A question for the experts, i need help with a S8+ with 2 findings of model number - Samsung Galaxy S8+ Questions & Answers

Hi everyone,
I bought a S8+ 3 years ago for my wife when we were living in China. They told me it was a US version with 1 SIM slot. It worked well for the years and had some chinese preinstalled apps, but it had google (China has some legal issues with google so most of the phones don't come with google apps installed or allowed).
Today, I did a factory reset to it since I got another phone for my wife and I want to use it as my work phone and I realized Its still on android 7 (tried updating the software in the phone menu and it says it up to date but still on android 7)
I checked the phone and software info and it says:
-Model Number: SM-G9550
-Hardware version REV1.0
-Android Version 7.0
-Samsung Experience version 8.1
-Baseband version G9550ZCU1AQEE
-Kernel version: 4.4.16-11449429 [email protected] #1 Wed May 24 14:13:30 KST 2017
-Build number NRD90M.G9550ZCU1AQEE
So then I decided to download Odin and the right firmware from sammobile since they have official ones for Samsung. I downloaded a SM-G9550 for China Android 9 Build date Mon, 19 Oct 2020. I tried flashing it but it says it failed. It didn't do anything to my phone (at least it didn't brick it nor it should since I checked everything to make sure)
Since this is not normal, I decided to go check the version when I press the buttons Bixby + Vol. Down + Power and found the following info:
-CARRIER: ATT
-RPMB fuse blown
-RPMB PROVISIONED
-CURRENT BINARY: Samsung Official
-SYSTEM STATUS: Official
-FRP LOCK: OFF
-WARRANTY VOID: 0X0
-QUALCOMM SECUREBOOT: ENABLE
-RP SWREV: B1(1,1,1,1,1) K1 S1
-SECURE DOWNLOAD: ENABLE
-DID: 205E5F695E33
At this point i'm concerned in why does it says carrier ATT, so I checked the menu when pressing the buttons Bixby + Vol. Up + Power and the following info is displayed on the top:
-Android Recovery
-samsung/dream2qltesq/dream2qltesq
-7.0/NRD90M/G955USQU1AQEF
Very confusing for me, since I never encountered this before. And I assume my phone as been rooted.... since I searched what dream2qltesq was, and its for rooting the S8+. Sucks.
Now i'm concerned and don't know which model to flash (G9550 from China or G955U from US)
Can anyone help me with this problem and some questions that I have:
1- I want to flash a newer version, which one should I download and flash then? (G9550 from China or G955U from US) (I don't need any of the chinese apps, never used them)
2- If its ATT carrier, will flashing to a G955U version of ATT lock my phone?
I just want my phone to work well with newer version in English with google in a Official Samsung Rom for S8+.
Really appreciate beforehand any help.
Thanks!

My Questions are where is this firmware from, is it safe to use ?
Seems to burn through the battery fast.
Smart switch didn't work correctly, what could I try as alternative (Old phone is S5)
Is there a better custom firmware I could use?
Could this have been done to get around a blocked IMEI ?
Would it be safe to Flash a Stock firmware, will it still work, what firmware would I use ?
Location is Australia and Network is Telstra.
Thanks
From what details you have presented that is a fake device, I would advise you return the phone immediately.
It's running Android Lollipop (S7 only has Android Marshmallow firmware) It seems it's got a 32Bit SoC; the S7 is 64Bit.
Hope she didn't pay more than $100 for it, because that's how much those fake ones are worth.
Yep paid almost top $$ for it, from an area I don't care to go back to
Don't know there even were fakes out there I'm guessing the camera is crap compaired to the real one also
Nobody has ever seen a 64G dual sim model in the wild. Sorry man.
oh man... that one is a fake S7

[HELP] S6 with wrong firmware (Edge?), no s/n, among other problems...

Hello!
I've recently acquired an used Samsung Galaxy S6 (SM-G920P, but in Download Mode it says G920R4) and I'm trying to go back to the stock firmware. That being said, I have no access to the original box, neither to the vendor, since it was bought in Vietnam and I'm now in the other side of the world.
The phone was initially rooted and I tried to unroot it so as to have OTA updates. Turns out it seems to have no S/N, and the one it does have in the Settings is seen as incorrect by Samsung Smart Switch.
ODIN fails to flash any G920P firmware in it. (Complete (Write) fail)
I have reasons to believe someone also tried to flash it with Edge's firmware, since I managed to access the menu for its side notifications. Is there any way to solve this? I'd need the phone to work in Vodafone's network, since it's the one I'm using...
The phone is working perfectly as it is, so if there's no going back, I can leave it like this. I'd just really like to have updates.
Please bear with me, for my knowledge of these matters is basic. I've looked around for days for an answer for this before posting.

