ClockworkMod Recovery, generally shortened to “CWM”, is one of the most popular custom recoveries for Android-powered smartphones and tablets.

What are Images?
No, we’re not talking about pretty pictures that are worth a thousand words, in this context an “image” is essentially a self-contained operating system. Most of us are familiar with the “System” image, it’s the part of Android that we use every day. There is also another image, the Recovery image, that most users only see when they’re installing an over-the-air (OTA) update, and then it’s only seen for a minute or so. Power users, like you and I, can use the Recovery image for all sorts of things: advanced recovery, backups, restorations, and maintenance. With it was can flash custom ROMs and kernels, which are some of the most common reasons for installing CWM. What all can be done and what does it all look like? Let’s take a look!
