What is Rooting?
“Rooting” your device means
obtaining “superuser” rights and
permissions to your Android’s
software. With these elevated user
privileges, you gain the ability to load
custom software (ROM’s), install
custom themes, increase
performance, increase battery life, and
the ability to install software that
would otherwise cost extra money
(ex: WiFi tethering). Rooting is
essentially “hacking” your Android
device. In the iPhone world, this
would be the equivalent to
“Jailbreaking” your phone.
Why is it called Rooting?
The term “root” comes from the Unix/
Linux world and is used to describe a
user who has “superuser” rights or
permissions to all the files and
programs in the software OS
(Operating System). The root user,
because they have “superuser”
privileges, can essentially change or
modify any of the software code on
the device. You see, your phone
manufacturer/carrier only gives you
“guest” privileges when you purchase
your device. They do this for good
reason… they don’t want you getting
into certain parts of the software on
your phone and screwing it up
beyond repair. It makes it much easier
for them to manage and update the
devices if they lock it all down. This
way, all the users are running the
same unmodified version of the
phone’s software. This makes it much
easier for them to support the
devices. But, for the tech-savvy crowd,
only having “guest” privileges on your
device is pretty lame and it locks down
a lot of potentially useful features.
