SM-N950U Software Update Problem - Samsung Galaxy Note 8 Questions and Answers

Hello everybody.
I bought a refurbished N950U and I have a problem but the seller unfortunately doesn't respond. When I disconnect the data, the warning "You won't be able to use any apps that require an internet connection unless you use WiFi. Cancel / Turn off" appears every time. Samsung USA told me that the cause is the old FW; in fact it has the N950USQU6DSH3 (VZW). However, an IMEI results in a T-Mobile (TMB). I would like to install N950USQS7DTA5 (TMB, USC) simply with Odin. In this way, however, I'm afraid to lock it SIM/Region because I believe that the UK Seller has modified the FW before installing it to unlock it and if I overwrite it becomes SIM/Region locked. Correct? I don't know about American models, is it possible to update it to the latest FW simply with Odin (downloading everything from sammobile) and keep the device sim/region Unlocked ?
PS: software updates option seem locked (I think because of FW seller MOD otherwise device becomes locked...)
Thank you a lot
Best Regards

There isn't a model number, there is only
SAMSUNG
Galaxy Note8
But, I'm sure it's a SM-N950U also the IMEI check confirm it

It should have a model number printed on the back.
I ask because I have seen a few posts now of phones that have parts from different variants, where it will say N950F on the back but the software is N950U, where trying to flash official filmware could brick the phone...
I'm not sure what to advise you, hopefully someone more knowledge will answer you.

Download phone info (Samsung) app from playstore.
Check the Hardware tab and check out the "Hardware/Board" and GPU.
If it says for eg, Samsung exynos 8895 and ARM MALI-G71, you have SM-N950F/F-DS/N
If it says for eg, Qualcomm SDM835 and GPU Adreno 540, you have either SM-N950U/U1/W or SM-N9500.
Any Mediatek cpu's you got a fake note 8.
You can also check your firmware that you are on.
BL, AP, CSC and Baseband first 5 characters has to match eg:
BL- N950U.....
AP- N950U.....
CSC- N950U.....
Baseband- N950U....
Edit changed cpu and gpu for note 8 Qualcomm chip.

From software info option on the phone I see N950USQU6DSH3 (region VZW from IMEI.info)
Phone info:
Hardware
qcom/msm8998[64-bit]
msm8998
GPU
Qualcomm Adreno 540
It could still be a fake ??!!
I'm very afraid because the uk-seller seems very suspicious
However what I would like to know is what I wrote in post 1
Thank you

It's real!
You can flash the T-mobile firmware N950USQU7.... that you want on it.
NAKE SURE PHONE IS REGISTERED TO YOUR GOOGLE EMAIL AND NOT THE OLD USER OR YOU RUN INTO FRP PROTECTION! BEFORE CONTINUING!
You can log in to your google account to see the devices that are attached to you on PC. (Google account the you log into playstore when you setup a new phone and phone gets attached to that account).
If still attached to the old user and you do a factory reset FRP will lock phone and ask for the old user google email to unlock it. So make sure it's registered to YOU!
Place the 4 files in Odin
BL = BL-file
AP = AP-file
CP = CP-file
CSC= CSC-file (this will format storage and put phone back to factory! Backup first).
Afterwards check your APN Settings or replace sim card if it is really old or defective.
Use samfirm.exe or frija to download firmware and unzip it.

Ok as you can see from the attached photo there are 2 devices connected one is GN8 so it is impossible that it is also connected to the old user, it's right?
Then If I download the new FW N950USQS7DTA5 (TMB, USC), Odin from sammobile and follow the instructions, is everything all right? I will not get a SIM / Region Lock, it's right ?
Because Samsung USA told me that it is lock by T-Mobile like I though...

Is it true that once unlocked the N950U remains permanently locked i.e. if I bought it reconditioned unlocked with FW N950USQU6DSH3 (region VZW) I can flash N950USQS7DTA5 (TMB, USC) by Odin and the phone remains unlocked? Please help me .....

As for being Carrier UNLOCKED it shouldn't lock to Your Carrier csc. Once its paid off and UNLOCKED by the previous person it should remain UNLOCKED.
You can read the 1rst post in this thread if you want to switch from N950U to N950U1 (not too much bloatware I heard!)
https://forum.xda-developers.com/galaxy-note-8/how-to/guide-sm-n950u-u1-t3685884/page256
Hopefully someone with a US note 8 can chime in!!!

