Anyone interested in unlocking their S6 it's fairly simple. Root and activate the hidden menu (directions are in xda verizon thread) and from the menu you can enable GSM. I have fully working voice,text and edge/LTE data. I have only tested on T-mobile
GUIDE TO GSM UNLOCK S6:
* Root Phone (Use Ping Pong root)
* Enable service menu
* Insert GSM SIM card
* Dial *#27663368378# -This will put you in service mode
* - UE Settings & Info
- Settings
- Protocol
- NAS
- Network Control
- Band Selection
* Make these selections above
* *Make sure you use the more button in the upper right corner to go back if needed(Back Key on phone will exit menu)
* Choose choice 7 “LTE/GSM MODE ONLY”
* Reboot
* Go to settings/Wireless & networks/more and it will allow you to add the correct APN
* Change preferred network type to LTE
Let me know if you need clarification. I don’t have the phone in front of me currently but am pretty certain that is everything

IOTHiddenMenu (USB Settings, LTE Settings, Test Mode, Dialer codes, etc)

Most noteworthy edits include LTE only mode, LTE/CDMA mode(no 3G) and NV BACKUP/RESTORE. Nice little all-in-one shortcut for most of the hidden menus on this device.
If there is another thread on this in the Sprint Galaxy S III forums I apologize. Just going to outline this menu which is found on stock Sprint GS3 Touchwiz roms.
Getting Started
You can use Any Cut, Better Cut, Nova Launcher etc etc to make a shortcut to this menu.
1. Better Cut > New ShortCut > No > All Activities > IOTHiddenMenu(first one listed).
2. Any Cut > ?
3. Nova Launcher > Long press on home screen > Shortcuts > Activities > Scroll to IOTHiddenMenu and click it to expand > Scroll down to the first IOTHiddenMenu in that list(under GPSCLRX)
Now we can open our new shortcut and you should see the following screen...
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
USBSetting Menu
This menu switches the phone's USB mode when connected to a computer.
MTP (Media Transfer Protocol; device shows up as USB drive)
MTP + ADB (default setting; should be self-explanatory)
PTP (Picture Transfer Protocol; device shows up as camera)
PTP + ADB (should be self-explanatory)
RMNET + DM + MODEM (RMNet = USB virtual Ethernet framework; DM = Diagnostic Mode; Modem = self-explanatory)
DM + MODEM + ADB (self-explanatory) (best setting when using QPST/QXDM/etc)
LTE Mode Menu
I do not have LTE in my area yet. Could anyone detail what some of the options below do exactly? I'm sure one is for LTE only.
TestMode Menu > CDMA > COMMON > NEXT PAGE > NEXT PAGE > PREF MODE SET may be the better alternative to this.
LTE Service Forced
Enable LTE Mode
Enable GLOBAL Mode
Enable CDMA Mode (default)
TestMode Menu
1. UMTS
UMTS > COMMON > NV REBUILD (NV REBUILD, NV BACKUP, NV RESTORE)
Everything else under UMTS either doesn't work.. or isn't worth messing with.
2. CDMA
CDMA > COMMON > NEXT PAGE > NEXT PAGE > PREF MODE SET (CDMA/EVDO/LTE, GSM/WCDMA, LTE ONLY, CDMA/LTE, CDMA ONLY, EVDO ONLY)
Everything else under CDMA either doesn't work.. or isn't worth messing with.
3. LTE
Nothing of interest.. just displays LTE debug status.
4. SIM
SIM > CHECK NV (Helps identify possible incorrect settings. Displays current PREF MODE. NV should be set under RTRE Config.)
Not worth messing with anything else in here.
5. run EFS SYNC()
Doesn't do anything.
There are lots of other options in here to mess with but most are broken, not supported or just really not worth messing with. All the MSL settings for example... no matter what.. I can't seem to read/write a new MSL via Test Mode. CDMA > CONTROL > MSL Edit has broken my MSL. *Update* Fixed MSL. I also messed up my EFS playing with the wrong stuff. I was able to recover.. but BE CAREFUL!!

