It seems that the owners of the AT&T Samsung Galaxy Note won't have to wait until Q2 to get the Android 4.0 Ice Cream Sandwich update, as announced by Samsung earlier. After Galaxy Nexus and the popular Galaxy S2, it's the South Korean tech giant's big guy Galaxy Note, which is reportedly next in line to get the ICS scoop.

Thanks to the development site Rootzwiki, the ICS i717 ROM for the AT&T Galaxy Note has been leaked, and according to them, they'd spent quite a bit of time doing some testing and quality control to make sure you're going to end up with a satisfactory experience rather than a very attractive paperweight.

Technology Web site The Verge said that they'd also tested out the ROM and confirmed that everything is working as it should. Similar to the Android 4.0 ROM for the Galaxy S2, nothing much has been changed in the ICS ROM for the Note. Still, the notable visual additions could be Face Unlock and the new multitasking menu, said the site.

According to different sources, the Release Candidate version is being tested internally, which suggests that a public, OTA release to the end-user is no more than a couple of weeks away, Redmond Pie reported.

The report also provided a tutorial for manually flashing the Android 4.0 ICS update on the Galaxy Note. But before going ahead, users must be aware of certain aspects:

  • The Premium Suite is not included in this build.
  • The TouchWiz launcher crashes on first boot (but not on subsequent boots), and also, when a Google Play account is added.
  • The build will increase your flash counter.
  • The build will not wipe the external SDCard on install, but the internal SDCard will be formatted while installing the build.

The Verge noted that the only way now for users to get the build on their device is to manually flash an update via their PC. Even if it's quite safe to do so, the custom firmware monitor on the Galaxy Note will flag the manual update, canceling the warranty.

For users, who still fancy manually flashing the update, below are the steps to follow. The guide is only for Windows users.

Users must note that using the method to update devices is their own decision. IBTimes will not be held responsible for any consequence.

Step 1: Download Odin One-Click. [Download link]

Step 2: Reboot Samsung Galaxy Note in Download Mode (Hold Power, Volume Down and then Volume Up).

Step 3: Connect Galaxy Note to a Windows PC via USB.

Step 4: Run the Odin One-Click file. It should detect the device as com3 (in yellow).

Step 5: Click the PDA button and select ICS ROM [Download link]. Click Start.
