Hello, i am attempting to fix my wifes phone. When i hold the volume down, home and power button i get to a download page. when i hold volume up, home and power i get to a screen that lets me wipe all data. I have reset to default and cleaned the cache, no change. I have also used odin3 to load new firmware i downloaded from samsungmobile Even after all this the phone still sits on the samsung logo during boot. What else can i try?
