My goal would be to install Cyanogenmod on my SM-G920R7, but haven't been able to find too much help. Any of the rooting methods that seem to work on rest of the S6 variants, doesn't seem to work on this one. There is no TWRP available that I know of.
I would really appreciate any possible help. Thanks in advance.
i have the same problem
I think that this version of the s6 (the cspire version) isn't widely available enough and no one has bothered to make a root for it - ive been searching for a long time and still haven't found anything
I'd like to at least be able to root this thing.. On 5.1.1 now.
I have a rooted cellphone of this version (I purchased it rooted), is there any workaround to unlock GSM/LTE bands on this device?
----
Edit... Okay, so I went back to fresh stock with SmartSwitch, then flashed twrp-3.0.0-0-zerofltespr and Unikernel-v9b-BOH1-920P-100815 via odin 3.10.7, and rooted again... any method to enable gsm on this device yet?

How exactly did you root it again? Was it SM-G920R7?

Yes, it was SM-G920R7... first, I flashed twrp-3.0.0-0-zerofltespr , then Unikernel-v9b-BOH1-920P-100815 , both via ODIN (you can google both files), note these files are NOT for r7 version (they're for sprint version *g920p*) but they'll root the phone.
I ended up getting rid of the phone as there's afaik no way to enable gsm on it

That's not true. I finally rooted that model and got TWRP installed, and followed the steps to get the Sprint Galaxy S4 domestic SIM unlocked. I finally got data and texting working last night, but I can't get calls to work for some reason on an AT&T SIM card. It even shows up at AT&T as my provider. AFIK it is now SIM unlocked, the only thing not working is calls like I said. I'm sooooo close to getting this working. I need people with this phone that are doing the same thing i'm doing! I only paid $50 for it! lol
Can u help me get mine unlocked , ive already rooted the phone.

Any way to get the G920P roms to work on this variant? I've had luck with them with other c-spire/ntelos/r7 phones in the past. I'd like to flash Renegade to it...

Wonder if anyone has got calls working using GSM sim card? I have the cspire G920R7 rooted with LTE data working using AT&T sim.
Won't receive calls (straight to vmail) and when placing calls dialer says CALL ENDED immediatly after dialing.
hmmm.

I'm working on this too. So far I've got the same situation as you, Data works but no calls/text.
in a few weeks the person who wants me to unlock this phone for them is switching carriers and plans on buying a new phone to use until I can unlock the S6, so I'll have more time to mess with it then.
There's a few things I want to try, but I can't post links here (XDA rules).
One involves Rooting and using a service code to unlock the bands (google "TeamUSCellular GSM unlock S6")
The other also requires rooting and involves using "galaxy tools" to unlock the bands (not sure if this app works with marshmallow, though) (google "theandroidsoul how to sim unlock sprint galaxy S6")
My hopes are not high for getting this phone to work fully. I've also been trying to get custom ROMs to work, but I can't get the cell radio to work at all on custom ROMs. Even with the stock SM-G920R7 Kernel straight from the latest update .tar

Thanks for the suggestion, yeah I have tried galaxy tools (GT) to change the phone mode to LTE/GSM auto and tried different CSC values, and accessed the hidden menus through there. The sim unlock in GT asks for a code which I dont know, but the phone doesn't seem to be locked anyway since it doesn't care when I try different sim cards. Weird thing is the GT app doesn't work very well (most hidden menus not working) on the current rom i'm using but worked better on the stock cspire rom. Note, I tried using MSL 000000 in ##3282# data menu and it works but most the settings in there don't seem to be applicable to GSM networks.
Currently I'VE been messing with the build.prop file, also tried the CDMA to GSM flashable zip which edits the build.prop but nothing has gotten better. One time after editing the build.prop the phone would only turn on with a blank screen and vibrate every few seconds, that was SCARY. Also was planning on flashing other radio/modem but having trouble finding many of those files and pulling them from roms seems difficult to get the correct file to flash on odin.

