How to Flash a Custom ROM on the HTC One Max

A custom ROM is a custom version of Android for your device. After you have rooted your device and flashed a custom recovery on it, you can then use the recovery to flash a custom ROM. Thanks to a sizeable community of developers, there are a lot of these third-party ROMs to choose from (depending on the device) and each one is unique. Developers usually give you the latest version of Android in their ROM, their own custom themes, options, and a ton of other customization options and enhancements.
