No, I got Multitool backup files, dtb, dts, Android Tool Image before bricking when original Android yet was installed. This links are with this files.
Multitool don't work more after bricking. Now here show red led, no more blue led blinking and no image to TV/Monitor (hdmi) when power on tv box using Multitool on SD card.
It must be a few days before I get one. In the meantime, I'm going to look for it and maybe someone got it and posted it somewhere how to force maskroom mode. Thanks.
