[SM-G920R7] S6 Thread - Galaxy S6 Q&A, Help & Troubleshooting

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.

[Q] 404 to 4.2 upgrade

I trying to find a working firmware for verizon s3 sch-i535 I have it unlocked using odin. T-Mobile [who I want to use]
confirmed my phone is unlocked but they can't connect because my firmware needs to be updated from 404. I went and tried
to get update but run into webpage not found Does anyone have direct download for updates.
Every site I go to is a big runaround. It can't be that complicated can it? Hope I get some help here. Thanks.

T-Mobile = GSM
"This is not a GSM device, it will not work on any GSM network worldwide."
You can try whatever you want, the phone will only support carriers using CDMA
You can find every firmware that has been officially released at SamMobile
Thankyou. For getting back.I still want to upgrade the firmware 404 is old

If you already checked SamMobile you saw that you can choose between:
4.1.2
4.3
4.4.2
There is no reason for not using KitKat 4.4.2
Once installed you can flash latest TWRP using ODIN and then flash SuperSU (For root access) using TWRP. Rott access is highly suggested to remove the bunch of bloatware coming with Samsung's firmware and for grant sd card r/w access for all your apps.
I knew that my phone is unlocked so I did a lot of reading and found that if I go into service mode and enable hidden menus that I could
go into mobile networks then choose other networks. There it is GSM! now the next window is a menu to choose band or all bands.
now I took the battery out and installed the T-Mobile Sim powered back up and get a message: Welcome to T-Mobile. Tried making a call
IT WORKS! TEXT ok Internet ok. This was all done while still running stock 404 firmware. I'm no andriod genius and don;t know why all
the posts I've read saying it can;t be done. All I did was use the advise you guys gave did the proper download to unlock and root.
This issue is resolved. Thank you!

Screwed up my SM-G930VL, please help!!

Hi,
I bought a SM-G930VL (tracphone branded, but verizon compatible) galaxy s7 for a pretty good price, however the advanced and wifi calling were not options (even though verizon told me they were before I purchased). I decided I would try to flash the VZW firmware from sammobile through odin, but it did not work. It originally gave me the ext4 error, but then flashing the csc fixed that. I then flashed the AP file, but it finished very quickly (about 3.5 min) and now will only boot into recovery when powered up.
Is there anything I can do to save my phone, or have I permanently screwed it up?
Thanks
holy sh*t got it working. Flashed the BL, AP, CP, and CSC files and it booted to welcome screen!!
Thanks all (and hopefully this helps anyone in the future who runs into this predicament)
It is currently checking wifi connection so hopefully all is well!
Edit: Is there a way to edit the title? That way this could be maybe help the next person rather than getting ignored.

Hi, want to ask a few questions. were you able to fully flash the Verizon firmware to this model with no issues? The phone is also supposed to be factory unlocked per my connections with reps.
Did the phone fully change to a SM-G930V, showing in settings and in Odin mode?
Yes I was able to fully flash Verizon and I have working wifi calling and advanced calling. In settings it shows up as V not VL as well. As far as I understand it is the exact same hardware just different software running on it

Great, i flashed one yesterday for a friend via teamviewer and even changed the model as SM-G930V in odin mode. So I guess due to this the phone has now a locked bootloader and ended up being converted to a full Verizon galaxy S7. Only thing it did not take his Metro PCS sim card. Unsure it would take any other carrier sim cards.

Was the boot loader originally unlockable? I was under the impression that all SD versions were locked down right. That's great that you got it to work also!

It seems it was as it allowed me to flash the verizon bootloader and full firmware. Normally tracfones only allow to flash part of a firmware and rejects all bootloader partitions.
Is bootloader locked after flash g930v firmware. Or can I flash back to straight talk?

There were reports of someone flashing the phone to an SM-G930U (Unlocked US S7). So apparently they are interflashable. I however have not gone to that extent as am yet to get my one to thinker with. I flashed previously to a SM-G930V via teamviewer for a friend. You can search the threads and verify.

