Hello
I bought an s8+ from HK which is the dual SIM Snapdragon version (G9550). Using it here in Australia, everything works as expected as it supports all of our bands, however VoLTE does not work. I've read this is because the CSC does not match a local CSC.
Unfortunately there are no Snapdragon versions sold here, hence no firmware with the Aus CSC (XSA) that will support VoLTE (as I read you can't flash the Exynos ROM onto the Snapdragon).
Is there any way I can enable VoLTE? Can I somehow change the CSC without an official ROM? Like go into the G9550 ROM and replace the CSC with the Aus CSC?
The only other region with the Snapdragon is the US from what I can tell, which probably wouldn't enable VoLTE either.
Any advice is appreciated
Thanks.

You may root and then flash your csc zip (or simply replace the CSC files in the custom rom with your CSC files). You should get VoLTE. Download Multi CSC file from here and extract your csc.
I do the same but with India CSC on USA snapdragon models.

Thanks nimms. This is pretty much exactly what I was after, except I cannot root the phone (work required Knox so I can't trip it ). I was hoping I could do somthing like the above, only via Odin, but it sounds like you can't change the CSC without rooting the phone due to making system changes.
Try this code in dialer *#272*imei# and change your csc from there

Hi
As far as I'm concerned, this is not possible without tripping the Knox counter. And if you try flashing the XSA CSC (via Odin), you will definitely soft brick your phone
ims setting. maybe can fix your issue ,just download a hidden app display. then you can open ins setting

Odin won't even flash it, It's pretty hard to soft brick this phone with official tools and firmware.

Yes
Odin won't flash it but if you try to flash it and after that you reboot, you will stuck at download mode. Only by flashing the correct files, will make it boot

Interesting.
Another question...the only difference I've noticed between the 9550 (HK) and 955U (US) is that the US version does not have Band 28 but the HK version does, which we do use here in Aus.
If I flashed a US firmware (which has the same S835 SoC), would I lose Band28, or would the modem still be able to use it?
EDIT: what if I only flashed the CP file (modem), is this interchangeable between the different SoCs? Could I flash the XSA CP (modem) onto another ROM, or will this soft-brick?

My IMS is saying "Not registered" in the about phone. I can't seem to do anything about it, and the hidden menu doesn't give me the option to change it.
IMS setting is located explicitly on "Settings -> Mobile Networks -> Access Point Names"
The best bet you may try is to find a Samsung phone thats currently in VoLTE then copy IMS apn settings onto you phone (you manually input the settings).

Do not enter people astray, ADB Sideload It's not working - error "signature verification failed"
need ROOT
VD2-CSC-S8S8p
MY Galaxy S8+ SM-G9550, SW - G9550ZHU2AQL2
Just download an official ROM (A variant from a country that supports VoLTE) for ur model from sammobile or u might even find it on the xda forum and flash it via odin with Home CSC.
It works well... No need to root n KNOX counter wont be tripped...
PS: Backup data.. They will be lost in the process.
Now we're talking about ADB, not ODIN or TWRP.
Flash via ADB Sideload - not possible. You understand me. Smartphones snapdragon not flash Exynos SW. You can only edit an existing profile CSC or add new CSC.
Example:
my smartphone TGY (snapdragon model SW)
but I live in the region of SER (EXYNOS MODEL SW)

But as far as i know, Exynos CSCs also dont go with the Snapdragon CSCs... I could be wrong.
Hi all
I just purchased the International S8+ dual Sim variant, the G955FD, from eBay.
I live in Canada and will be using both a Telus Sim and a Rogers Sim.
Is there anything I need to worry about regarding the CSC type?
I found this thread, https://forum.xda-developers.com/ga...ility-flashable-csc-selection-v1-0-0-t3605264
So it seems easy enough - I just don't know if and when I need to change the type.
And should I even be changing it to Telus or Rogers, since they don't have this variant?
And yes this is my first Samsung phone
And input is appreciated!
Edit: if it matters, I don't use wifi calling for either Telus or Rogers. I also plan on simply rooting the phone with magisk to make some mods, and put on Android pay
Just curious. Where was your Duos sourced from?

Great question.
As I did more reading on the device I checked the eBay listing and didn't see exactly where it's sourced from. I should have it in hand by Wednesday and I'll try to validate then. What should I be looking for?
Is there a specific source country that works better than others?

