[Q] Invalid IMEI

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

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

Dont say 'thanks', just press the button

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!

How to fix LG G2 with IMEI issue

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:

I keep getting
Exception Thrown!!
NvManager::getNvItemsFromPhone( const string comport )-
QpstServer::sendSyncImpl - Bad response from phone (DM packet

Any ideas? Please tag me in this.

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 ....

[Q] I need to access data from deleted text messages right before a back up was done.

I don't care to reinstall it back to the phone, I just need to get all of my model and serial numbers from the equipment I was working on in some kind of format that i can email my boss.
Can I just get some program that will change it to word or notepad?

Goto you settings and check your imei number and check it against the tag on the case under the battery if its what I think it is I had the same when I had a i9100 basicly your efs folder has courpted some how by rights you should of done a back up do a bit of googling its very common and could be easy to restore if I'm correct your device will show a generic imei like this 004999010640000
If yes there are apps on play store that could help restore your efs folder
DO NOT POST YOUR ORIGNAL IMEI ON HERE
if you get stuck pm me and I'll help best I can

There is an amazing guide on here somewhere do a search for it but it shows the steps to take to restore your data settings. u need your msl number there is an app on the market just type msl (must be rooted) and the dial code is ##3282# it will ask for view or edit mode and then the msl code there u can restore your data settings

after i reflashed the stock rom again, it showed that it's /01 = (nothing)/01
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.
And i don't have a backup.
