Is there any way to get wifi calling on att with an unlocked s9 from best buy? Flashing att firmware or would it be best to get the att model? Must have wifi calling for work reasons and I hate all the bloatware but might not have a choice.
at&t probably blocks it, if you don't get their version. I have an unlocked, but on T-Mobile, and it works.
I flashed the AT&T firmware on my unlocked S9 and wifi calling and video calling worked.
With the stock firmware on the unlocked S9 nether option was there
Can you point me in the direction of a download for the stock firmware for AT&T? I'm wanting to do the same as well, but feeling pretty clueless about where to obtain it. thanks!
Same here. It works for me on T-Mobile
If I flash the att firmware will I still get firmware updates?

if you flash the att firmware or buy it straight from att you will end up a device supporting the same capabilities. So it's down to your tech skills or budget.
Where can I find the latest att firmware? I did not see it on sammobile.
How to
Step 1 Go to this thread for Firmware (thanks @iBowToAndroid)
You will want to go to the link for the U firmware and find the folder with the AT&T userdata file (RB7) download the user data file and the full firmware.
Step 2 Go to this thread to get the modified version of Odin that recognizes the GS9 firmware files. (Thanks @mweinbach and Raymondf )
You will then flash the downloaded files from Step 1 in Odin, after flashing the firmware the phone will boot into recovery and you will need to wipe data and cache.
Thanks so much... that did actually help me... as a fairly tech savvy person who doesn't really get into this stuff much, the lingo I didn't know was leading me astray... I had come across that thread but didn't recognize it as anything that would help me. Thanks again! Onward to bricking my phone!

Thanks for the info. A follow-up question: is it possible to flash it back to the stock unlocked firmware? The reason is that I'll need to use foreign SIM card when I travel overseas.

I have unlocked version on TMobile and wifi calling works just fine.
Do you have to flash the att firmware to the unlocked version in order to get VoLTE? I don’t care about WiFi calling, just hd calling and being able to stay on lte when making a call, rather than have it drop to HSPA during the call.

Probably wont last. Unless att has an imei number from an wifi calling att phone on that account it will eventually go away.

I understand, but unless att has changed its policies in the last month, if u do not have an imei number on that account that is an att phone with wifi calling it will turn itself off as soon as your phone is interrogated by the network. Theres 100 threads on it , applies to unlocked s8, s7, etc...
Toggle is there because of firmware, not because it works.

Any help/guidance for me??
I have tried a few times to use the March 2018 RB7 files with the ATT user data to get my phone to ATT stock - primarily for the Enhanced LTE (data and voice at the same time), as well as Wifi Calling. I can't get that version to load. I did get a more recent version to load (RK1) - and maybe that is the issue. Just wondering if there is a newer set of files and what specifically I should use (AP,BL... UserData) to get the phone fully set to AT&T. I now have the wifi calling option, just can't get it enabled. Any help is appreciated.

When you try to enable it do any of the AT&T Wifi calling configuration screens pop up?
I've read that the Galaxy S9 hardware is identical for all carriers in the USA.
If I bought a factory unlocked Galaxy S9 can I flash it to the carrier I am using (Verizon, Sprint, T-Mobile, AT&T) to enable carrier specific software and features? Can I flash it back to the unlocked firmware?
I already see a thread about flashing the unlocked firmware to carrier models so I am assuming there are no issues there.
Can one carrier model be flashed to another carrier model?
No, bootloaders are different, with the S7 there was an unbranded U firmware that was compatible with most of them, unlocked firmware will be that one for the S9, but no you cannot just flash different device firmwares to the wrong model
I was able to flash the ATT rom onto my Verizon S9. I got a VZ s9 from work but I'm on ATT. For the most part it's worked great, I had done the same thing previously with a Galaxy S7. I say for the most part b/c I am on here tonight to post a question myself about the fact that I'm getting a delay with MMS messages. I imagine it has something to do with the APNs I have setup, but I can't seem to figure it out.

Did you have to flash to the U1 software first?
I do think that is what I ended up doing... tried to go directly first and it kept failing. Got fed up and decided to just try and put the bone stock rom on it, and that went on really easily.... so after using it like that a few days I tried to drop the ATT rom on it and it worked without issue.

