Ok... Now I know where is your mistake
We speak about tweak DD, option 4. Here you have 3 questions about the text:
1. "Use light, normal or bold (def. light): "
2. "Write size (def. 1.8): "
3. "Write color code (ex. FFFFFF): #"

You need answer to all 3 question, because I use simple sed commands and if you don't write nothing in one or more questions, you will get reboot-loop...
I started to work on the update, that script will check all strings, and if people forgot to write/answer on some question, the script automatically will insert default string..
