: WZR-600DHP Revert to Buffalo encrypted firmware from community DD-WRT
: gatorparrots January 06, 2017, 12:02:06 PM
I had given up all hope of Buffalo providing an updated firmware for the WZR-600DHP and was sick of getting wifi drops from the last stable version released. So i had moved on to the community build of DD-WRT. But just now, SHOCKINGLY, i saw that Buffalo had released wzr600dhp-pro-v3.0-r30355.enc  based on build r30355. Is there any hope of reverting to the Buffalo supplied encrypted firmware (.enc) from the standard Community DD-WRT? I have not successfully gotten any TFTP procedures to work, from either a Windows XP or OS X machine trying the techniques discussed on DD-WRT's wiki for recovering from a bad flash.

So i'll answer my own question, since there is so much conflicting and misinformation out there.

:
$ tftp 192.168.11.1
tftp> binary
tftp> rexmt 1
tftp> timeout 60
tftp> trace
Packet tracing on.
tftp> put Professional-v24sp2-20180a.enc
Cancel out of the setup wizard for now, but change the default login credentials. Now you can upgrade to the latest Buffalo-supplied wzr600dhp-pro-v3.0-r30355.enc firmware version.

You know the latest firmware gave me a response improvement. I was running Pro-v24sp2 20180b. I was trying to find the latest and your post lead me to that - so thanks. Apparently the "check for updates" in the GUI doesn't work, as it was not showing pro-v3.0

I'm trying the steps gatorparrot has provided -- I just don't seem to have the timing right with my WZR-600DHP.  I've tried both with the dummy MAC (02-aa-bb-cc-dd-20) as well as the device's actual MAC.

From power-on of the router, all the LEDs flash at about 6 seconds in; then it's another 20 seconds or so before the wireless connection LEDs turn on.  The instructions state the connection LEDS should start at about 10seconds.   I've tried starting TFTP at 6 seconds, at 10 seconds, at 25 seconds, etc.  In each case the transmission over TFTP doesn't work (it times out).

Also have tried Pumpkin TFTP, the linksys TFTP.exe and TFTP2.exe programs, all without success.

Just as background for what I'm trying to do: I have Buffalo latest r30355 installed, which doesn't seem to offer a repeater bridge mode (it does not appear in the wireless mode drop-down).  I'm trying to switch to community DD-WRT so I can use this router as a wireless bridge...

I've been at this several hours and can't seem to hit it right.  Any other ideas out there?
Thanks!

There's a community release almost 1500 revisions newer than the buffalo for the V1 WZR-600DHP here: ftp://ftp.dd-wrt.com/betas/2017/04-06-2017-r31825/buffalo_wzr-600dhp/

For the V2 WZR-600DHP it's here: ftp://ftp.dd-wrt.com/betas/2017/04-06-2017-r31825/buffalo_wzr-600dhp2/

I've only used this revision via the 1750DHP on the US, RU and UK/EU routers i own. So can't be 600DHP specific; but the issues with bridges and repeaters seem resolved...

If moving from Buffalo, use the factory-dd-wrt-NEW version
If moving from DD-WRT community the web-flash should be OK (If not try again with the factory-NEW)

Whatever you do select "Reset to Factory Defaults" (Or similar) when updating the router otherwise chaos will ensue (and maybe a bricked router). This is generally good practice when updating anyway; for the sake of some pencil and paper time...

Also consider a 30/30/30 reset before doing ANYTHING with updates; it's not necessary all the time but may eliminate some issues with some versions of the router before doing an update and risking a brick...

So I am running wzr600dhp-pro-v3.0-r30355. This is supposed to be Buffalo's flavor community build right? I would like to move to a later release of the community build. When trying to do the Web Firmware upgrade it says 'update failed'. I'm trying to load http://www.dd-wrt.com/site/support/other-downloads?path=betas%2F2017%2F05-02-2017-r31924%2Fbuffalo_wzr-600dhp%2F?path=betas%2F2017%2F05-02-2017-r31924%2Fbuffalo_wzr-600dhp%2F (http://www.dd-wrt.com/site/support/other-downloads?path=betas%2F2017%2F05-02-2017-r31924%2Fbuffalo_wzr-600dhp%2F?path=betas%2F2017%2F05-02-2017-r31924%2Fbuffalo_wzr-600dhp%2F) buffalo_to_ddwrt_webflash-MULTI.bin.

I read that Buffalo has something in their firmware that prevents loading of other community builds. If that is true, what sell these as DD-WRT compatible routers???

So I then tried the TFTP thing for a couple of hours and nothing. I did both the special Arp MAC and the device MAC. I've tried all the timing and resetting. Nothing. Read the Wiki, forms, tried all posted items - I never see the tftp client take. The router boots into normal mode. I've done power cycles and hard resets. Just nothing.

So why is it so hard to upgrade a DD-WRT compatible router to DD-WRT??
