Don't know that with it have done, reset button was broken (has repaired), was not ping, power blinked, closing pin flash did not help. After Jtag ping appeared, but not more. Has repeated operation with /noemw /noreset, ok.
However I think that too early on/off after uploading Linksys firmware...
If you want to upload Linksys firmware via JTAG, you need to take off the header with a hex editor. However, you can upload dd-wrt generic images in their current form.
Alternatively, you could erase the kernel and nvram and use TFTP to flash the Linksys firmware. _________________ WRT54G v3 - v24 r14471M NEWD Eko - AP

You will need a CFE.bin file for a wnr834b v.2. Not sure whether someone around here has one. Good luck.

It is a 54g-TM I used the new method and bricked the 1st one I did,by setting the network adapter to 1.1 instead of 1.2 in the advance settings.Others have worked correctly.The bricked one above has nvram and kernel all 00's.(erased)

You don't really need to flash nvram, erase it, and let the system rebuild it for you. Do you have firmware on the router also ?
If nvram is not on the router, the CFE will rebuild it, or create another copy of it, the same goes for the DD-WRT firmware, restore defaults _________________ Want JTAG support - Donate a router

How do you know the nvram and kernel are all 00's, jtag backup ? If you can back it up with jtag, the easy way for me to tell what is going on, is if you send me a backup of your CFE ?
please my frinds i want to cfe.bin for paradyne 6211-i2 proc broadcom 6338 flash mx29lv320b

I have tried everything to debrick my router. Every time I tried to flash cfe using -flash:cfe /noreset it stops at ifc02000 when I try and do a wholeflash it stops at the same address I can backup and erase the cfe but cannot flash past this point. I have tried various cfe including using skynets bootloader. Any suggestions.
I have tried a few things since this post I have replaced the missing resistors at jtag port I have tried tjtag as well as tjtagv2, below is the probe results
