[Q] Can't Update My Samsung Focus

Hey,
So I bought a new Samsung Focus device on Ebay(my carrier is not AT&T) and I can't do any update to the phone.
When I click the Settings>About>More all i can see is that the OS version is 7.0.7004.0 and I the cell phone says that it's up to date.
Also when i connect it to Zune, it says that the phone is already up to date.
If anyone could give me a full guide of how to update my phone..
P.S: My phone is Unlocked.
Any help will be appreciated too .
Thank you!

All AT&T branded WP7 devices are on 7004 now.
Wait for AT&T, or debrand ur phone.

What do you mean by "debrand" the phone? And I saw some samsung focus devices with NoDo and the first patch on Youtube.
Can you please also explain how will AT&T send the update? will it be through Zune? (My carrier is not AT&T)

Updates come from Microsoft to your Zune software. Since your phone is AT&T branded, AT&T is currently blocking all its WP7 phones from receiving updates until it finishes its testing. Debranding requires you to jail break your phone and remove the carrier branding entries in the registry so that your updates are no longer held back by AT&T.
Updates are not coming from AT&T but AT&T can block your phone for receiving updates.
You're looking at end of April time frame for AT&T phones to start receiving current NoDo update.

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!

Won't search for latest OTA updates

Hi, I bought a Galaxy S7 edge sm-g935a, and I'm using it here in Japan with other network. I'm just wondering why everytime I check for an update, it always says I'm on the latest firmware even when I'm like 3 or 4 versions behind. Even when I connect it to smart switch it also says I'm on the latest firmware too, and when I try to click on firmware upgrade and device initialization, it says "Galaxy S7 Edge does not support initializing, please contact customer support". What should I do to get OTA updates? Thanks

AT&T phones will not receive OTA updates if you're not on the AT&T network. You have to manually flash them. You could keep downloading the latest firmware and flash it, or you could download the U firmware, which will receive updates regardless of carrier.

I'd consider switching to the 935U Firmware, it kills the useless AT&T bloat, and you'll get OTA's

Thanks man, I tried searching for its latest firmware but none of it seems to work out, I found some on google and download it but when I tried to unzip the files, all the files that I've downloaded we're corrupted LOL. I'm now switching to 935U firmware :good:

My S7 edge won't update either. I seem to be stuck on the May 2017 security update (Build # G935AUCS4BQE1). I bought my phone from swappa.com last month. The seller had it listed in the AT&T section as the SM-935A. I can use it for the most part without any issues (no Wi-Fi calling, not recognized on the AT&T network). When I check the IMEI # with Samsung, they show it listed for Sprint. Any suggestions of what I should do? I know one option is to flash the 935U firmware.
Thanks in advance.

All US (Snapdragon) based S7 Edges are physically identical, so you can run AT&T firmware on a Sprint S7E and vice-versa. However, AT&T is well known for disabling features based on IMEI, which it appears they are doing for WiFi calling. Unfortunately, it appears someone converted a device that started life on Sprint, so unfortunately you may be out of luck. The only way to fix the problem that I am aware of is to temporarily switch your SIM out for an actual AT&T device (whose IMEI is recognized), and that supports WiFi calling and VoLTE, then put the SIM back in your converted S7 Edge.
Converting to U will definitely make the phone a LOT faster (and the battery last longer), but you are giving up on any carrier features period at that point. I personally felt that the performance and battery features were a lot more important to me than WiFi calling or VoLTE and I switched to U a while ago. I haven't looked back, but that's just me.

Thanks jshamlet. I did a chat with Samsung and they confirmed that my phone was originally setup for Sprint and that it has been unlocked. My fiancee has an AT&T branded S7 Edge, so I can try putting my SIM in her phone for a bit. Converting to the U is something I'll seriously consider. I had an unlocked Moto X Pure Edition, so I'm used to not having the Wi-Fi calling or VoLTE.

I ended up using Odin to flash the SM-G935U firmware to my phone. Once that was finished, it downloaded and installed the April - August security updates, so I'm happy now. Also, no AT&T bloatware.

Here are the Firmware updates for the ATT 935A.

Why AT&T makes it so hard to update their phones?

