That did it! The trick is not using compression on the zip file.
By the way, the desc.txt file is in the Unix format which has only a new-line character at the end. The Windows(DOS) format as a new-line and carriage return character at the end of each line.
Thanks for your help. Finally got to see the animation that my son created for me. :icon_ banana:
so we push bootanimation.zip on to the device uncompressed? Any ideas on how to do that on a mac?
There are some "unofficial p7zip" packages available on 7-zip's download site. The command to archive uncompressed using 7-zip command-line version in Windows would be something like:
7za a -mx0 <path>\bootanimation.zip <path>\filename.png
In linux, etc. I imagine the '\' would become '/' but otherwise should be pretty much the same. Use 7za -h for help.
Well, or read this, using p7zip command line
