Unlocked samsung s7 flashed with T moblie filmware

Hi guys
I had a Samsung s7 with model number sm-g930t, But it had never been t mobile since I had it. and I am with Vodafone. Now Vodafone has set up the wifi calling and this isn't working because I think I have now changed my phone back to t mobile. Does anyone know if there is different firmware that I can use?

It will never work properly here (UK) as it's Qualcomm snap dragon and it was build for a different region.
You can attempt to install different firmware from UK or EU but it's really just luck if you get it to work or not.
To get wifi calling to work you will need to flash unbranded firmware, either BTU (UK) or XAS (USA). Even when you flash US unbranded as i said earlier it will not be fully functional in this region as it does not have the required hardware.

Do you have to unbranded firmware?

Yes if you want to use it in the UK.
Carriers in the US, T Mobile (US), Vodafone (US) etc DO NOT use the same connection standard as Vodafone, T mobile, UK. It is essential you understand this. There is no advantage to flashing UK network branded firmware, unbranded will give you all available connection options but not 100%.

I will give it a go. Do you know where I will find the filmware? been looking but can't find it

SamFirm tool is a good way to get the most recent firmware files from samsung servers directly.
Otherwise it's firmware rehosts like sammobile or updato

A51 Panama to Canada or US firmware

Hi, I'd like to flash the Canadian SM-A515W or the US SM-A515U firmware on my Panama SM-A515F model. Will it work or will I hard brick the phone? Thanks!

I believe the answer to your question is that you need to provide a firmware associated with the CSC code of your phone, but I'm pretty new to this. I don't know if you will brick the phone. I assume you will just have to reflash it to the appropriate image.
On a related note, I tried to change my phone's CSC code. The current code is GTO (Guatemala). The code list was Latin American countries only. So a question related to the OP: is it possible to change a phone's available-CSC-code list or is it 100% hardware dependent?

Contacts not visible

Hi there,
I am from NZ and I imported a Snapdragon model of Note 20 Ultra 5G from Hongkong or Taiwan. The model number is SM-N9860
I have my contacts saved at either using the country code +64 or by just adding a 0 in front.
In my previous phone, both of these styles just worked fine and the name used to display when someone called me. However, now....it's so random. Some of my contacts call me and all that is displayed is a number. Does anyone have a solution for this annoying problem?
In short, I am needing to edit the contact details of my saved contacts
Thanks

I had this problem when I flashed Firmware CHC (Open China), I believing same is the problem in BRI (Taiwanese) Firmware as well. Flash yourn phone with latest TGY ) Hong Kong firmware and it will be fine.

Thanks a lot for your response. This seems logical as you have correctly identified BRI and all
I am keen on flashing it with TGY Firmware. But before that, I would like to know the possible implications of doing that. And then I would like to know the process if you don't mind please

No problems you will face, not even Knox will trip and void your warranty. Download official TGY from Samfirmware.com and flash it through odin.
Also TGY is a kind of international version like firmware. You'll love it.

I am not a tech-savvy person
What's the difference in TGY and BRI? What would I love about TGY?
And how do I change the firmware. There are not enough tutorials on YouTube

Question S908N KTC to KOO

Hello fellows
So my issue is a bit long so sorry for that
I got this phone 3 days ago
S908N KTC Unlocked ( I live in Middle East and the SIM is working just fine )
I didn't know that this was a branded phone from KTC, I thought it was unbranded KOO
So right now I want to change the firmware to KOO to get rid of the KTC Boot animation and the KTC bloatware/settings
So how should I do that ? Just flash the KOO firmware using Odin? do I need to change csc? is that risky and may trigger Knox and block the phone ?
and after that can I just flash like the middle east firmware ?
Thank you in advance and sorry for taking too long
I'm attaching a screenshot of the CSC and software version of service provider

Use samkey. Pay for a key then change your csc using it

Yes, but some users already tried and it worked. I remember reading one or two days ago about exactly this...it says it is not supported but it works. I recall it was an Exynos device not SnapDragon but should work the same

