Rafael figured out a way in this link

As Oregon2 stated, here is a recap info I posted over in that thread:
This requires that you Root the phone to be able to edit/replace the file.
Rooting and unrooting this phone is pretty easy. You can find info on it in the "All things Root" section of this forum.

I renamed the .mp3 sound file and the phone still booted....but it took forever.
I assume it spent much of the time looking for the file.

FYI, this file is located in /system/media/audio/boot/ and is called "wakeup.mp3".

I replaced the wakeup.mp3 file with a 1 second file of silence and the boot audio is now gone. Boots just fine.

I realize this is a crude method of removing it, but it was also damn easy.
Boot time is unchanged.

Here is the replacement "silent" audio file I made and used:

Right click the link from your browser and "Save Target as" on your PC. Then you can move it to SD and use a file manager to replace the existing file. I renamed the old file as "wakeup.3pm".

I use a File Manager from the Market called "Root Explorer".

As to the video animation, I am reluctant to rename it as it looks like an executable file. That could brick the phone.

Anyone know what type of file this is?
It is located in /system/bin/ and is called "bootanimation".

 

thanks for the blank .mp3 lol i was just about to make one when i found this....

i don't suppose anyone's made progress on deciphering exactly what type of file this "bootanimation" is? i just saw it was an executable...

if you extract the file, you get 5 seperate files, numbered 0-4

file 1 for example just says:

/system/bin/linker

file 3 has lots of references to non-existant files such as:

images/nec_gz_animation_loading_1.png

i'm going to keep messing around with this, but i have an odd issue with droid explorer that is really slowing me down....

the device only shows up if i un-root using superoneclick, although the sdcard shows up fine with i plug it in... i used the same drivers with bootstrap everyone else is using...

i wish there was a way to jump right to the program, instread of that "select a device" screen.....

 

Did you read this?

I don't really understand it.

If you make a blank one, post it so we can all use it.

 

Here is a tutorial:

just for the hell of it i'll try it one last time but, this method doesn't seem to work with the casio g'zone commando

 

Cool. but please, do not screw up your phone on my suggestion!

 

yeah didn't work.... i've tried several other paths, with no luck so far...
