ATT Stock Oreo Firmware

Hi Everyone,
Can anyone point me to a download link for the stock AT&T Oreo firmware for the s7 edge. I found a few but the AP file is coming up as a zip. Even after I rename it to follow the meta.md5 filename odin gives an error which states something about binary mismatch. I dont really want to go back to the unlocked firmware because I will loose the stock ATT& features.
Thanks for the help!

It's not just a name it's an extension you can't just rename it.
Use the samfirm app from xda for a better download rate.
Put it on automatic and decrypt download.
Model SM-G935U
ATT as region code for att firmware.
When you click check update it should say this
G935UUES4CRG3
That is that latest firmware for att.

Hi,
I did change the file extension as well not just a simple rename. Ok I will give that a try. I thought samfirm was discontinued? Also if i download the SM-G935U that is just going to be the unlocked firmware isnt it? Sorry still new at this.

depends though, if your model number on the back of your phone is sm-g935a or sm-g935u
att has 2 different phones
both have att branding and wifi calling volte and apps
as long as the firmware you install has the csc ATT then it should be fine.
if you have the 935a then you can download at the att sections of the forum.
Samfirm may be an old tool but it still works as intended
if u have the 935a just change it to SM-G935A in the samfirm app.

Can't I just install a g935u firmware on a g935a phone?
I just don't want to keep AT&T apps.

BL5 Firmware?

Im trying to carrier switch my U1 to ATT, but my U1 is already on BL5. A quick search of ATT tells me that the latest FW is currently G950USQU5CRG3 as cited here https://www.att.com/devicehowto/tut...3?make=Samsung&model=SamsungG950U&gsi=iqel_vM
Does anyone know if this FW is leaked for download? Or if I flash the sprint fw with this build without userdate if the att bloat will install based off my sim? (i need carrier features)

You can flash CRF5 still and be fine. The bootloader didn't change and that's what matters.
If you download it from updato.com and download say, the VZW labeled firmware it will essentially be the same as all carriers are included. When you flash it, sensing your sim card's carrier it will install the proper files.

[Q]Can Unlocked Phone Use Any Carrier Rom?

Hello, i am using ATT Galaxy S8 SM-G950U Unlocked Phone. When i am going to search any new update or firmware for my phone, i rarely find them even in sammobile I find most T mobile, verizon, sprint updates or firmware than ATT. So can i use other carrier rom for my device Or i have to stick with this ATT? Currently im using may 2018 firmware for my device. I searched a lot for newer firmware but couldnt get any. And can u tell me when the pie update will come for this device.

Other firmwares will work you might just be missing features like WiFi calling. I don't know the exact dialer code but they is a preconfig dialer code to select csc so once you got the latest you could try that. All the firnwares are identical for each us model you wont brick from flashing another carriers

So thats yes right? I can use other carrier rom without any problem?

please some one answer... my device is att s8 smg950u. so can i use smg950u1 firmware to flash 950u?

As long as it's unlocked. A g950 u. U1 and w all can use any csc from carrier firmware. Pop your sim in and flash your carriers csc from firmware

My phone is G950U but it's made in China and works fine with Bulgarian SIM. I have no info about the original carrier. CSC code is TGY, can I flash G950U1 with CSC XAA (Unlocked)?

Yes, the thing is I don't have my carrier CSC available for download since I'm using it in Europe. Wondering if I need to revert flash how to source TGY (Hong Kong) factory rom? Seems all available for download are US-based CSCs only.
My main concern is OTA is currently failing completely, I am hoping to restore by moving away from the TGY code, does that need carrier switching process or just flash 950U1 on top including user data ?

Im pretty sure u1 model pretty much is csc-less i would try to flash the u1 firmware directly and flash the home csc in u1 firmware which should leave it open. BL" "AP" "CP" "CSC" is all you should flash. User data would add a carrier. If you dont it will leave it open.....
If updates are all your lookong for. Just use odin to manually update

I tried 950U XAS and 950U1 downloaded with SamFirm and all versions of Odin but all failed . Strange my S7 from Verizon is able to use OTA in Bulgaria but not this Hong Kong S8.

