- | This router uses k3x builds and not k26 or k24 builds, although supposedly (and this does work, tested 2016-05-08) you must initial flash from stock to dd-wrt with a k26 e1200v2 build, for example this: ftp://ftp.dd-wrt.com/betas/2012/07-20-12-r19519/broadcom_K26/dd-wrt.v24-19519_NEWD-2_K2.6_mini-e1200v2.bin. To find the latest builds, you can browse the DD-WRT file server and look for the broadcom_K3X folder, in there is the appropriate for your unit. | ||

Do NOT flash larger builds!
Flashing Instructions
Support was added in build 18846, so do not use older builds. After the e1200v2 K26 initial flash file, only use K3X nv64k builds to upgrade.
WARNING: don't confuse this with other Linksys E-Series units use nv60k builds, this one uses nv64k builds!
- These instructions were performed with an e1200v2 running FW_E1200_v2.0.07.002_US_20150108.bin
- Download the initial flash trailed build: dd-wrt.v24-19519_NEWD-2_K2.6_mini-e1200v2.bin and Upgrade build dd-wrt.v24-29519_NEWD-2_K3.x_mega-nv64k.bin (or later)
- Log into the Linksys Web Interface Firmware Upgrade page, via an ethernet port.
- Do a reset using the stock web interface. Wait a minute.
- Flash the firmware dd-wrt.v24-19519_NEWD-2_K2.6_mini-e1200v2.bin
- Wait 2 minutes. It will reboot on it's own.
- Wait about another 2 minutes until it finishes booting.
- Log into the dd-wrt web interface and set a password
- Flash dd-wrt.v24-29519_NEWD-2_K3.x_mega-nv64k.bin (select reset to default settings)
- Wait 3-4 minutes for the flash to complete then if isn't accessible, manually power cycle the router
- You are done.
Build 33555 mega runs on this router, while many of the previous 2017 builds are too large to fit the flash. [tmittelstaedt] (10/24/2017)
Build Information
Following the initial flash instructions from stock to dd-wrt with ftp://ftp.dd-wrt.com/betas/2012/07-20-12-r19519/broadcom_K26/dd-wrt.v24-19519_NEWD-2_K2.6_mini-e1200v2.bin, use builds with K3.x and nv64k in the name for upgrading, like ftp://ftp.dd-wrt.com/betas/2016/04-25-2016-r29519/broadcom_K3X/dd-wrt.v24-29519_NEWD-2_K3.x_mega-nv64k.bin. Any other builds for upgrading an existing dd-wrt install without K3X and nv64k in the name will brick your router! Build must be greater than 18946. For the safest results, use builds that are linked within this wiki as they have most likely been forum tested with ok reported results.
More Information
If you use the old Wiki instructions (not here anymore), it will screw up your flash and you will end up with non working Ethernet ports, only WiFi. Reference http://www.dd-wrt.com/phpBB2/viewtopic.php?t=277707
Old Forum thread: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=153176
Recovering from 'Management Recovery Mode', or No Ethernet Ports
In a NUTSHELL, there is a persistent bug in nv64k build of K26 and K3X broadcom firmware, where a reset has the ethernet ports not bound to anything. Using the web interface over wifi, it is possible to add VLAN1 (ethernet ports) back to the bridge, and then they work. See: Linksys_E1500#Recovering_from_Management_Mode_Firmware_Recovery_or_No_ethernet_connection
For issues with Management Recovery Mode, substitute E1200 for E1500, using the appropriate firmwares.
Reverting to Stock Firmware
Download the stock firmware image from the manufacturer's website (link), reset the router back to defaults using a 30-30-30 hard reset, then flash the stock image from within the dd-wrt webgui. After 5 minutes it should finish, you will then need to do another 30-30-30 reset and then access the stock webgui @ 192.168.1.1
