Switching country. Should I switch to local CSC firmware? - Samsung Galaxy S8 Questions and Answers

I'm moving to Germany from South America. Besides the fact that lastest version available here is still CRC7 (eye-roll) Would it be a good idea to flash German unlocked firmware, or is it exactly the same? (perhaps the modem is optimised for the local bands?)

"Past-switcher" here. I ended up flashing the German-version of the Oreo update when they were the first to get it. I didn't notice any difference with my UK-based S8 (Exynos).
I think unless you actually have any issues, i wouldn't bother flashing. Logically, if your phone supports the bands, it will work fine.

[Q] Can I flash UK firmware on my canadian GS5?

I bought my GS5 from Canada which means it's set on canadian LTE bands, now I'm trying to use my phone in UK and it doesn't connect to data network, not even HSPA so I was thinking that flashing a UK firmware might solve the problem because I read somewhere that since GS5 runs on Qualcomm its hardware supports all LTE bands by default but I am still afraid that the wrong firmware might brick my device. Can anyone please confirm that information. thx a lot
As long as that firmware is supported by your specific GS5 model this should not be a problem.
I live in South Africa and have flashed many stock firmwares from different countries.
Just a note... you might not have to reflash the entire ROM but merely flash a supported modem/change the csc. Changin the csc does however factory reset your phone.
Yes but a different csc file from the stock rom version will prevent the phone from receiving ota update. Anyway it's not my phone so I won't take any risks and the owner seems to be fine with hspa connection.
Search sammobile.com for the phone model and stock firmware from UK. Just flash that and then you won't have to change the csc

What happens if I flashed another country firmware??

Suppose in the case I bricked my phone and I don't know the baseband version of it. Now what is the option to recover? Flash stock firmware via Odin but don't know the baseband??? What will happens if I flash another country stock firmware?? Will the phone hard brick?? Or it will work fine?? Thank you
The worst case is that your sim card will not work with that software. This is only if your phone is carrier locked.
If it is unlocked, or neverlocked as others put it, then you can flash any firmware you like, as long as it is for your respective phone model.

Make sure that this phone isn't locked to O2 or any UK carrier.

You should flash Nepal firmware then. It would give you better (more match) CSC code. The CSC (Consumer Software Customization) code contains the info about software packages specific to a particular region, carrier branding and also APN (Access Point Name) settings for data connection.
In my case, my S4 i9500 was made in Vietnam and when I received it, it had a Thailand firmware on it. It is a network unlocked phone. I live in USA. The first lollipop firmware came out was for Russia. So I flahsed the Russian firmware. My CSC showed that it is a russian phone. I used that phone on AT&T network that available in USA, China and Korea, and I had no problem.
Nothing will happen.
@sway8966
Are you really to suggest him to flash Nepali firmware on UK phone? I'll unlock it (the carrier-lock) first and then flash other countries' firmware if need.

Sorry to bump this up but im having problems with my s6 edge (Maybe because of this).
I recently acquired a phone from a relative from UK. The OS is android 7.0 and the carrier is three.co.uk (H3G), we have reset the phone to its factory settings and accidentally didnt noticed that it do auto update on the OS, then this bootloops starts to occur.
The phone isnt network-locked because the phone can receive signals, messages and phone calls on local sim.
Now upon browsing around SamMobile, There is an available Firmware for this mobile and even the firmware which is available to Philippines but only ver. 6.0.1
Is this possible to use the PH one or still i go to UK(h3g)?
help please
once i take the firmware from other countries and then i install to my phone,
does my phone will going to operate that firmware even if it come from another country
because i tried to find firmware according to my respective country unfortunately i missed it.
so please i need your assistance ..please

