Glossary of Rooting Terms
As you learn more about the rooting process, you'll probably run into a bunch of terms that can be confusing. Here are some of the most important ones and what they mean.
Root:
Rooting means you have root access to your device—that is, it can run the sudo command, and has enhanced privileges allowing it to run apps like Wireless Tether or
set CPU. You can root either by installing the Superuser application or by flashing a custom ROM that includes root access.
ROM:
A ROM is a modified version of Android. It may contain extra features, a different look, speed enhancements, or even
a version of Android that hasn't been released for your phone yet. We won't discuss ROMs in depth here
Kernel:
A kernel is the component of your operating system that manages communications between your software and hardware. There are a lot of custom kernels out there for most phones, many of which can speed up your phone and increase your battery life, among other things. Be careful with kernels, though, as a bad one can cause serious problems with your phone and possibly even brick it.
Radio:
Radios are part of your phone's firmware. Your radio controls your cellular data, GPS, Wi-Fi, and other things like that. You can sometimes find custom radios for your phone that you can flash yourself, but beware as sometimes these can cause problems.
Flash:
Flashing essentially means installing something on your device, whether it be a ROM, a kernel, or a recovery (see below) that comes in the form of a ZIP file. Sometimes the rooting process requires flashing a ZIP file, sometimes it doesn't.
Brick:
To brick your phone is to break it during flashing or other acts. There is always a small risk with flashing, and if your phone becomes unable to function—that is, it basically becomes a brick—you've bricked your phone. The risk is very small, however, and more often than not people say "brick" when they really mean "it turns on but doesn't boot properly," which is a very fixable problem. See the FAQ for more information.
Bootloader:
Your bootloader is the lowest level of software on your phone, running all the code that's necessary to start your operating system. Most bootloaders come locked, meaning you can't flash custom recoveries or ROMs. Unlocking your bootloader doesn't root your phone directly, but it does allow you to root and/or flash custom ROMs if you so desire.
Recovery:
Your recovery is the software on your phone that lets you make backups, flash ROMs, and perform other system-level tasks. The default recovery on your phone can't do much, but you can flash a custom recovery—like ClockworkMod or TWRP—after you've unlocked your bootloader that will give you much more control over your device. This is often an integral part of the rooting process.
Nandroid:
From most third-party recovery modules, you can make backups of your phone called nandroid backups. It's essentially a system image of your phone: Everything exactly how it is right now. That way, if you flash something that breaks your phone, you can just flash back to your most recent nandroid backup to return everything to normal. This is different from using an app like Titanium Backup that just backs up apps and/or settings—nandroid backups backup the entire system as one image. Titanium backups are best when switching between ROMs or phones.
