Kamran, the very first thing you want to do, is to remove the battery and no longer try to turn your phone, to charge or to sync it. Disassemble your phone, use the teardown for help with that./ Once you have it totally disassembled, clean all the parts with a high grade isopropyl alcohol. Check this guide for a proper procedure. Even so it was written for an iPhone, it should still be of some help to you. While you clean your phone properly, check for any missing, burned or otherwise damaged component. Check all your flex cables, clean the connectors as well. Once that is done, replace the battery and reassemble your phone. Then re-evaluate for any further damage. Remember that Rice is not going to clean your phone or prevent corrosion. Hope this helps, good luck.
