It’s a good day for Indian users of Samsung Galaxy S2 GT I9100 as they will be witnessing the official ICS firmware via
KIES. Users on beta or custom firmwares will not receive the official update via KIES since it won’t recognize the device on beta or custom ROM firmwares. Thus users on beta or other custom firmwares need to apply this update manually by following the procedures discussed here.
You do not require your Galaxy S2 smartphone to be rooted prior to applying this update. Users can proceed with this update even after applying this update. If your device is rooted from before then the rooting access will get cancelled after applying this update.
