I might be wrong, but if I remember correctly Netgear added this restriction because they started to use a newer flash RAM and the older Netgear versions could not cope with that.
So although you might be able to flash older versions with some trickery it might brick your router.
Not sure if this is true or just FUD from Netgear

DDWRT always could cope with different flash RAM's

You might not need any special tools as BS has modified the header of the factory-to-ddwrt.chk file
(There must be a commit in the repository will see if I can find it later)

So with any luck do the following:
1. Reset router to defaults
2. Upload the factory-to-ddwrt.chk via the GUI, I think version 41328 is worth a try
3. After uploading telnet to your router and do:
Code:
nvram erase && reboot
4. Setup your router

For the R7000 some nice links:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=264152

I have put together a guide for the R6400v2 and although the R7000 is slightly different the general workout is the same so do not follow this guide literally but it will give you some idea.
The guide and als the unbricking guide can be found with the link in my signature (at the bottom of this post)

Just for sake of completeness some forum rules:

1. Read the forum rules: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=54959.

2. Read this: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=54845.

3. Research your router, start with the supported devices wiki:
https://wiki.dd-wrt.com/wiki/index.php/Supported_Devices .

4. In the supported devices wiki you can see what architecture your router has and if you are lucky also an install guide/wiki.

5. Post in the right forum, from the former step you can see if your router is Broadcom, Qualcomm/Atheros, Marvell or other, use that forum to post router specific questions, for Networking questions post in the Advanced Networking forum and for other things in the General Questions forum.

6. When posting always state router model, build number and when applicable the Kernel version.

7. Do NOT use the router database, builds can be found at:
https://dd-wrt.com/support/other-downloads/?path=betas%2F2019%2F

8. Before uploading a new build research the build by looking in the build threads this is an example of a build thread for build 41328 for Broadcom routers:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=321699&highlight=41328
Search build threads with the search function and search on build number.

9. Use the build threads frorm the former step to report success or problems.

If you have experienced the power of DDWRT you will never want to go back to stock but you will have to put in (some )effort to learn its quirks.

Oh and welcome at the forum Smile

EDIT: found the commit: https://svn.dd-wrt.com/changeset/39293


Followed your instructions and everything went great! Thanks again for your help. I'm going to have a blast with this now!

OMG...I am so happy I finally found this! I was going to pick up an R7000, but I couldn't definitively determine if DD-WRT would load until I found this thread.

Would it be possible for someone to update the R7000 wiki page to indicate that the BS builds should now work? I spent a lot of time sifting through pages with (apparently) outdated information and broken links to Kong's site before finally landing on this thread.

I do have the last Kong build, still stable and not that old for my set up.. I can post it to you if so...

Or, you could do this and keep hits up on CloneVince's Kong Broadcom build repo:

http://ddwrt-kong.clonevince.fr/Supported%20Models

http://ddwrt-kong.clonevince.fr/40270/

You know, since CloneVince pretty much stated that if it quit getting hits, he would likely take it down.

So, to do that, would I first flash the dd-wrt.K3_R7000.chk file, and then dd-wrt.v24-K3_AC_ARM_STD.bin? I don't see an R7000-specific bin file, so I'm guessing that the "STD" file is the right one. The only instructions I see are on the R7000 wiki page, and they are a bit vague. I want to make sure I get this right.

Initial flash only requires the .chk. You don't need a .bin file until you upgrade to a newer firmware or downgrade to an older one.
