How to flash an MTK device using SP Flash Tool
With low-end, I don't exactly mean those phones with those slipshod finishes, and screens which crack in a few days. These processors even power the cheaper Lenovo, Sony and Oppo devices, and they are definitely NOT of such kind.
The moment a person like me thinks of these brands, probably he will remember Custom recoveries, ROM's etc. First, you root your device, flash a custom recovery, and then a custom ROM. When you do all this, you run a real chance of bricking your device.
Bricking-sounds rather ghoulish, right? When you brick your device, you lose all your data, including the Android OS itself. So the only solution is to reinstall the OS again, or, technically, flashing the device.
Flashing MediaTek devices is pretty straightforward, if you have the firmware for your device. If you don't, search for the firmware on Google, or better still, on XDA. You will probably get it.
All that you need for this process is a computer[running Windows or Linux], your bricked MTK device, and a working USB cable.
Steps for Flashing
- Initially, extract the contents of the firmware zip that you have downloaded on your computer . This may take a minute or so, at the most.
- After this is done, check out whether the SP Flash Tool has been included. Otherwise, download it from this site: http://spflashtool.com/
- Also download the MediaTek USB VCOM driver from the same website and install it.
- Now open the SP Flash Tool. It'll look something like this.
- Now select the Scatter Loading file. It will be in the Firmware folder, with the form [MTxxxx_Android_scatter.txt]. 'xxxx' here corresponds to the model number.
- Unless you are interested, don't change any of the other advanced settings.
- At this point, your mobile device comes to play. Switch off your device, and if possible remove the battery as well. If the battery is on, ensure that there is atleast 60-70% of charge on it.
- Click on the Download button.
- After this, connect your device to your computer, preferably with the USB cable that came with the device. If your device switches on and starts charging, press the power button till the screen switches off.
- The flashing process can take a few minutes. Chances are that your computer may hang, but don't do anything. It may cause more harm than good.
- If the flash is successful, you'll see a pop-up, with a tick mark enclosed in a green circle. The window's title will probably be 'Flash OK!' If there is any error, retry the process.
