Long story short, I bricked my lg g2 d801 after flashing twrp recovery and trying to flash custom rom. The phone would restart randomly. I had no connection and the signal bars crosses out in red. In settings most of my info like baseband, imei etc were missing. I was looking up and many people bricked their phones with no EFS backup to restore the IMEI. This is how I fixed my phone. This should also help people who have zeroed out IMEI after bad flash or whatever reason. But you should at least have IMEI number ready (from your box/ receipt or call t-mobile)
1. Flashed the phone to factory firmware using LG support tool. I used the following guide:
http://androidcure.com/unbrick-lg-g2-stock-firmware/
used the firmware: T-Mobile KitKat D80120A_00.kdz
there's also similar guides in xda, follow whichever you prefer. Goal is to revert the phone back to stock.
After flashing the phone, the phone was woking; however imei was null. In phone settings my IMEI was 0. To fix the null/bad imei follow this guide (Not all the steps are my work; this guide helped me http://forum.xda-developers.com/showthread.php?t=1942417 , also watched some you tube videos):
2. You need the following drivers and software:
LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.10.1
QPST_2.7_378
imei converter: http://www.sendspace.com/file/a3spfh
3. After installing the driver; turn on USB debugging and connect the phone to computer
4. Install QPST, run QPST configuration from from start menu
5. Click on Ports tab. Click Add new port. Your phone should be COM4/5. It will say USB after the port. Select the port and click OK.
6. The port should come up on active phones. Select the phone and and click on "Software Download" from start clients menu
7. Click on Backup tab. Your port should appear. Backup by clicking on start
8. Now go to Program Files/qualcomm/qpst/bin folder
9. Run RF_NV_Manager program
10. Click File read from phone. Your IMEI should appear on number 550; NV_UE_IMEI_I
11. In my case; there was no item 550 as my IMEI was missing. Don't worry.
12. Click on file> Read supported RF NV items
13. Now click on item 550. It should show 9 blank fields.
14. Start IMEI converter. Type in your IMEI in enter IMEI click on convert IMEI
15. There will be 18 digits in groups of 9
18. In RF_NV_Manager program; click on Hex by Write NV button
19. IN the 9 boxes; type in the numbers from IMEI converter starting from left. Type in first group of two numbers in the first field, then go to the next field and type in second 2 digits
20. After you fill in; click on write NV
21. Now click on File> Read from phone. NV item number 550 should appear now.
22. Unplug, Restart your phone and your IMEI number should be there and phone should connect to network.
Above process fixed my phone with full 4G LTE data. Now depending on the how bad your EFS was damaged; you might not get 4G lte data. But at least now; you will be able to send the phone back to LG for repair or return to t-mobile as IMEI number will be in your phone.
You can do this with EFS Professional. It does all the conversion for you and you dont need QPST. Just simply type in IMEI and write to device.

I've tried the this guide and it didn't work for me. I get an error when I try to write NV. The good news is that I don't have an immediate need to change/fix IMEI but I was wondering if it ever gets zeroed out I have a way to restore it. I will give your tool a try.

So the EFS Professional is compatible with phones other than Samsung? Once I've unzipped the file I see a bunch of binaries for Samsung phones, but nothing for LG G2. When I try to run it generates an error the app is for Samsung devices only... Where can I get a compatible binary for LG G2 or EFS professional that works with LG G2?
I've tried Qualcomm NV Tools instead of EFS Professional and I cannot create a backup. When backup is being created it errors out saying the device has been disconnected... Also if I write the IMEI it says it was accepted but it doesn't change.
PS: I should probably start screweing around with these apps since I may introduce the problem. My IMEI is fine.

Imei will only write if zeroed out. You are correct, EFS Professional is for samsung devices but the Qualcomm NV Tools is universal. I am currently in the middle of updating it so more features can be used on other devices.

Hey kingroach, amazing guide, wonderful!
I followed everything step by step. Right now I have some generic IMEI which does not work, I'm trying to write my original one back, but at step 20, when I click "Write NV", the numbers change, the Hex unchecks and the popup comes out. When I close it, Hex goes back to being checked and numbers return to what I made them. and I get this popup:
Here's a video.

