Hi,
you are the first person who mentioned this problem.
In usual cases, this is working fine.
How was it before you've installed LOS16?
Is there general a mounting problem with EFS?
Is your baseband working or unknown?
It works sir, even sim detection started working, but no signal at all, i assumed so because i saw some threads about using sim, and bugs with phone calls.

Does it work with stock rom?
The most important thing, dont wipe or format efs!
This will destroy your imei data.

Never wiped the efs, i got the note as a christmas gift from an aunt, it wouldnt boot up, checked stock recovery, it said "failed to mount efs (invalid argument)" i didnt know any thing about that, so i thought flashing stock rom would fix it, it didn't. One way or another i finally got it to boot, but it displayed a transparent window with yellow letters on the home screen. If i left the home screen, the window disappeared. So i decided to switch to custom rom, but anytime i enter twrp, i still get the efs not mounted error, i usually mount it manually to stop the error from showing, i still have imei so i'm not sure the efs is corrupt.

Ok this doesnt sound so bad, if the shown imei is yours (and not a 0049****** IMEI),
you just have to disable factory mode and your sim card detection should be back.
But TWRP should be able to mount it!
I'm pretty sure, that I could fix your problem (build some things years ago to fix a corrupt efs dumps, withoult loosing the imei and certificate).

You flashed the full Google factory image (flash-all.batt) in fastboot and your issue still not solved? Do you see a Imei number when you type in dialpad *#06# and a Macadress in about the phone? Have you backed-up your EFS folder? Start with flashing the cache.img in fastboot (fastboot flash cache cache.img), that helps sometimes.
already done

Well, imo the EFS file is corrupted, you will need a new motherboard to fix the issue i`am afraid. Sorry mate, hope i`am wrong and maybe someone else has a different opinion that can help you
these are the exact symptoms of a corrupt EFS, and because you don't have a backup your phone is screwed and you will need a new motherboard. always backup EFS the moment you get your phone... That's what everybody says.
If I were you in this situation I'd salvage as many sellable parts of the phone (screen, battery etc), and use the money to buy a completely new phone. Otherwise I will just send it in for replacement

don't think efs messed up
I don't think that the efs is messed up.I only did a restore from backup.moreover I had never flashed any custom ROM on the device.I was running stock ROM with xposed and restored stock ROM.Also,the day this thing happened,I flashed factory image several times and was unable to fix the problem.However,the next day it became fine automatically and was showing baseband and imei.Then I just power off the phone.When I turned it on,I was again not able to see imei.Since then I have been unable to get imei back.
Hi,
I've a Nexus 5 (D821) and I was under Slimkat (4.4.4) since a long time with no problems.
One day, the phone lost the network, and impossible to see the internal storage (I've lost all my pictures...)
I look into IMEI (I allready had this problem with my NOTE 3), and saw that there wasn't IMEI....
Ok. I've a backup of IMEI with TWRP and nandroid backup. I try to restore, but no-way, still the same problem. In TWRP, with mtp, I can see the internal storage, and done a backup of my pictures.
I tried to upgrade to 5.1.0 with factory image, i flashed all step by step manually, but the phone doesn't boot...
I try to relock, unlock the bootloader. Impossible to boot.
With my old Note 3, I solved the problem when i only erased the EFS folder. It was rebuilt at the next boot, and problem was solved. But I didn't saw EFS folder on Hammerhead, or, I don't know where it is...
In TWRP, when I flash something, it said "unable to mount /persist" no problem with other partition.
Any idea? Sorry for my language...

Great!!!
Thank you very mutch! I'll try this evening!
Perfect! I recover my phone.
Thank you very mutch !!!
So I had a custom rom on my phone and it went in to a boot loop and after messing about I wiped the wrong partition and now have no IMEI on the phone. Worse still cant find the back up of the phone so unable to restore. Its ok as I have a second Mi4c with sMiUI on and working flawlessly but I would like to recover the non working one. I still have the IMEI, SN etc on the box but need a way to get it back on to the phone.
The phone is not bricked, I have sMiUI back on and can flash back to MIUI if needed but the phone works just no IMEI so unable to connect to the network.
So after a lot of googling and translating Russian and Chinese posts it seems my best option is QPST however I cant seem to find a diag driver for this phone. So QPST isnt recognising my phone.
I dial *#*#717717#*#* to enter diag mode, run device manager and see my phone showing that there is issues as no driver for this mode. I tried the Mi2 diag driver in the hope it would be compatible but it doesnt seem to be.
So now Im at a wall that I cant seem to get over and was wondering if there was anything else I am missing. A fresh pair of eyes is needed as I have flipped through so many browser tabs. Maybe I have missed the correct driver or another route is needed.
Any help is appreciated.

Thanks for replying. Its a Qualcomm Snapdragon 808 hexa-core 1.8GHz
Maybe you can find it here :

But putting it back on your phone is an other thing...
---------- Post added at 11:26 AM ---------- Previous post was at 11:19 AM ----------
For putting a french IMEI, I saw this :
with terminal emulator try :
echo ‘AT+EGMR=1,7,”IMEI_1″‘ >/dev/pttycmd1
echo ‘AT+EGMR=1,10,”IMEI_2″‘ >/dev/pttycmd1
If you have a $
It did something
On the tutorial I saw, reinitialisating should recreate an IMEI.
It's weired but it's something I saw there :
http://www.android-mt.com/tutoriel/hackzone-changez-numero-imei-16379
No guarantee it will works...
What did you use to wipe the wrong partition?
Can't you flash miui ROM with their recovery tool?
Cool ill check out those links now.
I wiped with TWRP as formatted and cleared the entire phone. Im in Beijing and theres a Xiaomi store I may end up taking it to if I dont get any further and see what they can do.
Didn't know twrp had such a dangerous setting that wipes the imei

