Hi guys, just a generic question. What does it mean when the phone is unlocked? I got an unlocked Galaxy S III I9300 and I'm using it on US T-Mobile. Curiously, the phone came with a lot of German T-Mobile bloatware. Are all I9300 not the same? Is it possible to make it completely carrier free? Please enlighten me
It means its not locked to a network .
Branded means its branded by a carrier/network.provider .
Flashing stock rom will remove the branding .

Thanks for the info. Is there a way to update to the stock rom officially through kies or something? And I'm just wondering, are there any carriers in Europe that use stock rom?
Thanks

If you do it through KIES, it will keep all the branding, because it will update the ROM for the same CSC (operator-specific firmware) you have.
You need to first install, using Odin or MobileODIN, an unbranded firmware. All countries have branded and unbranded firmwares.
For instance, an UK unbranded ROM can be downloaded like this:

There are unbranded ROMs for all European countries. Use CheckFus to figure out what their CSC code is.
Thanks. So after i flash an unbranded firmware i can get the unbranded rom updates? And it won't wipe my phone right. Does samsung sell the I9300 with unbranded firmware and rom anywhere in Europe? Personally got mine on Amazon.

- It won't wipe your phone, UNLESS you tell it to.
- There aren't that many OTA updates anyway, so don't worry about it. Besides, when an update is released, you can install it on your phone using the Odin or MobileOdin methods long before it is available on the OTA. None of these require you to wipe your phone.
to use Odin you don't need root, but you do if you want to use mobileOdin.
I've flashed over 20 stock unbranded ROMs on my S III and I never did a data wipe on it, and yet it works flawlessly.
Using the top-right panel of CheckFus, you can download ANY CSC you want as long as it is for the GT-I9300. You don't have to keep it locked to a specific CSC. For Germany I believe the unbranded CSC is coded DBT (or something like that).
Hey, thanks for the info. The website for Checkfus Downloader isn't working. Do you have a link to it or can you post it here? From what I've read, CHANGING the CSC will wipe the phone right. Is there any reason for me to change the CSC to UK or something? I don't really care if the default language is German as long as I can change it to English. I just want to get rid of the bloatware and get an unbranded firmware/rom.
EDIT: Found the firmware on SamMobile. Thanks for the DBT tip.
http://www.sammobile.com/firmware/?page=8&view=6505
I just want to confirm flashing that won't wipe my phone? Because the CSC is different isn't it?
EDIT 2: Read your post again. So flashing the firmware won't actually change the CSC right. I just won't be able to keep the unbranded rom if I update via KIES?

-Ok, so. Basically I can flash any unbranded firmware I want (UK, German, etc...) regardless of the CSC.
-I just have to use Odin everytime I want to update.
-Also, will I lose the unlock?
-Will there be issues with the modem/baseband/CSC incompatibility or something.
P.S. I keep asking if Odin will wipe my phone because I used to own a Galaxy S 1, and Odin was basically the last resort to flash your phone back to stock, and it was always a wipe.
Thank you.
I have a galaxy s 3 which was given to me as a gift. It was on orange, but was unlocked for me so that I can use it on o2.
I have no idea how it was unlocked, but im unsure about upgrading the software through kies.
Can I still upgrade my software through kies to the latest jellybean? Because ive been waiting for the upgrade on my phone and it still hasnt come up. infact i dont have the option to check for updates either
what shall i do? I dont know if ill lose my data or block my phone by upgrading to jellybean via kies
help please
Your phone maybe unlocked but have the same carrier firmware. You need to flash via Odin a unbranded firmware, as if you do update by kies it may lock your phone again.

Last week I headed over to Sammobile and updated my latin american Samsung Galaxy Mega i9200 to different firmware, (Thailand) But I tried again yesterday with the newly listed firmware from China and it would not flash. Is there any particular reason China Firmware would not work?
Thanks

As long as it was also for the I9200 it should work, have you rooted the device? You may have to unroot and flash it.

No, it's not rooted and it was definitely for the I9200 and I had no problem flashing other firmware, so i thought maybe the China firmware was for a specific carrier? I noticed there is also a new Taiwan firmware, which I will try. There is also a Ukraine one, but along side that one, it mentions a carrier, so I assume that automatically means it wont work. Not sure, but I thought it would be a bad idea to flash one that shows the country & carrier in brackets.

Odin on a pc. I actually forget the error now.. just said FAIL and then i couldn't reboot, so I flashed the firmware I had previously on it to get it going.

Just flashed the Taiwan Firmware that was added today at Sammobile, no problem. Not as current as the China one, (MF3 vs. MF4) but it worked. Must be something I'm missing on the china one.
Hi folks!
Getting my S6 Edge on Monday the 13th.
My phone will be delivered with carrier branding - boot animations and added bloatware.
Since SammMobile released the official firmwares, i wanted to know if any of those firmwares can help me "de-brand" my phone (install stock Samsung rom)
Anyone know what does "Country/Carrier - Unknown" - means?
I cannot post any links yet
I would also be interested in this as my phone has come full of Three bloat ware and boot animations. I would much rather have a stock rom. Plus it does not have the A-Z option in the launcher for apps.

