Imei lost, wifi doesn't turn on after the new ota update for oneplus 5t - OnePlus 5T Questions & Answers

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.).

I found that many of them suggests to write IMEI number using QPST or IMEI writer. Can we go for that method for restoring it. I have both the IMEI numbers with me(on the box). Can u help me with it. plz

Your best bet is to contact OnePlus and see if they can restore it for you.

T-mobile S4 Stock Android 4.3, Cannot Unlock, IMEI unknown after attempt by localshop

Hi All,
I had purchased T-Mobile Samsung Galaxy S4 (SGH-M919) with Stock android 4.3 while I was in usa, and want to use it in my home country now as I have left usa. I couldn't found any unlock solution on internet for stock android 4.3, and T-Mobile would not give me the unlock code. I tried third party services to provide unlock code and it did not work either. So I went to a local shop, and he screwed everything up. When I went back to the local shop to receive my phone (hoping it might have been definitely unlocked by them), he told me that he tried to downgrade it to 4.2.2 but it did not work (only after reading through all the forums I realize there is no way to go back to stock 4.2.2 if you are on stock 4.3 because of knox / bootloader issues on 4.3, leads me to think the shopowner did not really do his research before touching my phone, and no, he did not do any EFS backup). In an attempt to unlock my phone, he also flashed Metro PCS stock ROM on my phone, not to mention, my IMEI number is also 'Unknown' now. I managed to get back on T-Mobile stock 4.3 ROM now but still IMEI is unknown. I also tried to go to nearest Samsung center and they said they would not touch international phone models. At this point I have no idea what to do. Any suggestions how to get back my IMEI and or at the least to get the phone working to my country's network?
Thanks.
Try flashing the mk2 modem using odin. That may work but not sure.

The local shop broke it. Tell them to pay for it.
Also, the only reason T Mobile won't give you an unlock code is if the phone isn't paid for in full. If the phone is paid for in full, they HAVE to give you the unlock code.
Are you sure you didn't buy the phone in the US, then leave the country without paying the bill so you could use the phone internationally without paying full price? If not, there is no reason T Mobile wouldn't give you the unlock code. So there's some missing information in this story.
Also, we do not discuss how to change IMEI's on XDA. The only thing permissable on XDA about flashing IMEI's is restoring YOUR OWN IMEI from a backup. That is done by restoring the EFS partition. But you didn't have a back up so you can't do that. That means anyway to fix your IMEI involves what is an illegal hack and that discussion is expressly not permitted on XDA. That information is used for illegal purposes and XDA is not going to be the place where it's shared for legal reasons.

Hi skipjacks, thanks for responding. Nothing is pending with t-mobile, I was on prepaid account. I bought the phone like 10 days before leaving usa (due to emergency). T-mobile says my number on this new device should have being working for at least 45 days or so with refill balance. My cycle ended after 15 days of purchase and I really didnt see any reason to refill it as I was no more in usa. And no, I dont want to CHANGE my IMEI, only want to restore my own IMEI only. I am not sure if my EFS partition is corrupted, because I rooted my phone tried to backup EFS folder now (I know its too late but still), deleted it and rebooted (as a few threads suggested it would regenerate nv data files), but neither did I see any nv files when I did a back up now, nor after I rebooted. When I rebooted, the EFS folder did regenerate but there were no nv files in there. Also, after deleting EFS and regeneration the serial number was corrupted, but when I restored my backup, the serial number showed up correctly again. Also my current backup contains the imei folder with mps.code_bat file. I noticed that even imei folder was not regenerated on deletion of EFS and reboot. I somehow have the feeling that this is still indicating that my original EFS folder is still present (though I may be wrong, because I dont know). But my concern is the nv data files, which I dont see anywhere. I did come across several threads about imei corruption and restoration, but the only one I didnt come across was T-mobile SGH-M919 with stock android 4.3. I am wondering if this has some different file storage structure for imei (which again I dont know). At this point I am concerned about getting back my imei, I can get the unlock code from some reputed paid service again. I understand that open discussion about imei involving anything CHANGING IMEI is not allowed here. If anyone could just help me out restoring my original imei, even by pm, I would really appreciate it. I just dont want to throw away the phone and lose my money because of the error done by repair shop.

First off....the enter key is your friend. Hit it every so often when typing giant blocks of text like that. :laugh:
Second, since your IMEI has been deleted, you now have to change it, even if you just want to change it back to what it was before. The process to fix it now is what can't be discussed here.
IF you had backed up your EFS partition, then it would be as simple as restoring it in recovery. That's all well and good. But your IMEI is now 0, so you have to change it to what it was.
But all that aside, you went to a store and they broke it. Take it back there and raise holy hell until they fix it for you or buy you a new one. I know consumer protections are stronger in some countries than others, but wherever you are, yelling and screaming is a universal language.

Can someone at least tell me what file in T-Mobile Galaxy S4 SGH-M919 Stock Android 4.3 contains imei number, so at least I know if I even have that file or not or whether it is missing? Thanks.

