Hi all! I have A501 (Snid: 13320746815) and I made user reset from the Android (from OS), it went ok, but after reboot it won't load OS anymore. Only acer logo appears. My friend tried hard reset, but no success. He said OS is broken and reinstall is only option. 1. What package (it must be whole OS installation, not any update) I need? 2. How do I start it? I have MicroSD card. Please help!
