Is my rooted android the reason my sytem update keeps failing?

Q. My husband rooted my phone. I don't know what it does. I don't even use it and now I keep trying to do a system update and it fails. I can't call Verizon because I have a rooted phone. Help!

A. Restore to the stock Android firmware.

By the way, rooting is a process allowing users of mobile phones, tablet PCs, and other devices running the Android operating system to attain privileged control (known as "root access") within Android's subsystem. Rooting is often performed with the goal of overcoming limitations that carriers and hardware manufacturers put on some devices, resulting in the ability to alter or replace system applications and settings, run specialized apps that require administrator-level permissions, or perform other operations that are otherwise inaccessible to a normal Android user. Rooting is analogous to jailbreaking devices running the Apple iOS operating system or the Sony PlayStation 3. On Android, rooting can also facilitate the complete removal and replacement of the device's operating system.

As Android was derived from the Linux kernel, rooting an Android device is similar in practice to accessing administrative permissions on Linux or any other Unix-like computer such as FreeBSD or OS X.

Description
Most devices running Android must be rooted in order to install custom versions of the Android system such as CyanogenMod. The stock configuration (unrooted), user-installed applications do not have direct access to the flash memory chip on the device and are not able to replace or modify the operating system itself. Rooting is also necessary for certain applications and widgets that require additional system and hardware rights such as rebooting the phone, certain backup utilities, and other access to other hardware such as status LEDs. Rooting is also needed to disable or remove manufacturer-installed applications such as City ID. Rooting the phone typically also includes installing an application called Superuser that supervises which applications are granted root rights.
In contrast to iOS jailbreaking, rooting is not needed to run applications not distributed by the official Android Market (sometimes referred to as "sideloading"). However some carriers, like AT&T, prevent the installation of applications not on the Android Market in firmware,[2] although the Samsung Infuse 4G from AT&T allows running applications not downloaded from the market.[3]
As of 2012 the Amazon Kindle Fire is locked to the Amazon app store instead of the Android market, and other vendors of Android devices may lock to other sources in the future. Access to alternate apps may require rooting but rooting is not always necessary. As an example, for the Kindle fire it is possible to load the "easy installer" app from the Amazon app store and then use it to "sideload" apps from any source.
One of the potential downsides to rooting is some phone makers consider it to be "modifying" the phone, which may void the warranty. However, if the phone is un-rooted before the user tries to use his or her warranty, there is no easy way for the warranty provider to know that the phone was previously rooted. The term "bricking" is used to describe a device which has had its software modified improperly to the point where it is no longer functioning.[4]

Process
The process of rooting varies widely by device. It usually includes exploiting a security weakness in the firmware shipped from the factory. For example, shortly after the T-Mobile G1 was released it was quickly discovered that anything typed using the keyboard was being interpreted as a command in a privileged (root) shell. Although Google quickly released a patch to fix this, a signed image of the old firmware was leaked giving people the ability to downgrade and use the original exploit to gain root access. Once this exploit is found, a custom recovery image that does not check the digital signature of a firmware update package can be flashed. In turn, using the custom recovery, a modified firmware update can be installed that typically includes the utilities (for example the Superuser app) needed to run apps as root.
The Google-branded Android devices, the Nexus One, Nexus S and the Galaxy Nexus, can have their boot-loaders unlocked by simply running the command "fastboot oem unlock" from a computer connected to the device while it is in boot-loader mode.[5] After accepting a warning the boot-loader will be unlocked so that a new system image can be written directly to flash without the need for an exploit.
Recently, Motorola, LG Electronics and HTC Corporation have added security features to their devices at the hardware level in an attempt to prevent retail Android devices from being rooted. For instance, the Motorola Droid X has a security boot-loader that will put the phone in "recovery mode" if unsigned firmware is loaded onto the device.
