VikTormmm, So, let's, I will write here specifically for such questions.
Mini F.A.Q. About Android File System Device:
So. I will make a discovery for quite a "our little television viewers": the firmware of modern devices is a full operating system.
Android OS uses the following approach:
there is
system- It is in essence, and there is a "firmware". This is a system partition. It is she stitched. But (!) When loading the phone, the firmware is mounted only for reading. All changes are made to it only from recovery (all sorts of share, A la Root Explorer, and so on omit).
there is
data- This is the user section. It is here that all your apps, toys, and so on, all that you install on the "naked" phone are installed. And it is from here that they are removed. The system is not affected.
Of course there are / sdcard, / cache and other sections, but we will not sharpen attention on them.
What is the plus of this approach?
As many people already guessed - in the fact that you can safely update the firmware without affecting user data. While you do not make a full Wipe partition Data - all applications, all the settings and other from the "old" firmware will be saved. While you do not make Wipe Cache - even the installed MIUI theme and wallpapers will not fly!
The minus, of course, is also there - if you change the firmware to a completely different (for example, MIUI on CM) - Wipe Data is required. Otherwise, get a bunch of glitches. Of course, do not forget to make user data backup before changing the firmware.
Here, briefly, "for dummies," wrote.
