UMIDIGI F1, F1 Play and S3 Pro: Repair IMEIs, MEID and Google certificate
after full flash format or flashing an incompatible or badly assembled custom ROM
Updated: 10th Feb 2020



This guide is about how to repair your lost IMEI numbers and Google certificate on UMIDIGI F1, F1 Play and S3 Pro with a special version of MediaTek SN Writer tool, using a PC running Windows 10 OS with administrator rights.

1.jpg



What you need:

EU versions:
EEA.jpg
Dual circle home button

Non EU versions:
nonEEA.jpg
Single circle home button


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 SNWrier_1828-4.0.0-vturkey, then open the application by double clicking SN Writer.exe.

  • Click the System Config button, then select all items that you can see checkmarked below.
    2.jpg
    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.

  • 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, since you need to enter your original IMEIs and MEID manually. (BT and Wifi addresses will be auto generated)
    3.jpg
    .
    .
  • Click the Start button.


  • In the pop-up window, enter your original(!) IMEI_1, IMEI_2 and MEID numbers, then click OK.
    4.jpg
    .
    .
  • Connect your (powered off) phone to USB, without pressing any buton.
    The writing process will start automatically while your phone is switching into META mode.
    5.jpg
    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, reporting the successful operation, and your phone automatically switches into charging mode.
6.jpg
Now you are DONE and may 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 reboot your phone, check the new IMEI and MEID numbers in Settings --> System --> Advanced --> About phone.



All the screenshots are captured and the guide is written by me for UMIDIGI users. Unauthorized copy of this content is prohibited. Please let me know if you find errors or missing info.
Thank you, bencebacsi

THANK YOU for this thread.
I tried it about ten times and it didn't work.
Always got this annoying "TEE PL failed with -19"-message (like others here too). Don't know what this means. But then I looked for another SN-Writer-version and so I installed the latest one (v1.1916.00) and SURPRISE...suddenly it worked and I could read "PASS", yeah.
Now I can see my real IMEI again on my phone but the red annoying Tee and Google text is still on my screen.
Asking myself if it's due to missing one number in my MEID (it just has 14 instead of 15 numbers because you just can insert 14 with SN-Writer).

So next step: Get rid off this horrible big letters and don't stop trying...
Wish me luck! ;)

Put only the first 14 characters in. The 15 character is a check digit and you don't need to put in. Later when you restored you MEID you gonna see you have again the same 15 characters.

Hello. before, I could manage to change IMEI by secret codes such as *#*#08#*#* . but I can't change on my new F1 Play ( non eu version ). This secret code works out,it opens the page where I can write down the IMEI numbers.  but although I save and it says that it succesfully change the IMEI, it doesn't change in fact. Do you know any other way for F1 play to change IMEI without programme but through secret codes?
