Hello everyone, I'm really struggling here, I bought a Factory unlocked S21+ (SM-G996U1), I'm trying to use a Movistar SIM card and when I power on the phone it works just fine LTE and everything but after 5 minutes or so the phone show the notification that I've attached and I lose all connectivity.
I've tried a lot of things, first of all disabling the app that is running that notification (the only verizon related app on the phone) and it still appeared.
I Flashed the phone with stock factory unlocked firmware but it doesn't change, also the phone detects that I tried or did flash the firmware so I think it's not actually doing anything.
I bought credits for SamKEY and tried to change the CSC from VZW to XAA but nothing the process passed as a success but the phone shows that it's still on VZW.
I really don't know what to do, I've tried calling Verizon from my country but I can't get any help because the recording keeps asking for a Verizon number that I don't have.
If someone has any clue to what to do with a Factory Unlocked Verizon S21+ please help me!!
Thanks!
here's the notification
You will try to flash international version multiple csc rom...it helps to detect & set supported csc automatically...
I tried flashing the US Factory Unlocked firmware (CSC: XAA), but it does nothing
That phone is NOT factory unlocked. It's a Verizon variant that someone flashed the U1 firmware to - and it's still SIM locked to Verizon (that's what that Change Carrier message means).
What's the Baseband Version on the device? You can find that under Settings-->About-->Software Information

If I flash unbranded FW on a carrier specific device, loke tmo or att for example, would it sim unlock the phone?
If I flash tmo FW on an att s8 would it in turn allow me to use the att original device on tmo? I ask these questions because I feel like it would work for both my questions since flashing the FW flashes both boot, kernel and baseband/radio. The which is needed for signal. Just some theories but would love to know the answers.
Btw, I have a F model S8+ and was planning on buying some US branded devices so I was curious.

No, it will not unlock the phone (Note: Verizon phones are factory unlocked and remain that way after a firmware flash)
Yes, you can flash any carriers FW to a US S8 and use it with a different carrier.
So I understand, your saying if I flash att FW to a T-Mobile s8 I can use it on tmobile? If that is the case, to me that's an unlock of sorts tiny book lol. Just wanna make sure is all

You can flash att firmware and use it on TMobile but it will still be locked to TMobile. Just running att firmware.

Just realized the typo.....what I meant was, if I flash ATT on a TMO variant I can use ATT while locked to tmo? I'm very unfimiar with combination fw and always opted for the UK models for alot of reasons. Sorry for the confusion of my op question. I know on the s7 and edge if you flashed the US unlocked firmware it not only removed AOL bloat but it unlocked the device. So that is why I ask.

I had a TMobile S7 edge and flashing unlocked firmware never unlocked the device. That's handled by TMobile servers so...
Flashing unlocked firmware will give you just that. The smoother, bloat free firmware from another device but not the actual sim unlock.
I bought an unlocked device and wanted wifi calling so I flashed the g950usqs1aqf7 att firmware with Odin and it worked to enable wifi calling but I'm unable to get any ota updates and I hate the bloat. Is it possible to get WiFi calling with an unlocked firmware like this one? Also what is the difference between the U and U1 firmware variants?

There are plenty of threads on this, but I don't think anyone was ever successful. I flashed att Oreo to my u1 and got the options, but can't get my company to change my imei back.... My personal phone sim works fine. Quit at that point since it's an Ims registration error. You can try merging the wifi calling apks, but I'm pretty sure it's baked pretty deep in the os. The Verizon guys got some of it working. You can try their threads and see if any of it applies to us.

Thanks. Some threads made it sound possible but inconclusive. I'll just assume it doesn't work.
BTW, can you link to the att oreo fw? And what do u flash that with Odin or comsey?
The thread right below this one entitled Oreo ota has all the details and it needs to be side loaded through adb. Not Odin. But you will need to Odin the 950u base to get off u1

Ok thanks. I need to flash anyways because I'm having terrible battery issues and just debating whether to go to a newer version of 950u or back to U1 and losing WiFi calling. In your opinion is oreo beta worth it
So just to confirm, I have read everything, but I am just a bit confused. If I flashed the unlocked firmware via modified odin on a locked AT&T S8 it will remove a lot of the carrier bloat and give my my wifi hotspot back, but remove wifi calling. Similar to when I flashed the T-Mobile firmware on my AT&T S7 and got rid of a ton of the AT&T bloatware but was able to activate my wifi hotspot but lost wifi calling. I stay locked to AT&T which is fine that is not my purpose for flashing

