My tablet kept giving me errors whenever i tried to update it. I contacted Acer and was told to do a hard reset. After doing a hard reset i am looking at the following.. Android Version : 3.1 Kernel Version 188.8.131.52 Build Number : Acer_A500_4.010.13_COM_GEN2 As soon as i powered the tablet and went through the connection settings i get a notification of a update. I download all 357 MB of it and tried to install only to receive the same error i had before "invalid update". Now i have tried turning the tablet off, letting it sit, and then hold the volume button up while it is booting. This gives a little message about learning the cache and using the kernal image. The end result is i have a little android on the screen with a yellow exclamation point on it not being real informative of the error. Anyone out there have any suggestions on what to do? Thank you in advance.
