        We are not sure what’s happening. You can use Carbon ROM Android 4.2.2 JB which have almost similar feature like this: http://androidjinn.com/android-4-2-2-jelly-bean-carbon-rom-for-galaxy-s3-i9300.html

          ROM MANAGER propose an update (24 feb), is it a good idea to install it ? and should j proceed the same way j deed with this one ? (recovery mode…)

          • arafat21

            If you using ROM Manager then you only need to choose the ROM and the ROM manager should download it and installed using your custom Recovery. Technically you don’t require to do much.
