How To Backup and Restore EFS and IMEI Partitions on Galaxy S7

EFS and IMEI partitions are of grave importance to those who want to play hard with their Android device. Especially, when you’re rooting your device and flashing various custom images/ROMs. Just imagine that you have flashed some fancy ROM on your device and on the next reboot, you can’t make any calls or connect to the Internet. It will be quite frustrating to deal with such issues.

In Samsung devices, EFS partition stores the IMEI, wireless device MAC address, baseband version, product code, system ID and NV data. So, if the EFS partition gets corrupted during the flashing, you will face connectivity issues. Errors such as “Can’t connect to network” or “Unable to connect to the internet” were some of them. You can’t even get the IMEI number and baseband information in About Phone section of your device. So, it’s a better precaution to make a backup of EFS and IMEI partitions.
