AT&T apn for OTA updates. Please help.

I have a carrier unlocked Note 8. I am currently running stock AT&T firmware. I am trying to figure out how to get the OTA updates on my note. If I need to add a different apn. Does anyone know which one if is? Or is there something else I need to do?

July 1st Security Update for Unlocked Note 8 using Sprint

Can anyone confirm if the CRF6 security update breaks anything? More specifically, are the APN settings still accessible? I want to install it, but I am happy with the current state of things. Thanks

I've just updated July 1 security firmware on my unlocked 950U1 and been using with T-Mobile, everything is good including APN settings or adding.

Thanks. I just installed and all is good.

I have the 950u1 on crf6 and I want to flash tmobile firmware on it but it keeps failing any advice

So I am assuming you cant flash a U firmware on a u1 device? Am I correct on this assumption? I figured since you can flash u1 on a u device you should be able to flash a u firmware on u1

I would like to update my note8
Can some assist with the update please. I have CRC4 and want to update to CRF6 using ODIN. Can someone guide me please?

Odin to downgrade Samsung galaxy note 8

Hi,
I have updated my unrooted note 8 to the android Pie but unfortunately I didn't like the new awful UI also I missed some good features in android Oreo. So, is it possible to use Odin to downgrade unrooted note 8. I'm not interested to root it, just want to downgrade it to official Oreo.
One more question, I even liked Android Nougat than Oreo. So is it possible to downgrade from Pie to Nougat using Odin without rooting?
thanks

You can go back to oreo as long as the bootloader is the same.
You'll have to do a factory reset though.
eg.
Oreo firmware: N950FXXS5CSA2
PIE firmware: N950FXXU5DSA2
Notice the 5 before "DSA2" and the "CSA2" that's the bootloader version. So since the pie and oreo firmware has the same bootloader version you can go back to oreo.
You can NOT go back to Nougat different bootloaders.
eg.
Nougat firmware: N950FXXU3BRA8
PIE firmware : N950FXXS5DSB2
Notice the 3 before "BRA8" and 5 before "DSB2" they don't match!
So the bootloader version 5 will NOT downgrade itself to version 3 therefore Odin will give you a failed error message.

To be is a different question . I have a problem, I want flash the rom with pie generic Spain, now I am in Vodafone pie and Odin always say fail, what can I do?, thanks.

What is your csc?
Spain is PHE in multi-CSC OXM
Vodafone is ATL in OVF Csc firmware.
If you used home-CSC and it fails only option is to use the CSC file (this will delete data so backup first.)
The multi-CSC oxm doesn't have ATL csc inside so you'll lose any carrier specific features (maybe???) So do some research first.

CSC Questions
Hello everybody, I've found myself in the position of needing to downgrade from Pie back to Oreo also.
My question revolves around this "MYSTERIOUS" Samsung "CSC" designation, and the difficulties in verifying what I have vs what I NEED
I have an unlocked SM-N950U1 which is currently running on the Verizon network in the United States
I do NOT have any of the Verizion specific features, ie.... "My Verizon" or even "Verizon Visual VoiceMail"
the phone has also been on the AT&T network previously again with no carrier specific features there either.
Since the "secret code" for the dialer didn't work to reveal my CSC, and there is no carrier software version entry in my about phone software information to reveal the CSC either, I downloaded one of the generic "phone info" apps and it reports VZW as currently active CSC on the CSC tab, but then on the firmware tab in the CSC version location its reporting "N950U1OYM5DSC1" and I have found zero reference to an "OYM" CSC anywhere.
I have downloaded both the PIE and OREO variants of the "XAA" firmware for my Note 8
Does anybody have any idea if this is going to be the correct firmware to accomplish this downgrade without bricking this darn thing, I have no interest in root nowadays because the minuses out weigh the pluses and I really don't want to trigger knox and loose google pay or any of my banking apps, but I really do use and need to use the call recording capabilities that still worked in Oreo, and not anymore in Pie
Thanks in advance

Hi, i just came to this conclusion! i am currently running N950FXXU7DSJ1 and odin always gives me error when i try to downgrade. no matter newest or older version. so there is no possible way to downgrade?
What if i unlock bootloader(if its possible for currently last version), change to custom recovery and install any custom rom(nougat?) and maybe flash bootloader via custom rom also? will this option be possible at all?

Downgrading to oreo help

I'm trying to downgrade from one ui to oreo to get photo editor Pro back on my device but I'm struggling to find the correct firmware on sammobile, my model number is SM-N950F and I'm in the UK on virgin mobile network (who use EE) so not sure if I use the EE firmware as the only match I can see in the phones settings is under Service provider SW ver. Where BTU is written multiple times and UK BTU is an option in the firmware list. Just don't want to flash the wrong one. Any help appreciated.

You should be okay using the LAST oreo firmware for BTU.
Since you said you have multiple BTU like this:
BTU/BTU/BTU
Dial *#1234# in dailer and look at the CSC: line if you see "OXM" in the n950FOXM.... then you have a multi-CSC firmware. So you'll can use the BTU with the multi-CSC OXM.
Just be on a cautious side going back to oreo needs a factory reset! So BACKUP first!
What does the photo editor pro do that the regular photo editor in PIE doesn't do?

Flashing provider's firmware to U1 but CSC does not change

I am trying to flash ATT's firmware to a U1 or U phone but CSC does not change. In software details I see XAA/XAA/XAC while I should be seeing ATT/ATT/XAC. I am on CSL1 firmware (android 10).
Did samsung change something in Android 10? I have done that in S8/S9/note 9 and I never had problems

i flashed the XAA U1 on my S9 and its showing AIO(Cricket) in my software from service provider area and it did this as soon as it saw the SIM

Do you have VoLTE and Wifi calling on U1? I am flashing the U from AT&T just because I want the wifi calling and VoLTE. In U firmwares I see that CSC does not change now

I don't get why I can easily get WiFi Calling and VOLTE with the unlocked version using Verizon or TMo but not with AT&T... Very frustrating as their signal is awful inside my home...
I finally switched to Verizon for service but should not have too.
Hope you can make it work!
