R7960p Router will not update firmware

Was able to update my router that was stuck on R7960P-V1.4.1.50_1.3.10.

Used the nmrpflash method. Updated to R7960P V1.4.1.64_1.3.25 then used the Netgear router software to update to R7960P-V1.4.3.88_1.3.50.

Method is here:

I put the firmware file in the same folder as the nmrpflash.exe file.

Was using my router as an endpoint, initially had failures until I noticed after the attempts my attached computer ip address was changed from 192.168.2.5 to 192.254.177.93, since my router was set up as an endpoint and assigning. Checked by running the nmrpflash "-L" command to check the connection name <net9> and ip <192.254.177.93>.

used the -a and -A commands to assign the ip address on my computer and target router. -A 192.254.177.93 and -a 192.254.177.94

ran the nmrpflash.exe with the the following command line and it worked.

nmrpflash -A 192.254.177.93 -a 192.254.177.94 -i net9 -f R7960P-V1.4.1.64_1.3.25.chk
