You don't need the old version, just download and install the new one
0.7 Android zip but it not opening
If your device can't handle zip files by default, you need a separate app, like ZArchiver, to extract the contents.
You have some YouTube channel something that can help i try to place file in but it doesn't work
Here's a step by step guide I made.