Galaxy s7 "updates software" option missing

Hi, I have just bought a brand new galaxy S7, model SM-G930F.
Although it is an international model, it carries a snapdragon 820 processor.
I am told , that it is a USA model, built under Verizon.
SM-G930F is supposed to be a global model with exynos, does anyone knoes what is the phone I bought?
Anyway, my real problem is, that the "updates software" option is missing, in "about phone" list.
I am stuck in android 6.0.1
I checked it is not rooted and it must be a genuine phone.
Can anybody guide me through solutions?
I would really appreciate any help.
Thank you
Moving to general S7 Q&A since you say it's a SM-G930F.
Check the back of the phone and verify the phone model. You should be able to update through other options like Kies, unless they've changed that recently.

It's not a G930F if it has a Snapdragon processor
Commonly faked to look like G930F by editing firmware / stickers / model numbers etc, more likely to be the G930V if it's Verizon
Boot to download mode and check the model number in there, that's the only one that can not be faked
(Volume Down & Home & power)
And they likely removed the update option from settings to prevent any problems of the phone updating to either the wrong firmware, or removing their fake edits with a V update
Flash the proper firmware with ODIN 3.12.3 or newer from updato.com once you know your model S7
Galaxy s7 "updates software" option missing
Dear Durham,
Thanks for the help.
Yes, you are right; it is G930V.I have been tricked...
I have visited updato.com and found 12 variants of S7 firmware.
My bootlader version is - 6.0.1 November 20, 16 USA (Verizon) (VZW) G930VVRU4API3
Shall I download and install this one and afterwards make a manual software update or
shall I install the latest - 7.0 August 25, 17 USA (Verizon) (VZW) G930VVRS4BQH1 ?
After successful installation, will these firmware fake modifications( to G930F) disappear permanently?
I am much obliged
Thanks

The ROMs from updato.com are full ROMs so you can just flash the latest / newest one and you'll be 100% up to date once it boots
Use CSC and not HOME_CSC though as you are going to want to reset after the flash to clear any hacks from the previous ROM (This will wipe the device so backup any important files first)
CSC, AP, BL and CP
Yes this will permanently remove any modifications from the faked ROM
Wish me luck, I will give it a go!
You have been most informative, many thanks.
Good luck :good:

The good news is that the verizon edition can be rooted and is network unlocked from the factory so as long as ure carrier supports the bands it will still work for you on a side note flash the u firmware not verizon and u wont have any verizon bloatware out of the gate either
Mad scientist, thank you for your intervention.
Just to be clear, which firmware do you suggest me to install, not the verizon G930V?
Could I install the G930F for my country (Europe).
I thought they are incompatible...
As my bootloader version G930V I think I would better stick with the V version.
Are you suggesting not to upgrade to nougat and reinstall factory installed 6.0.1 and better wait for 8?
Yes you are right, I am not good at twiking.Will I have drain baterry issues with nougat?
Dear Durham,
Emergency help!!!!
I installed it succesfully but now it does not recognize my sim card, as it is from a non USA country.
Should I reflash a different firmware? F or U ?
I am from Greece
It seems to be working...
The Verizon logo appears upon starting the phone
But in language selection, there is only English and asian languages available.
Software update finally appeared.
In order to have my langage back, should I reflash with the U ( unlocked version) or the F (global)?
No mobile data.
Maybe I am calling through Verizon.Roaming.Expensive.Scarry...!!
He means that the G930U firmware will flash fine on the G930V, it is the same firmware but without the Verizon bloatware added
You can not flash any other firmwares, it just happens that those two are compatible with each other
Flash straight to the latest
So I shall flash the G930U?
Will my sim card be recognized and mobile data be active.
Nougat 7 or MM 6-your opinion, again?
thnks
No idea if your SIM will be recognised, but if it's not working with the V firmware it's worth a try
As I said, flash the latest firmware which is Nougat
Personally I would be contacting the seller and asking for a refund / exchange for a real G930F that you paid for
firmware
I tried, but he is not cooperative.
How about F version-it worked with it before ?
(only it was modified with the dissapearance of system update.)

