I have an old MXQ Pro 4K (based on the original S905, not S905X or S905D, the original S905) which I tried to install armbian on, but I didn't know extra things were needed to set up uboot and dtb correctly, so I just flashed the image, put the SD card in my box, ran `reboot update` from Android to boot to the SD card, it showed the MXQ Pro logo, rebooted, went back to the MXQ Pro logo, and I can't get it to go past that. My box has a weird firmware issue (started immediately after a firmware restore so I don't think it's hardware damage) where the button in the headphone jack just... doesn't work, even when holding it, it still tries to boot to the eMMC, and now I have no way of getting back into Android, and I can't boot from the SD card due to the button not working, so, is there any hope for my box here? Or have I effectively hard bricked it?
I don't have a USB-A to USB-A cable for USB burning tool, and I will not be purchasing one, this was a spare box I've had laying around for eons and I don't think it's worth spending any money on -- I could probably get a much better box for the same money.
