My phone ain't accepting sim cards anymore so I have to send it back through to T-Mobile UK, does anyone know if I will have to flash back the original t-mobile firmware or should I just leave it?
I have downloaded the Cetus T-Mobile firmware just in case which should suffice I think.

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.

To get rid of carrier branding, you will need to flash unlocked stock rom using ODIN. Germany(csc=DBT) rom is the best for the SM-N910F. It will get rid of all bloatwares and carrier branding.
You can download the ROM from this thread: http://forum.xda-developers.com/not...ermany-dbt-t3029508/post59616447#post59616447
Hi,don't know how the previous owner unlocked this phone but when I send email etc it says I'm on 02 ? I'm on T-Mobile & the sim does work no problem,the rom your saying Germany ?? Would I not be better of with a T-Mobile stock or will that fill it with bloatware as well ?
I want to do something along these lines
I had an O2 Note 4, unlocked with a code and an EE SIM. Running on the German BTU Lollipop. Now though I'd like to flash it via Odin with the stock 4.4 EE ROM. Is this possible? Currently I have tried to do it but I get "volume size too big 245760 < 512000" when I try to flash it from Odin.
My basic question though is: can I effectively change my O2 UK supplied Note 4 ROM with the EE one. I want to use the EE tap and pay app with my shiny new EE NFC SIM and this doesn't appear to be allowed unless I'm on an EE ROM, in the future I'd also like to use EE wifi calling when that is released for Note 4 via (presumably) the EE Note 4 Lollipop update too.
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.
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
I just bought the Verizon s7 edge at best buy for a good deal. However I am a tmobile customer. The people at tmobile were unable to get the phone to work with tmobile. So I went back to best buy to get my money back. The guy at best buy laughed.. he inserted the Sims card created a tmobile access in the settings and now it works with tmobile..cool...but...everyone my phone restarts I get the msg the Sims is not a Verizon sims..
Could I use Odin and flash the tmobile firmware and my phone still work? And recieve tmobile ota''s?
Mine does it to with att I just swipe it away because it dont effect anything
I don't know if you can flash a t mobile firmware, but you can flash a G935U firmware, once you flash U firmware you'll get noticed that all Verizon junk will gone, including that ****ing notification of Verizon SIM..
PD: I have a S7 Edge (G935V) with G935U firmware using a Mexican Carrier, BTW sorry for my bad english
Thanks for the help guys.. I guess I will just try and see once the official nugut comes out..
I will flash the T-Mobile and see what happens..
Worst I would have to do is reflash the official Verizon back on it..