No you cannot flash any other model firmware, that was NOT the G930F firmware, it was a hacked / faked U or V firmware
I think you better read a good few threads before going much further or you're going to end up with a brick
Contact the seller and request a refund
Don't suppose you can flash CSC files of the 930F on 930V?
Dear all,
Thank you for your help and interest in my problem.
This is indeed a great forum!!!
I tried to flash the F version, but thankfully odin stopped it from the beginning, presenting "failed" message.
I suppose if it continued, I would end up with a brick as Durham suggested.
Finally I flashed he U version, as mad scientist suggested, and up to now it works like a charm.
As Durham advised, I used CSC and not HOME_CSC and the hack was eliminated.
Sim card is recognized, no bloatware and mobile data working.
Let's hope it will continue like this...!!!
Only glitch, not everything is in my home language ( message icon name and in settings-the menu options-any idea how to fix it? - I removed english and left only my language as selection, but onle these remain untranslated)-small problem
I have learned a valuble lesson from my adventure.
Ebay, an organized platfrom may it be, it cannot control each individual's deceivals, so one must be extra wary when buyng from unofficial sources, nomatter good reviews from others...
Thanks again to you all for your help, I would be in serious position right now, if it weren't for you guys.

Refurbished Galaxy S8+ running Note 8 firmware?? I just want to flash my firmware...

Hi everyone. I have a Galaxy S8+ that I bought on BackMarket a year ago. The phone has been great, but has always had problems with some phone calls going straight to my mailbox for no reason, texts not coming in then suddenly working if I send OUT a text. After some research and contacting my provider (United States, Ting), I was told that this is because I need to enable VoLTE. My phone didn't have the option to do so and when I called Ting again, I was told that this is because my phone was the International version and VoLTE wasn't supported on that model.
I thought that was the end of it, but this week I had the thought that maybe this is a firmware thing instead of a hardware thing. Calling Ting again, they checked my IMEI and said my phone should be able to do VoLTE. Great! All I needed was Odin and the right firmware (I was thinking G955U1, TMB). So here's where things get weird. As I started to set up for flashing my firmware, I gathered the following info:
IMEI.info says I have:
Model: G955F Galaxy S8+ (SM-G955N)
Here's the info I get when running the "Phone INFO ★SAM★" app.
Phone Model: SM-N950F / Galaxy Note 8
Firmware's CSC Code: XEF
Bootloader Version: G955NKSU3CRI3
PDA Version: N950FXXS5DSC6
CSC Version: N950FOXM5DSC1
Latest Firmware: N950FXXSDDTJ1
If I'm reading this right, it looks like I've had a Galaxy S8+ running Note 8 firmware? At this point, I'd still like VoLTE, but even moreso, I'd like to just know what's going on and what I should do about it.
Seems like somebody installed a modded Samsung firmware on your phone. Check download mode for KNOX, I think it will be tripped (0x1).
If it is tripped then no Samsung Pay and stuff that depends on KNOX. If you are fine with that and just want to get VoLTE working, download the right firmware for your device and flash it to stock. If stock everything is important to you, I suggest contacting the seller on BackMarket and getting a refund or something if the seller didn't specify tripped KNOX.
BTW, if I remember correctly G955N is the Samsung direct model sold in Korea, so depending on CSC and what not VoLTE might not work. Best of luck
Thanks for the reply.
So I ended up solving this with the help of a few people over on Reddit. Here's what was going on and what the solution was, for others that come across this.
The phone was running v6 of HadesROM. I guess the creator of HadesROM uses the Note8's OS build as his base for the Note8/S8/S8+, which is why the phone was showing up as an N950F. And the phone itself was a G955N, which is a Korean model.
At the direction of a few people on Reddit, I used TWRP to re-flash with the newest version of HadesROM and set the Firmware CSC properly to a US Carrier.
When the phone booted back up, the VoLTE setting was present in quick settings and works great.

Question A226B - Bricked - Brom only - AuthBypass ok - Cant flash Roms

Restructured my previous thread that was rushed to include all that I missed.
I bought this phone second hand from a friend with a smashed screen, I replaced the screen and it had a password so I blanked it using buttons (mate wasn't happy to give me password there and then) *and my impatience got me.
I thought I could OneClick it through test point since it was (still is) opened.
I wasnt getting anywhere with FRP removal, then I think I pressed All + Dload with just preloader selected or something.....
Since that it just loops on Brom no download mode etc
I can still bypass protection and get it to flashing point but no matter which firmware I try, It errors from U1 OS11 to U5 OS13.
Two errors are:
1: ANTI ROLE BACK
2: STATUS_SEC_IMGHDR_TYPE_MISMATCH (0XC0020029)
I've included below my Model which I pulled from IMEI checker.
WIlling to pay and teamview for someone to fix if it comes to that.