Hi, have you managed to change the CSC?
I also have the s908N and want to maybe put a European CSC. Also have no idea how does that work with SAMKEY

Thanks for confirming
At least it appears possible to root it and maybe install a custom rom.
I assume that only the rom builders might be able to create a solution for the N version as an installation option in a rom.
However they might not be motivated due to the small number of people having the N versions. Unless of course a few of us agree to contribute in the form of a donation, then maybe a developer can play around and make it happen. What do you think?

well, I'm not really planning to root as this will trip knox.

Any news on changing KTC to KOO? I rooted SM-S908N, installed app Phone INFO+ Samsung, but don't see a way to change CSC. It just sees KTC region. Chimera Tool also gives info SM-S908N is not supported device. So, is there any way to get KOO or at least get rid of KTC Boot animation and the KTC bloatware/settings?

any update, bro?

Sadly it seems like the Korean version of the phone will never get a different CSC... :/

I successfully changed KTC to KOO using Shell exploit method mentioned in S22 thread.
Also, yeah without root and without triggering knox.

Question Flip 3 5G F711U1; XAA => INU

I have got a Samsung Flip3 US unlocked version. Have been using it outside US with and Indian SIM card from last few months without any hiccups. With Samsung Pay working as well.
Now, with the release of 5G services here in India, I'm not sure the bands that Indian operators use are unlocked or not in this. Jio (Indian service provider) says that you're using a non-5G device.
So, I was wondering if I flash an INU firmware to my device. Will it unlock the bands and also let me get OTAs from Samsung? Maybe if someone here did this already?
(According to Jio, this phone is compatible with their 5G network. Also, checked on gsmarena, the international version has the bands that JIO supports.) Since the chipset in international and US is same, I suppose the bands are already there in the device.
Thanks in advance for your help and comments.

Hi Jatin, I don't think flashing your US flip 3 with IND firmware, will fix your problem. The IND firmware is for the F711B model, you are on the F711U1 model. I would not try that. A lot of the F7711B firmware are multi-CSC, but not for the U1 model.

Thanks for the reply, @slysurfer.
I was thinking that since both F711B and F711U1 share the same chipset (Snapdragon 888), the F711B firmware drivers will work on F711U1.
I read some other posts in here (on XDA itself) in which someone with an EUX variant flashed INU firmware to it. Not sure the EUX variant is multi-CSC or not.

Yes, the EUX variant is multi-CSC (to a degree) I can flash any firmware from Europe to South East Asia, but as mentioned we can't flash any firmware from US/Canada.

Big >IF< you can OEM unlock the bootloader you can install twrp and disable the vbmeta and flash a U firmware over a U1 phone and visa versa. But even if you can do all of that it probably still won't work. Personally I'd take it to my local mobile phone stall and see if they can do it.

Thankyou @beanbean50 for your answers.
Sorry for the noob question, . Earlier when Samsung used to release 2 different hardware versions of the same phone like one with Exynos and other with Snapdragon, flashing the other region ROM was not possible.
So, I was just wondering, since both the regions (US & South East Asia) has the exactly same hardware, the networks bands in both of these must only be software locked. Thus, since the US version already has the hardware, can't simply flashing a different region ROM should work.
Again, if there are some other locks that prevent this, it's not possible to flash. Just like if on paper both devices are same, the only difference they have is, they are released in different region.
Also, I checked, both are also manufactured in the Vietnam.

Can you unlock the bootloader?

There is not OEM unlocking in under developer options. I have through other posts and things on how to unlock. I suppose it can't be unlocked in a straightforward like F711B can be.
I suppose this is the hard-stop that cleared my doubts.
Thanks one again, @beanbean50 for your time and answers. Really appreciated!!
P.S.: If you or someone you know have some experience unlocking a US snapdragon Samsung device bootloader, please do share. I might have to consider unlocking bootloader in the future.
