COMEThe downloaded COME item has an unexpected file type
If the saved item is not the APK you expected, check the browser entry and source. Do not rename an unrelated file to make it look installable.
Read the complete name
A file manager may hide parts of a name or show a type label separately. Inspect the details available on your device. An HTML page, image or archive is not automatically the intended APK even when its title mentions COME.
Trace the download
Return to the page that offered the file and check which control you used. A saved webpage or an advertisement download may explain the mismatch. Avoid opening unfamiliar files to discover their purpose.
Use the proper route
If the current destination offers an Android APK, follow that explicit option. Do not unpack, recombine or change extensions based on unverified instructions. Android and browser warnings still apply to any correctly named file.
A useful next step
Continue only when the offered item matches the Android installation task you intended.
