¿What Is Root Acces On Android?

[XAMI]

 

We love Android, but rooting your phone can give you the opportunity to do so much more than your phone can do out of the box—whether it’s wireless tethering, speeding it up with overclocking, or customizing the look of your phone with themes.

 

Rooting, for those of you that don’t know, means giving yourself root permissions on your phone. It’s similar running programs as administrators in Windows, or running a command with sudo in Linux. With a rooted phone, you can run apps that require access to certain system settings, as well as flash custom ROMs to your phone, which add all sorts of extra features.

There are a ton of different Android phones out there, and while some rooting methods might work for multiple phones, there is no one-size-fits-all guide for rooting every phone out there.

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 SetCPU. 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.

• Stock: “Stock” refers to a few different things, depending on the context. When we refer to “Stock Android,” we mean the Google-built version you’d find on Nexus devices, with no extra UI chances like HTC Sense or Samsung TouchWiz. Many ROMs are based on stock Android with some additions, like CyanogenMod, while others are based on the version that came with your phone. In other cases, “Stock” can also mean the version of Android that came with your phone—e.g., if you want to get rid of your ROM and return your phone to factory settings, you might say you’re “going back to stock.”

• 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.

• 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.

• 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.

What’s the difference between rooting, unlocking, and flashing a ROM? 

This can be confusing, since the three practices are often performed at the same time. We’ve detailed some of this above, but briefly: Unlocking your bootloader is usually the first step in the process and allows you to flash a custom recovery. From there, you can then give yourself root access or flash a ROM. Root access isn’t required to flash a ROM, but almost all custom ROMs will come with root access built-in.

Is rooting illegal? 

No. Technically, it once was, but exceptions to the DCMA have made it legal for most phones (but not necessarily tablets). Either way, it’s hard to imagine anyone actually enforcing this rule.

Will rooting void my warranty? 

Yes. Unlocking your bootloader will void the warranty on your phone, even if your manufacturer provides a way for you to do it. That said, if you need warranty service for a hardware issue, you can sometimes unroot your phone and take it in for service with no one the wiser. However, some phones have a digital “switch” that flips when you unlock your phone that is very difficult or impossible to revert, so do your research before unlocking if you want to preserve your warranty.

Could rooting brick my phone? 

It’s possible, but pretty unlikely. As long as you follow instructions well, you probably won’t brick anything (but we’re not responsible yadda yadda yadda). Flashing custom kernels and radios is a little riskier than just rooting or flashing ROMs, but again, if you follow directions you should be okay. Keep in mind that bricking means your phone means it won’t turn on or function at all—if you’re stuck in a boot loop or boot straight to recovery, your phone is not bricked, and it can be fixed.

 

To be sincery, i prefer be root user, because when you buy a phone this come with app pre-installled, you can't delete these app and that occupies space in the phone, but when you are root user you can unistall these apps and much more.
