Samsung Galaxy Note SGH-I717 (AT&T): How to upgrade to Android 4.0.3 ICS firmware build UCLD3

May 19, 2012

With reports of the official Ice Cream Sandwich (ICS) update rolling out for the Galaxy Note in Germany,  it seems that even the AT&T Galaxy Note is starting to get its own leaks. Thanks to XDA Developers member Korey_Nicholson and Brief Mobile, users of the AT&T Galaxy Note SGH-I717 can enjoy Android 4.0.3 ICS firmware build UCLD3.

The last leaked firmware for the AT&T Galaxy Note, known as UCLC5, was riddled with performance bugs and other non-functional features. But, luckily for Galaxy Note owners, Samsung was keen enough to fix those pesky little bugs, mostly eliminating them in the new UCLD3 update. However, Instagram was reported not to work on the Galaxy Note, but overall, UCLD3 was praised by most testers for being smooth and faster than ever before.
