Flashing unlocked Samsung S10+ to T-Mobile Firmware - Samsung Galaxy S10+ Questions & Answers

Hey guys, first time on this forum and I am trying to figure things out. I never flashed a firmware so im a noob to this, but I can definitely follow along. Here is my main concern:
Seems like you need a T-Mobile device to get access to features like advanced messaging, visual voicemail, wifi calling, etc. Things I use all the time, but I never knew it would be taken away if I purchased an unlocked S10 plus.
My main goal is to get these features back, which from what I understand requires flashing the firmware? If there is any other way I am more than open to listen to it!
I have Odin and downloaded the "userdata" linked into this post: https://forum.xda-developers.com/galaxy-s10/how-to/g975u-g975u1-firmware-links-t3905897 specifically USERDATA_TMB_G975USQU1ASAT_CL15296297_QB21819666_REV00_user_low_ship_MULTI_CERT.zip
I figure I unzip to get the tar file, select Odin use data and only flash this file? Kinda clueless about all this.
In addition, if I were to flash I hope that Samsung Pay, Knox, finance apps will still work; also the warranty is still good. I know that rooting the device will/may make these unusable, but I just want to confirm.
Any guidance is greatly appreciated, thanks!

WiFi Calling, VoLTE are working just fine, but I get what you mean... I mostly flashed 4 firmware files: BL, AP, CL and CSC and couple of times did flash USERDATA too. As userdata file was not required to be flashed unless you want all bloatware from the carrier. Don't know if S10 needs this "userdata" file. You would want to flash I mentioned and specifically flash CSC file and not the HOME CSC(as it usually retains user data on your phone) and in your case you want odin to wipe the device. I want to flash too, but waiting for firmware to become available on sammobile website

Basically I should wait for Sammobile to upload those 4 firmware files (BL,AP,CL,CSC) and then use Odin to flash the firmware. Seems the instructions for that are really easy.
As far as the Samsung pay / finance apps, would it mess those up like rooting the device?

There should be no issue with Samsung Pay and other apps, as you would be flashing official Samsung firmware. Wait for firmware files to be available and then you would be able to see which files will be included and go from there. On my unlocked S8, I didn't flash userdata file and still had all T-Mobile features you were mentioning. If with S10 we will have the same, then skipping userdata is better as the device is pretty much clean without unneeded apps

I installed T-Mobile's Visual Voicemail app from Play Store, and it works just fine. (Unlocked S10)

I did the same. Figured if I was paying outright might as well get an unlocked device. But the Samsung's from tmobile have the multi line function and I'm trying to get rid of my iPhone. But I use that number alot as well. So that multi line function built in for DIGITS worked for me. If you flash it let me know if it has it built in

Wait. How did you get the multi line functioning on the s10? I have been scouring the internet for a solution

Curious, are there any features/capabilities that the unlocked version has, but the TMobile version does not? I ordered an unlocked S10+ (haven't received it yet) and TMobile is my carrier.
From what I've read so far, built-in caller ID, and the ability to turn mobile data off, are not on the TMobile variant, but I can't confirm that.

I don't. I have the unlocked version. But I have tmobile. Didn't think about it until I received my device. So If flashing the tmobile software will give it to me i will flash it.

Thanks for the info too! I am also quite curious about this as I have an unlocked S10+ still pre-ordered. Unfortunately, it's too late for me to cancel it and re-ordering it on T-Mobile before April comes around as I would like to use the phone on my travels by then (still hanging on to my S5 at the moment... lol).
From what I've read, the two major features lost on unlocked phones are EVS and RCS messaging. While RCS messaging is something I can live without, I would really like to keep the EVS (Enhanced Voice Service) feature usable on the phone when it arrives.
One other question, are you able to get the updates via T-Mobile on the flashed firmware or does it have to be flashed again for future updates?

What is EVS? Is that just another term for VoLTE?

VoLTE and EVS are different. EVS is an evolution of the AMR-WB speech codec (aka HD Voice) whereas VoLTE uses said speech codecs to work. VoLTE is currently recommended to use at least AMR-WB for good voice quality. As EVS is the newer speech codec that uses similar concepts to that of AMR-WB, it is backwards compatible with technologies already using AMR-WB, which includes VoLTE.
That is what I can gather, feel free to correct me if I am wrong in any of the details.

