Saw an LG G7 with the serial number blank/unpopulated. What does that mean and can it be restored? IMEI and everything else looks normal.

All of that is nvram data, it is all stored in the efs partition.
Serial number is not really important as its there for verifying when needed. IMEI is needed to connect to a network.
You can always use a app like cdma workshop to fill the serial number back in if its still on the case.
Thanks for the tip. Any other option for reflashing serial number? Can't seem to find a current version of CDMA Workshop and not sure if that would work with G7.
In order not to create a new topic, I will write here. I have the same problem, the erased serial number.
Is there a real working way that will restore the serial number? Thank.

What can I do to get original imei?
Now mount Android 4.1.2 xxdlk7
Sorry for my bad english
You didn't properly upgrade and downgrade...or maybe something went wrong during the process..Whenever you install a ROM you should always take a backup of your EFS partition in order to avoid such issues.I am sure the DITTO Rom installer must have generated a backup of the EFS while flashing/installing it ..if that is so you will find that in the internal SD card mostly. Secondly,I don't know about other but i have faced this issue with my Samsung Galaxy S2 ...Sometimes the IMEI is proper in the partition but it shows it to be wrong..and the network connects !....and the imei shows proper on restart / flashing other ROM...
This might help !...
1.Search for the EFS restore image created buy the ROM flasher..into ur Computer system
2.Follow this guide http://forum.xda-developers.com/showthread.php?t=2088809 and check if the IMEI comes proper..if it doesnt then use the EFS backup to restore in that case refer this http://forum.xda-developers.com/showthread.php?t=2255943
after kies upgrade
Serial Number: 00000000000
Imei: 004999010640000
using a tool for recover imei
Serial Number: 00000000000
Imei: 004999010640000
but phone working network working message working ecc
the network might evict you maybe later..or i dont know its wierd needs the attention of some person with more knowledge...
Hi there,
Need a help of someone good at working with G4 unlocking. Here is the story of whole problem.
I bought an LG G4 from my local market. At the time of purchase it was rooted but not updated, so I thought to update it. I tried to flash it with Marshmallow kdz available at storage cow with H81520B_00, but may be I flashed my phone with wrong kdz file (as I was not aware of matter at that moment) which was not supported by my phone's model as my phone was H815T (HKG version). The flashing of wrong KDZ file changed the ESN, IMEI & MEID of the phone and replaced them with something that is blacklisted in international phone database. because of this reason now whenever I try connect my phone to the network with the sim installed, it doesnt show any connectivity and displays that service is disabled on the phone.
After this incident, I re-flashed my phone with correct kdz available for H815T model but the problem still persists.
Then in many forums I tried to find the solution to revert back my phone's ESN, IMEI & MEID back to the values printed on the back sticker of my phone pasted under the battery. Somehow I was successful to revert the IMEI of the phone back to original but I am unable to change the ESN and MEID values.
I have tried many ways. I tried to use EFS Explorer of QPST but in that, I found that the NV folder which includes the ESN and MEID values is locked and by applying all my efforts and searching everywhere, I am still unable to unlock this folder.
I tried DFS CDMA Tool, it shows my phone's info properly, but when I try to write the old values to my ESN and MEID areas, it says that the values have been written successfully, but when I try to read the values again to check whether they have really successfully written or not then the tool shows the previous corrupted values again.
I tried EFS Professional & CDMA workshop for the same reason and it too showed the same response as DFS.
I need a help from someone who can guide me that how can I unlock the NV folder of my phone and write the correct values of ESN and MEID of my phone back to it so that it can connect to the cellular network.
Apart from cellular network connectivity, all the functionality of the phone is perfectly fine.
Exactly same problem with my G4, only difference is that it connects to network and disconnects again and again. I am able to make/recieve call and sms when outdoors. Ut randomly drops signals even outdoors
I need help. I have done something to my phone and now i cant see my serial number and i have a invalid IMEI number. What can I do? I have tried a lot of things that people suggested and nothing works. I cant use kies3 or smart switch. and i have no backup of anything they all was corrupted.
Hello,
I have a refurbish LG G3 phone ... If I am looking system information or checking IMEI, or checking behind bettery, it is a D850. But ... if I am looking https://www.imeipro.info/, the serial number is not the one I can find using software that are showing serial number or on device list on ADB ...
So I was wondering, is it possible that when they 'clean' the phone for refurbish, they change things and it is not a real D850 ? Something can explain the difference between system information that is saying D850 and serial number that is not the same on imei checker ?
I try to install TWRP using D850 image but it is not working ... but maybe it is not working because of refurbish phone ?
