How to revert from OpenWRT to stock on r7500v2

I'm running into issues with the .img files both from here and from netgear.  When I try to downgrade to stock, I get an error that the format isn't supported. 

I'd appreciate any info you can provide.  It looks like the .img format is for upgrading from stock firmware, but I'm not sure how to generate a downgrade from the stock .img file to whatever openwrt is expecting.

"sysupgrade-compatible image" is what is called for.

"This is what I got in response to asking the lead dev of the OpenWRT port for the 7500v2 how hard it is to switch back to the stock/OEM Netgear FW on the router: "I often switch between openwrt and stock FW without any issue.""

I had a real rough time reverting back to the OEM with a TP-Link some time ago. I am on 1.0.2.2 for the R7500V2 at the moment. Here is hoping for DDWRT support for this Netgear.Does this OpenWRT firmware do anything for you?

Main Router: Netgear X4 R7500V2
Bridge: R7500V2
Tivo Moca: Actiontec
Repeater Bridge: Netgear X4 R7500V2

1) Setup an interface with an IP address of 192.168.1.x/24 (x = anything except 1) on a computer cabled to the LAN ports of the router

2) download most recent firmware zip file - unzip

3) reboot router

4) tftp the .bin file from the firmware zip to 192.168.1.1 early in the router's boot process.

I've tried uploading the .img file from my computer to the router using TFTP and as best I can tell, there is no TFTP daemon running.  I keep getting connection errors, but I can ping the router fine.  Any suggestions?
