| Risk | Consequence | Mitigation |
|------|-------------|-------------|
| Wrong preloader version | Hard brick (no recovery without external EMMS programmer) | Double-check model CPH1853 only |
| Corrupted file | Boot loop, preloader crash loop | Verify SHA-256 from trusted source |
| Interrupted flash | Dead boot | Use stable USB port + UPS power |
| Auth bypass failure | SP Flash Tool error STATUS_BROM_CMD_SEND_DA_FAIL | Use latest MTK Bypass + LibUSB WinUSB |
