[edit] Opening Your WRT600N V1.1

• Turn it upside down
• Make sure all the feet are facing outwords
• Now with a flat head screwdriver push under the backside. As shown in Image Below. It's going to resist had me all nervous then it makes a loud pop.

• Now the the other side.
• Now just slide the piece you just loosened towards the back of the router and it should come off the rest of the way.

• Flip over and repeat for top.

• Remove front piece by releasing these clamps they are on the top and bottom

• Now flip it over so the bottom is facing up like so and you will find 4 Screws. Take them out

• Now flip it back over and carefully remove the top it may stick due to the heatsink.
• You should be able to see the serial header - I tried to take it from a few angles as it seemed hard to photo because of the glare from other parts
• Location of Header - Image 1

• Location of Header - Image 2

• Pin Layout

• Color Key for above photo

Red	= Router's RX
Yellow	= Router's TX
Grey	= Ground

• Connect these to your 1/8th Jack
• Inside View

• Outside View

• 1/8 Plug Pin Out - If your using the same USB to Serial adapter as me

• Color Key for above photo

Orange	= Computer's TX
Yellow	= Computer's RX
Black	= Ground

• So you want to connect it like so

Router's RX	= Computer's TX
Router's TX	= Computer's RX
Router's Ground	= Computer's Ground

• Or using my colors on this page

Router	= Computer
Red	= Orange
Yellow	= Yellow
Grey	= Black

• Now put it back together or not up to you but with those heat sinks and these tend to get pretty hot at least mine i wouldn't leave it on long without it.
• Open SecureCRT or Hyperterm
  • Configure as follows
    • Baud rate: 115200
    • Data Bits: 8
    • Parity: None
    • Stop Bits: 1
    • Flow Control: XON/XOFF

• Plug it in to your computer connect using which ever program hyperterm or securecrt
• Power up your device and you should see a loading screen within 1 to 2 seconds never takes long for me

• Proof
  • Screen Shot of DD-WRT Loaded Via Serial Using SecureCRT

• • Screen Shot of DD-WRT Loaded Via Serial Using Hyperterm

Sorry for the delay on finishing this I'm running low on cash and got offered some jobs to do and had to take them which just killed my time able to spend on personal projects. I am starting back to work on this as my free time is returning. I'm also working on a new network booting system to easily configure well network installs and boot over network setup's and i have a few other ideas if you check out the main page you will see a few. I also need to update that.