U1 has less bloat. All the carrier firmware is the same doesnt matter which you flash as it will provision to the sim you are using

I did not understand what the SIM/region lock/unlock is in the fw that flashes or it is at another level? Because if it is at another level I think I can flash the newest T-mobile fw that the device remains unlocked, correct?

samsung galaxy note 5 n920f

HI, i had this version and i didn't find any data related to it like firmware , i noticed that everything run smoothly and mobile run the latest update (your system is up to date ) lollipop and model n920f was written on the back although of that when i tried to use Samsung info apk it showed that phone made in Korea and it was Verizon version n 920v so i figured out that phone was a Verizon version and was moved to china to be unlocked and back was replaced also so, am i right ? and if i am right , can i download Verizon marshmallow update without problems.
I thought the f was an international version which hadn't been released. Its usually the tag for european models, which of course wasn't released for the note 5.

I know that it seems to me an assembled version hardware mad in Korea for American company Verizon and was sent to china to be unlocked version so they changed the model to n920f instead of n920v and applied modified soft and kernel and they replaced the back also and wrote n920 f
What do you think bonerp ?

The 'F' variant for Samsung devices is usually for European countries, but Samsung never released Note5 officially in Europe.
There is no N920F, the international variant is the N920C, If the actual device is N920V then those firmware should work.
Download and install : https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo&hl=en_GB
And see what the bootloader and modems are, they should specify what the actual phone is.
Remember that you are responsible for what you do to your device so proceed with caution and always back-up your data.
Here are screenshots from Samsung info apk , what do you think ?

It's a sprint model, you should be able to flash N920P firmware; It seems like the phone is running a custom ROM which has the CSC of the N920V.
Again you are responsible for what you do to your device so make a back-up before you attempt anything.

Depending on phone info apk it showed that model is n920v Verizon but you said its a sprint version i am confused.
how did you know it is a n920p not n920v ?

The bootloader and baseband belong to N920P.

http://www.sammobile.com/firmwares/download/56804/N920PVPU2AOI6_N920PSPT2AOI6_SPR/
It's kind of confusing because your KNOX counter is not tripped but the firmware on your device seems to a mix between N920V and N920P with the Chinese and Sprint CSC

I'll be honest if there was a way to unlock sprint phones that way we'd already know about it, put in a T-Mobile sim and an att sim if they both work it's unlocked you can use any SIM cards if they work it's unlocked as long as you don't use sprint and Verizon for the rest. I'm very confident it's unlocked if it's not, it can be done easily

[HOW TO] Flash U1 firmware to U device

First of all, thanks to Raymonf (I dont know his XDA Username) for making these Odin files. This new version of modded Odin allows for flashing custom and official tars AND also compressed binaries, which Samsung will be using in all Odin firmwares from Oreo on.
Oh and doing this doesnt wipe data if you do exactly what I wrote below.
1. Download your devices firmware from below
2. Enable USB debugging by going to settings > about phone > software info > click build number 7 times and enter your password
3. Open command prompt on your PC and type adb reboot bootloader
4. Open odin and select the AP, BL, CP, and HOME_CSC file in their corresponding locations
5. Start it
6. You are there!
To go back, do the exact same thing with the U firmware files!

The modded/patched Odin has the model-ID and SHA hash check disabled, therefore allowing you to flash an unbranded "U1" firmware onto a branded "U" phone and vice versa.
As of now this works on most US Qualcom (QC) models, but an increasing number of international Exynos (EX) models now include a new RMM security which prevents this kind of cross-flashing unless you first disable the RMM, by flashing an RMM-Disabler package through TWRP.

Probably gives better chance to root huh?
What I'm not clear on is: after I flashed my factory unlocked s9 to the VZW U firmware to see if I could get video calling to work (it didn't) then flashing back to what has been described as stock U1 ARBG firmware, in my about phone it still says VZW/VZW/XAA. Is this set by the SIM. Will this only change when I put a different carriers SIM card into the phone?
Question, before i dive in...
My UICC is locked to Sprint right now (damn 50 day limit) and I was wondering, if I flash this U1 rom, would I be able to edit the APN? Has anyone else done this?

