my WRT54GX version 2.0 router is bricked during the firmware upgrade and the file was (WRT54GX_V2_EU_2.00.20.bix) from the linksys support main site. The power LED is blinking and the DMZ LED is off. I can not access to WEB GUI anymore and after many times reseting also pinging the router IP 192.168.1.1 there is no respond from the router. No respond with tftp too. Anyone can help to flash this router by JTAG or...?

WRT54GX v2

Bootloader: ROME
CPU: Realtek 8651B
CPU Speed: 200 Mhz
Flash size: 8 MB
RAM: 32 MB
Wireless: Airgo mini-PCI
Serial: yes
JTAG: ?

Looks like the V2 has Realtek CPU from that wiki page.

JTAG only supports Broadcom & Atheros, so you may be out of luck with it.

What is the main reason that JTAG dosent support REALTEK 8651B ?! There is a JTAG port on the WRT54GX and also a serial port(UART). I have two question:

1- If WRT54GX has a JTAG port so why it can not communicate with REALTEK 8651B ? The JTAG program dosent detect the REALTEK cpu or the cpu still has unknown pins(TDI-TDO-TMS-TCK) for jtaging ???

2- Is it possible to JTAG the WRT54GX by removing its flash memory from the router and put it to another router's flash memory for example DSL-G624T with AR7 Texas Instrument cpu or WRT54G or WRT54GS with Broadcom cpu ?
