Send it back to LG for repair. messing with the IMEI is illegal (short of backing up and restoring) and as such banned from the site.

My IMEI resetted to null

I just recently updated to docs ROM and when i check my IMEI it displays null.
It seems the update or kernal update has resetted my IMEI.
I would like to know how can i set it back, because i know my imei number. Is there any command i can set it to the phone.
please help me on this regard.
it's solved. what i did is i flashed the CSC & Phone files back to DDJP6 version. So this helped me to make phone displaying the IMEI.
The issue was last ROM update made some problem so android/phone was unable to read the IMEI number correctly, thus showing null..
Now it's working perfectly..

Need phone file to flash
I've got a Captivate i897 (flashed as an i896) that my brother bricked and we had it JTAG flashed. It now shows IMEI is null when you do a *#06# and when you do a *#1234# it shows PDA file and CSC file but PHONE shows as "unknown." When the phone boots up it creates invalid files in EFS due to not being able to read the IMEI. If I change the nv_data.bin from another phone and set permissions and ownership it can then get a signal and make calls but still shows IMEI as null. If I reboot then it goes back to not working. I need a PHONE file to flash in ODIN to fix it I think. If someone can tell me what PHONE file to flash and if I can flash just that FILE to fix the phone.

HELP! Corrupt IMEI, baseband, Serial Numer on S4 I9505

Hi all,
Sorry for the noob question but I have tried most of the repair suggestions in this forum all still could not get back the IMEI, Baseband, and serial number of the handset. Is there a way to program the original IMEI and serial number back into my Galaxy S4 I9505?
The handset had Hong Kong firmware 4.4.2 but with null IMEI, null baseband and wierd serial number. The handset is not IMEI blocked in Australia which I am trying to get it to work.
Would Chimera or Z3x software do this? Kies could not detect the handset for firmware update.
Thanks.

Already tried that. Flashed with stock Hong Kong firmware, modem only, etc and did not fix it.
Is there a way to find out the which is the original firmware for the phone as the previous owner might have flashed it with the wrong firmware?
:crying:
Go here and enter your IMEI. The result should pop up with a great deal of information about your device. Post the result, not including the IMEI itself, and we can figure this out for you.
If your IMEI just disappeared without you doing anything, then chances are you got a hardware failure and the your EMMC chip needs to be replaced.

Hi all,
I have re-flowed the MMC chip successfully. Is there a way to restore the IMEI and baseband without the nv-backup file?
Thanks :crying::crying:
Only if you used Wanam's EFS Backup tool to make a backup. It backs up not just the EFS partition, but the modem partitions and a few other hidden partitions as well. Otherwise you need to use methods we can't discuss on XDA to fix it.

How do I find out the if the modem and IMEI info were still there and not completely erased or gone by the previous owner. I received it with null/null IMEI baseband fault.
You already replaced the modem as it was suggested by someone upthread. That would take care of the modem. There's no way to know whether the IMEI is present or not. It probably isn't present, in which case it needs to be rewritten.

I think the IMEI info is lost so I would need to rewritten as I don't an NV_backup copy
The NV backup isn't present in the /efs folder on Android 4.4.2, at least from what I've witnessed on my own device. That's why I've switched to using Wanam's EFS Backup tool from Samsung Tool as it backs up the hidden modem and EFS partitions where the IMEI actually is stored.
If the IMEI is completely lost, you'll have to take the phone to Samsung for service. As mentioned upthread, there are other methods to fix this, but they can't be discussed here.

Thanks, in my case the modem and IMEI are already corrupted without an EFS backup so how can they be restored except for re-writting the IMEI ? I will look into Wanam's EFS Backup tool to see if I can salvage this mainboard.

(HELP) with NV DATA

Hey Guys I need some help with Nv data (EFS )
The NV data baseband is I9500UBUAMDE nonetheless my firmware baseband is I9500UBUGNJ1
I think this is why my phone do not have a stable conection with cel-towers...
So I need to know, how to update the nv data without corrupt it?
Kindly regards,
AG
Just flash a stock ROM using Odin. This will ensure that the bootloader and modem match.
Already did it some many times... Without results...
The phone is missing the imei and MAC address?
No one is missing...
Phone signal Goes out and in.
However while the phone has signal. I can call and navigate on internet..
Do you need the efs folder?
If the phone has an imei, then it seems like the efs folder may be fine and something else is happening.
So flashes are successful in Odin?
Could the phone be blacklisted? Was it ever dropped? Tried a different SIM card? Tried our SIM card in another phone?
Ok, I have to be honest... I was on 4.4.2
I try to use galaxysim unlock. However EFS was v2 and I restore a v1 efs folder in order to unlock the phone. It works. However after upgrade to 5.0. It start to fluctuate the signal...
Note: v1 and v2 are versions in matter of security of the EFS folder...
That is how this how begins...
Did you restore the original version 2 efs? Do you have a backup of the original efs? If not, I'm not sure if an nvwriter will help.
I think I do not have one...
What should I do?.....
I'm not sure what to suggest. Maybe Google nvwriter and see if it works with your phone.

