Rooting and Stuff... (Easiest by the way)

Ok Ok Ok Soo...  This Is by Far The Most Easy Way to Root This Device

The First and easiest way to do this (and it's also for your own good) is to upgrade to the Latest Firm (4.1.2)

So here is the Easiest way to do it... ;) 

• If you run Gingerbread, start from A directly
• If you run un-rooted Jellybean, start from B
• If you run rooted Jelly Bean without a custom kernel, start from B, but skip number 1 and 6.

Note that Rooting may Damage your phone (Nah Not really.. well it has never happened to me before at least) However let it be Clear that I DO NOT TAKE ANY RESPONSIBILITY OF ANY MISHAP TO YOUR BELOVED S ADVANCE

Let's Get Started Then ;)

This shall guide you through turning your suckish (No Offense) GB i9070 (not i9070p) to JB Awesomeness.
Unless your phone shipped from Russia, it has Gingerbread preinstalled... so, let's first Jellybeanize it.



A) JELLYBEANIZATION:
This shall guide you through turning your suckish (No Offense) GB i9070 (not i9070p) to JB Awesomeness.
Unless your phone shipped from Russia, it has Gingerbread preinstalled... so, let's first Jellybeanize it.

1. Download Odin3 from  Here. Extract it into a folder.
2. Download Stock JB firmware from  Here . Extract it into a separate folder, you will get a .tar.md5 file.
3. Make sure you have Kies installed, but not running.
4. Turn your phone off, and boot into Download mode, this can be done by holding the Vol.Down+Home+Power buttons together at the same time, till it boots.
5. Press Volume up to continue. Plug in your phone (make sure it's at least 60% charged) . Wait till Odin recognizes (It should say something like COM:PORT... to the left).
6. Click on PDA and choose the firmware (.tar.md5) that you extracted in step 2. Click start.
7. Right now, a virus which will fry your phone's internals is being installed... Calm down, joke.
8. When your phone boots into JB, and Odin says "PASS". Unplug.

NOTE: There is a chance that you will get a bootloop ( i.e. Android won't boot ). No, no, no... your phone isn't broken! Simply reboot to stock recovery by powering off, then pressing Vol.Up+Home+Power buttons together and wipe data/factory reset. It'll boot nicely
Now, you are currently on a stock Samsung Jellybean firmware, which is not rooted. This basically means that you do not have access to modifying the system files in your ROM, which means that you cannot install any custom kernel, custom recovery or a custom ROM... In section B, you will learn how to gain root access, install a custom kernel with a custom recovery.

B) ROOTING, KERNEL & TWRP/CWM:
Now, you are currently on a stock Samsung Jellybean firmware, which is not rooted. This basically means that you do not have access to modifying the system files in your ROM, which means that you cannot install any custom kernel, custom recovery or a custom ROM... In section B, you will learn how to gain root access, install a custom kernel with a custom recovery. 

1. Download Shaan's root from Here
2. Download Temporary cwm from  Here
3. Download CoCore + TWRP (TWRP is one of the two recoveries available, we will use it in this guide because it looks less intimidating, and it's touch-enabled ) from Here
4. Place all 3(or 2 if you're rooted) zip files in your external SD card
5. Power off. Boot into recovery by holding Vol.Up+Home+Power.
6. By navigating via volume buttons, choose install zip from external sd card, and install root.zip... shouldn't take long.
7. In the same way install update.zip. Now in a few seconds, you will get a different screen, this is Clockworkmod recovery, albeit a temporary one..
8. In this recovery, go to install zip, then install zip from external sd, and choose CoCore+TWRP. After installation, keep going back until the main cwm screen, and hit reboot.

Now, you are rooted, with a custom kernel, and TWRP ( a custom recovery). You can either stay on stock Samsung firmware. Or get a Custom Rom Check my other Post for that
Hopefully this guide was useful for you...

NOW, Everytime you boot into recovery (which is the way to backing up and installing custom ROMs) you will get TWRP.

This is basically it for this tutorial! Finally eh? But really now, all the above is very very easy once you get used to it, I mean, all the sections in the guide, A, and B can all be done in 5 minutes, but I've simplified everything as to suite everyone's experience.