Yes, but you need to go to the u1 firmware 1st then to the other carrier firmware. Also make sure you avoid the newer firmwares with the new bootloader, as the unlocked model and certain carrier models don't have the new bootloader.

I tried downloading vzw firmware G960USQS3ARI6 to my unlocked sprint s9 and still not vzw flashed. want to do this so can have voice over LTE. Any other steps im missing? flash went through but still sprint
As soon as Firmware ver. 3 came out for the G960U1, I was able to flash it to my Sprint G960U and finally have VoLTE, WiFi calling and stable LTE for MetroPCS. Used samkey to unlock it from Sprint. My phone is actually performing much faster without all of Sprint's bloatware hogging my RAM and storage space. I can confirm that OTA updates still work the same...I received September's security patch (current) with no problems. Device is still official status and Knox hasn't been tripped.
A lot of people think you can just flash the carrier firmware of your choice and boom, it works...I had the same thought process....that's not the case. You have to make sure that there is a matching firmware version for the carrier you want to flash to, as well as make sure the G960U1 firmware version (the unlocked version of the S9's software you have to flash first before even carrier flashing) is the same version of what is installed on your phone now. It's easy ya'll......just READ lol.
I'm in love with my phone again thanks to XDA. ?
HAPPY FLASHING!

Well first off, you have the unlocked phone. I don't. My G960U is originally from Sprint, so I'm not sure about carrier flashing regarding the G960U1. I thought it was supposed to provision itself after you put the sim in, and the associated carrier apps will download since it's the unlocked model...but I may be wrong...

I know so many people have already answered your question from some saying No to others saying Yes but you need to Install U1 first and Bla Bla Bla.
I want to give you one specific answer: With S9 you can any Carriers firmware you wish or even Unlocked phone's firmware. You will never have any issue. And you don't ever need to flash U1 or something else before changing carrier firmware you can Flash from ATT S9 firmware to VZW S9 firmware without any issue. You can also flash from U to U1 which is from Carrier specific to Unbranded/Unlocked but only hiccup is original Odin will give you SHA-256 error, which is normal because you are flashing U1 firm to U device or vice versa. This error can easily be resolved by used Patched odin that disabled SHA-256 check. And trust me you will never have any issue.
You will never want to do this but I have gone as far as mix-matching U and U1 firmware together as well. Like flashing AP, BL and CP of U device but flashing CSC of U1 device. and it still works.
hey there, a little late to the party, having trouble with going from a Verizon to a Sprint, even by way of U1. I can't get any of them to work. And I've been told I have to go from VZW to U1 before I went to Sprint. Is that not the case? I'm having a hell of a time getting anything to flash, everything fails.

You can with a unlocked bootloader. But to go back to Sprint you need the official firmeware which they do not provide to the public.... I have a G7 had it unlocked, different firmware installed. Had no service, . Tried to flash another firmware and ended up wiith a hard brick.. Got it back to the first unofficial sprint firmware, then had to have Sprint reflash the official firmware for the phone.. What's nice the bootloader is still unlocked.. Right now I would not even try anything. Best bet is to return if able, and buy a already unlocked version, so long as you can use it with sprint.

Man I just bricked the phone, first I tried flashing G710EM using LGUP and Partition DL (Select All) it failed almost immediately, after rebooting the phone it booted straight to Firmware Upgrade mode. Then, I got G710N20f, also tried to flash it using Partition DL (Select all), this time it failed at more than 70% step BackupGPT, now when I reboot the phone, I get the LG logo but after the screen turns to whitenoise like, it seems like it is still in Firmware Upgrade as I can still connect to it using LGUP.
Any ideas how to unbrick it? :crying:

Are you sure it is firmware (bootloader unlcok)? or sim unlock, there is a difference.. If you did a bootloader unlock you will get a waring saying. "Warning your software can not be check or is corrupt, please relock the bootloader". If you don't have this kind of message of this sort, then you just had it sim unlocked.

