You’ve heard of CyanogenMod, and you know you want CM9 based on Ice Cream Sandwich Android 4.0 to get great performance and customization on your AT&T Galaxy Note. Thanks to XDA Forum Member h0tw1r3, an unofficial CM9 ROM for the AT&T Note is now available. Waiting for Samsung/AT&T to release the official update? Don’t wait anymore, as you can try out CM9 instead.
Important! This is an unofficial ROM and also, since no official ICS ROM for the AT&T Note is out yet, this ROM will have some bugs and issues in it and may or may not be stable enough for daily use. Check the latest list of issues in the ROM by visiting the official development page (linked in step 4 of the procedure below).
NOTE, Please Read: Since this is an AOSP based ROM, some features like 3G video calling will be unavailable as those are only possible on stock Samsung ROMs (video calls using 3rd party apps like Skype will work fine though). Also, if you use Swype as your preferred keyboard, you will need to download the beta version from beta.swype.com as Swype is also not included in the ROM.
Now let’s take a look at how the unofficial CM9 ROM can be installed on your AT&T Galaxy Note.
This firmware and the guide below is compatible only and only with AT&T Galaxy Note, SGH-i717. It’s not compatible with any other device, including international version N7000. Check your device’s model number in Settings » About phone.
