Verifying the Digital Signatures of Software Packages
To avoid using software packages that have been tampered with during transmission or storage, download their digital signature files for integrity check while downloading the software packages.
After a software package is downloaded from the Support website, verify its PGP digital signature. See OpenPGP Signature Verification Guide. If the software package fails the verification, do not use it, and contact Huawei technical support.
Before a software package is used in installation or update, its digital signature also needs to be verified according to the OpenPGP Signature Verification Guide to ensure that the software package is not tampered with.

Upgrade Procedure

Rollback
Rollback Guidelines
If the upgrade fails and the software version is still the source version, you do not need to perform a rollback. If any of the following problems occurs, contact technical support to determine whether a rollback is required.
- A major fault occurred during the upgrade, and cannot be located and rectified within the specified time.
- After the upgrade is complete, the target version functions abnormally.
- The entire upgrade cannot be finished as scheduled. To prevent service interruption in peak hours caused by the upgrade, a rollback is required.
Rollback Procedure
- Determine the target version.
- Roll back the firmware version.
The rollback procedure is the same as the upgrade procedure. For details, see "Upgrading Firmware" in the Smart Provisioning (V124 or Later) User Guide (aarch64).
Note: The required Smart Provisioning version varies depending on the firmware package version. For details, see the firmware package description at the download website.
