Need help to fix imei issue

In the beginning, i can use my note 3 n9005 SFR as usual. But once i tried flashing rom, it showed as error (fail) because I chose BL instead of AP. And i tried to fix it by follow the instructions as Mr. Firasusman suggest me as said in the this link http://forum.xda-developers.com/showthread.php?t=2614787. It solved the problem my phone can now get into the normal screen but i found a new problem. I put in sim card but there is no network signal and I also lost imei when i checked in phone status. What should I do to fix this problem? Anyone, please help me. Thanks a lot.

Check whether EFS folder is backed up by flashed rom in sdcard. If your lucky you can use backup file to get imei number back. Few posts also suggest that flashing back stock rom also get back imei. I am not sure of it. Better back up efs to your pc.

Please suggest.

EFS is a folder in phone's file system which saves your phone model, IMEI number and lot more details, Important folder. Flashing ROM the efs folder got corrupted causing the loss of imei number. Try "radicalisto" reply and update the issue.

This fix never worked? - hmm,you have lost your EFS/IMEI somehow then. Does *#06# bring up an IMEI? - if not you'll have to search around for how to fix your IMEI (It can be done)

still need help here.

I bet you have not tried to flash a compatible custom kernel.
If your phone is an N9005 then flash this kernel below:
http://whatever.host-base.de/kernel/hlte/custom-n3-clean-0.98-eur.zip
If all else fails, why not flash a non-experimental Kitkat 4.4.2
TW based full feature custom rom. (There are so many good ones)
Good luck!

Hello, thankyou for your reply
yes i have a n9005
i did try to flash that kernel, then rebooted. same problem.
really not sure what to do, im really lost :crying:

HI, in dialer if you wite this code *#06# have you the same IMEI write behind your battery ?
have you make backup before ?

I experienced the exact same problem.
1. settings > about phone > status
Do you still have an IMEI listed? If yes, we must first backup your EFS, FSG, FSC partitions. Use EFSBackup tool from this thread and save backup somewhere securely.
2. Flash back to stock
If you were still on 4.3 flash 4.3 in order to keep the unlocked bootloader. Else flash 4.4 stock. Only flash the correct firmware from this list. You can figure out which device you have by using the Device Info feature of EFSBackup
This fixed the problem for me. Do not flash anything BEFORE making a backup of EFS, FSC, and FSC partitions. If you lose those you lose your IMEI, in that case it's pretty much finished.
Report back here with progress.

OK I understand you still have IMEI?
Do not flash anything at the moment. We MUST first backup efs, fsc, and fsg blocks.
If the phone was only on 4.3 stock when you bought and and you have only flashed CM on it the bootloader is still 4.3
The bootloader is only upgraded when you flash 4.4 kitkat STOCK ROM. CM does not touch your bootloader.
What is the problem with EFSBackup? Did you enable root access for apps AND adb in the developer options menu?
I say again do not flash anything before we can get these backups. We can still fix the phone ATM.

Thankyou for trying to help me.

When i connect my phone to the computer, computer detects it.

I am not sure how to enable root access for apps AND adb, im sorry. how do i do that ?

Assuming you have CM running do this:
Settings > About Phone > Build Number.
Tap the Build Number section 7 times in a row. A small message will pop up that says "You are now a developer".
Return to the settings menu. You will now see there's a new menu at the bottom called "Developer options". Enter that menu and scroll down to the section "DEBUGGING". Tap on "USB debugging" to enable it. A small window will pop up that asks you again if you want to enable debugging. Tap "OK".
If the phone was not yet connected with a USB cable to your computer do that now. After a few seconds a window will appear that display your computers authentication ID. It will ask you to allow access for that computer ID. Check the box that says something like "Do not ask again for this computer" and then tap "Allow" or "OK" (can't remember what it says).
Now scroll up a little bit in the Developer options menu until you see "Root access". It should currently say only "Apps". Tap the menu and select "Apps and ADB" from the popup.
When all that is done start EFSBackup again. It auto-detects if you did everything correctly as written here. Report back here with your progress.

Thankyou for helping me, i got through it, but now in EFS Professional i get this error

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.

