Stop if the device does not match
Vega OS is not compatible. If Developer Options or Install Unknown Apps does not appear after the steps above, do not use an alternate bypass—send the exact model and OS to BoomBox support.
Install only the official file
An unknown-app warning is expected for an APK installed outside the Amazon Appstore. Continue only after code 4556570 opens the BoomBox TV download. If it shows an unrelated page or file, stop and contact support.
