[SM-G920R7] S6 Thread

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.

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.

Flashed U firmware to a U1 but no Carrier apps

I have a sm-g715u1 with latest android 11 firmware and flashed the verizon G715USQU7BUC1. Both are latest ota firmware.
Odin (3.141) showed a succesful flash with all 5 bl,ap, cp,csc and userdata put in. The csc file was non home. However, I dont see any verizon apps installed. There were changes and it does show the U version software installed but no verizon apps. I saw no errors in odin and flashed it twice but no change. I did a factory reset from phone app before flashing a second time.
Not sure what i did wrong . I left the SD card in but dont think that matters.
It has verizon splash screen on startup but thats it. The phone is functional but no different than U1
Is this version (3.14.1) of Odin ok for U1 to U flashing?
Should i have factory reset before flashing? Flash from recovery and not the phone software?
Any ideas will be appreciated.

I see that i can no longer access special menus via the dial pad like I did before the flash. Its like a partial install of the userdata file or something.

So things i noticed after the vzw flash: I didnt get the full verizon bloatware and lost some of the samsung unbranded advantages. I have the vzw 4G icon and Hd voice icon during calls and had the video call option. Video calling didnt work and had to call vzw tec support to get it turned on. A ticket was opened to have it done and its now working fine. Before the flash i was told it couldnt be done so flashing to vzw must have helped here. One thing i have noticed is reception in fringe areas after flash in terrible by comparison. It now enters extended network or no signal at all where before it stayed on lte even with 1 bar and could text and call. This must be a PRL difference or something. The unlocked, unbranded version is way way better for fringe areas. In town i noticed no difference.
At this point i could try to enter recovery and wipe then direct to flash the vzw firmware again to see if i get all the bloatware but to be honest the poor signal and tower handoff with the vzw firmware has convinced me that the U1 firmware is better for me overall even if i lose the video calling after switching back.
At least with the U1 version its a little easier to experiment to see what works best.

Question Help - In need of T-mobile unlock app

Hi.
In short I am asking someone who was the T-mobile firmware if they can extract the T-mobile unlock app. I am hoping I can use the unlock app without the need to reflash my phone to the T-mobile firmware.
Long story.
I thought my wife's phone was unlocked succesfully and flashed the unlocked firmware over the T-mobile firmware. Weeks later come to find out it's not actually unlocked we were just using a MVNO that is on T-mobile antenna... which I should have known. Really want to avoid making my wife setup a bunch of stuff again, even after backing up and restoring so looking for some help.
Is anyone able to extract the unlock app, or have a better way of backing up and restoring without the need for root?
TIA

What message are you receiving when you insert Non TMobile or MVNO sim?
AFAIK, you will need TMobile firmware for unlock to work. Newer TMobile phones don't have a dedicated unlock app. It is baked in connection settings.

Was afraid of that. It asks for an unlock code. Will probably have to just bite the bullet and flash back to the TMobile firmware.
Maybe flashing with Home_CSC will work and still allow me to keep my wifes settings intact.

Worth giving a shot with Home_CSC. Also Samsung backup works very well except Samsung Pay/Google Pay which you have to set again.

Ill probably try it tonight. As far as Samsung backup, did you mean smart switch? All the apps, contacts, photos come over but many apps still require setting up again Regardless thanks for the comments!

New T-Mobile devices don't use the unlock app anymore. Device unlock requests are done through connection settings.

Ended up flashing back to T-mobile firmware using Home_CSC instead of CSC and I was able to successfully unlock as well as keep my wifes settings...
But i tried flashing back to unlocked firmware using Home_CSC and couldn't boot. Said user data was corrupt. I tried 4 times without any difference. Luckily I was able to flash back to T-mobile firmware again with Home_CSC and it worked fine
This may be common knowledge I wasnt aware of but it appears:
Unlocked firmware + Home_CSC -> Carrier Firmware is ok
BUT carrier firmware + Home_CSC -> Unlocked Firmware is not
Thanks to anyone to commented and read.

It's contract there I believe

Question Can't change CSC from T-Mobile to Verizon with firmware S908USQU2AVDC

A question from a noob here. I have a T-Mobile S22 Ultra phone which is network unlocked. As I recently I switched from T-Mobile to Verizon, I'm missing some of the features that are Verizon specific, while not needing anything that is T-Mobile specific anymore. From what I understand, Samsung installs multi SCS firmware on most of the phones these days, which can be changed by a dialer code. That however did not work at all.
Another option I've come across is by flashing provider specific (in my case Verizon) firmware as long as firmware version is the same (S908USQU2AVDC). There are a number of articles on how to do it by using Odin. The issues is no matter what I do and what files I select (like by using CSC file instead of HOME_CSC with or without flashing USERDATA file as well) the result is the same. It shows success and reboots and then reports an error and does the full factory reset which ends up back on T-Mobile version.
The question I have if it's even possible? And if so what I'm doing wrong here. Unlocking a bootloader is not really an option for me...

The question I have if it's even possible? And if so what I'm doing wrong here. Unlocking a bootloader is not really an option for me...

In theory, flashing the correct firmware (VERIZON) should work. I would honestly first wipe the device, then flash (clean, not dirty) the Verizon firmware and setup accordingly. I had a similar case with a TMBILE unit (I had changed carriers) and I had managed to use XAA CSC and then when I reverted to TMOBILE SIM it would not "restart and install carrier updates". I had to basically switch the unit to U1 and then revert to U and it finally pulled all the TMO crap.

I may be mistaken since I haven't done this type stuff since S10, but I think you need to first reset the device and flash the unlocked version then when you put the verizon sim in it should provision it. Then you can flash the verizon package if you want the bloat apps. The features may be hit or miss. You may need to activate the features on the verizon website. Some features may never work as the carrier wont push them to IMEI not in their database of branded phones. There may be things you can do in hidden settings with "Activity Launcher" or other methods.
I'm here trying to figure out the same things for Tmobile and a factory Unlocked phone, before I buy.

Thanks a lot for your suggestions guys! I managed to do what I wanted. This is what I ended up doing, first flashed the unbranded U1 version on my phone and on the first boot Verizon sim was provisioned. Then I flashed Verizon firmware and it worked!
