I require some help to go ahead with Acer Iconia A210 Tablet upgrade. I am trying to upgrade the same to jellybean. But it is not working. I found a jellybean iso file from web. Officially it is not placed on the Acer's website. As per instructions I just have to load files in the SD card and run that on boot. But it is not working. I cannot find anything on my screen when I choose it. I want some help here to install Jellybean on my tablet. Is there any better way available.
