| Download with poor network | Pause/retry logic, no corruption |
| USB sideload (.bin or .upd file) | Detects file, verifies signature before proceeding |
| Corrupted update package | Rejects with “Invalid package – download again” |
| Signature mismatch | Blocks installation, logs security event |
