Assuming the factory alignment is the same for v1.0 and v1.1, the size limit is 0x7F0000-0x40000 = 8060928 bytes (7872 KB).

Flashing

Important: Read the DD-WRT Firmware FAQ and Peacock announcement first!

Reset

As always make sure to do a proper hard reset before and after updating the firmware. This is not an optional step! Do not restore backups from a different build number or type.

Flashing DD-WRT

For initial flash, a trailed build is required which has header information required by the Linksys firmware.

  1. Reset to factory defaults
  2. Flash it via the stock web interface
  3. Reset again after flashing

For upgrades, use any /broadcom folder non-micro build under 7872 KB (see Where do I download firmware?)

  • Starting with 41351, the broadcom_K3X_mipsel32r1 build can be used on this device
  • Resets are unnecessary, but reset and manually set up before reporting issues
  • Research new build and router-specific threads before trying newer builds.
  • If you have an issue, try clearing the web browser cache or try a different browser.

Reverting to Stock Firmware

Simply reset and flash the stock image via TFTP or through the web interface. Make sure to reset after flashing.

Known Bugs

Initial Flash May Not Work / TFTP problems

Some users may experience "Failed to Upgrade Firmware" messages when upgrading via Linksys web interface, even when using special 600N-specific builds. Also, TFTP will not work after the router has booted, and must be initiated within 1-4 seconds after power-on.
