I found this download link: https://mega.nz/file/f1okwZjB#7VrJQQRP9QLEJsT1MazpQO0rQAxSssnajUp4uhvpF4Y in the description of this video https://www.youtube.com/watch?v=9bW9fGokyLE I flashed this to my TV box and succesfully installed armbian on the eMMC afterwards

I was trying to flash the eMMC of my X88 PRO 10, which bricked it. I need some help to unbrick it. So far, I have managed to put it into maskrom mode by conneting the two contact pads in the red circles and pluging in a USB A to A cable in the USB 2.0 port of the tv box and my computer. I took a backup of the firmware with the multitool from here: https://forum.armbian.com/topic/17597-csc-armbian-for-rk3318rk3328-tv-box-boards/page/1 but I could not find a way to restore it. I tried Android tool reports, which says "Found One MASKROM Device", but threw an error when I tried to load my backup. So I searched for the origional firmware, but could not find a source that was working. Can someone help me unbricking my TV box?
