[AT&T Samsung Galaxy S II Skyrocket SGH-I727] TheVelvetTear:
Unfortunately, this is correct. Samsung can be difficult sometimes. One of the only EASY ways to use the bootanimation.zip method in /system/media, is if you install a custom ROM. Like ParanoidMod, or CyanogenMod9. The latest version of CyanogenMod9 (CM9) RC2 for the Skyrocket is VERY stable, and I don't have ny problems. CM9 also comes with overclocking features for your processor, and many other performance boosts to make your Skyrocket to make it one of the fastest phones on the planet.

BEFORE YOU INSTALL ANY ROM! YOU NEED TO HAVE THE FOLLOWING:​

AT LEAST a 2GB SD card with AT LEAST 1GB of space free.

A Windows PC. (Preferably)

NO NOOB SKILLS.

IF YOU WANT TO BACKUP YOUR FILES:​

DO NOT USE TITANIUM BACKUP! YOU HAVE BEEN WARNED. USERS HAVE REPORTED SERIOUS PROBLEMS AND DATA LOSS WITH THIS APPLICATION WHEN INSTALLING A CUSTOM ROM.

You need to use something called GO Backup.

It's in the Play Store.

Go get it.

And back your crap up by making sure everything is checked.

Easy enough right?

TODAY WE ARE INSTALLING CM9 RC2, THE MOST STABLE RELEASE SO FAR.​

To download and configure CM9 RC2 Samsung Galaxy S2 Skyrocket SGH-I727​

You need to have ClockWorkMod Recovery (CWM). There are 2 ways to do this:

1.) Play Store (YOU NEED TO BE ROOTED): Search for ROM Manager on your android and install it.

Open the application on your android, and choose: Flash Clockwork Recovery.

OR YOU CAN:​

2.) Odin (See attachments Odin 1.85.zip, and SkyrocketCWMrecovery.tar): Open up Odin 1.85 on your PC. Make sure that the ONLY thing that is checked is: Auto Reboot. I will say that again. MAKE SURE THAT THE ONLY THING THAT IS CHECKED IS AUTO REBOOT. I AM NOT RESPONSIBLE IF YOU ACCIDENTALLY RE-PARTITION YOUR PHONE AND BRICK IT BECAUSE SOMEONE COULDN'T FOLLOW A SIMPLE DIRECTION. Click PDA on the right, and choose SkyrocketCWMrecovery.tar. Wait until it says PASS! in green on the top left box, then disconnect your phone, and let it reboot.

TO DOWNLOAD: THIS IS PRE-ROOTED! :D​

Follow this download link (cm-9.0.0-RC2-skyrocket.zip ): get(dot)cm/?device=skyrocket&type=RC (Replace *dot* with an actual dot: . )

And this one: cmw.22aaf3(dot)com/gapps/gapps-ics-20120317-signed.zip (Replace *dot* with an actual dot: . )

MAKE SURE TO DOWNLOAD THE ATTACHMENT: (SGH-T989_DARKSIDE.CACHE.WIPE.zip) THAT I PROVIDED.

After downloaded, plug your phone into the computer. Then place the files into the root of your SD card, OR organized where you know where it is (like I do). After all the above files are transferred into your SD card, you can now reboot into recovery.

TO BOOT INTO RECOVERY:​

Completely power off your phone. DO NOT have your USB plugged into your computer or charger. It will not work. After the device is powered off, hold the Volume ^ and v buttons on the left of the device, and then hold the power button as well. When you see the samsung logo let go of the power button, and shortly after, let go of the Volume buttons.

I just made a zip to start you off with a boot animation, and some power on/off sounds. These were taken from the Galaxy S2 SGH-i777.

Here are the directories where the files go:

bootanimation.zip -> /system/media/

PowerOn.ogg -> /system/ect/

PowerOff.ogg -> /system/media/audio/ui/​

1.) Transfer from PC to Phone.

2.) Use a file manager. I recommend Root Manager, found in the Play Store.

3.) Put the files in a required directories above in green.

4.) Reboot.