Thanks to all for their insight. Just an update:
I flashed the T-Mo firmware on my unlocked S10+. It worked - RCS and video calling are back! However I noticed 3 things: 1st I used the CSC, but it did not delete all my apps. 2nd when the device rebooted after flashing it went into recovery mode (is this normal?), but i re-rebooted it and it went right into my phone.
3rd while RCS is working on the phone and between my Android 8.0 Note8 Tmo phone, the Note8 cannot send pictures/files to my S10+. The S10+ can send anything to me, but not the other way around. Read, Delivered, typing indicators work. I am not too concerned about this as I am getting an S10+ myself next week so this will not be an issue.
Any thoughts about that?
Other than the RCS thing, the S10+ device is working completely normally. I heard you have to change the CSC on the device but I did not do that (echo, adb, and all that jazz) - is that necessary as well?
Lots of random thoughts over here!

Would you be able to help walk me through the process to do this. I used to root and flash custom roms to phones but the carrier specific and Samsung stuff is new to me. I'm interested in getting on the TMO firmware possibly for RCS but I don't know if it's worth the hassle for it yet

Thanks for that update.
By any chance, could you let us know if the built in VVM is working? (accessed from the dialer by tapping the 3-dot menu button ((from within Dialer)). You should see Visual Voicemail as an option, not just Voicemail.
I flashed the TMo firmware as well, but used Home_CSC. That didn't seem to matter, since Userdata wipes the phone anyways, but I'm curious as to whether that is why I am not seeing Visual Voicemail.
As for the booting into recovery, did you have the reboot option checked in Odin when you started the flash? Mine has booted to recovery before, but it has always been because I forgot to check that box.

So I have another update about this. When I included the userdata in Odin it reset my device. The visual voicemail is not working still, and i can't confirm (or i dont know how to confirm) if wifi calling or VoLTE is working as there isn't any real indication on the device. But all my RCS problems have been fixed!
...Except that all my MMS contains the "Subject: No Subject" header on every single MMS. Every. Single. One. I had to change my default messages app because this was just too damn annoying.
and yeah, i did check the box.

Is there a voicemail icon in the dialer after flashing? Or it's still not there?

WiFi calling option is within the phone app settings itself, and it would word even without flashing tmo

Anyone know if flashing tmobiles firmware onto the unlocked s10 will void warranty? if so id rather just get the locked tmobile version.

No. This does not trip knox, nor will it void your warranty. Tampering such as flashing unofficial software will incr the Knox counter. This matters because technicians inspect the software state (among other things during checkups).
Assuming they actually verify it, the device will fail this step (not the case when using signed packages from Samsung for conversion!). .

I spoke with a Samsung care rep on their website, who told me it will void the warranty. But then again, most customer care reps dont actually know what their talking about beyond the basic questions...

[UK] Unlocked S7 Edge - Enable EE features?

Hi folks,
So as in iPhone user, i've been following the latest Galaxy very closely and decided to take the plunge on Sunday!
Suffice to say, sat in front of me at the moment is my first Samsung (I went for the Edge).
I'm on EE, so i'd like to know how I go about enabling Wi-Fi calling (and VoLTE when it launches - although i'm aware it's testing in several areas at the moment) on my device. I bought it unlocked, direct from Samsung - which probably explains why I can't see the settings for it?
I've ready that I may have to flash the firmware with the EE version to get the features - my concern with that though is tripping Knox, as i'd like to use Samsung Pay when it launches.
Is there a method of enabling the features without flashing the firmware?
Any help on this would be greatly appreciated!

i wouldnt if i were you. i tried that with apple pay in australia and it didnt work. its region locked. wait for the official launch.
for me, my ban offers nfc payments through the phone so i can wait abit for samsung pay to arrive in australia and if im lucky, they will give out free stuff like in america.
i never tried volte calling. but you can always use whats app and stuff.
Its safe to do so,
I bought my S7 Edge from the Samsung store, and flashed the EE firmware, it doesn't trip knox, only custom changes will trip knox, So rooting/custom recoveries and such. its safe to flash the EE firmware. and WI-FI calling working for me, (How to enable WiFI calling). as we speak. But I did do a factory reset(delete everything) after flashing to make sure the CSC for EE was installing correctly.

