They patched it in Jan. But effected users like us(who got effected on 2016) got proper fu***.
The result : NO SERVICE but detects sim card.
Kindly.....Plz....plz...plz....make a copy of your efs and provide it in this thread. Please also mention what factory image/build number u are using.
No one will give you his EFS backup because its unique for each phone..so you cant use someone else EFS on your phone...

Really?? Thats a big news for me its no problem do i know him or not.. How can you use someone else EFS/IMEI.. it would be 2 phones with same IMEI number..maybe it will work, but its like you use someone else ID card and present it like its yours..

Hey,
When the IMEI is corrupted on the software side, it still shows up using:
fastboot getvar all
So the IMEI is somehow corrupted on the EFS partition. How, I don't know. Seems like the EFS acts like a bridge between hardware/software. Of course, I could be wrong...
Some have tried but didn't succeed. Now, it's not the first time I see someone using another EFS backup and getting his IMEI back. I don't know why it would get "their"" original IMEI instead of the one included in the EFS backup either. But i guess they must all lie saying it fixed their device.
Cheers...
I have restored EFS using a backup from someone else's device EFS. It did not change my original imei.

Down do it. The efs is device dependent. It will contain things like your imei. So even if restored on another device it will end up causing issues due to the same imei on different devices. It can also make it so things like WiFi don't work

Okay thank you, I had no clue about efs so I'll take your word on it.
Guys can anyone share efs so that I can restore and save my phone..I Have no signal ispitevof detection sim card...it shows no service.. But when I use jio it shows full signal..kindly help..
I had similar problem with my OnePlus X. Apparently I was saving and restoring my efs partion with every twrp backup which eventually caused it to become currupt. Thought my phone was toast until a friend on telegram suggested deleting modem1 and modem2 files with adb commands. Sounded more destructive then good but it actually worked sim was reading again and got full use of my phone. It's good to make backup of efs but only once. Not sure if this is the fix for every phone but works with OnePlus and Xiaomi.
How to Fix EFS from Bootloader Mode using Fastboot commands
Setup ADB and Fastboot on your PC.
Enable Developer options & USB debugging on your Android device.
Connect your device to the PC and open a command window on the PC.
Issue the following commands one by one:
adb reboot bootloader
fastboot erase modemst1
fastboot erase modemst2
fastboot reboot

Hi
I don't know if you've fixed your issue with your g900v or not, but i have the same problem and the same phone and obviously the same symptoms ...
As far as I've tried, nothing worked not ODIN flashing ROMs, or QPST to write IMEI or EFS professtiona ADB .... etc.
What I've come to know is this :
1- keep the phone in a safe place till next months reveal a solution through developers here or elsewhere.
2- Flash the Original Samsung Verizon Rom ( Full Package with efs and bootloader mounts and all partitions " Clean Flash" ) which costs about 100$ .
3- Change the board for a (200$) new one .
So, I would try to pay the 100$ and flash the original ROM, and comeback to tell if it solved the Problem.
I wish if you share any different approach or feedback . I would love to hear it .
Bye
It could possibly be that your EFS folder is damaged. This is where your IMEI and Baseband info is stored. If that's the case for your device, these steps should work. I've done this on two phones (one being an S5) and it fixed this problem.
I'm assuming that you're rooted. If not then you'll need to root your device first. And you need to have debugging enabled. What this does is backups the files from the EFS folder, repairs the partition tables, then restores the files to the repaired folder.
1. Connect the phone to your computer. (Windows)
2. Download this: https://www.dropbox.com/s/v2h5dzisjd0rgj5/EFS_Professional_2.1.73_Release.zip?dl=0
3. Extract and run the program
4. Click EFS Professional... It will open a window showing that it found your phone
5. Click on the Backup Tab and make sure all of the partitions are checked, and your Device Filter is recognized
6. Hit the Backup button to backup the EFS folder
7. After that's done, click the Restore button and it will restore your files to the EFS folder.
I hope this helps you.
There used to be a tool for the Note 2 I believe, maybe S4, that would let you re-write your EFS if it accidentally got erased. Not a backup/restore deal, but a tool to key in your IMEI and it would write it to the phone. Maybe research that tool for a fix?

Was it a tool specifically for the Note 2, or multiple Samsung devices, or maybe a universal program like CDMA Workshop? I love that program. It's what I use when it comes to actually entirely rewriting files like this. Most of the time a full rewrite isn't needed though if the EFS folder has just been damaged. Which "damaged" is totally the wrong word here, but that's what it's called for some reason. I really don't even know how it happens, but I do know when it does, it usually just jumbles and/or fragments the info in the folder and needs to be put back in it's correct order. Kind of like defragging in Windows. Just a tool like you're talking about would definitely be cool for me to have though. I shall start my quest to find it. Lol
Please some help
Any luck yet ???
Got the same issue here, and none of the threads here worked .
Same problem
Hello,
I have the exact same problem. I bought the phone here in Mexico, and the phone came with erased EFS folder. Phone restarts automatically when screen turns off. When I'm using the phone, it works just fine, but some seconds after screen goes off, phone restarts automatically. EFS folder is messed up, I've tried out a lot EFS restoring tools with no luck.
I tried QPST but it does not detect the phone, only appears "?" and "No phone" blinking. The same happens with DFS Tool.
I will try to look for that tool joshw0000 talks about.
I hope we can find out a solution for this excellent phone.
Bye.
Hey ...
I did a factory reset and cache wipe, and now the phone stopped restarting when the screen goes off, but still got the "Unknown" issues.
But at least I got rid of the annoying restarts.
570 ppl read this and still no answer, I got to admit ... it's tough.

