My Transformer TF700T is displaying the following whenever I try to access settings: "Attention! Android system updating now. Do no reboot or turn off the device during update. Please, try again later..." And then there's the green android robot icon. The rest of the screen is white/blank. This appears whenever I try to access Settings. I can still access the Home screen, start apps, etc., but not Settings. I also canNOT do a factory reset, or select anything different during a cold boot. This started months ago - I remember encountering some sort of update screen, and may have mistakenly touched something on it I shouldn't have. So this may be malware. Although it doesn't seem to be doing anything else except sticking on this update thing. What to do?