You are either using the wrong odin or a older firmware.
Or. To flash unlocked firmware you must first flash the combination file then unlocked firmware.

unlocked G950U CSC/update confusion

Sorry for a noob question. I haven't been here since my days with an S3.
I pick up an supposedly unlocked G950U on ebay a week or so ago. When I got it It had G950USQU3CRE9 from 6/18 firmware installed. I put in my Mint Mobile SIM and it worked and had no carrier bloatware, but would fail when doing a manual update. Strangely in settings the Service provider SW ver. section was absent. I downloaded at installed via Odin G950USQU5CRL2. Magically the Service provider SW ver is now in settings.
Trying a manual update it downloaded and installed G950USQU5CSA4. SWEET. But I'm confused why I recieved that update.
Under Service provider SW ver it now lists;
SAOMC_SM-950U_OYN_XAS_OO_0075
xxxxxxxxxxxxxxxxxxx
XAS/XAA/VZW
Who am I getting the update for? Sammobile doesn't list SA4 for CSC's XAS (unknown) or XAA (unlocked) but does for VZW
The Phone ID app lists my product code as SM-G950UZVAXAA
Am i getting the update for verizon but a XAA unbloated one? or what? I would think XAS would be my active CSC.
Confused .... My last time playing with phones CSC didn't exist and I can't figure it out.
Also, I would love to flash the G950U1 firmware but there isn't a version a current as SA4, even the pie betas, and concerned about a brick.
Any help in understanding would be GREATLY appreciated.

Xaa is unlocked firmware. I think xas is sprint. But the third vzw means your sales code is verizon so you should be getting updates from them. You can use sammobile or updato get the latest and flash home csc with your sim in and it should go to your carrier. 5th digit from end is bootloader revision thats what you have to pay attn to. As long as you get revision 5 firmware ypur gold. We have locked bootloaders so you cant really brick with odin. You have to flash a rev 5 combination file then the u1 firmware which is the unlocked firms
So what i think is you got a sprint phone with unlocked firmware but with verizon as a sales code for end user if im not mistaken... If thats the case it is most def unlocked sim wise.

I have a couple of noob questions as well Since I'm new to CSC era...
Got s8 950U and was not able to update FW for several months now due to no functioning OTA and Odin failed as I lack the combination file knowledge. My phone appears to be for Hong Kong market with Snapdragon and I use it in Europe.
1) Is it possible to unlock OTA by switching CSC to local provider? Not sure if 950U is even supported in Europe CSCs? What if I pick XAA instead of local one?
2) Any idea how to update to Pie and unlock OTA/Samsung Pay/Secure folder etc.? What is the correct formula to understand which combination file to use before flashing latest Pie 950U1 XAA ROM G950U1UEU5DSC1?

Nobody able to help at least slightly?

i have the same problem with my s8 , thar has csc of hong kong tgy and won't me let download the last updates also i can't open samsung health secure folder s pay ect....any solution ??! ,, thanks in advance

I have the same issue. Phone name is SM-G950U but CSC is TGY (Hongkong). It can not be updated via OTA and I don't know what is its correct CSC.

SM-G950U switch to Unlocked ROM?

I have a Sprint Galaxy s8, but I am no longer on Sprint.
Is it possible for me to flash the unlocked ROM, effectively making it SM-G950U1?
My current build nnumber: R16NW.G950USQU5CSA4
I'm hoping when it's available I can flash to the Pie version of G950U1.

Only if Sprint unlocked the device through uicc unlock. If you flash u1 on a locked it's still stuck to the original carrier. As for guides there are several guides in the general section for carrier switching

Yes it is. I just did it yesterday. I was on G950USQS5CSB1 and didn't get wifi calling or VoLTE on Mint Mobile but after flashing G950U1 I now have them.
Since you say you are no longer on Sprint I assume you just want the unbranded G950U1 firmware.
Using samfirm on your computer putin G950U1 as phone and XAA as CSC and search. You should get G950U1UES5CSB2. It is the latest and has the same bootloader as you. Download it.
Download and use the 3B modded version of Odin.
Back up your phone as it will be wiped.
study here how to use Odin..... there are many guides
Use the CSC file not Home_CSC.
Have the sim of your current carrier in the phone when you flash.

This is exactly what I'm doing. Switched to Mint, but don't heav Wifi or VoLTE. Glad to hear that G950U1 works with both those (was worried I would have to flash TMO to get it).
Thanks again!
