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!

On the DDWRT Wiki
Support started version: v24 06/16
Current supported version: ?

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

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram. DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details.

This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation. This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

OpenWrt support for this device has ended in 2022.
19.07.10 was the last official build for 4/32 devices.

Devices with Broadcom WiFi chipsets have limited OpenWrt supportability (due to limited FLOSS driver availability for Broadcom chips). Consider this when choosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See Broadcom WiFi for details.

Flashing Gargoyle

Initial Flash

???

From DD-WRT

DoesItMatter Wrote:

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!

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, samba, dlna, raid support is included in most the newer builds of dd-wrt. Check the features chart to be sure.
