I recently bought an unlocked ATT Lumia 950. Is it possible to flash the device with retail MS firmware or whatever is bloat-free that comes with retail devices? Any help would be hugely helpful.
The reason I am asking this is because I would love to have a clean MS released OS installed in my device rather than the one tweaked by ATT. I am using this device in Canada and I don't need ATT tweaks, Welcome screen, settings and Apps. Also by having a clean OS not attached to any service provider, I can get updates as and when MS pushes them.
I also remember reading in some forums that ATT Lumia 950 cannot be installed with MS retail OS even if they are carrier unlocked. Is that true? If it isn't true, can any of you reading this point me to a forum or link where I can follow steps to fresh install my Lumia 950 (ATT Unlocked-using it with Fido network in Canada).

Hi guys,
I just got my Optimus 7, and I managed to do a simple debranding to get it to NoDo. However, I forgot that ChevronWP7 doesn't work on NoDo (I've been waiting for my student developer account to be approved, but it is taking too long), and I plan to downgrade. There are selections of ROMs in the development section, and I have downloaded a few of them, but not sure which one to choose. Can anyone suggest which one is suitable for my phone? Also taking into account the possibility of future updates, which region will get the update the soonest?
FYI, my phone is bought through Singaporean carrier, but weirdly enough, was branded Optus Australia (that is why I had to debrand, as Singaporean carriers already had NoDo, but not in Aussie yet).
Thanks...
Oh, WAIT! Do not DO IT!
Hahahaha.
LG Optimus 7 does not need that buggy Chevron unlock.
Visit the developer forum for this device, just a couple of lines under this one, and you will find a MUCH simpler way of unlocking your device.

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

Bought "Unlocked" phone, has sprint branding, seller insists that's how Samsung works
Hi everyone, I bought a Galaxy S10+SM-G975U (same model that all 4 major US networks use) that was sold as "Unlocked" without specifying that it is Sim unlocked, Network unlocked, or Factory unlocked. Most of the time unless a seller specifies which unlocked then it means the phone is Factory unlocked, I gathered this from 9 years of buying and selling Android devices so it's not just a guess.
When I got the phone Sprint OMADM pops up and tells me I have an incomplete activation, "about phone" told me it was Sprint Network Unlocked; after a week it now says unknown under "Brand" in the "status" section.
The seller said that when you buy a factory unlocked Samsung phone and put in a network sim card that Samsung then loads the branding (bloat in my opinion).
1. Is this true that Samsung could have loaded Sprint OMADM?
2. If true can I remove it so that I don't have to "Force Stop" it after each startup?
3. Is there any piece of software or database that I can look up the origin of this phone so that I can either change my eBay review of the sale and apologize for my mistake, or affirm that indeed the seller failed to disclose branding that he knew wouldn't go away when a buyer puts in an ATT simcard such as I have.
I've read one single thread by a user and not a Samsung official that claims that you can pop in a network sim card and then restart to change some software but I have not found even one more thread mentioning this phenomenon.
My background:
I've bought factory unlocked my Moto Pure X and a OnePlus 5 and neither did any ridiculous **** when I switched networks, so that's why I doubt this claim.
I bought a AT&T branded one for use on TMobile. It kept popping up errors. I flashed the unlocked firmware and it works great. I get unlocked updates and everything. You'll need to look on here but there's a walkthrough somewhere. But there are a few advantages for running the carrier branded version so you could flash the AT&T firmware instead. I wanted less bloat so I went with the unlocked one.
Think this might be the thread:
https://forum.xda-developers.com/s10-plus/how-to/sm-g975u-firmware-downloads-tmo-spr-att-t3908657
That said after I did all this I did read there was going to be a update to the firmware which would do what you described.... Switching firmware based on the sim card. Never seen it happen on mine still on unlocked unbranded firmware. Maybe this phone is running old firmware prior to the update that implemented this?
not normal. LIke you, I purchased an 'unlocked' phone and when I powered on, it was a Verizon phone. I popped in my TMo sim, and it worked OK, but I would get the annoying Verizon popups reminding me that I'm on on their network. I installed the unlocked firmware and it went away.
But there's more: when the phone had a problem, I sent it back to Samsung under warranty (still unlocked) and when it was returned, I just installed the original sim and powered on. Now it seems to be a TMo phone, and when I look at the phone's software version, it shows TMB/TMB/VZW. It's been receiving OTA updates and I've disabled bloatware, so I'm OK with it.
Just to be clear I'm not going to flash anything. I'll just turn around and sell it. I need a stable phone for work and I used to mess around with flashing different roms and while it was fun it was a frequent activity and I don't have time for all the annoying trouble this phone has been. Thanks everyone.
Flashing rom is different from flashing a stock firmware. In your case the only way to be completely off from the previous network you are getting the notification from is to flash a G975U1 or G975U stock firmware which is unbranded or your network branded respectively and you are good to go. I switched my yesterday and am okay ?. I will be happy to assist should you change your mind