Ah - just what I wanted to hear
Can you tell me if the EE firmware comes with loads of bloat? Also, will OTA updates work, or will I have to manually flash them when released (I'm sure I read that auto-updates don't work if flashing a different firmware - although I could have misconstrued that).
Thanks

Auto-update will work, but you will have to wait for EE to push the updates out. so might be a delay until they release them, Only difference from buying the phone from EE or Samsung is the firmware, So if you flash the whole phone and factory reset in recovery, its pretty much a EE phone. be warned sometimes WiFi calling will not work until you call up EE and ask them to activate it on your handset, (and that can be a funny conversation, since you didn't buy the phone from them but I managed to talk my way around it on my S6 edge+), And on my S7 Edge it seems to already be enabled after I flashed the EE firmware and enabled in the phone settings.
It's a shame that we still have to install carrier specific firmware to access these things. I thought I heard samsung had overcome this?
Some articles suggested that the S7 could install carrier specific software upon detection of SIM accordingly. This doesn't appear to be the case. I have just had to flash H3G firmware. BTW op it didn't trip KNOX

It is a bit rubbish really - it's one good thing Apple has over android imho. I know Google are trying to go down the same route with Carrier Updates - but they're gonna have to grow a pair if they're going to get anywhere with it.
Anyway, thanks kossiewossie - just finished flashing mine. Hoping I haven't tripped Knox (not checked yet, it's restoring my Google Account backup).
To flash the firmware is it just a case of downloading the EE firmware from sammobile and using Odin to flash it? Because I know for the S6 there was an issue where the partitions were different between the EE version and the unlocked version meaning you had to get hold of a PIT file to flash the EE firmware. Is that still the case?
I'm also considering doing the same. I'm on EE but it came through a re-seller so I've got stock Samsung firmware.
Other than the delay in updates being released, is there any other reason why not to do this? Are you able to flash back the BTU version if you grow tired of waiting for carrier updates and don't end up making the use of wifi calling?

The only benefit I see with the EE firmware is Wifi calling, but as I am in a fantastic reception area, I do not need it. Therefore I see no other reason to use the EE firmware and prefer updates as soon as they are released.
Yes, if you grow tired of waiting for carrier updates, you can flash back to BTE/XEU firmware.
I can't speak for EVR firmware. I used Samfirm to download 4 file H3G firmware and I was not asked for a PIT file.
Interesting there are PIT files included in the files if you unpack them so maybe this was used?
Having downloaded the EE firmware I'm a little confused with Odin.
I have:
AP...
BL...
CP...
CSC_EVR...
Home_CSC_EVR...
Do I need to select all of these within Odin? If so, which CSC as there seems to be two? Sorry if this is a stupid question....

When I did it last night, within Odin I selected files for AP, BL, CP and for CSC - CSC_EVR. I didn't use the Home_CSC_EVR file.
Knowing my luck, i've probably done it wrong - although my phone does seem to be running fine!!
I'm too cautious about flashing the wrong one lol. I'll wait until we know the difference I think!
Edit: Flashed it with the standard CSC. All seems well.
I flashed the standard csc myself and all seems well for over a day now. Would still like to know what the home csc file is for.
Edit. Just found out that home_csc doesn't contain the pit file so it doesn't wipe the phone. So would have to use the standard CSC when changing firmware.

Stock firmware

Hi everyone. I am attempting to download the stock firmware for my Edge but can't find it. My phone has SM-G935A printed on the back. It is AT&T. The search feature on SAMMOBILE does not have that model. Is it ok to use a different firmware? It won't be AT&T anymore if I do, right?
The back of my phone gets really hot at times, especially right while booting. I wanted to try to root and put one of the custom ROMS on there but I am not doing anything till I find the correct Stock Firmware.

I'm running my AT&T S7 Edge on this firmware, WWWWAAAAAAYYYYYY better than stock AT&T. It has NO AT&T bloatware and it has the Mobile Data On/Off toggle listed in the quick toggles bar. Before you flash this on your phone check what build you're on in the "about phone" in settings. Here is the link with the latest stock AT&T Firmware, https://forum.xda-developers.com/att-s7-edge/how-to/firmware-pi2-s7-edge-sm-g935a-10-03-16-t3477246. Download to your pc in case you want to flash back to stock. Don't root, not really stable if you do and you can't install any other firmware / ROM unless you flash 935U Firmware. You can brick your phone or even trip Knox counter and that will void your warranty if you needed to return to AT&T or Samsung.

