Hi there
I have a factory unlocked Samsung S8 (never been locked to any network) that I took on holiday to the US recently and got a T-Mobile simcard for a few weeks. With the simcard in T-Mobile software and a T-mobile startup and shutdown animations were added to the phone.
I'm now back in the UK using my UK simcard but the T-mobile branding still remains. Does anyone have any idea how to remove this?
The CSC appears to be set to TMB. All the guides I have read about changing the CSC talk about either rooting/flashing the phone, or factory resetting the phone. But this does not seem right as it was changed to TMB without either of these taking place. So surely there is a way to change it back as easily?
(CSC change via #272# or #24320855# does not work).
Any idea how to change this easily?
Thanks

Hi all,
I bought an S5 that had been locked to Vodafone. I have had it unlocked and flashed it with the UK generic software to remove all of the Voda bloatware. This is all fine but unfortunately it still has the Vodafone WiFi settings in it meaning every time I am on the underground it tries to connect to the WiFi under Vodafone, when I have looked there is no option to forget (remove) the Vodafone settings. I flashed the phone using Odin and followed the guide and used the firmware supplied by Sammobile.
Any help would be greatly appreciated.
Thanks,
Matt
Hi. I have an unlocked Vodafone one I picked up today. Can I ask what CSC you flashed in Odin and died it trip Knox?
Flashing firmware doesn't routinely remove userdata settings. Do a factory data reset from the settings menu and that should resolve your issue. Be sure to backup any files that are important to you first though.
In the alternative, you might be able to reset just the wifi settings by going to the Application mamager in the settings menu and see if you can identify which is the wifi app. If you can, then clear cache and data from the tab for the wifi app.

Flashed mine with BTU tonight. It didn't stick properly the first time and using an app called Phone Info, it said the active CSC was VOD/BTU. I need to factory reset and reflash a few times before it fully applied the new CSC.
Maybe yours is VOD/BTU?
Hi
I have searched the forum beforehand and can't find a post with the same symptoms so...
I have just bought an S5 which will not make or receive calls or texts, although my mobile data works fine!
The guy I bought it from said he had it brand new and sealed, and used a Giff Gaff card for a few hours with no problems before the issue developed. I'm using Virgin. It was apparently from new, a Three network phone but did not appear to be locked to their network.... no unlock messages appeared when my SIM was inserted, it all appeared to work until I tried dialling!
I get a good signal and all the indicators are that the system is connected and functional, but when I dial any number the phone dials briefly then shows "Call ended". Texts just fail after a short while. Emergency calls work OK so the radio seems fine.
From the wonderful Phone Info app the following are installed:
Bootloader version: G900FXXU1BNL9
Baseband version: G900FXXU1BNL9
PDA version G900FXXU1BNL9
CSC version G900FH3G1BNL1
Product code: SM-G900FZBAH3G
I have tried the BOB7 BTU firmware via Odin and this worked ok but didn't fix the problem.
I also tried to downgrade to 4.4.2 with both the Three firmware and the ANG2 BTU firmware. Both just cause the phone to hang at the splash screen.
The serial number, IMEI number and the "refurbishment" check all show the phone as genuine.
Knox is still sitting nicely at 0x0.
Looking through the service menu settings nothing obviously jumps out as a problem but it does seem to be some sort of SIM lock.
Phone info shows the manufacturing date as 2015.01.03 so should be in warranty so I'm holding off rooting it as long as possible
I have scoured the internet and found a couple of others with the same problem but no helpful replies to their queries.
Any ideas anyone? Thanks guys
Try a Giff Gaff SIM in it, if that works, you have your answer
If you have upgraded from 4.4 to 5.09 through Odin as I did with mine which is Generic BTU the phone calls and texts would not work after the update so I did a factory reset then flashed the BTU firmware again did another factory reset and the phone has been fine ever since.
One of my friends got an S5 just before Christmas on 3 Network he was told by them that they no longer sim lock their phones how true this is I don't know but he tells me that's what the sales person told him, but he now has Generic BTU firmware on it not the original 3 firmware, he had to do a factory reset twice before his worked properly
So it may be worth trying bt flashing the BTU firmware again (BOB7) then doing a factory rest, flash the firmware again after that and factory reset once more then see if it works properly
Thanks for the quick replies.
I have flashed the BOB7 and BNL9 firmware several times with factory resets... no difference. I have also tried to downgrade from the original 5.0 to 4.4.2 (UK S5 didn't get 4.4.4 as far as I'm aware) but the phone hangs on the splash screen and I then can't boot into recovery.
I am waiting for a Giff Gaff SIM to try but tried my mate's contract Three SIM yesterday and again data was usable but no phone or texting. In fact it was worse than the Virgin SIM as it displayed no network whereas the all the Virgin info was there as it would be on a working phone.
I originally thought it was a faulty radio but as emergency calls work I have ruled this out.
One thing I've noticed is that in the Service menus there is sometimes the message to "Pease reboot" - an obvious typo but not something I would have thought Samsung would have overlooked. Maybe it's a dodgy clone. Anyway of knowing for sure?
One other thing that may or may not be relevant. In my working phones with the Virgin SIM, the Service menu shows the "Speech Ver" as "FR FR FR" as does the dodgy S5 when it has the Three SIM in it. When I put the Virgin SIM in the phone the "Speech Ver" changes to "AMR, EFR, FR". The "FR" I believe means "Full Range" so is that a contributing factor?
I've attached a screenshot of the phone menu with the Three SIM inserted.
Thanks for your help so far guys, it's much appreciated, this has me stumped.

