Installing NON-AT&T FW on SM-J320A... Possible?

I have the SM-J320A, AT&T version, and now being used outside the USA. Specs on GSMArena indicate that this phone is one of the versions of the J3 2016 family: J320FN (Europe); J320F (EMEA); J320F/DD (India); J320A (AT&T); J320P (Sprint, Virgin Mobile, Boost); Galaxy Amp Prime (Cricket); Galaxy J3 V (Verizon); J320M (LATAM); J320G (Asia).
1. So does this mean all these versions are identical in Hardware?
If there is no other option, I will install the AT&T newest version, however I would prefer to see if it's possible to use a non-AT&T FW so I can get monthly updates. So...
2. Can anyone tell me if it's possible to put a NON-AT&T 'open' version stock FW on the SM-J320A... and I would then be able to receive the security updates direct from Samsung...
Hope what I am asking is clear.

The j320 model has three different soc. The j320a is exynos based. The different exynos models are J320a, j320ag, j320az & j320w8.
But with this device only the carriers supply updates, unfortunately.
Not sure if it's an option, but I activated an att sim for their prepaid service (25¢ per minute or something)... Will never use the $10 I spent for the service, but I can update ota now.
Other than that keep your eyes here, we try to keep the latest firmwares available for download.

That's the best answer I've had on a forum... That makes it clear. So since I cannot really do what I was asking, no problem, I am willing to install the AT&T 7.1.1 version J320AUCU2AQI5. Only issue now is that as said, the phone is in use outside the US currently so cannot get the OTA DL. Is there any way or source to DL the full stock firmware for flash via Odin? Would prefer fully stock version with no rooting, etc.... I have a Macbook Pro for the flashing if it makes any diff.
Robert

Maybe this is what I'm looking for...

Ok thanks again...
Is that completely stock and flashes with Odin?
Any other special instructions needed to flash?
Just asking as it seems there is a lot of discussion on the entire thread and I'm not sure which issues are coming with which downloads.
Robert

Any issues where addressed.
Yes 100% stock.
Nothing special just load all four files in odin and flash it

Forgive me if I sound like a real dingba5, but I can't control myself from asking this. I have developed what can only be described as an unexplainable and illogical obsession with altering my Galaxy Express 2 SM-J327A 's factory condition. From what I know, there's no custom recovery, no ROM, no ROOT. NOTHING for this model. But the Sprint, Boost, etc. variants are all living it up in zip flashing heaven.
So using the same logic my man was using here, which was making sense, could I flash J327P firmware onto my device without ruining my day......

Have a SM-G930V. Want to flash but have no idea what to do.

Hey there, hope y'all are doing well.
I recently purchased a Samsung Galaxy S7 SM-G930V, Nougat 7.0 (note: I live in europe, and it's an unlocked phone). I want to get rid of Verizon logo while booting and all the unnecessary apps connected with Verizon. Plus, as you know Verizon locks some functions like the device maintenance, turning off the backlight of the capacitive buttons, etc, etc.
So, I'd like to have a clean/untouched samsung firmware without any useless apps.
Is androidfilehost.com trustworthy? what about updato.com? (the latter had slow dl speed, and I stumbled upon the first alternative)
PS. by the way, mine reads G930VVRS4BQI1, so one thing that confused me was while loking up for files to download; should I get the G930VVRS4BQI1 which may be the only compatible file for my phone, or do I already have G930VVRS4BQI1, so downloading it would be useless?
Since I wouldn't like to tinker often with the phone system, what do you suggest, flashing or rooting?
Is there any guide for my case for flashing?
I noticed these two on the front page:

which should I pick?
and since the posts were last edited in may and september, where can I find the latest firmware?
and after doing all this, will everything work well, will I get OTA updates?
I would really appreciate someone helping me out, whenever you're free.
Thanks in advance

You can actually cross flash any Qualcomm s7 firmware between all carrier handsets. With your case being in Europe I would recommend the sm-G930U firmware. Which is the carrier unlocked variant of the S7 stateside that has all bands unlocked that the modem is capable of. You will recieve OTA's. It's Odin files are on Updato and SamMobile. AndroidHost is trustworthy.
In your case of not wanting to tinker or have a "need to have" rooted feature on the new device, I would flash the the 930U firmware and enjoy your new non branded system.

