see https://forum.xda-developers.com/t/nst-manual-rooting-adb-gapps-1-1-etc.1380400/#post-20069276

here the guide, in case the link goes dead:

Change the powered off screen image
First, let’s make a copy of the original apk.
Open CMD and type:
Code:
cd C:/android-sdk-windows/platform-tools
adb connect yourNSTip
adb pull /system/framework/framework-res.apk
You will find this file on C:/android-sdk-windows/platform-tools.
Make a copy of the file and open it with 7zip (download it if you don’t have it http://www.7-zip.org/).
Look for and open res\drawable-mdpi\
Search for cold_boot_screen.png and replace it for whatever 800x600 image you want.
Search for cold_battery_low_boot_screen.png and again replace it for whatever 800x600 image you want.
Save the modified apk on C:/android-sdk-windows/platform-tools
Then we have to push the new file and fix permissions.
Code:
adb shell
mount -o remount,rw -t ext2 /dev/block/mmcblk0p5 /system
exit
adb push framework-res.apk /system/framework/
adb shell
chown root.root /system/framework/*
chmod 644 /system/framework/*
rm -R /data/dalvik-cache/*
reboot
If you have problems pushing the framework-res.apk because the NST reboots, or hangs, use this zip (http://nooter.googlecode.com/files/RestoreFramework.zip) in conjunction with CWM (http://forum.xda-developers.com/attachment.php?attachmentid=806435&d=1323121399). (Keep reading)
You must:
Open the zip and drop your original or modifyed framework-res.apk in /system/framework, inside the zip.
Copy it to the SD card where you have burnt CWM and flash it through it.
If you see any strange behavior restore your backed up copy.
On this post, there are some nice pictures to use, http://forum.xda-developers.com/showpost.php?p=17822468&postcount=9, I modified them a bit, making them 16 bit grayscale and 800x600, see attachments..

this is the .rar cited in the guide above images.zip

the /system/framework/framework-res.apk apk contains assests for standard UI for the nook, so I'm currently not interested to change them.

What I was trying to o was to remove the ugly /system/media/screensaver/author/Bronte_Sisters.png

and I did it replacing it with an all black Bronte_Sisters.png file made with paint. that image was creating an ugly ghosting at each reboot.

I'll close this one!