Hi, thank you for your help too in these threads. I tried EFS Pro, everything checks out, it says IMEI written, but when phone is restarted, nothing has changed. Do you know if EFS Pro need some other setting enabled to actually change the IMEI?
Try deleting 550 nv item which contains the imei and save. Restart the phone and add it.

I couldn't - you try with the custom list, under tools I think. You move item 550 from the right column, and it dissappears, but when I read NV phone items, its there. It's untouchable I tell you!:silly:

How To Upload ERI using Revskills
Manual Method / How This Works
The IMEI part is complex and I wont go into detail on that at all. If you dont have access to a windows machine, then I'm sorry but most of the avail tools that will allow you to repair IMEI is going to be Windows based and you can use a virtual machine. Not with my tool but others. This is mostly going to be focused on the ERI it self.
The ERI is binary file that is stored on the QCOM chipset, this is the primary file the "Radio" and the device use in order to determine certain functionality of the device.
This is stored as /nvm/eri_0 on the QCOM's EFS. You can use QPST EFS Explorer all though it will probably crash, or some other EFS explorer for Qualcomm chipset's.
I have uploaded the original eri_0 file to this forum. All you have to do is download it. User QPST or Bitpim, Revskills, and upload the file to /nvm/eri_0 you can leave it's permissions as 666 or chmod the permissions to 777 your choice the phone will read it either way.
The /nvm/eri_0 that is uploaded to this forum comes from a stock s3, although its the same ERI file Verizon has been using forever. Thats all this tool does. Simply fix's the IMEI and uploads a good eri file to the correct directory.
Questions and Answers
Q) Do I need to do anything special first like back up any part of my phone or anything ?
A) No, as long as you can enable diag port you can restore your IMEI, just look on the back of your device under the battery for your original IMEI. I STILL ADVISE YOU TO BACK UP using this method here http://forum.xda-developers.com/showthread.php?t=1852255
Q) Can this change IMEI?
A) Its purpose is not to change IMEI doing so is illegal and any talk about changing the IMEI will be reported and you may be banned. I advise against it as it could cause unknown issues.
Q) Can you share how this works.
A) No, sorry my position, my family and my job comes first and this would put me in a bad position.
Q) Can you just tell me in pm.
A) No so dont bother asking.
Q) My phones says Roaming and show roaming icon will this fix it ?
A) Yes this should be able to fix that issue, it does that by uploading the ERI back to the QCOM chipset.
Q) Should I / Do I have to donate ?
A) No, you don't need to donate, and I don't want you to fell you need to. Your donation could go to something else EFF, Adam Outler, XDA, Poor kids in any country, some other foundation. If you feel you would like to donate to me you can, I wont stop you and I wont ask you to.
Credits
Not sure who all to credit if you feel your name should be here Just tell me and why and Ill post it here. I did not read any of the other forum really, but ill list who i have seen and who as helped me identify it was the ERI
Also no particular order
Adam Outler - For everything he does, I watch a lot of his videos.
WildZontar - For his thread, not sure if its his info or just info collected. - http://forum.xda-developers.com/showthread.php?t=1852255
TrevE - For what he has contributed, looks like a lot very knowledgeable person
Jay Evans - For doing the initial tests
BillBauman - Discovered the missing ERI
GerardAnthony - For the AOSP mode scripts
Again, for these people as well, I didn't read the whole thread etc to see everything they contributed. If someone would or if they would / want me to update it please ask to me to update so I can give credit where its do.

It's possible but it would have to be written for that device, meaning I would have to have test device or some way to check stuff.

if it works fine if i take it to some guy who has a box i will.
if it doesn't tell me what to do please

It happened after a failure attempt of changing the imei because in turkey if the phone is not from turkey region you need to change the imei to a turkish one.
And i didn't flash a custom rom only stocks one.