Thanks. I'm going to see if it will sell first.
I have an old Tmobile S7E on old ass firmware (Android 7.0 BQE1) and it's already rooted. I just went through Tmobiles Device Unlock process and I believe the phone was unlocked successfully. I'm looking to upgrade to the latest firmware that still allows rooting. I've looked through the Custom Roms threads and can't tell which one is the latest. I am also wondering if I need to use Verizon firmware or stay on Tmobile firmware.
For instance, this thread here: by jrkruse, he mentions to another user in the comments "This one or verizon one? This one just has the Tmobile csc stuff added and a build.prop for gsm carriers thats it" so it made me wonder if I'm using Verizon service but it's a Tmobile phone if this would work. I know Verizon is CDMA so him saying gsm carriers made me think it may not work.
I know this device is old and this thread doesn't get browsed as much anymore so hopefully I can get some answers. If I can't get this working I guess I'll just be getting a new 2020 model phone :highfive:
Thanks guys!
I'm just having a really hard time finding an answer. I just had a OnePlus 6T T Mobile edition find it's way to me. It's carrier unlocked and Bootloader unlocked and it's running the latest T Mobile version 10 OOS. Since the bootloader is unlocked, can I just flash the latest non T Mobile OOS Android 10 version to it? In other words the US 6T edition? Or must I use the international version? I'm really confused and sure this has to be answered somewhere but just can't find it. Can anyone help and point me in the right direction? I have lots of experience flashing ROMs, but this one has me stumped at this point. Thanks.
I'm no expert... lol, but based on what I do know, I believe these are your steps...
So I'd take a look at this post-
[T-Mobile / Guide] - Full SIM and Bootloader Unlock + Root for locked devices
Background: I am writing this short guide for people like me that want all the info about the T-Mobile 6T unlock capabilities. None of this is my work. I wanted to have a central thread where T-Mobile users can discuss the T-Mobile specifics of...
forum.xda-developers.com
Follow Step 4, and then from that point allow the ROM to update via OTAs. The MSMDownloadTools are basically a fix-all, but set you back in time update-wise.
I do not believe there's a full TMo ROM for the latest updates, but once again, I could be wrong.
You could also use the International Version if you want, that is what I am running now, but if you want root access, I believe getting 11 working has some extra steps/workarounds (so i'm still on 10)
I initially changed to International because of quicker security updates and it works fine, no issues to complain about, but my wife (on TMo stock) seems to get better signal than I do in more rural areas.

Thanks for the input. I have seen all those threads, but the main purpose there was for people who did not want to wait for the SIM unlock. That got them past that and also got them so they were able to unlock the bootloader. I already have an unlocked SIM and unlocked bootloader. So I know I could load up lineageos if I wanted to without doing anything special. I would think I should be able to use TWRP to put the International version on using TWRP. And maybe the US version. But that may not be the case.
It just seems like any work on this device stopped after the above. Of course once you are bootloader unlocked, there may not be need for much more and people may just move on to other ROMs.
Thanks.

The more I search, I guess that it appears there are some privileged partitions. This method you mention gets around that irrespective of the SIM and Bootloader being unlocked already.... Sigh....
