COMECOME download button returns to another page repeatedly
If a download route loops between pages, stop repeating the clicks and inspect the addresses and download state. A loop does not confirm a saved APK.
Record the route
Note the starting entry and the page you return to. Check whether the same hostname and path repeat or whether the route changes. Do not edit URL paths to guess a direct file or use an unrelated mirror to escape the loop.
Check Downloads separately
The browser may or may not have started a transfer. If a completed intended file exists, use that checkpoint. If no item exists, describe the problem as a page-route issue rather than an installation failure.
Avoid broad changes
Do not disable protection or install a helper because a page tells you it will fix the loop. Record the browser, time and visible message for the current service's help route. Keep account credentials out of the report.
A useful next step
Return to the known entry only when there is a clear next step to test.
