Finally unbricked my WRT54G-TM.Probably took the long way around but got it back to stock firmware.
Took another TM and soldered on a header.Used tjtag and read/saved stock cfe,nvram and kernel.Flashed these to the bricked router.Reset router from the back.Logged into router and used clone function to set mac to orginal.
I still have a bricked wrt54glv1.1 I have erased the wholeflash, flashed the cfe from skynets backed up the cfe and compared the 2 cfe files and they match. The router has a flashing power light and the lan leds are on. I cannot ping the router in fact even plugging into the lan ports shows no leds on the switch indicating that the lan side of the router is dead. I have tried a wholeflash by downloading the dd-wrt.v24_micro_generic.bin changing the name to wholeflash and flashing it still does not work. What can I now try?

No...you need to make the micro_generic.bin file the kernel.bin file...not wholeflash.
wholeflash always overwrites (or erases) the CFE part.
So now....do an -erase:wholeflash twice then reflash your cfe...then load the micro_generic.bin as the kernel.bin.

@Tornado
I can not erase two first blocks in flash and I can not flash in this block with key /noerase ...
My flash chip is marked as Spansion S29GL032A, (http://www.spansion.com/datasheets/s29gl-a_00_a12_e.pdf ).
Please, add this chip in next version of tjtagv2.

All 4 LAN leds on my F5D7231-4 is red,WAN led red/green by chance.No flashing leds
The JTAG cable i use
J12 1 to J1 1 using 100 ohm (a pair of 200 ohm).
J12 3 to LTP 2 using 100 ohm (a pair of 200 ohm).
J12 5 to LTP 13 using 100 ohm (a pair of 200 ohm).
J12 7 to LTP 4 using 100 ohm (a pair of 200 ohm).
J12 9 to LTP 3 using 100 ohm (a pair of 200 ohm).
J12 10 to LTP 20 and 25 (also tried connecting to ground of LTP).
Cable length is about 60cm (~33inch) I used patch cable.
R278,377,376,375,374 should be open!
So what's the deal with mine? Should i somehow short the memory so it's erased and i can connect with jtag or lan????
