What model is it

[Xperimental-lain]

I tried to flash OPENWRT Using UART it didn't work and the router got completely bricked .
.Tried one more on my 2nd router and now it's also Bricked.

Its true that Openwrt is available for mt7986 but J used there custom storage layout (FIT) BUT we can compile our own openwrt.
But the actual Main issue is that j has enabled secure boot
