Sprint S8 Active flash to T-Mobile? - Sprint Samsung Galaxy S8 Questions & Answers

So i've read that the sprint version of the S8 Active is on bootloader v5 and the T-Mobile version is bootloader v1. Is it then possible to flash the T-Mobile firmware onto the Sprint Variant ?. The device is already unlocked but i would like Wifi-calling to work for T-Mobile.
Edit 1: Found this and successfully fully flashed from Sprint to T-Mobile(everything works including Wifi Calling). Only works if you are on bootloader version 1.

No apparently the bootloader version must match or be lower so in this case sprint is higher so you can't flash. I've tried and downloaded the tmobile oreo firmware; you'll just get a fail in odin

That is the part i am maybe not understanding. My Sprint S8 active says it is Software version G892USQS1ARC1. Doesn't that mean it is bootloader version 1?

Sorry I was wrong! I actually flashed it! Very happy right now. I was being stupid and using an older version of odin before. Now I successfully flashed sprint to t-mobile oreo with no problems! Use Odin 3.13.1; not prince comsy mod or anything else. So it was bootloader 1 after all; there were some misleading posts without proof. I will trust the software number from now on

ARE YOU SERIOUS?!?! Does wifi calling work for you now?

I'm not sure. How can I check? I'm on Fido which is Canadian carrier without WiFi calling. I'm guessing I'm supposed to be looking for a tmobile WiFi calling app. See attachment screenshot for proof. Still recognizes my phone is from sprint

Yeah i just finished flashing it and i get the same as you. Phone still recognized as Sprint and no WiFi calling. Darn. Android 8.0 Oreo is a huge plus however.

I think we need to follow this guide to change carrier but the thing is there is no factory binary for the s8 active so this guide won't work until there is one...
https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487

Actually I have found and flashed a factory binary trying to change it to T-Mobile. The problem I ran into is they want you to download the firmware with "w" after the model number. That is what I think let's you change the option after typing in the code. That firmware is only for s8 I think(not active as it has the s8 model #). Without flashing that, after I typed in the code the only option I had to choose from was sprint. No "xac" or whatever it was.
If I am not mistaken. The model with the "w" is the Canadian version of the s8. The s8 active is US only I think.

So Im getting ready to pick up a Sprint version to use on Att or Tmobile (good deal). Are you guys seeing any issues after flashing? Thanks

The only thing I've notice is there is no option for mobile hotspot( i don't think it was there to begin with, i could be wrong however). Other than that it works perfectly. Great battery life and everything. Flash the userdata to get rid of the Sprint Boot animation if you'd like. I did it and now there is just the "Samsung s8 Active" logo, then lock screen. Goodluck.

After flashing Sprint variant of the device to T-Mobile firmware, do all features work: WiFi Calling, Band 12, VoLTE and Band 71?

WiFi calling works fine on T-Mobile without flashing to T-Mobile firmware. Only issue is that sometimes it gets stuck enabling WiFi calling requiring a reboot. Band 12 also works, its in the Sprint specifications. The big question I wonder about is if band 71 can be enabled.

flash not working?

Did you follow the video I posted?. Ignore all the other comments about things not working. When i updated the OP with the link, it fully flashed the sprint device to T-Mobile. The only thing you have to watch out for, is if your Sprint software is running a new bootloader. You can tell by looking at the baseband version number. This will only work if you are on bootloader 1. My baseband is currently "G892USQS1BRD5". The bootloader version is the 5th character starting from the right. The number 1 before "BRD5".

Screwed up my SM-G930VL, please help!!

Hi,
I bought a SM-G930VL (tracphone branded, but verizon compatible) galaxy s7 for a pretty good price, however the advanced and wifi calling were not options (even though verizon told me they were before I purchased). I decided I would try to flash the VZW firmware from sammobile through odin, but it did not work. It originally gave me the ext4 error, but then flashing the csc fixed that. I then flashed the AP file, but it finished very quickly (about 3.5 min) and now will only boot into recovery when powered up.
Is there anything I can do to save my phone, or have I permanently screwed it up?
Thanks
holy sh*t got it working. Flashed the BL, AP, CP, and CSC files and it booted to welcome screen!!
Thanks all (and hopefully this helps anyone in the future who runs into this predicament)
It is currently checking wifi connection so hopefully all is well!
Edit: Is there a way to edit the title? That way this could be maybe help the next person rather than getting ignored.

Hi, want to ask a few questions. were you able to fully flash the Verizon firmware to this model with no issues? The phone is also supposed to be factory unlocked per my connections with reps.
Did the phone fully change to a SM-G930V, showing in settings and in Odin mode?
Yes I was able to fully flash Verizon and I have working wifi calling and advanced calling. In settings it shows up as V not VL as well. As far as I understand it is the exact same hardware just different software running on it

Great, i flashed one yesterday for a friend via teamviewer and even changed the model as SM-G930V in odin mode. So I guess due to this the phone has now a locked bootloader and ended up being converted to a full Verizon galaxy S7. Only thing it did not take his Metro PCS sim card. Unsure it would take any other carrier sim cards.

