S24 not updating?!

DiamondDepth — Sun, 15 Jun 2025 00:19:13 GMT

Hi all. I bought an unlocked Samsung Galaxy S24 256gb from Amazon Renewed a few weeks ago. I thought all was going well until I realized I wasn't receiving any updates. I went to check for updates in the settings and got this:

"Your current software version isn't supported. Visit a service center.

Update information • One UI version: 6.1 . Android version: 14 • Current version: S921USQS3AXFC / S921U1OYM4AYB3 / S921USQS3AXFC • Security patch level: July 1, 2024"

Any idea what's going on? How do I get my phone to update? The s24 is supposed to have another 6ish years of updates..

You can try to connect your Phone to a Computer and run Smartswitch on both to see if an Update will be forced to your device. If no update is shown in Smartswitch you would need to contact your Carrier since they are the ones that push the update out or you could try contacting a Certified Repair Center to see if they could load the update for you.

For service information or to set up repairs: https://www.samsung.com/us/support/service/

Or reach out directly to Samsung Support at 1-800-726-7864.

there are no certified repair centers near me, it seems. No update is shown in SmartSwitch.

Do I have to contact my carrier? Would they even help? I bought this phone off amazon renewed, not them.

Are you sure that Amazon sold you a phone built for use in the USA? An international version would be incompatible with the US update. You need to check the phone's model name in Settings > About phone and see if it's a domestic phone.

It doesn't say anything about being domestic/international? My phone's model number is SM-921U

It's possible the phone is locked still

Is there some way I can verify whether or not this is true? It worked with my tmobile sim out of the box.

Theres a imei checker to see if clear or blocked fir some reason if that made sense anyway what my thought was it could be locked still to the original user or perhaps and just a guess not paid off

I just Googled your phone's model number and it is a US phone. You should take this problem to your carrier, they are responsible for updating your phone.

@DiamondDepth Your phone was an AT&T device. It could be carrier unlocked but it is not an unlocked model from Samsung. If it was factory unlocked, the model number would end in "U1".

Interesting. Seems Amazon must've mixed up the listing when I bought it, then. Because it was listed as factory unlocked. It is definitely carrier unlocked, because I am running tmobile on it. How did you identify that it was previously an AT&T device?

How do I fix this? I don't think I can return it now. Do I bring it to tmobile? Can I do it myself?

Seems you may be having a similar issue to me? I'll update you if I'm able to get mine fixed.

danial1234 — Sun, 15 Jun 2025 02:34:28 GMT

Yeah please mines refurbished aswell and apparently '' fully unlocked '' someone said it's probably because I don't have a sim card, I'm hoping that's what the issue is and I have no idea who my carrier is or how to check. This is what my sim status looks like rn

I appreciate this. I'll bring my phone in tomorrow to see if they know what's up. If they're able to fix it I'll update this forum.
