Huawei does not publicly list consumer firmware for the DSL3890. However, if you have a business account, you can request the firmware via Huawei’s Technical Support portal. You will need your device’s serial number (SN) and proof of purchase.
Let’s assume the user finds a working link. They download a file named something like DSL-3890_V1.00.21.bin.
They log into the router's web interface (usually 192.168.1.1). They navigate to Maintenance > Firmware. They select the file and click Upload.
This is the climax of the story, and it goes one of two ways:
Scenario A: The Rejection The router looks at the file and rejects it. Why? Because the hardware version doesn't match. The DSL-3890 often has hardware revisions (H/W Ver A1, B1, etc.). If the user has a B1 unit but downloaded A1 firmware, the router refuses to install it to prevent damage.
Scenario B: The Brick The user uploads the wrong region's firmware. Maybe they have a unit meant for Singapore but flash it with EU firmware. The router accepts the file, the progress bar hits 100%, the router reboots... And then, silence. The lights don't blink the same way. The interface is inaccessible. The router is now a "brick."
⚠️ Note: Firmware links are region-specific. Always use the version for your hardware revision (e.g., A1, B1) and region. Example Official Domains (use only these patterns):
Official D-Link Support Portal:
👉 https://support.dlink.com
→ Search for "DSL-3890"
→ Select your Hardware Version (printed on device label)
→ Download the latest .bin or .zip firmware file.

This should always be your first stop. Log into your ISP’s website and search for "Hardware" or "Router Support."

This is the most skipped step—and the #1 cause of failed updates. The DSL3890 has been released in multiple hardware versions. The firmware for a Rev. A router will not work on a Rev. E router.

Real-world example:
Never assume because the model number matches, the firmware will be compatible. Always match the hardware revision.
