Flashing

Flashing DD-WRT

NOTE: DON'T BRICK YOUR ROUTER! WHEN YOU'RE FLASHING YOUR ROUTER FOR THE FIRST TIME, USE ONLY THE *-factory.bin files. THEN, NEVER UNPLUG ANY WIRES OR YOU RISK TO BRICK YOUR ROUTER!! THE ONLY CABLES YOU'RE SUPPOSED TO HAVE IS THE POWER CABLE AND THE ETHERNET WIRE GOING TO YOUR COMPUTER. FINALLY, DOWNLOAD THE OPENWRT BINARY WITH THE LINK PROVIDED BELOW AND CHOOSE THE VERSION YOU WANT. MAKE SURE YOU DOWNLOAD THE GOOD ONE FOR THE E1550.

• Supported

1. READ the Broadcom Announcement Carefully! Link
2. Disconnect all cables and wireless clients.
3. Do a 30/30/30 reset on router
4. Connect 1 Lan cable to pc doing the flash.
5. Log into Linksys Web Interface Firmware Upgrade page at 192.168.1.1 and flash the needed firmware.
6. Wait 10 minutes until WLAN (wireless) light turns on.
7. Power cycle by unplugging E1550 for 30 secs.
8. Plug E1550 back in and wait about 5 minutes until it finishes booting.
9. Do a 30/30/30 reset on router.
10. Wait 3 minutes and log into web interface.
11. You are done. There is no NEED to flash any other build.

Upgrading

Updating DD-WRT

If dd-wrt is already on the router follow these instructions. If stock firmware is on the router follow the flashing instructions.

1. Check for recommended builds here first.
2. 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.
3. 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.
4. Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
5. Wait...at least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
6. Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
7. Wait for the lights to return to normal usually about 2 minutes.
8. 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.
9. 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!