Hi and thanks. I don't care about warranty. I am thankful you explained that "ROOT" makes it unstable. How is it possible to flash custom ROMS without ROOT? Why is it so hard to find the dang firmware? I went back on that dang Sammobil to look for the stock firmware for a friends Verizon S7 Edge and I can't find THAT but NOW THE AT&T is there!!!!
It sounds to me like you are coming from an older phone that had an unlocked bootloader? Back in the day when flashing a new rom like paranoid or slimrom was the fun and cool way to differentiate your device from your friends. That was also a time when android was about as locked down as ios is now, and ios was still locking users into their own keyboard, and Samsung was scrapping with apple at every turn for the top seat in the mobile phone market. My how things have changed.
Android is much more open in some ways, there are far fewer things that most people need that require root access, and the device manufacturers have also begun locking down the devices much more. At least in the Samsung line, I don't know when the last US variant flagship bootloader was freely unlocked? The s3? I know I had a Verizon s6 that I could not even achieve root on following a certain point in the release cycle. Now we have all of these fun new terms like systemless root, magisk and engineering bootloader. It really comes down with what is your desired outcome from rooting. You can actually get a long way towards what you could do back then with a Samsung theme and the right apps.
I believe what ytaida is referring to is the ability to flash other s7 roms onto your phone. So while we may not be able to flash custom roms, anything with the correct bootloader can still be flashed. Typically with a phone that is only going to be in the same model, but Samsung kind of threw a curveball and created an incestual path for the s7. With their U firmware, (the 930U and 935U firmware shipped on the devices sold directly from Samsung as was mentioned above) you could flash an official version of that onto the tmobile, Verizon, att and a few other carriers hardware, and essentially change the model of the phone. From there changing it back was equally as easy, except changing it back could be changing a Verizon model into an att model. The radios were all the same. In this process a root exploit was achieved and some very smart (I am humbled by their knowledge and determination on these sites every day) folks started hacking together roms. So you will see some neat stuff done where you are never truly running as root, but there were modifications done as root somewhere along the line. Long story only mildly shorter. Be careful how far down the rabbithole you take this.
The next thing you know it could be 6am and you realize you've been downloading and archiving your own copies of stock Samsung firmware for the last 20 hours, for devices you don't even have lol..
Sure there are still custom roms out there, but as a US customer, if that is what you're looking for you are best off with a nexus device or One Plus.

Is not hard, just need to look in correct forum. BTW what firmware you want. You can find any firmware you want for both models. Just look harder.
On Edge of Galaxy
A few things:
1) There doesn't appear to be any physical difference between the 935A, 935T, and 935U. You can, as long as you mind the bootloader version, freely switch between the three versions. I'm not sure about the Verizon and Spring versions.
2) The 935A FW link is around here. I've used it, and it worked fine, but you will be on tap for a few OTA updates.
3) The 935T FW link is actually available in several places, but there is a direct link over in the T-Mobile S7E forum. I'm not really sure what it gets you that the 935U doesn't, though. It has less bloat than AT&T, about the same amount of branding, and AT&T still refuses to let you have access to the more advanced call features. It does appear to be a lot less laggy than the 935A, though - AT&T really screwed up the Nougat upgrade compared to everyone else. It will likely get updates faster as well, and T-mobile doesn't have provisioning checks for tethering.
4) The 935U FW link is also "stock" for this phone, and works much better in many respects (it's certainly faster and less laggy) The difference between the 935A/935T and 935U firmware is that the former two have all the software needed for AT&T/T-mobile specific features, like WiFi calling, VoLTE, Visual Voicemail, etc. The latter has none of those things, but it does give you back BT tethering, disables the checks for WiFi and USB tethering, along with a few other features that were disabled.
Thus, you need to decide what is more important. Carrier specific calling features or more tethering options and overall better performance and battery life.
Please check the ORIGINAL post date!!!
I got the help I needed MONTHS ago. For those of you actually attempting to help,
"THANKS".
NORBARB, as a "SENIOR MEMBER" I would have expected much more than that and again, please look at the date I posted that question. Of course the firmware has shown up now. I don't even own that phone anymore.
How do you determine bootloader version?
jshamlet said:
A few things:
1) There doesn't appear to be any physical difference between the 935A, 935T, and 935U. You can, as long as you mind the bootloader version, freely switch between the three versions. I'm not sure about the Verizon and Spring versions.
2) The 935A FW link is around here. I've used it, and it worked fine, but you will be on tap for a few OTA updates.
3) The 935T FW link is actually available in several places, but there is a direct link over in the T-Mobile S7E forum. I'm not really sure what it gets you that the 935U doesn't, though. It has less bloat than AT&T, about the same amount of branding, and AT&T still refuses to let you have access to the more advanced call features. It does appear to be a lot less laggy than the 935A, though - AT&T really screwed up the Nougat upgrade compared to everyone else. It will likely get updates faster as well, and T-mobile doesn't have provisioning checks for tethering.

