Flashing DD-WRT[edit]

'Flashing DD-WRT

  1. Hard Reset/30-30-30
  2. Configurge PC for a static ip of 192.168.1.10
  3. Make sure nothing else but power and PC is hooked to router
  4. Load dd-wrt.v24-18946_NEWD-2_K2.6_mini-WNR3500v2.chk
  5. Wait 5 Minutes
  6. Browse to 192.168.1.1, make sure you get the change password page
  7. Hard Reset/30-30-30
  8. Browse to 192.168.1.1, change name and password, configure.

Flashing TomatoUSB[edit]

Upgrading[edit]

'Upgrade DD-WRT

===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!

DD-WRT Serial Recovery[edit]

Once you hooked up and getting data in putting/Hyper terminal and have a static ip on you pc of 192.168.1.10,

Power cycle the router. Imediatly start rapid firing CTRL+C until it breaks into the CFE.
  1. Get TFTP ready with the OEM firmware.
  2. Type tftpd, then click upgrade on the TFTP window.
  3. Give it about 5 min to bootup and settle, then goto 192.168.1.1

DD-WRT JTAG Recovery for Universal JTAG Adapter[edit]

Confirmed Working with North American Unit and Firmware

  1. Power Cycle, tjtag3 -backup:cfe128 /silent /otheroptions
  2. Power Cycle, tjtag3 -backup:nvram /silent /otheroptions
  3. Power Cycle, tjtag3 -backup:wholeflash /silent /otheroptions
  4. Power Cycle, tjtag3 -backup:custom /window:0x1fc00000 /start:0x1c3e0000 /length:0x10000 /silent /otheroptions
  5. The last step will backup the board data to "custom.bin, Using a Hex editer, check to make sure all the data looks similar to board_data.bin or post it to your thread in the dd-wrt forums and somebody can check it for you.
  6. If it is similar, change "U12H127T70_NETGEAR" to "U12H127T00_NETGEAR". The mac address starts at Hex address 40 in the middle pane, make sure it's correct. The Serial number starts at Dec address 76 in the right pane, make sure it's correct. The Security Pin starts at Dec address 108 in the right pane, make sure it's correct. The actual board data starts at Dec address 256 in the right pane, make sure it matches board_data.bin. If it looks all messed up then start fresh with board_data.bin and make all the changes ti it. When done "save as" "custom.bin" without the quotes. Makes sure it's in the same folder as TJTAG.
  7. Now do the same with the cfe128, mac sure mac address match(although not as important with the cfe). Check to see if is similar to cfe128.bin. If not or it's just totally messed up use the reference cfe128.bin. Just edit it to match the information from your router.
  8. Power Cycle, tjtag3 -flash:custom /window:0x1fc00000 /start:0x1ffe0000 /length:0x10000 /swap_endian /byte_mode /silent /otheroptions
  9. Power Cycle, tjtag3 -flash:cfe128 /swap_endian /byte_mode /silent /otheroptions
  10. Have TFTP.exe ready in WindowsXP, with WNR3500v2-V1.2.2.28_25.0.85NA.chk from that zip file.

Configure your computer with a static ip address of 192.168.1.10.

Connect the router to the pc via network cable.

Power on the router when it signals a connection click upgrade.

How To Identify Which Model Router You Have[edit]

by benryanau

After spending an hour researching the variants of the Netgear WNR3500 family and their

specs prior to a purchase, I realized this would he handy to post up somewhere.

So, I thought I'd table it up and share it, since there wasn't a concise guide anywhere

on the web already. Hopefully this will help some people out!
