I started by doing a 30/30/30 reset and attempted to do a GUI upload of build 40559 to my Netgear r7800. It appears that the upload failed as the router now does a 15 sec reboot time and the power button is solid red.

I have been able to ping it and get an intermittent TTL=128 reply, and the port LED that I am plugged into does blink at the same time, for about 3-5 seconds, then restarts again. I have tried pushing both DD-WRT build 40559, as well as factory firmware v1.0.2.63beta to no avail. I haven't been able to find any firmware for this machine that isn't 20+ MB in size, and a tftp recommends a 2- MB to get it functional and then do GUI for the full version.

Does anyone have any ideas, as I am currently stuck.

well...if you did 30/30/30 on this router it will get to recovery mode and than you did a bad flash i guess...
As 30/30/30 is very very bad idea on this router as on many others too...its bricked now i guess or stuck in
recovery mode...

look here https://kb.netgear.com/000059633/How-to-upload-firmware-to-a-NETGEAR-router-using-TFTP-client

R7800 user manual says to press and hold the reset button for at least a full 7 seconds, that's it.

Wiki and router database strikes again (sorry).

Unplug it. Hold the reset button in and plug it back in. When the power led starts flashing use tftpd32 to upload the firmware.

if you disable the dd-wrt nvram reset thingie you will have to flash the default firmware or openwrt to reset it. These don't have nvram and thus will erase it.

tftp -i 192.168.1.1 PUT file

This is the command to run if you use the reset button until the unit starts having the white flashing light. The TFTP will only accept the builds which are designed to mimic the original firmware. AKA factory to X.

It seems to be extremely hard to brick these routers so just flash back the original firmware then upgrade back to dd-wrt.

In the sticky threads there are some rules explained but the 4 most important are (in random order):
1. When posting always state router model, build number and when applicable Linux Kernel used.
2. NEVER use the router database
3. Supported devices (and most of the time an install guide) can be found at the supported devices wiki: https://wiki.dd-wrt.com/wiki/index.php/Supported_Devices
4. All builds are beta see the build threads on the forums for problems and be prepared to do serial recovery, builds can be found at: ftp://ftp.dd-wrt.com/betas/2019/ ( I have tested a lot of builds on a lot of routers and never had to do serial recovery, sometimes TFTP recovery, but maybe I am just lucky)

Regarding point 3 see this post with some information about the R7800:

This is the method that I used to replace the stock firmware with the latest Brainslayer build (.img file). It worked perfectly. msoengineer documented it just 2 pages ago in this very thread and it definitely works great. Here is a copy/paste of his post.

msoengineer wrote:
For the future, you need to get the R7800 in TFTP mode first...this is not like the old broadcom days and peacock thread....


To get the router in TFTP mode:

Start with the router off.

1-plug the Ethernet code between laptop/desktop and Wan. If you don't plug it into the wan port and try using a lan port I found that the router doesn't want to enter into tftp mode.I believe you have about 5 minutes before this mode times out and then boots the router back to normal operation.

2-find something that can push in the reset button and hold down the reset button and power on the router. Keep holding down the reset button as the router boots up.

3-watch the power LED, it will flash orange six times, or so, and then it should start to flash White. Once it starts flashing white you can release the reset button and then you can push the IMG file via TFTP.

I'm clearly ignoring all the steps you need to take to make sure that you have tftp set up the right way:

Hey everyone who commented,
Thanks for the assistance. I was able to reflash the OEM firmware back onto it, and I am going to do a more in-depth dive into the firmware versions before I just grab the router database recommended version and push... Late night "I'm tired of the issues with the current firmware" jump is not the right frame of mind to reflash router firmware... >.<

If anyone has a personally recommended version for the Netgear R7800, and why that version is the best; I'm all ears.

I am going to just list out the features I want in no particular order. Below is as much my brainstorming/feature desire as anything:
* 802.11ac
* MU-MIMO
* Beamforming
* Definable QOS
* VPN integratability
* DDNS capabality
* VLAN segregation capability
* DHCP with IP reservation capability
* Manual Port forwarding capability
* SSH remote interaction
* More as I think up things I want to be able to do.

I would start with "v3.0-r37495M kongat"
the firmware version is a bit older but "rock solid"

the last Kong build is still running well, sadly you can find it only on demand....

all those futures are very questionable how you gonna use them, as some of them are
settings dependant, some of them are client dependant...MU-MIMO works only on Stock firmware
and only with a specific clients in specific scenarios, that can take benefit of it, same is with Beamforming ....
Dynamic QOS ??? I haven't seen such a Dodo...on DDWRT is QoS with various prioritisations...
VPN works very good on R7800 but it depends what settings and encryption you want to use...
All the rest are working and R7800 is one of the best units around...

otherwise R7800 on stock Netgear firmware sucks badly...
