ---

Yes I power-down the Jetson then set the jumper then reconnect power then connect the USB cable to host computer then run SDKmanger on host computer. I select Jetjack 5.01 and developer tools and select the Jetson Xavier NX developer kit version. Once the OS has downloaded and built I select manual config and flash to NVMe ---

Well I have very good news. Today I ran my \>10th sd flash install of JetPack 5.0.1 on my NX Dev Kit and low and behold it worked! (so far) . It was very slow booting up and the fan is working really hard, but I do have my focal 20.04 Ubuntu start screen! As of right now it seems to be struggling with some update installs. Keep this open for a bit longer until I have time to test further. If this works out, the next step is to see if JP 5.0.1 and Riva 2.2.0 will play nicely together those results will be posted in the Riva section of the Forum. ---
