* 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

If you accidentally bricked your MTK phone through whatever means then see:
How to Unbrick / fix a bricked Tecno phone
How to Unbrick / fix a bricked Gionee phone

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:

Tools needed

* Download SP Flash Tool
* PC
* USB Cord
* If you have access to a working phone of the same model then follow this guide @ //forum.hovatek.com/thread-468.html to make an MTK backup which should contain Preloader.bin and all other files you'll need
* If you don't have access to a working phone of the same model then download an MTK backup for your phone model @:

Tecno Stock ROMs
Gionee Stock ROMs
Infinix Stock ROMs
Opsson Stock ROMs

* If the MTK backup doesn't contain preloader.bin then download preloader.bin for your phone model ( Preloader.bin for Tecno phones only )


Procedure

* Using SP Flash Tool, flash the preloader.bin first (see SP Flash tool guide @ //forum.hovatek.com/thread-159.html ).
* 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.

We wont go into details about the function of the Preloader but one function - which you must've figured out by now - is that its what makes your Tecno phone boot. To fix the problem of a Corrupted Preloader, you'll need the following:

Tools needed
* A working Tecno phone of the same model
* Download PdaNet
* Download MTK Droid tools
* Download SP Flash Tool
* PC
* USB Cord

Procedure
* Important! Put aside any procedure you think you know because it obviously has not helped.
* Enable USB debugging on the good Tecno phone (Settings > Developer) then connect it to PC
* Install PdaNet on the PC with the USB debugging enabled working Tecno phone still connected
* At the end of PdaNet installation, you should get a "drivers successfully installed" message
* Launch MTK droid tools still with the working Tecno phone connected to PC
* MTK droid tools should detect and display the phones details by the left along with a yellow box at the bottom
* Click ROOT at the bottom of MTK and select Yes/OK if prompted on PC and Grant if prompted on phone
* A progress bar should load at the bottom shortly after which the yellow box should become green
* Click on the root,backup,recovery tab at the top
* Click Backup (MTK should keep writing some things by the right hand side during backup) and wait till backup is complete
* If you get a prompt to pack backup, select No.
* Once backup is complete, don't close MTK droid tools
* Go to the MTK droid tools folder > Backups > Folder named after the phone's model e.g Tecno_m3_backup.... and take note of this folder as the 'Backup folder' because we'll be referring to it soon
* Go back to MTK droid tools and click 'To prepare blocks for Flash Tool'
* A window will open, in this window, navigate to the Backup folder (mentioned above) and select the md5 file
* MTK will start copying some items (check the right hand side) so wait till copying is complete
* One copying is complete, open the Backup folder and you should see a folder named "!Files to flash"
* Open the "!Files to flash" folder and you should see a file named "preloader.bin" (right-click on the file and select properties to confirm) and it might have a VLC or any other media player icon
* Now that you have the correct preloader file (please forget any other one you think you have), disconnect the working Tecno phone
* Its now time to flash the preloader.bin file to the bricked Tecno phone using SP Flash Tool (see How to use SP Flash Tool)
* Using SP Flash Tool, flash the preloader.bin first.
* If flashing was successful then your phone should 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.

ok I have open sp flash tool and use your steps but after I hit F9 and download is complete my I tried to boot and its vibrate and not oped
