I have netgear WNDR3700v2, whit V1.0.0.6 version of original netgear firmware.
I try to install dd-wrt for a lot of time, but the router get on briked status.
Any time I unbrick it whit tftp procedure.

I use Netgear gui web interface, section: Maintenance -> Router Upgrade.
I tey to upload many file, like this:

ftp://ftp.dd-wrt.com/betas/2016/04-25-2016-r29519/netgear-wndr3700v2/wndr3700v2-factory.img
and
ftp://ftp.dd-wrt.com/betas/2016/08-12-2016-r30385/netgear-wndr3700v2/wndr3700v2-factory.img

But the result is the same: brick.

What is my mistake?

Have you tried the unbricking as shown at the end of the wiki?

Do you mean you brick your router after you flash it with the factory.img? Is your router the WV version and not NA version? Have you tried using tftp method to flash the factory.img to the router?

The Netgear firmware that you used to unbrick the router, did you download it from Netgear's WV site or NA site and what version is it?'

How about tftp wndr3700v2-factory.img to the router? Have you tried that yet? Although the requirement for Netgear firmware version not later than v1.0.0.12 may not apply to WW version, to be safe, may be you should make sure the Netgear firmware that you used to unbrick the router is not later than v1.0.0.12.

My previous router (NETGEAR N300 with ddwrt) is damaged.
I bought the NETGEAR 3700v2 becouse I would install ddwrt firmware and replicate previous settings.
If I can't install ddwrt, I may keep the original netgear firmware, but there is only one feature that I don't know how to do.
I ask to help me to install ddwrt, or to implement the following feature on the original netgear firmware:

my netgear router is at home, and I configured a DMZ (I have a NAS into the DMZ). I don't want permit access to DMZ from all internet address, but I would restrict acces to DMZ from only my office IP address. In others words, I would restrict acces to my home-NAS from only my office, and would reject the accesses from others IP-addresses.

I can get this feature with ddwrt: I edit directly the iptable to implement it (the web-gui of ddwrt has a form ad-hoc to do it).
How can I do it with original netgear firmware?

Sorry for a late bump, since I have a similar issue as the OP...

so I have not used DD-WRT since WRT54GL, and have been using two WNDR3700v1 (Gateway) and v2 (AP Extender) with netgear firmware.

Recently I decided to venture into third party firmware, and figured I'd give dd-wrt some try, since I really need OpenVPN client to work on the router.

I downgraded the v2 first to the oldest netgear firmware, and installed the dd-wrt for wndr3700v2 I got from here:

http://www.dd-wrt.com/wiki/index.php/Netgear_WNDR3700

But either the NA or worldwide causes the v2 go into reboot loop, and I'd have to use reset/tftp to unbrick. I did the 30/30/30 a few times as well...

I tried it several times with either img files and no go. I didn't try it on the v1 at that time since I didn't want to brick it either.

I then decided to put gargoyle and it worked... so wonder if I have a special v2 device that doesn't work with this particular firmware ?

Thanks for any suggestions.

Try an older build for the WW Initial.
As an Initial Load the Newer versions of DDWRT are sometimes a little to large.

I would go with like a 2014 Version or earlier.

This is the case with many older netgear routers.

The WNDR3800 is similar and needs a smaller initial flash size.
