[Q] Survived from brick but i ve lost my IMEI

I tried to install the new version of CyanogenMod Snapshop but unfortunately afte the reboot of my LG G2 D802 the mobile phone bricked.
I read a lot around the Internet and finaly i succeeded to unbrick it. Th problem now is that i do not have IMEI (is null now). I read that there is one program that you can fix your disappeared IMEI but cannot work in my personal laptop. Do you know anything how to repair and fix my IMEI with my previous official IMEI (i have it in the box that i bought but i didnt have any backup of it).
Thank you

I am having the same problem. I was loading a milestone version of a rom and when it loaded after wiping there was no service whatsoever and everything is null. I understand it wiped the efs and I dont have a backup. I also understand that we can change the info back with the numbers off of the original box using dfa cdma tools. I have the program but my question is the 000000 code does not work when i try to unlock the phone. Anyone with any experience with this program that can help me to re write my meid???

Which program do you have?

Dfs CDMA tools

I don't have any personal experience with this, but I have done a ton of reading on this problem and it's become my biggest fear. From what I have gathered you have very very little chance of fixing this yourself. It most cases it goes back to the manufacturer. Can you tell us exactly how this happen?

I have no idea, i have been rooted for months and swapped roms like crazy. I wiped and installed a new rom and then it was getting no service so i tried to update profile and said it couldnt. Then check in the settings for the baseband and meid and unknown was shown across the board. Trying to figure it all out now!

I have had the same thing happen what cm did u install I had a d802 version on my ls980 restored it but now it will only accept a d802 modem and the signal is weak and drops out but it did show my ESN and imei and baseband again instead of unknown if I would have flashed it with a ls980 modem

Have you tried restoring a backup?
Sent from my dr87 v7 powered, Mahdified LG G2 (D801)

My problem started when I tried to update my LG G2 D8002 to the latest Cyanogenmod Kitkat Snapshop and i stuck in clockworkmod recovery loop after returning in CWM to take backup. I tried to connect it to my Laptop but i cannot have any access in my files via my laptop. The bad thing that i did is that i formated everything in my mobile (as you can see and my IMEI too) to make a clear installation of a new rom after the brick. When i entered my new ROM i realized that i have everything apart from my IMEI. So that i do not have any network-signal in my mobile but a connection to Wifi
The program Dfs CDMA tools and Octopus Box does not work in my desktop. (Any idea?)
Do you have any idea how to repair it? I read that there is a folder (nfs i suppose that encode inside the IMEI). So, if someone find this folder can upload it somewhere? Probably will find a solution to solve it.

i was solved problem with no imei :
make full buckup from TWRC in another LS980
restored that buckup in bricked phone (make first buckup on it, to know name of folder, and take to that folder buckup from work phone)
sorry for me English

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.

You may have a defective modem, try installing new modem software and see if that works. good luck

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.

No, under absolutely no circumstances should anyone give to you their EFS information/backup. It's illegal for a start. You should have made a backup of your EFS, you're going to have to send it for repair.

^^This, exactly.

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

Galaxy A5 2017 SM-A520F - root/IMEI problem/question

Hello all,
Ok let me tell you what happened first.
In March I bought said phone on ebay from a guy which seemed a legit person, 150 or so reviews, a lot of stuff sold, positive reviews etc.
For the past 6 month everything worked fine and i used the phone in the UK on EE (phone is locked to EE) without problems.
on Saturday the phone suddenly has been not geting any signal so I did some invetigations and it turns out the guy who sold the phone is on contract with EE with the phone and did an insurance claim as lost or stolen.
So now the phone has been Blacklisted and i cant use it anymore, to make calls etc on any network.
I tried to get Info from |EE, Ebay etc but with no luck.
I did some research and found that i can change the IMEI number to make the phone work again.
So I must say first up that I dont have a clue from rooting or any modyfing stuff with phones apart from the normal ANdroid things.
So I did some research and after misserably failing to root the phone myself, I got a company "one click root" to succesfully got my phone rooted.
Now I tried the options to change the IMEI number but none of them works:
"ok i cant post outside links:
the 2 versions to change IMEI which i found and tried are : with xposed and imeichanger app, and also one where you have to dial a number which opens radio frequenzy and then another number where you can change IMEI number
this does not work because the xposed framework is not compatible with this phone (yet)
this does not work as i dont have signal and the "call" does not go through.
thats the only thing I found and i thought as a last resort I try my luck here if anyone knows of a different way tho change the IMEI number for this phone apart from the 2 options above before i go and spend another 350£ for a new phone (this time from a shop )
thanks in advance

Hi guys,
I have an issue with My SM-A520F. I bought it to a particular and according to the initial network provider, this person stop to pay his subscription.
So, I'm looking for solution to change IMEI for this model. I think the nv_data.bin is encrypted. Perhaps if I change the nv_data.bin(whith the corresponding nv_data.bin.md5) with another which not blocked in my country it will work. So, if someone want to exchange his nv_data.

Hi Xposed and IMEI changer will not help you. If you want I can explain you how to install it on this phone. But the IMEI changed by IMEI changer with xposed framwork is not the IMEI sent to the network provider. The IMEI changed by this app is used to mask your IMEI to the apps that track you by using the IMEI. So it's just a spoof of the IMEI for apps using IMEI and not a really IMEI change.

Backup the EFS with TWRP then delete the EFS folder. The EFS should rebuild and give a default IMEI when the devices reboots or try deleting NV_DATA.bin, NV_DATA.bin.md5, it should get replaced by NV_DATA.BAK.bin if it's any good.
You can also attempt to Format and remount the EFS partition. It works for some devices.
