CSC wont change from VZW/VZW/VZW - Samsung Galaxy S10 Questions & Answers

Hey, I bought a used unlocked S10 recently since my old phone couldn't do VoLTE. However, I am still unable to enable VoLTE, this is likely due to the fact that my carrier software is still VZW and I am running on an ATT reseller network. I have flashed my phone with two different unlocked ROMs (one from frija and one from sammobile) but my carrier services software version never changes... Is there something I'm missing? I am happy to provide any information that would help

I've run into similar issues with some phones, and it doesn't seem to be software related. In my case, I needed TFN (Tracfone) and my phone switched over properly, but my wife's would not. I ended up returning that one (Ebay purchase) and getting one that was already TFN to fix the issue. I was simply not-able to get it to change. Note that my phone was SPR, and did change... while hers was VZW and would not... so maybe that has something to do with it?
I will also note that ATT tends to be very annoying to deal with, from what I've read. They seem to be sticklers for using only phones with THEIR IMEI. I've also read here that they refuse to run VOLTE on unlocked phones, in general. So that could be another issue you're going to have. My suggestion is to dump them, as they are getting to be quite awful from what I'm seeing (and I thought VZW was bad, which is why I dumped them for TFN! Of course, VZ bought TF anyway, so they keep pulling me back to them!)

Install stock or Tmobile firmware on Samsung Galaxy S6 Edge from Verizon

I bought a Verizon Galaxy S6 Edge few months ago. Now I moved to T-Mobile. I am using the phone right now without any issues.
There is still Verizon crap on it that I cannot uninstall. Is it possible to install stock or preferably, T-Mobile firmware on this device?
I'll just keep it short and sweet. Practically speaking, no.
Better explanation please
The phones are identical except the firmware. Why would it not work? I would like to do the same so I can access better reception and wifi calling. There's literally nothing different Hardware wise between the diff carrier versions other than what each carrier unlocks or blocks. Can someone give a more detailed reason why it won't work?
This is a great question.... I'd like to know the same, BUT, for me, Tmobile charges too much for single service here in Colorado.
What about just bypass frp?
As far as I'm aware I believe the Note 5, based on the Exynos7420 uses a different modem chip in each carrier. Originally I thought the S6 Edge was still a universal World Phone. But even rooted, some people have still had problems actually migrating from Verizon to T-Mobile.
I've had a tester somehow manage to install a TMobile modem on an AT&T Note5, but it messed up the Device Root Key. Which I do believe is the "hardware baked" signature used to decrypt firmware.

Look at the instructions posted here to remove bloatware. I believe if you substitute the correct counterpart firmware the process is still doable. There is also the De-Bloater v3.90 app that should work as well.

bought used sprint SM-N950U

I bought this used today not really noticing that it was Sprint branded. I put in my Cricket SIM and it worked fine, but when I restarted it I noticed the Sprint branding didn't go away.
Phone has odd issues like the SecurityLogAgent and the Lookout app, both I can't get rid of. How can I remove the sprint stiff on here?

You should be able to find a non branded filmware on sammobile, which version you need I would not know though, being from the UK with an Exynos.
Need to look at following thread. . https://forum.xda-developers.com/galaxy-note-8/how-to/guide-sm-n950u-u1-t3685884
Thanks. I'm loosely familiar with the process of flashing. I do wonder if problem can get any better though. This phone's imei doesn't pass Sprints financial eligibility check, yet it works fine with Cricket. Would flashing be useless or problems always arise?
I did notice in the menu, that phone does indicate SIM unlock.

Multi-line settings in Unlocked s10

Does anybody know if the unlocked s10 will have access to Multi-line settings or has had experience with previous unlocked variants having access?
On T-Mobile this setting is specifically used for native "Digits" functionality without having to use an app. It's the only concern I have purchasing the unlocked variant.
I can't speak for the S10. The Note 9 however has built in Digits support in the TMobile variant, but requires downloading the app for the US unlocked variant. Chances are the S10 is also like this.

So I had Unlocked S8 on T-Mobile and I believe S9 and S10 might have the same thing. Basically unlocked version only had: WiFi Calling, Band 12 and VoLTE and there was no Milti-Line setting, unless if you get T-Mobile branded phone. What I have done to my S8, is I flashed it with T-Mo firmware and got all the features without bloatware
This time I ordered S10e unlocked and upon getting it, will inspect and see which features unlocked model will offer and if need be, will flash to T-Mobile firmware

When you say that you didn't have any TMobile bloatware when you flashed the TMobile firmware, are you referring to the general TMobile apps (like TMobile account app, VVM, etc)? or are you referring to some other 3rd party apps that TMobile puts on post-firmware. I always thought the TMobile apps would be there if flashing TMobile firmware, but I could be wrong.

