Hi, I've been trying to find a solution for the problem of null IMEI I'm having after wiping EFS partition on the Chinese TWRP, maybe it's not that and it is because I've erased modemst1, modemst2 and flashed modem+fsg.
I'm pretty sure it had to do with one of those procedures, when I wiped the EFS I've got some error saying it couldn't be done but something went missing.
I've got a more direct question now, my brother just bought a Moto Z Play yesterday, if I backup his EFS on my phone (he already asked if I want to do that) will both of us would be able to use our phone normally?
can anyone backup their "efs" and upload it here so that i can restore it and get back my imei.
plzzz. needed indian efs

No way, like you already now, each phone has an individual IMEI. Your phone is unfortunately unusable.
What did you attempt to do? Flash another firmware package ?

Lenovo could generate it. But they probably instead replace the main board. You may ask them how much the repair is.
I think I'll just take it there and see if they can do anything about.
well, lesson learnt hard way

Now you know not to use fishy Chinese recoveries.

Hey you can use sigma box to restore imei which will cost you around 800 rs,same thing happened for me but still not fixed just using with wifi
If partition can be wiped, then is not read only. If is not read only, should be possible to write backup back. Otherwise, what's the point of the backup?!
Each phone should/must have different IMEI, depending of the network. In theory, should be possible to take partition from one phone and write to another. However, Moto maybe prevents that checking some hash, serial number... If it's possible to write partition from another phone, again question is can those two phones be on the same network in the same time. I also saw a way to change IMEI, I think even on this sub forum.
If someone solve this problem I definitive pay to that sir, he would be rich In the first day..

Hello, this is really weird. In fact, when I insert the SIM to my Note 2 N7100 and turn it on, it allows me to make emergency call, but I cannot use it to make any others and it doesn't show the carrier name (it shows Emergency call only). And when I try to use it to make normal phone calls, it says that I am not registered to a mobile network. I try to factory reset my phone, but the problem remains. I then try to remove the SIM card, and it says that I need to insert a SIM card (that means that it is not a hardware problem since it recognizes the card). I then try to go to the mobile network setting to try to connect to the network manually, it connects me but it shows me a warning which says that the mobile network service is not available (and the Emergency call only label remains). However, I am sure that this is not the problem of the card neither since when I insert the card to my Moto MB860, I can make calls as usual. So, what is the problem ??? It seems to me that the problem happens spontaneously since it works perfectly until yesterday. And all other wireless function works fine including wifi , Bluetooth and GPS and the only thing goes wrong is 3g and 2g.
Additional information:
ROM: Omega v.16
Carrier: Fido Canada (as you can see)
Thanks.
What comes to my mind at first that something wrong with your sim card but if you insist that everything is ok with your card so I don't know what to suggest to you. Is it not related with your Omega ROM?

Yes, I did downgrade from v17 back to 16 since something went wrong with Poweramp but I forgot that if I selected for the efs backup or not since I (stupidly) didn't think that efs is important...:banghead:

Do some basic troubleshooting:
Does the IMEI number from dialling *#06# match the one on the sticker?
If the answer to this is yes: Then you should contact your carrier as it sounds like your IMEI might have been blacklisted (often if a phone is reported stolen)
If the answer is no: Then you need to fix your IMEI so it matches as it should. This would usually be done by restoring your EFS backup. I suggest restoring a totally stock Firmware if they don't match and you don't have an EFS backup. But you should have one somewhere, surely? Every tutorial out there tells you to back it up...
Good luck.

Thanks for replying, I should have a backup, but it probably be the wrong one. Anyway I will go for a full stock restore since I have the firmware with me now.

Do you mean the one in the About Device ==> Status? In fact, the IMEI from the dialing does match the one in About Device ==> Status. However, I don't get your instruction since if in the case where IMEI from the setting matches the one on the dialer means that my phone is reported to be stolen, then why I have to make the IMEI in the setting and the one shown in the dialer the same?

No, when I say "The one on the sticker" I, strangely enough, mean the one on the sticker.
Take off your battery and the phone will have a sticker/label with the IMEI on it. Verify that number matches.

Thanks for your clearification No, it wasn't.:good: Then, I need to flash a stock firmware via Odin, right? In addition, when they say stock firmware, they mean the one that is on sammobile.com, right? In other words, if I have a Hong Kong version of GT-N7100, the file from this link (http://www.sammobile.com/firmwares/3/?download=15126) would be the correct one, isn't?

That's correct, yes. It doesn't actually matter which N7100 image you flash, but if you have a Hong Kong version you might as well flash that image. Just make sure you don't have a N7105 (the LTE/Dual Carrier version) - flashing A N7105 to an N7100 (or the other way around) is a recipe for major disaster.
Flashing the image should fix the problem, but it also depends. If the EFS is really totally corrupt, it won't help, you need to have that EFS backup or take the phone to someone who can repair it for you. There are specialist tools to repair EFS, but they cost quite a bit of money. Most reliable phone unlocking places should have something that can help you.
Anyway, hopefully restoring to stock will fix the problem.
Good luck.

