This is the most common "custom" path. It removes carrier branding (Vodafone, Three, etc.) and restores the full Huawei interface.

As of 2025, a few developers have managed to run OpenWRT on the B535-232 via the QSDK fork. This is not plug-and-play.


We will use the "Debranded + Band Unlock" firmware, as it is the safest and most useful for 99% of users.

Some shady Russian and Vietnamese forums claim "Custom Firmware B535." Do not pay for these.

What they actually sell is a modified WebUI overlay (often based on the "Sputnik" or "Ultra" themes). These do not touch the modem firmware. They simply inject JavaScript into the HiLink interface to:

This is skin deep. If you hard reset the router, the "custom" UI vanishes.

Many power users actively seek out the Russian region firmware (often denoted by version numbers ending in specific patterns) or generic WEBUI updates. The goal is usually to:

How is this done? Usually, this involves putting the router into "Download Mode" (sometimes referred to as "Balong USB Boot"). You use a software tool (often Balong USB Downloader on Windows) to flash a specific update file.

Warning: Even this method is risky. The B535-232 has different hardware revisions (v1, v2, etc.). Flashing firmware intended for a different hardware revision will brick the device.
