Difference of Rooting and Flashing: Meanings
Rooting and Flashing are two different operations to modify an Android phone, which you can tell from their meanings. Rooting refers to a process of attaining root access, in other word, administrative (superuser) permissions to an Android device so that you can remove the limitations that carriers and hardware manufacturers put on the device and have the ability to perform operations that are not allowed to a normal users, such as deleting system applications and settings, run specialized applications.
Flashing, to be specific, is flashing a ROM. ROM is a file containing executable instructions of an Android operation system and related apps. The stock ROM refers to Android version which is officially provided by mobile company along with the device; a custom ROM, on the other hand, is Android version that is customized and distributed by other developers. Flashing a ROM means installing a ROM on your phone so that the original Android OS can be changed and updated.
Difference of Rooting and Flashing: Uses
The Reasons of Rooting a Device
Why do so many users want to root their Android devices? Because only by rooting, they have the privilege to do things that is inaccessible to normal users: remove build-in apps that barely being used, install apps that is blocked by carriers, change keyboard, themes or other settings, add features like widgets in notification bar, speed up the device, improve battery life and more. If you need the above features to fit your personalized needs, you may want to think about getting your Android device rooted.
What especially worth mentioning is that there is a certain amount of users rooting their Android phones to flash a custom ROM. Though rooting is not necessary for flashing, but in some cases, when unlocking bootloader during flashing, root access is needed.
The Reasons of Flashing a Device
The reasons to root Android devices and the reasons why flashing a new ROM sometimes overlap. Some users flash a new ROM to modify the Android operation system of their smartphones, such as getting new features and customizations, removing bloatware, altering custom UI.
More users flash their Android phones to keep the devices up to date. The reality is that most phone manufacturers and carriers tend to focus on developing new phones while stop updating their older models. So the owners of these devices have to flash a custom ROM on their devices so that they can still enjoy the later versions of Android and have a new experience.
Other than that, if you want to unroot your phone or fix problems such as phone stuck during booting, system crash or instability, flashing a stock ROM to your device could be an effective solution.
