Building Android from a certain point in the process?

Which system do you use? Android, Ubuntu, OOWOW or others?

Android 12.

Which version of system do you use? Khadas official images, self built images, or others?

Self built images from Khadas official source.

Please describe your issue below:

How do you start compiling from a specific point in the Android 12 build process?

I see from the link below that you can build from U-Boot, Kernel, or Android, plus all.
But how would you build from the following scenario:

1) Clean build of Khadas official source
2) Wait, I made a mistake.  I wanted to use a different bootanimation.zip file

The only way I know how to do that now is to:

1) cd ~/WORKING_DIRECTORY
2) make clean
3) make modifications again to the bootanimation.zip
4) recompile

this silly mistake would take hours to fix.

QUESTION: Can you mount and modify the ~/WORKING_DIRECTORY/out/target/product/kedge/system.img

Then repackage or start the compile process from this starting point?
Without a make clean?

Please and thank you!

You use
‘make installclean’ instead of ‘make clean’ to save time.