3rd party apps, for example "Lookout" antivirus app wasn't there and other that T-Mobile might put there. These apps need to be disabled and can't be uninstalled. I am fine with T-Mobile account app and VVM. When flashing, just need to flash main firmware files(4 of them) and the 5th one was userdata, which has all the unneeded stuff
When you do this, don't you void something that doesn't let you use samsung pay, etc?

No, because I flashed my phone with an official Samsung firmware
Should have known so I could have purchased the unlocked version. Thanks for the info.

Not a big deal as there were times when T-Mobile for example would release monthly security patches couple of weeks earlier and possibly the Android upgrade version early too(not always though). As I understand that Samsung is obligated to release an update for carrier branded phones and then can released for their unlocked units. If you would want to flash your phone down the road, you could. It is just the process may not be as straight forward as flashing unlocked model
Ok one thing I learned today as I was setting up my s10+. The Multi-line feature is still not activated in S10+ (most likely in other s10 variant as well). I spoke with Tmobile Digits team and it was just confirm to them yesterday that S10 doesn't support multi-line yet. The only way to use DIGITS is trough the digits app. It's definitely a bummer.
I was also told that the same situation applies to the previous phones during launch (S9 or Note9) where it wasn't initially activated. It was delivered through a software upgrade afterwards. So I'm hoping this software update arrives sooner than later.
Hope this helps other member's using DIGITS.

Luckily you got to speak to someone who actually knows or at least should know. I have messaged them through the app and through Twitter and got the same basic kinda answer but no specifics and that's if they even knew what I was talking about. Hopefully it happens soon. Thanks for the update

I took multiple tries on chat and call. Luckily I got forwarded to DIGITS team and the person knows exactly the issue and is not reading off knowledge base or written instructions.
Hopefully it arrives soon as I don't want to use the DIGITS app for it.
T-Mobile DIGITS team has actually been telling customers that the native multiline feature will not be coming to the S10 or supported on other devices anymore because they destaffed that dev team. They are phasing out the feature. Absolutely horrible decision. The DIGITS app is hot trash. They have a **** load of customer pissed about it. Especially in the business segment like me. There's a scathing thread over on the T-Mobile's forums about it.
So, now T-Mobile DIGITS experts are telling people that they are waiting on an update from Samsung to make the feature possible again.
So, I don't what the **** is going on. It's ****ery.
Unless we hear something directly from Samsung, everything is now just hear say. I'm still hoping for a software update to push out the feature.
Actually, the multi-line setting was garbage. Even on my previous Note 8 and current unlocked Huawei P20 Pro, I use the DIGITS app. Luckily, with previous T-Mobile lines, got DIGITS for free. For new customers and new lines, I think it costs some monthly fees.
Thank you!

Hey, thank you so much for posting this. I tried to contact thru customer support, Twitter, calls, walk-ins.. Seems like T-Mobile employees aren't aware not only of this issue, but of the option at all..
don't mean to resurrect this old thread, but i got my S10 a few days ago and just got off the phone with the DIGITS support, after being transferred numerous times by people that didn't know what i was even talking about. the guy said that samsung told them (tmobile) a few months ago that they are removing multi-line settings from all new devices and that users need to start using the DIGITS app instead. he even said that with any further updates on the phones that currently have multi-line settings, the updates will actually remove those settings from the phones. pretty crappy if you ask me.
I'm still using a Samsung S7 with multi-line set to On, with T-Mobile. I didn't like their Digits app, much prefer the phone's native multi-line ability. However, as others above have said, T-Moble Digits support told me that Samsung was going to remove that ability. For now, it still works albeit buggy. I have to turn the phone off then on multiple times a day to keep the second line working properly. Does anyone know another Android phone that supports multi-line with T-Mobile, but correctly?

Advice for getting a v40

I want to get a v40 to replace my Redmi Note 7
I use T-Mobile but know not to get the T-Mobile v40. So I was curious if it would be better for me to get a different one and unlock it or what should I do?
Any advice would be great because I don't want to put my self in a pickle where I have a nice paperweight
No need to get a TMo version.
A cross flashed Sprint V405UA to LG v405QA will work on TMo and get all TMo bands, plus TMo VoLTE and TMo VoWi-FI and TMo HD Voice. I know because that's the model I bought, cross flashed, and use on TMo.
I see no reason why a cross flashed Verizon or ATT wouldn't be equally good. But I can't speak there from personal experience.
But there's no cross-flashing possible on a TMo version. Once TMo, always TMo.