The ##DEBUG# Menu includes the LTE Engineering information screen, which is the only place to find the proper signal strength (RSRP) and signal quality (RSRQ) of a live LTE connection.
I was playing with that and tried Korea mode think it would put the phone in Korean
Disappointingly it didn't now I can't connect to sprint 3g

run your NV RESTORE... TestMode > UMTS > COMMON > NV REBUILD > NV RESTORE. Make sure you hit the RESTORE setting and not Rebuild/Backup. The last thing you want to do is create a backup of bad nv settings(such as nv settings all being set for Korea mode). After you hit RESTORE the phone should reboot within a few seconds... wait it out. Your phone should now be unprovisioned... so it should try to OTA and that's that. If for some reason the "sktelecom" settings are still set... try running NV RESTORE one more time. If it STILL isn't fixed after that.. let me know. There are a few things we can do. Last night I messed my NV and EFS up pretty bad(sorta on purpose lol) but I was able to recover from everything. Even Korea mode.
Thanks man it worked perfectly
I tried updating profile and it did restore my username but not my 3g
You saved me a whole lot of time talking to sprint customer service bots

prime glad to see you have this phone. I follow your work on previous phones
I'm getting mine in a few days.
Question:
How do I backup NV? Where does it back up the items to? Internal memory?
Is it the same as backing up. NV 1192, 465, 466, and 1194?

hmm good question. to be honest im not sure where it backs up the files. pretty sure theyd still be in NV somewhere.
what you should do is connect gs3 to qxdm.. send 16-digit pass(same as epic/e4gt/etc).. then close qxdm and open up QPST EFS Explorer. All NV items will be unlocked in NVM > NUM. i think thats the folder anyway.. doing this all from memory. but ya... 1192 etc will now be viewable in EFS EXP when you send pw in QXDM first. No more "denied access" in CDMA WS
@auto
Have you figured out LTE is simply a MAC ID authentication?
Can we change LTE Macs and be connected like WIMAX?
Was going to do this as well
But the first 2 posts after the op's were my exact motivation in changing my mind. I had a feeling people would b ****n there **** up playin in it lol. Nevertheless, nice job OP, looks sharp. Well detailed too
anyone know where the settings are for MMS?
I'm trying to figure out how to send MMS on MetroPCS. on the Evo's I used a APN method, but apparently ICS doesn't allow 3rd party apps to write to APN. so I'm trying to enter the values manually. got into the DATA menu, entered a couple of the values, but a few other other values from that APN file are nowhere to be found in the DATA menu...and QPST refuses to see my phone?
any info on this would be great!
USCC
autoprime I have a USCC phone and have had no luck backing up the IMEI using the conventional QPST method. I have been searching Sprints info because some have had a similar problem.
When I try QPST it stops at 16% and says: "Roaming Lists could not be read".
Tried multiple times no luck.
I made a short cut to my hidden menus and everything looks to be the same as the OP.
My IMEI is currently fine.
That being the case is there a way to make a good backup now and restore it if things go bad? If this is possible can the backup be accessed and stored on a pc?
My goal is to find a way to back up the IMEI for myself and other USCC sg3 users. Any help would be very appreciated.

Which QPST program exactly is giving you this error? Also, random question for you... do the USCC Samsung devices have a 16 digit password that's used in QXDM? All Verizon Samsung's share the same password.. all Sprint Samsung's share the same password. You guys are kinda similar to Verizon's right.. same radio and all? so you know if 2010031619780721 works? Do you have QXDM or CDMA WS installed? Need to be able to send that password to the phone to fully unlock. then we'll work on backing up IMEI.

Are you referring to the NV RESTORE TestMode options? If so, I know of no current method to save that backup to a PC.
The TestMode NV RESTORE option should be pretty solid... if your phone boots.. you should be able to get to that menu. Same would be needed to get to QPST(booting phone).
So get back to me on which QPST app you're trying.. and what exactly is giving you the error... as well as any info on a 16 digit QXDM password.
Hey autoprime, i changed the korea mode on my phone before ever reading your warning. I have no data connection unless im on WiFi. Is it related to my change, if so do you or anyone have any idea how to fix it. Please. Im on freezas jelly bean leak lih

sorry for the delay in response. i assume you got this fixed?
Post #6 on the first page of this thread has a fix if you messed with korea mode. you may need to go back to ICS for this instead of Jellybean.
ATT: NAM BLOCK;
the Mobile Object Model (MOM) can be categorized as PRL and NAM, with the NAM blocks existing as several different types. For example, the MDN NAM block holds the directory number for calling the mobile. The CDMA NAM block holds parameters used when the mobile is operating in the PCS spectrum. The Dual Mode NAM block holds parameters used by a PCS or CDMA mobile while it is being used in the CDMA/analog spectrum. The IMSI_T block holds the true IMSI of the mobile station
hope this helps.