Firstly, congratulations on the new phone. I've got a 955FD as well.
It doesn't matter where the phone is sourced from, although if you want to check, you can go in to settings > about > software information > service provider information and see the CSCs listed there, in this format 'XXX/XXX/XXX'
The first one is the active CSC on the device at the time of you checking, the second one is the CSC for the SIM card currently being used, and the third CSC which can not be changed at ALL is the one from which country the device was sourced.
I'm in Pakistan so for me the CSC format is: PAK/PAK/MID
First two are PAK because that's the CSC for my SIM card and because it's the active CSC on my device, however the last one always remains as MID since that's where my device was imported from.
Canada has no CSCs available for the G955FD sicne it's the Exynos variant and the one sold in Canda is the G955W which is Single SIM and SD835, however the CSCs should work regardless of device variant. You can flash the CSC for whichever is your main SIM card, or whichever you use more often. Either Telus or Rogers, entirely up to you.
The benefits of flashing your carriers CSC is getting stuff like VoLTE and WiFi calling (and sometimes even 4G+/LTE+) to work. No harm in doing it since you're going to root anyway, so make sure to flash whichever one you prefer.
Magisk, rooting, mods, that's all fine, but do confirm properly about Android Pay before actually going ahead and rooting.
Samsung Pay will not work in Canada with the 955FD, and will definitely not work anywhere at all once you've rooted and tripped the KNOX warranty counter. Android Pay can be tricked into working by passing SafetyNet with Magisk, not sure if this still works or not though.
Other than that you should't have any issues.
If you've got any more questions, just tag me or quote this post and I'll be happy to help.

Thank you!
The break down is very much appreciated.
Is there any issue with flashing (via TWRP or Odin?) random CSCs?
Since there is no G955FD in Canada, I don't want to break anything.
I'm very comfortable with flashing and modding the heck out of Android phones, but Samsung seems to be a totally different ball game lol
I obtained a Galaxy S8+ G955FD Dual Sim from e-Bay as well, sourced from UAE. I was able to register US issued MasterCard and Visa on Samsung Pay.
I am on T-Mobile, other than not having WIFI calling, the G955FD works great. Rooting the phone would most likely break the Samsung Pay. So that is a decision you need to make.

No issues at all. Plenty of people in the US using the Exynos variants and they've all flashed the necessary CSCs when required.
Flash TWRP using Odin and then use the flashable CSC selection mod to choose whatever CSC you'd like to flash.

Thanks guys.
I'll assume that flashing TWRP is going to trip knox, right? therefore flashing a localized CSC is going to require me tripping knox.
Which hey, if Android Pay works fine then i don't need to use Samsung Pay i guess.
If i dont change my CSC, then will my phone receive OTAs when they're released in whatever country its sourced from?
Will changing my CSC to a Canadian one mean i'll start seeing Canadian OTAs?
What about manually flashing official images? Do i have to make sure that the file i'm using matches the CSC as well?
And lastly, are the S8 and S8+ images the same file? Or are ROMs for the S8 100% compatible with the S8+?

Flashing anything other than a Samsung Stock ROM will trip KNOX. Including TWRP. The Canadian CSC using the flashable CSC selector will have no effect on KNOX since it'll already have been tripped because of TWRP.
If you don't change your CSC, and are rooted with Magisk and have mods, you won't get any OTAs since the phone is rooted.
And no, changing to a Canadian CSC will not get you Canadian OTAs since the Canadian variant has the Snapdragon 835 and the 955FD you're getting has an Exynos 8895, so OTAs and stock ROMs are most definitely not interchangeable.
Manually flashing stock ROMs is possible, I suggest you flash the newest one available when you get the phone, which is G955FXXU1AQK7. And honestly, because there's been a major overhaul in how CSCs work on the S8, you can just grab any firmware and flash it and it'll stay on the CSC your phone came from because it can't switch to a Canadian one without you manually doing it.
S8/S8+ images are not the same and you can't flash S8 images on an S8+ or S8+ images on an S8.
Only S8+ (G955F/G955FD) stock ROMs will work on your phone.
However, since you're going through all the effort to root, change CSC and flash Magisk Mods, might as well use a custom ROM?
They get updated regularly so you don't have to keep flashing the stock ROM, and you can still have root, CSC mods and everything but with a few extra features and possibly better performance.

