: Identifies the current software version, patch level, and exact switch model (e.g., S5720, S6730).
Once the file is safely stored in the switch's flash memory, configure the system to boot using the new software image upon the next restart. Specify the Boot File for the Next Startup startup system-software S5700-V200R021C00SPC500.cc Use code with caution.
If the switch fails to boot or behaves erratically after an upgrade, you can access the BootROM menu during the initial boot sequence via a serial console cable. From the BootROM menu, you can manually change the startup file back to the old, stable firmware version. To help tailor any specific commands, let me know: What is the exact model of your Huawei switch?
This guide provides a masterclass in upgrading Huawei switches running the Versatile Routing Platform (VRP). We will cover pre-upgrade checklists, step-by-step CLI procedures (FTP/TFTP/SFTP), post-verification, disaster recovery, and common pitfalls. Huawei Switch Firmware Upgrade

Wrong architecture. S5720-52P-PWR uses a different VRP compilation than S5720-28X. Fix: Download the specific file from Huawei’s "Software Download" section matched to your S5720-52P-PWR exact PID.
For older models (e.g., S2300, S3300):
The is not merely a technical task but a foundational security and optimization process. By adhering to a structured methodology—preparation, proper file handling, version validation, and rigorous post-upgrade testing—network engineers can significantly reduce risks associated with downtime and data loss.
