How to Backup and Restore Lost IMEI on LG G2

Rakesh | 10 Apr 2014 | Guides/ LG

Lost IMEI on LG G2

Losing the IMEI of an Android device is one of the most awkward situations a user can find him/herself fallen into. But why is the corruption the EFS partition and loss of IMEI is so serious an issue that results in a nightmarish experience? Actually, people do not feel bad because their device does not show that long series of digits that we know as IMEI, but because the corruption of EFS/IMEI leaves the device with no network signal or data connection at all.

All other functions work without a problem but a phone without a network is just a useless gadget without a soul. The cases of lost of EFS data or IMEI is commonly found on Samsung Galaxy devices but it can also happen to LG devices including the Nexus series.  The EFS partition on an Android device contains data like contains device specific essential information such as its IMEI, wireless device MAC address, baseband version, product code, system ID and NV data.

Recently, a friend of mine lost the IMEI of his LG G2. After struggling for some days and trying different things, he was finally able to restore lost IMEI on LG G2. If you happen to be an LG G2 user and are facing the same issue, the method described below might help you get back its IMEI. But before we learn how to restore lost IMEI on LG G2, let’s see first how to backup it.

Backup and Restore EFS on LG G2

  1. Make sure your LG G2 is rooted and you have installed TWRP recovery on it.
  2. Download LG G2 EFS backup script in flashable zip: LG_G2_Backup_EFS_Final.zip
  3. Copy the zip file to your phone.
  4. Reboot your LG G2 in recovery mode.
  5. Flash the LG_G2_Backup_EFS_Final.zip file using Install option in TWRP.
  6. At the completion of the installation, your phones EFS/IMEI data will be backed up to  /sdcard/EFS_Backup folder as efsbackupflashable.zip.
  7. Do not forget to make a copy of the backed up zip to your computer as a precaution.
  8. In case you lose your phone’s IMEI, you can flash the efsbackupflashable.zip file to restore your IMEI and NV data.

Restore Lost IMEI on LG G2

The method described above can help in restoring the EFS only if you already made a backup, but what about those who do not have an EFS backup? Don’t worry, we have a tested solution for you. The method given below has been tested on T-Mobile LG G2 D801 but it should also work on other US variants and International model of the device.

  1. Make sure your LG G2 is running the stock LG firmware. If your phone does not have the official firmware installed on it, restore it to stock first.
  2. Install the latest LG USB drivers on your computer.
  3. Now download the IMEI converter tool and unzip it: IMEI-Converter.zip
  4. Download QPST (Qualcomm Product Support Tools) and unzip it: QPST_2.7_378.zip
  5. Open the QPST_2.7_378 and run the setup file to install it on your computer.
  6. Enable USB debugging on your LG G2. You can find this option under Settings> Developer options.
  7. Connect your device to the computer.
  8. Run QPST configuration and click on the Ports tab. Click on Add new port option.
  9. Your current port should show as COM4/5.
  10. Select the port and click OK. The port should come upon active phones.
  11. Select the phone and click the Software Download option from Start clients menu.
  12. Now click on the Backup tab. You should see your phone’s port.
  13. Click on Start to initiate the backup.
  14. Now navigate to C:/ Program Files/ qualcomm/ qpst/bin folder.
  15. Run RF_NV_Manager.
  16. Click File> Read from phone. Your phone’s IMEI number should appear on number 550; NV_IMEI_I
  17. If you do not see item 550, do not panic.
  18. Click on File> Read supported RF NV items.
  19. Click on item 550. You would see 9 blank fields.
  20. Now run IMEI Converter.exe.
  21. Now type your phone’s IMEI in Enter IMEI field. You can find your IMEI on your phone’s bill or the box your device came in.
  22. Then click on <Convert IMEI> button.
  23. You should see 18 digits in groups of 9.
  24. In RF_NV_Manager program, click on Hex by Write NV button.
  25. In the 9 boxes, type in the numbers from IMEI converter starting from left. Type in the first group of two numbers in the first field, then go to the next field and type in second 2 digits.
  26. When you are done with doing this, click on Write NV option.
  27. Then click File> Read from phone.
  28. Item number 550 should appear now.
  29. Disconnect the USB cable and reboot it.
  30. Open phone’s dialer and dial *#06#. You should see your phone’s IMEI now.