Thanks for information, but how do I know that if the EFS is "totally" corrupt, "partially" corrupt, or not corrupt at all? In fact, I never touch the EFS in the root. Also, as I am not quite sure that if I have any previous EFS(S) backup or not, so, if possible, where does the backup(s) most likely to be found?
If you haven't taken an EFS backup yourself, then you won't have any.
I don't know the difference between corruption levels either, all I know is I've read a number of forum posts where someone has reflashed stock and their EFS data (i.e. the right IMEI number) is back. So I'd consider that to be a partial corruption. Others have flashed back to stock and it's still a bogus IMEI
Basically, flash back to stock. If it doesn't work, you'll have to take it in for repair.
UPDATE: Please read on - this information is incorrect - it is possible to recover with the correct modem flashed.
Before doing the flash with Odin, do I have to perform a factory reset? Since all the app data and homescreen layout remains the same after the reboot and the IMEI is also the same as before. And is it normal that my device got unrooted after flashing the stock firmware?
NOTE: The information from me in this post below is wrong

It's normal your device got unrooted, yes. If your IMEI is still the same after ODIN and stock flash, then you have major issues (sorry!)
Doing a factory reset etc won't help. Your /efs partition is either gone or corrupt.
What IMEI does *#06# show?

Just go through this thread http://forum.xda-developers.com/showthread.php?t=2333216
Even i had the same problem no network no imei nothing after downgrading so i just changed the modem and now everything is fine as it should be
Lost the imei tinkering.. Have no clue how but it is now missing from the settings and will not connect to the network. This is on my tmo g3. Please help
Dial *#06#
Nothing
What have you done to the phone?
Most of the time there is a sticker under the battery.
Yeah but what do i use to get the imei back inside the phone instead of just the sticker
Will donate if somebody can help me figure this out..
Isn't this that efs backup stuff talked about in the PurpleDrake thread?

As Skizzy034 noted you'll need to have performed an EFS backup. You can either flash the zips you made or use ADB to restore the partition.
Or call t mobile and tell em your phone does not work right and get replacement. You still never said what happened? What did you do right before issue happened?
I believe I saw a efs recovery method in the lg g2 forum but it looked like a long process and it might not even work for our phone. If I was you I would try to find it quick because normally anything that can potentially spoof imei numbers gets deleted when a moderator notices it.

That's of no help unless somebody comes out with a method for restoring without a backup (I've seen it done with a couple devices). Until that happens, unfortunately there's not a lot you can do with the device.
Do a search for a member by the name Odia, I messed mine up before on another phone and He helped me restore withbout any backup. This was before I ever heard of efs

What about if your phone has the WRONG imei number after flashing a ROM? Does that matter? The phone still works.
I don't have any info on being able to help but this is a prime example of why you take the few extra steps and back up. Most of the time I'll admit, in fact I have never needed mine but on those rare occasions its literally a phone saver.

Same happened to me! Did you fixed it or send it back for repair?
Editing the IMEI in any way is illegal and against our rules. The only allowed way is to have a backup. Anything else is not allowed here.
Also do not Suggest people send the device in to be repaired under warranty. This is Fraud and also not allowed.

I rooted my phone after 15 days the phone crashed with imei null error and i had to pay for motherboard replacement.
that is why every thread about rooting suggest to backup your efs partition.

Which method did you use to root?
Stumproot
If you had to pay for motherboard replacement, that means you wasnt able to turn the phone on? If its that, they couldnt prove your phone was rooted. If you were able to turn it on, you should simply flash stock and send it to repair center. So they wouldnt notice that phone was rooted. It is not for sure, that root your device made it to be imei NULL.

I have the similar problem as well, my phone couldn't switch on, and only stays at LG logo screen, and only can access fastboot mode.....
I didn't do the EFS back, so I'm planning to send it back to LG to change the motherboard.....
Or, is there any other way to fix it??
I really can't tell, sorry. About EFS, even if you could somehow establish communication between PC and G3 via adb you have to move those two files from SD in order to have them available after going back to stock.
My D850 has been rooted for 2 months my F400S was rooted until I dropped it and my F460S is also rooted. I've never had an issue with imei null error on any of my G3's. Did you do anything that could have caused this?
efs doesn't wipe by itself, if you have IMEI nul that means efs has been corrupted or deleted which is usually due to you doing a mod incorrectly. None of the current root methods will touch efs.

So as I though and I wrote before. Root is not failure for IMEI Null. So, he should just flash kdz to stock and turn it back. In that way he could say it happen by itself, thats it. No paying for new motherboard.

If you don't have EFS backup, no way of fixing that... You can try to reflash back to stock (that helped with corrupted EFS on my old Samsung) but there is a small chance for that to succeed.
First rule if you want to do anything with this phone is "always have a backup"...
I have found serious issues after new update in oneplus 5t. My IMEI number is null, both the sims are not detecting, wifi doesn't turn ON. This happened when after getting an OTA update in oneplus 5t. After flashing the file, the device works as normal for 2 days then suddenly restarted then the issue has found. I approached their service centre last week, they told that we need to change the motherboard for solving it. I found similar issues with other phones too and they have solutions with it. But can't find the solution for oneplus 5t.
I DIDNT HAVE ANY BACKUP DUE TO I AM UNAWARE OF IT. M REALLY SORRY FOR THAT.
Can anyone please help me out...I m sitting on it for the past 2 months can't find any solution...Please help me out
So the problem is that no one can restore your IMEIs - if there's no backup then you'll have to go for the mainboard replacement, there is no other way...
Thats hard, but I think thats how it is - always backup your EFS partiton, that should always be the first thing you do, if you want to modify anything (Root, etc.).
