For that, verify that you have installed the USB drivers for Samsung’s Galaxy S3 properly. You will need to connect your Android phone with the computer.

Like that, you can be sure that nothing bad happens while you try to update your phone, so find the time for this step too. Despite of the fact that the factory reset only wipes clean the system partition and it has nothing to do with the data from internal storage, as a precaution, back up your handset. The RR Marshmallow 6.0.1 ROM is based on AOSP Android 6.0.1, CyanogenMod builds, slimROMs, Omni and on previous original Remix releases and it can give you exactly what you are looking for: I am talking about lockscreen shortcuts, a Dark Material Theme, Quick-Smart pulldown, network traffic monitor, battery mods, ambiant display, quick unlock and not only, so let me be your guide in your way to this adventure.įirst of all, note that your phone has to be rooted and it should be running the most recent version of CWM or TWRP Custom Recovery or else it cannot support such an Android 6.0.1-based custom ROM. On the contrary, you still have a chance: you can flash a custom ROM like the one built by the Resurrection Remix team.

Your handset is quite old, but don’t you imagine that there is no solution left for you. In case of being the owner of a Galaxy S3 LTE I9305, then you know that the official Android 6.0.1 Marshmallow is not for you anymore.
