Netgear R6400 AC1750 - Firmware location on device by tftp upgrade

[steve564]

Hi,

I've some problems with my router (netgear 6400). I did some changes on the firmware and now I not able anymore to flash a new one. Admin interface is not working and bftpd is not running. Does anyone know where the uploaded/pushed firmware is located before the reboot?

I've root access to the device and I've tried to start the bftpd service but I get an error:

# bftpd
bftpd: segment_id:32769
shared memory reattached at address 0x40008000
421 Unable to open configuration file.

Now I'm looking for the location of the firmware or the update script/binary to trigger the upgrade. Maybe some has another option to flash a new firmware?
Info: I can't write into /etc /bin ... it r/o and a squashfs, remounting was not possible.

Thank you in advance.

Greets,
steve
