I am of need of some information. 3 days of bits and pieces here is where I'm at.
I rooted this phone with droids kernel and installed a few different roms only to find that I had a non locking GPS. So after several threads I found I needed to return to stock and get a lock. Here is where the problem started. I have never found a Cspire stock file for the SCH-R760 the best match I could find was a USC easy upgrade tool on samsung. Flashed the util and got a stock lock. After several buil.prop edits apn edits never could get data to work. SO I found a generic carriers stock FF24 total tar package posted by Mcadder on the USC site flashed it with odin and checked the efs clear to wipe out all the USC stuff. When I came out of the flash all device information was gone and prl was gone. So then I went into ##3282## changed all the information that I had to get voice text and prl back. So I'm now rooted with no data.
I need someone who is on Cspire to go into ##3282## and give me some information so hopefully I can get data back.
Also if anyone has a default build.prop for this phone Please post. I have asked in other post but not finding to many people with a Cspire SG2 that can help.
I can help

What specifics do you need from there. I see lots of information?
If you have this fixed already. Are you staying with the original load for this phone or did you find a ROM that works? I am wanting to flash my CSpire S2 and hope to find a jellybean load to work. I remember having trouble with the data on my S1 after flashing and went back to the original load.
Needed to close this. I got it all fixed and yes ,Using CodeName Android that was ported to USC then reported back to cspire.

Hey, I'm suffering from the same problem. Accidentally flashed a US Cellular ROM and now i have no data.
Can you post the steps you took to fix this?

Did flashing a us cellular custom ROM to your cspire Samsung galaxy s2 do this or did you lose your data by updating the firmware through us cellular? What I am asking is if it is safe to flash a custom ROM made for a us cellular galaxy s2 to my cspire galaxy s2??

It was caused by running the easy upgrade tool from Samsung, designed for US cellular . I personally run stuff for the Epic4g posted here.Some say it is not wise to do so because they aren't exactly the same,but I have had little issue running CM10,PA,AOKP,AOSP.

I'm currently new to the xda forums, so I applogize in advance if i am posting in the wrong thread. But I currently recieved a samsung sph-d710 that was on sprint from a freind. I currently have a samsung galaxy reverb from virgin mobile that currently has service, and I've been reading around different forums and faqs about flashing phones to other carriers and was wondering if there was any way i could get this phone to work with my virgin mobile account. I know that virgin mobile has had this phone on there service before(my mom has one). And also is it possible for me to somehow rip off the stock virgin mobile android os from her phone? I've browsed around and couldnt find any downloads for the stock virgin mobile os for the phone, so i think this may be the only way for me to get the os. Also how would i go about copying her os system? Do i need to root her phone and create a clockwork mod recovery of her phone, then somehow extract that file to my computer, then use some program to fully flash it over? I'm all very new to the flashing carriers, although i do have basic knowledge of rooting and running custom roms. Does flashing a sprint phone to virgin have to be done with a special program on the computer(i have cdma workshop, but have no clue how to use it). And also even if i was able to flash the phone to virgin mobile, wont the esn still be registered as a sprint phone? Or is the esn device type specific? Also what is prl? Do they need to be updated? I guess in general i'm asking alot of question, but what are the steps to flashing the phone over, what all needs to be changed? If anyone can help answer one or all of these questions i would be forever greatful. Also pointing me to some tutorials would be greatly appreciated :fingers-crossed:
Hey, gang. I have a friend in a different state who has a Verizon Galaxy Tab 2, it is a SCH-i705, and the firmware is 1705VRBMI1. He doesn't have mobile service on it, but would be interested in using it over WiFi for stuff, He did a factory reset a while back(without its being on Verizon's network), and has been experienceing some problems with WiFi connectivity and some apps.
I am hoping to help him restore his Tab to stock. I have already flashed several of mines and my friends' devices, but I haven't worked on anything this old before. I have tried to find a suitable thread, but every one I've seen seems to contain outdated or disputed information.
What I'd like to know is:
- Can I sideload the stock 1705VRBMI1 firmware using Odin, and if so, where can I find it?
-Is 1705VRBMI1 the latest official firmware for this device?
-Will his not being connected to a mobile network prevent us from restoring his device to stock?
-Is there working root/recovery etc. for this firmware? Where?
If I am missing a very obvious thread about this somewhere please feel free to mock me mercilessly. And thanks in advance.
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.
OK
I´ve got one s5 here in Cuba, it is from boost / sprint.
Ithas not been a problem for me to unlock it and make it work on GSM 2G, here.
but I have few issues which I would like to solve.
I cant find an option to import the contacts from the Sim card, so, my sim card contacts are just ignored by the phone, not eveb there is a choice for showing the sim contacts together with the phone contacts.
There are some USSD codes which I cant use at all
APN changing it is another issue, I know this is being addresses in the forum.
Phone is running 6.0.1 PE1 firmware, I can easily root using cf-autoroot.
is there a generic ROM, from international model like g900F, which I can just install to the sprint phone thus removing all the sprint stuff.
I know there is a cyanogen mod 13 out there, but I would like to stick to as close as possible to stock touchwiz roms.
Any suggestions / thoughts / ideas ?
there is an apn manager app called (oddly enough ) APNManager, its available in the play store and its icon is a hedgehog. It does the work for you regarding apns. As far as a stock feeling unbranded ROM, you can TWRP flash whatever ROM you like as the functionality wont be impeded as long as you dont flash the modem for a different model on it. I personally recommend MOAR 7.0 and use titanium backup to backup and delete anything "sprinty". For that matter , you could just use titanium backup to backup then uninstall that same "sprinty" stuff on your current ROM
