Rooting question

[laklaklak]

Hello all,

I am quite a noob with android rooting, but as I am geekier than the average user I want to get deeper.

As far as I can understand, rooting alone is of no use for the average user. Rather it is the first important step towards the installation of a new ROM that will give the user more control over his/her phone. The step sequence is:

1) Find a vulnerability -> exploit it (ROOTING complete) -> chmod /system to rw -> install custom recovery image -> install modified firmware update -> enjoy the phone!

or

2) Device in boot-loader mode and connected to PC -> issue command like "fastboot oem unlock" -> install modified firmware update -> enjoy the phone!

Number 2) does not require root, right?

Is the above correct or am I missing something / or misunderstood?

In case this is correct, does this mean that the important part is the remount of the /system partition?

Is rooting alone (without the image update) of any use?

Thank you!

First of all, what model phone are you using?

I wanted this question to be asked in general and not for a specific phone model. I just want to know about rooting and try to understand the "techniques" behind it.


PS. I own a Galaxy Ace.
