Can I install T-Mobile ROM on US Unlocked S8 (SM-G950U1) - Samsung Galaxy S8 Questions and Answers

I have the US unlocked S8 (SM-G950U1). I use it on T-Mobile. If I put the T-Mobile ROM on it, can I later put back the unlocked ROM? (I suspect this question is probably answered somewhere on XDA but I didn't find it.)
Thanks
Charley

If you would check some threads there are answers to all of your questions.
1. You can use Odin to flash the 930U firmware on a 930V. The 930U is the unlocked version of the phone that will work on any carrier's network and has no bloatware.
2. The most current update for the 930V is PF2.
3. Google released Android 7 only yesterday so it will not come to Samsung devices for 2 or 3 months at the earliest.

1. A Verizon S7 930V will never be sim locked. No Verizon phone will be sim locked. If paid to have it sim unlocked you were misled. If your phone was sim locked you do not have a Verizon S7.
2. There are a few threads with the information about flashing the 930U firmware. If you cannot find it you did not look very hard. There is a thread a few below this one.

Here is about all I can find from someone reliable.
http://forum.xda-developers.com/showpost.php?p=68150390&postcount=866
--To me this says - it should be fine to flash the full US Unlocked RUU/firmware, which is x.xx.617.x, I think the latest is 1.91.617.1
I personally have flashed the pmic-8996-1.img from multiple firmwares including, International, US Unlocked, and Tmobile testing out WiFi drain. So, some bits are ok, but the aboot.img (bootloader) contains the partition, so anything other than VZW or the US Unlocked could result in a brick.
Until someone takes the plunge and reports back, or unless their are people out there whom have done this but not seen the posts asking the question. So hopefully if they are out there they will see this thread and comment.

Reviving this to ask a related question:
Can I safely flash the latest U.S Unlocked radio to my VZW 10 which has the latest VZW firmware?
If you flash the unlocked radio you will most likely lose all your verizon features such as volte and so on I would not if you use verizon services. For what purpose would you want to may I ask ? If you want to run your Verizon version on At&t or Tmobile there are threads on both I believe, but you should have support for other carriers already I believe as I think you will just get a non Verizon sim message is all but AndyBones can direct you on how to remove that nag.

I'm not actually using the phone on Verizon network, I bought it second hand and using it on Rogers network in Canada. Everything runs fine including LTE, but reception is weaker than on my M7 (purchased from Rogers) hence my wanting to try the U.S Unlocked radios to see if things improve. Similarly voice call quality is not that great though it has improved with the 1.82 firmware upgrade.
I don't mind testing out the radio myself, just need some assurance about being able to without bricking the device due to firmware mismatch or other incompatibilities. As pointed out in this thread very little information exists out there from people who have unbranded their VZW 10s or flashed non-VZW radios.
Have you tried running the latest RUU for the Verizon HTC 10 ? This may fix your issue if you have not already. Also I think on another thread Dottat posted a method to reset your bands of some some if you look on his thread for being able to use the unlocked 10 on Verizon he has it posted on there I believe. Resetting the bands or modem has worked for some people with issues with signal.

I'm not having an "issue" per se, I just want to see if I can get improved reception with a new radio, so I don't think an RUU flash would change much (I have already reset my modem for a separate issue).
Thanks for your help, I'm hoping that andybones or another dev can answer my question about being able to flash a non-vzw radio safely.

Is Rogers a CDMA based carrier (I legit don't know). You may need to do an entire us unlocked swap, not sure if anybody has tried that yet with a vzw phone.
No Rogers is a GSM network but my VZW 10 works fine on it.
If by debranding you mean to convert it to US Unlocked version, then Straightforward answer: Yes. You don't need to read further if all you needed was a yes or no, but I felt I should post what I did to convert it to US unlocked from Verizon for others who might need help.
Verizon 4G LTE devices are already unlocked. So, just to be sure, I S-OFFed my device first via sunshine. While S-OFFing, I chose the option of S-OFF with locked bootloader. Then I changed the CID to BS_US001. Didn't have to change the MID as it was the same as US unlocked version, i.e. 2PS650000. Flashed latest TWRP (for nand backup just in case). Flashed US unlocked RUU 1.8X.617.X. Successfully updated to 1.96.617.2 via OTA.
One thing that I immediately noted after converting to US Unlocked version was that the option of OEM Unlocking which was previously not present in the Verizon version became available in the Developer Options. Hope it helped.

Hi GrimJoke,
Thanks your post! Since I last posted here I've managed to do exactly as you described and ran the Unlocked RUU, updated to 1.96. Now running stock ROM and everything works great, and in fact the phone runs better than it did on vzw software.
I've noticed the same regarding OEM Unlocking. I read from Captain Throwback here that we should now be able to unlock the bootloader with htcdev and with superCID 22222222. I won't try since it's pointless for me.

