"Check your IMEI in settings, about. Mine was wiped. There's a way to write it back.
I'm trying to use this guide:

[Edit]
After flashing my device using LG FlashTool, I used the "LGUP_8974.dll" to resolve "the wrong device model" error printed after a flash. While flashing this, it seemed to display my missing IMEI. Unfortunately when flashing again, it lost the IMEI again. Hm...

EFS. Hope you backed it up... if not, search forums, going to take a lot of manual work in diag mode along with a couple other apps via pc port to rewrite your IMEI.

This happened to me a long time ago on my T-Mobile version and I tried everything I could think of but then I used the tool that you'd use to flash back to stock and flashed it to Android 4.4 and it kinda fixed it so now it doesn't restart much might restart every 20 minutes I never looked at it 4 that long becauseiI bought the international version. So android 4.4 doesn't fix the null imei but now I can use my phone as a media device because it doesn't read Sim cards and at least I can connect to wife so yea

Hi!
I have a D805 and now lost my imei and phone information because i flashed the ROM cloudy G2 3.3 over Cloudy g2 2.2 without back to stock rom.
After that appears the QHSUSB_ BULK error (Multiples partitions), and i fixed with SRK Tools perfectly.
After install the .tot file with LG flash tool, and not appears the imei (says null), and i tried to install original kdz and nothing work.
Today carry my phone to service, and they try to write the imei with octopusbox and not work, throw connection error and in the only moment that conected, says Roaming mask error, betweenk others errors.
Whas can i to do?
Exist any method to write my imei?
Thanks

Messing with the IMEI is illegal in many countries in the world and as such is banned on XDA. You may have to send it in to have the mother board replaced.

Hi all,
I just unbricked my LG G2 from QHSUSB_BULK state and flashed latest official Lollipop from LGE. Then I fiddled with some bands in QPST (as per this tutorial) and when I tried to write them to phone, I got a message box saying "ban" and after that, that "IMEI" failed to write.
After this every time I boot up the phone with SIM inserted, Phone and Messaging processes crash and there is no IMEI displayed (null).
If I take out the SIM card, I can read the IMEI of the phone OK. The SIM is also OK, because I'm currently using it in an SGS and used it before this in the same G2 and it worked.
Another thing I noticed that might help, when the SIM is inserted, the modem seems to be restarting continuously:
- Phone/Messaging crashes
- In QPST, where the modem build is displayed, it appears and dissappears
Any ideas on how to fix this?
Does it sound like a misconfiguration in QPST or a modem problem?

hi kalpesh! why don't you reply here instead of teamviewer?
Ok, I tried to rewrite the backup qcn file but I receive "Phone sent an invalid command" message in QPST. Do you know what the problem could be?
OK, finally solved it! So happy
In order to restore the qcn file, you must first zero out the modemst1, modemst2 and fcg (NV data) partitions with dd, or else QPST won't let you restore them.
ALWAYS backup your modemst partitions before trying anything funny, kids!
I am having hell of problem with my At&t G2 D800. For last 2 months I had issues like INVALID CARD every time I restart/Power off my device.
From last week it got permanent and now I have IMEI=0 , Unknown baseband and Service disabled.
Don't have backup of EFS
Tried Flashing Stock KK Firmware but no way.
Tried to fix IMEI with EFS Professional and it says succeed but after restart its still same.
Can any expert help me or anyone can say is it possible to get my phone fixed? Or should buy a new one

Hey, I have the same problem, I guess that there's not solution yet.

Do you a have a efs.img backup ? Or any kind of IMEI/EFS/RADIO backup ?
I had the same problem I flashed the stock ROM and somehow I lost my IMEI info, I tried everything and I was even thinking about buying a z3x box but then I decided to do a very risky move , I completely deleted all the EFS related files/info and reflashed again but now I was not able to boot because I always sent me to recovery mode saying that :
"E:Failed To Mount /EFS (invalid argument )"
Then all I did was installing TWRP and rooted my SM-G935F and then I placed my efs.img backup on my internal SD CARD and went on recovery launched the terminal and wrote this :
dd if=/sdcard/efs.img of=/dev/block/platform/155a0000.ufs/by-name/EFS
Then I wrote reboot and it finally my phone was booting and I recovered my IMEI and was able to use my phone normally.
This only works if you have a backup of your EFS, and even if you do is risky , but I did it because I lost all hope and was accepting the fact that my phone would just become a useless wifi only device .
So there is not a fix yet for this problem ?
I have a problem on my s7edge instead. If i have valid imei i'am almost always in emergency calls, and when the signal comes back does not go into mobile data connection. With the wi fi no problem.Can someone help me i'am going crazy.!

IMEI, Network Signal and Baseband is misssing
Hi
I am ready to donate if any expert can help me to restore IMEI.
I am using SM-N9500 samsung note 8 model - hongkong version, i frequently change the roms.. when last time i tried to install a custom rom i lost IMEI. i am getting error like IMEI-unknown, baseband- unknown, no network and sim cards not working..
i tried installing stock rom, custom roms, it was installing successfully but only baseband, signal and IMEI are not working. i didnt even back up my EFS folder. So, kindly help me to get back my IMEI.
I have installed stock rom, still no IMEI. now i rooted my mobile and taken EFS backup. is it enough? if yes, pls suggest me the next steps. I also tried installing combination firmware, though is not working, installation was successful and also i am able to see the factory binary logo, after which it will switch off automatically and boot loops. everytime it will open factory binary and immediately it will switch off automatically..