So maybe the first think i do is try and see how long i can go without having to root it / put on TWRP.
If i dont touch anything, including the CSC, will i receive OTAs as the source country gets them ? or am i out of band and therefore am on my own?

It is indeed a UAE phone, good place to be sourced from since XSG gets updates fairly quickly compared to other CSCs.
What issue did you face when restoring the Google backup and how exactly did you try to restore it?
Some people have reported that the Samsung Pay app installed on XSG phones works well in other countries, so you can try that out if you want, otherwise Android Pay should work fine.

Regarding the backups; I was expecting to log in to this phone and get all my apps that were installed on my last phone.
But then i realized that htis is a brand new phone and i dont have a backup to restore to!
So i just manually installed the apps i needed and was on my way.

If your previous phone is an android phone and you use Google ID on that phone, you should have no problem restoring your apps. The Play Store remembers your Google ID and all of your apps should be restored if you log in with you Google ID.
Im noticing now that of my 2 SIM cards, one is usually around 80% strength, while the other is around 50% strength.
is this possibly an issue with using the wrong CSC for my region?
Or maybe since only one SIM can use LTE at a time, the other SIM is stuck on 2g/3g and it just has crappy reception becuase those towers arnt really in use anymore in my area?

Yeah, that is probably the case.
I had taken my 955FD to UAE earlier this year, used my local UAE SIM in slot 1 for LTE, and my Pakistani SIM card in slot 2 so I could still get texts on that number. Battery life did take a significant hit since the signal strength on one of the SIMs was quite low.
Changing CSCs may or may not have an effect on the signal strength. A good way to check is by using the SIM with poor signal strength in another phone with the same network mode, and see if you get the same results, if so, changing CSC will do nothing. If the difference is very large, then you could consider flashing the CSC although I wouldn't recommend rooting your phone just for a CSC change, especially if you aren't facing difficulties in making calls/sending texts/using data.
I have a 955FD XSG also. Using AT&T. I managed to enable VoLTE by quickly putting the sim on an att branded phone and returning the sim to my phone. I now have the VoLTE toggle and calls are placed over LTE but I can't seem to get the wifi calling toggle to appear.

Hello,
I am going to attempt to Flash my Sprint S7 Edge with current Firmware version G935PVPS8CRK1 to the Unlocked firmware of G935UUES8CRK1 as I have ported out of Sprint and need to enable all LTE bands for a different network now.
My questions are
Can this be done for the above firmware versions and will it enable all LTE bands if successful ?
In the SAMMOBILE page, there are different variants for the SMG935U including one for Sprint. I was assuming that all 935U variants would be identical, but I guess I'm mistaken. So, should I download the Sprint version of SMG835U or something else ?

Never mind, I was able to flash the G935UUES8CRK1 firmware. Also, in Odin I tried with the HOME CSC. Although Odin showed a successful status, my device went into a dm verity boot loop. Then I had to flash it again with the regular CSC file and it worked.
I'm about to do the same thing, were you able to use LTE and VOLTE? Or access other bands that didn't work while on the sprint firmware? Right now i have the sm-g935p and am using it with t-mobile. I can only get 3g speed and have voice working or LTE with no voice.
Yeah, LTE was working. Band 40 which was otherwise disabled in the Sprint firmware was open and LTE Discovery app confirmed it. Not sure about VoLTE.

Yes. The bootloader was updated a few months ago. There is a thread here with files and instructions.