Was the boot loader originally unlockable? I was under the impression that all SD versions were locked down right. That's great that you got it to work also!

It seems it was as it allowed me to flash the verizon bootloader and full firmware. Normally tracfones only allow to flash part of a firmware and rejects all bootloader partitions.

There were reports of someone flashing the phone to an SM-G930U (Unlocked US S7). So apparently they are interflashable. I however have not gone to that extent as am yet to get my one to thinker with. I flashed previously to a SM-G930V via teamviewer for a friend. You can search the threads and verify.

You probably figured it by now, but MetroPCS is the only retarded carrier that locks SIM to IMEI. So if you want to use MetroPCS on any other phone than the one you currently have it on, you need to call customer service and give them your new phone's IMEI. Then your new phone will start working. If you want to switch back to your old MetroPCS phone you need to call them again and give them that IMEI, which is retarded. I don't know why they do that but it's really annoying if you frequently switch phones.
I have a 935V (S7 Edge Verizon) and now have 935U ROM on it using Tracfone. Initially I have Tracfone's Verizon service but I wanted the freedom to easily move from one phone to another so I converted it to a Tracfone-GSM(ATT) and been using it in my Verizon S7 Edge (with 935U ROM) and iPhone SE without any problem.

Could you add links to everything you used? I have the same model using straight talk and I want to be able to have a backup firmware to flash in case I ever mess up my phone (which seems to be a trend). And have you had any issues at all? Like, does everything work okay?

Convert SM-G930T to SM-G930A so I can use AT&T LTE bands.

Hi All, I want to continue using my AT&T prepaid plan but I recently bought a locked T-Mobile Galaxy S7 SM-G930T (I'm going to try to unlock it - if that doesn't work this is all moot). I would like to flash AT&T firmware so I can use the AT&T LTE bands. Can I follow the instructions in the link below once I've unlocked a T-Mobile SM-G930T and turn it into a SM-G930A?
http://www.droidviews.com/nougat-firmware-on-att-galaxy-s7s7-edge-sm-g930a-g935a/
I've read the link below... but it seems to be only if you want to continue using T-Mobile service which I don't.
https://forum.xda-developers.com/tm...w-to-flash-att-nougat-to-t-mobile-s7-t3553610
Changing firmware doesn't have anything to do with what bands the hardware supports. Unlock it and throw the ATT SIM in. Only difference is carrier supported features and software (wifi calling, etc). Flashing ATT modem might improve coverage but all S7 support the same bands.
Thanks buddy for the reply. I'm used to using a custom ROM on my Android phones so this is new. Mostly CyanogenMod.
That's good to know I don't need to flash in order to get the bands but I understand I need to if I want OTA updates from at&t. It seems relatively simple that you just flash the AT&T ROM over the T-Mobile with Odin and then use some update file. It doesn't even effect Samsung pay and Knox which is great.
Stupid question: is the AT&T modem included with the AT&T rom? Also, with regards to the 2nd link in the OP what is the update file that you put on the sdcard to use in recovery - is that an OTA update because your ROM is different from your carrier?

The following is the latest G930A Android 7.0 firmware file. All you need to do is flash it with Odin's AP slot to completely convert your G930T to a G930A. No other steps or files are required: G930AUCS4BQC2_CL10280464_QB12904132_REV02_user_low_ship_MULTI_CERT_meta.tar.rar

I don't get why you would do this other than to have ATT bloat over TMO bloat (IMHO TMO has less bloat than ATT). There's no technical advantage. Am I missing something?

The amount of bloatware is irrelevant since you can freeze all bloatware on either build. I experienced many issues on the TMo version including issues with Android Auto, Google Assistant, and Tasker. I thought these apps were buggy but all of those issues were resolved on the AT&T version. The AT&T version seems to be a better, bug-free build.

Read that in a different thread you posted to after I responded. I think it's very YMMV though. But if you saw improvement then ??
Hi, did anyone ever complete this flash from SM-G930T to SM-G930A? I'd like to do this solely to try and get the wifi calling feature since my workplace has poor cell service but great wifi. I bought the T-Mobile phone, unlocked it, put the ATT sim in and everything but wifi calling works fine. I appreciate the reply!
This is much later in the year (11-8-2021) and ATT has posted the list of phone they say will work and it only shows G930A. It seems their test of working means it must have been sold by ATT. They say My G930T won't work. So Will ATT continue to use customer's unlocked phones it they were not orginally sold by ATT. They have the records. Will ATT refuse to use one of their SIMs even if the phone is Flashed to ATT logo. I do not want to throw away my G930T phone.