Flashing international Firmware

Hello everyone,
yesterday, a family member gifted me an s7 from the USA (SM-G930P). He bought the phone off SPRINT as a SPRINT unlocked version, and, of course, because I live in Europe and want to use the phone with a European SIM card I have the "hands free activation" mark that is sitting on the top left edge of the display. I also noticed some changes, for example the "mobile data" toggle is nowhere to be found and also I don't have the options to choose the network mode (2G/3G/4G). I love the phone and I also would like to keep using it, I only need some answers from you guys.
My first question is, if the phone will actually let me use 4G network with my European SIM card, or will I be limited to 3G?
My second question is, If I can flash an international firmware for another carrier and another country on the phone, and if so, will I have the advantages of that firmware, like the Mobile Data Toggle??
Thank you very much for your answers.
If you install the 'Network' app you might be able to change the network type.
In general you should be able to use an unlocked P variant with a foreign SIM but you may have to activate with a Sprint SIM first.
You can't flash the international version since it's Exynos and the P version is Qualcomm CPU.
I am not sure if this model has Samsung region lock which is another thing to consider.
If I was you I would try to flash the U firmware (US unlocked) as it has the most support for international 4G bands among the Qualcomm US models. It also doesn't have all of the Sprint bloatware on it.

Thank you for your reply. I am currently using the European Sim from my carrier and I have no problems with it. I managed to get rid of the Bloatware by using Package Disabler Pro, but it still sits there somewhere on my phone. So far, the phone is working very well and other than the bloat sitting on my memory and the lack of LTE, I have no complaints.
Can you tell me if someone has tried to flash the U firmware on a P model with success?

Could you tell me how you did it, or link me a guide??
I had bought an unlocked Sprint galaxy S7 (930P) off ebay which died on me. Got it repaired from the service center and they sent me a locked device instead. The phone is currently on Software Version - G930PVPS4BQC1 and the hardware revision is Rev 0.6. I'll be using the phone in India and have a few questions.
1. I need to get this SIM unlocked from a service online. Does anyone know of a reliable place to do so?
2. If I flash the U Rom on it after unlocking it, will I lose the unlock? (I don't mind downgrading from Nougat to Marshmallow)
3. Should I unlock first then flash the ROM or flash the ROM first and then try to get it unlocked?
4. Will flashing the ROM directly unlock the phone itself?
Please advise.
...
you could try gsm zambia to unlock your phone it works i tried it myself a few days ago, also after my phone got unlocked i flash the U firmware/rom and the unlocked remained. so you should unlock your device first then flash the U firmware :good:
PS. if you one nougat better to downgrade if you can do marshmallow so when you wont have any issues flashing to U firmware. :cool

Flashing stock firmware on carrier locked phone

Hey everyone! I'm somewhat new to XDA (as in this is my first time creating/posting a thread) but I've decided this is the best place to get some help.
So, I have a carrier locked G935W8 Fido phone, and I was wondering if it was possible to install the stock G935W8 firmware from sammobile. I have read around that flashing the stock firmware works after the phone is unlocked, but what if it is still carrier locked? Can I still flash the stock G935W8? Or will I brick my device? My phone is not rooted btw.
Thanks to anyone that can help me out!
Welcome to XDA
yes, you can flash stock firmware as long as it is for the locked carrier.
Other firmware will work but the imei maybe effected.

Well, that's the thing. I want to flash the unlocked Canadian firmware, as in the one with no carrier bloatware. Will that be possible and have the phone working 100%?
I'm afraid I don't have an answer to your question, but I just did the carrier unlock on my new G935W8 a few days ago using basically the first website to come up in a google search. $25 USD; waited about 18 hours to get the code. You don't have to rely on your carrier (with their insane fees and/or waiting periods) to unlock your phone; might as well just do it. Having an unlocked phone is very handy if you travel at all.

yes, it will work for most things 100 %. volte may not work as it requires a carrier branded firmware.
you will probably have to enter the number for your voice mail manually and settings for internet as that is in the carrier branding.

Got an AT&T phone on ebay, LMV350AWM, want to flash brazilian LMV350EAW ROM on it.

Got an AT&T phone on ebay, LMV350AWM, want to flash brazilian LMV350EAW ROM on it.
So guys, the V35 was my dream for months, and finally got an Ebay unit that fit can ship here. It's already coming.
I read that LG imported to Brazil the AT&T version, not the korean, with jut a Br ROM on it.
Will this flash work? need the unlocked bootloader for this ? or just LG software ?
You will save yourself some serious inconvenience by making sure it really is sim unlocked before flashing away from the AT&T rom. You can read about someone else's experience on that here:

Tnx for the link. I've received info that the phone is fully unlocked, and already tested in Brazilian carriers. The previous owner already lived here and used the phone here with no issues. Will keep reading about it nonetheless
Hi mate, I also got an AT&T from USA, (I live in Spain) and I flashed V350AWMH10a_05_TCL_MX_OP_0124.kdz ROM from mexican carrier Telcel.
I use patched LGUP, and it works fine. No unlock bootloader needed.
Also is an Oreo ROM, not Pie, but I prefer, because Pie Roms had problems with call recorders app.
