I have a VOD Uk device I flashed to BTU so it was unbranded. With the MM coming out I plugged into smartswitch to change back. All went fine however it selects SIM csc and not VOD as it is a multi csc. Now I can't use wifi calling with this csc. In tried multiple flashes and wiping cache and resets. I've even gone to the XEF rom and back and still get SIM csc when i flash it.
Is there any way of selecting the correct csc or editing the firmware without tripping Knox to just install the VOD csc.
Many thanks for your help.
I would also like to know if this can be done.:good:

I'm hoping there is a bug in smartswitch in relation to the Voda firmware as other country's like Voda Germany are restoring and getting SIM csc as well not the one specified in the restor
Smartswitch won't let me restore either, it give an error saying sm-g920f not compatible :crying:.
any of you folks got anywhere with this issue? I'm still stuck on SIM
Can anyone provide a very detail guide on how to change from Three UK firmware to BTU on Galaxy S8+ as Three UK hasn't updated Galaxy S8+ since April. I feel very left out at the moment. I would like to change without losing data. Is there a way of doing this?

Yeah I hate this too so out of date, but I am seeing three firmware appearing on sammobile everywhere else apart from united kingdom. I was actually thinking of flashing the three firmware at one stage as I'm missing out on volte but having more up to date firmware is top priority for me
I would like to keep WiFi calling. Even though I haven't used it once. Why is Three behaving like this. Did you flash BTU version after being fed up with Three lack of updates.

NOT possible...
BTU is part of the Multi-CSC OXM where MANY European CSC's are included.
If you download for i.e. the BTU-firmware, that'll be the same firmware as for i.e. PHN (Netherlands).
You'll have to flash BL CP AP & CSC_OXM on your phone; your phone will be resetted afterwards.
The DEFAULT CSC for OXM is XEU. Your phone "sees", that an UK-SIM is included and will "switch" to the best CSC for your device, which is in this case XEU. You won't get BTU on your device...
I'll lose my data with XEU won't I

If you change your CSC, you'll ALWAYS lose your data...
Also worth noting that to keep Volte/WiFi Calling you would need to use the Three Firmware (H3G) as the OXM CSC firmware does not enable it.
I'm a Three UK customer and have tried many times to get Volte/WiFi calling working on XEU (OXM Multi CSC) with no luck. Only works when I use H3G firmware but I hate the crappy branding so sacrificed Volte for no branding.
I flashed from vodafone uk to btu but as someone said you get xeu. Updates are fast I had 3 already.

I flashed the OXM firmware from henklbr's thread, but used HOME_CSC from the last H3G firmware to keep WiFi callling

I'm on 3 had update this morning,
Latest update was pushed this morning on 3UK
Good one
flashed three firmware coming from xeu but cant send text messages lol everything else works, also the message center is grayed out so i cant manually imput the smsc number....
Just need to wait until we get August update. Probably won't be till November/ December. I hope when Beta for Android O is released. We will be able to join in on the excitement
Hi,
Has anyone been able to access Three and EE VoLTE on ether XEU or BTU firmwares? I am thinking of getting the S8+ Dual SIM but don't really want to have to flash a 3 branded firmware on a dual SIM model if I can help it.
Thanks.
Can't answer for dual SIM variant, but you can do it in a number of ways, you flash the three firmware and CSC, or you flash the EE firmware and CSC. Both will mean you get OTAs. I however used EE CSC and xeu rest of the firmware. I get the best of both worlds but have to manually update using a hybrid of the EE CSC and xeu rest.
I have flashed BTU firmware before with Three CSC but yes it causes a mismatch and OTA updates no longer work ;-(
I just unboxed my G955FD and put my cricket SIM in and have no response from the network other than pushing an APN and my phone number. I tried manually selecting carrier networks and it listed 5 different "cricket" to attempt to connect to. At one point it showed signal bars in the status area, but no network connectivity. When I automatically connect to the network it responds saying I am registered but no signal bars in status and no activity. I appreciate the help.
Can anyone offer some tips before I call it a lost cause? The phone is out of its return period and probably broken since it will now receive a cricket badge and bars and LTE service but will not make calls or go online
Hey, are you on stock ROM. My 955F works just fine on Cricket, though compared to my daughters AT&T setup, her data is much faster. just discovered this today, and tomorrow will visit Cricket and AT&T to find out why...
Jan 9, 2108 update. I discovered Cricket is limited to about 5-6 Mps. I'm now on AT&T, for a few dollars more for two lines, and can get up to about 40-60 Mps in town.
What region CSC are you using?
---------- Post added at 07:59 AM ---------- Previous post was at 07:35 AM ----------
Here are my apn settings
Name: any but I input Internet or Cricket, I think it will work with whatever you like.
APN: ndo
MMSC: http://mmsc.aiowireless.net
MMSC proxy: proxy.aiowireless.net
multimedia message port: 80
mcc: 310
mnc: 150
apn type: default,mms,fota,hipri,supl
I know when I've setup APs on other phones there have been times that I will first do a 'reset' of my network settings on the phone, then reboot. Sometimes that will help. After that I will enter new APN settings and reboot.
On this 955F, with a viable CSC my phone just finds Cricket and works. With a bad CSC, it may list/show the cricket or AT&T networks, and will not register, no matter what I do, and for how long.
For example, my phone initially had a stock F ROM and a Panama region for the CSC. It worked with Cricket straight away. I changed the CSC to XAA using AT&T, and would find the towers, but would absolutely not register/work.
I ended up installing CarHDROM - a Note 8 OS ported for the 8+, and It took me a bit to find a CSC package that was meant for the ROM (Note 8) I was using, meaning I had to use a Note 8 CSC, even though my phone was an 8+ 955. Once that installed, Cricket started right away.
The CSC that came with CarHDROM I don't think worked straight out, but I can't recall for sure. I did end up using a XAA CSC, for the Note 8, non-AT&Tand that solved my connection issue after I had installed the CarHDROM.
CSC and phone wise, the ROM takes precedent, and the CSC must match the ROM (model). Seems that way to me, anyway.
Hope his helps.
There is another post about a FD phone that won't connect up, as well.

