After installing the dd-wrt mini firmware got a brick. Lights amber, no ping, says that cable is not connected, all the ports do not answer(tried other cables). Booting stops, but the tftp runs through the console or by short pins(flashing green).
Is there a way to load the firmware without a network cable?
Sorry for bad english.
The console responds this:

There is a good guide on how to restore a JTAG?
Hope this link may help you regarding your jtag quaries.
why you want to restore with a JTAG? Have you tried reset to defaults to recover your router or some other methods ??
All Other methods are not suitableall and ends that I need a network connection to flash. But as I said before, the network is not initialized, probably corrupted bootloader(CFE).
again, sorry for bad english
Do the following steps,
1. Give a static ip to your PC (192.168.1.X)
2. Connect your PC to Router LAN port.
3. ping to 192.168.1.1
Are you getting some response ??
If yes, then hopefully your bootloader is not corrupted.
Of course not. The network(network cable is not plugged, says to me the operating system) does not work on the router, if it worked, I would have flashed through tftp. Hardware fault should not be, it happened immediately after unsuccessful flash firmware dd-vrt. I've tried to explain earlier. I also found it strange that line:
CPU type 0x19740: 133mhz
But I have already collected jtag cable, and now try to fill through it cfe and firmware.
What is the status of your router currently ??
Have you performed the jtag operation ??
I could not get data from the microprocessor. Probably not right soldered. Since it is not found for NETGEAR WNR3500L scheme, made a connection with this scheme http://www.myopenrouter.com/article/10935/Creating-a-JTAG-Cable-For-WGR6...
If i can not find JTAG pinouts scheme, he will seek, through the datasheet.
The problem finally solved, did not have to JTAG. Finished from the CFE loader "nvram erase" and reboot, then flashed the firmware, all got. It turned easily.
Good to know that things are working at your end. Which firmware have you used to upgrade with??
ORIGINAL v54 >> DD-WRT "Mini" BETA svn 14826 >> 1.9.2.7-rtn-r4330(wl500g Oleg's Firmware)
Brick occurred on DD-WRT. But after a "nvram erase" everything works. USB-TTL cable is useful.
