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 K2.6 for DD-WRT, Do not flash anything else!

Support started version: K26 build 14567
Current supported version: ?

The work is definitely in progress as of June 2010 (read thread first): http://www.dd-wrt.com/phpBB2/viewtopic.php?t=73601&postdays=0&postorder=asc&start=0

As of July 2010 you can only use the trailed builds with the e3000 name in it for initial flashing and nothing else, using other bin's without the e3000 name in it for initial flashing may result in a bricked unit! After you have dd-wrt installed to your unit, you can then use the e2k-e3k.bin's for upgrading to newer builds. This is a common error which is leading to many bricks in which serial is the only method for recovery, so read carefully!

Use only e3000 specific firmware (with e3000) in the name, minimum 14584 Eko build. For example dd-wrt.v24-14584_NEWD-2_K2.6_big-e3000.bin
Flash straight to the big build using Cisco-Linksys web interface.
After successful upgrade message comes up, give it extra 2-3 minutes to complete flashing.
You may need to clear your browser cache after flashing to see dd-wrt's web interface
Some people have been having heat issues. Razing the router off the ground helped.
It has been reported that you can revert to the original firmware by simple upgrading through the GUI, source http://www.dd-wrt.com/phpBB2/viewtopic.php?t=74703

Disconnect all cables and wireless clients.
Do a 30/30/30 reset on router.
Connect 1 Lan cable to pc doing the flash.
Log into Web Interface and flash the firmware ftp://ftp.dd-wrt.com/others/eko/V24-K26/svn14853/dd-wrt.v24-14853_NEWD-2_K2.6_big-e3000.bin
Wait 5 minutes until WAN light turns on.
Power cycle by unplugging E3000 for 30 secs.
Plug E3000 back in and wait about 5 minutes until it finishes booting.
Do a 30/30/30 reset on router.
Wait 3 minutes and log into web interface.

You may have to clear your browser cache before the web login will display.

DD-WRT E3000 Build information

The latest builds for this unit can be currently found in the FTP. Support was added in 14826 and on.

ftp://ftp.dd-wrt.com/others/eko/V24-K26/

Brainslayer added E3000 Support from 14929 and on and builds are to be found in the broadcom_K26 folder of his build branch.

ftp://ftp.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/

Also it has been asked about the builds with e2k-e3k name in them, these builds are for if you already have those units flashed with dd-wrt, you can simply use one of those builds to upgrade, but the initial flash should always be done with the trailed build (build with the unit only name in it) linked above.

Flashing OpenWrt

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.

DO NOT BUY DEVICES WITH 8MB FLASH / 64MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 8/64 warning for details.

This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.

This means that you will not be able to install many packages, and that you might experience crashes due to OOM situations more or less often. See OpenWrt on 8/64 devices what you can do now.

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.

Upgrading

If dd-wrt is already on the router any build with nv60k in the name can be used.

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!

Reverting

Reverting dd-wrt

To revert back to stock firmware from dd-wrt do the following.

Go to Linksys support site and download the latest stock E2000 firmware image.
From within the dd-wrt webgui go to Administration > Factory Defaults, and reset to factory defaults.
Once you router has reset to factory defaults, set a static ip on your machine to 192.168.1.6 and access the webgui @ http://192.168.1.1
It should prompt you to set a user/password, do so, then from the webgui, go to Administration > Firmware Upgrade
Select to reset to defaults on the drop down menu and then browse to the stock firmware image for the E2000, select the file and flash.
Wait 5 mins from flashing, then do a 30-30-30 reset and login again @ http://192.168.1.1 and begin your config on stock firmware.

Should you want to use DHCP you will need to then unset your static ip on your machine.

Serial Recovery

Unbrick hard bricked (no ping) Linksys E3000 via serial connection.

I accidentally flashed the wrong dd-wrt firmware on my Linksys E3000.
This prevented me from recovering with any firmware. I was unable to reset the router, ping the default address, or communicate with it in any way.
To recover I had to initiate a serial connection.

This router, along with others has serial contacts inside, on the bottom of the WAN port.
I tried to make a cable out of a 40 PIN IDE cable that would touch these contacts, but got tired of fiddling with it. Instead I opted to solder directly to the board.

The first step in this process was to open the router. This requires a TORX T-10 Security screwdriver bit. I was able to purchase this for about $8 at my local lowes. It’s the TORX bit with a hole in the center.

Next, I had to pull the plastic chassis off, which was quite difficult. I found it easiest to seperate the pieces from the front.

After the casing was removed, I had to unclip the three antenna wires, and flip the board around. The serial contacts are located on the underside.

[1]

After locating the contacts for the serial port, I had to identify which of them needed to be used.
My Serial->USB adapter was a CA-42 Nokia cable that I bought off ebay. There were 3 wires in the cable. Blue (GND), Green (RXD), and White (TXD).

These three wires had to be attached to contacts 5 (GND), 3 (TXD), and 2 (RXD).
Note it’s important that the RXD wire must be attached to the TXD contact, and TXD on the wire to the RXD contact.

[2]

Once these wires have been soldered to the appropriate contacts, the serial connection should work.
Connect to it from a terminal using 115200 baud, 8N1 with No Flow Control (hardware or software) and ANSI emulation. I use linux, so I used minicom as a terminal, but you could also use hyperterminal in windows.

Now, plug in the USB end of the cable to your computer, and plug in, and power on the router.
You should see activity in the terminal as the router powers up.

[3]

Once you’ve verified that there’s activity, turn off the router and turn it back on. Quickly begin hitting CTRL-C in the terminal until you reach the CFE> prompt.

Once you’ve reached the CFE> prompt the router should be up with networking. At this point you should be plug an ethernet cable into the router and ping 192.168.1.1

[4]

First, clear the nvram by typing:

1	CFE> nvram erase

Once that has completed, you can begin to send the ORIGINAL linksys firmware to the device.

Using another terminal (or command prompt) prepare the TFTP command to put the firmware on the device.
In linux, I connected to tftp 192.168.1.1, then set the mode to binary, set the timeout to 90 seconds, and entered:

1	CFE> put <filename>

.
Don’t execute the put yet, just get it ready.

Back at the CFE> prompt, type:

1	CFE> flash -ctheader : flash1.trx

As soon as you execute the flash command, execute the tftp command. This will upload the firmware.

After the firmware is copied to the router, in the CFE prompt, type:

CFE> go

The router will reboot and load it’s new firmware.

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.