Whether your file is missing, modified, or corrupted, you need your /efs folder to restore it. You do not have have a nandroid backup or the /efs folder. I am sorry but the simplest we can put it without sounding harsh, you're screwed. You need to request the local shop give you a replacement phone or credit to get a new one.
Update: I went back to the shop and told them "You broke it, you fix it, I don't know how and I don't care, you gotta fix it". They managed to fix the imei number somehow. Regarding unlock, the shop ended buying the unlock code themselves. They mentioned that no one is able to unlock T-Mobile S4 with Stock 4.3 as of now without unlock code, unless they have some device like Z3x box. The phone is finally unlocked and working fine on my network. (YES, A HUGE HUGE RELIEF).
Everything is fine, except for 2 issues.
1. I want to backup my EFS folder so that I don't enter into trouble with IMEI again. I tried EFS Pro, but its not working. All I see is "'Initializing ADB server..." (the phone is rooted, usb debugging mode enabled, and supersu permission granted when prompted). I also tried to backup using Andromizer, but it says "Notification: File not found in /storage/emulated/0/Amdromizer/efs/efs.img". What is my best option as of now to backup and store my imei safely somewhere?
2. I am having issues with Wi-Fi. Before the shop flashed my phone, it was all good, but now it doesn't auto-connect to my home Wi-Fi anymore. Everytime I reboot or get out of range, I have to manually select my home network everytime and also enter the password everytime. Nothing has changed on my router. The other Samsung device that I have still auto-connects to my home Wi-Fi as usual. How can I fix this?
Thanks.

For the efs you can back it up using recovery. Just boot to recovery and its one of the options in the backup menu. The resulting file will be like a few KB. Its supposed to be small. Dont worry

Don't root lg g3 855

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.

IMEI lost, questions about backing up another MOTO Z Play "EFS".

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.

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..

Honor 7x volte problem.

I am in a very big problem.
Read carefully if you want to help me.
I rooted my honor 7x for trying the aosp 8.0 oreo rom i found that rom very intresting and very awesome i cant complain as it was its initial stage.
But then i moved to the official firmware of honor 7x but after flashing that from pc many functions got extinct...
Like-no volte
No update app
No system files app
And many other apps
Though i am okay with the app but cant live without volte if there is someone who knows the solution please help me.
Thanx in advance
My phone number- MOD EDIT: I removed your phone number. It's a bad idea to give away your phone number on a public forum with over 8 million members.
Did you flash original firmware? Has your build number changed?

Did you go back to the exact same firmware?
What is the buildnumber before and after, is it the same?
How did you go back to stock?
Because I was in the same position and tried flashing some dts.img etc. image files from some other variant and completely bricked the phone. Had to take it to service centre and replace motherboard. Only then they could flash stock rom.
Yes the build number have changed
I searched the whole internet but i cant find one so flashed some other like same firmware but as i told the features were missing. Can you tell how much they costed you to replace the motherboard...thanx for replying.

Oh my God! the world is round! I was in the exact same position yesterday as you are now! Only blunder I did was to flash some more img files and totally brick the phone. You still have hope as you asked for help before trying anything stupid!
You can directly go to service centre and get it flashed without any motherboard replacement. They should be able to power the phone up, that is all. Mine was totally dead.
By the way, mine was under warranty and there were not many technical people at the front desk of the service centre. So I did not have to lie and did not mention unlocked boot loader etc. Just told them I tried to flash a software update of different variant and that bricked the phone (which is true). So they changed the motherboard for free! didn't take a single penny.

No IMEI, IMEI SV, or Signal after flash rom stock

First of all, i started being a newbie, i just wanted to install magisk for cam2api, but i messed up: i combined for error 2 different system (mine that was ios9 and ios8). So i tried to read more and more threads and it just got worse. to make the story short: i had to get to test-point and restore the phone with Xiaomi Mi Flash tool & an original rom stock.
So now that i can go inside the Android System and use the phone, my sim card is just not working, i checked and my imei was 0 and my IMEI SV also 0.
I tried deleting modemst 1 and 2, i tried to reflash the phone with another stock images, updating the phone via android (normal way), i tried to restore my imei with the QPST Dual Imei (and it worked but the IMEI SV still in 0). nothing is working Please i need help i think my efs folder it's corrupted but i'm not shure.
Also i don't have any EFS backup or System backup, nothing.

I´m not sure what you mean by ios8 and ios9, maybe oreo and pie.
For the next time just so you know test point method is not recommended while you are not completely bricked (although is recommended out there without care), on a unlocked device most probably you won´t need it to solve this kind of issue, there are other resources to try previous to this stage.
I never had this kind of problem, you might try this https://zfirmware.com/how-to-repair-qualcomm-imei-via-qualcomm-write-imei-tool/

If everything fails and your knowledge is not helping you to find a solution and you are still under warranty and respect the warranty for physical aspect of the device (no scuffs, no damage, no aftermarket replaced parts that may damaged warranty voids inside the phone) you can flash it stock, lock bootloader and file a warranty replacement as "damage from OTA". The service will replace your motherboard.
I need help

I knew that there is a method to restore IMEIs via adb but I don´t remember commands so I never need it. First I do before tinkering device is to backup IMEI/EFS/NVram.
I had a theory that years ago I proved, IMEI is not really lost but just overlapped so if you have some friend that can give you their backup this will recover the yours but won´t overwrite/replace the yours. Not sure if it works yet.
About the tool that I linked maybe you need to get it through either in fastboot or download mode, try both; I don´t think that detect it while device is on.
