Well I do have a sprint phone and want to know if I can get it to work with a Verizon Pre-Paid SIM, went to Verizon Website and it says my IMEI is ok for working with that. Went and bought the SIM and it just tells me "Invalid SIM". Any help would be appreciated do I need to unlock it? Flash It?
Flash it but it'll only be 3g not 4g,even if it read sim it won't get lte, i flash phone for a living

I guess my question is the towelroot won't work because of my firmware version so I need to do the odin, but it says to use CF-Auto-Root do I use the firmware version I have for Sprint, or download the firmware version to verizon I want?
this is almost exactly is what i'm trying to figure out, just in reverse, because i can get a good local S5 VZW but SPR use different LTE bands.
i know typically the saying is never flash anything for a different carrier of your model, but some people seem to do it with a ymmv statement.
i've read several threads from people talking about carrier rom swap, some casually saying sure it can work, but no updates from OPs or others that said they would try, definitively saying that it worked or failed.
so... has anyone literally gotten something like the Odin flashable firmware at sammobile or someplace for the Verizon VZW sm-g900v and flashed it with the Sprint SPR sm-g900p stock firmware, completely changing its baseband, modem, everything so it now identifies and works the same as a Sprint phone?
or should i just keep waiting for another similarly cheap S5 bundle in a Sprint flavor?
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.

the same network . Use odin to install i have same phone and have mine rooted in this way. So far tried using the sprint version custom rom it will work but you can make phone calls but not the data side for phone internet.

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,
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?

If I flash unbranded FW on a carrier specific device, loke tmo or att for example, would it sim unlock the phone?
If I flash tmo FW on an att s8 would it in turn allow me to use the att original device on tmo? I ask these questions because I feel like it would work for both my questions since flashing the FW flashes both boot, kernel and baseband/radio. The which is needed for signal. Just some theories but would love to know the answers.
Btw, I have a F model S8+ and was planning on buying some US branded devices so I was curious.

No, it will not unlock the phone (Note: Verizon phones are factory unlocked and remain that way after a firmware flash)
Yes, you can flash any carriers FW to a US S8 and use it with a different carrier.
So I understand, your saying if I flash att FW to a T-Mobile s8 I can use it on tmobile? If that is the case, to me that's an unlock of sorts tiny book lol. Just wanna make sure is all

Just realized the typo.....what I meant was, if I flash ATT on a TMO variant I can use ATT while locked to tmo? I'm very unfimiar with combination fw and always opted for the UK models for alot of reasons. Sorry for the confusion of my op question. I know on the s7 and edge if you flashed the US unlocked firmware it not only removed AOL bloat but it unlocked the device. So that is why I ask.

I had a TMobile S7 edge and flashing unlocked firmware never unlocked the device. That's handled by TMobile servers so...
Flashing unlocked firmware will give you just that. The smoother, bloat free firmware from another device but not the actual sim unlock.
I bought an unlocked device and wanted wifi calling so I flashed the g950usqs1aqf7 att firmware with Odin and it worked to enable wifi calling but I'm unable to get any ota updates and I hate the bloat. Is it possible to get WiFi calling with an unlocked firmware like this one? Also what is the difference between the U and U1 firmware variants?

There are plenty of threads on this, but I don't think anyone was ever successful. I flashed att Oreo to my u1 and got the options, but can't get my company to change my imei back.... My personal phone sim works fine. Quit at that point since it's an Ims registration error. You can try merging the wifi calling apks, but I'm pretty sure it's baked pretty deep in the os. The Verizon guys got some of it working. You can try their threads and see if any of it applies to us.

The thread right below this one entitled Oreo ota has all the details and it needs to be side loaded through adb. Not Odin. But you will need to Odin the 950u base to get off u1

Ok thanks. I need to flash anyways because I'm having terrible battery issues and just debating whether to go to a newer version of 950u or back to U1 and losing WiFi calling. In your opinion is oreo beta worth it
So just to confirm, I have read everything, but I am just a bit confused. If I flashed the unlocked firmware via modified odin on a locked AT&T S8 it will remove a lot of the carrier bloat and give my my wifi hotspot back, but remove wifi calling. Similar to when I flashed the T-Mobile firmware on my AT&T S7 and got rid of a ton of the AT&T bloatware but was able to activate my wifi hotspot but lost wifi calling. I stay locked to AT&T which is fine that is not my purpose for flashing

and can you re-upload the link is dead now
The links don't work. Any chance you've still got the firmware? I've been overseas since october. I have an unlocked AT&T phone that I intend to keep using when I get back, so I want to keep it AT&T FW.
Hi.
I have a G955U Galaxy S8+ AT&T Factory Unlocked on Android 7.0
Baseband Version: G955USQU1AQD9
Android Security Patch Level - April 1, 2017
I no longer live in the US, and currently in the Philippines. Phone works great and the signal is too and all, but I cannot get OTA updates.
Can I just download the firmware file in this thread and flash straight through ODIN, or do I need to follow another guide?
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.

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...
https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487
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.

Do you have a link by chance to the files? Thanks
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?
i flashed the tmobile firmware and after its all dont i boots up does an update and then boots with all the sprint stuff still

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".
