Getting rid of AT&T limitations on S850A - Samsung Galaxy Alpha

Hi everybody,
I am installing Lollipop over the older Kit Kat that I have on my AT&T Alpha S850A. However, I am using a T-Mobile SIM card. And because of that, my hotspot and MMS cannot work, I also cannot do an OTA update, so will have to do it manually.
There is, I believe a T-Mobile version of the Alpha called the S850T, could I download its firmware? If yes, where could I find it. It would probably bypass all the AT&T limitations if I can get that.

[Q] AT&T to T-Mobile S3

Hey guys. I couldn't get AT&T to unlock my s3 so I downgraded to android 4.1.1 to do the free unlocking method. It worked, but my phone has AT&T apps in it, and when updating it says crap like updating from AT&T server or w/e.
When using ODIN, was I supposed to install the AT&T or the T-Mobile version of the 4.1.1 android?
I figured since it's an at&t phone I have to reinstall the at&t so it doesnt mess up the drivers or anything (I totally made up that conclusion myself).
Also, I don't get 4g LTE now and only get E internet. Do I have to do some settings so the phone cooperates with T-Mobile?
As always, thank you very much for the helping hands.

You're probably going to need to setup the apns for Tmobiles network to work for your phone fully.
It automatically made one called tmobile but I dont know if I have to edit it.
Was I supposed to install android 4.1.1 for at&t or tmobile?

As far as i know you should be fine on the at&t rom, You're just going to need to edit those apns probably.

Well, how about this? I install the T-Mobile rom. Shouldn't that have the proper apns?
Now another question comes to mind. Since this is originally an at&t phone, will installing the T-Mobile rom mess it up?
Anyone? Help plz

Unlocked LG G Pad X 8.0 V520 (AT&T) Nougat Update

Update: I'm returning it and went to T-Mobile and got a V521.
Recently with T-Mobile's free line promo I got myself a free line. I picked up an unlocked V520/G Pad X 8.0 (AT&T model). Popped the Tmo sim in and it works great. However, it won't show an OTA update for Nougat, LG Bridge just gives "cannot get software version" errors, and as far as I can tell there is no where to find a KDZ file for the AT&T variant. Confirmed AT&T blocks updates on unlocked devices without AT&T SIM cards.
When I had Nexus devices, I didn't have too many problems flashing variants of stock ROMs while using on T-Mo, anyone successfully flashed the V521 update on the V520 variant? Not really worried about unlocking the bootloader or getting root, just want to be on the latest software -- mine is on a security update from June 2016.
edit: Any ideas on where to get stock AT&T firmware?

What's the magic to get this to update? I have a V520 new out of the box off eBay and I haven't tampered with it (haven't unlocked bootloader, rooted it, etc)... but it's on android 6.0.1 - how does one get this to update to android 7.0?
I'll take a link to that kdz file too, if you'd be so kind! Not sure if I can force the tablet to install that manually, but it's worth a try.
I just received this tablet (Unlocked) and having the same issue. It does not have Nougat OTA update, neither Update can be detected by LG Air Bridge Software. I'll really appreciate if someone can link me to the Nougat file.
Check updates using an AT&T SIM. A user in Slickdeals has reported success - sorry can't post the link - new user here.
Update: I myself tried using AT&T Go phone and it worked.

I also had success yesterday. But even after inserting the sim, it wasn't showing. So I called AT&T tech support, provided the IEMI number and they pushed it instantly.
I also got the LG V520 off ebay. I read in an ATT support forum that it was necessary to have an ATT sim card in the tablet or it will not be able to connect to the update server. The same forum suggested to bring the tablet to an ATT store or the Samsung Experience in a Bestbuy.
I can verify that it is not enough to simply to connect to the ATT wifi in the store, you do actually need to insert an ATT sim. It took some convincing to get the person at the ATT store to pull a sim card from a demo phone to let me try. Here are some tips:
-- The tablet will only allow you to check for an update once every 24 hours. Make sure that you don't check for an update 24hours before going to the store, or once you're there, do a factory reset in order to do the update check.
-- Go to the store when they aren't too busy so they are more willing to help out.
-- Once the tablet detects that there is an update available, you can shut down the tablet and replace with your own sim card. You can then connect to any WIFI connection to finish the update.
Changes in the Nougat ROM:
-- When you create a second profile, it can now enable "install from unknown sources", but there is still no access to the external SD card. It means that the secondary profile can only use the internal memory.
-- ATT pulled the "WIFI Hotspot" feature out of the Nougat ROM.
-- Just like the Marshmallow ROM, phone features do not work. I don't know if this is a firmware lockdown or if it's a software thing.
The lack of hotspot really makes me wish for a custom rom on this tablet. Here's hope we get one soon on the V520

Could any kind person with the file LGV520AT-00-V20f-ATT-US-DEC-21-2016-ARB00+0.kdz please upload it.
I've spent about ten hours looking for this file in the vain attempt to update the V520 to Nougat, before I wrap it and give to my daughter for Christmas.
Many thanks to anyone that can help me out with this.

I would just purchase an h2o SIM card. Since h2o is an att reseller, you will get an update within 24 hours.

Unlocked and now stuck on old software

Hello all.
SM-G965U, was AT&T but now unlocked for Fi. In the US.
Build: R16NW.G965USQS3BRJ6
Security Patch: Nov 1
What do I need to do to get back to the OTA schedule? I'm presuming its to flash onto an unlocked ROM but I can't work out exactly which thread I need to be following to make that happen.
That is the newest update until they release Pie. You can manually flash a beta version of Pie or sign up for the beta program.