I'm not sure you'll even be able to flash other models' modem..? I can't say I've ever tried.
Anyway, getting your hands on the firmware is easy. Just use SamFirm (http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647)
To use it, just input the model number (SM-G920R7/R4/P/V/T/A) and the region code, then select "auto".
Region codes and model numbers:
C-Spire: ACG (SM-G920R7)
US-Cellular: USC (SM-G920R4)
Sprint: SPR (SM-G920P)
Verizon: VZW (Locked out from download, app can't download) (SM-G920V)
T-mobile: TMB (SM-G920T)
ATT: ATT (Locked out from download, app can't download) (SM-G920A)
This app downloads firmwares directly from Samsung servers, so the download is really fast and guaranteed to be perfect/stock.
**the SM-G920R7 is closest related to the SM-G920R4 (US Cellular) & SM-G920P (Sprint). The US Cellular one recently supports GSM Bands natively without any rooting/messing with hidden settings, so that's where i'd start. You may not even need the baseband/modem, just flash the rom? I'm not sure. Good luck dude It'd be awesome if you get it working
*** Also, make sure you have a backup of your EFS before messing with the modem. Apparently if you flash an incompatible modem you can erase/corrupt the EFS partition and lose your IMEI. Hell, make a FULL backup with TWRP, and make sure that backup is copied over to your computer before doing any flashing. You can't be too careful with this.
Haven't had any luck flashing stock firmware or modems from other models using Odin, errors with a security message or something, tried G920A and G920R4. Probably for the best I suppose. Flashing custom roms has not been a problem, even if the don't work properly. Wonder if there is a test mode or way to use logcat to see why calls don't proceed like normal. Never worked on going CDMA to GSM before, I always did CDMA to CDMA in the past.
Tried and tried to get wifi calling enabled on my G900F but it would never work. I got a suitable pit file and resized the ext4 partition so it installed correctly, but icon would never appear even when wifi calling enabled in settings and enabled by EE.
Got a G930F Galaxy S7 yesterday. It didn't come from EE so should have come with BTU firmware (I didnt check - but it didn't come with EE EVR firmware). It's a carphone warehouse one. It's the non edge version.
EE firmware appeared today on sammobile so I downloaded it and just went for it, but I expected it to fail so I had the BTU version of the firmware downloaded ready to flash to recover my phone.
It installed without a hitch (no ext4 partition error) and so far wifi calling seems to work. The icon appears at the top of the screen and when I make a call I have a big icon on the call screen. I need EE signal to completely drop in the house before I'm sure though, and annoyingly their signal is stronger than usual tonight.
Congratulations, great to know that someone has this working.
I'm thinking of moving to EE when my current contract with Vodafone ends.
Meanwhile I tried the same procedure, but flashing the Vodafone UK firmware that's recently appeared on Sammobile. Flashing just the AP didn't seem to work as the CSC remained as BTU and no WiFi Calling. So I tried it again, this time flashing the CSC as well as AP in Odin. I ended up with what must have been the Vodafone Germany CSC (VD2) and still no WiFi Calling feature. Then tried flashing just the 'HOME...' CSC and soft bricked it. Managed to get back to the original BTU CSC using Kies3. So I'm not sure what's going on with the current Vodafone UK firmware from Sammobile. Either I messed up somehow or the version they currently have is not Voda UK. Not a very productive day.
I didn't even know vodafone had wifi calling.
I flashed the whole lot - AP, BL, CP and CSC. I think you more than likely need to, or at least I did it so I'd covered all the bases.
Vodafone wifi calling is available on the Galaxy S6 and the iPhone 6's. Via an online chat they confirmed S7 supplied from them (IE running Voda firmware) also has it.
After only just recovering from a soft brick I'll probably wait until updated Voda UK firmware appears on sammobile before having another go. Or until someone else confirms success.
Still, good to know that EE's wifi calling is working.

I'd wait a bit longer. S7/Edge aren't enabled for Vodafone wifi calling yet. Check their S7 forum for details but no announcements regarding S7 wifi calling have been made. I'm sure it will come eventually...
Good to see EE can do it from day 1 although the usefulness of Vodafone Wi-Fi calling for me took a huge drop when I learned it doesn't do text messages. Think I'll switch to EE (BT) come contact renewal time.

Thanks moonray. Just checked the Voda eforum - what a shambles. And I wasn't aware of the inability to send texts via Voda's wifi calling.
But I think you may have to go with EE direct to get their wifi calling feature as I've read that BT will not have access to it?
Only issue is BTU firmware drops well before carriers firmwares, so you mat be left behind
@buachaille did you flash the "HOME" file too?
No. How do you even flash that file? I couldn't see an option in odin that would allow me to do it.
What does the home file do anyway?

That shouldnt be EE FW Specific.
I've just bought one of these (via CPW) and on EE. Obvious question, but when my phone arrives tomorrow, I want the EE wifi calling service!
If I grab the fw & flash over odin as usual, I presume it won't invalidate the warranty/screw KNOX etc?

I have no idea. I'm careless when it comes to warranties and because of this I've never cared about tripping Knox.
You are flashing a carrier branded stock unrooted rom so it's not like you are really messing with the phone, but warranties are provided by big business and we all know big business is run and populated by slime who will use any excuse to get out of paying up for stuff. I think they could use the fact that you are on different firmware from that which came on the phone to slide out of their warranty responsibilities.

Agreed, I know what they can be like, even at the best of times! However, if KNOX isn't tripped they won't know! Is there anyway you can just check this in your bootloader to see if it's intact please? No rush!
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.

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?

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+?

I got my S8+ over Thanksgiving and have been using this for less than 2 weeks. I received an OTA update a few days ago. It was an Android security patch dated November 1, 2017. So, I am getting security patch updates.

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.

Thank you
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?

If you don't change anything, you will get CSCs for wherever the phone was sourced from.

