Netgear firmware unable to simulate in the firmadyne

[susantaroy2002]

Unable to simulate Netgear firmware, not if there any thing wrong on .chk file extension.

Here I am sharing some details about my blocker,

1. Tried on 2 netgear firmware version - "D8500-V1.0.3.39_1.0.1.chk" and "R7000-V1.0.9.28_10.2.32.chk"
2. attaching the error screenshot.

Please let me know if you need any further details to investigate this issue.

You are using an old version of fat. Consider updating it.

As for the actual problem, The file "run.sh" isn't generated, thats why its failing. You can have a look here how to proceed in such cases.

It also looks like there's a conflict with one of the previous runs.

Can you run the reset.py once and try it again.

@adi0x90 Hi Aditya, as per your direction I have tried below options -

First ran the download.sh and then reset.py , however still the same issue.

@susantaroy2002 : Can you share the firmware binaries?

@adi0x90 Hi Aditya, You must be busy in conference, just like to check if you have got a chance to see this

Updates on this one? I am trying to emulate Netgear firmware - R7000 and D8500 (latest versions). In both, I am unable to get any network interfaces. After running run.sh, I get kernel panic.
