This guide is about how to repair your lost IMEI numbers with MediaTek SN Writer tool. This tool is compatible only with MTK SoC based devices, like MT6592, MT6752, MT6753, MT6735, MT6755 etc.

You might lose your IMEI numbers by accidentally formatting the flash chip or by installing an incompatible ROM.



What you need:


Let's get started step by step (the driver installation process will be skipped in this tutorial)
You have to power off your phone before Step 10.!


1. Extract and open the folder of SN Writer, then open the application by double clicking SN_Writer.exe.

2. Set ComPort to USB VCOM and Target Type to Smart Phone (as it's shown on the picture below).

3. Click on the System Config button, then select all items that you can see checked below.

4. Load the Modem_1 database file (click on MD1_DB button) located in the stock firmware folder.

Note: You have to use the database files of the same version of ROM you have installed on your phone!

5. Load the AP database file (click on AP_DB button)

Select the file without 'ENUM' at the end if you have two similar files.

6. Click on Save button.

7. Enable AutoGen as shown on the picture below. (BT and Wifi addresses will be auto generated)

8. Click on Start button.

9. In the pop-up window set your original(!) IMEI_1 and IMEI_2 numbers, then click OK.

10.  Connect your (powered off) phone to USB. - You need or don't need to press any button while connecting, depending on your model. Only one configuration will work! You have to apply the same method that's needed for SP Falsh Tool as well. In most cases you don't have to and musn't press any button.
The writing process will start automatically while your phone is switching into META mode.

NOTE: 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.

11. After the writing process finished, you get the following screen, reporting the successful process, and your phone automatically switches into charging mode.

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

In the case of bad connection, not properly installed drivers, you loaded incompatible DB files 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.
At some devices (UMi eMAX for example) the NVRAM partition is write protected. In that case you have to format the NVRAM partition or the whole flash chip to be able to use this tool.

After reboot your phone, check the new IMEI numbers by dialing *#06#


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

The connection seems to be okay now, but the loaded DB files might be incompatible for some reason. There are 3 different SPFT ROMs available in the ROM section. I suggest you to try all of them if needed.

My Umi Super can't connect to the SN Writer Tool the same as in the Flashtool, in the flashtool i plug it off without pressing anything and the flashtool detects it and start working, but when i plug it that way with the SN Writer tool, it don't detect it cause my phone enters in charging mode, i've tried connecting it with volume + but can't make it work.

Any suggestions? Thanks!

Unfortunately, your attached pics cannot be downloaded.You shouldn't have 2 pcs. APDB files. One of them might be in the ROM folder mistakenly. Which ROM do you use?

Do you have missing or null (all zero) IMEI numbers? As I've written, this tool is not able to replace working IMEIs.

Them IMEI took  from the box of Umi Iron, using the files in ROM Y900_UMI_V1.7_20151020_1711 that you provided in the forum, inside there are 2 APDB:
APDB_MT6735_S01_L1.MP3_W15.40
APDB_MT6735_S01_L1.MP3_W15.40_ENUM

I lost all 2 imeis after flashing iron to erase the privacy password malware.

The v1.7 is a beta release. Use the v1.5 instead. That's okay if you use your original IMEI numbers, but have you lost them in your phone?

And, have you really lost the IMEIs? Did you checked them by dialing the *#06# code?
