How to check bootloader status in any Android device

If you are an Android device user, then you possibly would have heard the term ‘bootloader’ for sure. However, if you still are unaware due to any reason, then you should know that bootloader is a code which executes before any operating system starts to run in any device. Most of the times, if you are an Android lover who even likes to customize his device according to his will, then there is very likely that you would want to unlock the bootloader of your Android device. However, if you are looking for a way to check bootloader status in any Android device, then here is a solution for you.

Most of the times, the manufacturers would just sell their devices with the bootloader locked, which doesn’t let you install a custom ROM or any other software which you aren’t officially allowed to install or install additional firmware on your devices. This means that doing anything like installing new firmware, new custom ROM or flashing anything new, you actually would have to unlock the bootloader of your current Android device.

However, yes, the thing about unlocking bootloader of any Android device is that once you unlock the bootloader, there is no going back and well, you would even void the warranty of your Android device. So, please be sure about what you are actually doing.

For a few devices, we have already mentioned guides and well, you can check them out here.
