What is root and rooting?

When someone does any procedure in an Android device as a root, it means that the user can have access to the operating system with administrator privileges.

What is an IMEI address?

IMEI is an acronym that means International Mobile Equipment Identity. It is the identification number that the manufacturer gives to a device, which is unique and it is useful for warranty purposes, technical support, being able to be blocked in case of being stolen, or to request a carrier change.

Why is the IMEI address so important?

Your Android smartphone´s IMEI address is also related to the device´s security.

In case that the device is stolen, you need to report it and give the number to the authorities and the carrier so that they can block it and make the appropriate follow-up.

It is also important to know the device´s IMEI address number to reset it in case that it gets deleted while modifying a custom ROM file (a file of the operating system) or something similar.
