I want some help to update Jellybean on Acer Iconia Tab A210. It came with ICS and on the official website I can find the download of Jellybean ROM. This is a official rom. But I am not aware about the procedure. Also I want to know whether it is safe or not. What if there is some issue and I want to restore everything back. It is necessary to backup the photos from tablet. What if I loose all my paid games. How to get them back. I don't have any copy with me.
