Has anyone been able to find where the animated wallpapers for startup and shutdown are located in the filesystem? i have a 5450 and have been looking and can't seem to find them. Also, does anyone know how to view the .bit files. (ie. poweron, poweroff, wallpaper)

You would have to go to menu then go to display then it would be like number 2 or 3 then click ok then you'll see wallpaper, power up,power off.

The built in wallpapers & startup/shutdown pics are not in the filesystem that you can see with bitpim. Period.

Other pics are there, and can be replaced, such as the standard Get It Now pics & the minibrowser pics.

Right now they are a pain to replace because noone has written a .bar file manipulator yet that I know of, other than the program to build (but not read) .bar files from the SDK.

There are also no ".bit files" on my phone, so you can edit this imaginary format with whatever you want.

woah, there ARE .bit files there... just not in my old backup from before putting all my wallpapers & stuff into the phone.

Unfortunately, examing those 3 files, they are just raw 16-bit per pixel bitmaps with the normal BMP header replaced with the following 4 bytes:

first 2 bytes: horizontal resolution
second 2 bytes: vertical resolution.

I'm about to switch my phone to the built in animation and see what happens to those files...

The bit files are whatever downloaded pic you picked last.

I made a quick & dirty .bit-to-bmp converter which has source attached if you want to try it. This one doesn't read the image size from the header and uses a static bmp header (so it will only really work for 120x98 images as is).

cleaned it up a bit to work for any resolution .bit/.bmp 24-bit color bmps only

WARNING: USE AT YOUR OWN RISK - putting a bad .bit file into your phone will make it continuously reboot - to get out of this cycle you need to:

1. take battery out
2. put battery back but DON'T PRESS POWER BUTTON
3. put the phone on the charger
4. fix the file with bitpim WHILE THE PHONE IS "OFF" (yes, it actually lets you replace files while it's "off")

I did a diff after changing wallpaper to figure out where the phone is storing the current setting for built-in wallpapers. Offset 0x948 of nvm_0005 says which built-in wallpaper you are using if any. Replacing the .bit files has an effect only if you are NOT using any built-in wallpaper. It lets you change your wallpaper without having 2 copies on the phone (one as .bmp or .bci, one as .bit). Not too tremendously useful as .bci is much smaller than .bit anyway.
