Need modify fullbuild.sh to fix this:

./fullbuild.sh: 38: Syntax error: "fi" unexpected (expecting "then")

from

 36 if [ ! -d $ANDROID/androidupdate/data/modules
 37      mkdir -p $ANDROID/androidupdate/data/modules
 38 fi

to

 36 if [ ! -d $ANDROID/androidupdate/data/modules ]; then
 37      mkdir -p $ANDROID/androidupdate/data/modules
 38 fi

previous snippets is missing ']; then' in 'if' clause, also we need to create system dir in androidupdate:

  39 if [ ! -d $ANDROID/androidupdate/system ]; then
  40      mkdir -p $ANDROID/androidupdate/system
  41 fi

Here is my modified script, tested and build successfully:

Thanks, that was a last minute addition to the script based on your previous input. I had to change a couple of things from my script to keep in line with what I had originally posted as well, so thanks for catching those. I'll update them right now
