Samsung’s latest update is a serious gut punch to Galaxy power users

Many Galaxy owners are currently in disarray at the moment. The reason is related to a recent move from Samsung. It appears the firm has made a change to Galaxy devices that will have significant consequences for power users.

According to tipster Ice Universe, Samsung has disabled Odin, a proprietary firmware flashing tool typically used to install stock firmware, install custom ROMs, and restore devices. It also appears that Samsung has removed “Download Mode,” which acts as a gateway for Odin. This change appears to have been made in the latest One UI 8.5 firmware and currently affects the Galaxy Z Fold 7 and recently launched Galaxy S26 series.

When attempting to activate Download Mode, users are no longer greeted by the usual interface. Instead, these users see a blank blue screen with brief instructions on how to exit.

Samsung has yet to issue an official statement to explain why it suddenly made this decision. However, shutting down Odin does allow Samsung to hold a tighter grip over its ecosystem, preventing users from sideloading firmware. It also blocks the primary method many tipsters use to show off leaked firmware. So there are reasons as to why Samsung would want to do something like this.

For average users, this change will likely have no impact on your experience. But for power users, this means you can no longer use Odin to do things like downgrade your software version or install new ROMs. It’s also bad news for service centers that rely on Odin for device recoveries.