That's correct, the unbranded "U1" firmware sets the carrier parameters based on every different carrier sim card inserted.
Don't worry about the VZW/VZW/XAA, for all intended purposes the phone acts as Verizon phone.
It's just a flag, but if you can't sleep over it then do this while rooted:
adb shell su -c echo "VZW" > /efs/imei/mps_code.dat
adb shell su -c echo "VZW" > /efs/imei/omcnw_code.dat

Flashing the unbranded "U1" firmware will neither unlock the network nor the APN settings if you keep using a Sprint sim.
On the other hand, if you unlock the network and insert an AT&T or Tmobile sim then you should be able to edit the APN, but then again you don't have to edit it because it gets set automatically based on the type of sim inserted.
Thanks a lot, quick question, i have an at&t "U" model, manage to install the U1 software (wanna get rid of all the at&t apps), everything its working just fine, but when an update comes to the U1 model, can i install it the regular way on odin, or do a need to follow this steps again??
here's the link i use from another post to dowload the system a bit faster: https://androidfilehost.com/?w=files&flid=257047 greatings to the author.

I wouldn't blame you lol, yes I know there's a risk. But you have stated earlier that you flashed a firmware and it didn't trip knox, so I'm wondering if you flashed a carrier firmware "U" on your SM-G960U1 device..

I'm glad to report that after flashing the Sprint firmware on my unlocked S9+ worked no issues and knox was not tripped. Now I've noticed that even though the Sprint splashscreen didn't show up at boot, while in setup the phone did detect the exact carrier I was on (Boost Mobile) and the phone showed the Boost Mobile splashscreen upon reboot and all the Boost Mobile apps as well as some bloatware loaded onto the phone as if it were a phone I purchased through them.
So if I flash my tmobile device to the u1 firmware can I then root my device and put twrp on it?
Is any root method available for the t-mobile version?

Unlocking Samsung Note 9 N960U from USA in EU (SIM lock)

Hello everybody I have question about friends mobile. He bought it in USA from T-Mobile but now live in Europe. I think that there are 2 ways how to solve SIM lock right? First one: use some reliable but cheap service for unlocking by code. Second one: flash Android to global version? Can you tell me if it possible to flash N960U to some no SIM blocking Android? I flash some years ago some Samsung phones with ODIN, dont know if this can be used on phone sold in US.
I tried this https://forum.xda-developers.com/galaxy-note-9/how-to/n960u-tmb-stock-odin-files-firmware-t3833205 but it keep asks me for unlock network code
Thank you for any advices...

maybe try n960u1 firmware instead of the regular U. use patched odin 3.13.1b to flash it.( and flash all 4 files not just the AP.md5....)
also I belive that it might be region locked. usualy to lift that a 5 min call should have been made on US soil with proper carrier sim. if he never used it on us soil then that might have been the issue.
jd14771 said:
A N960U1 rom might work. use the CCT csc for it to be completely carrier less. thats the "Unknown" variant as opposed to XAA which is USA unlocked.

they have the same files but depending on the csc it will load different configs for each. using CCT is the unknown variant so it should ask the sim card what region its in and hopefully sim unlock it.

the firmware file you dl is all the same regardless.
now on the device if you can manualy set the proper CSC code then yes that should work as you mentioned. but if nothing is modified, then system will just pick the appropriate or last csc that was set in root/efs/imei/mps code.dat
there is an other thread in the forums that has a procedure to force csc code for non rooted devices. it involves adb and flashing combo firmware if I'm not mistaken.

Samsung Galaxy Note 9 wont install factory stock firmware (SM-N960F/DS)

Hello everyone,
I appreciate all the good stuff you are supporting here guys. thanks...:good:
Just got a nice device off Ebay. according to serial number this phone is international dual sim version which was the one i have been searching for. Board serial number also matches the one which is printed on the back of glass.
Surprisingly enough the firmware and CSC is for korean SK telecom and only supports single sim with wrong imei code compared to the ones printed on the back glass (while serial number matches and there is also second sim option on the sim tray). The imei is operational and accepts carrier signal.
Apparently the phone is altered (knox warranty void 1 (0x0400)) but what makes me nuts is the fact that the device "refuses" to install its original factory firmware (according to s/n the phone was originally made for Israeli market which is the one i am trying to install.
Unfortunately i am not allowed to paste image links to show you how exactly errors look like but long story short:
- software installed is n960N
-software i am trying to install is n960F (native software)
-phone accepts 960N combination rom but refuses to install 960F combination rom just like firmware...
-phone has this error message: secure check fail : (pit) while odin says: Re-Partition operation failed
pls review the error messages and write your comments about this strange situation. thanks.
Because it's N960N, so you need to flash N960N firmware.

