Checked Armbian_22.02.0-trunk_Rk3188_bullseye_current_5.10.96.img changing dtb that ususally gives me partial function on Minix Neo X7 (Ugoos, CS968) without luck (no boot, no led), same thing happened with latest LibreElec RK3188 images, no boot, no led , sometimes kernel panic. With this image and included default .dtb (rk3188-ugoos-ut2.dtb) boot from SD works ok: Armbian_21.11.0-trunk_Rk3188_hirsute_current_5.10.63.img.xz Also internal USB-LAN (RTL8152) works ok, No Wifi , No BT (GPIO3_23 conflict with ethernet) will debug more about this and come back later.

I was in similar situation with my Neo X7, recovered installing twice original Android (250) using Factory tool V1.63 (previous attempts with V1.27 failed) after 2nd update Armbian and LE in SD Boots ok ( No ETH No Wlan ). Firmware: X7-rk3188-250.7z Driver Installer: DriverAssistant_v4.5 Windows Tool: FactoryTool_v1.63