Thanks for that mate, mine compares ok with yours, particularly the "About" status.
I have now tried 02, Three and Giff Gaff sims as well as my Virgin sim. Same problem, can use mobile data but no calls or texts.
reflashed 3 more times with a factory reset after each, same problem.
so recently I bought an unlocked galaxy J3 without a contract. I used different carriers before going on a trip to another country. the phone did not work there and said network locked. I thought it might be country locked but when I came and inserted my original sim which was working before it still displays the same message. i tried factory resetting it without any luck
At some point after an update I noticed I couldn't use region specific apps like Galaxy Apps, Bixby Voice etc. (SM-G950U1 unlocked phone purchased and used in USA) I have been trying to find a solution for a long time now to no avail. However, I believe I managed to narrow down the problem to my csc code being gcf instead of xaa. I have been trying to revert my csc code to XAA several times now (recovery reset, Odin, using a Sprint sim etc.) Any tips?
Changing CSC code to the original one
UPDATE: I managed to solve the problem on my own despite being on call with Sprint support for hours on end to no avail. Basically, my problem was the following: I was using FreedomPop (VoIP number on a sim card). When I did a software update, my phone's CSC changed to GCF (which stands as unknown). I got a new sim card eventually (one from Sprint). However, I couldn't get it to activate and work on my phone. For others, the phone was rebooting after inserting the sim card and switching to SPR CSC whereas mine wasn't doing anything. I ended up using the Carrier Switch for Snapdragon guide (do a lot of reading beforehand). It ended up working out beautifully. I inserted the sim card, phone got activated and I was able to use all the apps I mentioned in the OP and get updates.

So i finally got through. What i did was root my phone then use the Samsung phone info app to change the csc (must be rooted to do this). after changing the csc i flashed back to stock rom and all is well.

Sorry, been super busy this week. I was also on bootloader ver. 2. I'm glad you solved it though!
Hey team,
I have an SM-A205U that apparently was flashed for Sprint or Boost. I put a Spectrum (MVNO) sim in the phone and it works, but I can't get rid of the Sprint device registration failure notification. I think I saw during bootloader that it lists BST as provider.
I haven't been able to figure out how to get rid of that Sprint branding. It also shows up in "About Phone".
Which firmware do I need to load to get rid of it? I looked at sammobile, but don't know which one I need to download to have a brand-free firmware.
Any thoughts?
Do *#272*yourimei# and change csc to xaa and it will reboot and branding will be removed
