Android is the most loved platform for mobile devices and one of reasons behind its popularity lies in its being an open source operating system. The possibility of gaining root access over the system files of Android device makes space for immense customization.
The root storage on Android devices contains several partitions that keeps sensitive data. Messing up with some partitions might make a device completely unusable. Since root access makes those partition accessible and modifiable. In this way, root access also increases the chances of messing up with those partitions.
The EFS partition is one such highly sensitive on Android, and especially Samsung device. The EFS partition contains data like device specific essential information such as the IMEI (International Mobile Station Equipment Identity), wireless device MAC address, baseband version, product code, system ID and NV data. It means that any disturbance in the EFS data might result in null IMEI and baseband version.
Connectivity services are the essence of a smartphone and losing the IMEI of a smartphone simply deprives it of all network and data services. If you are an enthusiastic Android user who loves to root and customize his/her device and play with custom ROMs and mods, corruption of EFS data is a probability you must keep in mind.
