Dear friend,
I backed up my old WR740N device with the following versions:
Frimware Version: 3.12.11 Build 120320 rel.51047n
Hardware Version: WR740N v4 00000000

Now, I want to use this back up file to my new device with the following versions:
Frimware Version: 3.16.9 Build 160708 rel.68336n
Hardware Version: WR740N v7 00000000

I get error code 23003:
The configuration file restored unsuccessfully as the the hardware or software versions.

Attached is the backup file (need to unzip).

Please your help,
Ron.
