I was running CM9 alpha on my infuse until I encountered an odd problem. Every time I try to reboot the phone, the Samsung logo will appear and then disappear as if it is about to boot. The only problem is right when I expect to see the boot animation, nothing happens and the screen just goes black. I have used Odin to re-flash stock and I get a pass but when the stock rom boots the same problem occurs. I can still access recovery but thats about it. What should I do?