Just got the phone!
It's CSC is XSG/XSG/XSG which looks like "United Arab Emirates unbranded"
First thing im noticing is that it's not restoring my Google backups
Is this because it's a samsung phone and i need to use the Samsung backup feature instead?

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.

Yes, i actually just got a notification for an OTA. I think the December security patches.
Which is aweosme, so i'm not going to flash a different CSC because i dont think i need to at this time!
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.
Lastly, yes, i just installed Android Pay and it works perfectly fine.
Thanks for all the help!

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.

WiFi calling won't appear without the AT&T CSC.

It was originally an unlocked model straight from Samsung. I flashed AT&T firmware so I could use some features. I figured this build number would receive OTA updates.
i never got ota updates on my unlocked phone. I've installed 100% at&t stock firmware.

imei and sim is registered maybe that's why wifi calling never worked on mine. lol
Current stock is N950USQU5CRG7
You can dl the update.zip file HERE, copy it to your ext SD card and flash it from recovery. This WILL factory reset

Do you have ATT Rom on it or it the stock Rom from Samsung?
Also, can I ask what you told them to change the IMEI?
I called and they were telling me I can't change the IMEI and that even if we do change it, it would only work on the previous phone... which seems bogus...

Was originally unlocked direct from Samsung, I flashed AT&T software.
I just flashed the update on my own, I don't know if I'll ever get OTA.
I had no problem changing IMEI. It had my old S7 edge IMEI, I used chat to change it to my current Note 8. Then quickly had them switch it to Note 7 IMEI once WIFI calling wouldn't work. They asked no questions both times. Just told them I upgraded phones and need to update my IMEI. I've never called them, just used the chat feature.

Now I have to decide if I want to flash ATT firmware or not...
Hate having to re-setup my phone haha.
So you just used Odin and the ATT firmware correct?
FYI I have been getting ATT OTA updates on my stock SS direct Note 8.

Yep, used Odin and the ATT firmware. I just back everything up using smart switch external storage feature and backed up my Nova Launcher settings. Only thing I don't like is I have to tweak all the settings over again.

One last question.
Did you need to give them the old SIM#?
I have info in my email before returning my Note 7 but nothing on the SIM card # and wonder if that might give me some trouble later on for wifi calling.

You won't get AT&T OTA unless you're in AT&T network with MCC 310 MNC410 (Red pock GSMA has this so it can get AT&T OTA update).

Could you explain this a bit? I don't know what any of that means
You need active AT&T sim cards or AT&T MVNO (Red pockets(310 410 but not Freedompop 310 170) sim card in your phone to get AT&T software update.

My sim card is direct from AT&T. I've been using the same one since I purchased and activated the Note 7 in an AT&T store
Did you flash your phone with AT&T firmware including home CSC or just part of AT&T firmware?
You have to flash complete AT&T firmware to get AT&T OTA.

Hello,
I got SM-G930FD, updated to the latest 8.0/9.0. Baseband version is G930FXXS5ESF3.
I live in Singapore and want to use my US issued credit cards with Samsung Pay but it only allows to Singapore issued credit cards to be added.
Is there a verified and working way to fix the solution, considering that I don't have US SIM card and won't plan to be in US until May next year.
Quick search here and Samsung Forum says that the phone needs to be flashed with the firmware from US. But international S7 models use Exynos, while US S7 use Snapdragon.
Any suggestions?
Thanks

Thanks. Are there a success stories with this setup? There is a thread titled 'Need help to use US Samsung Pay in Canadian S7' (can't post links) and seems that this setup did not work for topic owner.
Separately, if deciding to flash firmware, I guess the right version should be XAC, correct? I have not flashed firmware on Samsung devices yet - at sammobile there is option of is one file or several files flashing. Any differences/preferences? Anything I should be aware of?
And most importantly - will S7 after (assuming successful) flashing be able to use Samsung Pay if I don't have US or canadian SIM cards?

As long as you don't root the device you won't trip Knox. If you trip Knox Sam Pay won't work again on your phone ever. Same with other banking apps.
If you just need to flash firmware then make sure you use Odin and read the guides how to do it. Also use the unbranded firmware as you have mentioned , XAC is unbranded.
One more thing Canadian devices only have 1 SIM slot so if your device uses 2 SIM cards then SIM 2 slot will not work.
If none of this works after flashing just flash your original firmware back to your phone and everything will be fine and left with the original problem of not accepting US card.

Good to know.
Want to update here a situation which to my surprise has resolved itself without any flashing of firmware. It might help others in similar situation as well.
After spending several hours researching, reading and downloading stuff, I decided this time to do full factory reset. After wiping up the phone, I connected only to my wifi, did not put any SIM card inside. Then, when in the process to setup the phone, by connecting to my google and Samsung accounts which have US as location. During setup I put US English and PST as regional/time settings. After downloading and installing Samsung Pay, I didn't allow it to access GPS/location.
Well, after all above, I was able to enter my US issued credit cards at Samsung Pay and activate them.
So... problem resolved.
