EFS pro is a tool developed by lyriquidperfection that can backup and restore our Samsung Android device’s EFS settings folder. This contains very critical phone specific information that include IMEI (encrypted in the nv_data.bin), wireless MAC addresses, product code (also in the nv_data.bin) etc. which is very much required in order to use your device otherwise if this information is missing you may brick your Samsung Android device.
Below I have given the download link for EFS pro just download and install, after which you can use it for backing up the EFS folder and restore it as well when required.
You are recommended to check the latest version of EFS pro on official development page and also don’t forget to donate even small amounts so that our developers can continually provide us such Android tools.
