The Root access lets you make changes to the operating system, change settings, etc. delete protected files. So to be root, means that you can customize your device as you wish and use applications like autostart that lets you disable applications either of user or system to not load at startup, reducing memory consumption and battery.
You can also change system settings to record video in full HD, making the longest scan wifi to save battery, or perform overclok processor to run faster on your mobile.
ROOT SAMSUNG GALAXY S i9000 WITH CF-ROOT
1 – Before you start you have to check the version of firmware in which your smartphone is. To do this you have to go to the menu Settings> About Device> Firmware version
2 – We will run Odin-v1.85, click on PDA and select the file CF-Root-SGS2_XW_XEN_LP7-v5.4-CWM5.tar
3 – Now you have to enable USB mode debuggin in development options as shown in this tutorial.
4 – Turn off the Samsung Galaxy S i9000 and start in download mode, for that we must press and hold VOLUME DOWN + HOME + POWER and then when we get the warning screen press VOLUME UP. Upon entering you will see a green Android and below it says “Downloading …” as you can see in the video below.
5 – Connect the Galaxy S to the PC via the USB cable,, when connecting in Odin will see the COM port turns yellow. If this does not happen may be because we do not have updated drivers for that I recommend downloading Samsung Kies from the following link.
Ensure that the re-partition box located at the top left of odin is NOT checked
6 – Click on “Start” in Odin and wait for the process to finish. If all goes correctly COM port will turn green and we will get the message “PASS”.
Ready! you´re already root on your Samsung Galaxy S and now you can install any custom ROM without problems.