Hi,
I really love my G892A S8 Active that I've purchased used in Canada.
But for some reason AT&T don't want their phone to be updated while on another network. This is the first carrier I've seen that does that (blocking OTA updates). Any real reason for this?
I've even tried with a prepaid SIM card from AT&T and paid the 35$ plan to later found out that you really need to be on the AT&T network (US) instead of a roaming network with a working ATT plan.
Even the attcompute.com site where I used to get OTA updates looks it is now blocked from any Canadian ISP.
xdmd.sl.attcompute.com/agents/48974/1488/SS-G892AUCS2ARA1-to-U2BRA3-UP
This used to work 3 weeks ago with the phone user agent. Now, all attempts return DNS look-up failed..
I had other carriers unlocked phone OTA successfully on another carrier network.
This is crazy... why block people from updating their AT&T unlocked phones????
And yes I know about XDA OTA source but it is not always up to date and depends on user base to upload OTA and make it available to general public.
Last security update is G892AUCS5CSH1 but I cannot find it anywhere... not even on xda.
Thanks!
Laurent

I have the exact same problem. I was able to find the pie update but not the last G892AUCS5CSH1 security patch.

they don't do it, because it will broke the sin unlock

The latest baseband for the AT&T version of the Galaxy S8 Active (a.k.a. the G892A) is G892AUCS5CTL1. You can find it linked from this post or this one and install with Odin 3.14.1.

Bought "Unlocked" phone, has sprint branding, seller insists that's how Samsung works

Bought "Unlocked" phone, has sprint branding, seller insists that's how Samsung works
Hi everyone, I bought a Galaxy S10+SM-G975U (same model that all 4 major US networks use) that was sold as "Unlocked" without specifying that it is Sim unlocked, Network unlocked, or Factory unlocked. Most of the time unless a seller specifies which unlocked then it means the phone is Factory unlocked, I gathered this from 9 years of buying and selling Android devices so it's not just a guess.
When I got the phone Sprint OMADM pops up and tells me I have an incomplete activation, "about phone" told me it was Sprint Network Unlocked; after a week it now says unknown under "Brand" in the "status" section.
The seller said that when you buy a factory unlocked Samsung phone and put in a network sim card that Samsung then loads the branding (bloat in my opinion).
1. Is this true that Samsung could have loaded Sprint OMADM?
2. If true can I remove it so that I don't have to "Force Stop" it after each startup?
3. Is there any piece of software or database that I can look up the origin of this phone so that I can either change my eBay review of the sale and apologize for my mistake, or affirm that indeed the seller failed to disclose branding that he knew wouldn't go away when a buyer puts in an ATT simcard such as I have.
I've read one single thread by a user and not a Samsung official that claims that you can pop in a network sim card and then restart to change some software but I have not found even one more thread mentioning this phenomenon.
My background:
I've bought factory unlocked my Moto Pure X and a OnePlus 5 and neither did any ridiculous **** when I switched networks, so that's why I doubt this claim.

I bought a AT&T branded one for use on TMobile. It kept popping up errors. I flashed the unlocked firmware and it works great. I get unlocked updates and everything. You'll need to look on here but there's a walkthrough somewhere. But there are a few advantages for running the carrier branded version so you could flash the AT&T firmware instead. I wanted less bloat so I went with the unlocked one.
Think this might be the thread:
https://forum.xda-developers.com/s10-plus/how-to/sm-g975u-firmware-downloads-tmo-spr-att-t3908657
That said after I did all this I did read there was going to be a update to the firmware which would do what you described.... Switching firmware based on the sim card. Never seen it happen on mine still on unlocked unbranded firmware. Maybe this phone is running old firmware prior to the update that implemented this?

not normal. LIke you, I purchased an 'unlocked' phone and when I powered on, it was a Verizon phone. I popped in my TMo sim, and it worked OK, but I would get the annoying Verizon popups reminding me that I'm on on their network. I installed the unlocked firmware and it went away.
But there's more: when the phone had a problem, I sent it back to Samsung under warranty (still unlocked) and when it was returned, I just installed the original sim and powered on. Now it seems to be a TMo phone, and when I look at the phone's software version, it shows TMB/TMB/VZW. It's been receiving OTA updates and I've disabled bloatware, so I'm OK with it.

Just to be clear I'm not going to flash anything. I'll just turn around and sell it. I need a stable phone for work and I used to mess around with flashing different roms and while it was fun it was a frequent activity and I don't have time for all the annoying trouble this phone has been. Thanks everyone.

Flashing rom is different from flashing a stock firmware. In your case the only way to be completely off from the previous network you are getting the notification from is to flash a G975U1 or G975U stock firmware which is unbranded or your network branded respectively and you are good to go. I switched my yesterday and am okay ?. I will be happy to assist should you change your mind
