Hello,
I have a Lenovo K3 Note (k50t5) that I bought from China.
Since it came preloaded with a lot of bloatware and without an option to update to newer builds from Lenovo, I flashed the Indian ROW (rest of the world) k50a40 version and updated to the latest S121 version.
The problem is that the IMEI got deleted and I couldn't fix it with numerous methods I found in various forums.
I rooted the phone using the CWM method.
I tried using Mobile uncle app, but it doesn't have the engineer MTK option for some reason, only Android.
I accessed engineering mode through the dialer (*#*#3646633#*#*), and tried using AT command but it gave me the common error that it cannot send the command in user mode. Making a space before the + sign just gave me an ERROR, without specifics. I modified the build file from user to userdebug, and now I always get ERROR.
The weird thing is that I get a data connection from time to time, but I can't make phone calls or send SMS. Any help will be greatly appreciated.
I managed to fix the problem! I'm posting this as it might help other people with this problem (invalid IMEI).
Just download an app called "chamelephon" from google play. it allows you to type in your IMEI.
It fixed the problem in 1 minute. Now I can call and send/receive SMS as normal.

Hello everybody,
I bought recently my thl W8S, and I was experiencing some troubles with the battery charging (taking 10 hours) and my GPS connection.
So I decided to flash it via CWM. But I'm very new in the flashing and all this stuff. I tried a lot of things to get CWM , even thing I didn't know.
The problem of my IMEI came out atfer I installed this :
http://forum.xda-developers.com/showpost.php?p=19319421&postcount=23
The recovery installer apk, I just click on it and when my phone rebooted, I didn't have any access to my SIM management, no more coverage of course.
I tried the *#06# and my 2 IMEI are just marked as "INVALID".
Since yesterday I tried few different operations to get if fixed but nothing is working.
I tried to use the engenering mode (menu CDS, Network information) and send the AT command with the IMEI but I got an error message : AT command is failed to send.
Then I tried to recreate the MP0B_001 file with some tools I downloaded. And I put it in the right folder (/data/nvram/md/NVRAM/NVD_IMEI/MP0B_001) instead of the old file. I reboot my phone, still the same trouble.
I'm kind of desesperate right now.
Any thoughts / ideas?
I can't find the stock rom to try to flash it with Odin ..
Thank you

Hi, Did you finally managed to fix the imei issue? I have the exact same problem.
I have the exact same problem. Who successfully solve this problem?
If you didn't back up your efs partition then the only other allowed way is to send it back to the oem.
Thread closed.
Before I start with the issue, let me begin with some basic information: This is in regards to my Samsung Galaxy S5 SM-G900T (T-mobile), running Lollipop 5.1.1, FOG6 build, DOB1 baseband, rooted, deodexed, but otherwise stock.
My problem: Today I flashed a rom via Mobile Odin Pro and soft-bricked my device. After a lot of hair pulling and screaming at my phone and computer, I finally got my phone up and running again. After trying many different solutions, I eventually tried re-flashing TWRP through Odin (recovery initially would not boot, hence the soft-brick), which succeeded, and then recovered my phone by restoring from a previous backup.
This got my phone up and running again, but once it boot, I had no service. I first checked my APN settings, but was presented with a message stating, "Unable to view the access point name settings. Access is restricted for the current user profile." I tried adding a new APN, but once I added it, it did not appear in the APN list, which continued to only display the above message. I then tried to "Search now" for Network Operators, but nothing was found. So next I checked my IMEI through "About Device", and discovered it was set to "Unknown". Checking the IMEI through the dialer (*#06#) lists the IMEI as "null / null".
I have searched high and low and tried everything I could find to fix this. I tried restoring my TWRP EFS backup to no effect. I also tried flashing the modem through Odin, as well as restoring my TWRP modem backup. I tried using an Xposed app to manually set the IMEI back to its original value (I happen to have my phone's original IMEI number written down from when I SIM unlocked my device), but while this updated the IMEI displayed in the dialer (through *#06#), it did not change the value in "About Device" and did not restore my service.
The last solution I tried (found here: http://www.technobezz.com/restore-galaxy-null-imei-and-fix-not-registered-on-network/) involves me using the dialer to enter Service Mode to make some changes; however, while dialing *#197328640# did open the Service Mode menu, the menu was totally blank.
Please help! Given the current state of my phone, I cannot make or receive calls or texts or do anything else requiring a mobile connection. I have looked everywhere and I don't know what else to try :crying: :crying:
Assistance in this matter would be greatly appreciated, as until I am able to fix this, I don't have a functional phone
Any suggestions?
