My TX2 device does not boot after flashing with

I generated a clear massflash blob as described in README_Massflash.txt (Jetpack4.4.1) on my development Ubuntu 18.04 Linux PC. Copied the archive to new directory and untar it. After successful flashing the device does not boot (No nvidia splash screen). The logfile shows no problem everything succeeded. Flashing the device with and the same image is no problem. I don’t know what’s the difference between flashing with and I did everything as it is in README_Massflash.txt

Please try this package for JP4.4.1:
