Upgrade HTC Incredible S to Android 4.0.3 Ice Cream Sandwich with Virtuous Quattro ROM

February 7, 2012

Owners of the HTC Incredible S surely love the phone and its 4-inch cinematic display and surround audio powered by SRS. Aside from having a unique contoured design for a tighter grip, the HTC Incredible S also packs a 1 GHz processor for efficient multitasking and a built-in camcorder for capturing moments in HD–both of which makes the phone superbly appealing.  As if those weren’t enough, the HTC Incredible S now has one more reason to become more lovable–Android 4.0.3 Ice Cream Sandwich accessible to the device via the Virtuous Quattro ROM.

Directly built out of pure AOSP code, the ROM is expected to bring a pure Ice Cream Sandwich experience to HTC Incredible S users.  The ROM is reportedly pre-rooted and optimized for the Incredible S.  Though, since the firmware is still in alpha development, you can expect several bugs and issues here and there, although the majority of ICS features work right out of the box.

If you want your HTC Incredible S to taste some pure and sweet Ice Cream Sandwich, installing Virtuous Quattro is your key.  Read on to know how to.
