rakesh, eemember that Rice is not going to clean your phone or prevent corrosion. It does not do anything. First thing to do, is to remove the battery and no longer try to turn your phone, to charge or to sync it. Disassemble your phone, using these guides to help with that. Once you have it totally disassembled, clean all the parts with a high grade isopropyl alcohol. Remove any EMI shields to ensure a proper cleaning. Check this guide for a proper procedure. Even so it was written for an iPhone, it will still be of help to you. Of course, if you have access to an ultrasonic cleaning, that would be the better way. 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.
