I will give an example of updating the firmware of the Huawei Quidway S2326TP-EI switch.
First, let’s look at the current firmware version:
display version
You can view the list of files in the switch memory using the command:
dir
Let’s see what files are specified boot:
display startup
Unnecessary files can be deleted like this (if you are not sure that the switch will start with your new firmware, then it is better not to delete it):
delete /unreserved s2300-v100r006c01spc100.cc
Official firmware is located at (registration required):
http://support.huawei.com/enterprise/softdownload?lang=en&idAbsPath=fixnode01|7919710|9856733|7923144|16561&pid=16561
The firmware I was flashing can be downloaded here:
https://files.ixnfo.com/Firmware/Huawei/S2300EI-V100R006C05.zip
From the archive with the official firmware, I only flashed the S2300EI-V100R006C05.cc file and the S2300EI-V100R006C05.web.zip file for the web interface, then with my configuration file, changing the IP address to it in advance. The bootrom file can change the password on the bootrom menu!
Also, just in case, I saved the version of v100r005c01spc100 (since I noticed that some switches might not start on new firmware and rebooted cyclically):

The downloaded firmware file will be saved on the TFTP server and uploaded to the switch:
tftp 192.168.1.3 get S2300EI-V100R006C05.cc
How to start the tftp server I described in these articles:
Starting a TFTP server in Windows
Installing and Configuring a TFTP Server in Ubuntu
We indicate that it is bootable:
startup system-software S2300EI-V100R006C05.cc
Reboot the switch:
reboot
Done, the switch should boot from the new firmware.
