@jock The SD card slot is physically broken and does not work. My problem is that the Multitool will not boot. I’m not sure why, but the box either boots into Android Recovery or starts Android normally.

Hello, I need help installing Armbian on an MX9 5G TV box. The box is based on an RK3228A SoC and uses NAND storage. It does not have an SD card slot. This is what I did: I first tried to boot the Multitool from a USB flash drive, but it did not work. The box always booted into the Android recovery screen. I then read that, for boards without an SD card slot and with NAND storage, I should use rkdeveloptool together with u-boot-main.img.xz. I connected the TV box to my PC using a USB-A-to-USB-A cable through the OTG port while holding the reset button. The device appeared as 2207:320b, so I connected it to WSL using usbipd-win. I decompressed u-boot-main.img.xz and flashed it with: bash sudo rkdeveloptool wl 0x4000 u-boot-main.img The command completed successfully and showed: text Write LBA from file (100%) I then wrote the Multitool image to a USB flash drive using Rufus/Win32 Disk Imager. I also tried placing the Armbian image in the images folder. However, after flashing u-boot-main.img, the TV box no longer outputs any video. The TV reports no HDMI signal, and the screen remains completely black. The red and blue LEDs remain on.