The links don't work. Any chance you've still got the firmware? I've been overseas since october. I have an unlocked AT&T phone that I intend to keep using when I get back, so I want to keep it AT&T FW.
Hi.
I have a G955U Galaxy S8+ AT&T Factory Unlocked on Android 7.0
Baseband Version: G955USQU1AQD9
Android Security Patch Level - April 1, 2017
I no longer live in the US, and currently in the Philippines. Phone works great and the signal is too and all, but I cannot get OTA updates.
Can I just download the firmware file in this thread and flash straight through ODIN, or do I need to follow another guide?
I bought an S7 recently with an IMEI blocked by T-Mobile.
Update: I have, successfully, flashed to G930U. This was done through Odin following this thread: https://forum.xda-developers.com/tm...g930u-firmware-to-t-mobile-s7-t3533918/page1
Good news is that when I insert a different SIM card I now get access to a prompt asking for an unlock code. Maybe I can unlock it for Verizon, Sprint, etc?
Bad news is that I currently am on MintSIM which use T-Mobile networks. So it cannot be activated.
More information: I did ring up multiple times to T-Mobile and managed to get a difinitive answer that "Yes" it is still being financed, and therefore only the account holder can activate it.
I think my best option is to sell it making the bad IMEI number clear. Or to purchase a broken S7 in hopes of replacing the IMEI number physically.
Previously:
I want to switch firmware so I can unlock the IMEI without going through T-Mobile. Would it be possible to use Odin to flash Sprint firmware or Deoxed firmware?
I rooted the S7 and tried to install the Deoxed firmware through FlashFire but the S7 interrupted and restored it to default firmware. Which app files do I need to disable to stop this happening?

There is a guy that can change or unlook your IMEI, look in the forum you can find him. Change the rom or firmware does not change your IMEI.
hope it can help

I have changed the IMEI number to an old phone of mine. Which is legal AFAIK, but it still isn't letting the phone be unlocked by T-Mobile.

It was originally an unlocked model straight from Samsung. I flashed AT&T firmware so I could use some features. I figured this build number would receive OTA updates.
i never got ota updates on my unlocked phone. I've installed 100% at&t stock firmware.

Do you have ATT Rom on it or it the stock Rom from Samsung?
Also, can I ask what you told them to change the IMEI?
I called and they were telling me I can't change the IMEI and that even if we do change it, it would only work on the previous phone... which seems bogus...

Was originally unlocked direct from Samsung, I flashed AT&T software.
I just flashed the update on my own, I don't know if I'll ever get OTA.
I had no problem changing IMEI. It had my old S7 edge IMEI, I used chat to change it to my current Note 8. Then quickly had them switch it to Note 7 IMEI once WIFI calling wouldn't work. They asked no questions both times. Just told them I upgraded phones and need to update my IMEI. I've never called them, just used the chat feature.

Did you need to give them the old SIM#?
I have info in my email before returning my Note 7 but nothing on the SIM card # and wonder if that might give me some trouble later on for wifi calling.

You need active AT&T sim cards or AT&T MVNO (Red pockets(310 410 but not Freedompop 310 170) sim card in your phone to get AT&T software update.

Flashed it including home CSC. Wanted everything so I could use wifi calling since that was the whole point in the first place.
I usually buy unlocked notes, but this time ended up with t-mobile note20 ultra 5g.
Can i able to convert to at&t, by just flashing home_csc or need to flash a full at&t firmware? (if it is even allowed!)

It is tmo locked, requested unlocking via twitter few days ago, still waiting.
Current firmware is N986USQU1BTJ4, but it is trying to push for a new update (by tomorrow morning). Dont want to get this too high and stuck.
i flashed N986USQU1DUB5 from "OTA and Non-OTA Firmware for N986U and N986U1" thread and used CSC file (instead of home csc) as my phone is blank. It did not do the factory reset/still showing tmobile only !
tried *#272*imei# to see if i can check the csc manually, but nothing happens ! - may be what @mindseye0803 already said as oneui3.1 !, will check by downgrade and see !
re flashed N986USQU1DUB5 with csc/userdata, it solved my issue, can see and enable wifi calling from at&t.

Hi all,
I bought this phone from my friend who was using it on ATT. It is global unlocked phone and I activate and register, change new 5gsim and no problem on Verizon Network.
It is working and fine but, it shows ATT logo when phone is boot up and still it has ATT bloatware.
Under the Software information > Service provider software version is showing below
SAOMC_SM-F711U_OYN_ATT_RR_0016
ATT/ATT/ATT
SO THIS PHONE IS legit!! even Verizon told us. They did everything with me for 3 hours. wow!
Anyway, I think it's the problem of other carrier's software is in
Do you guys know how to change provider software to Verizon? should I contact Samsung??
Please help me.

@iHeartslutsz https://www.sammobile.com/samsung/galaxy-z-flip-3/firmware/#SM-F711U1
Whenever I flash a new software through Odin after downloading it from Sammobile, the Dark Side RC theme (I think it's related somehow to the so called Star Wars special edition) for samsung, comes as one of two default themes into the system and can not be removed. Hence, even I change the theme from setting, this iron head appears everytime I restart the phone for a few seconds. So I tried different firmwares for my country but nothing changes. So someone from another forum said that my service provider software version differs than theirs. So in short, how to get rid of this silly iron head? Any help would be appreciated.
change csc, use SamKEY (paid) or SamFwFRPTool (free), then flash frimware you need with odin with CSC file (this will wipe your phone and reset to factory), not use home_csc in odin

Thank you. I downloaded totally different firmware files with different CSC code and the problem has solved.
SamFwFRPTool is a tool I use to change my CSC software channel. The way I understand it you need to change the CSC in the program before flashing the u1 software on it so you get a full unlock as opposed to a partial one.
I might be wrong here though so don't take everything I say as being true.