I was VERY stupid. I went back to stock Oxygen OS using a fastboot image and now if I dial #*06# the IMEI box shows up but no IMEI number is actually in the box it is just blank. I did post about this before but last time I didn't really know what happened I was asking if anyone could tell me what they thought happened. I am pretty sure I screwed up the EFS partition and I am just wondering what I need to do now. Is there some way I can repair it I mean I don't have a backup. Can I contact OnePlus support? I really need help.

This happened to me a few times in the past, all I had to do was wipe dalvik and cache again and it came back. Not sure if it's the same issue but I would give it a shot. Just boot into recovery and wipe them again and see if it gets you back up and running.

I cannot use that because my device is not hard bricked and it will not install the driver since I can enter the bootloader normally.
Not sure if you've seen this post its based on the post above but I think it just uses fastboot. Don't know if it will work for you, but figured it would be worth a shot.
http://forum.xda-developers.com/showpost.php?p=62973446&postcount=2
I tried using the tool and it did not work, I purposely hard bricked the device to try it and still no signal or imei. Another problem is WiFi takes about 4 minutes just to turn on but I can live with that I just want service.
Basically flashing back the stock should bring back the efs. Let's see if someone has a solution. Sorry!
EFS files are unique to each phone. If the EFS is corrupt or damaged, and there is no backup, I don't know of any way to fix it ;_; You can try OnePlus support but they aren't as dumb as carrier warranty or other phone manufacturers. They'll be more likely to know what you did.
It is possible to restore your imei number, I did it on my brothers lg g2. It requires some software for PC (I can't remember the name, you'll have to google it) and the box your phone came in with the imei number. It is possible, so don't lose hope!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Well, it seems like I have "No service" on my phone, and it says that my IMEI number is 0, and my IMEI/SV is 01. I tried flashing stock rom onto this when it happened. I can't afford a new one and the only way I can keep this phone is if I can fix it - is there any way I can make an IMEI then find the folder to put this back into my phone? I have no backup, but I do have a folder called GSII_repair and it has 2 files, efs_save.tar and efs_save.tar.gz, but I'm not sure it is of any use. I just recognized the efs as the efs folder. I can't find where my IMEI is at the moment, either, so I don't know whether it is completely deleted or just corrupted. I also have a Moto G 3rd gen, I may be able to get an IMEI file from that, and then change the hexadecimals to fit my phone's original IMEI which is on my box. So please tell me, am I completely runined, and my phone is destroyed, or is there a chance that I can fix it? Thanks for any replies. Guys please help me though, I need it!

`fastboot erase all` is the bane of Moto devices, once it has been done if you don't have a backup of the EFS partition to restore you are pretty much screwed and need to get it reflashed by Moto.
I know this might sound a bit weird, but can't he grab an efs partition from another pure with the efs zeroed out and then he can re edit with his imei?
IMEI
I do still have my IMEI on my box, I know what it is. Is anyone out there willing to help me by copying their efs partition and then setting the IMEI value to 0, so I can change it and then put it back into my phone? I don't know, but it might work.
Hello everybody,
What can I do if my Axon 7 has lost the IMEI by restoring a backup through TWRP? My baseband version is unrecognized.
I have tried to save on this thread the mobile phone, but the problem "IMEI Changer" does not recognize DIAG port.
Windows only shows:
Sry for my bad english. I use Google Translate.
I hate to say this, but you're out of luck. If you restored your EFS partition via a bad version of TWRP, you're stuck. Send it back to ZTE.

I encountered the exact issue you told me. I restored a TWRP backup that I had made through a faulty TWRP version and it made me lose my IMEI and baseband. Tried just about anything. Nothing worked.
Restored everything to stock, reflashed stock recovery and locked bootloader and sent it back. Got a new one, only had to pay the shipping costs of my device to Germany. I hope you're as lucky as I have been. Thumbs up.

Folks need to stop messing with the EFS partition. The only things you should be backing up with twrp is boot, system, and data. Nothing else.

Also, I've found this Qualcomm Driver to always work for me in the past. Surprising. It's the ONLY one that could help my device get detected by certain tools.
I uploaded it to my AFH for safekeeping: https://www.androidfilehost.com/?fid=817550096634746189
If you haven't tried any of this yet, just give it a whirl. I used the IMEI tool to rewrite my IMEI when I accidentally wiped it, and it was perfect.

No. The IMEI is unique for every device. So the backup of another 6T won't work. I'm afraid you'll have to get the motherboard replaced.
