Hi - I'm a noob so forgive me if this isn't the best place to post - I have an Acer Iconia A500 and just got an update last night. It was 4.something, I didn't look too closely. The update ran fine but froze part way through and did nothing for a long time. When I turned it off and on, now it goes to the home screen but is completely unresponsive. It shows the right time, but the battery meter never moves no matter how long it's plugged in. Is there a way to fix this, or can I reinstall the update from my computer?
