https://us.community.samsung.com/t5/Galaxy-S24/S24-update/m-p/3297037#M100397 I just want to clarify that there is a difference between a carrier unlocked phone and an unlocked phone purchased directly from samsung. If your model name ends in U1 then it's truly unlocked from samsung. If it's simply ends in U, then that means it was a carrier locked phone it was unlocked via a code, however it still has the carriers footprint. Have you switched carriers recently? If so, your phone is trying to get the update from your previous carrier which it cannot authenticate. Fri, 11 Jul 2025 23:21:19 GMT Oxford 2025-07-11T23:21:19Z
