Hi
You do not need to use the flash utilities with MP2. Theu are only for MP1.
Which version MP2 do you have - Basic or Phone?
The device should be running a version of SECN (probably 2.0) when you received it - is that correct?
Assuming it is running SECN, then you can point your browser to the IP address of the device (10.130.1.20 by default) and access the SECN configuration pages.
To upgrade the firmware, go to the Advanced tab and then the Firmware tab.
You will need to use a .sysupgrade file and its md5sum checksum to do the upgrade.
Does that help?
Regards
Terry
