How can I unbrick Vasteyu Amlogic S912 64bit Octa-core TV Box Android 7.1? Any Firmware?

[MacGyver]

Hi, it looks like there is no firmware available for this device https://www.amazon.com/Amlogic-Octa-core-Vasteyu-Streaming-Dual-Band/dp/B073SVNNJ6 . Mine got bricked after a month which I find ridiculous. I wonder if I could use the firmware of the "R-TV BOX Pro"(https://www.geekbuying.com/item/R-TV...er-380732.html). I created a bootable SD disk with the firmware of the R-TV BOX by following that how-to https://www.cnx-software.com/2016/11...ogic-tv-boxes/

Is it worth a try? I am desperate. I mean it's bricked, it can't get worse anyway, right? Or any idea how to get firmware or custom firmware like from TWRP?

Thanks.

Hi there, I found a link to the firmware. A seller posted it on GearBest but it's hosted on Baidu and Geo-Blocked. You need a Chinese Proxy or VPN. However, it's painfully slow.
Here's the link: https://pan.baidu.com/s/1Sf7afz0cQKDs9KMx6dt3rg
