2. ACS uploads firmware file to HTTP(S) server.
3. ACS sends "Download" RPC to CPE (device) with URL, checksum.
4. CPE downloads file, verifies checksum/signature.
5. CPE applies update to inactive partition.
6. CPE reboots into new partition; runs post-upgrade validation.
7. If validation passes, CPE reports success; otherwise, bootloader/ACS triggers rollback.