You probably figured it by now, but MetroPCS is the only retarded carrier that locks SIM to IMEI. So if you want to use MetroPCS on any other phone than the one you currently have it on, you need to call customer service and give them your new phone's IMEI. Then your new phone will start working. If you want to switch back to your old MetroPCS phone you need to call them again and give them that IMEI, which is retarded. I don't know why they do that but it's really annoying if you frequently switch phones.
I have a 935V (S7 Edge Verizon) and now have 935U ROM on it using Tracfone. Initially I have Tracfone's Verizon service but I wanted the freedom to easily move from one phone to another so I converted it to a Tracfone-GSM(ATT) and been using it in my Verizon S7 Edge (with 935U ROM) and iPhone SE without any problem.

Could you add links to everything you used? I have the same model using straight talk and I want to be able to have a backup firmware to flash in case I ever mess up my phone (which seems to be a trend). And have you had any issues at all? Like, does everything work okay?

I too would like to know if you could please provide links. Im rather new to this, the only other phone ive ever flashed rooted and put custom rom on was a Evo. But alls im looking to do is get my s7 rooted and it would be nice to have it flashed to Verizon first seeing as there root guide is for verison phone and firmware.

I bricked my SM-930VL too and it's not letting me flash anything back to stock. No clue what to do

Any way to flash G930T firmware on a G930P that is on QJ3 current Sprint firmware?

Basically my phone is updated to Sprint version G930PVPU5BQJ3, and that version apparently has an updated bootloader. T-Mobile's current rom is G930TUVS4BQJ2 with an older bootloader.
Since the QJ3 bootloader is new, I can't successfully flash any firmware that is below QJ3, meaning I can't successfully flash T-Mobile firmware (or unlocked S7 firmware).
Does anybody know if there is anyway around this, or do I need to just wait a month or so for a new version of T-Mobile's rom that has the bootloader updated the same as the Sprint firmware?

Thanks. That's what I thought I but was hoping I was wrong.
firmware bootloader ver.
I have the same problem, no mobile data is killing my functionality. Regardless of whether or not I'm connected to a T-mobile APN I get nothing but calls and messages (texts only no mms/pics), no mobile data of any kind.
Is there a place where the current bootloader priority for some/or all of the various s7 roms (carrier &/or custom) can be looked up? I was considering using a custom rom but need to pick something that will flash with the firmware I have now and work with T-Mobile network. Ideally I would rather use stock carrier rom, since I'm really just a noob trying to use a Sprint phone on T-Mobile network. I really dont want another failed flash and to have to waste more time setting my phone back up with the partial functionality it has now. I'll wait if necessary but I wanted to ask about the bootloader priority and to see if anyone had any other suggestions. Thanks!

Sorry for the question is this new bootloader locked or unlocked. if it is unlocked you can flash a custom bootloader and with that you can flash any rom you like.

Hi. I just joined T-Mobile from Sprint. I entered the APN settings recommended on the tmobile help site, which only worked for about 5 minutes. After calling customer service, I was directed to create another APN profile, basically identical to the one I had originally done, without deleting the first one. After saving and selecting the new profile, go to Settings>General Management>Reset>Reset Network Settings. Push the button to make it so then power cycle. Mine has worked ever since. Of course that was only Monday but still. The tech said that the majority of the time it works although he could not explain why. I talked my wife through the same procedure on her S7 Edge and on hers mms doesn't work. Don't know why.

Sprint S8 Active flash to T-Mobile?

So i've read that the sprint version of the S8 Active is on bootloader v5 and the T-Mobile version is bootloader v1. Is it then possible to flash the T-Mobile firmware onto the Sprint Variant ?. The device is already unlocked but i would like Wifi-calling to work for T-Mobile.
Edit 1: Found this and successfully fully flashed from Sprint to T-Mobile(everything works including Wifi Calling). Only works if you are on bootloader version 1.

