Note: This procedure is the same for all MTK Android phones (e.g Tecno, Gionee, Infinix, Opsson, Innjoo, TLC, Lead1 etc) but the backup files to be used differ
Some people; however, attempt unbricking / fixing their bricked MTK phones using either the wrong procedure or OS files. As a result, their devices get worse. The phones enter into a higher level of unbricking whereby, they don't even boot or charge any more, just dead. Even pressing the power button would have no effect in such a scenario. What has happened is called a corrupted or missing Preloader (preloader.bin).
We wont go into details about the function of the Preloader but one function - which you must've figured out by now - is that it helps make your MTK phone boot. To fix the problem of a Corrupted / missing Preloader, you'll need the following:

If flashing was successful then your phone should at least be able to vibrate when you press the power button or boot if the correct files are present on your phone; else, flash other necessary files to make the phone boot up and start working normally again