The phone looks has been altered. You have an IMEI on the phone itself being different then what the phone is saying. Could just be a chassis replacement made to it. Or someone changed the IMEI which I know some do to get blacklisted phones working.
See if you can lookup the IMEIs and identify the phones by that to see what type of phone shows up. I think there is a way to do that..

Force device to update carrier settings SM-G781U

Hello, I'm not a developer; I've never dealt with a rooted device, but Google, Samsung, Verizon and other sources were no help, so I'm here now.
I got a Samsung S20 FE from my old workplace which was previously locked to the ATT network. I am a Verizon customer so I wanted to switch over and I purchased an unlock code from cellunlocker.net. I've reached out to Cellunlocke, but they say the unlock was successful as it is connecting to the VZW network.
I did a factory reset on the phone, put in the Verizon Sim card, and used the network unlock code provided. The unlock said it was successful, but the phone powered on with the ATT logo and downloaded all the ATT factory apps. When I go into the phone dialer settings, it shows ATT video calling, etc... The phone software version shows ATT in the service provider sw version. But it makes calls, texts, etc. and the network settings show it's connected to VZW. The problem is, that it can't access my voicemail or use wifi calling because it's set with the ATT apps and features.
I've tried removing the sim, power cycling, factory resetting, even calling Verizon and asking them to resync the phone to the network. When the sim card is installed in the new phone, VZW shows the S20 as my device, but the phone still thinks it is on the ATT settings. I've viewed the Service Menu *#0011# and it shows that the phone is unlocked.
The phone is showing a service provider software version of
SAOMC_SM-G781U_OYN_ATT_12_0012
ATT/ATT/ATT
Is there any way to force the phone to reset its carrier settings or service provider software? Also, please keep it somewhat simple; I'm learning but not an expert here!
about the only wise thing you can do is download and XAA U1 firmware (Samsung non carrier firmware) flash that with Odin and call it good.
you're getting what you're seeing because the phone won't be able to switch to Verizon firmware as Verizon actually have their own unique version of the FE SM-G781V I believe with physical differences for Verizon's mmwave 5G and the U model can't reset itself to that.

So which firmware version do I need? The model printed on the phone is SM-G781u. SamMobile has 781O, B, U, U1, and V for the 781 model.
I'd love to have it without the bloatware Verizon installs, but I need Wifi calling to work and it seems to be a setting in the dialer, rather than the phone.

flashing V would be a bad idea, 5G wouldn't work, at least not well. so that leaves U1 which is Samsung unbranded, no carrier apps at all.

I'm looking at the instructions for flashing the device and the instructions say to turn on OEM Unlocking in developer options. I've activated developer options and USB debugging, but do not have the option to turn on OEM Unlocking.
I can't seem to find a way to unlock the bootloader.

to the best of my knowledge you don't need to be unlocked in order to flash signed, official Samsung firmware. many Americans have cross-flashed their phones and none of them could unlock either.
you're just booting into download and opening Odin, it's not much more than that.

Awesome, a flash using ODIN seems to have worked; the phone is active and not showing any carrier apps or splash screen. I'm having some other issues; can you suggest which firmware combo would be best?
I used Sammobile.com SM-G781U1 with Country Code USA (Verizon) (VZW)
OR I also downloaded Frija SM-G781U1 with CSC of XAA
Will I notice any major differences in them, or just try each one and check it out?
I am in the US, using the Verizon network. We do not have 5g in the area but the phone and our verizon plan is 5G capable and I would like the option if it exists somewhere I travel to.
I am in the UK, I shouldn't be telling you anything about what firmware is gonna be best over there.
other than U1 XAA I can't tell you much. also be aware that generally you can never downgrade your firmware unless it has the same bootloader version as what you're currently using...
if we were looking at my firmware version number G781BXXU4FVE6
I can only flash something that has a matching 5th last character, that's a 4 in this case. I can only download and flash older firmware if it also has a 4 in the same place in the build number. the phone won't accept anything else.
Sammobile is good for seeing what firmware exists but it's terrible for download speeds. I use Frija mainly but that only gives me the latest version nothing historical.
@3mel thank you for all your help! I've got this device working well on the U1 software and didn't have to reflash it; the rest of my issues resolved. Thanks for your patience in helping this newbie do things to a phone I never would have attempted otherwise!