I saw you in some other posts and I was hoping to get you to respond to this. Thank you. I'll have to keep my eye out to see if I can find a sprint one. I like my redmi note 7, but there are many features that I want that it just simply doesn't have. But are there any other weird quirks I should know? Again, thank you.
Thanks for kind words. I seem to have a bit more time on my hands now ... I wonder why ....
The only weird quirks I think are worth mentioning is that it is not easy to root and install TWRP. Several have had issues doing so. It can be done, I and others are living proof, but it's not for the fainthearted. You'll have to bounce back and forth between several threads to get it right. There's no one comprehensive guide. If you're not looking to go that route, there really are no quirks.
As for sourcing one, I picked up mine, a mint condition device, off of eBay for $145. A steal for a phone of this caliber. They seemed to have upped the price in the meantime.

Troubles with getting TWRP working don't bother me. I don't mind that. I love messing with things a little too much. Also, with that link that you sent, although the listing said you can't use third party software to unlock it, you still can. Correct? (Well the listing you sent said that it was sprint only, but not specifically unlocked. But it showed me a similar one that is $170 that says it's sprint locked)(also that because it technically isn't software that you're using to unlock the device.)
And I do wonder why you would have more free time on your hand, I could never tell why...
In many cases, these eBay vendors have no idea what they are selling or what "tethers" come with which phones. See here's the thing. If the device is paid off, it can't/shouldn't be carrier locked. You own it free and clear, and should be able to put it on any carrier with which the phone is compatible.
From reading these forums, I knew I could convert (cross-flash) a v405UA (Sprint) device over to a v405QA (US version) which would enable more bands (that I needed/wanted for my eventual migration to TMo). And if the device in that listing was somehow actually carrier locked to Sprint, I knew I could get Sprint to unlock it. I had Sprint, I knew I was going to use the v40 for a while on Sprint, so I could easily verify its carrier unlocked-ness, and could correct it if needed.
But I didn't need to. The v405ua (which was originally attached to Sprint at some time in the past by a different customer) came to me carrier unlocked. Three weeks later, I had that same device, crossflashed, rooted, with TWRP, on TMo happily making use of the extra TMo bands, VoLTE and VoWi-Fi, and HDVoice (none of which a non-crossflashed v405UA could).

Ok, so if it isn't paid off then the seller is selling a bad phone, and they should list that in the description.
I'll buy the $170 mint condition v40 because it's a good price for the phone, and I'll have something to mess with. Thank you, again. I appreciate all the help.
It'll be nice to have a nicer phone again. I loved my S8 before I broke the screen, and after I had modded it.

Question Completely lost here. Tmobile to Verizon

Afternoon all. Haven't been on these forums in some time. Started on the galaxy nexus and eventually faded away from any tinkering a few years ago. Currently using an S21 Ultra that was t-mobile locked. Got it unlocked and switched to Verizon. Trying to research everything I can to get myself on the unlocked or VZW software to make sure I've got all that I should be getting from VZW.
I've so far found samkey to change ny CSC, unlocked software and a whole bunch of other **** and I'm completely lost
Any chance I can get pointed in the right direction? Nothing seems to make sense to me for some reason.
Sorry to come off as a bit stupid, I'm just very much out of practice.
It probably work better on AT&T I think.

The phone has all the radios needed, just have to update the software/csc to make use of them.

You're kind of in no mans land. Unless you have a very good reason to change service to Verizon, Tmobile would be the best option. Samkey won't change your Primary CSC to VZW. Verizon Firmware will remain in conflict with your TMO Primary CSC. Hard to say what compatibility issues this evokes. Samsung is making it more challenging to mix and match Firmware/CSC's. If you have a Multi-CSC device normally you SHOULD be able open the dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press the Dial Icon, you should see a screen with the list of available CSC codes for your device. Select VZW and tap the Install option. Another user with similar issues stated Android 11 eliminated Multi-CSC options so if you are bent on having Verizon as your Service Provider give it a shot and see what happens.
Circumstances changed and my reception has taken a serious downgrade. Add in the awful experience getting the network unlock done. I changed to VZW already.

Honestly, I haven't flashed a phone since my galaxy s5. I'm in the exact opposite situation you're in. Was going to try flashing tmobile firmware, and saw this post. Curious if it all worked out for ya
Not hard at all. Fire up ODIN, use the XAA (Or whatever region you are) U1 firmware, flash the wipe CSC in ODIN, boot, insert VZW SIM when it asks. Done.
*Edit I flashed a Tmob to unlocked in about 5 minutes. Check the U1 firmware post for instructions. https://forum.xda-developers.com/t/...1-firmware-links.4220223/page-6#post-85580269