I bought a new S7 (G930F) at ebay. When it arrived i wanted to update to the newest firmware, but i got an error notification.
I contacted Samsung and they told me to send it in.
They checked it and told me, that they are not willing to help because the phone is flashed with a wrong firmware. I bought it as a new device. This is unpleasant.
The seller doesn't answer my messages, so i thought maybe i can flash a new firmware by myself. The actual firmware is working but it is outdated. (1. August 2018)
But how can i find out which firmware is correct for this phone? How to say if it is exynos or snapdragon?
The phone information
Modellnummer: SM-930F
Seriennummer: 5AF94C0C
Buildnummer: R16NW.G930FFXXU7CRH2
Kernel: 3.18.71-14274519 [email protected] #1
Basisband: G930FFXXU7CRH2
Android 8.0.0
Samsung Experience: 9.0
I would like to flash the latest firmware and i want to use the phone in germany. Can somebody identify the correct firmware?
Thanks a lot
What does the phone say in download mode? The ROM can be modified to lie about the model and firmware, but download mode will tell you the truth.
If download mode says it's a G930F then it's Exynos, if it says G930U/V/T/A then it's Snapdragon.
If it is a G930F then good news is you can just flash whatever G930F firmware you want over top what's on it. If it's Snapdragon then you're a bit stuffed, you can't flash Exynos firmware onto Snapdragon.
For updating it if it is G930F my recommendation would be to find out the region code for your device, e.g. from here https://updato.com/firmware-archive...act=1&r=DBT,XEG,DCO,DDE,VIA,DTM,VD2&v=&rpp=15 then download the firmware using that region code with SamFirm tool https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Download Mode says SM-G930V
I'm doomed
Yep that's a common scam. If you can't return to seller the next best thing would be to flash the G930U firmware, which is the generic unlocked firmware for Snapdragon.
It won't give you the equivalent experience, but it will remove any bloat and give you a carrier unlocked phone experience.
You can use the same methods I mentioned to get your hands on the latest G930U firmware and update the device, but you may need this specific Odin version to flash G930U over G930V https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Thanks. Does TMK, TFN, TMB,... make a difference when the phone is used in germany?
Should i flash all 5 files:?:
AP
BL
CP
CSC
Home
I tried and my result is: Flashing only AP was not enough. Flashing all 5 worked fine for me. I chose TMK and even LTE is working. Thanks a lot.
Glad its working, for reference CSC and Home_CSC are both CSC files and you usually pick just one. Home_CSC doesn't do a data wipe, CSC does.
But when changing from G930V to G930U it's always safest to do the CSC wipe.
I'm not too familiar with this community or android rooting in general but I still want to see what I can do. I want to know more than just the state of rooting, is there a way to unlock the boot loader, is there a way I can remove some (if not all) of the preinstalled spyware and replace it, what can I do to better protect my privacy? I figured I'd check out this community as this is where I was lead when I wanted to root my old Kindle Fire and since this community doesn't just direct to sketchy proprietary tools like kingroot (or maybe you all do, IDK I haven't been here very long). If I could remove alot of the spyware/bloatware I wouldn't be as concerned with rooting or flashing a custom rom as those would be just nice to have if I could get the preinstalled OS to be more privacy focused. I know I can't really escape google since they're embedded right into android but what can I do about Samsung? If I can't do anything on the device I would still like to know if there is a list of domains I could block using a pi-hole. Thanks if anyone has any info, also my phone is from the T-Mobile distribution, I feel like that probably matters.

The reason I specified replace is that I already tried this and it broke nearly everything, for example:
despite the fact I have a different keyboard, all keyboards broke, I couldn't get the keyboard to show up.
The entire OS became very unstable

(Sentence removed for stopping confusion)
Without TWRP, replacing the OS will be impossible.
Maybe downgrade to a older phone that has greater custom ROM support.

Not fully bricked, but it can be semibricked, i.e. not completely working as a mobile phone.
Xiaomi boot loops when certain apps are disabled, which is nasty and needs a factory reset to 'unbrick' it. Not sure about Samsung.

I think you removed things that shouldn't have been, or you didn't have the alternate app (e.g. keyboard) set as default. If you look at my post history, you can find the debloat list that I posted, which is 100% safe to remove without affecting the usage in any way whatsoever.
More aggressive debloating is possible, sure, but you risk breaking some things. You can always reinstall whatever you removed with "pm install-existing" as long as you used -k when you removed.

No , unless your rooted. whatever you debloat while unrooted can be fixed doing Factory Reset

It can be rooted with Magisk V23.0 but you need to unlock the bootloader first.
The bootloader is unlockable up to V3 but this is a paid service.
To get rid of this bloatware i would suggest you flash an unlocked firmware.
You can always flash a SM-A326U1 XXA ROM (https://www.sammobile.com/samsung/g...M-A326U1/XAA/download/A326U1UEU3AUF2/1558540/) by using a patched version of ODIN 3.13.1 or later. I was able to do this using ODIN 3.1.4 3B
I now have a TMO SM-A326U without any preinstalled TMO bloat. The XAA rom did not install any TMO software that I noticed at a high level and seems like a plan stock A32 5G.
Just make sure the SM-A326U1 baseband is the same version or high than the installed SM-A326U. The base band number will be the 5th to last number in on the About page under baseband.
Edit * I was checking my computer and noticed I had the SM-A326U1 roms for XAA and TMK. I can’t recall if XAA gave me an issue during the flash and I needed to use TMK, but the end result is, my A32 5G has no TMO bloatware installed.
I hope this helps someone.

