I downloaded the factory-to-ddwrt.bin.
I re-set the router to default, pressed reset button for 15 seconds.
Did Router Firmware Update, selected the factory-to-ddwrt.bin file.
After a minute or so I got a successful update popup notice.
The router re-booted and came back up as the factory Linksys firmware.
I did the on-off for 2 seconds, 3 times to change partitions.
It sill comes up as Linksys firmware.
I did this 6 times.
I never got a DDWRT screen.
I have half dozen old WRT54GL with DDWRT and they all flashed flawlessly.
Can anyone get me pointed in the right direction here? I am sure I am missing something.
Thank you!

Avoid Chrome or Chromium browsers. Disable any add-ons, extensions or plugins & clear all history.

Pale Moon, Waterfox (Classic 56 or 3rd Gen 78), Firefox ESR 78 or Release 84 (Release version is YMMV)

Linksys WRT1200AC factory stock firmware upgrade page has a file size limitation a little over 32MB.

Install DD-WRT with r34411 factory-to-ddwrt.bin

https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2018/01-07-2018-r34411/linksys-wrt1200ac/

Then upgrade DD-WRT to r44048 with ddwrt-linksys-wrt1200ac-webflash.bin

https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2020/08-02-2020-r44048/linksys-wrt1200ac/

During a firmware upgrade leave the Web GUI dropdown option selected "Don't reset" so ignore it.

Hard reset is hold the physical pinhole reset button 7 to 10 seconds while powered on and after full boot.

CLI reset is Telnet as root then "nvram erase && reboot" either way but after successfully running r44048.

Confirmed hard reset is 10 seconds. Forgot to mention a couple things which may or may not be obvious.

It is recommended to flash over Ethernet connected to a LAN port, not over WiFi (disable client adapter).

There might be a need to disable any OS software firewall or security software which may be interfering.

r34411 upgrade successful but r44048 upgrade failed. I will just leave r34411 as is. I am completely ignorant of TFTP so I am very apprehensive of using it.



It is so fast compared to DDWRT on my old WRT54GL!

Thank you so very much! I really appreciate you taking the time to get me up and running!

Well, crap! I see what I did! I completely overlooked your instruction "Then upgrade DD-WRT to r44048 with ddwrt-linksys-wrt1200ac-webflash.bin".

I tried it from the upgrade button in r34411 and it failed. Sorry, I am a dummy!

I'll try that after morning coffee.

The only advice I would add to Blkt's is to allow the update session to complete with no interaction once started.

At one point in the update process a screen will pop up with some info and a "Continue" button. Don't press the button. Just let the update continue, ignoring the pop up, until the GUI pops up.

It may take a minute for the GUI to pop up but it will on a successful update. Allowing the update to start/finish with zero interaction has worked well for my 1200 v1''s.

I tried the ddwrt-linksys-wrt1200ac-webflash.bin and it failed as well. I let it go for almost half hour and came back to see an update failed message. Tried it again and same thing. I guess I will just leave it at r34411.

Thanks to everyone! I really appreciate the help. I guess the old WRT54GL routers got me spoiled with their simplicity and ease of update. I still have one connected to a yagi external pointed toward my shop but it is almost 13 years old! I want to replace it with this WRT1200AC when I am comfortable with it's operation. Several years ago, I allowed my neighbor to piggyback off my internet with another old WRT54 and that thing sat in my attic running for 4 years and I never touched it. I hope this 1200 is half that dependable!

Cheers everyone!

Which web browser are you using? Did you attempt CLI flash? Giving up far too quickly.

Thanks for the super fast response!

I tried Edge and Firefox. I read not to use Chrome and my understanding is that Edge uses the Chromium engine as does Brave so I went back and with Firefox.

I don't know what CLI flash is. Could you enlighten me?

I hate to give up on anything so I will try!

Constipation of the brain!

Ah! OK. CLI Command Line Interface.

I connected via Putty but I don't know the login or password or the proper commands. Do you have a link you could share with me with that info?

Don't know if your Firefox browser is ESR 78 or not but there's a list of suggested browsers in first reply.

CLI flash: connect with PuTTY via Telnet to 192.168.1.1 with username root and your password.

Type this command to determine the current active boot partition.

Code:
ubootenv get boot_part

The output will return CRC then a value of 1 or 2. Remember this value.

Code:
cd /tmp

wget ftp://ftp.dd-wrt.com/betas/2020/08-02-2020-r44048/linksys-wrt1200ac/ddwrt-linksys-wrt1200ac-webflash.bin

write ddwrt-linksys-wrt1200ac-webflash.bin linux

Then set the boot partition opposite of the value returned earlier from the get command.

The example below is if the get command returned a value of 1. If get returned 2, set 1.

Code:
ubootenv set boot_part 2

reboot

Excellent! 👍

Thanks so much for your patience!

I am not running Firefox ESR. I am using Firefox Browser 84.0.2

I'll give it a go.

Well something went wrong.

I followed the instructions to the letter and all seemed to go ok.

I typed reboot and the router rebooted but now the yellow internet light is flashing. I cannot get a response through my browser nor can I connect through putty. I did a reset and still nothing. I turned it off and on three times and nothing.

Ideas?
