I tried to install the 19.07.3 chk file in the OEM ui, but it is failing. Then i downgraded all the way to 1.0.9.32 version and it would still fail. A DD-WRT chk worked. Is there a specific version to be on for the chk to work, or I missed something.
I tried nmrpflash and it will say OK, then continue to boot in the netgear interface. I tried with -B, with -a and -A , without any option also. it always reboots in the netgear interface.
I have not open it yet to put the serial in.