The XAA and TMB are what are referrred to as CSC codes. Each carrier has their own:
ACG – Nextech/C Spire
ATT – AT&T
CCT – Comcast
LRA – Bluegrass Cellular
SPR – Sprint (CDMA)
TFN – Tracfone
TMB – T-Mobile
USC – US Cellular
VMU – Virgin Mobile USA
VZW – Verizon
XAA – USA (unbranded/unlocked/default)
XAS – USA (unbranded/unlocked)
ODIN is software used to flash firmware on to Samsung devices while in Download mode. I believe you need to use a patched version of ODIN to cross flash devices. Regular ODIN will most likely error out during the flashing process.
The SM-A326U is a carrier branded device which is why you will probably not find a ROM with a CSC code of XAA for these devies.
The SM-A326U1 I believe is the carrier unlocked version of the device. Regardless of the CSC you flash, don’t expect to get SM-A326U TMB flashed with the SM-A326U1 XAA firmware to enable OEM Unlock in the Developer Settings. It hasn’t appeared for me and I wouldn’t expect it to.
Please feel free to correct any of my assumptions above. I’m an iPhone guy using this phone with my ASUS router as a failover if my ISP goes down. Just tinkering with it from time to time.

OEM unlock wont appear on the A326U.
The SM-A326U1 XAA & SM-A326U1 USC should be the debranded versions.
The XAA FW causes CSC to revert Whilst the USC doesnt.
Theres is NO XAS FW for this device.

So from my understanding:
There is a tool known as ODIN, this can be used to flash new roms
and from what I seem to know
I am most likely running a TMB version of the ROM as it was the default for my phone as it is a TMobile OEM version
So my question is now this:
How can I get a working version of ODIN
Where can I find a safe XAS rom to flash
I don't know if my phone is unlocked, if my phone is still locked to TMobile, could this mess with anything?
I am using SM-A326U not SM-A326U1, I assume the 1 version is unlocked?

ODIN is the software used to flash ROMS on to Samsung devices. You will want to look for ODIN 3.1.4 3B Patched On the forums or a search engine. The patched version of ODIN will allow you to flash ROMS with different CSC codes. It removes this restriction.
You are correct that the CSC code for your device is TMB. The CSC codes I listed above are some examples, not a complete list. There are no XAS CSC ROMs for this device that I am aware of, just as financeledger stated.
Your Samsung A32 5G is actually the SM-A326U model, but the SM-A326U1 roms also work on these phones, provided you use the patched ODIN. Only the SM-A326U1 has a XAA CSC rom which is bloat free. I have not tried the USC variant but I switched between the SM-A326U TMB and SM-326U1 XAA ROMs and back last night without any issues. You can find the ROMS at Sammobile.com SM-326U1 Roms it will be the third one in the list with the carrier name of Unknown https://www.sammobile.com/samsung/g...M-A326U1/XAA/download/A326U1UEU3AUF2/1558540/

Doing this will not unlock the phone in any way, shape, or form. All this does is provides you with an A32 5G without any carrier bloat. The boot loader still cannot be unlocked and the sim will remain locked until you’ve met T-Mobile’s conditions for unlocking.
I’d recommend on reading up on how to use ODIN properly as you can brick your device if it is not used correctly. Feel free to reply back if you still have questions. I’m not knowledgable enough to understand what financeledger meant when they said the CSC gets reset using the XAA vs USC rom. Hopefully they can provide some additional details regarding that.
Ok
to be sure I get it right:
Here is what I shal do:
1: Download https://forum.xda-developers.com/t/patched-odin-3-13-1.3762572/
2: Download the XAA ROM for the SM-A326U
3: Flash the ROM with ODIN
4: Hope I don't brick my phone
Is this right?
