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?

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.
Hi community,
A question for many of us in regards to 'unlocking' or "how to unlock" from our carriers, I have done a very simple and silly way to unlock my phone from T-Mobile.
I am currently under SM-G935U Firmware (4API3), coming from SM-G935T's 4APIA Firmware.
Follow these simple steps in order to unlock from your carrier.
***NOTE: THIS METHOD ONLY WORKS IN STOCK FIRMWARES. YOUR DEVICE WILL BREAK IF YOU TRY TO INSTALL UNDER A CUSTOM ROM***
1.- If you have previously installed a custom ROM (Echoe, Tekv2), say bye bye for now. Using Odin latest version (3.12.3), flash Stock Firmware '4APIA'. After set up enable developer options and USB Debugging.
2.- Download SM-G935U's official firmware from SamMobile or Samsung-Firmwares (Make sure you download the TMO region firmware)
3.- Create a new folder on your desktop, copy and paste BL & AP files from the SM-G935U firmware you just downloaded. From the SM-G935T stock firmware you downloaded, copy and paste CP & CSC_HOME files.
*Basically you will have BL/AP from G935U and CP/CSC_HOME from G935T*
4.- Flash these files through ODIN, but WARNING: After flashing your phone will reboot. Go into recovery mode and wipe cache/data + wipe data.
5,- You will get to see a dm-verityverification failed, no mount blah blah blah. Just ignore it. After deleting cache and data reboot again into download mode...BUT THIS TIME ONLY FLASH CP file from G935T while the CSC_HOME you will flash now will be the official G935U file.
6.- After reboot, done.
I was able to install Google Voice
Sounds promising going to try this when I get home, was having all those issues with dm-verity.
Have you tried just wiping the cache and not wiping data with success? (Dirty flashing)
Or we all starting from scratch?
since root with eng kernel makes my phone burn up and kills my battery, even with all the remedies. The g935u is an option I would love to play with.
But how did you unlock the sim? You have the unlocked versions firmware so less bloat and no carrier garbage but the phone itself would appear to still be locked to TMO. Splain.
Hi there. This firmware is so much better than the stock TMO firmware, everything works excellent. I used stock tmo firmware first APIA, next tmo G935U API3 next. I tried your way first on a S7 Edge with bad IMEI and it wasn't working. I used another S7 Edge but this time I flash all the G935U API3 firmware, it work flawlessly with one simple try. Just put AP/BL/CP/CSC and flash with the latest Odin, you wouldn't have problems. My 2 other TMO S7 Edge are on stock G935U and saying official.
Hey can make a video like you did please.

Yes indeed it is. G935U feels great, faster response, no lag at all and for some reason I get 4G LTE even with Roaming (Mexico) I am still with T-Mobile...were you able to UNLOCK the SIM?

Hey bori,
Every time I flash a custom ROM or even going back to stock, I always wipe cache/data. It is just the way I like to do things on my phone, not keeping any traces from previous ROM/FIRMWARE.
Make sure you download the official Firmware from SamMobile or Samsung-Firmware.
I heard updato is a fast download Firmware site.

Well i tried last night but ended up with the same results. Goes perfect in Odin. But boots straight into recovery even though I wiped everything and reflashed cp and home csc from g935t files.
For the TMO and other SM-G935 firmware, check out THEANDROIDSOUL.COM . They have about 90% of all firmware.

I'm not a big fan of stock roms, custom is the way but this TMO G935U FIRMWARE IS THE ****TTT !!!.
The last time I used a stock Rom was from HTC EVO 4G, after that was the Sprint S2 and I never USED ANY PHONES WITHOUT A CUSTOM ROM TILL NOW.
This TMO G935U FIRMWARE, I did a ANTUTU BENCHMARK LAST NIGHT after flashing the firmware. Mennn! The score was higher than the note 7 N9300 by 4000 points, I couldn't believe it. I did a second test samething. The battery performance is excellent.
All mine said was applied multi csc now I get lte+
Nah I didn't try to unlock it yet, I have to get an AT&T sim card or simple mobile card and see if it ask for codes. If that works that will be great for everyone ?.
Which U firmware are you guys flashing and what would be the differences between them? I'm currently on the T-Mobile U firmware.
tried this... asks code also ... but anycode can give message "network successfull".
BUT its not unlocked... still "invalid sim card inserted error" is there.
So this method works or not? I want to know before I take the plunge. Also Dm verity error doesn't sound good either. I had a note edge with that error and it was a major headache.

i was able to flash g935u firmware totally.. but didnt work for me.
Hi all. As far as I can see, the U firmware unlocked the phone. I inserted a SIMPLE MOBILE CARD into my G935T running G935U firmware, the phone boot into like recovery mod but the screen go BLUE and it configures SIM UNLOCKED SYSTEM, then it reboot and walla the phone have service on SIMPLE MOBILE NETWORK. I was very SURPRISED it works because the phone is locked to T-Mobile and only the DEVICE APP to unlock it. So at this point I'm only using the G935U firmware on my G935T, no more T-Mobile firmware bull crap. Next I'll get an AT&T SIM card and try that for 30 days.

I know this is a late response but it's good to know. SimpleMobile has been running under T-Mobile Network, whether your T-Mobile Phone is locked or unlocked it will work when a SimpleMobile Sim is inserted.
network unlock code????
I have searched Reddit and XDA and can't seem to find a good comprehensive guide to switching my phone over to the AT&T firmware. I tried a few different firmware versions and tried flashing them via odin but was unsuccessful.
My phone is an unlocked Sprint S8+ running the sprint firmware. I have had a bunch of problems after switching to AT&T due to this. My phone keeps trying to activate on the sprint network, tells me to setup voicemail and WiFi calling doesn't work.
Even after flashing the AT&T image I still get the sprint startup screen. I have seen guides that say I need to change something via ADB, but those usually involve going to the unlocked image. I use Knox and Samsung pay on a regular basis so I am hesitant to try to much and risk tripping the fuse.
Any help would be much appreciated.
Thanks!
Hello,
I recently got a G7 power T-mobile variant and was trying to get it working on safelink wireless a Verizon mvno. I have it network unlocked and bootloader unlocked and have been able to flash custom roms and my sim is detected but I can't seem to get any calls texting or data on it. I've been perusing the forum here reading everything I can on the issue and feel like I'm 90% of the way there but missing something. For anyone that has gotten Verizon working on their T-mobile G7 please help with how you managed to do it.
I flashed RR and then the Verizon modem but that didn't work. I'm going to try flashing back to stock T-mobile to see if I can get some connectivity.
Anyone have any suggestions?
Thanks
I have already flashed a custom rom to my phone that hasn't had connectivity and the issue is that the custom rom you flashed to your phone doesn't have your regional code for ur area and the tz.mbn file needs to be updated with your area's cod or just re-flash another custom rom because it's rare on how many times I have had to erase completely re-installed new and different Operating Systems to my phone just to learn and try different Roms and only twice have I got a Rom that doesn't support my data.
So just try a different rom from RR and it should be able to work? Should I do a comletely clean install like, wipe system then flash or flash stock rom, then do custom rom over the top?
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.
