Flashing
NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power. |
Flashing DD-WRT
WARNING: Do not flash micro this unit! |
WARNING: Requires K2.4 for DD-WRT, Do not flash anything else! |
First, before you do anything else, check which version of the WRT350N you have.
- If you have V1, you're in business. If you have V2, you're outta luck.
Flashing a virgin WRT350N with the default Linksys firmware will require a special "trailed" mini-build to be flashed first.
- You should use a build from the BS Broadcom folder 12874 for the initial flash.
- The name of this file specifically is "dd-wrt.v24_mini_wrt350n.bin".
- You may proceed to flash it with a generic build next, such as Mega.bin.
Remember to do the 30/30/30 Hard Reset after every successful flash.
- It is absolutely essential.
The proper process for flashing is:
- Read Note 1 of the peacock announcement http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486
- Read Note 3 of the peacock announcement
- Download dd-wrt.v24_mini_wrt350n.bin
- Do a Hard reset or 30/30/30 on your router. You will not get a password renewal page as you have stock linksys firmware on the router still.
- Plug a cable into the lan port of the router and your computer, and disable any wireless to the computer. Disable all firewalls and virus protection. (Setting your computer to a static IP should not be required)
- Set your browser to 192.168.1.1. This will open up the linksys webgui
- Enter the username admin and password admin
- Go to the administration tab. Click on firmware upgrade.
- BROWSE to the dd-wrt.v24_mini_wrt350n.bin file you downloaded.
- Click on the upgrade button and WAIT for the upgrade successful message. Wait at LEAST 5 minutes
- Power cycle your router. (very important) WAIT until you can relogin at 192.168.1.1
- Do another PROPER Hard reset or 30/30/30 on your router (very important) WAIT until you can login at 192.168.1.1
- Click on any tab. Reset your username/password by TYPING in a new username/password
- Configure your router
You can now upgrade to any generic dd-wrt build except Micro. Be sure to always do a hard reset prior to flashing another build, do a power cycle followed by another hard reset after flashing, and NEVER re-use a configuration file from a previous build or another router. Reconfigure from scratch.
Flashing OpenWrt
Flashing Gargoyle
From DD-WRT
gargoyle_1.3.13-wrt350n_v1-squashfs.bin
Grab that image from the download section
Linksys WRT350N
Chipset Broadcom 4785
RAM 32 MB FLASH 8 MB
Broadcom chipsets are fairly easy to back-forth between
Gargoyle and DD-WRT
Best recommendation for steps:
- download a backup current DD-WRT build you are using
- backup your current DD-WRT config
- reset dd-wrt to defaults
- from dd-wrt GUI - flash the gargoyle.bin image
- once you start the flash - wait about 5 minutes
- try to login to 192.168.1.1 - defaull password = password
If you want to go back to dd-wrt
- backup your current Gargoyle config
- reset Gargoyle to defaults
- flash the dd-wrt .bin file that you originally saved above
- once again - wait about 5 minutes for flash
- reload your backup config file for dd-wrt
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.
- Check for recommended builds here first.
- 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!

DD-WRT Serial Recovery
Modified redhawk0 instructions
- Print out these instructions for Off-Line use
- Connect PC to router with a network cable
- Configure PC with a static IP of 192.168.1.10
- Connect Serial cable
- Start one of the programs from above
- Get TFTP ready with file selected
- Use dd-wrt.v24 mini wrt350n.bin
- Connect power to the router
- start a rapid fire Cntl-C as you plug the router to power
- type "nvram erase" w/o quotes, hit enter
- type "flash -noheader : flash1.trx" w/o quotes, this starts the tftp daemon, hit enter
- but have TFTP ready
- Click go or start on TFTP
- give it 5 minutes after it finishes
- then power cycle....Hard reset or 30/30/30...then config
- when it stops spitting out txt....hit the enter key...you should get a login prompt...at that point, power cycle it, hard reset...then config
- you'll see it boot up
USB Info
DD-WRT USB
- The USB port is where you can connect an external USB hard drive or flash drive.
- Which can do a multitude of things. You can use in as a NAS, storage for a FTP
- server, use Optware to run external programs like torrent software, samba for
- sharing files to network, share a USB printer with network...
- The list of possibilities is long, it just takes a little research.
- ProFTPd is included in most the newer builds of dd-wrt.
- Check the features chart to be sure.

DD-WRT vlan Info
I can confirm the WRT350N v1.0 does support port-based vlan's via nvram only, the gui doesn't work. "proc/switch" is not present.
