Restore EFS on Redmi Note 3 (Snapdragon Variants Only)

Do these instructions if you erased your EFS or is corrupted, if not then follow the next guide to change your IMEI number. Sometimes you lose your IMEI only and not the whole partition.

Instructions:

1. Download this file: EFS Backup(Kenzo) EFS Backup[Dump][Kenzo].rar

2. Extract the Dump backup files and flash them using this commands:

   Fastboot flash modemst1 modemst1
   Fastboot flash modemst2 modemst2

3. The final step is to reboot, and you will have new EFS partition.

Note:

• Your IMEI and Baseband will be shown as unknown if your EFS is erased or corrupted. The first thing you must do is to recover the EFS and then change IMEI. If your IMEI is shown as 0, your EFS is safe and probably your IMEI is gone. In that case, don’t recover EFS just change the IMEI number.
• In TWRP, backup of kate won’t show on Kenzo and the backup up Kenzo won’t show on kate, next you will try the dump flashing method or try changing the TWRP recovery.
• These instructions are only to restore your EFS partition, but the IMEI will be still gone, next step you must do is to change your IMEI.
• After flashing new EFS, your Mac and BT address will not recover. Android system will assign a software generated address to both devices. Even without the EFS partition, there will be a Mac and BT address assigned to your device, and they will work regularly.

16. Unpack Qualcomm IMEI Write Tool and start WriteDualIMEI(W+G_eMMC).exe (in case you want to write the MEID code, then use the “qualcomm Write IMEI MEID.exe” file.).
17. Simply enter your both IMEI codes and and press “Start” to continue. You should see a success message if everything was done correctly.
18. In the end we need to disable Diag Mode. Enter *#*#13491#*#* and tap on the last button (MTP,ADB) and press “Ok”.

Required Software & Files:

• QPST: QPST.WIN.2.7.429.rar