I am on stock ROM. I guess I will root today and change CSC and hopefully that fixes whatever issue is going on. I have seen the cricket badge and LTE bars recently but no registration on network. If not, the eBay seller said they will take the phone back I'd it's indeed broken.
Ok so far no luck changing the CSC on stock ROM. I am going to try a couple different ROM and CSC combos tonight. Once again I am showing bars and cricket badge but not connecting data or voice on the phone, after root, and changing CSCs. I feel like Im so close and passed up my last day to return to eBay seller so I hope it truly is software and not hardware related. Im thinking of going by AT&T to act like a potential customer and see if its cricket messing up. Any other suggestions to try before I go crazy and use this phone for target practice?
Is it possible this is a region lock issue? My phone is a Tawain version and it was brand new out of the box. There is no sticker on it mentioning region lock. Does anyone have any insight into region locking for outside EU devices?

Good question. I have a 930S Chinese region and it pulled in ATT/Cricket/TMobile just fine. I did have problems when I flashed a custom ROM, and flashed the CSC that came with the ROM. Later I flashed back the OEM CSC for the region (China) and it worked perfectly, again.
If you do flash a custom ROM, make sure you get a CSC package that is meant for that ROM (model). Not the exact model of your original phone. If you can find an XAA CSC that is meant for the new ROM, should be perfect.

Ok I have been changing CSC through TWRP with the CSCSelection Utility. Is that what you are referring to with flashing CSC? Is there a more effective way to do this through Odin? I think tomorrow morning I am going to flash back to stock firmware and start over. Am I able to flash any stock firmware for the SM-G955FD through Odin or do I need the original firmware for my region, which is (BRI) I believe I remembered reading I can flash everything for that model, but not any North American firmware meant for the SM-g955U