As far as I'm aware you can flash the BTU firmware (stock, no branding) using Odin
Firmware can be obtained from Sammobile
And I've been told this can be done without tripping Knox

This is also a concern - i don't want to trip Knox a this point. Can someone confirm?
Also as i have seen on Sam-mobile, there are a lot or ROMs with different carriers/countries, can someone please explain the difference between them?
Are they "Branded" and come with bloatware or just region-linked?
Because there is also "Unknown" version in that list. Does it means Stock international ROM?
Can confirm I have flashed the UK BTU firmware over three firmware with no issues what so ever. Knox hasn't been tripped and all bloatware has gone. Although still no A-Z sorting of menu.
I really hope we can do this on AT&T without tripping KNOX. I'm sure it would remove all that BS AT&T puts on the phone.
The ATT models have app drawer sorting? It's a stand alone A-Z toggle in the top right of the app drawer
T mobile does
EDIT: Nevermind my previous post at this place. Seems like Sammobile is having troubles and gave me the wrong firmware file (S6 instead of S6 edge). Or I was to tired, that's why Odin said "FAIL"
I just unbranded my s6 edge by flashing the german firmware from sammobile successfully. I accidentially didn't even unencrypt my phone before and it works.
All Data is still there and the apps did update on first start.
Knox not tripped.
has anyone found the USA t mobile firmware for the edge on sam mobile yet? (SM-G925T)
I've only seen it on junk sites like Rapidgator, and Upload.to
thanks

So it doesn't matter which firmware i would flash? (Germany, turkey etc'....)
I haven't seen t mobile edge firmware on sammobile yet; its on rapidgator and upload to, but it will take 8 hours to download..
and I would NOT risk trouble by flashing anything but t mobile usa firmware, but hey, its your phone to do what you want with..
How long do sammobiles downloads take
on a free account, probably 2 hours; less if you pay for a premium account I assume
but as of this am, the t mobile edge version isn't there yet

The firmware must be for your device and it should be made for your region. I can assume that if you flash another one you might have troubles with the mobile phone network.

Flashing official firmwares via ODIN will not trip KNOX. Use SAMMOBILE to download the one you want.
Use also the latest ODIN software version.
Some official firmwares come with some bloat apps but they can be easily uninstalled.

Not entirely true. You can use what region you want. I never had problem with the signal after using different region firmwares.
Hello there.
I have a SM-925I from Brazil, but I realized that this variant exists in other countries... My question is, if I change the original rom for a rom from another country, but from the same model (SM-g925I) will it trip my knox? Will i miss my warranty?
I want to install lollipop 5.1.1
Thank You
If you're going to venture into ROM changing, forget about warranty

Just root and be careful. I've rooted every device I've owned and don't care about warranty. If you're careful then you are good. Checkout ping pong root. It roots without warranty.

The only 5.1.1 version for the 925I are from the Indian version and it seems that Samsung has since held back a little with releasing it for other CSCs.
There have been a few reports of people flashing the 5.1.1 version on their 925I phones on Australia and no longer getting good 4g speeds. I'm going to wait until the Australian version of the update is released.
Having said that, if the firmware you want to flash is stock firmware produced by Samsung and is compatible with your phone variant (I.e a 925I stock firmware) regardless of CSC then flashing it via Odin should not trip Knox and should not interfere with your warranty. A couple of people here or there have stated that they've tried Knox this way but the majority (including me) have been fine.
You'll need to factory reset following changing to a different CSC if you want to receive over the air updates.
My suggestion? Wait for the Brazilian update. As for rooting, apart from blocking ads I've not missed having root at all.

Hey all,
I've done some rooting in the past, so have knowledge but it's limited comparatively to the community. I bought an Unlocked Snapdragon S9+ from Best Buy and the AT&T FirstNet service for first responders only works for AT&T branded devices. I wanted to try and flash an AT&T image on the phone if possible. Is this possible? Can anyone offer some guidance on how to accomplish this?

Yep, you can flash the AT&t firmware onto your unlocked device. You would have to download the firmware and then flash it with Odin, you can check the general section to learn more about this and we here can help you through it.
The other thing I was wondering is that I assume that FirstNet works on the AT&t firmware. Technically your phone will still not be an AT&t phone according to its IMEI number, but firmware-wise it will be just as an AT&t phone after you flash it.

I understand. So get ODIN and the AT&T firmware and just flash? I've done rooting before so familiar with ODIN for the most part, just wasn't sure if I needed a specific firmware version based on having an Unlocked device or not.
And to your wondering thought, FirstNet does work on the AT&T firmware and they WOULD still recognize my phone as an Unlocked device(by IMEI) as per the FirstNet tech support agent I just spoke with. However, I'm hoping that having the firmware would make the device more compatible with the FirstNet service

You just need the latest AT&T firmware that you can find(BRK2 I believe, unless the latest pie firmware has already been posted somewhere), and you will need the patched version of Odin that will allow you to flash a different firmware than your device came with. It seems like AT&t firmwares can be hard to find for some reason but there was this thread which has not been updated I don't think: https://forum.xda-developers.com/ga...ck-official-attoding965usqu3brj5-s9-t3866823. But it looks like that would at least get you over to AT&t firmware and then you could get OTA updates up to current hopefully. You might want to ask in that thread for further instructions on firmware and how to flash everything properly. You would want to use CSC instead of HOME-CSC, to wipe and fully set up the phone, and there is something which I don't know about called USERDATA, which I think might need to be found and flashed also.