There's no such option to clear the entire phone in the wipe menu of twrp. It's dalvik cache, system, data, internal storage, cache and USB.
What did you do to have imei removed?!?!
As stated in the quote you posted I formatted the phone. I wiped first when I first flashed the rom and the phone worked fine. I changed the phones band in the phone settings and it went in to a boot loop and wiping wouldnt fix, flashing wouldnt fix so I first formatted it again didnt fix so I then MiFlashed and it was working but with no IMEI. Although it could have been changing the band that corrupted the IMEI now thinking of it I assumed it was the format that removed the partition with IMEI. Regardless though the phone now has no IMEI. I have another Mi4c working fine with SMIUI so its in no rush to fix this broken one and since it doesnt look like its possible publicly Ill have to get in contact with Xiaomi at some point.
Can't you change the band again?

I don't understand you saying "I formatted the phone." Meaning you wiped dalvik cache, system, data, internal storage and cache? None of those partitions have anything to do with IMEI. You might have flashed a mal ROM with MiFlash??

Hey guys,
and thank you in advance for helping me!
Well, yesterday I wanted to install the latest Lineage OS on my S7. As usually I installed TWPR (latest version) first, put the Lineage image on the SD Card and flashed it. However sth went wrong and my "data" partition was wiped as well... Now ithe phone was only booting into the TWPR Bootscreen. Nothing else happend. So I thought i messed it up.
So i formated everything possible into "EXT 4". Finally I could run TWPR again and also install the Lineage OS. So far so good... However now my Sim Card is not detected. I tried to reinstall the Lineage OS serveral times - the issue stays the same!
I used latest Odin3 on a Win 10 machine to install the TWPR...
My provider is 1&1 if that matters.
Can anyone please help me? Because I just called a Samsung certified reseller and they told me, that the only chance is to install a new motherboard, which will cost around 300€!!!!! Thats not an option, when u take a look at the prices right now for a new S7
Thank u sooo much!
Have you also formated your EFS partition? Your IMEI is stored into this partition and without IMEI the phone cannot log in into a mobile network.
If you have a backup of your EFS partition, restore this, and the SIM should work fine.

Hey,
I have the same issue today, how can I get EFS partition if for some reason I have lost it?
I still have phones imey at the back of the phone though.
Just male a backup of the EFS and store it at a save place (PC/Cloud). If the IMEI on the phone wont work, just copy it back from the PC to the Phone
Hello guys,
So i have experienced alot of efs problems in the past and i managed to fix them all but now i can't really do anything about it, i tried flashing the combination firmware i flashed the correct file (i flashed U3) but i keep getting an bootloader exception error, so i went back to stock and tried again, got bootloader exception error again, now i am back at stock and i have no idea what to do i asked a repair center and he said 60€ i am not paying 60€ for a stupid code that turned in to 000000000000000 my baseband is NOT unknown and my signal bar keeps changing beween no signal and the normal signal bar it i have never experienced a changing signal bar like that before i hope someone can help me with this because i can't make any phone calls since 2 weeks or more
Thank alot guys, and sorry for my bad english, english is not my main language
go and pay 60€, u can't back the original IMEI only with soft, u need a box to repair

any other solutions?
I already tried flashing the combination rom with odin v3.11.1 and i selected auto reboot, re-partition, nand erease all, f.reset time, efs clear and bootloader update also no luck, i clicked on ime and entered *#06# to see or i got my imei back and nope i also wiped my full efs before flashing the rom, this problem sounds more serious then i've ever thought it would be
it would be great to have some idea's to fix this...
last time when i had this problem on my phone i wiped my full efs and installed sac23's s9 port rom suprisingly it did help me bring back my imei now i did that again and no luck, the problem also is that i used twrp to delete my efs now twrp doesnt recognize my efs so it shows that my /efs is empty and root explorer says that it has files in it i need to wipe efs with twrp like i did before because if i delete it while i have my phone on it gets rebuilded again? files keep coming back but my imei, signal are not coming back its weird, i tried samsung kies and smart switch but it says SM-G935F not supported
the combination rom also keeps getting cp crash error, it so after a short moment in the combination rom it reboots in cp crash mode or something like that with green and red text
UPDATE: IMEI is NOT 0 anymore, but its not correct, the imeisv numer is now at the end of the imei number which means its now a 16 number imei, it also says simcard not provisionized please help me guys
UPDATE: [SOLVED] I can use my phone 100% again,
I fixed it I accidentally switched my simcard to a simcard that was suspended,
Now for the people also have problems,
1. Go to twrp
2. Make sure Efs has been checked at mount
3. Go to file manager
4. Go to /efs and delete everything in it (DO NOT DELETE /EFS IT SELF OR ELSE PHONE WONT BOOT!! ONLY DELETE WHATS IN IT)
5. now flash a new rom directly without restarting your phone after deleting whats in your efs or else your efs will rebuild, now it should work, if your imei is changed and it says sim not provisoned then just change your simcard because that error message means you have been suspended or your sim is inactive

So basically I can flash any Oreo custom rom and the EFS would repair ?
I have the Z3X box and I tried to repair the IMEI by entering my IMEI but unfortunately I made a 1 digit mistake.
The IMEI was written ok but did not Patch the certificate, at the time was on Binary 2, the phone got automatically update with latest stock (Binary 5), now can't repair IMEI nor patch the certificate (it would require downgrade to 7.0 which is not possible with Binary 3+).
Any idea ?

Nope, after erasing the efs content, I flashed custom rom and gapps, then rebooted but got stuck, so I went back in TWRP, erased cache/dalvik, check efs directory and all the files where rebuilt.
