Hi all. Any idea how to root the device?

Igor: Thanks for the info, I will order a new T6 which I assume will be the v2 revision. Perhaps things will work out better - let's see.

Is there a way for me to build my own deb package?

Works just fine with Armbian_24.11.1_Bigtreetech-cb1_bookworm_current_6.6.60_minimal

thanks for your reply, i'm complete novice in this, do i need to write it to boot section of rkdevtool like screenshot bellow ? i didn't soldering the sdcard reader into the pcb yet, was hoping if there's a way to run armbian without doing any hardware modification.
