@jlutz555 looks like the last .sbf doesn't work i tried about 15 times on two computers. at the moment i'm unrooted/droidless(serviceing) so it may take awhile depending on how slow verizon wants to be this month

Droid 1 custom bootloader logos to replace Motorola logo
- Thread starter MotoCache1
- Start date
Try redownloading it, i just tried downloading it from my link and it worked fine.
I'll have the other one done some time tonight.

electronics just seem to hate me sometimes
Try these two...Here's an image for one of the geniuses here...

@jlutz555 again thanks man. the new one worked perfect first shot,still dunno what happened with the other one but no biggie this is what the girl wanted so i'm happy
Damn. Was just about to take a crack at this, only to read through the thread to find out it wasn't a full screen image. To bad. Wanted to flash this image attached bellow 
Lol, just noticed that the max size is 620 x 280 for bmp files on here. converted it to a .png.

MotoCache posted a clean & working standard logo only sbf file in the thread about replacing your default boot image:

Hi all. Well, I fell off the planet again for awhile -- very distracted with another mission at the moment. Catching up a little here.
First order of business is to post the completed CG42 maker script that I wrote (and mentioned) awhile back, but just finally got tested and finalized. This is an expansion and improvement of the more basic script I originally posted in the middle of this post.
Rather than attaching as a file I'll just make a CODE block and paste it. It's only like 121 lines. Copy this text to a text editor on your machine (notepad, gedit, etc.) and save as "MakeCG42FromBMP2.pl" (at least that is the name that the syntax screen will reference).
This script will take a normal, unmodified 480 x 182, 24 bit BMP file, remove the first 54 bytes (clip), mirror it left to right (mirror), flip it top to bottom (flip), and pad 64 bytes of 0xFF to the end (pad). These are the things that you normally have to do to the file manually to make it show correctly on the phone.
The script does some basic checking to make sure the input file is the right size based on the switches you use.
I tested and validated it and it works well for me. If you find any bugs, please let me know and I'll correct this post.
To use:
On Windows (at a command prompt, with Perl installed, with the script and the .bmp in the same directory you are presently "in"):

./MakeCG42FromBMP.pl yourfile.bmp
The Code
Code:
#!/usr/local/bin/perl
# MotoCache1 - take 480 x 182, 24 bit BMP file and make it into a CG42 code group
#
# Syntax:
# MakeCG42FromBMP.pl filename.bmp [/noclip] [/nomirror] [/noflip]
#
# Ordinarily the BMP file needs to have the first 54 bytes removed (clip),
# the image needs to be mirrored (mirror), the image needs to be flipped (flip),
# and 64 bytes of 0xFF needs to be padded to the end (pad). If any of these
# steps have already been done to the supplied file, use the appropriate
# switch to tell script not to do it again.

}The image size is the same and this script will function as designed to create a suitable CG42. However currently the only options for a custom boot logo for the Droid X are here:

Have a read here:
http://www.droidforums.net/forum/droid-labs/79211-hacking-erroneous-output-sbf-codec.html
The problem of SBF Codec creating wrong checksums when the sbf contains only a single code group still exists. Until we develop a way to calculate the correct checksum or until I get a Droid X to test on, someone else with an X is going to have to take the reins on creating boot logos for the X. The latter of which is not likely to happen unless someone wants to give me a Droid X.
