Instructions (only for very experienced users):


To install the UCLC5 on your Galaxy Note, you gotta download the firmware (a .exe file) from here and then boot your Galaxy Note into download mode. For this, first power off the phone, and then press and hold Volume Down and Power buttons together until you see a screen. Press Volume Up to continue to download mode. Now, run the firmware’s .exe file and wait for Odin window to show up. It could take time for Odin window to appear after you’ve run the .exe file, so have patience. If you don’t get an Odin window, then abandon this process. Don’t do anything else. And once you get Odin window, connect your Note to PC, it should show in Odin as added! Press Start to begin updating the Galaxy Note with ICLC4 Android 4.0 Ice Cream Sandwich firmware.
