DO NOT 30-30-30 or erase nvram newer routers! It can brick them.

EA6700: Build 27745 (nvram below 32K, ipv6 - HE 6in4)
E4200: Build 26587
WRT54GL: Retired - waiting in the closet for an emergency.

As always, start with reading the peacock announcement, particularly note 6.

Which firmware did you try to tftp?
It has to be linksys firmware.

And what were your ping responses. You need to provide much more info before you jump into a cable solution. Read note 6 carefully.

What i try:
1. Set static IP 192.168.1.5 Mask: 255.255.255.0
2. i prepare tftp upload stock linksys firmware - (FW_EA6200_1.1.41.164830_prod.img)
3. Run cmd and ping 192.168.1.1 -t
4. when pings get answer from 192.168.1.1 i immediatly press Upgrade in TFTP (i also try some times little before respond)

I get info from TFTP:

Erasing Flash...
Unable to get responses from the server.
Retry (3/3)...

what are the TTL responses? "100" that is the best time to start TFTP

timing can be tricky (very tricky), if you are doing it all right it may take multiple attempts to get the timing just right.

No i trying tftp2.exe with LAN cable

and with serial i have also problem ... because

Serial pins:

nr1 GND
nr2 1.1-2.0 mV
nr3 3,3V
nr4 3,3V

If you have a ttl of 100, then the router is not dead.

Try this tftp utility:
