Thanks for your reply.
also tried to flash through fastboot rom but no luck, issue still exist.
I didn't backup efs so I don't have it.

Try unofficial unlock bootloader bro vl work..u could request note 3 qcn file of note 3 users..I'm currently using z2 plus

Flash the right firmware for the device (if you don't know which one is the right, just keep trying until you find one that is working) and it will solve the problem (it solved mine without reinstalling ROM or anything just flash firmware, reboot and enjoy). If you flash any miui based ROM, you always have to flash the firmware otherwise this will happen again.

I have problems with IMEI and Mac (wifi). I fix this with QPST and clean flash.

1. you must see IMEI code itself is usually present in your device box or you could find it from the back of your device just right behind the batterai. example: IMEI: 3567XXXXXXXXX
2. after finding the code install Android Emulator and after installing just type the command "SU" without the quotes
NB: The Android Emulator with linux commands
3. then go to the root by type SU, and type this
echo ‘AT+EGMR=1,7,”YOUR IMEI“‘ >/dev/pttycmd1
4. finish
hopefully this help :highfive:

I lost my IMEI on my Sony Xperia Z tonight, I do not know why or how.
I used the command you give above. Exactly as you describe, in a terminal with root. I rebooted, but still no new IMEI. Why did the command not work on my Xperia Z?
I just see, I do not have an /efs folder any longer. Does CM store a backup of working IMEI somewhere?
I do not have an EFS backup, what else could I do?
EFS i think work only on Samsung Exynos devices

I was able to fix it by formatting all partitions, including /data and /system and installing CM again. Then the IMEI was back. I did a re-format, not just a wipe in Clockworkmod recovery. You may try the same. Format *everything* and install CM 10.2.0. Maybe this will restore your IMEI.

My phone also encounted the same problem after flashing Custom ROM from needrom.com. Did you make a full backup of your phone? If not then it's too bad and you might need to sent your phone back to service center.
You can try this link for tutorial and see if it works to recover your IMEI and baseband, if not your last resolution is send back to service center.
http://lenovop780en.blogspot.ro/2014/01/faq.html
And after your phone back from servicing, next time remember make a full backup incase anything goes wrong. Post #3

Hi,
I think u need to flash your rom once again.
Use flash tool to install the same.
But before that connect your phone
and go to format- format whole flash-ok.
For this u need to select the scatter file from your firmware.
After this download your firmware( not firmware upgrade)
also click on check box for D/L.
After flashing new firmware you need to use above steps which I described earlier.
Good help you.

Hi I wonder have you resolved your issue or not? Actually I found a consider temporary solution.
With your phone rooted, using any root explorer, navigate to /data and copy the nvram folder to your memory card (as a backup). Then delete the whole nvram folder in /data. Wait a while, your phone should have signal and baseband already. If works let me know, I will tell you what to do next step.
Hi, I repass two phones in one, can not find a signal. I do not know what is meant by this icon:
Please, do not know where is the mistake? thank you

IMEI Unknown/Sim card not detected after OTA

Ok i need help with my device.
I got a s6 edge SMG925I a while ago, yesterday an update (i guess its called OTA) popped up and i installed it. after the installation was completed but now i'm not registered on network, and i can't detect my SIM card.
Note: my IMEI is NOT blocked.
So far all my efforts were for nothing.
All the info i got so far by searching
Problems:
Not registered on network
when typing *#06# it only show S/N
About device it shows IMEI: Unknown
did not back up the efs folder (but i GUESS the folder is still there and somehow the new stock can't access it)
Android ver. 6.0.1(marshmallow)
Possible cause:
EFS Folder corrupted
Bad Stock installation
Already tried:
Rooting (i wasnt able to root)
Installing latest stock rom
installing the old rom
QPST to change IMEI
Please help me guys
EDIT:
I figured out what happened, my efs got deleted somehow, i got no backup, is there a way around this? help me please

How about a simple reset from the settings menu? But I am pretty sure, if you somehow deleted the IMEI imformation, your chances are not the best. You'd have to find a way, to get write thatbinfo back. What you could do is ask someone else to backup that partition for you and change the values according to your phone ( IMEI, serial number,...) Then flash this partition info back. Good luck!

i think you can install CM recovery (TWRP) then you can process the backup of your old rom from the recovery.
just enter in recovery mode then you'll find "restore" choose all the files ( i think there will be like this: System, Cashe, Efs, Boot...) then hit Restore botton, and wait for it to boot up hope this helps you bro

Try to get the efs partition holding the information from someone else, change it to your IMEI, serial,... And flash that partition to your phone and you should be good. I guess you'd have to use a hex editor to get that done. I am not rooted, so I can't back it up for you.

Redmi 5 plus MEG7 need modem files

I need these files please if somebody can share:
- modemst1 - modemst2 - fsg
Due to a kake ROM now I have corrupted my EFS partition and need those files to bring alive my device. Please help.
I have found MEE7 files in the web but I guess don't have to use on my phone.
Please, somebody with MEG7 can help me? I will be very glad to buy him a beer.
Hey there! I'm not currently at home now, but I can give you a direct link to NEGMIFA Rom(for Global Version phones), you can extract files you need by yourself.
Download_V9.5.11.0.NEGMIFA (as you can see, its an old version)
OR you can download_fastboot_ROM, and flash it with MiFlashTool, it should solve your problems.
Have a nice day.
P.S. If you cant download something by any reason, I'll make a mirror on googledrive or other filehost in an hour or two when I get at home.
I read somewhere that modemst1 and modemst2 contain IMEI so the rom doesn't have those files.
Fsg is also related to IMEI
Well, as far as I understand your phone not working at all, correct me if I wrong. So my algorithm to make it work is to flash it first(fastboot), doesnt matter with or without your IMEI(I think it'll be 0000), then you can search on xda or whatever, there was a bunch of threads with IMEI "problems", I'm sure you can find the right one.
Have a nice day.

Hi Dunaldo, thanks for your time.
Currently my phone is working on official miui 10 developer rom, it was bricked until I could open the bootloader and install twrp.
Now, the problems I have are:
1.- Baseband "UNKNOW"
2.- When I digit *#06# on the dialer: "UNABLE TO GET IMEI"
So I was reading a lot in the forums, and ,my conclusion is: I have corrupted the EFS partition or probably I lost it, then I need first to solve the "baseband" problem, for that I need the modemst1 - modemst2 - fsg files of my exactly device model and then I can get back mi unique IMEI.
By the way do you have the MEG7 model?
And thanks for your suggestion about flashing fastboot rom, I will try once more, don't think will resolve the efs problem but I'll try anyway.
I have the same problem & i have used the files ur looking for but everytime i restart the phone my baseband again becomes unknown ?? if u want i can give u the file link tomorrow but its no use
Search Qcn file in google for your model . restore it using QPST and write your imei thats all tested MEI7 works perfectly
Any solution?

Hey there! I hope you are doing well. Could you please tell me the process? I am be so glad if I can recover this phone. I have similar issues like you.
After unlock, i always do a full backup of all block partitions. It saves many issues

IMEI null ,baseband unknown how to solve?

After unlocking the bootloader flashed magisk and data decrypt imei and baseband are lost can I restore it?before going to service center:crying:?
Download a global Stock ROM for your device and just run the flash all.bat file and let it run may take awhile and phone will be fresh again
HELP !!! I'm getting the same issue but don't care if i brick the phone.
No matter how many times i flash use different roms i still lose my IMEI/Baseband
I have an external SD card but it looks complicated to backup the EFS file to the SD card and then restore it to the phone but is that my only option ?

Download a global Stock ROM for your device and just run the flash all.bat file and let it run may take awhile and phone will be fresh again

Don't disable forceencrypt, that's your problem.

Did you flash a recovery rom or a fastboot rom? You should find flashing the fastboot rom restores everything correctly.

I tried restoring the phone using a fastboot rom, but the baseband and IMEI errors still appear. Does anyone know about another solution or tool for this? I know both of my IMEI numbers, by the way.

Every time I got this problem I found that flashing a fastboot ROM fixed it. I never managed to find any other solution that actually worked. Googling the problem I did find some solutions, but I didn't try them all. I just gave up and kept stock ROM with Magisk, then debloated it as much as I could. All I can suggest is seeing what Google throws up and seeing if any solution works for you.
anyone found a fix yet?
I have the mistake of rooting my device and disabling the encrypt, Now I have unknown baseband and my imei is blank. What do i do now?