To get to the APNs on ICS, use Titanium Backup to make the APN Backup and Restore app a system app, reboot, then in APN Backup and Restore, check the box to bypass ICS check. You should be good to go.

OMG, you have saved my sanity with this post! I've been pretty good at flashing and programming my family's phones and some for friends but most of those have been HTC units. I didn't think twice when I got a killer deal on a couple of 32GB GSIII's but trying to program these for our service has just about had me sticking my head in the oven more than once. One of the issues was that it seemed to depend on the handset's mood as to whether or not it would accept a code input via the keypad. I didn't even think of using a launcher to create a master shortcut like you have here. I'm still not quite there as far as getting these things programmed the way I want them but this post cut my irritation factor in half! Having said that, I'm still seriously considering tossing somebody a few bucks if they'd just do these for me. I love figuring things out and working on things like this as great puzzles but the hours I've put into these so far have kept me from getting actual work done. Are Samsungs always 50% hellspawns to work with?
Anyway, thanks again and thanks to everyone else who has posted great info on these phones. Part of me really wants to get a GalaxyNote II but another part of me is threatening suicide if I even think about wanting to program one!
Sprint GS3 CDMA. (SPH-L710) running android 4.1.1 and it is rooted and has CWM installed.
better cut 3.3 can not make a shortcut to the UI screens as only apps and widgets go there now since we are ICS and JB
what app to use?
or can i access the hiddenmenu another way?
i guess we sprint users dont need the shortcut as that menu for "USB Settings" is already there
##3424# lets me see that menu and i can easily select MTP, ADB and DB and all the rest.
so this isnt a problem anymore
thanks

[Q] Do not select LTE on Samsung GT-I9195

Greetings to all. There is a Samsung GT-I9195 Galaxy S4 Mini LTE, operator MTS, sim with support for 4G (tested on another phone - LTE appears at once), the firmware 4.4.2, item selection LTE / WCDMA / GSM in the Settings menu is selected, but the phone in any does not want to catch 4G.
Also there is a strange feature in the service menu, in which I go through the program Advanced Signal Status (incidentally a good substitute command * # * # 4636 # * # * which is closed in the latest firmware), do not select LTE only, not selected EvDO only .
Can someone tell me what is the problem and how to fix it?
Try flashing a stock ROM again.
install different firmware was 4.2.2 and 4.4.2, and the result of the same everywhere, do not select LTE only, not selected EvDO only

Is there a way to unlock 5.1.1. OH1?

I already have root and have tried idones app to unlock, but for some reason, the unlock seems not to be working. The app says the phone is unlocked but when I insert a GSM sim card into the phone, it doesn't get any signal and the hands free activation loops. I was advised to go into settings -> mobile networks -> GSM, but the mobile networks setting disappears when I put in a GSM sim. It comes back if I put my Sprint sim is put back in. I also select GSM on that while my Sprint sim is in but when I take it out, that menu disappears. Is my phone unlocked or is it still locked? If its still locked, what steps can I take to unlock it given my current build and android version?
Idone should b able to help . Go to dialer, dial *#0011# ,
then in service mode press menu > back , then press menu > key input and type "Q" and press enter.
Then press menu > key input and type "0000" thats zero , 4 times .
The rest im copy n pasting from "jayfi" post iver at the us cellular forum
* - UE Settings & Info
- Settings
- Protocol
- NAS
- Network Control
- Band Selection
* Make these selections above
* *Make sure you use the more button in the upper right corner to go back if needed(Back Key on phone will exit menu)
* Choose choice 7 “LTE/GSM MODE ONLY”
* Reboot
* Go to settings/Wireless & networks/more and it will allow you to add the correct APN
* Change preferred network type to LTE
Let me know if you need clarification. I don’t have the phone in front of me currently but am pretty certain that is everything.
^^ after ding this itll go straigbg to gsm connection and bypass the cdma network. Let me know if you need help.
I have done all the steps up to 0000
After all those steps, the Service Mode Menu still looks the same, how do I get to the "UE Settings and Info"? It's not in my settings menu
Sent you a shortcut in pm . Let me know if u need help .
Can this work for the l720

