==Backup the NVRAM partition==
Before flashing the device with a different firmware it is a good idea to backup the current NVRAM partition. This partition stores key information for your Gemini, including the IMEI number. If it gets lost or damaged, your Gemini will not be able to take or receive calls.
The provided flash tool is already configured for your Gemini. To create a backup of your NVRAM partition, just click on the '''Readback''' tab and then on the '''Add''' button. A row will appear in the table as in the following screenshot.

Once rebooted, the flash tool will detect the phone and will write the NVRAM partition on a file on your hard disk called NVRAM0. It’s a good idea to keep this file as a backup.
