Jay, I just watched the Youtube vid. It is not difficult. The only thing though, is that it requires GB. AND I am on the Sprint 4.0. So, I need to switch to GB somehow. Suggestions? :-\
It doesn't matter what ROM you're on now, only that you first flash a Gingerbread kernel repacked with Clockwork Mod Recovery. This is a safety precaution as flashing from a Gingerbread based kernel/recovery is known to be safe from the EMMC brick bug that plagues this phone (and a few other Galaxy II based devices like the G-Note).
So here is a quick rundown of how the process would go for you from stock Samsung ICS:
First you need to root your phone. Follow this: http://forums.androidcentral.com/ep...oot-e4gt-latest-method-ff18-ics-firmware.html
The reason you want to root first is to be able to use Mobile Odin (more on that below).
Once on stock FF18 rooted ...
Download CM9 Alpha 6 ROM, the latest GAPPs (Google Apps), the EL26+CWM5 kernel, Calkulin's Format All script ZIP and Mobile Odin and get all the files onto your phone.
Note on Mobile Odin: Mobile Odin Lite can be downloaded for free from XDA if you have a forum account and installed manually: [09.07.2012] Mobile ODIN v3.00 [ROOT] - xda-developers. It can also be downloaded from the Play Store for a fee. It's a very useful tool for our phone and worth the cost, but the free version is sufficient for most needs.
Mobile Odin is generally recommended over desktop Odin for flashing kernels because 1) it's easier and 2) it does not trigger the yellow flash triangle on the boot screen or increase the Odin flash count. Both issues can be resolved fairly easily with Triangle Away or a USB jig, but for the novice flasher, avoiding both in the first place is preferable in my eyes.
So!
Steps:
1) Use Mobile Odin to flash the EL26 kernel.TAR you downloaded
2) After the flash and when the phone reboots and hits the SGSIII screen, pull the battery out or hold down the power button to power the phone off.
3) Boot into recovery by holding down Vol UP + Power at the same time
4) Install Calkulin's Format All ZIP
5) Install the CM9 Alpha 6 ROM
6) Install the GAPPs
7) Reboot
Note on #4: One can perform the same as Calkulin's Format All ZIP by manually wiping cache, dalvik cache, data and system from recovery, but flashing the format all ZIP is easier and involves far less menu selections in recovery.