K thanks for helping.
I got this phone (Lenovo A606) about a month ago with the following problems:
1) Modem (the one with the SIM card) doesn't work, status in the about section shows "invalid IMEI" and "unknown baseband". SIM card settings are greyed out in the settings.
2) Wi-fi works fine, but i always have an additional SSID in wifi menu that says 0x010 something error
According to previous owner, it went bad after bad flash or update, but he might have been lying and modem is physically dead due to some reason.
3) Serial number is also a blank
So far i've tried:
1) Flashing different stock firmwares with full flash format and DA DL flags checked/unchecked in SP Flash tool
2) Fixing nvram/trying to restore IMEI and SN through numerous tools of different versions: Maui Meta 3g, SN Writer tool, SN Station Writer tool, infinity box CM2MTK, etc - every one of tools that i've tried (i've also tried different versions of the same tools) show me different errors, best solutions online for which are "check your drivers, change usb cable or change computer" all of which i've obviously tried with the exact same result
3) Fixing nvram by deleting nvram folder in /dev/nvram
4) Replacing MP0B_001 in the nvram folder (rather putting it in, the target folder is empty after stock flashing)
5) Using nvram fixes through both custom and stock recovery menus prepared by the poor bastards like me, but with more knowledge about this stuff
6) Flashing nvram from a donor working phone through SP Flash tool
And since i'm making this post nothing of the above has worked.
So far i've came up with two possibilities:
1) The modem is physically dead and i lost in total 72 hours of my life on a goose chase. If this case is true, how can I make sure of it? Is there a low-level recovery menu or a factory mode that can confirm/deny it?
2) I'm doing something wrong and there is a simple fix for it. In this case, I ask for help guide me in the right direction, if possible with exact instructions.

I got this phone (Lenovo A606) about a month ago with the following problems:
1) Modem (the one with the SIM card) doesn't work, status in the about section shows "invalid IMEI" and "unknown baseband". SIM card settings are greyed out in the settings.
2) Wi-fi works fine, but i always have an additional SSID in wifi menu that says 0x010 something error
According to previous owner, it went bad after bad flash or update, but he might have been lying and modem is physically dead due to some reason.
3) Serial number is also a blank

Greetings and welcome to assist. Changing IMEI numbers is illegal and can not be discussed on xda so we have to be careful. If you have the original IMEI number it may be possible to restore it with an octoplus box or something similar but we are limited to what can be discussed on xda

Never tried to change it, since there wasn't any imei in the firmware to begin with. I only fruitlessly trying to return sim functionality
Lost IMEI and Baseband on your U Pro.
lets search for a solution.
forword:
if we flash the 2080227 stock rom we will lose the IMEI and Baseband information in Settings.
the IMEI and Baseband is still there its just that it dont show in settings anymore.
Why:
stock rom 20180227 contains all images of the official Stock Rom as dump.
also modemst1.img and modemst2.img. in that images are the imei information stored.
baseband information is stored in fsg.img
but why it dont restore also the imei info in settings ? maybe its region related. we dont know that yet.
lets Discuss and find a Solution/fix for that
reserved
here i will post the possible solution ..............
1.
This will restore the IMEI numbers into settings for slot 1.
Slot1 and slot2 will be similar then.
1. Install xposed manager APK. You have to have root for that.
https://xposed-installer.de.uptodown.com/android
2. Download in the app framework v90.beta3 and install it ( all in the app)
3. Download this app from playstore (IMEI changer)
https://play.google.com/store/apps/details?id=com.vivek.imeichanger
4. Your imei is written on your u pro box back cover.
Enter the IMEI in the app. Save it and reboot.
Done!
can you maybe transfer from eragon rom thread to here the posts concerning imei?
thank you

LOL . I did not tested that.just uninstalled framework and xposed app and the IMEI is gone. You are right. WTF
In ~2hours I will know if the other fix I found will work
Maybe helpful information:
For me without any changings the IMEI isn't gone. With *#06# I see two IMEI
I'm on eragon 4 but I've had to make a factory reset after update from 3 to 4 (there were some problems like system settings not working)

I guess the problem of losing the IMEI was caused if someone flashed the stock rom 0227. It was overwriting modemst 1 and 2 where the IMEIs are stored. Eragon doesn't do that.
I have found appropriate tools (also via xda), which perfectly fulfill the task...
QUALCOMM smartphone write IMEI tool 1.01
QMSL IMEI and SN writer 1.4
But apparently the tools do not support the chipset, or I have not yet found a way to use the tools accordingly.
If someone has experience with these tools…
Thanks in Advance

