What is Bootloader?

According to Google “A bootloader is a vendor-proprietary image responsible for bringing up the kernel on a device. It guards the device state and is responsible for initializing the Trusted Execution Environment (TEE) and binding its root of trust”. Confused? So am I! let us leave all this aside.

In simpler terms, a Bootloader is a software that runs every time your phone boots (start). It contains a set of instructions that tells the device which program to load at what instance. It also decides whether to boot your device to ‘Android OS’ or to the ‘recovery mode’. Consider it a gateway, leading towards a road having all directions in technical jargon. hence, if you aren’t comfortable with the technical terms, you may get ‘lost’ in the way (if that happens, just remember us!).

Downsides of Unlocking the Bootloader

The biggest downside of unlocking the bootloader is that the warranty of your device would be void. But why do the manufacturers do this? The answer is simple. All the OEMs ship their devices with a locked bootloader so that the users could only use the stock OS that comes pre-installed.

The device vendors do not want the users to try out the customized version of the OS as they are launched by third-party sources such as LineageOS or Resurrection Remix. The manufacturers are in no way related to these creators, hence they distance themselves by voiding the warranty of the device.
