[HOWTO] Update HTC Incredible S to ICS(Ice Cream Sandwich) without S-OFF and Root

I have a HTC Incredible S and I would loved to installed the latest version of the Android OS ICS(Ice Cream Sandwich). As you guys can see lots and lots of post around the internet, I would love to show the same process in a bit quite different way that would be easier. Actually I have updated my Android, the default from 2.3.3 to 2.3.5 from the official HTC update center on the setting menu. And the main problem occurred was that the HBOOT version too upgraded from 1.13.0000 to 2.00.0000(I forgot the real figures). And as you might have been passing through different forums and blogs and asked for using tool names “revolutionary” but the main problem faces is that the device doesn’t support the HBOOT version 2.00.0000. So I looked over the downgrade process and saw a process via RUU downgrade(gonna be 300MB). Well that also didn’t worked for me as well. So I started thinking over and looked for an ultimate solution. And its a good news for you that I got one. Without any downgrade, you can easily install ICS on your Incredible S. The process just doesn’t apply for Incredible S, it may be also applied to following devices: Desire Z/G2, Desire HD, Desire S, Sensation.
