Hello everyone, I have a problem with my device, after installing 8 android and returning back was gone, I tried to restore it via persist sdes on the forum by the instructions like it turned out but then got the update over the air and it again became zero but the link worked decided to restore it via pixel but even on the pixel it was 0 can I return native firmware with normal imei sorry for my English
I have the same issue. On pixel room after all the instructions, but still no imei. Even after erasing modemst1/2 in bootloader.
I don't know why so many people are trying to restore IMEI with persist instructions. It is not meant to do that, and is only necessary for those who lost volte after getting back
service. If you do not have service and an IMEI of 0, adding the persist folder to your EFS will just further corrupt it. No where in the original instructions for using persist did it say to use it to fix IMEI 0.

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

Hi,
I have Axon 7 mini B2017G and I have lost network signal.
This initially happened after updating firmware to EU (to get 7.1.1) I noticed sound not working. So I tried to root phone for TWRP and Lineage but that resulted in IMEI 0 for both IMEI's.
I have since restored both original IMEI but still cannot get signal for more than 30seconds after a full factory reset. Regardless of firmware, rooted or not rooted etc etc.
Seems I have lost important NV data while messing with Modems and restoring IMEI etc.
Can someone please do a full EDL backup with "Axon7_Mini_EDL_Tool" of All partitions (including modemst1, modemst2 fsg) so I can restore baseband configuration, modem partitions etc???
If that isn't an option for someone with the same phone as me, then can you please backup NV items as QCN file so I can try repair my network issue??
The idea i have is to restore ALL partitions from exact same model/version and then restore my original IMEI's in the hopes that I can once again register GSM network and use the phone.
Thank you
Sorted.

same happened to me after messing with network setting, SIM 1 now stuck on LTE mode only which has limited coverage in some areas. SIM 2 is working fine.
I read somewhere that if you downgrade to Marshmallow, it might solve your problem.
I don't know what to do :crying::crying::crying:
I somehow erased my IMEI (it shows 0 in Settings) after flashing custom ROMs. I have no way to restore it as I did not backup the efs partition and I can't find the box for the phone with the IMEI sticker on it. I wiped modemst1 and modemst2 but that didn't change anything. I still have service but I'm worried I might get into legal trouble for using a phone without an IMEI. I also can't send it to ZTE as I can't be without a phone for days/weeks. Should I keep the phone or get a new one?
Odd that you still have service... I would keep using it.
same thing here on two boards. no luck with service on either, though. (Tmobile) both have no imei, no serial. fortunately, i have another DD axon and 1 body to test and work on the two boards. the best theory i have is to use QPST to backup .qcn and restore it. i feel like imei and serial are stored in the qfuse system. i cannot, however find a detailed answer on how to do that aside from videos and posts here and there that claim CDMA workshop ($100) will fix/restore it. my belief is that there is a function within qpst and qfil to do this, but i cant get my handset booted and recognized in a mode that allows such. there is also the lack of detail on how to boot into diagnostic mode (which i thought was EDL, but that doesnt work). really, i wish someone from ZTE would just say here is the factory image file (not edl, the whole emmc flash file) and this is how you flash it. Wishful thinking, i know.
so in a strange twist of events, restoring my efs backup reflashing b35 edl, despite it breaking touch, wiping data and flashing b29 edl (which restored my touch) netted me my IMEI back. i dont know why, but it did. finally. month long task finally back.
@bkores did you figure it out?
EDIT: i finally restored mine. took updating to b35 and wiping internal to register again for some weird reason. but its back.
Hello!
It's Briefin here, [okay first a quick background of mine: I'm very familiar with Custom Roms/Recovery/Rooting/Kernel etc. And have been doing it since a long time. Never got any significant issue to write on XDA. So it's my first thread. ] Okay now the issue is I recently flashed the EFS Partition of an another device (A TWRP backup file). The device from where I got the backup file was of the same model as mine of course. So it should be okay I thought. But after that, my phone's network signal stopped working. Tried everything available on the web but nothing worked. My whole IMEI is just messed up. It's showing 0(Zero). So my question is, is there any way that I can rewrite my IMEI?
Device name: Asus Max Pro M2 (X01BD)
Thanks!
Need a proper EFS
Same problem occurred with me. Mobile networks not working. I am a newbie in this section (custom ROMs). So I need a proper EFS backup(if this works).Please help someone.
maybe you can try this one bro
Messed With IMEI while Enjoying flashing?
IMEI number is a personal identifier and if gets corrupted you can loose working of SIM in those phone. Why would it happen? 1. Probably you went High and cause your modem to get corrupted? 2. Or the Old way deleted/removed/ate away NV_RAM file...
