cannot use nmrpflash on my netgear r6220

[ThomasKub]

everytime i try to use the command:
nmrpflash.exe -i net2 -f R6220-V1.1.0.68_1.0.1.img
in my command prompt i get this return:
No response after 60 seconds. Bailing out.
ive already tried to add the macadress but it seems not to work anymore.

On this router is openwrt installed.
Hope you can help me.

How did you connect the router to the device running nmrpflash?

[ThomasKub]

I use ethernet Port 1.

And a cable goes from port 1 to the network interface "net2"?

You need to run nmrpflash in the following manner:

• Turn off the R6220
• Start nmrpflash
• Turn on the R6220

Also, add -vv when running nmrpflash and post the output.

Hi, I have similar problem with R6220. I want to get back from openwrt to stock.
I've done following:

1. Connect laptop to R6220 via ethernet cable (to LAN1)
2. Turn off the R6220
3. Run:
   sudo ./nmrpflash -i enx000ec6a477d0 -f fw.img -vv
   on laptop (yes enx000ec6a477d0 is eth card)
4. Turn on the R6220

That give me:

Please try with -a 192.168.1.1, and set 192.168.1.2 as the IP of your network interface. Does that work?

[wiewiur]

Worked!
I've done it but with 192.168.2.1 and 192.168.2.2 and got:

Reboot your device now.

Thanks @jclehner !

I think its good to add this "Received keep-alive request." message to documentation, I was a little bit confused - should I restart router or not. I think I'm not alone.

[jclehner]

I've finally released 0.9.13, which fixes "Network unreachable" error described by @wiewiur. Closing this.

[limsko]

@wiewiur you have saved my Day. I was rebooting router during Received keep-alive request instead of wait.
After reading your comment I gave my router more time to finiah job. Flashing was successfull.

Guys can anyone please help. I’m unable to pass No response after 60 seconds. Bailing out. It is for my XR500 that has a constant red and white light active on power light

[NGOCodes]

Same issue here, mines bricked and I get the bailing out message

[jclehner]

You could try blind mode (-B option), but if that doesn't work, it could mean that the bootloader itself is corrupted. In that case, nmrpflash won't be able to unbrick your device, unfortunately.

Also, please don't hijack closed issues, but instead open a new one.
