Reviving a device from the dead

Sometimes, something unexpected happens, and you end up breaking a device, making it no longer boot.
This is what we call "Bricking", and we call it that because at that point your device is a fancy colorful brick

Though, sometimes there's ways to rescue your device and bring it back from the dead, so that will be detailled here

Saving yourself from a "Soft Brick"

So first, what is a "Soft Brick"?
A Soft Brick is when you break the device on a software level, like for example flashing a wrong ROM from another device, but critical components like the Bootloader still works

You can usually save yourself like this:

• Connect your device to your PC
• Install Fastboot (see: ADB and Fastboot)
• Download a full firmware image for your device
• follow it's flashing instructions
• Congratulations, you should now be back on the Stock ROM and can try again

Saving yourself from a "Hard Brick"

A "Hard Brick", unlike a Soft Brick, is when your device is missing critical system components, like the Bootloader, or on MTK devices the Preloader.

Usually, there's no ways to recover from this, I would check the XDA Forums for your device.
