So last night I replaced a LCD/digitizer assembly. It was very difficult to do. I had to pry off the old one which completely destroyed the screen. Anyway now that I have it back together the battery icon shows a red exclamation. And I can't download any apps. I get package invalid. Also, I cannot get into the boot loader. It shows the android guy on his back and "no command" underneath it. Also, I can't update to kitkat it says download failed every time. Any ideas?
