Hi Everybody,

I tried to flash a Linksys WRT1900ACS V2 (model no).
The original Linksys firmware I've bought is 2.0.0.173388 and it was not upgraded to the latest Linksys firmware.
I used DD-WRT beta r36698 using different browser (Egde/Firefox) without any success.
All the time the router boot using the original firmware.
I tried to shortly switch 3 times on-off the router to force it to boot from other partition. I also use Troubleshooting --> Diagnostic --> Restore previuos firmware. Nothing. The router boot-up using Linksys firmware.
Any advise will be appreciated. Thank you!

After some trying I found this post:
https://teledom.gr/tech/dd-wrt/dd-wrt-wrt1900acs-v2-multiple-wifi-ssid-multiple-subnets-vpn/
So, the Linksys WRT19000ACS v2 (in my case firmware 2.0.0.173388) cannot be flashed using DD-WRT factory-to-ddwrt beta r36698. According to the article mentioned before you can use factory-to-ddwrt 11-16-2017 beta r33772 and after that use webflash binary for r36698.
Probably something is wrong in the factory-to-ddwrt r36698. Maybe this will help somebody or the next beta release will solve this.
Have a gook luck!

I flashed 36698 onto my WRT1900ACSv2 from the current factory firmware (to which I updated first) about a week ago. It took me a few tries, I think because initially I didn't have my computer plugged directly into the router. I had a mini-switch between them. Or maybe it was something else. But it was possible. I'm using the router now with no issues.

I have a WRT1900ACv2 that also wouldn't update to the dd-wrt firmware (always loaded to stock after upgrade). Uploading the 11-16-2017 beta r33772 firmware worked for me as well. This should really be added to the wiki or the dd-wrt router database site or corrected in the firmware if possible.

This is the direct link to the firmware for the WRT1900ACv2. http://ftp.dd-wrt.com/dd-wrtv2/downloads/betas/2017/11-16-2017-r33772/linksys-wrt1900acv2/factory-to-ddwrt.bin
