So rooteo process changes depending on which version you are, so make sure you know which version you have before you get to it.

We thus: Go to Settings> Applications> Development and check the USB debugging box. Connect your phone to the PC via microUSB. Download this file, unzip it and you will see a folder (files) and file (runme.bat). Make sure you have the drivers for your Galaxy S2 properly installed before proceeding with the procedure.

How to rooting Samsung Galaxy S2 GT-i9100 Android 4.0.x Ice Cream Sandwich In principle, the above method should work fine, as is also true for this release. If it were not so, we will post another method called FramaRoot, rather used a program which we discussed in another tutorial rooteo. The procedure is very simple: Download the program from here. We installed it in our Galaxy 2 having previously copied. Apk in its internal memory. Open FramaRoot.

In case you do not wish or do not work, you can always rooting your phone by this other method, though, for me, is a little heavier but still easy to do. Rootearlo is through ODIN, a program widely used in this development environment. Carefully follow the steps if you want to have a problem: Make sure you have installed the drivers for your Samsung Galaxy S2 GT-i9100 on your computer. The best thing to do is download the Samsung Kies and so you avoid hassles. Download this file and extract its contents. Download ODIN v1.85 and unzip the folder. Turn your phone off completely. Now let’s turn it into Download Mode, for which will press the Volume Down button + Home + Power button at the same time, being the last we press Power. Wait till you see the Android robot and a triangle. Press Power to confirm be entering Download Mode. Open ODIN on your computer and connect your phone while in Download Mode.

Take a few minutes away, so do not fret. When the process is complete, your phone will reboot. Remove the cable when you see the home screen. Make sure you have root access to SuperSU. Backing up the EFS folder BackUp and Restore Before we change anything in our Galaxy S2, we must make a backup of the EFS folder of your phone. Most will say: What is this and what is it? Well, it turns out that the Samsung Galaxy S2 (and other phones) have a / efs, destined to save the data encrypted phone IMEI, as well as WiFi and Bluetooth mac, product code and a number of details . Access to this folder is not user-level novel, but very easy to mess up anything and corrupt that folder either Custom ROMs or flashing with ODIN verily, so it is highly recommended to make a backup as soon as possible. This is so important because if you lose the IMEI, you can not gain it back unless you have a backup of it, and it will generate a generic IMEI all ye that pass. In principle this is not a very big problem, except that there are services that block IMEI’s duplicates and not let you use them, so you better have a good and nice backup to restore your files in case anything happens. And what better time to do it no more rooting the phone? None, since access to this folder needs to be root. Backing up the EFS folder To make a backup recominedo you several methods: 1.

Also, if your intention is to sell it, surely you get more money for it if it is released. There are several methods to release the Samsung Galaxy S2, being worth about for some versions of Android and others to others.

Turn off the phone and put a SIM from another operator, now turn it on. When turn will ask for an unlock code, simply copy the code you previously left and then you can use your phone with any SIM.
