There are quite a number of reasons why your Mediatek device could not only be bricked but stay totally dead with no sign of life. In such a situation, pressing the power button will have no effect. This guide will briefly analyze each scenario and recommend fixes.
How to unbrick a dead Mediatek (MTK) device
Drained battery
The battery might be drained, causing the phone to appear bricked or totally dead. This is particularly rampant in Mediatek devices which have inbuilt batteries. Taking out and re-inserting the battery is a quick fix but in a case where the battery is inbuilt and you don't have the tools / skills to take it out then you need to keep charging the device
Interrupted flashing
If you interrupt any Mediatek flash tool then there's a very good chance that the device will go dead. This is the device stuck in Flash Mode. Interruptions could range from you accidentally shaking / removing the USB cord to the tool popping up an error message in the middle of a task. If you find yourself in this situation then its nothing to worry about, simply follow this guide
Flashing a wrong firmware
This is one of the most common causes of bricking on Mediatek devices. Just because you find a firmware for your phone model doesn't necessarily guarantee that it will work on your device without issues. Mediatek phones often have different variants / build numbers so its important you flash a firmware for your build. If this is what caused your phone to get bricked then downloading the right firmware and flashing it should help revive the device. Feel free to look through our Android firmware collection for a compatible stock rom
Flashing unsigned files / backed up firmware
Newer Mediatek devices which have features like Secure Boot get bricked when you flash an unsigned file to them (even a backup from another device of the same model). You''ll need a factory (signed) firmware to fix such devices
Join board points
In extreme cases where the desktop PC won't even detect the device despite having installed the right drivers (PC makes no sound and device manager doesn't refresh), you'll have to revert to soldering points on the motherboard to force a detection. We have more on this method over here so be sure to look it up if this best describes your current situation
