Any time you want to upgrade huawei’s device you have 2 methods to do this. The first of them is to use CLI (command line interface), the second is to use bootrom menu. Using CLI is the most popular method. You can configure FTP server on the device and use your PC as FTP client or install FTP server on your PC and treat the device as FTP client. Anyway, you can use TFTP or serial (slow connection) instead of FTP. Sometimes it is not possible to get CLI because there is a problem with software file. It is damaged or does not exist. In this case we can use bootrom menu to download a new software and upgrade the device. Let’s take S5300 as an example.
