Dear All Hi,
I have 2 china phones with Android 2.2
which are exactly the same.
After flashing one of them
I get the message:
Invalid IMEI
and the phone cannot connect to
mobile networks and make calls anymore.
Is there a way to copy the good IMEI
of the phone that can make calls
to the invalid IMEI
of the phone that cannot make calls?
Thanks in advance for any info,
ff
can you revert back to the factory or stock ROM, hard reset or something?
Thanks for the reply.
I did the factory data reset
(Settings > Privacy)
but again the same:
Invalid IMEI in the status bar
no mobile networks can be connected
cannot make/receive calls

Please help,

Its probaly because there made in China, and they don't have original Android License.
Did you install a rom that was made for your phone, because it is chinese you know. And you should indeed go back to stock rom
I have installed the rom that was made for my specific phone
and the specific model that i have. (2 of them)
I flashed the phone to get the latest firmware that the phone maker
said was released to fix a lot of bugs.
The phone maker also said they had tested the flash tool
with the latest firmware and the phones were working OK at their end.
But in my case the phone although it was working fine before the upgrade
after the upgrade it shows in the status bar "Invalid IMEI"
and cannot connect to networks and make calls.
Any ideas anyone?

Be sure you installed it right. Do factory reset, or search if patch is avaidable

Fixed it!
Invalid IMEI
Had to:
1-root it with "SuperOneClick"
2-install "root explorer"
3-copy the file "MP0B_001"
from the good phone to the bad phone.
(Location: /data/nvram/md/NVRAM/NVD_IMEI/.. )
Before rooting, the above file should have been backed up,
but i had the same phone working so a copy did the trick!

great information, bookmarked for future reference if needed, thanks!
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:

Go to
Settings/Mobile networks/Network operators/Search networks
And choose your network
If didnt work try to flash your mobile with latest Rom using (smart switch) keep in mind you will lose all data on your phone if didnt work try Marshmalow beta....any way try roms and do same steps...

i can change imei easily with your instructions provided,but serial number? ( it works for me i can change my imei to whatever i want to....S/N is easy only modify serial_no file inside \efs\FactoryApp ) <<<<could you explain this? my emei seems to be finally corrupted so only way to get it back is write in id changer manually,so do i need to backup and restore it anyway?
Dude just restore this efs backup with twrp recovery https://www.mediafire.com/?loh80547x1k5cg8
It will say null or something then try to fix imei with apps inside folder...if this didnt work visit repair place...
Sincerely hope you're not in the UK as it's very illegal here to change IMEI and advertising the fact isn't a smart move.
Greetings,
Changing IMEI is illegal in many countries and the discussion thereof is prohibited on XDA.

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.

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.
