One wire is ground. Measure continuity with a multimeter to the usb connector.

Then connect the other two wires to RX and Tx. Turn on the router. If not appears in the terminal, turn of the router, change places between TX and RX, then turn on the router again.

I connected cable and see U-UBOOT. I saw it and that is a picture form it. When I hit 2 it continue with 3, but may be I have got cold solder I will thy again tomorrow and will write result. This is text form U-Boot with wrong firmware. Is it normal.

It shows the wrong thing, because the firmware is wrong. But the start is correct. You need to start pressing the keys repeatedly right after connecting the router to power.

My friend is going to soldering wires.(May be I am going to try in monday)better and try to flash with wrong firmware. Am I upload again wrong firmware ( I will not do it ) may after that repair with kapastratos' procedure ? If I use only option 2 is there any chance to brick U-BOOT ?

Is this the right configuration on putty ? ( see flow control )

What is the way to brick U-BOOT ( I will not do it )
Is there any chance to have bad sectors like kapastratos ?

Flow control may depend of your hardware. Try with None, Xon/Xoff and Hardware.

smart use of duct tape. All that is needed is a good electrical contact, so you can be creative.
A skilled person could put nails in a piece of wood, in the right places, and tie the wires to them. Or something like that.
