So I bought the 2GB Nano DevKit today and it worked fine the first time. I was trying to install the newest JetPack for the 2 GB version but the installer window disappeared at the last step before I could start installation, so I just disconnected the power. It rebooted fine but I ran out of time then so I had to power down the board again. After that it stopped booting at all - constant black screen.
I reflashed the SD card (SanDisk Ultra 32 GB) 5 times already - 3 times using Etcher and 2 times using Win32 Disk Imager. Also tried another SD card twice (random 16 GB Kioxia). Nothing works. I’m using a 3.1A 5V USB-C power supply.
Here’s the serial console output:

Did I break the board somehow? Is there any fix possible?
