Hi all, sorry if this is an older unit but I've come into possession of several Netgear EX6200 units and went to put DD-WRT on them but when I try to flash I get an error that there's a problem with the firmware. I'm using the factory to dd firmware, and tried the bin and chk files but no luck. The current firmware on them looks like it's something like 1.X.X.X

If the current stock firmware will not accept the oldest stock firmware, you'll have to use nmrpflash to downgrade it. I would have to look at the latest ambit commits for Netgear to see if flashing any builds from this year would work, but they should. I would likely recommend 46446 as a starting point, then upgrade to 46979, if you wish. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

I was able to install the firmware from the German Netgear site. That worked. However, using the recommended firmware that kernelpanic-69 posted, it fails to update.
OK tried to send the FW via nmrpflash and it fails with this message:
nmrpflash -i net17 -f factory-to-dd-wrt.chk

Looks like a reboot and a reflash and I got DD-WRT going. Thanks all. I think I got this going but I need to set one of the ports to act as a WAN port?

Correct. I am not sure how builds newer that 46446 will act on this device at present as I do not recall anyone reporting on it. I don't have one of these on hand personally to give any further 'educated' guidance on. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"
