Mar 06, 2019. My power lapsed during a firmware update on the R6700v2 and now the routher doesn't work. When turned on, the power light is steady amber. I tried a factory reset and 30/30/30 and the router still doesn't work. During and after the 30/30/30 the power light changes to blinking white. After serachin.

This article describes how to do an initial flash or a TFTP recovery flash for your device.
[edit]Special Asus TFTP Flashing Procedures
Some routers like the Asus WL-500xx series (WL-500G, WL-500G Premium, WL-500W, WL-500G Deluxe), need additional steps to perform a complete and proper initial flash. See this wiki page: Asus TFTP Flash
[edit]Special for Vista, Win7 and Win 2008
In order to catch the narrow window for TFTP flash, you should use platforms with simple TCP/IP implementations that don't have CTCP implemented: Windows XP or Linux are reported to work, but some have reported significant problems with Vista, Windows 7 or Windows 2008.
Edit: While some may have reported problems, CTCP is definitely not the issue, because it is disabled by default in Windows Vista and Windows 7. So unless people are specifically turning it on, it isn't running. I personally just used TFTP on my router with no difficulties, although mine is a Netgear WNDR3700 that was waiting for a TFTP flash and didn't have this race condition at boot as some of these routers seem to. But again, even if you have an issue it's not CTCP. Check out the wikipedia article on CTCP for information on how to check if it is running and how to disable it (both are simple command line entries).
If having issues, try connecting a separate network switch between the PC and router, so the PC network port sees a connection before the router port is up. This should allow for a faster ping reply. Then follow the instructions as normal.
[edit]Special for Linksys WRT54GL Users
If the router seems to be bricked so that the power light is constantly blinking and pinging the router results in TLL=100 continuously, then there is still a great chance that tftp can help. Firstly you must flash the router with the original firmware available at Linksys homepage www.linksys.com, since flashing it with DD-WRT probably won't give any result at all. Then do a 30/30/30 and after that you can flash with DD-WRT Mini. The initial flashing can be done with only the mini version, perhaps later you can move on to bigger versions of it.
[edit]TFTP Tools![]()
With TFTP, all of the information about the transfer is specified during the initial command/setup; there is very little client/server interaction compared with standard FTP.

This example is after a bricked update, using a Belkin f5d130uk (which has a bootloader built in, no need for redboot)
and see if it is responding, e.g. like this
.. you will have to start the tftp upload in binary mode immediately after the first pings responses. The TTL of the boot tftp server will be 100 or 128. It usually does 5 pings responses, after that it will boot the firmware in flash, this is the right time to flash (the TTL of DD-WRT is only 64). If the upload doesn't work the first time, then you have to try the first steps again. you have to be very fast! ;-) Maybe you will have to reset the device via reset button a few times to get the tftp boot working (Siemens, Belkin and similar hardware).
