Replace remote for Android IPTV box

I have a Android TV box which I purchased from Bol Tv service few years ago and right now the remote is not working anymore. I cannot tell the model of this box because it does not show anywhere. I just have a SN which does not provide any info when I search online.

I bought a generic android box remote control from Amazon as a replacement, but it is also not working. I can see the light blinking on the new remote but not doing anything else. It didn't come with any instructions. I am using a wireless mouse for the STB Emu app and it is highly annoying.

Does anyone know if I need to program the new remote in a certain way to make it work? Or a generic remote control to work for this box? Thanks.