Hey JediDru,
I also just bought the S7 Verizon variant, and am planning on using it on MetroPCS. Would you recommend the 930U firmware for me as well? I wouldn't mind getting rid of the Verizon bloat before I hand it over to my wife...

You very well could. I think there is a thread around here specifically about metropcs setup somewhere between the verizon s7 and tmobile s7 forums. I use my 930v flashed to 930U on tmobile.

hey there, thanks for your advice! I downloaded the latest file from here. sammobile"dot"com/firmwares/galaxy-s7/SM-G930U/VZW/
In a moment I was clueless at the "pick country" since there were more than one USA options. so I went with verizon, since my phone comes from verizon.
In the link I mentioned above it reads this This is for SM-G930U from USA (Verizon) which makes no sense to me, how it can be both "U"-unlocked and verizon at the same time... but, oh well, I flashed it 4 days ago and I've encountered no problem, which is all that matters! Hope I made no mistake at picking that file.

Recently purchased galaxy S7 SMG-930V (Best buy version) from a private owner.
I am on cricket and on APN setup LTE and MMS works without issues. Only issue is that upon dialing USSD code i get 'Connection problem or Invalid MMI code' . I tried all options available mentioned in this forum still doesn't work. Which version of SM-G930U should i flash? Main reason i purchased the phone is for Samusing Pay. Don't want to brick or lose Samusing Pay option after flash.
Inputs are appreciated.

Did it remove all the bloatware from Verizon?
Does Samsung pay works?

Yes Flashing the G930U firmware removes all carrier bloat.
Samsung pay comes with the U firmware.
The last time I was on the U I had bad standby drain. I read somewhere else it has to do with the U not dozing correctly. They may very well have fixed it now, I'm on the latest tmobile 4BRA firmware and it sleeps like a baby right now.

Flashed the verizon U firmware and it did remove all the bloatware. Still need to check on battery drain with Samsung Pay. All other apps are in "Always Sleeping Apps" for better battery performance.
For future reference make sure before flashing new firmware google accounts and lock screen securities are removed/disabled.
Is there a way to back up apps with user data and home screen and reuse instead of installing all over again when a new firmaware is flashed. Spoiled by the root and titanium full back. That was so easy.

As far as I know, no. It's not so bad. I had gotten into the habit of taking screen shots of my app drawer and redownloading. To think now I can just redownload the configuration of apps I had before is as good as it gets. I still just redownload. I like to re-set everything back up just so I know its done.

I haven't tried this method but to backup and restore all installed apps check this Link.

Actually, if all you want to do is switch carriers (same GMail address), then a firmware swap will work.
I have an ex-Verizon (blacklisted IMEI - previous owner)S7 that I was moving to Tracfone (which uses both VZW and T-Mobile towers) - naturally, VZW was a non-starter; however, the UnCarrier was fine, so I used a T-Mobile nanoSIM (Tracfone triple-punch SIM kit includes SIMs from all except Sprint) and replaced the VZW firmware with T-M firmware (Prince Comsy ODIN does the track rather neatly). As long as your IMEI is not blacklisted from the TARGET, such a swap will always work.

S7 Edge G935P issues Flashing Supposedly compatible G935U Rom

Hello Everyone I understand that this would have been better posted at the Roms and development Forum but it would not let me post because of some anti-spam thing. Anyways I was told that I could Cross flash the g935U rom on any variant of the S7 edge so I tried to install it the same way I installed the Stock Sprint G935P firmware. When I was flashing the flash stopped and locked up. The phone has a error on the screen saying SW REV CHECK FAIL : [aboot]Fused 5 > Binary 2. Any help would be appreciated. Attached is a picture of the screen and the Odin Logs.

Ran into the same problem. It seems Sprint decided to switch to binary 5 on the QL1 firmware while the rest of the carriers didn't and stayed on 4. I have been looking all over for a way to root my SM-G935P on QL1 firmware and have found nothing. Looks like we're SOL for now thanks to Sprint.