im just going by the ebay listing. It states"Your phone will be converted to a unlocked firmware version and that i can no longer receive ota updates".
My software version is G710ULM11e and my build number is OPR1.170623.032 and im on security patch level july 1, 2018 and android 8.0. When i go to the update center to check for a software update it states im using the latest version for my phone.
I did try a prl update and update device config and it states profile cant be updated. SprintDM notification shows that it trying update mobile network. it comes on and off every 3 mins or so.
I hope this is enough information to go off of! If you need me more information , please tell.
Also I did contact sprint via chat and they stated i could get my firmware back to stock but its 2 about 2 hours away from my city . itll be a like a whole day trip for me since i don't drive and would have to take a bus. I would love to avoid that.
Thanks!

that problem with the Sprint DM trying to connect every couple minutes is a huge problem with the bootloaders be unlocked you will have to go to Sprint and have them do it it takes about 30 minutes because right now there is no firmware available for Sprint anywhere on the internet. when I get a break from my new job I am going to try and install TWRP on my device and if I do it successfully I will be able to upload some firmware but that's not guaranteed.

Whether you had insurance on the phone or not should not have mattered. Sprint should have flashed the firmware, cuz that's their damn job. They asked me the same question I told them no and they still flash the firmware.

You have to be assertive or act completely aloof. If you are a paying Sprint customer, they will reset/reflash your phone. If no one in your immediate area can help you out, maybe you can mail the phone to someone who can get it serviced (heh I'd happily do it for free but hopefully there is someone a bit tech savvy in your own social network).
Hi All,
I have Samsung S9 Unlocked T-mobile from US and currently in India. Currently i have Oreo Version.
As all know, it doesnt have VOLTE option enabled which is needed for my sim network for voice calls to go through.
Somewhere i read Pie update will have VOLTE option and hence i am trying to update to Pie update.
I downloaded G960USQS6CSGB firmware for T-mobile, but before upating firmware using Odin, i got doubt if it will stick to T Mobile after update. This will make my phone not usable in India.
I tried to check online, but couldnt get direct answer and hence posting in new thread.
Can someone help clarify if it will lock the mobile to T-Mobile or will the phone be still in unlocked state?
Also i see two CSC files in the firmware folder. CSC and HOME_CSC. Which one to use?
If I should update with some other firmware for being unlocked and yet to get PIE update, please point to required firmware name or links.
Also will updating to PIE update will have VOLTE option ? Kindly confirm.
Thanks in Advance.

csc will factory reset your phone, home_csc wont
volte wasnt removed from pie, so that shouldnt be an issue
the firmware version you posted has the 6th bootloader revision, im betting here is a 7th available for your phone, but the 6th version should be fine as well
as far as the unlocked state of the phone goes, it shouldnt re-lock, but im paranoid lol. Have you looked into the U1 versions of the phones firmware? Theyre inherently unlocked firmwares and dont have any of that irritating bloatware **** in them

if it has no financial obligation to any carrier and the phone locks to that carrier, then the carrier it locked to would be required to release it. I cant imagine how it would lock to t-mob tho
Factory unlocked phones stay unlocked, no matter what firmware you flash.
Carrier locked phones that were properly unlocked by the carrier (they provide the code to SIM unlock the phone) will stay unlocked, again, no matter what firmware you flash to it - as long as it's compatible. Flashing the wrong firmware may just brick the phone. But, at least it's still SIM unlocked.
Phones that had some kind of software hack installed to trick the phone into thinking it's unlocked will lose the unlock status when you flash a firmware that also wipes the phone. Then it will come back as carrier locked again, because the hack is gone.
That last case is the only case I know of that will "re-lock" a phone. I've never heard of a carrier unlocked phone spontaneously re-locking under any circumstance.
Hi,
Thanks for the details. I tried to flash G960U1UES6CSG4_G960U1OYM6CSG4_XAA firmware. But while loading AP file in ODIN, it gave some error. Couldnt understand what is the error as its in chinese.
Then i loaded G960USQS6CSGB_G960UOYN6CSGB_TMB firmware which i downloaded previously. This got loaded in ODIN without any issues. And i am able to flash to phone. On rebooting, saw that phone moved to Pie version.
But i couldnt find VOLTE option (Enhanced calling) option. Does anyone know which version will enable that option?
Or anyother way to enable that please.
Thanks in advance.

