Does CSC region matter? - Samsung Galaxy S8 Questions and Answers

I rooted my phone with super su, it did not go so well, tried twrp, to use magisk, but will not work as remnants of the super SU root are still in place.
I am going to flash back to stock firm ware, I purchased my phone out right on amazon from italy, so it has Vodafone italy apps on it.
My question is when i re flash the stock, does it have to be Vodafone Italy for the region or can i use the uk one for 3? AS that is who my carrier is, part of me wanting to root was to get rid of all the italian vodafone stuff off my phone?
Thanks

[Q] Unbranded SGS v T-Mobile (UK) Branded SGS

Obviously, there are differences with the stock rom that will come with either version. However, as I am planning to flash around a bit, this won't matter.
However I've heard that on a branded device, if I flash a different rom then accept an OTA update it will simlock my phone. Is this correct? If so, then will getting an unbranded device be better?
Thanks.
Let's also assume the T-Mobile phone is initially locked and I have to purchase a code to unlock it.
Bump - would really like to get a response on this matter.
I don't know the answer to your question, but my Galaxy is from T mobile and is unbranded and unlocked out of the box.
My SGS is from T-Mobile UK, but I can't really answer your question either.
I can say that the device is both externally and internally unbranded (I can't say about SIM locks, but I assume it has one). No splash screens, no "Web'n'Walk" Internet icon. The firmware supplied is:
PDA: I9000XXJF4
PHONE: I9000XXJF3
CSC: I9000TMUJE6
Only the CSC is custom, I'm guessing just because it comes set up with the T-Mobile APN settings etc.
What I'm interested in is whether, if I made a nandroid backup, what base ROM I'd need to return to the phone to stock.. JF3 is the only one available it seems.
I've just bought a T-Mobile UK SGS on ebay, brand new, still sealed, it was an 'unwanted upgrade'.
I can confirm there is no branding that I've found so far, and there is no sim lock (I'm using it on O2, everything working fine right out the box), I don't know if this is the same for all the SGS that T-Mobile are selling.
another one - even the box was unbranded.
No W'n'W application as I was expecting even!
Completely unlocked.

Fimware query

Hi guys,
I am considering Buying what of these phones as the idea of a joypad for a mobile is awesome, just got one question:
I'll be buying this imported (as its way cheaper) so more then likely it will have Hong Kong (Asia) firmware on it..is there "stock Rom" for this? i had a HTC desire HD that i managed to get back to worldwide firmware myself (after 2 weeks of research) so I was wondering if the same thing is possible with the Xperia play?
I don't wanna buy one and be stuck on another counties firmware.
any tips/help would be awesome
Thanks guys

You should be able to flash the UK generic firmware on it using flash tool. After that you could root it using Gingerbreak, update it to 2.3.3 and remove the bloat.
All without unlocking your boot loader, too. Unless you just want to, that is.

I'm looking moreso towards an aussie firmware, since my mobile provider would be a 3rd party of optus, I dont mind having optus bloatware on there. if theres aussie genric firmware, i would more then happy to have that over a worldwide firmware?

I don't know of an Australian FW, but there could be one. Most go for the UK generic because of being able to root then update to 2.3.3 without losing root. You'll need to unless you plan on installing everything on the SD card.

im not too fussed about it being unlocked...i jsut want a firmware i can easily upgrade ( offical is what im looking for) that supports OTA updates too. its not really breaking any laws if its still the offical firmware suited for the device...any clue where i should start looking for rom guides and files? best to be prepared for when i get the phone!
I would just go with the uk generic. So far when it has come to updates the uk firmware has been one of the first to get the updates.
If you got an aussie firmware with optus bloatware on you would have to wait till optus ok's the update before you get it (god knows how long that would take?). Alot of people got the update weeks later because they had carrier branded software vs people who just have the generic software.
People from usa have even flashed the uk firmware (to get updates quicker) and there has not been any problems. If your phone is sim free it will not make a difference which software is on it.
Follow the steps here to get the uk generic + root with a locked bootloader. Once you have flashed the uk firmware all your future updates will automatically come from the uk.

[Q] Do I need to unlock to use BTU firmware?

I recently purchased a Galaxy S4 i9505 on EE from Carphone Warehouse, and flashed the 5.0.1 BTU firmware. After I did that I then read I'd need to be carrier unlocked, but I tried calling and receiving calls and messages and using 4g and it worked fine. I also saw some posts about flashing modems. Anyway I'm really confused about what I need to do; should I try and unlock or not. Thanks everyone for your help.
The BTU firmware has no carrier branding, which means it has no carrier logos or bloatware included in it. Other than the lack of carrier doodads, it's the same firmware. You shouldn't need to flash a modem as you already have the latest, from when you installed the BTU ROM. However, the S4 would need to be unlocked for use on any carrier if your SIM isn't an EE SIM. But, you either have an EE SIM, in which case you don't need to worry about it, or the S4 was unlocked by the store that sold it, in which case you don't need to worry about it.
TL;DR: Don't touch the ROM. Don't worry too much about the SIM because you can make calls and use data. You don't need to flash a modem.

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.

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

Understanding flashing

Hi guys,
Just bought a galaxy s5 from my uncle who worked in Canada, the phone was locked to Telus Canada I unlocked it through unlockBase which was superfast and easy.. I have now really started using this phone and have now realised that the date format is different to what I usually use, I have done some research and found that an update stopped the ability to change it to prevent blackmarket sales or whatever.. I was thinking can I just flash a uk rom on the phone or not? But will it relock the phone? Also will rooting the phone enable me to change it? Although I don't wanna root because my online banking app won't work or WhatsApp?
Thanks in advance guys

This is definitely one of the strangest reasons for rooting...
But since it's a Telus phone its definitely a G900W8. You can cross flash all and only G900w8 firmwares so i.e. you can flash Rogers on bell, wind on telus, sasktel on koodo, etc

Thanks for the reply, yes rooting was the last option as some apps won't work.. so if i was to flash it i would only be able to use telus firmware which is US could I flash a UK firmware on it? And if I was to flash it would it still stay unlocked or will it need reunlocking?
EDIT: done some more research.. will changing the csc code on my phone to one of a uk firmware, then installing a uk firmware work?

Nope because anything outside of Canada uses a completely different phone model and flashing between different models will likely lead to a bricked phone (phone is damaged unrecoverable)
