no WCDMA - Samsung Galaxy S7 Questions and Answers

Hello everyone,
I'm facing a problem with my galaxy s7 when I lock it into WCDMA only I got no network at all , but it works fine on 2G and 4G .
I flashed it with different firmwares but no solution .
Currently I'm using the original firmware

What model is the phone and where are you located?
As the international model (F/FD) and US models (V/T/P) have a different modem and only the US models can access certain radio networks in the US, and I don't believe US model phones have full band coverage outside the US.
So if you're using the international model in the US, or a US model outside of the US you will have coverage issues.

thank you .

Was it locally purchased or imported? Might need the CSC for your carrier https://forum.xda-developers.com/galaxy-s7/development/utility-flashable-csc-selection-30-t3392949

actually it's imported, i took it to different repair shop but no luck

Have you tried flashing with Odin using all 4 files (BL,AP,CP,CSC) that match your country and carrier?

Flashing 920F(france) firmaware on 920i(indian) model

One way to find out...flash it.

Technically, it should matter because of the different hardware.
In Brazil, the model sold is the same 920i - which by the way doesn't stand for Indian.
I know people who have installed the Xtrestolite 2.0 which is 5.1.1 for F and T models. The only things that happened is that they can't use the fingerprint scanner or connect to LTE...

Use Firmware Of A Different Model

Hi,
I have a S8+ with the model SM-G955FD and was wondering if I am able to download the firmware for the model SM-G955F?
The phone was purchased outside of Australia and doesn't use the Australian (Telstra) firmware that I would like it to. I just figured they are the same phone just different model numbers so there shouldn't be any issues right? I might just lose a couple features or something but the phone should work correctly?
Thanks in advance.
Yea, the G955FD is the dual SIM Exynos variant, right?
I'm sure the dual SIM uses the same firmware as the single SIM, so you should have no worries flashing Aussie firmware.
But I would suggest you flash the XSA (Aussie unbranded) firmware, not Telstra firmware. You'll lose nothing, but you'll get faster updates.

The phone will work pretty much fine provided
1 - Exact Same hardware . you can use snapdaragon ROMs on Snapdragon Devices and vice versa for Exynos .
2 - Same network Bands supported . The ROM contains the programs on how to operate in different frequencey bands .

Hi there I am a silly person who purchased a Galaxy S8+ from Kogan which is flashed with Emirates firmware
Its model SM-G9f55FD G955Fxxu1AQL5
No VOlte and Samsung pay etc
I need to use Telstra network (im rural but in a VOLTE area) and so I need to flash it with Australian Firmware so it gets all the local features.
I would just like to know how I know what chipset to use - I dont think its snapdragon
And where to get the firmware.

Here's the XSA (Australia) firmware:
http://updato.com/firmware-archive-select-model?record=0C53FCC1D0CA11E7A5F9FA163EE8F90B
Flash it. Doesn't matter if your device is G955F or FD, the ROMs are exactly the same.
Does the method works with G955J SCV35 model? I'm running NTDocomo firmware on KDDI model to unlock network (single SIM) . I wan't to flash unlocked U firmware but getting scared that the phone will be bricked.

Flashing Another Model's Modem ?

Hey Guys!
So I have just gotten an S7 (930S) and apparently, there is a mismatch between the bands present in the phone and the one offered by my network. I would like to know if I flash 930F modem on my phone would that be ok or not? I just want to flash the modem as well as the CSC of the 930F model. I hope someone can take the timeout to reply to my query.
Thanks

Yes you can, hardware is the same. However when you talk about network bands I assume your talking about the difference between networks using GSM and networks using CDMA? In which case you need to flash firmware which uses CDMA radios.

Well, when I am talking about Bands I am talking about the frequencies in which they operate. For example, my network offers the UMTS 900 frequency, but that frequency is missing from my current modem.
Therefore, I am assuming that if I flash the 930F model's modem, which does supoort the UMTS 900 frequency, I will be able to operate on the UMTS 900 frequency. Can you confirm me on that?
Or will I have to flash the 930F firmware on my phone to operate on the UMTS 900 frequency?
Sent from my SM-G935F using Tapatalk
Yes 930F will work and install the radios you require.
The problem I am facing right now is that although the modem (Shannon335) on my phone (G930S - Korean) is the same as that on the international model (930F). But my phone (G930S) does not support one of the bands that my network supports which is UMTS 900 and that band is supported on the international version , although hardware wise (both are Shannon335) they are both the same.
So, I was thinking if i change my modem, currently its a South Korean modem and flash the international version modem could it work and make the band work for me?

Thank You very much.
I would also like to know how should I choose and which modem to flash on my phone. Which things should I match and what to avoid during the flashing process. I have currently U1 security level modem, so when I flash another modem should it be U1 level as well?

To avoid problems you must match the modem to the version of firmware you are using, so yes U1 to U1. Flash the modem separately via Odin

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 was unlocked

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.

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%.

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.

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.