Already tested them a few days ago. They don't work.
Feedback of my progress so far:
I use NV ram tool to try to restore IMEI.
I was able to build IMEI but it did not flashed it because of a driver (diagnostic mode) problem.
I just have to find the right driver. Lol.
Sound funny , but I have around 100 different diagnostic drivers for Qualcomm devices.. one is the right one I hope ....

all the best man to succeed, we are with you
Been looking through XDA threads hoping to get some ideas on missing IMEI thing. I'm also trying to run a NV Backup using the QFIL program and up to now I wasn't able to do that, the blue 'start' button was always disabled(diagonal gray stripes) with the COM port and diag driver ON. I think, the problem is related to the lack of IMEI/ESN etc.., because today I hooked up my spare Moto G4 Play and got the NV bckp from it. Then, after that, I actually had a little success with Upro, I used the same diag driver which poped-up with Moto, HS-USB 9091 (instead of 900D), it's also a Qualcomm driver, found it on my desktop(uncheck: show compatible drivers to see it) Not a total success but, at least I could start the bckp. It failed, still, I've never gotten this far. Can you try and see if you're able to get the NV backup w/o IMEI#?
Is there a way to somehow convert to text the .qcn files? How about editing it, if that's possible then the imei could be written into saved files and fed back into the phone using 'restore'. Just saying, am clueless on that.
Ok, here is that link from another XDA thread and you'll find two screenshots below:
https://forum.xda-developers.com/moto-g4-plus/help/diag-mode-g4-qpsd-t3591683/page2

https://drive.google.com/file/d/1xawPNNMCD39nzQJaoBfwwnf0zVFCwQTA/view?usp=sharing
I am ready to try the IMEI edit on my Upro. I was dry practicing today on .qcn files extracted from Moto 4g Play, navigating the .qcn with this editor http://mh-nexus.de/en/hxd/ , finding the proper columns and rows, playing with hex./dec. conversions guided by this: (watch?v=zn_D6TEFABQ)
But I'm still missing the most important element: the actual Qfil generated .qcn backup files from my Upro, can't get it. You guys have any suggestions?

Its a placebo fix or better only a solution for fake/anonymize the IMEI for apps only!
If the provider needs the IMEI to connect to his network it is not working!
With a app on phone you can not bring back the IMEI, its stored in the NVRAM.
You have absolut no write access to this "partiton" on a running system.
for real restoring you must flash it!
Anyone left with some humanity is requested to PLEASE HELP ME if you have a Redmi 6a device or know a guy with redmi 6a device.
I actually bricked my device unintentionally and did found a way to get out using SP Flash Tool, However the thing I am stuck in right now is worse than bricking a phone.
Both SIM Cards are not working. I did a lot of research and found that I need two files:
[nvdata.img] [nvram.bin]
Unfortunately I don't have any backup for this. Now what I am looking for is some kind hearted person who can take a backup of their [nvdata] [nvram] partition and give it to me and I'll replace all their data like IMEI numbers etc with my own. I have my IMEI numbers ready to be feeded. I did a lot of try using those engineering ROMS and Tools. NOTHING WORKS!
I regret my decision of jumping in something I don't know about. I want you to please have pity on me so that I don't have to live without my phone.
==============CURRENTLY ON NEGHBOURS WIFI WHO CAN CHANGE PASSWORD ANYTHIME IF HE GETS TO KNOW THAT I HAVE HIS PASSWORD BEFORE HE DOES THIS PLEASE GET ME OUT OF THIS SO THAT I CAN USE MY OWN PHONE FOR INTERNET. I AM COMPLETELY DEPENDENT ON CELLULAR DATA!===============
====YA I AM THIS MUCH POOR!!!==== NO MONEY FOR A NEW PHONE====I AM NOT STEALING ANYONE'S IMEI====PLEASE HELP!=====PLEASE HELP FOR HUMANITY

I tried it but it still shows imei unknown. What device is your fixed mobile phone? xiaomi or some other?
IMEI gets added to mobile device when it's built. It's stored in device's /EFS and/or /NVRAM partition. If you haven't backed up this partition before you flashed a new ROM then you have lost unless the IMEI is printed on the box in which device has been delivered.
