Modify kindle boot / splash screens and strings

Hello again,

while tinkering with my kindle again I tried ton change the screens which the kindle displays while booting.
I replaced these files so far:
[CODE]
/usr/share/blanket/splash/bg_default.png
/usr/share/blanket/bg_default.png
/opt/amazon/low_level_screens/splash.png
/opt/amazon/low_level_screens/reboot.png
[CODE]
However I noticed that there is another stock kindle image displaying before the progress bar appears.
Any idea where to look for that?

Also:
Where are the strings stored that are displayed on top of these screens?
I did a search for "locale" and "strings" in the file system but could not find them.

Cheers!

Be aware that fudging this up can and *will* soft brick a device.

There are man flavors of PNG.

For kindle cover images they have to have the correct bit depth. Splash screens may not allow color.

Sleep screens and presumably splash screens must have correct dimensions.

Sure. I am using the same formats which I use in my scripts as well.
I was worried that the system might use hashes for file integrity but it is not the case.
