Most phones ship with a locked bootloader, and you need to unlock it before you're able to overwrite the system files. A custom recovery is normally installed when you root. This is a small piece of software that is used to create a backup and to flash a ROM. For the purposes of this guide, we're going to assume you've got all these things in place already. You need to do a little bit of prep work before you can get started. One takes the manual approach, the other uses an Android app. In this guide, we'll take a look at two ways to flash a custom ROM.
