Grab your USB cable…again. Samsung has made the AT&T Galaxy S II Android 4.0 Ice Cream Sandwich update available via Samsung Kies. Earlier this week, we excitedly reported that AT&T had released this update, sadly to see it removed without a trace. Samsung and AT&T were apparently just “testing” the release and preparing their servers for distribution. Don’t worry SGS2 owners, this time, the update isn’t going anywhere.
To get started, follow the instructions below:
Download and install Samsung Kies to your computer.
NOTE: Any previously downloaded versions of Samsung Kies will not work correctly for this upgrade. Please ensure you are downloading the most recent Kies software from the link above.
Once installed, read and accept the License agreement, and then click Next.
NOTE: If prompted to update to a newer version, click Update and wait for new files to load.
Once all updates have been processed, the program will close and relaunch itself.
Update your Galaxy S II
Plug your phone into the computer using the included Micro USB cable.
Once Kies recognizes your device, you will receive a pop-up requesting to update to a new firmware version.
Click Update to continue.
Read through the Caution pop-up, and if you agree, click to check “I have read all the above information.” and select your desired information saving option, and then click Start Upgrade.
A notice will display. Read through the information, and then click Next to proceed.
The update will begin and may take 10-15 minutes to complete. The phone will be unusable during this time. Do not disconnect your mobile phone from your PC or power the PC off. If interrupted, your device could become inoperable.
Please wait until your phone reboots completely, and then select OK to finish.
Congratulations, you now have Android 4.0.3 running on your AT&T Galaxy S II.
