I'm not as concerned about this for ROM flashing. I'm wanting to find out if my G920T can use G920I or G920F modems/bootloaders, etc.
Here's my deal. I have a T-Mobile G920T. To unlock this phone I need to get away from the G920T modem. I previously had a G920T1 (MetroPCS) firmware set installed and it worked great, but the rom sucked.
I've since restored back to stock G920T and i've rooted/twrp, but I see other ROM's and I'd like to give them a shot. The catch - they all say I need to have the newest OI7 firmware installed. I'm still on the G920T sim locked OH8. The only OI7 modems/bootloaders I can find are for the G920F variant. I can't find OI7 for the G920T1 variant. I don't know if the G920F variant will sim unlock my phone. I don't want to brick my phone to figure that out, so this is the reason why I posted this question. I can flash ROM's all day long, but if I can't use my Cricket sim when I'm out in BFE then the ROM is pointless.
Does anyone understand what I'm asking?

DO NOT flash any FIrmewares through odin if its isn't your model number, if you purchased your phone and don't have an EIP you could sim unlock with the app, so any rom your on unless its not Touch wiz based (aren't any available besides touchwiz)
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.
This is my first post... All I know about phones I've learned from this great website. I hope this is a chance to give back.
I've been playing with flashing either of these carrier firmwares on a few different Samsung phones. One being a production model the Galaxy On5. I do not know if this is an exploit or not... but this is what I did and the results of both.
SM-G550T - Galaxy On5 T-Mobile
T-Mobile Sim
I flashed SuperStarz Rom (Don't know how to link it)
His rom however is a Metro based rom..
I hit the device unlock app just for fun and to my shock it actually unlocked it. I've confirmed this with an AT&T sim card thus far. This model and account does not meet the criteria at all for the device unlock app stock to this phone.
Well I was curious..
SM-530T1 Galaxy Grand Prime
T-Mobile Sim
Tried stock unlock app... No success...
Flashed stock tmo firmware and tried again... it worked. Confirmed with a Wal-Mart family plan sim... and AT&T.
Please if anyone has the capability to try this and confirm it, let us know what happened.
Thank you!!
*I realize now this may be the wrong place to post this*
*UPDATE 4/3/17 - I performed a complete wipe and unroot on the On5... tried the unlock app for kicks... and it failed.
Because it was already unlocked!!!!*
Just did the same with the Grand Prime with the same result... seems as tho it might be legit. If someone else can confirm this I'll write a quick tut up for everyone. I also learned from my buddy that tried this after I explained what I was doing... he took the S4 Att and flashed tmo on it... and unlocked it. Flashed OG firm and remained unlocked. Or so he says... I will confirm later.
what unlocked it? the metropcs device unlock app?
Yes. And the Tmobile Unlock App on the other device.
Just tested with Galaxy Grand Express with success. Please... Anyone else confirm this??
Failing never felt so good!!! (On5)
So....
It seems to work well with later production models... Samsung Tmo Metro Att... and minutes ago with my Tmo sim, an older LG Boost phone.
Pls Anyone with any type of multi firmware capable phone, able to flash tmo or metro firms with the unlock app.. try this and let me know the results. I will be posting a full tut with screens in the AM.
I'm pretty sure I'm dying from H1N1 or Sars.... when I'm well enough to think I'll post tut.
metro galaxy grand prime unlock?
I have a MetroPCS Galaxy Grand Prime I'm trying to figure out how to unlock. I rooted it, flashed it with a paired down stock BUT I think that paired down stock got rid of the 'device unlock' app that was on my old Samsung Galaxy Core Prime because when I used that app on THAT phone it worked perfectly but I don't know how to unlock this phone or even if it IS locked (have no clue how to find out if it is). I ordered a global FreedomPop sim card to stick into this phone and give to my little girl (I want it for the tracking capabilities only for the most part, the rest I'm locking up).
This is the closest thread I can find about this subject. Any help would be deeply appreciated. I'm not a super genius for phones or programming but I can figure out how to get into the build and tinker if given the right instructions. I don't even know the mechanics of how phones are locked, though, so maybe that won't work. Again, not a super genius. Thanks, y'all.
Hi, i tried this today with a Galaxy on5 Tmobile (G550T) and didn't work. Had latest firmware installed, then installed twrp, backed up stock rom and installed Superstarz rom. MetroPCS device unlock app keeps saying 'Unlock Failed'.
Just reporting so others don't try in vain.
Yep, it's an oldie and moldie!?
So, these past couple of days I've been trying to find a way to get my unlocked ATT Galaxy S7 Active to work with Verizon.
Well, I have read and read and can't seem to get it done. I just realized that it was an "active" which means its not a normal galaxy S7, I guess. I have read that flashing with the U firmware would be best, but every time I've found one that I thought would work it never has. I've tried both on a mac using the ported version of odin for mac which I couldn't get to work at all. I have also tried going with the Oreo OS as well as the one before it, but the U versions firmware, and trying to install them with the Odin 3.13 software using Vmware and it just constantly fails. is it even possible to flash the firmware on this model?
I have he ATT Galaxy S7 Active Model number: SM-G891A

This is why i never buy branded phones!
The rubbish ATT&T active is on a GSM baseband and Verizon use CDMA so your phone won't work on Verizon until you unlock the CDMA radio software on the phone.
Finally got my g891a on verizon with stock rom and root
I would be really interested to see how you did it. I'm in that situation now. I have the G891A and my carrier is switching from running on ATT network to Verizon. I like this phone (I know it is getting some age on it) and it still does all I need/want and I really don't want to give it up.
