Hello guys! I have lost my phone recently and I want to try to find it. The small thing is: i'm not sure about the imei number printed on the box, is it really the same with the phone's number.
The thing I have is efs.rfs backup. Should I simply (someone could say, how exactly?) mnount it using gnu/Linux? Is there solutions for windows also. Thank you. Getting gnu/linux now
Added: i've opened it using UltraISO. But is there way to get an imei number out of efs.rfs contents??
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:

Did you first reflash the stock rom? Someone was getting similar error and flashing stock rom fixed it.
Use EFS Professional to write your Original IMEI ....
After flashing some custom rom you may lose IMEI numbers and phone loses its network. How to restore IMEI numbers of MediaTek Chipset phone?

imei reover/repair
Can imei be repaired for sm-g570y ?
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.

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
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.