    Two things missed for restoring the IMEI, 1. After flashing the stock firmware, when connecting USB, remember to choose the LG PC mode(the 3rd one) as the USB option, which would update the USB driver on the PC. Without that, the “LG driver” on your PC might not work. I am either getting no port, or a port with “No phone”.
    2. As moe mentioned below, when switching to RF_NV_Manager, before doing anything there, remember to set the COM port. The number after the COM could be any, 4/5 are just examples. I am getting 25 or 27 depends on which USB port used.

    For people getting errors at the RF_NV_Manager, click on Comport Configure (its an icon) and select COM 4/5 instead of blank. That fixed all the issues I had. Seems like this tutorial missed a step :p

      Hi, I’d be very thankful to find out- have you managed to solve this error. I have the same- at the end of the description it says- Command failed, reason other than NVM was full. My IMEI comes back from time to time though but mostly I don’t have which makes phone useless.

        hi,
        I believe you suggesting me to zero out IMEi first before fixing IMEI for my rooted LG G3 D851.
        So I google it and found your post here.
        I don’t have TWRP recovery installed yet.
        I am seeing 5 files in your google drive. can you tell me how to use those files to zero out the IMEI on my D851 ?
        thanks !

            The five files go in the EFS folder, and then restore with custom recovery, so does IMEI 0 and then write new imei

    Hello,
    great guide, greetings!
    I was looking since several months a way to access nv data because i accidentally jammed with my D802 leaving it without sensors. looking to logs i supposed it could be some nv setting which i altered, so i need a working phone’s data to compare to see if something related to it has been altered.
    So, i ask to everyone reading if i could have a textual dump of its d802 nv (obviously stripped of identification data).
    have a nice day!

    Hi Rakesh.
    I’m having trouble with Steps 8 to 10.
    On my Windows 7 laptop, my LG G2 (D802 international) uses the “com10” port by default, so I tried adding that to QPST. However it didn’t show up as active device. So then I used Device Manager to change the port to “com4”, restarted the computer and tried adding it to QPST again. My LG G2 still doesn’t show up as an active device, so I’m stuck.
    Help please!

    Hi Rakesh,

    I have Lg G2 D801. I was trying to upgrade android
    version using LG PC suite but unfortunately it not done and still showing LG logo on
    screen and mobile battery side is warm it seems that my phone is bricked. To
    resolve this issue I was contacted to LG service center. As per LG service guy
    the software is successfully installed but found some hardware problems due to
    which mobile’s IMEI, WIFI etc. didn’t work. I asked them why it could happen
    then he replies that it happen due to 3 or 4 times hard reset.

    Keeping above scenario my
    question is, is that true that hardware repairs required to resolve IMEI
    problem? Or this can be done via any software work. Please guide me because he
    is asking huge amount for repairs.

      Because you tried to upgrade the software, the EFS partition that contains the IMEI might have been messed up resulting in the issue.

    The only way I can get QPST to recongize the COM port is by changing the USB connection method to “LG Software”. But then, all QPST commands are failing. If I choose “Charge only”, the phone appears as ADB and no COM port is available

    I wanted to try another cleaver way that’s not listed because everyone getting errors at the last step here. I thought “why don’t we create a back up, edit that back ups information, and then restore the edited backup information to the phone”. however its failing too. 12% stops and Memory Restore Failed!: “Received an invalid command from the phone” when restoring the BackUp.qcn file.

