I managed to turn on the router

start the program then turn it off and on again

but it's completely blocking it's more than an hour

who is on the firmware update page and who is telling me please be patient what should I do?

the loading bar and finish for a long time

and nothing is not working on the internet on the pc

and every time I try to refresh the page

it recomposes the configuration at the beginning

it's like he does not record any of the information I give him

1. Were you finally able to flash with nmrpflash?
2. Did you wait for it to display Remote finished. Closing connection.?
3. In any case, run nmrpflash with -vv and post the output!
4. Don't just try net1, net2, etc. Use nmrpflash -L (without any other options) to print all network devices.

I had a lot of trouble with the short 5 second Window on an r6400v2 to get the session open. In the end I found that holding in the reset, starting nmrpflash, then powering on and releasing the reset seemed the most reliable. You Must wait for an orderly session close or the flash has not completed properly. Remember to upload the img or chk file inside the zip and not the zip itself. Win 7 x64

same issue there.
I connected the router from my pc ethernet (net4) to lan1 port (router)
i also set the ip to 192.168.1.2 and gateway to 192.168.1.1 or 192.168.2.2 and 192.168.2.1 ( no difference at all)
if i start nmrpflash and the router is on:

c:\> nmrpflash -i net4 -f R6220.img -vv
net4: \Device\NPF_{4824445A-85E9-4EB1-AA2C-DF1966AD8765}
Adding 10.164.183.253 to interface net4.
Advertising NMRP server on net4 ... \
No response after 60 seconds. Bailing out.

If i switch off the router then start nmrpflash :

c:\> nmrpflash -i net4 -f R6220.img -vv
net4: \Device\NPF_{4824445A-85E9-4EB1-AA2C-DF1966AD8765}
Adding 10.164.183.253 to interface net4.
Failed to bind after 5 seconds: bind: The requested address is not valid in its context

Ok I DID IT!
I managed to do it following these steps:
1- switch on the router
2- start nmrpflash and wait till Advertising NMRP server on net4 ... \
3 - switch off the router and then on.
4 - Done.

I'll investigate. In the meantime, try this: 1. Turn on the router. 2. Start nmrpflash. 3. Power cycle the router. EDIT: Ah, silly me. Didn't see your edit ;)
