In both cases from above you can get a copy of the nvram if you da a "save settings" and name it nvram.bin | In both cases from above you can get a copy of the nvram if you da a "save settings" and name it nvram.bin |

Thanks to Eko
As there where always the same questions, i decided to start a page who tells in general how you can get your Broadcom based device running DD-WRT.
Compatibility
There are a few things to be figured out before we start. We/you need to know if its possible to run DD-WRT on it!
- check the Supported Devices page if your device isnt supported already!
Please do the following check list and if one point fails your device will be not able to run DD-WRT!
- check the Known incompatible devices page and read it carefully. if you device is listed or fits into the incompatibilty information...you´re out of here
- open the device and check if it´s Broadcom based (cpu) or is there the FCC-ID printed on a label? check on FCC.gov with the FCC-ID if your device is Broadcom based (internal pics)
- open the device find the flash chip. check out the chip @ Datasheet Catalog and if its <2MB, you´re out.
How to start?
Now that we know that the device is able to run DD-WRT you should do this:
check with a forum search if the device isnt already requested!
if not, start a new topic @ the forum with the subject: "your device with revision" give us all info we need for starting
- FCC-ID
- internal high res pics of CPU, RAM, FLASH, PCB
- maybe RAM/FLASH size and type and CPU type if already known
and if possible
- cfe.bin & nvram.bin via JTAG-Adapter (CFE_backup#by_JTAG)
- serial output
if you have already running a 3rd party firmware (dd-wrt, svesoft, openwrt,...) you can try this to get the cfe: CFE_backup#by_telnet.2FSSH
only if you are instructed to flash a special dd-wrt version for inital flash and it will not brick your router plz give us cfe which is quiet easy as you see here: CFE backup
In both cases from above you can get a copy of the nvram if you da a "save settings" and name it nvram.bin
We finally installed DD-WRT but no reset button/led working
This page describes how to detect the correct GPIO´s for LED and rest button when you have a device which is WIP for running DD-WRT.
Detecting reset Button
1. telnet in and then...
try to find gpio for the reset button.
gpio poll number from 0 to 8. e.g. Code:
gpio poll 4
Then press the reset button in and out and look for changing numbers and report us like this.
gpio 4: pressed = 00 unpressed = 01
Plz only report the gpio that changes. :-)
Detecting LED´s
1. telnet in and then...
try to find for the LED´s
gpio enable number , gpio disable number
e.g. Code:
gpio enable 1
or
Code:
gpio disable 1
go from 0 to 8
If the router stops responding, just power cycle it.
List your findings at the post/to the person who asked for it!
