Explanation
What is IMEI?

Why should I backup it?
When you start to mod your phone, sometimes may happen that you lose it (a bad flash, a wrong mod...) and without your phone is like this. Shortly, you lose mobile network forever.

The Qualcomm variant of Galaxy S4 doesn't have IMEI stored in EFS as most people think, it's stored in another place. Partitions to backup/restore are 8, each is required by the system to have IMEI. These are: EFS (there is IMEI's country code), modemst1, modemst2, m9kefs1, m9kefs2, m9kefs3, backup and fsg. It doesn't do miracles, so if you lose IMEI and don't have a backup, you're lost.


Features

• Complete IMEI backup


• Autozipping of saved partitions

Installation

1. Download tool from the link below


2. Put the zip file in your sdcard


3. Reboot in recovery


4. Install zip from sdcard


5. Choose downloaded zip file


6. Reboot system

Usage
When installed, the "imeibkp" executable goes in /system/bin. Obviously root is a must. This is not an app, so to run it you must use Terminal Emulator. It's very user-friendly and n00b-approved (joking :laugh:), normally you shouldn't run into issues while using it.

1. Open Terminal Emulator


2. Write su and press enter (this is to obtain root access)


3. Invoke this tool by writing imeibkp and pressing enter


4. To restore just invoke again imeibkp

In case you want to export your backup, it is in /sdcard/IMEIBackup and called IMEIBackup.zip (Internal Memory on PC through USB connection)
If you change ROM you'll lose this tool (you'll not lose a backup already made), in this case just follow again Installation steps