I'm interested in switching my unlocked Tmobile G935T to ATT G935A to take advantage of Wi-fi Calling. I'm not sure how to make sure I select the AT&T firmware that has the same bootloader as mentioned above.

S7edge SM-G9350-NO 4G DATA**I WILL DONATE $50-$100 TO WHOEVER GIVES ME THE SOLUTION**

The exact model is Samsung Galaxy S7 edge SM-G9350 64 GB GOLD PLATINUM
First I want to get this off my chest. I registered this week (I used XDA before like 7 or 8 years ago in high school when I use to flash custom ROMS on windows mobile phones-good times hehe)because I am frustrated since I bought an unlocked Samsung Galaxy S7 edge from a stranger using craigslist on Sunday night. The ad said it was T-mobile Unlocked and in brand new condition with the box and original accessories and it had some pictures.So why not buy it cheap for since I'm using a T-mobile LG-K7 with a cracked screen,right?WRONG!! The phone is working fine except I am only getting EDGE data!!! I found out that it is a chinese variant and it works fine with my T-mobile sim card here in the U.S.A except it can't connect to 4G and that is probably why the shady guy sold the phone cheap to let it become someone else problem I also saw 1 or 2 of these models in the box as well and he said a friend gave it to him and he is just selling it(B.S.) I forgot craigslist had scammer like 40% of the transactions lol, I use to meet these types of people in middle and high school when I bought and sold my used or old T-mobile phones though I never scammed or conned any one.I remember some people would act shady or too nice for no reason,probably cause they stole the phone and were making 100% profit off me.This same guy is one of them.
ANYWAYS THANK YOU FOR READING MY RANT---- NOW ON TO THE POINT OF FIXING THE DATA ISSUE
I am getting unlimited 4G on my k7 and everyone else on our plan is using unlimited 4g just fine.Samsung rep at best buy said its legit and its an international chinese variant and to look around on here to fix the issue. He told me something about the band and t-mobile towers to pick up the frequency. He said I got a really good deal if I can 4g on there. If not than re-sell it and make it someone elses problem. I looked all around google the past few days an either no one has this problem or if they do than the solution doesn't work on my phone.
Here is what I tried so far:
A) T-mobile reset the network connection via tech support
B) I factory reset the phone numerous times
C)I got the right APN settings set on the phone to be connected to nearest towers, a store rep did it for me to make sure.
D) I replaced and used another activated T-mobile sim card
E) I download some apps I saw on here to check LTE signal etc and its running very slow edge
*********I am on the sim status screen and right now as I'm typing this the signal strength is
-61 dBm 26 asu,cellular network type is EDGE,NETWORK is T-mobile, Service state is In service,Roaming is not roaming,cellular network state is disconnected*******
------I hope someone can pick up information off of that and maybe I could change some settings
E) I dialed *#*#4636#*#* and got to a screen to allow me to check phone information,battery information,usage statistics,wi-fi information-under phone information there are options to set preferred network types to: WCGMA,GSM, GSM auto(PRL), CDMA auto(PRL),CDMA only,EvDo only,GSM/CDMA auto(PRL),LTE/CDMA auto(PRL),LTE/GSM(PRL),CDMA auto(PRL),LTE only,Unknown. It will only stay on up to GSM auto(PRL)
....also when I press menu on this screen there is an option to enable data connection and when I click it,it won't stay,it just keeps saying enable data connection
F)I googled what bands this model and it is able to use and it has the capability to be used on T-mobile bands
What else can I do get the data working to 4G right now? The phone is running Android 6.0.1 and won't update to Nouget over the air. I want to root the phone and see if I can install a custom Nouget rom( since the samsung guy said the phone will brick if I try to install the T-mobile Nouget rom or I can't even do it since its an international variant-by the way I am able to have google services on here like play store,etc. so I don't know if that makes a difference to what variant and rom it is because I heard one or the other of hong kong or open china variants for this phone is better and can't use google play)and maybe I am able to connect to 4G data.
Like the title of this post says, I promise I will back up my donation I really don't want to sell the phone unless I have to because I will not get a better deal anywhere ever again for the latest high end phone from a manufacturer

