Hi, a long time ago I flashed this Chinese router lb-wr3000 with a firmware and it stopped working.

I don't remember the firmware image that I used cause it has been more than a year.

But now I'm trying to unbrick it, I've connected a TTL serial to its 3 pins and got the below message which I can't interact with it.

Can someone please figure out how to unbrick it or even restore the original firmware .

Thanks.

I seem to remember that on some routers RX is disabled - you have short some pins or install some components.
And 16+2MB isn't enough for OpenWrt.

I have seen some TP-Link routers with disabled RX, but this router's RX has a clear path to the main chip.
Well if I managed to figure out how to enable RX, then I will restore it to it's original firmware.

But what about the bootloader, is it the same as TP Link router, meaning can I use same commands that I used before with U-Boot???