Buying a carrier-branded S8 from another European country

Hello all,
So I'm tempted to buy a Tim-branded S8 on Amazon.it because it's crazy cheap currently. I'm not in Italy but from what I've gathered online (and confirmed by a review on the product's page on Amazon), branding in Italy doesn't mean sim-locking so it should be usable with my local carrier. I'm in Europe anyway.
The only major difference with an unlocked phone (since it doesn't seem to have any hardware trace of the carrier) will be the software : potential TIM-related bloatware, delays for updates, etc.
My question would be : could it be possible to flash an official "clean" image, without affecting the phone and its warranty ? If so, which reference should I use ?
Thank you very much !
Yes, was going to ask if it was also sim locked.?
What county are you in and what sim do you use?
Out the box, if sim unlocked, it will work anyway.
Unless you want any advanced features.
Fw wise it's not a problem. I went the other way though, flashing EE ( UK) firmware into an unbranded unlocked BTU version to get VoLTE to work. It caused no issues.
Belgium but I guess European models pretty much have all bands available across Europe...
Thanks for the feedback !
I have the tim s8 here in the UK, flashed the h3g firmware and have WiFi calling and volte functioning without issue.

hi
Im also interested in buying a tim branded phone (https://www.amazon.it/gp/product/B071RSVYSH/ref=ox_sc_act_title_1?smid=A11IL2PNWYJU7H&psc=1) and was hoping if someone who has one could answer me couple of questions.
1) Does the phone have universal warranty? I mean if something was wrong with it and it needed any repair, could I just take it to a local Samsung store?
2) The model number on amazon site is G950, is that different from G950F? i couldn't find any reliable info on this..
Thanks in advance!
If the phone is designed for the European market then warranty applies regardless where you are (within Europe).
All European models are F-models.
You can flash an unbranded ROM through Odin to get rid of any branding which does not trigger Knox.

International Firmware

Before I start, this is the first android phone I've ever owned so the question may or may not be stupid.
So I live in India and I saw the trade-in deal for the S8. I was in need of an upgrade (iPhone 6) so I went for it as I was heading to the U.S soon. I heard that the international version gets updates sooner than the unlocked U.S version. Can I just change my firmware to international, get earlier updates with no drawback? If yes then why have I not seen a lot on this?
Pretty sure the firmware is locked to the device unless you root. I had an unlocked international S6(920?F) . It updated a lot earlier than the W released in Canada.

If the device you get is G950F (international) then updates will come sooner. If you get any other version they are for specific regions, so if you get G950U (US unlocked) you can't flash international firmware to it. Can only flash firmware for the model you get.

Then what are the benefits of people switching carriers for example? There seem to be a bunch of threads giving a tutorial on how to change firmware to different carries e.g. From a T Mobile to Unlocked.

For stuff like WiFi calling, voLTE, removal of bloat some csc tweaks
Guess that's unfortunate.

exact same model number, different regions, different android versions

it appears the AUS tab a 8 "SM-T350" stopped receiving updates at March 17th 2017 QA1 6.0.1 while 3 other regions got updated to 7.1.1 QJ1 October 15th and 16th.
I have already seen this thread https://forum.xda-developers.com/galaxy-tab-a/help/stuck-flashing-region-restart-t3683613 and I am wondering if flashing, for example, the U.S. version (cellular south) on the Australia model (with exact same model number) would be prohibited in Odin or if it does actually flash, what's the likelihood that the bootloader would be inoperable / bricked?
in my experiences, attempting to flash an incorrect (wrong model or old version) bootloader, Odin just errors. but in this case I don't see any reason Odin would refuse to do it
looking for answers from experienced people, not someone just looking to increase post count
The ROM from different regions will normally flash without a problem. The difference is usually the available wifi channels and the regional locks on apps like Netflix. It is typical for Samsung to release updates by region and if it is a major one, I will usually flash the first region released. Of course I'm talking about Wifi only tablets. Cell phone tablets, because of the differing techs, are another matter.
As long as it's wifi model, region doesn't matter. All wifi tablets sold worldwide actually are the same tablets, so it doesn't matter which firmware you're flashing to it.
However, if you flash US firmware to an Australia tablet, it will only be recognized by Samsung server as an US tablet and follow new updates of US tablet.
Like my SM-T580, SM-P580, when Nougat is available in German or Korea, I did not hesitate to flash the new firmware. When Nougat is available in US, I flash back the US version.
For the purpose of bypass FRP, I am willing to flash Hongkong, Afghanistan firmware if it works with a certain method to unlock FRP ( Factory Reset Protection). After that, I am going to flash back
the latest US's firmware.
In short, you're free to flash whatever firmware you like to a wifi tablet. LTE tablet is a different story as bootloader is locked.
