Telstra Elite MF60 firmware update and unlock guide ( Not tested)

NV-Restore
I have made this tool to try and restore your IMEI and WiFi MAC address that are both cleared out when unlocking the MF60 with my patch.

You'll need to have your Channel1.nvm file that the firmware installer creates when updating the device. it's located in the same directory as where the installer was run.

I have not been able to test this properly yet, so feedback would be good.

I'm unsure if you can restore the IMEI number at all. There seems to be some type of safety feature which locks writing the IMEI number if one is already set. As I have an IMEI set on my device, I cannot test this feature (long story, but I'm putting off updating my 2nd MF60 until I figure out a way to save the old firmware, the first one died trying to flash a foreign firmware).
But since the firmware installer with my unlock patch actually invalidates the IMEI completely it might be possible to write one back.

You can also restore your Channel1.nvm file with the restore function, but doing this will remove the network unlock.

Steps to use this tool to restore your IMEI and WiFi MAC
Plug in your MF60
Click Select Com port - choose ZTE Diagnostic Interface
Click Load from Channel1.nvm - and find your file
Click Write to Device
Hopefully it will work.
