Restore Fix Lost IMEI and Serial Numbers for MTK6582, MTK6572, MTK6592, MTK6589, MTK6595

After flashing ROMs or installing updates, it is possible that the phone will get an invalid IMEI or unknown baseband. Invalid IMEI would mean no mobile network connections.

This tutorial will help you restore / fix lost / missing IMEI and Serial Numbers for MT6582, MT6572, MT6592, MT6589, MT6595

One method of restoring/repairing an invalid IMEI or unknown baseband is outlined in this tutorial. If this method does not work, you may try using MTK Droid Tools to manually enter IMEI numbers.

If these methods fail, check to see if you have a valid Serial Number.

1
. From your phone keypad, type in *[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذا الرابط]#.

2.
Tap on SN. If it shows a blank space, that means you would first have to restore your Serial Number before you can work on fixing the IMEI
.

1. Extract and install Maui META Software. Do not launch the program yet.

2. Switch your phone on and connect it to your PC. Install MediaTek VCOM Drivers.

3. Disconnect your phone and turn it off.

4. Keeping Device Manager open and visible in the background, locate MauiMETA Program and Run as Administrator.

5. Click on Options in the menu bar, and select “Connect Smart phone into META mode”

6
. Click on Reconnect. Maui META will now ask you to “Please connect cable to target and then power on”
.

7.
Connect your phone to the PC, but DO NOT turn it on. Maui META will trigger the power up sequence. You should hear about 2 connect-disconnect sequence sounds from your PC.

a. During the first connection to Maui META, your phone will boot partially while CDC VCOM Drivers are installed automatically. Wait for it to finish.

b. After successful installation, you should see “Gadget CDC VCOM Driver (COMxx)” in Device Manager.

c. Even if the installation was successful, Maui META may still be unable to connect to your phone. If this is the case, close Maui META and disconnect your phone. Shut your phone off manually.

d. Run Maui META as administrator again and repeat step 5 to 7 and proceed to step 8.

8. Check if the connection was successful.

It is successful if you see the following:

If the connection was successful, proceed to step 9. However, f your phone shows as a MediaTek Preloader in Device Manager, or if your phone starts charging via USB, follow the steps below.

a. Go to Device Manager, highlight your phone in the list and right-click on it. Choose to update drivers manually, then point to this folder:  (D:\…\MTK_USB_ADB_Ultimate\All MTK USB Driver 2014 Properties)

b. Disconnect your phone, and repeat steps 5 to 8.

c. If you are continuously returning to these sub-steps, try using a different USB port.

(note: If your phone is not showing in Device Manager at all, uninstall drivers. Download USBdeview software, Run as Administrator, then uninstall your phone’s Device IDs. Restart at step 2.)

9. Once your phone boots into META mode, a Get Version pop up window will appear. Ignore and close this window.