Factory unlocked phones stay unlocked, no matter what firmware you flash.
Carrier locked phones that were properly unlocked by the carrier (they provide the code to SIM unlock the phone) will stay unlocked, again, no matter what firmware you flash to it - as long as it's compatible. Flashing the wrong firmware may just brick the phone. But, at least it's still SIM unlocked.
Phones that had some kind of software hack installed to trick the phone into thinking it's unlocked will lose the unlock status when you flash a firmware that also wipes the phone. Then it will come back as carrier locked again, because the hack is gone.
That last case is the only case I know of that will "re-lock" a phone. I've never heard of a carrier unlocked phone spontaneously re-locking under any circumstance.

Hi,
Thanks for the details. I tried to flash G960U1UES6CSG4_G960U1OYM6CSG4_XAA firmware. But while loading AP file in ODIN, it gave some error. Couldnt understand what is the error as its in chinese.
Then i loaded G960USQS6CSGB_G960UOYN6CSGB_TMB firmware which i downloaded previously. This got loaded in ODIN without any issues. And i am able to flash to phone. On rebooting, saw that phone moved to Pie version.
But i couldnt find VOLTE option (Enhanced calling) option. Does anyone know which version will enable that option?
Or anyother way to enable that please.
Thanks in advance.

if your Odin error messages are in Chinese, youve obtained a modified version. Itll probably work, but youll get that Chinese stuff whenever it needs to tell you anything. I dont know which versions have volte tbh. Sorry man.

Thanks youdoofus for trying to help. For me atleast it didnt get locked when i moved to Pie. I will try other methods.
I will try to root the phone for enabling volte, but the methods that i tried didnt work.

yeah, sort of. The CSC's on these things are weird. Im starting to believe that these new versions of android are just like windows ISOs where they have all the versions compressed into one file and it uses a directory file to tell the firmware which version to install. Im sure a code writing dev can confirm or deny this thought, but at this point its merely a weak theory

I got Note 10+ 256gb unlocked version from Samsung. Planning on using it on Tmobile. Do I need to do anything specific to make it more compatible with Tmobile. I've currently unlocked s10e on Tmobile and overall network coverage seems bit subpar compared to Galaxy S8 that I purchased from Tmobile.
So I'm just curious if I need to do anything for Note 10+ ince I get it, to make it more network friendly.

Download the tmobile firmware from sam mobile and odin it to your unlocked.
I googled it but didn't have luck. Any chance there is a link to the T-Mobile firmware?

It's not up on Sammobile yet...
But it is on samfrew
https://samfrew.com/download/Galaxy__Note10+__256GB__/c3pb/TMB/N975USQU1ASGO/N975UOYN1ASGO/
What about for the 512 version unlocked? Can use same as 256 unlocked?
And is it recommended to flash the firmware (T-Mobile in my case too) right out of the box or do you have to put your old sim in from your previous phone first, then setup your gmail acct and let the sim reach the T-Mobile network?
Never had unlocked phones so this will be a first, hence the questions...
I just flashed my Note 10+ with TMB fimware and it all went fine. here is the link from Sammobile https://www.sammobile.com/samsung/galaxy-note-10-plus/firmware/SM-N975U/

It doesn't really matter. The storage size doesn't affect the firmware. It's all the same.
Flashing the carrier firmware will factory reset your device, so I wouldn't waste time setting it up first. Just put your SIM in and let it provision for T-Mobile. It happens automatically so there's nothing you have to do. Then flash the firmware with ODIN.
Just research and make sure you know what you're doing before flashing. ODIN is fairly fool proof, but it's still best to know what you're doing first.
Add each file to it's respective field in Odin v3.13.3. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.
I thought you can flash without messing with your data.

Technically you can flash without messing data but will be difficult to identify the reasons if you encounter any issues after that. So its better to flash it now itself when its freshly out of the box
I was going to update the Unlocked firmware via OTA software update. Once I receive the update I will then flash the Tmobile firmware via Odin

Just received my unlocked Note10+ 512GB an hour ago and, as was the case with my unlocked Note9, it works great out of the box with T-Mobile and Mint (a discount reseller). No custom flashes needed unless you want the TMO bloatware. I would leave it as-is and just download the respective carrier apps individually. Love this BEAST so far! :good:
I bought the note 10+ and i'm on the tmobile network. The only issue I'm having is VOLTE. To my knowledge VOLTE should work. Can anyone confirm this?
