Howdy all..

I have a r9000 running DD-WRT 37305. I've attempted to update to 40559 and it won't accept the update.

Using Chrome: DD-WRT U/I -> Admin -> Firmware Update -> "Don't Reset" and Browse/select the 40559 update file and select [Upgrade] button.

Timer counts down to zero and stays at zero. After waiting 30 minutes I power cycled the router and it's still at 37305.

I've had dozens of DD-WRT routers and have done plenty of upgrades. This one won't take an update.

Is there a tftp/ftp/scp/ssh method of updating?

The router database has deceived you.

ftp://ftp.dd-wrt.com/betas/2019/

ftp://ftp.dd-wrt.com/betas/2020/

I use 12-29-2019-r41813 for now.

You may want to try a different browser to flash, or just go straight to the command line method.

Waterfox Classic, Pale Moon, Portable Legacy 45 or 52

I believe R9000 has a TFTP recovery mode just like the R7800.

Command Line Telnet/SSH Method: use wget to download with a ftp or http link (not https) into your /tmp directory and then use the write command to write the file to linux.

I have that router and remember that there was DD-WRT version that would not update via the web GUI. I use SSH now to flash my r9000. That works well and I do not have to download the flash file, the router does it for me.

1. Open a command prompt
2. Run "SSH root@<your router IP>" (Make sure you spell "root" properly.
3. Enter your router password when prompted.
4. Enter "cd /tmp"
5. Enter "wget http://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2020/01-18-2020-r42015/netgear-r9000/r9000-webupgrade.bin" (Note 1: The URL is to the latest version as of this posting. You would change it to whichever version you are interested in. Note 2: The URL must be "http://", not "https://". I copy the link from the download page, paste it and delete the "s".
6. Enter "write r9000-webupgrade.bin linux" Note that the file name is from the end of the URL. "linux" is basically a 'target' command.
7. Enter "reboot"

Those are my steps.

Your'e going from a significantly old build to a new one and you should be resetting all the settings and starting over from scratch- There were changes to NVRAM mappings between that build and the latest and greatest. Next, use incognito mode to try and make updates. If that doesn't want to work, then TFTP is the final method to use as others have indicated.

When you put it into TFTP mode. There will be two sets of "fast" flashing of the pwr LED. Once you see the pwr LED go into the second set of fast flashes (faster than first set), the router is in TFTP mode (about 20-30 seconds of holding the reset button)(I forgot the flash count but I want to say initial led flashes are 7-8, then second set 5-6, then after that is the final fast set of flashes and it's in TFTP mode).
