How to install Android ICS 4.04 to your Lenovo A1

My niece got a Lenovo Ideapad A1 as a gift last February 2012 but then, the machine was unstable as it keeps on rebooting by itself in random. My niece then after a month of usage did not bother to use it as she prefers to used her laptop than her tablet. She says that the tablet was unstable and it annoys her when the tablet reboots by itself when she is using it. Likewise, the buttons at the bottom of the tablet (ie. Menu, Home and Back) were only lit for a short while before it goes off again. You are left then to try and guess which area are you going to press in order to go to previous page or back to Home screen.

I tried to search the internet for the solution on the above mentioned problem and I came across a possible solution wherein you could upgrade the OS of Lenovo Ideapad A1 from Android version 2.3.4 (Gingerbread) to Android Version 4.04 (Ice Cream Sandwich). I then tried to download the ICS1.2 zip file and begin the upgrading process as detailed on ( with finger's crossed. After the upgrade process, voila, I was able to upgrade the OS to ICS 4.04. hahaha... The problem of rebooting was resolved and the problem of finding the menu, Home and Back buttons was resolved by the newly installed OS. Shown below are the steps that you need to do to upgrade your Lenovo A1. You are adviced to backup all your data before proceeding to upgrade your tablet's OS.
