EFS Pro v2.1.80 BETA Free Download | backup & restore EFS / IMEI on Android phones

How to backup & restore EFS / IMEI on Android phones using an easy steps guide. Similar to the partitions on your computer, the Android smartphone has partitions. One of them is an Encrypted File System i.e. EFS. It is related to networking and communication within Android phones. Moreover, the EFS folder is located in the system directory of your phone and contains some important information about your phone’s IMEI, Wireless Product Code, System ID, and NV data.

Besides, EFS can handle all the functions related to connectivity including Cellular Network, Wifi, Bluetooth, IMEI, Network Unlock Information, etc. Hence, for any reason, if this EFS data gets corrupted then your device will be completely useless and will no longer be recognized by your carrier. Also, you’ll be not able to make or receive calls, send or receive messages, connect using Wifi, Bluetooth, etc. Your IMEI will become null. There are many reasons because of which your EFS data can get corrupted some of them are listed below:

  • Installing custom ROMs from unknown sources may corrupt EFS data.
  • Installing corrupted Kernel or unsupported Kernel may also lead to the corruption of EFS data.
  • In rare cases, manually upgrading or downgrading official firmware may also corrupt EFS data.
