When an android device develops a kind of software malfunction, critical or minor, we may decide to flash the android device to correct the error however; the procedure for flashing android phones varies because of their varying hardwares.

To flash any kind of phone, you need flash files and in the case of Tecno android phones; the flash files are being extracted from a working identical Tecno phone.
For a successful flashing operation, the flash files must be exactly identical to the Tecno phone we wish to flash otherwise, the phone we are flashing may never come up again.

How Do We Determine Identical Tecno Android Phones?

So far, I have gathered four (4) variants of Tecno F7 and each of which are very identical by look but very different by components, including hardwares.

While trying to access the phones' components and pinpoint the difference or differences, whichever the case, I discovered ONLY one major difference; their boot.img files.

An identical Tecno F7 has the same boot.img file, both in size and nature as its counterpart. This fact holds true for all MTK androids.
For Example;
If you extract the boot.img file of 2 similar MTK android phone and they have the same size, maybe the same 4.9mb each then; they are identical.
Note that two similar phones may not be exactly identical.

How to Extract Boot.img File of MTK Androids

To extract the boot.img file of MTK androids, we would need to backup the whole STOCK ROM of the phone and so far, backing up any MTK android stock ROM would not have been possible if not with the help of the MTK Droid Tools.

MTK Droid Tools is a Windows program released by one of the XDA developers recently. The MTK Droid Tools has proven so useful recently.

Wait until MTK Droid Tools detects the phone. Once detected, you will notice that the colour on the lower-left of the program turns cyan-blue.
iii- Now, click on the Root, Backup Recovery tab of the MTK Droid Tools and click Backup to start the Full Backup.
iv- Wait for the Full Stock ROM backup process to complete. You can check for the backed up stock ROM on this folder: \mtkdroidtools\backups\the-mtk-phone-model-number. The folder is within MTK Droid Tools folder in short.
v- Just before the process completes, MTK Droid Tools would ask "Pack Up the Backup?". Select No and wait until Droid Tools display Task Complete.

Now, you have successfully backed up the stock ROM of your MTK android device.

To Determine Identical Phones
Now, to determine identical phones, backup as many as available phone of the same model and compare their boot.img file size.

To check the boot.img size, simply locate the folder where the backed up files are saved on your PC and open the folder for each phone. You should see a file named boot or boot.img, simply compare its size with others.