you have to flash the correct CSC this will fix your 4G if you buy an device from a other country than is it possible that you get this problem but when you flash the correct CSC you will get 4G i helped so much people with this problem with a S7 device, i think this your solution
if this fix works for you just keep your money we are developers not for paying
Maybe you should post this in the T-Mobile section.
In my idea this should have 4G data on T-Mobile US out of the box as the required LTE bands are supported by the G9350. Did you check the APN settings? (VoLTE and WiFi-Calling may or will not work without t-mo-rom but that's another topic)
Also you should be fine to flash a T-Mobile US rom as both have Snapdragon SoC. You don't need root to flash an official rom.
Out of curiosity: what about 3G?

Thank you so much!!! People have actually asked through pm to donate to bitcoin first before helping me and here you are helping me first by the way.
I am going to find the correct CSC, what does that stand for? Can I flash a T-mobile 7.0 Nougat rom on my Galaxy SM-9350 first that the person before you replied about(its the link)?? I want to do both to have T-mobile settings and to use the 4G although the 4G is a thousand times more important. If I can do this than I am a happy man!
Why is there a boot loader and modem link attached to every post containing a ROM download? Does that need to be downloaded first,and what are the next steps,if so? I know these are questions I need to search about they are all confusing and mumbled and jumbled up. Even though I registered this week for help I was a member here like 8-9 years ago in high school when I was flashing custom ROMS on Windows mobile phones(good times hehe) but it got addictive,took a lot of my time from studying, and I totally forgot how do things.

Hey I made a new thread today in Q&A for GS7. The APN settings were put in by a T-mobile store associate and it still didn't work. I don't care about VoLTE/Wifi-Calling although I noticed some people on here are worred about that-its just something I never use.
Are you sure I don't need root to flash an official ROM?The Samsung Galaxy guy at Best Buy said it would brick if I used an official ROM because the phone is an international variant. If I can use an official ROM,I can't get Nougut OTA via T-mobile anyway as my phone keeps saying it is updated even though it is 6.0.1. How do I get the offical ROM manually on the computer? Samsung Smart Switch isn't even recognizing my device when it is connected and Smart Switch on my phone looks like it is only suppose to be used to receive files from another phone? I have the link for a T-mobile 7.0 ROM from a post on here that he used on the same exact model I don't know if I am suppose to root the device first or not yet since it looks custom made.
Thank You for helping me out it means a lot you guys are the best! I can already see myself on here a lot in the future doing stuff different android phones like I 8 or 9 years ago in high school on windows mobile phones.

The only data I am getting is EDGE
So, I guess something is wrong.
You can try flashing the designated firmware for this device first and see if this helps. To get the right one (who knows what all was tampered with) use best the Phone Info tool.
I've had this exact issue before, with a Nexus 5 that I bought from Telus, I am with Telus, it ended up being I had to go buy and register a new SIM card, then it was fine, might not be a solution for you but Worth a try,
Actually get a SIM card from your provider, have them register it in the store

Nice, I like what you have! My model is different so I don't know if the ROM will work though I'm almost finished downloading it at the moment. Instructions 3 and 4 is confusing. Don't I need to put superman ROM and CSC file on sd card while the phone is ON?And am I suppose to transfer it on there via usb cable or can I also do it via google drive than open in up phone gmail and put it on sd card? Also do I need to extract the CSC file first to my computer desktop? That file takes forever to extract! Is instruction 4 suppose to be while in recovery mode? Also is it normal for my phone to show "no command" while in recovery mode?
Thank you ?
The rom will work because your phone is exynos based. It got a different model number because it's for Chinese markets. Put the rom on the SD card using whatever method, just do it before flashing the recovery, because your phone may not boot after the recovery to the stock firmware because Samsung has put some crap to prevent using custom firmware. I forgot to say that also before doing anything go to device info - > software - > and press build number several times to enable developer options then back to settings and go to developer options and enable OEM unlocking.
Yes, commands 4 are made in recovery. Install - > pick the zip file and install.
All zip files aren't extracted! The recovery uses the zip file as it is.
Good luck

Were you able to flash the U.S. T-mobile ROM onto SM-9350?
The official firmware can be found on https://www.sammobile.com/firmwares/database/SM-G935T/
I found it yesterday but their free server is under maintenance so he will have to pay to just download a firmware file.
I don't know why don't samsung provide them for free on their site!

