Dear Techies
I have tried upgrading my galaxy win/grand quattro to kitkat using odin 3.07, after searching in google. It failed . Then I flashed it back to Stock rom and then upgraded using kies. But now the mobile network has become very low to an extend that I started getting miss call alerts. I have no signal when I am in any room. But on the street it shows few signals and even I can make and recieve calls. No problems with wifi or any other apps or process. The IMEI is intact as original as I verified it with my original packing box. Pls help. Thanks in advance. In between I have done a cache wipe too. Nothing seems to be working. Just wanted to know whether my warranty is void due to my upgradation
