Router Firmware Re-flashing Problem

I installed the OpenWRT firmware on my netgear wndr4700 router to see what I could get out of it; I decided to go back to the default netgear firmware, so I tried to follow the instructions here, but its been giving me problems

first off, I open the ipv4 settings on my ethernet properties, and I change the ip address to 192.168.1.10, the subnet mask to 255.255.255.0, and the default gateway to 192.168.1.1, then after saving the settings I run the tftpd64 client, select my ethernet as the server interface, and the other fields as it should. I got the netgear firmware file on me, I run the client, I power off my router, wait 10 seconds, power on, and wait for the power icon to start blinking

problem is, when the power icon on the router starts blinking, the server interfaces changes from the ethernet to something called software loopback interface 1 (ip address 127.0.0.1), and I quickly change it back before the router fully boots, click put, and it keeps giving me an error (something something 10025 error something) saying it fails; when I re-check the ipv4 settings on my ehternet, the default gateway field keeps going blank when my router boots

to those who can help me with this, please tell me what im doing wrong and how to fix it (hopefully without bricking the netgear router

Hi BrokenDaily.

One possibility, with your OpenWRT firmware installed what address did you give the router?

Said another way, if you want to talk to router through a browser what address do you use?

You have to go to the Openwrt web site to figure out how to go back to the original firmware.

Net-gear is only going to show you how to change their own firmware not somebody Else's

With that said here is the page I think is for your router, But I don't see a way to flash the old firmware.

Openwrt has been recently upgraded:
The current stable version series of OpenWrt is 18.06, with v18.06.1 being the latest service release of the series. It was released on August, 18th 2018.

The new version has a far better Linux kernel that what Netgear firmware has, Newer is better more secure

• Linux kernel updated to versions 4.9.120/4.14.63
• Security fixes for Curl, Mbedtls, OpenSSL and the Linux kernel
• Binary builds for the at91 and ath25 targets
• Updated mwlwifi driver
• Improved input validation for rpcd uci ubus calls
• Crash fixes in libuci
• Assorted bug fixes in netifd

Your best bet is to see if you can upgrade to version 18.06.1 and see if you like that better.
