wzr-600dhp2 is also Broadcom (BCM47081A0) based, although wzr-600dhp is Atheros (AR7161) based.
There is one post about wzr-600dhp2 that is in Atheros forum. Can you also move that post to Broadcom forum?
lmkaslash, is your unit still okay? Even after reboots? If you haven't rebooted, can you try rebooting it a few times and getting back to us? My unit always broke on reboot (not sure if this is indicative for everyone).
And if your unit really is okay, it's highly interesting that the Japanese model is okay but it seems like the others aren't. However, flashing 22118 before flashing 22700 is really scary for me, considering all of the problems that I had with 22118 and its instability.
On the USA version of the router, attempting to download the firmware via router doesn't work. I think I know the page you are talking about, it has manuals, software, firmware, etc. But firmware has no entries, so we cannot get it that way.
Also, you guys mention Japanese firmware version 2.00. I believe the earliest American version is 2.03, then 2.07, 2.08 (rescinded by Buffalo because it caused many problems), and 2.09.
I tried to find an English version of 2.03 but failed; I think I found a Japanese version of 2.03, but cannot install on my router -- it's detected as an invalid firmware. I tried to "reverse bufpy" (ubootenv set region JP) but that doesn't work. I don't even know if that's a legitimate region code, however, as it was just a guess.
I downgraded my router from 2.09 to 2.07 and tried to install dd-wrt webflash.bin and factory-to-ddwrt.bin 22770 and they both failed.
So... it looks like only Japanese router owners have luck... unless someone can find an American version of 2.03 to test with.
