Bootloaders and the Very Basics of Android Hacking
The Very Core of Android Customization
One of the core principles of the mobile OS is that you can basically do anything with it, which includes ‘rooting’ and the installation of custom ROMs. Although it may in some cases void the warranty, users like to fiddle around with their devices for a variety of reasons. Many manufacturers like to load up their Android devices with a custom overlay, of which HTC Sense is a good example, and some users want to use a different version altogether. Others just want to improve on what is offered and some want to be able to overclock or undervolt their hardware.
Whatever the purpose, getting your Android device to play nice with customization will require the ‘bootloader’ to be unlocked. We explain what the bootloader is, how it behaves and what the consequences are of a locked down bootloader, which is the case with some devices.