Lost my IMEI, IMEI 0000000000 and i did not backup EFS folder. GS4 SHV-E300K Korean

okay so i tried to install xposed framework via recovery since it gave me an error during normal install, the device rebooted the got stuck in a bootloop, i flashed the latest rom for the shv-e300k from sammobile, everything worked great and the device booted into touchwiz, but there was 'No service' and the phone didnt connect to mobile network, when i dial *#06# i get IMEI 0000000000000.
i tried flashing different stock and custom roms, but nothing worked.. i tried a method to restore imei by copying EFS folder and using the .nvdata file, problem is there is not .nvdata in my EFS folder, I even tried installing cyanogenmod 13 and installing xposed framework on it together with the IMEI changer module, I typed my IMEI there but still no service..
PLEASE HELP!!!!!
The NV Data no longer lives in the EFS folder but is located in a hidden partition you cannot access. Wanam Partition Backup could have backed up and restored that partition for you if you had used it, but since you didn't, you'll have to take the phone to a service center and have the service center restore the IMEI.

can you please tell me how to get to that partition using wanam partition backup ? and what is the partiton called ?
All the app does is back up and restore that partition. It doesn't let you access that partition, and besides, it's too late anyway. Your IMEI is gone, and using the app now would only back up what you currently have.
This device needs to be taken to the service center.
same problem here

respected dev. i have the same problem. i flash a different firmware and now my phone baseband is unknown and imei is null. after a few days of checking its still not working. i have recovered its last working condition details as you can see in the photo attached
If restoring stock firmware does not restore the imei, you will probably have to have it fixed by jtag service or repaired using a programming box like an octopus box: http://octopusbox.com
Or have the phone serviced by Samsung, as discussing tools to rewrite IMEI I don't think is permitted on XDA.
I think discussions about restoring the original imei to the original motherboard/phone is okay but discussion about changing imei or serial number to something other than the original is not permitted.
Could you please check this.

check this but before this i want to ask that can i flash other firmware so that i can get baseband back. if i get baseband then i will use the above software to install the New Imei on the Phone. Tomorrow i will try every possible method to get back the phone to life and then if i fail, i will take it to the service center but if there is any possible way that you can help us so please assist and we will appreciate your assistance. thanks Regard Muhammad Ismail
That Xposed module won't work as what it does is spoof the IMEI for apps that have reading or sending the IMEI in their permissions. It does not change the existing IMEI and cannot be used to restore a lost IMEI. It requires the Xposed framework to function in the first place, which should give you a really big clue that this won't work.
If you want to waste the time and try it I'm not going to stop you, but the resolution to the problem requires tools only Samsung has. Android can't rewrite the IMEI as the IMEI is part of the phone's low-level firmware that Android cannot touch.
check your phone box if you have lost the imei

IMEI Writing I9500

Yesterday I decided to Upgrade my S4 i9500 to 6.0, the rom is amazing (despite the amount of battery it consumes) but when trying to acces to the imei (*#06#) it shows 0049990106..... as you might notice not my imei, I did this EFS.img backup, via terminal but now I am not able to restore it via terminal, I rooted the phone but I just can't do it. i wonder If i can Write the imei via PC or APK since i have it wrote down in my phone bill but obviously now the warranty is totally void... so I have the efs but I can't restore it (it shows succed restoration but nothing happens, no imei change) and i have the IMEI number and i really need help what can I do?
If it were that simple to change the IMEI, then anyone could just borrow a phone from somebody, get the IMEI, and do some mischief with that IMEI.
Did you restore the imei to a stock ROM?

Take the device to a service center and have them fix it. You backed up the EFS partition, but nv_data, which contains the IMEI, is no longer stored there. Thus the IMEI was not backed up, which is why you can't restore it.
