Set your computer to a static IP of 192.168.1.7. (or to whatever subnet the router is on) Disable all firewalls and security. Disable wireless on your computer and only have the router connected to the flashing computer by the ethernet cable between the two.
Hard reset or 30/30/30 (If the router supports it, if not, reset to defults in the GUI) prior to flashing. Wait. Check for password page on re-login and change password.
Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
Wait...at least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
Wait for the lights to return to normal usually about 2 minutes.
Hard reset or 30/30/30 again (If the router supports it, if not, reset to defults in the GUI). Wait. Check for the password page and re-login to change the password. Then you can reconfigure your settings manually.
Once configured set your computer back to autoIP and autoDNS.
Important1: This Hard reset or 30/30/30 works fine for Asus router, but you do have to power cycle after the reset.
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 WAN 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!
Set a static IP on your computer to 192.168.1.7. Subnet mask should be 255.255.255.0.
Connect the lan cable from your computer to a LAN port of your router. Make sure your router is plugged in. Nothing should be connected to your computer or the router except the LAN cable between them. Turn your firewall and any wireless computer connections OFF.
Power cycle the router (uplug the power from the router for 30 seconds and then plug it back in)
Open your browser to 192.168.1.1 by putting that in the browser address window of your browser. You should open the linksys webgui and NOT a page that says Management Mode. If you see management mode, power cycle the router again.
Wait for DMZ light to do a steady pulse, When it is lit on the 3rd time click upgrade. The DMZ light must be lit when you click upgrade.

I installed the new version "dd-wrt.v24_mega_generic.bin" over default configuration of the version "dd-wrt.v23_vpn_generic.bin" and I had no problems.

Flashed dd-wrt.v24_mega_generic.bin directly from linksys web interface (version WRT54GSv3_4.71.4.001_fw.bin) without issue. -Sapremias

I installed dd-wrt v24 sp1 Mega Vintage (dd-wrt.v24-9517_VINT_mega) from stock firmware with no issues. Standard process:
1) Reset router - reset for 30 secs w/ power on
2) Upload dd-wrt
3) Reset router - reset for 30 secs w/ power on
4) Disconnect/reconnect or ipconfig /renew

I nearly bricked my router going directly from Linksys firmware to dd-wrt.v24-11296_VINT_STD.bin. Pinged on boot but tftp wouldn't work. Router didn't even respond to JTAG. Shorting pins 5&6 with the router unplugged somehow fixed everything. From there I was able to flash to mini, then back to std.
