4 months ago, critor released mySpire(http://www.cncalc.org/forum.php?mod=viewthread&tid=9441) which allowed modification of nspire CX/CM’s boot splash screen. Since the image itself is signed, there is no way to change the image except modify its position, size, etc.

However there is still a workaround. It’s possible to use third-party payload to display extra things on the screen. So here it is.

Hardware requirement:

  • Boot2 Version 1.4 on a monochrome one.
  • Boot2 Version 3.1 on a color one.

Download: https://www.cncalc.org/thread-9774-1-1.html

Usage:

  1. Pick a picture you like, resize and crop it to 320×240.
  2. Open Img2Lcd, open the picture.
  3. Set maximum size to 320×240 and click the arrow right near the textbox.
  4. Set output color to 16bit True Color (16-levels of grayscale for monochrome one)
  5. Deselect MSB First
  6. Select Invert only if you are using a monochrome nspire
  7. Set output format to .bin
  8. Save it as bootlogo.tns
  9. Transfer the file to nlaunch folder on you nspire
  10. Install nLaunch provided.

Tips:

  • If you want to change the boot splash, simply update the bootlogo.tns, no re-installation required.
  • If you are using a CX/CM, it is recommended that you also use mySpire to move the progress bar so it fits your splash screen.
