How to Backup & Restore EFS Partition [IMEI] for Samsung Galaxy S5 [ALL Variant]

EFS partition contains a lot of important data about your phone, such as WiFi/Bluetooth MAC's, IMEI, others.
It's highly recommended to backup EFS partition if you own a Samsung galaxy S5. If one day your phone's EFS partition is corrupted, your phone's IMEI will be changed to "NULL NULL" and you will face "Not Registered On Network" problem and you won't be able to use your phone correctly.

This tool will allow you to backup the whole EFS partition of the galaxy S5 in one file, to restore at anytime and fix "Not Registered On Network" problem.

  • Installed mobile USB driver or Samsung Kies on your PC.
  • EFS backup/restore tool

Steps :
  • Download and extract EFS backup/restore tool
  • Enable USB debugging, then Connect your phone to PC via USB cable
  • Open the extracted "EFS_Backup_Restore" folder and double click on "EFS.bat"
  • For LTE variant : choose option (1) to backup and option (2) to restore.
    (SM-G900A, SM-G900F, SM-G900M, SM-G900P, SM-G900R4, SM-G900T, SM-G900V, SM-G900W8).

    Well the problem with my phone is that it wont run a sim card and shows no IMEI and no Baseband. I just bought it 5 days ago . When i ran it for the first time everything was working perfectly even the sim card. But afterwards i charged it for 3-4 hours and when i switched it on this problem occurred.

  5. No error mean there is no problem with this tool

  6. I'm sorry to tell you that this tool and any other tool (backup/restore efs) won't help you to fix your IMEI
    This tool helps only if you have a backup file
    Try to flash a stock FW

  8. - Every phone has its own file
    - Maybe help to fix it

  10. Qaisar Ali Shah15 June, 2014 18:38

    So there's no solution to it

  11. Unfortunately, no solution until Samsung update your phone modem

  12. Qaisar Ali Shah16 June, 2014 20:52

    i cant update my phone either. any solution to that? ...Its says registration failed

  13. hello, my phone has a region lock and i tried to unlock it by rooting the phone. It started and failed several times before it finally got rooted. After that when i dial *#06# imei appears as it is but when i dial *#0011# i get IMEi certi fail. I reverted back to stock ROM, in fact the official correct ROM but it still fails. Initially i get a Sim Network Unlock Pin Dialogue box but now it doesn't show up. I dont know whether it has something to do with the IMEI certi fail. Please help as i Now have a code to fix this region unlock. Thanks. Awaiting reply.....
