UMIDIGI A7 Pro: Repair IMEIs, MEID, TEE data and Google certificate
after full flash format or flashing an incompatible or badly assembled custom ROM




This guide is about how to repair your lost IMEI and MEID numbers and Google certificate on UMIDIGI A7 Pro with a special version of MediaTek SN Writer tool, using a PC running Windows 10 OS with administrator rights.

What you need:
  • Modify Windows hosts settings
  • VCOM drivers: Windows 10 can automatically install it. Please make sure that your Windows is logged in with administrator rights and your computer has a working internet connection when first time connecting your phone.
  • SN Writer TEE Tool with vturkey tool: SNWriter_1924-4.2.1-up-1.2.1-vturkey_A7Pro.rar





Let's get started step by step
(the driver installation process will be skipped in this tutorial since a Windows 10 PC connected to the internet can automatically install the compatible drivers)
You have to power off your phone before Step 8.!


  • Brows for the C:\Windows\System32\drivers\etc\hosts file and open it in a text editor.
    Add 116.62.230.138 pl.trustkernel.com to the end of the list of hosts, then save the hosts file. If you are not allowed to save it locally, first save it in an other location, then copy the new one by overwriting the original file.

  • Extract and open the folder of SNWriter_1924-4.2.1-up-1.2.1-vturkey_A7Pro, then run the application by double clicking SN Writer.exe.


  • Click the System Config button, then select all items that you can see checkmarked below. (MEID is present only in the 128GB version of A7 Pro, so just uncheck it if you have the 64GB version.)

    You may uncheck the IMEI and MEID Options and keep only one item (as your choice) selected in the Write Options if your only target is to recover your Google certificate and TEE data.


  • Click the Save button.


  • Enable AutoGen as shown on the picture below, then select the same items you selected on the System Config page except IMEI and MEID, since you need to enter your original IMEIs and MEID manually. Click OK. (BT and Wifi addresses will be auto generated)

  • Click the Start button.


  • In the pop-up window, enter your original(!) IMEI_1, IMEI_2 and MEID (only 128GB) numbers, then click OK.

  • Connect your (powered off) phone to USB, without pressing any button.


  • The writing process will start automatically while your phone is switching into META mode.

    Troubleshooting: If the process gets stuck at this point what the screenshot shows above (Start searching kernel...), disconnect the USB cable for a few seconds, then reconnect it and the process will continue. If the flashing process still fails, start again the flashing but leave your phone connected. Press and hold the power button until the flashing process starts, then release it.


  • After the writing process finished, you get the following screen (click Cancel), reporting the successful operation, and your phone automatically switches into charging mode.

Now you are DONE and may close SN Writer and power on your phone.
Congratulations!



In case of a bad connection, not properly installed drivers or if something other trouble happens, you get the following screen.

Check your USB cable, use another USB port, when the phone switched to META mode, check your Windows device manager to see if a new serial port is correctly installed.

After rebooting your phone, check the new IMEI and MEID numbers in Settings
About phone.

Thank you, bencebacsi