I AM NOT THE CREATOR NOR DO I TAKE CREDIT FOR THIS
No apparently the bootloader version must match or be lower so in this case sprint is higher so you can't flash. I've tried and downloaded the tmobile oreo firmware; you'll just get a fail in odin

That is the part i am maybe not understanding. My Sprint S8 active says it is Software version G892USQS1ARC1. Doesn't that mean it is bootloader version 1?
Sorry I was wrong! I actually flashed it! Very happy right now. I was being stupid and using an older version of odin before. Now I successfully flashed sprint to t-mobile oreo with no problems! Use Odin 3.13.1; not prince comsy mod or anything else. So it was bootloader 1 after all; there were some misleading posts without proof. I will trust the software number from now on

ARE YOU SERIOUS?!?! Does wifi calling work for you now?
I'm not sure. How can I check? I'm on Fido which is Canadian carrier without WiFi calling. I'm guessing I'm supposed to be looking for a tmobile WiFi calling app. See attachment screenshot for proof. Still recognizes my phone is from sprint
Yeah i just finished flashing it and i get the same as you. Phone still recognized as Sprint and no WiFi calling. Darn. Android 8.0 Oreo is a huge plus however.

I think we need to follow this guide to change carrier but the thing is there is no factory binary for the s8 active so this guide won't work until there is one...

Actually I have found and flashed a factory binary trying to change it to T-Mobile. The problem I ran into is they want you to download the firmware with "w" after the model number. That is what I think let's you change the option after typing in the code. That firmware is only for s8 I think(not active as it has the s8 model #). Without flashing that, after I typed in the code the only option I had to choose from was sprint. No "xac" or whatever it was.
If I am not mistaken. The model with the "w" is the Canadian version of the s8. The s8 active is US only I think.
So Im getting ready to pick up a Sprint version to use on Att or Tmobile (good deal). Are you guys seeing any issues after flashing? Thanks

The only thing I've notice is there is no option for mobile hotspot( i don't think it was there to begin with, i could be wrong however). Other than that it works perfectly. Great battery life and everything. Flash the userdata to get rid of the Sprint Boot animation if you'd like. I did it and now there is just the "Samsung s8 Active" logo, then lock screen. Goodluck.

After flashing Sprint variant of the device to T-Mobile firmware, do all features work: WiFi Calling, Band 12, VoLTE and Band 71?

WiFi calling works fine on T-Mobile without flashing to T-Mobile firmware. Only issue is that sometimes it gets stuck enabling WiFi calling requiring a reboot. Band 12 also works, its in the Sprint specifications. The big question I wonder about is if band 71 can be enabled.
flash not working?

Did you follow the video I posted?. Ignore all the other comments about things not working. When i updated the OP with the link, it fully flashed the sprint device to T-Mobile. The only thing you have to watch out for, is if your Sprint software is running a new bootloader. You can tell by looking at the baseband version number. This will only work if you are on bootloader 1. My baseband is currently "G892USQS1BRD5". The bootloader version is the 5th character starting from the right. The number 1 before "BRD5".

Question Samsung S21 VZN need unlocked or converted to ATT. Tried odin.. Maybe I am an idiot.

Hello.
Got a free phone from a buddy S21 5G. I am wanting to swap it for the S10* 1tb I gave my wife to use it was a bit expensive. So I'd rather ti go back in the box.
Popped the sim in it, it works makes calls sometimes, sometimes not. Texts seem to always work, I am currently on ATT I would prefer to have that firmware as I live in the stick with ho cell service. ATT has wifi calling which is pretty much a necessity here.
So what exactly do I need to do to get this off the VZN fir
Hello. Could you all provide me the links for what I need? Found a link that had a patched Odin plus the firmware. I installed in booted how I was suppose to. Tried to install in and it errored out. Also. I do not know what file to select for the user data selection, I do not mind deleting all data as it 8s hacked up and can put ti back with smart switch.
Hello, did you manage to flash the phone?, I'm stuck with a similar case, mine is a factory unlocked unit from Verizon, it turns out that even if it is factory unlocked, is locked after a few minutes by verizon, I have tried everything to get rid of the VZW firmware but it seems that Verizon locks the bootloader so I can't flash it (it passes om odin and everything but the firmware doesn't change)
I even paid SamKEY credits to change the CSC but it didn't change either.
