changing the script you see when loading your theme (updater script)
if im gonna want a script visible when people load my theme i try to port it into an acceptable for the rom theme with updater script already in it. ive tried to move an updater script over and it caused problems on load up.
go in to the theme you want to change the script on with 7zip and go to
META-INF\com\google\android\ (keep opening those folders until you see updater script)....then drag drop it on to hxd (download link in above tutorials for hxd).
find all the script put in there previously (usually between quotations) and highlight it, then start typing what you want (leave quotations and other fancy marks you want to stay)....when you are dont use the space bar to get rid of any leftover writing you dont want.
then save and drag drop it back in to the same place you found it.
you're done; you should see your words on boot/installation of the theme.