If is not hardware, chances are that the efs folder is corrupted.
Try a different kernel
Try a different modem
Flash full wipe custom rom again..
Last flash stock rom...
If all fails the problem most like it is in the efs folder, if you have a backup restore it

Sent from my Nexus 7 using XDA Premium 4 mobile app

same issue.
I have the same issue as described by the op.
I flashed back to official 4.4.2 and the problem persist.
IMEI number is correct.
IMEISV is 01
Ive been trying to fix this for over a week to no avail. Losing my mind. Is there anything else you can suggest to fix this issue?
Phone is an i9500.

Was really hoping for some help by now. This will be the second time ive posted to this site in the 2 years ive been here with zero responses.
As a side note. I wanted to add that at the same time i started having the "not registered on network" error my sd card stopped being read by the phone also. I replaced the sim/sd holder in the phone itself hoping this would fix both issues but it has obviously not. Still not reading the sd. Says its blank or unrecognized file system. When i try to format it it doesn nothing. This is the sd I had in the phone before having issues. It worked fine then.
The phone just suddenly stopped working one morning. I used it to send a couple text and make a call, next time i picked it up "not registered" issue began. No changes to the phone in between those times.
I figured I would add this info in hopes of gaining a response.
Thanks.

[STEPS] How to Recover from bad IMEI

My problems starts after i flash SlimSaber over the Oxygen OS
Somehow it erase the EFS
Download the package here https://mega.co.nz/#!c0c1lZ7L!ADILW66W-aG0TNcuDzLd13pK6hjcq7omJhPxMiXUjZo
My case : NO WIFI, NO IMEI, AND NO SIGNAL. And on CM11S (install it via fastboot), and rooted + supersu
I did erase the modemst1, modemst2 and the persist. But still it didn't fix it
And i did try to run some command in the TWRP's terminal, but still not fix
What i did :
1. Download the packages
2. Open CMD and type : (Your phone is still on, and on the homescreen)
adb shell
su
setprop sys.usb.config diag,adb
3. Go to Device Manager, and see A0001 on the Other Devices
4. Right click on it and select Update Driver --> Browse blablabla --> Let me pick blablabla --> Show all devices and next --> Have Disk --> Browse --> Now, go to the downloaded Packages, and see Driver --> Select your OS (Win x64 or x86), in my case it's Win x64. Select Select and Install it anyway
5. Now, you'll see it named HTC Modem, now right click on it, but i forgot which tab that i click to see the COMx part..
6. Now, go to QPST folder, and rename QPST 2.7.411.msi to QPST.2.7.411.msi. And now, open Setup.exe
7. Go to Program FIles(x86), open Qualcomm/QPST/bin/QPSTConfig.exe
8. Now, on the QPST App, select Ports tab --> Add New Ports --> Uncheck Show Serial and USB blablabla. Now, your "modem" will shows there. Make sure that it's the same with COMx in the properties --> Ok
9. Now, press Start Clients --> Restore --> Browse the QCN files on the Downloaded Packages files. And press Start
10. After it "stuck" in 100%, unplug your phone and restart it
11. a) If you have Wifi and Signal, you're done !
b) If you still don't have wifi (Like mine) BUT on About Phone --> Status, the signal shows some number of dBm and ASU ;
To Fix the Signal :
1. Flash the modem that included in the Downloaded Packages
2. Now check
To Fix the Wifi :
Well, this one i found it by myself (i think)
1. Some says that you need to flash ColorOS in order to make it work. But since i don't have ColorOS because of slow download speed, i flash the Hydrogen OS instead
2. I don't know why but the Wifi suddenly work
Now, you should be able to use the Wifi and Mobile Data, and you can flash another ROM
Thanks to @rombdeta for providing the steps and the original thread
Press thanks if it helped you

I was one who messed up with my efs partition and went to no wifi no signal no network
Mine that time i followed almost all procedures from xda but no luck finally i came to rombdeta thread but i actually can't understand his procedure properly tried but no luck
Finally went to service center they flashed oxygen os and everything was came back again they gave me back my phone on the same day but expenses from my home town to service center was 1500 rupees what the f....... K( personally i also tried several times oxygen os but don't know it not worked)
If that time u have posted this thread for how to use @rombdeta procedures properly there will be no head ache.....
Thanx for posting it will be helpful to some one

There is a fix all package on the oneplus forums, that helped me out. I tried everything you stated OP, and my OPO was still not working correctly. After I flashed the OPO windows fix from the forum,my phone is like new. If anyone needs a link, I'll be more then happy to search for it

Thanks for your information

These needs pinning it would help loads of people who done the same thing!
Make an EFS backup!

