rkdeveloptool shows device, absolutely no command works

[juliaszone]

Hello, I have a NanoPC T4 with an RK3399, Recently I was able to use rkdeveloptool just fine, but yesterday it would not work anymore, absolutely not. Every command failed, even though it was listed on the devices list. I tried 2 computers and one VM, multiple cables and usb ports but absolutely nothing seemed to make it work. The exit code is always 1, there is nothing useful logged and there is nothing in the dmesg.

This is what I am always getting, no matter where and how I connected it. I'm at a point where I seriously don't know what to do anymore and I feel like I'm about to go crazy. Is the board defective? Because I honestly just can't think of any other reason, especially since there is no logging at all