    I created 2 backups 1 Changes.qcn to tamper with and 2 Original.qcn as a fail-safe original backup. In RF-NV mgr program/ file/ read from phone. edit the 550-NV_UE_IMEI_I Hex information … File/ write only listed NV items to QCN. choose the changes.qcn and filled out all fields that are (it gives errors if you don’t) and now you have a modified back up. I then go back to software information and the restore tab. I choose the Changes.QCN backup file SPC 000000 (no other numbers work if you do it shuts down the port for 10sec) allow phone/file esn mismatch checked/unchecked… ..and START….it Fails….. so I thought ok that didn’t work (lets just test the clean backup.let see if that goes through…. it fails too. same error. Received an invalid command from the phone” —- so why do a back up if it fails.. I have even open the QCN /read from QCN /option/ customized nv list just add 550.. /save and I get to 33% restoring the back up… in theory this should work if it completes successfully.

      This is a real bugger however getting closer to a solution, So I opened the QPST EFS Explorer and on the left File Trees I see folders for .efs_privite, nvm, safe, with a red / circle like you see on no smoking signs. I get an error trying to write the file just a .txt file to the nvm folder. I bet we are only able to read the information and do not have full write permissions for the NVM folder where the information is stored.

    Hi, when I try to write the new IMEI on my LG G2, it says: “Unable to write NV_UE_IMEI” (Command failed, reason other than NVM was full)

    Any solutions? Is it because my IMEI isnt 0? I want to change my IMEI, not to restore it from 0.

      Why do you want to change the IMEI?

        I’m only interested if its possible. I changed my LG G2 by vodafone and so the IMEI changed too. If I want to run my Navigon, it says, wrong IMEI. I think the registration of Navigon depends on the IMEI. I called Navigon but they say, I have to buy a new Navigon. Thats *****

        Hi Sandy, actually no. I guess the only method to write a new IMEI is to delete the old one. But that isn’t quite easy. Further you may brick your phone. So I dont know if its really necessray for you to change your IMEI.

      And have you made a backup? If not, how you want to restore from “nothing”? 😉

    Hi Rakesh

    Again I express my great gratitude for helping me with useful tips for my LG G2 D802.
    I like the extra security feature of knock code as it is more secure and simple to open to Home screen.
    But I like the swipe effect especially there are mind blowing multiple effects now. But opening the lock screen by swiping is not at all secure, Now at present, we can only use either of the two at the same time.
    My question is that is there anyway to use the nock code to wake up to the lock screen , then you use the swipe effect to reach the home screen, that it is more secure as well as use can enjoy the swipe effect as well. Kindly reply

    Thanking You
    Dr.saidalavi

    I am going to be attempting this when I get home, but for now my only question is where I can find my imei number on my physical device? I peeled the white sticker off the back when I got it, and it’s not on my bills record with T-Mobile, I couldn’t even find it when I removed the back case and looked by the battery, can anybody point out where I can find it?

    I’m trying to do step #8, but it doesn’t show up as a COM port. It shows up as an ADB interface. I’m at a loss now.

      Have you enabled USB Debugging? If yes, also try reinstalling the drivers and rebooting your device and PC.

        Ok, I can get it to recognize as a COM port, but when I run the RF_NV manager it doesn’t recognize the phone as a phone. I have tried going through the process in step 1 to flash factory firmware (which I believe I’m already on V8 anyway) but nothing works. When I do step 18 it says no phone is connected. I even broke down and went to Sprint to see if they could flash it some how, but they couldn’t. I don’t know, at this point I feel pretty defeated.

        Also I can’t get into the boot loader or fast boot. I can only get to download mode and recovery.

          Try flashing the stock firmware :https://www.droidviews.com/how-to-restore-lg-g2-to-stock-firmware/

            Tried that already. I get to step 16 of the .tot method and it fails every time and says check phone or dll

            Downloaded the stock rom zip file, and flashed it through TWRP. Now it’s in a boot loop.

            Doug Church says:

            Ok I managed to get it to work. I think you need to add a step in your process to download the stock rom zip file and flash it before trying the lg flash tool. Otherwise it won’t see the phone as the correct one.
