Question Phone status custom despite downloading official firmware with smart switch - Samsung Galaxy S21 Ultra

Hello, as the title says the phone status on my phone says "custom" despite updating the phone with samsung smart switch, knox isn't tripped aswell so I don't really know what the problem is... Any ideas?
Just found out that the CSC code on the phone is G998BOXM6EWB4? This is wrong right? Its supposed to be NEE for example? Phone info cant seem to find the "original CSC Code" or "Firmwares CSC Code" but the active CSC seems to be NEE

You have to use Odin to flash your device. Smart Switch won't do it.
Bootloader is locked?

Flashed XEU with Odin now it's asking for a Sim unlock code?

I have a sm-n690f/ds and I flashed the XEU in Odin because I had a binary error after flashing the T-Mobile detonator
Phone works and sees my sim but it's asking for an unlock code it never needed when I had it on tekhd
Anyone got any help? Do I need to buy a sim unlock code even though I never needed one before?
My CSC says XEU So I'm confused
Also I rooted the phone again after the newest XEU Odin flash and can successfully boot into a ROM but am still get the sim unlock prompt
OK I found out it's a Malaysian phone originally so I'm flashing the Xme firmware through Odin. Let's see if this helps.

SM-N950U Software Update Problem

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.

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...
Thank you a lot

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 .....
Thank you

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

Thanks.
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?

Simple csc change?

I purchased a usa gsm note 10+ unlocked. Since was going to use it on tmobile I set csc to tmb. Id rather get my updates via Samsung so v would like to change the csc to XAA so I get the samsung releases instead of tmobile branded. I tried searching for answer but couldn't find the post I followed before.
All I recall was I use a field code to get to the set csc. I dont think it was the imei one and if try to run
*#1234# I get the following
Running USSD code
then

Question Flash Verizon Tab S8+ to different region?

Hi fam,
Recently purchased a Tab S8+ 5G from Verizon. I love the device, but I absolutely HATE Verizon's Message+ app. I would love to be able to use Samsung's Calls and Texts on Other Devices feature with it, but Verizon blocks it in favor of their homegrown monstrosity.
So my question to you guys is: is there any way that I'd be able to flash a different firmware on it? One that gets rid of the VZW bloatware and reactivates the useful Samsung features? TIA
Hey, I'm not sure how it works, but my understanding is that some carriers in US(like verzion) block the ability to unlock bootloader, and add their bloatware to the device.
If you're able to do the first step of the root guide (unlock bootloader) then you should be able to flash another firmware or just remove the bloatware with root.
Some people probably have better knowledge on this than me.
Keep in mind unlocking bootloader would affect KNOX and trigger KNOX so it becomes permanent unavailable and re-locking bootloader won't bring KNOX back. Which means apps that needs KNOX won't function anymore.
You may be able to re-flash your device with odin to new region firmware. So then you don't have to touch bootloader unlock. Since I'm quite sure I have seen users here being able to flash another region firmware to their devices with odin so their bootloader is un-touched.

Normally re-flashing stock firmware won't need you to unlock the bootloader.
So when selecting firmware online to download it gives me the option for the following CSCs for my model (SM-X808U):
VZW
TMB
TMK
USC
While I get that they are all carrier specific and will come with their own bloatware, which is the lesser of the evils? Which will allow me to activate the "Calls and Texts on Other Devices" feature?
TIA

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!
