Without a serial console, you can`t do anything about it.

so this is what you have to do:

1 - clean the board with some alcohol
2 - make a good quality photo
3 - upload it here

I wanna see how bad is it and if it can be fixed.

OK, tomorrow I will upload photo

OK, I did a high quality photo of my router, and this is what you have to do:

- Scratch the red points (you need a magnifier)
- Solder 2 wires with a 15W soldering iron...more than that and you will deteriorate the pcb (you need a magnifier)
- Check the wiring to avoid doing any bridges.
- Follow my first post and you will be able to recover your router.

Good luck.

Put my RX is damage ( that you show in your picture ). So this is the end of the router, right ?

no, there are no other pins, they go directly to the CPU!