Just flash the CSC that comes 'stock'/with the rest of the full, stock firmware set, Odin will work. Have the SIM in the phone before you reboot, as for me it seems to help.
I haven't found a difference, for me yet, just flashing the exact CSC through Odin or TWRP. As I'm now on a custom ROM, I'm usually flashing via TWRP with a CSC that is supplied by an Aroma setup. Aroma is very handy.
Yes, flash your full stock via Odin. If you have TWRP you will lose it. You can re-flash TWRP from Odin. I typically flash TWRP all by itself, but I don't think that is really necessary. Maybe someone will come along and let us know.
As an aside I always keep a copy of zips/installs of TWRP, re-verity and SU on my SD card.
So after the stock full flash, I reboot into download mode and Odin flash TWRP, and follow that by a direct 3 key reboot into recovery, and TWRP will load. If you are going to root then flash re-verity, then SU/Magisk. You could then flash your CSC, but with the issues you've been having, I'd then boot to system, do the initial setup of the phone, and then boot back to recovery/TWRP, backup the phone.
Then TWRP flash the CSC Aroma package, making sure you have the SIM in the phone and reboot to system. I've been using XAA as my CSC with my custom ROM, within that is AT&T, T-Mobile, etc for US phones. I select the main XAA CSC from Aroma. Next I select the unbranded XAA as my more specific/local package, instead of AT&T, for example.
My 955F, stock worked just fine on it's 'stock' CSC (China region). I only had to change the CSC when I flashed a custom ROM, and that ROM did not have the ROM's (model) of XAA, so I had to find a CSC, which had XAA, that 'matched' the ROM I had flashed. I had flashed a Note 8 ROM, CarHDROM,v8 initially. Again, that ROM was largely meant for Europe and Exynos phones, so I had to be pointed to a Note 8 CSC that was compatible with the Note 8 custom ROM.
Yes, Odin is where you would flash stock firmware/stock CSC (not in an Aroma package) for your SM-G955FD. It is my understanding that all non-US phones, eg the G955's, are mechanically the same, so flashing 'any' Exynos ROM, G955FD ROM should work via Odin. You can also flash CSC packages via Odin as well, but there is no Aroma process, to my knowledge/experience. So have the specific and correct CSC to flash via Odin, if you go that route. It sounds like you are aware your phone is Exynos? A non-US phone?
I specifically bought my G955 (8+) as non-US so it could take root smoothly/easily, and work great world wide, including working great here in the US. Sometimes the U.S. does not seem a part of the world.
As I've been messing about with S7's/8s, there have been times that the phone did not grab onto AT&T, for example, and i would then 'reset' the network and reboot, with the SIM in the phone, then do a search for phone networks/services. That usually solved it, but when it did not, and I know I have the right CSC, I would then input/create a new APN, with AT&T, Cricket, Sprint, or what-ever service I needed, then reboot.
The only times I've not gotten the phone/s to grab the networks after that is when I've had the incorrect CSC.
Again, on my stock what-ever country G955F, stock G930S, etc, all Exynos, with the same stock (non-US) CSC that come in the firmware package, the phones have grabbed AT&T/T-Mobile just fine. If it would not, I would have reset the network, rebooted and entered the APN, and then rebooted (with the SIM in the phone). Done a network search after that, if necessary.
Hope this helps.
So today I stopped by TMOBILE and the store clerk popped a SIM card in and it fired up 4G LTE immediately and made calls. I then decided to stop by AT&T and it showed bars but refused to register or do anything even with the APN settings being pushed through from AT&T and Cricket. I am finally happy to realize that my phone is not defective (which I had feared before) and that it must be this service area and the bands on the G955FD. I have wanted to switch to TMOBILE for awhile now anyway so this is my chance to have an excuse to do it. Any input on why it won't access AT&T through an AT&T or Cricket SIM? I'm curious now more than anything. It must be missing a band that this area uses correct? The phone is clearly unlocked and functioning correctly.
What local CSC r u using?
Did you have AT&T check the APN?
T-Mobile and AT&T work on S8+ just fine, but need appropriate APNs.
Head back to the AT&T, if you want AT&T, and see if they will reset and or reinstall AT&T CSC/OS on your phone. XAA/ATT will have the AT&T boot logo. XAA/XAA (generic US use, ATT/T-Mobile compatible) will not.

Hello peeps, i have installed the latest firmware for the SM-G930F from Belgium (G930FXXS3ERL4_G930FVFG3ERJF_PRO) but somehow the carrier apps from vodafone get installed when booting into the system even though the Proximus app should be installed... I have tried to reinstall it multiple time and still have the same outcome? had this problem with my S6 Edge in the past too but i fixed it somehow (I didn't fix it but it fixed itself tho XD)

There is only one reason this happens, the firmware is not an unbranded international version.
Complete waste of time messing about with Belgian, French,German version etc just Download the BTU firmware from sammobile or direct from Samsung. It's says United Kingdom but it's basically western Europe unbranded.

So if i download and install the BTU version what will be different rom the belgian software? Like i remember with my s4 i used to install BTU firmware all the time because there wasn't one for belgium, but didn't notice anything different with my sim card... so i hope this will be the same that i still have the functionallity like i had before i flashed custom roms

The BTU stock holds all the csc codes, base bands, network functions for all of the European region which means once it connects to the network in your country, it automatically detects which system files to use so you "don't notice anything different" than if you had installed country specific like Belgian.
There is always one stock which hold everything for a region, in Europe its the UK unbranded, generic, international, BTU version. It works everywhere in Europe.
okay so i've installed the btu version and it worked just fine, except it was a little slower and idk why. but when i tried to use mobile networks it wouldn't work so i checked my apn settings and my provider wasn't in there so i had to add it manually wich for me turned into an even slower experience on my phone... I really don't know what i did wrong or what happend, so is it possible to get a detailed instruction to flash the stock oreo rom? and also a how to for rooting stock oreo with magisk? because my guess would be that something went wrong when rooting

Hello well unfortunately Belgium isn't important enough country to have your own unbranded stock firmware.
APN settings should install automatically when you connect to mobile network in your country.
There is a specific guide to follow to root S7 on Oreo, please google and follow it exactly.
Also BTU is a stock Oreo ROM.