Hello XDA, I have been a user/fan of xda for about 5 yrs now. But I havent found a single problem that I didnt find the
answer for here on xda, or somewhere else (Google). I have a Computer and Phone repair shop in Ethiopia and I used the
internet and mostly XDA to Unlock Sprint HTCs, Unbrick Galaxy S/ SII/ SIIIs, repair corrupted efs partitions, install
custom roms like CM (on almost every smartphone I come around), fix bootloops of Best devices like Xperia Z, Galaxy SIII,
Sim unlock Moto Droid ...
But I have faced a serious problem and have been trying to solve it for about three months now.
To the real problem
There Are these MTK MT6582 Devices, Mostly Huawei devices (G730, G610, G630) and they are recently getting a major IMEI
failure (IMEI : null). I have tried through the ff methods (that I use for other MTK devices like MT6572, MT6575) With no
luck
1. Maui Meta 3G - It reads the devices in meta mode
- It can read the version (in "Get Version" window)
- I have selected the Nvram database of same baseband
- It fails to write the imei when I click "download to flash" It either replays "Check the load and device versions are the same (ish)" or "Download to flash time out"
2. IMEI & SN Write tool - Doesn't seem to read the device in meta mode.
3. MTK Droid - Rooted the device
- Restored "nvram" from another working phone
- Rewritten the IMEI
- Still the same (IMEI: Null)
4. Reformatted the whole device and installed firmware with "secro" file - Still the same - tried the above methods again, still the same.
Dear XDA Fellows, I am exhausted with these devices and they are keeping coming. So, Please help me solve these problem. Thank You.
P.S - I dont know where to post this, if there is another appropriate thread, lead me.
I bought a new Lenovo A806 (original version android 4.4.2 - build VIBEUI_1432_ST_A806).
There were lots of Chinese writings imbedded in the rom and apps so I rooted the phone and tried to disable some apps and stupidly removed the stock phone dialer and contacts. Then whatever replacement app I tried from the Google play store did not work.
The replacement dialer gives me the message:- “You have removed/disabled Stock phone application, its required to properly functionality.” (pardon the Chinese English)
The phone cannot read the sim card and the IMEI number has disappeared. Following forum advice, I installed “mobileuncle” but cannot insert the IMEI number manually. When I go to Engineer mode, CDS information and try to go into Radio information, I get the message - “Unfortunately, Common Data Service has stopped.” So I cannot even go into Radio information.
I researched on the internet and tried to change the Rom. I installed the required version of TWRP recovery and after trying a few Roms, I managed to get Version VIBEUI_V2.0_1508_7.85.1_ST_A806 installed.
This version behaves better but still no IMEI number. Instead I get a different message – IMEI invalid.
When I try to call, I get this message: - “To place a call, first turn off Airplane mode”
But Airplane mode is off. But at least the dialer seems to be working and I am able to add contacts.
And I can get to radio information from mobileuncle with this version but when I type the IMEI number after the ST.., I get the message: “This command is not allowed in userbuild”
Even with a space between the ST and +, it still does not work and I get a different message, “at command is failed to send” I even rebooted after inserting the IMEI number and still no joy.
However, the wifi seems to be working on both above version and this.
I have a backup of the original corrupted rom so if anyone has a solution for either one, please help.
I installed the rom’s through TWRP recovery which is on my phone. I press volume and on/off buttons to enter into this.
I tried to install a flash tool and all the required drivers on my computer, I am using windows 10. I cannot seem to get the flash working.
Fixed
I managed to get the "SP Flash tool" working on my Windows 10 computer and that worked. Everything fixed. Thanks.
I recently tried installing this rom https://forum.xda-developers.com/vivo-5/development/rom-aosp-6-blu-vivo-5-clones-t3489281 but it did not work very well.
It is now appearing as invalid IMEI.
Any idea what I can try?
I've tried the MTK Droid tool, MAUI, SN Writer but none of them recognize the smartphone.
Try with this:
PD: Have you problems with WiFi?
For a temporal solution you can use MTK Engineering Mode (The Monster) from the Play Store. I think maybe you need to be rooted.
MTK settings
Connectivity
CDS information
Radio Information
you will see AT+, delete the plus , add the plus sign choose the first option (in my case AT+EGMR=1,7,"")
Put the your EMEI in between the comas "EMEI" if theres an error put a space between the + and EGMR
for the second EMEI select the second option AT+EGMR=1,10""
This will work until the phone is reset
