# How to use Opera to Update firmware?

Sometimes when we click on the upgrade option in iSG, we might encounter a message saying "Download resources are unavailable." This typically occurs because a large number of users are attempting to download simultaneously, causing the download server to temporarily become unresponsive. 

We have provided multiple download links in our online help documentation to support manual upgrades. Here are the specific steps to use Opera for the upgrade:

1）Open Opera in iSG， Add-ons - Opera, click "Open" on the right
