I succeded in using the RKDevTool after I installed the DriverAssitant to unbrick it.
Now it runs happily with the custom Armbian image I built for it because I needed the RBD (for Ceph) and the ability to create a new partition on the eMMC, also for Ceph.

Thanks,

Hello, I tried to flash a custom Armbian image on the T6, but it cannot boot after that. I tried to connect to it using the RKDevTool, but it does not recognize the board. I am attaching the screen from the serial console, and the RK tool. I tried with official images on the TF card and USB, no luck...