Hi Electroz,
I'm still showing 'no update available' even with unlocked US apparently getting the update. Is there anything else I have to do? :/

Wait a few days, the rollout might not be instantaneous
It's unlocked but still run the same AT&T branded firmware. All AT&T phone requires an ATT sim card and in US to receive OTA. It looks like you are on Fi so you need to get an active ATT sim from a friend to receive update.
What is the alternative to flashing some sort of generic ROM instead? Specifically what ROM would I need?
you need firmware version SM-G965USQU3CSAB THATS THE PIE UPDATE . it rebrands based on sim card so you wil be branded tmobile on project fi . here the thread with the link u want https://downloadmirror.co/2CXl/G965USQU3CSAB_G965UOYN3CSAB_CCT.zip

Thanks. I think I'm actually going to go with SM-G965U1 G965U1UEU3CSA8 because I don't believe you get any carrier features with Fi, even if it piggybacks on Tmobile anyway.

Question AT&T Base Firmware needed for A526U

Hello, looking for some help to see if anyone can help me find the firmware of my A526U specifically for AT&T? I have moved my phone over from TMobile where I purchased it from, and am looking to re-flash it to AT&T. Was working fine for a few months, now I'm no longer able to make or receive calls.
After inserting the new AT&T SIM card, the TMobile splash screen still shows up. The Service Provider software version reflects TMobile still as well and I'm concerned that for whatever reason the phone did not fully update after inserting the new SIM. I spent 2 hours on the phone with AT&T support after the store said they couldn't help me. Pulled the SIM card out, restarted phone, put it back in, reset network settings etc. I've searched sammobile and I cannot find the AT&T firmware, only TMobile, Sprint, and TMK. I would sincerely be greateful please if anyone could help me by pointing me in the right direction for the firmware for this model phone.
AT&T doesn't make their firmware available publicly - for any device. I have a source who can get me Samsung firmware for any USA device - even AT&T. But he charges me for each one
I appreciate the quick response! Is there any option I have here? Could I try flashing a "U1" firmware to his phone then? He's currently on A526USQS4CVA6. I actually found your other post as I was also working on my note 10 plus - https://forum.xda-developers.com/t/n975u-and-n975u1-firmware-links-here.3957648/. If I'm reading that correctly, I should be able to correct? If so, how can I tell if the version I'm downloading is "downgrading the bootloader"

1. Yes, you can try flashing U1 if you want
2. You can't "downgrade the bootloader" - Odin won't let you.
3. In A526USQS4CVA6, "4" is the position of the bootloader level/revision/binary. Make sure that whatever U1 firmware you download also has a 4 in that spot and you'll be fine. (Or just get the firmware from Frija or one of the other similar firmware download tools, because those throw you whatever the newest version is automatically)

Thank you very much sir! I shall give this a go this weekend! You guys rock!
My AT&T N10+ N975U is running on Pie. It transitioned seamlessly with no changes made on my end. It was already using 4G VoLTE though. Same sim card.
I would contact AT&T advanced tech support as there may be an easier way.
4G VoLTE needs to be enabled in hidden settings.

Your AT&T phone? So it's originally an AT&T model that you're still using with them? That's not the same situation that the OP is in

The U is the AT&T variant vs the U1 which is the unlocked variant, correct?

Yup. But OP has a T-Mobile model that they moved to AT&T. There's also no guarantee that a Note 10+ will work the exact same way as an A52. You're also running 3 year old firmware, while OP is fully updated.
So i don't see the correlation.

The old firmware works fine on 4G VoLTE... that's likely not the issue. What is the issue is it wasn't running on 4G VoLTE so it's likely the settings and sim card need updating not the firmware.
Hi All, thought I would provide an update... After spending hours on the phone with AT&T support this week and being frustrated with the AT&T store, I decided to proceed forward with flashing the U1 version. What started this all was last week my son could no longer make or receive calls on his AT&T A52 phone (we ported it from TMobile September 2021). The store and AT&T advanced tech support said there were issues with people's BYOD devices, even though the A526U and A526U1 shows on the supported devices list. The store rep said he's been getting people in left and right that can't make or receive calls, and all they can do is upsell customers to an AT&T branded phone.
SO... my son's phone was on A526USQS4CVA6. Startup screen showed TMobile still, even with the AT&T SIM card in it. I proceed to flash the A526U1OYM4CVB2_ATT that I found from Sammobile. Was hoping someone had just the "U" version but I couldn't find this anywhere. When doing the flash, I used the Home_CSC file (I had to download a patched version of ODIN as it was stuck as setting up connection) and when it finished it would just keep going back to the download screen on the phone and I freaked out. I did some more research and decided to flash again using CSC instead of Home.CSC (I did a backup using smart switch on my PC luckily). This WORKED! I'm guessing because the software version he was on was different than what I was trying to flash too so maybe this is why I needed the CSC for a clean flash (there was no user data file that downloaded from SAMMOBILE).
Now, calls are working on my son's phone again! AND his service provider software version now reflects ATT vs TMB! Man this has been one heck of a journey lol. I've seen numerous forums on google of people having the same trouble with me, their BYOD devices not working. Seems a flash of U1 worked for me, so hopefully this helps others out there!
