[Epic 4G General] turbosocks:
!!This is NOT a boot up animation, it replaces the SAMSUNG logo BEFORE the animation, you will still have a boot up animation as seen in the youtube video!!

Alright, This has probably been covered for other phones or linked in threads when people asked, but I couldn't find a specific thread easily to do this 'mod'

I did it last night using a tutorial for the i9000 and it worked flawlessly.

For this tutorial it looks like you NEED to be on a Gingerbread Rom (or GB bootloaders), but i'd bet there are ways to do it for Froyo and god forbid Eclair...

Some things you will need:

Odin on your PC (I used Odin 1.61)

Working USB cable

Ability to boot into download mode!

GingerBread ROM (there are similar ways to do this for froyo)

Everything you need <<Download this!! Includes everything you need for this Modification, including Odin 1.82! Credit to connexion2005 for this Zip.

Optional:

Custom logo.jpg image (480x800, <100kb) the zip includes a few plus the one I installed on my phone! I can make custom versions of the one I used for my phone and add them to the .zip at request!!

!!!You can ALSO use this method if you upgraded to GB bootloaders and are still on Froyo!!!

Instructions (modified slightly from connexioon2005's)

Download the above .zip and extract everything into a folder of your choice.

ShutDown your phone and boot into Download mode (Hold 1 on the Slide-out KB and power)

Open ODIN (either 1.82 from the zip or your existing ODIN on your PC)

Connect your phone to the computer and make sure it shows up in a COM port in ODIN.

Make sure AutoReboot is selected and F.Reset time is NOT selected.

Under PDA, path to the "i9000_gb_param_LFS.tar" file in the folder you extracted the .zip to and click START. (This should run fairly quick and only push param.lfs in the 'working' box)

Your phone will reboot, keep it connected to the computer, but DO NOT mount the USB.

In the .zip file, there is a bunch of collected 'logos' to choose from; rename the one you want to use to logo.jpg. The 'logo.jpg' will be the one that is pushed to the phone and used during your boot up sequence.

After you have the logo.jpg that you need, you will run the "i9000_gb_boot_screen.bat" and this will push file to put the logo.jpg on your phone to be used as the boot splash. Follow the instructions (hit enter when asked, lol)

i!IMPORTANT!i

Keep your screen active during this process, as SU will come up , asking for permissions!

i!IMPORTANT!i

Reboot your phone and you should have your 'logo.jpg' where the Samsung splash was, followed by your sanim.zip (boot animation) and your phone will load.

Again, if you are going to use a custom image, it needs to be 480x800 and <100kb to work.

Some users of the i9000 reported a 'soft brick' where Odin hangs up, but all you need to do is reboot in Download, restart Odin and do it again, DO NOT WORRY!!

This process can be repeated as many times as you want, but you have to run the entire process again to replace your existing logo.jpg with a new one. you can't just run the .bat again because it will see the logo.jpg and say [FILE ALREADY EXISTS]

here is a video of my new boot up:

Dark Droid Designz Boot splash

I also added a crude (MS Paint) version of the dark droid splash without the text!

^^ These are added to the .zip file and as stated above, i can add different colored 'glow' around the droid and add text of your choice and update the .zip, JUST ASK!!!
