Flash Netgear XR500 Firmware onto the Netgear R7800
For those Flash hackers out there,  Xvortex has produced a firmware from the Netgear XR500 to Flash onto the Netgear R7800 [Image: wink.gif] 

Both routers have nearly identical hardware and the XR500 has a higher value of Flash (256Mb), same RAM, CPU and Wifi chipsets and seems to be working a treat.

I got hold of the following file from a well known coder 'Xvortex' - 'R7800-V2.2.1.10.img' and tried the usual thing with tftp2.exe and could not get the tool to flash the firmware to the router.

I did the normal, got router into recovery mode by depressing reset button, power on router and wait until flashing Orange Light Started to flash White.

Connected Ethernet cable from laptop to Router and made sure Ethernet Connection had Static IP address assigned to it of , but still not luck.

I disabled Firewall and all that normal stuff, but still no joy.

So I decided to go back to basics and flash from CMD line with my Windows 10 Dell Laptop

On my laptop, I navigated to Control Panel > Programs and Features, click on Turn Windows features on. The I selected TFTP Client from the check list. Click ok then.

I then opened a command prompt window. hit enter. at the command prompt write "cd desktop" (remove quotes). Finally, type "tftp -i put firmware-file-name" (remove quotes) and hit enter. I then waited several minutes and router should reboot itself if all goes well.

Actual Command I used was tftp -i put R7800-V2.2.1.10.img and make sure file is located on your desktop

Unsure if Netgear XR7800 ( [Image: biggrin.gif] ) can be updated with newer Stock Firmware for the XR500, so if any body else gets a chance, let us know as I am still getting my head around DumaOS and Geo-Filters etc?

This Forum was originally created to provide a means to allow users of ASUS (SOHO) Routers - both Wireless and xDSL (modem) based to freely communicate within a Community type forum where members can work together towards sharing experience, knowledge and ideas, I have recently also been asked to include Netgear and AVM wifi / modem based routers for discussion. All I ask is that we are all fair and reasonable, we try to add value where we can and not use this forum for other non community agendas and lastly, please feel free to dop me a message offline if you feel in anyways I can improve upon this site etc.
