Delete the Nvidia ISO

During the setup of my Nvidia Jetson Xavier NX developer kit, I deleted the ISO from the board. I can’t do anything else on my board. I have tried all available ways to restore, all without success. I tried the flash, and it didn’t work either, what do I do?

What have you done to flash your device?
Are you using a native PC with Ubuntu 18.04/20.04 OS?
Which JetPack SW you used?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