Hello and thank you. You posted this information and link back in 2017 and so much has changed. Mostly ATT is now working hard to get rid of all 3G towers and firing up 5G. They said my Galaxy S7-GM930T would not work so I think they link you posted will help me convert the phone back to a GM930A or U or U1. My question is,..Has anything in your post changed since 2017 and if so could you please advise me of what I need to do. Thanks very much.

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

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

and can you re-upload the link is dead now
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?

Links for AT&T and Cricket USERDATAs

I know these are much tougher to find - can't be obtained from SamFirm or SamMobile. So I'll be uploading one for each carrier, for each bootloader version. Firmware is universal on U models so you can use the other 4 files from any other matching collection. Can probably even mix and match builds, if you can't find files for the exact same build. Can't mix and match bootloaders though, so the other 4 files have to at least be from the same bootloader.
USERDATAs for any other CSCs can be gotten from SamFirm - for the latest version. If you need an old USERDATA for a CSC that's not commonly found on SamMobile (ACG, LRA, TFN, etc), let me know and I can probably get it.
You'll need 7-zip to extract.

SC1 USERDATA was added a few days ago, for anyone wanting to jump to Pie
ATT USERDATA added for bootloader 6
bootloader 6 userdata
Sorry if I am posting in the wrong spot I am new to this forum but I was wondering if someone can extract AT&T userdata for Odin Product code ATT
PDA G950U1UES6DSG1
CSC G950U1OYM6DSG1
I had it for 5 and didn't realize that this upgrade was 6. I need my wifi calling because I am in the hospital a lot and don't have reception. Please help I would really appreciate it!

USERDATA only applies to U firmware, not to U1. If you don't have wifi calling while on U1 firmware, then you need to change to U firmware, with all of your carrier's bloatware
Cricket USERDATA added for bootloader 6

Thanks! I am not on AT&T but used this to enable future OTA upgrades. Other than the bloat (expected), it worked well.

AT&T puts blocks in their firmware so that OTAs don't work if you're not using AT&T service - even if it's one of their own MVNOs. So if you're not an AT&T customer, you do NOT want to be on their firmware
What are the restrictions on userdata? I assume that the userdata should much the security level? Is there any other restriction

It at least has to match the bootloader version. YMMV if the USERDATA isn't the exact same build as the base files
Sorry if this is a stupid question, but I have a SM-G950U1 (unlocked Galaxy S8). Can I use this to flash it to make it a SM-950U (ATT locked Galaxy S8)? I want to get the official ATT firmware to be able to use Wi-Fi calling and other ATT features.

It won't SIM lock it. And you won't get wifi calling. But you'll get most of the rest of their features

Hasn't been released yet. T-Mo and Metro are the only ones who have actually gotten a rev 7 OTA so far. But i'll definitely post them when I get access to them.
I did just notice that I had never uploaded the rev 6 Cricket USERDATA, so that is done now

U1 has gotten rev 7, yes. When I said that "T-Mo and Metro are the only ones" that have gotten it, I was referring to the carriers themselves, which is U firmware.

Well firmware is universal - there is no such thing as "Cricket firmware". But there are Cricket USERDATAs, yes. Only thing is that their S8 hasn't gotten the rev 7 OTA yet, so the Odin files haven't been published yet either

Flashing Sprint S7 SM-G935P to SM-G935U

Hello,
I am going to attempt to Flash my Sprint S7 Edge with current Firmware version G935PVPS8CRK1 to the Unlocked firmware of G935UUES8CRK1 as I have ported out of Sprint and need to enable all LTE bands for a different network now.
My questions are
Can this be done for the above firmware versions and will it enable all LTE bands if successful ?
In the SAMMOBILE page, there are different variants for the SMG935U including one for Sprint. I was assuming that all 935U variants would be identical, but I guess I'm mistaken. So, should I download the Sprint version of SMG835U or something else ?

Never mind, I was able to flash the G935UUES8CRK1 firmware. Also, in Odin I tried with the HOME CSC. Although Odin showed a successful status, my device went into a dm verity boot loop. Then I had to flash it again with the regular CSC file and it worked.
I'm about to do the same thing, were you able to use LTE and VOLTE? Or access other bands that didn't work while on the sprint firmware? Right now i have the sm-g935p and am using it with t-mobile. I can only get 3g speed and have voice working or LTE with no voice.
Yeah, LTE was working. Band 40 which was otherwise disabled in the Sprint firmware was open and LTE Discovery app confirmed it. Not sure about VoLTE.

Yes. The bootloader was updated a few months ago. There is a thread here with files and instructions.
