One UI 7... Still don't have it

[adams304]

Can someone please help me out! I still do not have One UI 7 and no option to upgrade to it. I talked to Samsung and they said it's a Mint Mobile problem and Mint told me it's a Samsung problem. This phone was purchased several months ago brand new and fully unlocked. I don't know what to do.

Try factory resetting

The only option is to try using Smartswitch on a PC to see if any updates popup if not you would need to visit a service center to have it tested and possibly updated at the service center.

Samsung intentionally is screwing over people buying a phone made for a major carrier and moving to a smaller carrier, as major carriers pay kickbacks to Samsung for doing this. You need to change your CSC to TMB. Your easiest option is to find an active T-Mobile SIM card (borrow from a friend, or maybe go to a T-Mobile store if they are nice) and stick in your phone and perform a Network reset which will change the CSC code to TMB. Then request an update. Then swap SIM cards back. Keep in mind you would have to do this each time you want an update, and certain features still might not work.

You are incorrect in everything you say. There is no Samsung/carrier conspiracy to work over consumers with unlocked phones. Samsung does not care who your carrier is and Mint and the other discount services pay the major carriers to use their towers. The reason they can discount is because the discounters are not paying for service crews, or equipment.

You are correct that Mint Mobile and other MVNOs (Mobile Virtual Network Operators) use the major carriers' towers, which is why they can offer a lower price.

However, the reason for the update issue is directly related to the carrier. While Samsung may not have a "conspiracy," they do implement a Carrier Specific Configuration (CSC) for their phones. An unlocked phone will automatically apply the CSC of the first SIM card inserted, which then ties the device to that specific carrier's update schedule.

This is why the original user was stuck. Their phone was looking for an update from Mint Mobile's servers, which doesn't exist. The update has long been pushed through T-Mobile's servers, but their phone's software was still locked to the Mint configuration.

The only way to get the update is to force the phone to use the T-Mobile configuration, which requires inserting a T-Mobile SIM card. It's a technical challenge that is a direct result of how carriers and manufacturers handle updates.

I hope this clarifies my original point.

No idea where you get that theory

[Demon-Hunter]

This isn’t a “theory,” it’s literally how Samsung’s firmware distribution works.

Samsung phones rely on a CSC (Carrier Specific Code) to determine where they check for updates. Even factory-unlocked devices assign themselves a CSC based on the first SIM inserted. If that CSC is tied to an MVNO like Mint, the phone won’t ever see updates because MVNOs don’t distribute Samsung firmware — only the major carriers do.

That’s why putting in a T-Mobile SIM flips the CSC to TMB and suddenly updates appear. This isn’t speculation — it’s documented on Samsung’s own forums, on SamMobile’s firmware database, and across XDA threads where people run into this exact issue.

So yes, the OP’s problem is the CSC, and the fix is to use a T-Mobile SIM to get the update.

I'm aware of csc but that applies to unlocked phones not mvno

[Demon-Hunter]

The OP literally said their phone is unlocked — that’s exactly why CSC matters here. Unlocked Samsung phones adopt the CSC of the first SIM you put in. If that SIM is from an MVNO like Mint, the device sets a Mint-based CSC. The problem is Mint doesn’t host or push firmware updates, so the phone ends up waiting forever. That’s why inserting a T-Mobile SIM forces the CSC over to TMB and immediately makes the updates available. This isn’t theory — it’s how Samsung’s firmware update system works, and there are plenty of documented cases of people resolving the issue by changing CSC.
