Quite a number of MTK users have been having this issue on their MTK devices after flashing one ROM or another; something i call the 'Custom ROM fever'. This issue is mostly caused by wiping / corruption of the data partition. The Baseband and radio (for network signal) are controlled by the NVRAM (located in data/nvram/md/NVRAM/NVD_IMEI) and a file called MP0B_001. Once this file is missing or the NVRAM partiton is corrupted, your phone's IMEI and radio functionality cease to exist. There are several methods to fix this:

+ Go to Settings > About and check Baseband. If it says Unknown then flash the Stock MTK backup using Sp flash tool - to regain Baseband

MP0B_001 Method
1. Download ROM toolbox lite from Playstore
2. Download IMEI.zip (to create a new IMEI file) then unzip the content of the folder (imei.exe) to a folder on your desktop
3. In command prompt, navigate to the imei.exe containing folder you just created on your desktop
* NOTE cd\ then enter (returns to root directory

Code:

cd.. enter (goes up one directory)

Code:

cd foldername enter (navigates to a folder called foldername)

4. A faster method is to open the imei.exe containing folder > Hold down Shift > Right-click on an empty space > Select "Open Command Window here"
5. When you're inside the imei folder in command prompt, type imei.exe <15digit_IMEI_1> <15digit_IMEI_2>

Code:

imei.exe 123456789111111 123456789111124

6. Press Enter
7. If both IMEIs you gave are of the correct format, a file named MP0B_001_NEW will be created. Rename it MP0B_001.
8. Now you can send it to the sd of your phone
9. Install ROM toolbox lite then go to root explorer
10. In root explorer, delete the existing MP0B_001 file (located @ device/data/nvram/md/NVRAM/NVD_IMEI) and replace with the one you just created
11. Long press the new MP0B_001, go to permissions and tick all 9 boxes at the top then select ok (don't tick special pernissions)
12. Restart your phone
13. Your SIMs should be detected, IMEI reflect and Baseband version change from unknown to what it should be. * Note that getting this done might not be this direct due to different scenarios but replacing the MP0B_001 file is the ultimate goal in order to fix the issue.

IMEI Replacement Method
This method involves the use of MTK droid tools and is only applicable when your SIM cards are detected but IMEI is invalid or null. To do this:
1. Download MTK droid tools
2. Download PdaNet
3. Enable USB debugging on the phone then connect it to the PC (don't enable mass storage)
4. Install PdaNet on the PC with the phone connected; you should get a message saying drivers installed successfully.
5. Extract then launch MTK droid tools on the PC (still with phone connected to PC)
6. MTK droid tools should detect and display your phones details
7. Click on IMEI/NVRAM
8. Supply the IMEI(s) then click replace
9. Restart your phone if it isn't automatically restarted
10. Your IMEI issue should have been resolved -

NVRAM Restore Method
* Note that you need a working phone of the same model to backup NVRAM first
1. Download MTK droid tools
2. Download PdaNet
3. Enable USB debugging on the GOOD phone then connect it to the PC (don't enable mass storage)
4. Install PdaNet on the PC with the phone connected; you should get a message saying drivers installed successfully.
5. Extract then launch MTK droid tools on the PC (still with phone connected to PC)
6. MTK droid tools should detect and display your phones details
7. Click IMEI / NVRAM
8. Click Backup
9. When backup is complete, open the MTK Folder > BackupNVRAM to confirm that backup was successful 8. Connect the phone with Basebrand / IMEI error to the PC still with MTK droid tools open 9. Still under IMEI / NVRAM, click Restore
10. Select the appropriate files from the windows that pop up
11. Reboot the phone once the procedure is complete

Engineering Mode Method
1. Download and Install Mobile Uncle then grant superuser permission
2. Select Engineer mode
3. Select Engineer mode (MTK)
4. Navigate to the Connectivity tab
5. Select CDS information 3. Select Radio Information
4. At Phone 1: Insert the command below then click Send at command

Code:

AT+EGMR=1,7,"IMEI1"

5. At Phone 2: Insert the command below then click Send at command

Code:

AT+EGMR=1,10,"IMEI2"

5a. If you get an error like "This command is not allowed in user build" then leave a space between AT+ and EGMR as show below

Code:

AT+ EGMR=The rest of the code

6. Go back to Mobile uncle home screen
7. Click on Engineer Mode
8. Select Engineer mode (Android)
9, Select Phone information
10. Click Turn on radio

All Credits Goes to HovaTek Forum and i tested each method and every one of them work on certain phone depends on the phone but most of the phones repaired using MP0B_001 Method

And Most Of MTK Phone Lose imei When You Format it Using SP Tool Most Of Phones stuck on Logo Only Need Flash Only and After You Flash Make Sure You Wipe The Phone FRom Recovery

Any Questions Please Post and i will be Happy To Help You
