Backup Galaxy S5 EFS and IMEI with ease
We all know that the Encrypting File System aka EFS partition has highly sensitive data, so before playing with custom roms, mods, tweaking and so on on your Samsung Galaxy S5, we should be aware of the fact that there is a possibility for corrupting the data in the EFS partition – in that matter we should back it up.
So, we recommend you to start any procedure you might have in mind only after performing a backup of your Galaxy S5 EFS partition. This partition usually has the smartphone’s specific data such as product ID, IMEI, baseband version, but this rule is not available for Qualcomm devices.
In this case on your Galaxy S5, the IMEI number is no longer stored on EFS partition, so making a backup of efs.img is not enough. A full backup of IMEI means taking a backup of efs.img, as well as Modemst1 and Modemst2.
