Download FAQs

The download link is broken!

Since we use caching and the server has special sync functionality, sometimes some newly posted games will have broken links for a few minutes. You can try again in about 5-15 minutes. If after a long time the download link still fails, this is definitely a mistake in the editor’s link import process.

MOD Not Working

We always do thorough testing before posting games and apps. Please read MOD Info carefully in the content. If it still doesn’t work, report it back to us

Error "App not installed"

This usually happens when you already have the original version or version downloaded on another website on your device. To fix it, please delete the app or game (remember to backup data if necessary), then reinstall our apk file