Thanks this fixed my phone but it has disabled LTE for some reason. I know it flashed the Chinese EFS but I have made the changes to the nvram and it still doesn't connect to the late network.

My guide is already pinned at the top of our section and it contains instructions on backing up EFS.

Well, glad I found this thread. I'm going to try these next. I flashed it back to stock in hopes that would fix my problem. But still got a case of the reboots and a shady IMEI. Man.. Why did I not back up my efs!!! Ugh.. So one a good note, this is fixable, right? Or am I gonna have to go ahead and get the OP2? My OP1 is not even a yr old I should be able to get it repaired, right?

Thanks for the reply. Im busy right now but will try this later. I was worried I had a brick on my hands. So did you lose 4g and if you flash ROMs do you have to apply the fix every time?

I'm trying your method to get back my imei #. I tried every other method in the forum but no gain. Please help me I'm unable to install the drivers. When trying to install driver It says " The specified location does not contain information about your hardware". Please please please help me.
Thanks
Edit:
I managed to install the drivers on windows 10 and restored the imei but now I'm getting only 3g not networks when selecting 2g or 4g. I flashed the XNPH44S-modem from TWRP also. But still no 2g/LTE
Please help.

Worked for me thanks!!!!

It worked me Mate ... Thank You So much ... I recovered my IMEI and Signal is working fine too

fixed mine by just flashing color os on fastboot

Can I fix IMEI on a official rom?? I don't have IMEI on my official rom but my sim slot works and my wi-fi works. should I flash the XNPH44S-modem?
please I really want to get my phone to working again. I am so close!

My problems starts after i flash SlimSaber over the Oxygen OS
Somehow it erase the EFS
Download the package here https://mega.co.nz/#!c0c1lZ7L!ADILW66W-aG0TNcuDzLd13pK6hjcq7omJhPxMiXUjZo
My case : NO WIFI, NO IMEI, AND NO SIGNAL. And on CM11S (install it via fastboot), and rooted + supersu
I did erase the modemst1, modemst2 and the persist. But still it didn't fix it
And i did try to run some command in the TWRP's terminal, but still not fix
What i did :
1. Download the packages
2. Open CMD and type : (Your phone is still on, and on the homescreen)
adb shell
su
setprop sys.usb.config diag,adb
3. Go to Device Manager, and see A0001 on the Other Devices
4. Right click on it and select Update Driver --> Browse blablabla --> Let me pick blablabla --> Show all devices and next --> Have Disk --> Browse --> Now, go to the downloaded Packages, and see Driver --> Select your OS (Win x64 or x86), in my case it's Win x64. Select Select and Install it anyway
5. Now, you'll see it named HTC Modem, now right click on it, but i forgot which tab that i click to see the COMx part..
6. Now, go to QPST folder, and rename QPST 2.7.411.msi to QPST.2.7.411.msi. And now, open Setup.exe
7. Go to Program FIles(x86), open Qualcomm/QPST/bin/QPSTConfig.exe
8. Now, on the QPST App, select Ports tab --> Add New Ports --> Uncheck Show Serial and USB blablabla. Now, your "modem" will shows there. Make sure that it's the same with COMx in the properties --> Ok
9. Now, press Start Clients --> Restore --> Browse the QCN files on the Downloaded Packages files. And press Start
10. After it "stuck" in 100%, unplug your phone and restart it
11. a) If you have Wifi and Signal, you're done !
b) If you still don't have wifi (Like mine) BUT on About Phone --> Status, the signal shows some number of dBm and ASU ;
To Fix the Signal :
1. Flash the modem that included in the Downloaded Packages
2. Now check
To Fix the Wifi :
Well, this one i found it by myself (i think)
1. Some says that you need to flash ColorOS in order to make it work. But since i don't have ColorOS because of slow download speed, i flash the Hydrogen OS instead
2. I don't know why but the Wifi suddenly work
Now, you should be able to use the Wifi and Mobile Data, and you can flash another ROM
Thanks to @rombdeta for providing the steps and the original thread
Press thanks if it helped you
