I would like to do the unroot and install the version of android 4.1.2 . Through kies, official way.
They told me it was simple and without risk but it is always good to ask. I'm always worried about making a mess, so if you can guide me.
Another question is about the root on android 4.1.2. I can use the siyah kernel v5.01 for root version 4.1.2? The procedure is the same as I did on my s2 4.04? I insist on this procedure because I found it very easy to be done.
And When I speak of procedure , it would be this one?
Step1 : Make sure your SGS 2 is not connected to computer via USB and switch it off .
Step2 : Start Odin 1.85
Step3 : Start the phone in Download Mode ( Hold Volume Down , Center button and Power Button Simultaneously ) .
Step4 : Plug the SGS2 to the USB and computer.
Step5 : Look for the yellow indicator in the ID : With That section Confirms That All Necessary drivers are installed on your computer . (If the yellow indicator does not switch on , you will need to install USB drivers on all your computer and Samsung KIES Also to check the option in setings , Wireless & Networks , USB Setting.
Step6 : Press the PDA button . Select Siyah KERNEL 5.01.TAR . Press START . This will launch the update . at the end Should reboot the phone . Do not worry if this takes longer than usual to reboot , that's how it Should be .
Thanks for the help and I know they are basic questions but I really am afraid of damaging my phone.
