Cons: It relies on Huawei’s server availability for your specific serial number range. Sometimes, a newer version exists globally but hasn't been pushed to your specific device yet.
Check the label on the device or admin web UI (Model number, HW version, IMEI/SN).
Scans file for malware (if from third party).
