How I was able to revert was to flash Buffalo's version of dd-wrt and then flash regular buffalo stock firmware over it.... The link i had for Buffalo's version here
is dead now probably because they are trying to limit dd-wrt from their devices. Newer versions of the stock firmware really limit/make it hard to do so.
So I have one of these routers that was given to me in a bricked state. I have already tried to access the router via a USB to TTL serial connector, only to get nothing out of it. The router takes power and all four of the LAN leds as well as the WAN led coes on. No other lights on the router turn on.
Is there anything anyone can show me per-say that could possibly bring this router back from the dead?

It 's impossible, bootloader of your router is dead, so you can only use it as a switch
Is there any consensus on a good stable build for the wzr-1750dhp? I'm currently running DD-WRT v3.0-r28493M std (12/10/15). It has been running like a champ but 10 month old firmware seems a bit dated.
I've tried pouring through the forums here but can't seem to find any real answers.
It will get WiFi signal quality boosted since r30370M -- if my memory is not wrong.
To me the r30700M does not have any unstable issue on this unit with PPPoE, 4 SSID (WiFi 5G *2 , 2.4G * 2), OpenVPN (tap or tun), SSH tunnel, DNS Masquerade, USB2 pen drive (/jffs), QoS enabled. It was just asked that a NVRAM fully clean-up action is required when the FW is upgraded from r2xxxx to r3xxxx.
Hi, Does r30700M already resolved hardware nat routing issue? I am now only use software nat routing with previous kongac "Firmware: DD-WRT v24-sp2 (08/15/14) kongac"
I seem to be looking in the wrong place or maybe its just not possible. I have 1750dhp running smoothly for the last 2 years without issue.
Firmware: DD-WRT v3.0-r29300M kongac (03/27/16)
I know I should be updated to something a bit more recent especially since the recent security issue with routers. Unsure if mine was affected. But is there a place to download the latest Kong F/W for this router? Thanks!

Is this a simple upgrade loading it via the router interface? Or do I need to downgrade, restore etc? I remember this particular buffalo router was a PITA to get to even take dd-wrt in the first place.

Welcome!
Upgrades have been much simpler for me at least through the web interface. Every so often I have had to do it via command line.
As a suggestion only: I personally would reset NVRAM and then upgrade and then reset NVRAM, then go through and manually set everything up again. Reason being that many options and defaults will have changed and it would be a good idea to review them.
Is there anyway to flash the firmware without open the case? I have just flash wrong firmware by using web interface on dd-wrt. (flashed with wzr-hp-g300nh because I have 2 routers...)...
The router wzr-1750dhp is now booting with 2 flashed buffalo logo every 3 seconds.
When pushing AOSS button, I see that the router is having 192.168.11.1 IP address and asking "firmware.ram" (using wireshark). I try using TFTP (Upgrade firmware version 1.25) upload and rename the firmware buffalo-wzr-1750dhp-wrblfash.bin to firmware.ram but it didn't work. I can use that tool with wzr-hp-g300nh but not wzr-1750dhp.
Well, if cfe is still good then you can load fw up.
1. Open web..Fw or factory-ddwrt in hex edit in android or win hex in window or ihex in mac then save at firmware.ram. if you just rename then its fw become firmware.ram.bin (still ext=*.bin).
2. set computer to 192.168.*.* //may be 192.168.11.1 or the last one cfe preset.
3. Open tftp server then set host as 192.168.*.* //*.* is the ipaddr of cfe of router.
4. click and load firmware.ram file.
5.Set default to 128kb //should be minimum
6. Dont forget LAN cable
7.click put //here the GUI interface
note: how to know if router is semi-brick but not complete bricked.
connect LAN cable and restart route's power.
1.LAN from disconnect status to enable //cfe is good
a. LAN from connect status and continue without search ip // router is bricked.
b. LAN from connect status and disconnect then reconnect status//router is normal.

Generally:
Flashing AC1750 firmware on a WZR-1750DHPD locks the device, which makes it difficult to install DD-WRT or OpenWrt afterwards.
Flashing DD-WRT firmware on a WZR-1750DHP voids its warranty.
The CFE does not recognize TRX checksums, which must ignored or forced
It seems the only way to unbrick is open the case to have serial access.
I tried your way but the CFE didn't ACK the TFTP PUT so no file was transferred. I'm sure that I put the correct file name with correct extension. I know how to rename a file with extension
