I have searched and can't seem to find anything on how to get my WNDR4000 back to stock firmware. I am currently using build NV64 19342 Mega and can't get it to see my NTFS USB drive. So, I want to change to stock.
The basic process is this:
1.) Download the latest Netgear Firmware ver.18.104.22.168 to your home folder
2.) Set static IP on wired PC (ip:192.168.1.10 mask:255.255.255.0 gw:192.168.1.1)
3.) Do a 30/30/30 and set the password on http interface when finished
4.) telnet -l root 192.168.1.1
5.) On a linux desktop using atftp
atftp --option "mode octet" --option "timeout 180" --verbose --trace --put --local-file ~/WNDR4000-V22.214.171.124_8.0.71.chk 192.168.1.1
6.) Wait 5-10 min & the router is ok
Reboot router, Clear browser cache and return Static IP on computer to DHCP.
Reset the WNDR4000 to restore the default netgear password "admin/password"
From a Telnet session to show the randomly generated password.
telnet -l root 192.168.1.1
nvram show |grep http_username= && nvram show |grep http_passwd=