Fix for VS986 dropping down from 4G LTE to 3G/H+

I've been working on a fix since a long time now. If you are in SD community then you prolly know me. Anyway I was able to fix this on two of my phones and it's now working fine. I tested for 12 hours now. I'll also tell you in the end what problems I'm seeing. I'm also working on a fix for that.
I noticed that a service is started when the fallback happens but if I kill that service the network also dies. But if you follow the below method it safely starts a new service which kills the one that's responsible for killing the 4G/LTE
1. Upgrade your phone to 13B firmware
2. Root 13B
3. Now download Shortcut Master lite app from play store.
4. Now add these shortcuts to your favorites in the "Shortcut Master lite app". You can search for "LTE" and click on search button
LTEBandSelection
LTETestMain
LTE System Selection
CDMAPreference
5. Now click on "LTEBandSelection" and enable all the bands
6. Save and reboot
7. You now need to enable your data and turn off your wifi. Make sure your phone is in Global mode (in settings >> Mobile networks >> System select)
8. After your phone is rebooted open "Shortcut Master lite" app.
9. Now tap on LTETestMain
10. Select Click on CDMA preference.
Now choose Band preference and select "any"
P_REV_Preference ---> "MOB_P_REV 3
This is important.. EVDO Revision --> Rev A
11. "LTE Connect w/o IMS PDN" must be checked
12. Now go back to your main menu in shortcut master lit app
13. This step is very important. Changing the timeout is important. Tap on LTE System Selection
Except "Scan duration" add a couple zeros to all the other timers. For eg: T_mpsr timer (Min) is 200
The fallback timer will reset itself after reboot. But don't worry the configuration is already updated with the new value. For some reasons the shortcut master lite app is not picking it up.
14. Now finally click on "CDMA preference" in the main menu and make sure it has the value you set in Step 10
At step 10 or 13 your network should go away and your phone should complain about "no network". That's fine. just ignore the message.
Now finally reboot your phone. That's it. You should now have 4G LTE and it won't fallback to 3G or H+
The only problem is when I'm on a call my 4G LTE is dropped to 3G/H+. But after I hang up it goes back to 4G LTE after 12 seconds. I don't know if it's an expected behavior. But I'm trying to see if there is a fix for that.
I tested this with Tmobile. Make sure your APN settings are correct.
Thanks @motorhead_biker., you rock!!!
I am on rooted 11a, flashing stock back and then will go to 13b to try this out. Was waiting for this.....
Isn't this thread a duplicate of http://forum.xda-developers.com/verizon-g4/general/guide-fix-vs986-dropping-to-3g-h-4g-lte-t3272434? Can they be consolidated?

GSM network on CDMA Samsung Galaxy Tab S (SM-T807P)

Hi, I'm ready to donate to the user who can help me to get my local GSM carriers working in my used Samsung Galaxy Tab S 10.5 LTE.
It is pre-owned, clean IMEI (no financial problem nor blacklisted issue), and I can see the SPRINT user data everytime I flash the stock ROM (Sprint number, user Sprint email, etc). I'm running MM 6.0.1
I have flashed stock ROM > rooted (CF-Auto-Root) > unlocked and debranded (idoneapps app) > flashed custom recovery (TWRP).
After that I have tested all the setting I could find here and in ohter websites including:
- gsm.zip patch (installed but not working)
- DFS tools (new GMS/UMTS/LTE bands enabled succesfully!)
- Enabling Global Mode on Service Mode (nothing changes)
- Editing build.prop system file (nothing changes)
- Runing some adb commands (nothing changes)
Current situation is:
- Now I can see the new bands added (GFC Settings)
- There is not more the message "Connecting to netwok" on the top left corner
- APN configurad correctly
- The carrier signal icon is always empty
- I still can't set "GSM auto (PRL)" as the "Preferred network mode" under Radio Settings
- No internet connection at all (GSM/HSDPA/LTE)
Any solution for this?
