1, find your favorite theme, click Use Now, and when you download to 100%, immediately switch the theme store to the background and close it. This must be fast, not loaded;
2. Open the folder where the theme is located, Coloros, Themestore, Themes, and find the theme just downloaded. If not, it's just a slow hand and a theme;
3. Copy the downloaded theme to another folder first, then click the theme in the original folder to try it out immediately, return to the folder and copy the theme just copied.
4. Open the theme, sign it and find the theme signature just now. Go to the theme store to delete the theme you just tried, click on the theme you just signed in the folder and you can use it.