So We Need To Wait For The Android Oreo Update or just wait for G930U To Update The Firmware

You rooted SM-G935P on G935PVPU5BQL1 firmware? If so ...... Yes please show me the way. Been trying to figure it out for quite sometime.

can you downgrade to the previous versions of marshmallow and them rom over to 935u?
you will have to find the previous boot loader file and flash all 4 together for it to work.
just a guess. ill do some research.

Was going to do the same thing after getting a good deal on a pre-owned s7edge from BoostMobile. I had no problem getting the sim unlocked for MintSim(MVNO-Tmobile), and it seemingly works fine after setting APN settings. I'd prefer to not have the g935p firmware. I'm assuming if I can somehow switch to g935u I'll be able to use it more comfortably for both verizon pre pay and MintSim? If there is a way to downgrade to the binary 4, I'd like to know as well. As far as I know I'm still able to use Samsung Pay, so I'd like to keep that option open.

Only thing we can hope for as of right now is that the oreo update is binary 5 on the U firmware. But I dont see that happening. Think thats a new exclusive for sprint to keep people tied down. Hopefully im wrong....

On a more positive note, the bootloader binary has been updated across carriers with every major os upgrade.

I think the same. Sellers were selling S7 and S7 Edge models with U firmware for international use, no sprint apps, logo or restrictions and maybe sprint was losing customers and they decided to update the binary to avoid this situation. Really I prefer the U firmware instead Sprint or Verizon stock rom

On the Oreo update? I havent even checked.

Hasn't been released yet, but it has happened from MM to Nougat. Just speculating that it will happen when Oreo drops.

Switching carriers with bootloader v2 not possible?

So I'm trying to change the carrier on my galaxy s8 SM-G950U, which is an unlocked AT&T S8, but I keep running into "sw rev check fail" when flashing the files. I read that it could be my bootloader version causing the problem? I looked at my baseband version and it says G950USQS2BQL1, which I guess means my bootloader is version 2. So I was wondering, is it not possible to change carriers with a v2 bootloader? Sorry I'm kind of new to this so don't really know if this is a dumb question.
Thanks in advance
EDIT: nevermind, guess I'm just dumb. I quickly found this thread after posting this question, which gives you the Bootloader v2 files https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817
The other guide I was using didn't mention bootloader v2 at all, so I guess it was slightly outdated.

Or just read what youre flashing. Don't flash old firmware. It's been v2 for a few updates so you were trying to flash old firmware. Use fw.updato.com and search for G950U (Carrier files) or G950U1 (US Unlocked version). Sort by date so the newest ones are on top and stop flashing old ****.

How to make my unbranded Samsung Galaxy S8 work on ATT again. Pls help!

Amin, Rajan - GCIB NY​
11:06 AM (0 minutes ago)
to me
I have an unlocked/unbranded Galaxy S8 (SM-G950U1; Baseband is G950U1UE8DUG4). I was using it on ATT but now it doesn’t work after ATT 3G upgrade. I have read that I can flash G950U firmware to my U1 phone and it will work on ATT.
Is it any G950U firmware or do I need a specific version for ATT and my region? Can you show me where to find the needed firmware?
Can someone walk me through steps on how to install the firmware (including where to find Odin and any other downloads I need).
If this will wipe my phone, is there anyway to back up my phone so that I can get all my contacts, text history, whatsapps history, apps back on the phone after flashing it? Can you also walk me through how to do this?
Will this actually work even though my IMEI is staying the same – ie even if I change the firmware, wont ATT know that the phone was not originally an ATT branded phone and thus it wont work no matter what I do?
Lastly, the only reason I am doing this is bc I really like my Galaxy s8. But the S8 only goes up to Android 9. What are some of the issues I could get using phone that only goes to Android 9? (For example, could it be that I wont be able to download new apps if they are programed for Android 10 and above)?
Im a total newbie to this. I hadn’t even heard of Odin until yesterday so please make the explanations for someone is not a tech person.

At selected Best Buys the Samsung Experience center can flash it for you.
I don't flash my Notes... as I don't wish to potentially contribute to the bricked phone threads here.
At least not yet.
