Oreo update on unlocked ATT S8 with T-Mobile sim - AT&T Samsung Galaxy S8 Questions & Answers

I have an unlocked S8 and I have not got the Oreo update Every time I go to check, it says your software is up to date. Is it because I am using a T-Mobile SIM? If yes, do I need to use ATT sim to get the update?

Yes you need an AT&T sim. Otherwise you will not receive ota updates.

Try it now

When I unlocked my AT&T S8, and stuck in a MetroPCS Sim, MetroPCS updated the phone to Oreo. This also results in the boot logo changing to MetroPCS which I think is unfortunate. And it installed a couple of Metro PCS apps including the voicemail app. This was all interesting since this means a carrier will update an OS on a phone that was originally sold for a different carrier. Seems that could run into problems but maybe not.

Did you figure it out?

I have an AT&T unlocked S8 Active with a t-mobile sim. I tried using an old AT&T sim with no plan, but it did not work. Do I need a sim with a plan to do the stupid update?

Take it to a Samsung Experience in a Large Best Buy and get them to Update it.

Is there any way to manually update it to the latest version? Caz I am stuck on Android 7.0 as well, it won't update.

How long after putting in your metropcs sim did the phone update? I just unlocked an att s8 active today registered on my metropcs account but as of this moment it says it is up to date when it is clearly not.
Thank you

To Update my Sprint Unlocked S7 Running on Cricket, do I need to use a Sprint sim?

I am concerned because I'm looking forward to Android Nougat but I haven't gotten a December security update and the phone uses sprint software. It's using the November update, and I updated right when I got the phone. Except I can't remember if the Sprint sim was in when I updated. For the phone to update, does there need to be a Sprint sim in or can I use my cricket sim? Thanks.

You don't need any specific SIM for OTA's.

Preventing carrier update on Unlocked S7 Edge?

Hi, I have an unlocked US S7 edge that I bought from B&H. I've been using it lately with a T-Mobile SIM. It looks like it has downloaded a T-Mobile security update and is asking to install. I do not want to do this as I suspect it will lock me to a carrier once updated. I've tried resetting the phone and removing the SIM card, but the update downloads every time. Is there a way to disable this or remove the downloaded update? I would like to upgrade to Nougat and I suspect the unlocked phone will get it much faster than the T-Mobile version.

Once your phone is unlocked none of the tmobile or any other updates from any place
can re-lock your phone. It will remain unlocked regardless if you choose to update
firmware, security patches and any other updates.
Unlocked samsung phones are permanently unlocked.
Goodl luck,
Have a great day!

Why didnt my phone get nougat?

I recently bought my s7 edge directly from the samsung website at&t version and got it unlocked to be used on the tmobile network. I tried updating the phone to nougat but at&t software update would say that I am on the latest software which was 6.0.1. I even used a working at&t sim card because I thought maybe you need to be on their network but still it gave me the same thing. Finally I just used odin to update to nougat but I wanted to know if anyone knows why I was not able to update ota?

You are on the international version if you bought it directly from Samsung. They haven't released the international N for the S7 Edge. I know this is frustrating but you aren't the only one. If you can put up with ATTs bloat then go flash the Odin files, they have been released for ATT.

Using the AT&T H910 outside of the US. Does that mean I will never get any update?

I heard that an active AT&T sim card is required for software or system update. Is it possible that I buy an AT&T prepaid sim card from ebay and use it solely for system update outside of the US?
Yes. As long as you are on an AT&T network. Roaming on another provider will not work. You have to have an AT&T SIM *AND* be on the AT&T network.
The other very LONG way, is to root your phone, and then flash the latest firmware. If you don't want to stay rooted, then you can flash the latest full stock firmware which will take you back to stock.

I have this issue as well, unlocked AT&T version on Cricket, I bought a GoPhone SIM hoping that just putting it in the phone would work, but it needs to be active.
Okay thanks for your replies. I guess there is nothing more I can do about it then.

Upgrade old firmware on VZW unlocked phone to ATT

Hi,
I'm a little confused here. I want to upgrade my firmware on an unlocked S8 I bought SM-G950U and it's currently running G950USQS2BQL1 which is VZW FW but I have att as a provider.
To update my firmware do I flash VZW FW or can I flash ATT FW? If I'm able to flash ATT will updates be pushed OTC from now on? Also is there a way to upgrade without wiping the data? Lastly, can I update straight to Oreo (one again without losing data?) The OTA function never provides any updates.
Thanks.

Flash the US XAA firmware and you will get rid of all the carrier bloat and get updates straight from Samsung servers.
If the S8 is unlocked then you can just pop in the Verizon sim and it'll ask to reboot and then you'll have the ATT FW.

Okay, so I need a Verizon SIM to update the device?

What month security patch are you on? If its the November or later it should switch to an ATT S8 after it asks you to reboot. If its earlier then yea you'll be a verizon(doesn't have to be active) sim to get it to take the OTAs to being you speed, and then it'll change to an ATT S8 after asking for a reboot.
Edit: You don't have to flash a different carrier version, it'll change itself on the newer FWs to match whatever sim is in the phone.
