Last i knew, jtag isn't supported with the E3000, if you didn't mess up the CFE, you could recover using a serial ttl connection to the unit.

Thanks for your response I'm interested by this method but I don't want risk
because I don't know if the CFE is damaged or not, I have warranty I'll use it in first
if you have more suggestions for recovery the flash please tell me.

My problem is a brick after Hard Reset:

"dd-wrt.v24-15962_NEWD-2_K2.6_mega-e2k-e3k"

(I've already made other updates before without problems following this tutorial carefully:
http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486)

I used the update during 30 mins (with somes problems) but after making a hard reset the router doesn't start and the power led flashing.

I think I didn't wait enough time after the flash because the wireless led has flashing when I restarted it

Quote:
d. Wait...at least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.

Important2: After you flash the firmware, and before you do the hard reset, the router will be building some nvram settings. YOU MUST WAIT FOR THIS TO FINISH PRIOR TO DOING ANYTHING WITH THE ROUTER INCLUDING A HARD RESET. Usually, you can tell when this process is completed by the WLAN light coming on, but it does take several minutes. Go have a beer. There are starting to be more and more people who BRICK their routers by not waiting until the nvram is rebuilt, PRIOR to doing a hard reset. YOU NEED TO WAIT!


I have nothing with ping and nothing when I connect the ethernet

there is no operational jtag on that router. However, serial will fix it.