Have a SM-G930V. Want to flash but have no idea what to do.

Hey there, hope y'all are doing well.
I recently purchased a Samsung Galaxy S7 SM-G930V, Nougat 7.0 (note: I live in europe, and it's an unlocked phone). I want to get rid of Verizon logo while booting and all the unnecessary apps connected with Verizon. Plus, as you know Verizon locks some functions like the device maintenance, turning off the backlight of the capacitive buttons, etc, etc.
So, I'd like to have a clean/untouched samsung firmware without any useless apps.
Is androidfilehost.com trustworthy? what about updato.com? (the latter had slow dl speed, and I stumbled upon the first alternative)
PS. by the way, mine reads G930VVRS4BQI1, so one thing that confused me was while loking up for files to download; should I get the G930VVRS4BQI1 which may be the only compatible file for my phone, or do I already have G930VVRS4BQI1, so downloading it would be useless?
Since I wouldn't like to tinker often with the phone system, what do you suggest, flashing or rooting?
Is there any guide for my case for flashing?
I noticed these two on the front page:

which should I pick?
and since the posts were last edited in may and september, where can I find the latest firmware?
and after doing all this, will everything work well, will I get OTA updates?
I would really appreciate someone helping me out, whenever you're free.
Thanks in advance
You can actually cross flash any Qualcomm s7 firmware between all carrier handsets. With your case being in Europe I would recommend the sm-G930U firmware. Which is the carrier unlocked variant of the S7 stateside that has all bands unlocked that the modem is capable of. You will recieve OTA's. It's Odin files are on Updato and SamMobile. AndroidHost is trustworthy.
In your case of not wanting to tinker or have a "need to have" rooted feature on the new device, I would flash the the 930U firmware and enjoy your new non branded system.

Hey JediDru,
I also just bought the S7 Verizon variant, and am planning on using it on MetroPCS. Would you recommend the 930U firmware for me as well? I wouldn't mind getting rid of the Verizon bloat before I hand it over to my wife...

You very well could. I think there is a thread around here specifically about metropcs setup somewhere between the verizon s7 and tmobile s7 forums. I use my 930v flashed to 930U on tmobile.

hey there, thanks for your advice! I downloaded the latest file from here. sammobile"dot"com/firmwares/galaxy-s7/SM-G930U/VZW/
In a moment I was clueless at the "pick country" since there were more than one USA options. so I went with verizon, since my phone comes from verizon.
In the link I mentioned above it reads this This is for SM-G930U from USA (Verizon) which makes no sense to me, how it can be both "U"-unlocked and verizon at the same time... but, oh well, I flashed it 4 days ago and I've encountered no problem, which is all that matters! Hope I made no mistake at picking that file.
Recently purchased galaxy S7 SMG-930V (Best buy version) from a private owner.
I am on cricket and on APN setup LTE and MMS works without issues. Only issue is that upon dialing USSD code i get 'Connection problem or Invalid MMI code' . I tried all options available mentioned in this forum still doesn't work. Which version of SM-G930U should i flash? Main reason i purchased the phone is for Samusing Pay. Don't want to brick or lose Samusing Pay option after flash.
Inputs are appreciated.

Yes Flashing the G930U firmware removes all carrier bloat.
Samsung pay comes with the U firmware.
The last time I was on the U I had bad standby drain. I read somewhere else it has to do with the U not dozing correctly. They may very well have fixed it now, I'm on the latest tmobile 4BRA firmware and it sleeps like a baby right now.

Flashed the verizon U firmware and it did remove all the bloatware. Still need to check on battery drain with Samsung Pay. All other apps are in "Always Sleeping Apps" for better battery performance.
For future reference make sure before flashing new firmware google accounts and lock screen securities are removed/disabled.
Is there a way to back up apps with user data and home screen and reuse instead of installing all over again when a new firmaware is flashed. Spoiled by the root and titanium full back. That was so easy.

