It’s a GT-N7105 – the LTE version.
Prerequisites:
* Get Samsung USB Drivers: http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows
* Put all the ROMs and zips you care about on your sdcard in a ROMs folder or something
- Follow the Cyanogen mod instructions to get the recovery rom in place:
http://wiki.cyanogenmod.org/w/T0lte_Info and http://wiki.cyanogenmod.org/w/Install_CM_for_t0lte - Flash the latest recovery-clockwork-touch-x.x.x.x-t0lte.img from here: https://www.clockworkmod.com/rommanager
You now have the latest ClockworkMod, so you can use that to install whatever you bloody well want.
3. Backup the EFS using ClockWorkMod or whatever else.

4. Reinstall phone drivers
Heimdall would have rooted your Samsung USB drivers, so use USBDeview to remove any previously installed driver relevant to the phone.
Plug her back in and install the USB drivers
