3. Rooting v. Unlocking
Rooting = superuser/admin permissions, you can change the OS.
Unlocking (your bootloader) lets you install custom ROMs, replacing your OS (normally stored in Read-Only Memory).
Bootloader: Android contains several partitions, one with system files and another with your accumulating app data. This is like a security checkpoint for all those partitions, ensuring your software is genuine and telling your phone where to look to get running.

4. Cons Device may be insecure Risk of bricking your phone
Possible warranty voiding (not in EU?)
Battery life problems, hardware issues, bugs
... just google/check XDA-Developers.com beforehand : )

6. Great, I’m in! What’s next?
Find a YouTube video/tutorial that shows how to work with your device. In it they’ll give you links to a few things you need to get:
Android SDK (Recovery software: TWRP)
Custom Google Apps (OpenGAapps pico)
BETA-SuperSU (allows for advanced management of Superuser rights for all your apps that need root access )
Possibly Custom ROM (eg: CyanogenMod, Paranoid Android: get “latest release”, not “nightly”)

7. Final steps
MD5 check! The md5sum is used to verify the integrity of files: any change to a file will also change its MD5 hash

8. Now you’re ready
Make sure your laptop and cellphone are fully charged, and that you have a cable to connect the two. Read over all the instructions very carefully before you proceed; download everything and prepare it in advance. Don’t do it before anything important; I usually gear up anticipating a few-day campout by my phone (Christmas!)
