TL;DR

• Samsung appears to have disabled Odin and removed Download Mode with the latest One UI 8.5 firmware.


• The change currently affects the Galaxy S26 series and Galaxy Z Fold 7.


• This update will prevent people from using Odin to downgrade software, install new ROMs, or install leaked firmware.

Update: March 12, 2026 (10:21 PM ET): According to tipster @theonecid, Download Mode and Odin are still available, but it appears Samsung is making you go through additional steps. You now have to enable Maintenance mode first before you can enter Download Mode.

Original article: March 11, 2026 (4:18 PM ET): 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.