As far as I know, no. It's not so bad. I had gotten into the habit of taking screen shots of my app drawer and redownloading. To think now I can just redownload the configuration of apps I had before is as good as it gets. I still just redownload. I like to re-set everything back up just so I know its done.
I haven't tried this method but to backup and restore all installed apps check this Link.

Actually, if all you want to do is switch carriers (same GMail address), then a firmware swap will work.
I have an ex-Verizon (blacklisted IMEI - previous owner)S7 that I was moving to Tracfone (which uses both VZW and T-Mobile towers) - naturally, VZW was a non-starter; however, the UnCarrier was fine, so I used a T-Mobile nanoSIM (Tracfone triple-punch SIM kit includes SIMs from all except Sprint) and replaced the VZW firmware with T-M firmware (Prince Comsy ODIN does the track rather neatly). As long as your IMEI is not blacklisted from the TARGET, such a swap will always work.

S8 plus ussd problems, call forwarding

Hi first post here but not a complete newbie. But this time I'm stuck big time and would appreciate some help.
I've got a s8 plus that recently started playing up. All of a sudden it started not being able to make or receive calls. But I noticed it only happened when the "conditional call forwarding active" message didn't appear when dialing. I figured it had something to do with call forwarding so try to change the settings on supplementary services settings but when I tried to enter the settings an error message appeared "failed to read data" I tried sending the code manually to cancel voice mail *#022# to see if it would work but I got "connection problem or invalid mmi code" so assumed it could be that the phone is trying to check with the network the forwarding settings as the call starts but for some reason it cannot communicate with it as the mmi codes don't seem to working?? (I'm not that knowledgeable in that area) I tried all the fixes online for the "connection problem or invalid mmi" but none work so I flashed the firmware through Odin even tried a few different ones, I've been playing around with Odin for a while so I'm comfortable with it, I even flashed a pit once for a note 4 that was bricked (just saying so you can see I'm comfortable with using it, not an expert just comfortable) but nothing has fixed my problem my phone is a g955fd running pie and one UI with the latest security update. I've read the duos have some issues with this. I've tried other sim cards on my phone from different carriers and the problem is the same and I'm using my sim on a borrowed phone and no problems. I'm assuming the problem goes deeper than the firmware, could this problem be boot loader related? Would a nand erase and reinstalling the boot loader fix it? Everything else works 100%
Someone please help me, the phone I'm borrowing is an apple and every day I have it I feel weaker and dumber, it's like kryptonite.
Sorry for the long post but I've been browsing xda forums for years and I know that you guys always say to share as much info as possible. By the way I've searched and couldn't find a thread about this but it there is one I promptly apologize and just ask for the link to it if not thanks in advanced.
? G935F or G935U exynos vs snapdragon
Way for snapdragon
Flash https://forum.xda-developers.com/galaxy-s8+/development/rom-t3901074 with odin and test with hard factory reset recoery.
After, flash odin last firmware stock sammobile
Thanks
Thanks for your reply deadedge7
As I said my s8 + is a duos g955fd variant and has an Exynos processor, I'm not sure that rooting it would make much of a difference, as to my understanding rooting doesn't really change the boot loader it just allows you to install a custom recovery and roms. Which is not much different to reflashing a stock rom for all intents and purposes , but I might give it a try anyway. I guess that maybe a rom like the one in the thread you shared might give me some more hidden codes access as a root but I'm not sure. I will try to find a root like it for my variant unless you know of one and can point me to it.
Thanks
Hard reset or flash stock software or hardware problem
For iemi best way is root efs with flash twrp best way for /EFS

No solution so far. I've rooted the phone and install a couple of custom ROMs but still nothing. I'll try and roll back the firmware and see what happens. I'm no expert but I still think it is fixable. If I find a solution I'll post it on this thread. If you find one please share. My solution at the moment is getting a galaxy A50, very comparable performance with the S8 and really cheap.

I'll keep that in mind. Couple of things to note: I don't get the message conditional call forwarding active. I don't think I ever have.
I tried a different carrier SIM card(T-mobile) and it worked (I'm on At&t). I was able to make and receive calls. Even tried an out of country SIM card and received calls. But my At&t SIM works on other phones perfectly. Go figure lol.
The only other reason I can think of is maybe cos it fell a couple of times from the couch. About 1.5ft. New case kept making it slide off.
Install (Phone INFO SAM).apk
check csc if they are all the same operator
