Where I can get this app "Network"?

Some of those steps are placebo, and unnecessary. That will only get you 1x internet, and dependent on your location you may/may never get 3g to work they've been blocking off more cities from flashed phones from getting 3g..

[Q] US Cellular Galaxy SIII (SCH-R530U) on T-Mobile network

I ordered a Samsung Galaxy SIII (US-Cellular) on ebay and tried to follow the instructions below:
1. Type *#197328640# and it brings up the factory service menu
2. Select (1) UMTS
3. Select (1)Debug Screen
4. Select (8) Phone Control
5. Select (6)Network lock
6. Inside the Network lock menu, Pick option (3) Perso SHA256 off, Passed that is a screen that says something like "no options in this menu, current command is 11863", Wait for 30-60 secs, from there hit the menu button on bottom left of phone to bring up options, Select "Back".
7. The last command should have brought you back into the Network Lock menu, at the bottom is (4) NW Lock NV Data Initialize, Select it. You might be asked a saftey are you sure, some people not, after it begins that process wait a good 60 sec the reboot. Thats it! Phones Unlocked
Somehow the phone is not reacting on the USSD 'secret' codes. I can push the hash-button, but nothing happens. I found on a forum that I should root my phone. So I did through Odin. But superSU keeps crashing and I get the error: Security Notice, an attempt to access a secure area...
I don't really need a rooted phone, would be nice, but I would like to use USSD codes, like *#06# for example.

R530 is CDMA based and might not function correctly on TMo.
Also, USSD codes only work on TW-Based ROMs or stock. Root should have no bearing.

What you are trying to do is unlock the phone from US Cellular to use on T-Mo. If that's the case, you will have to downgrade the firmware to Android version 4.1.1. This does not require Rooting. You will see appropriate firmware on SamMobile.com. Try the same process after the downgrade.
Don't try the downgrade if you are on android 4.3. It will Hard Brick your phone.

switch on gsm?

Hi
I have a s6 edge from us cellular (cdma) is there any way to turn on the option for gsm as the only option i have in settings is LTE/CDMA.
Im rooted, but now I'm stuck.
Thanks

Google is your friend , i googled gsm unlock us cellular s6
Copied from there teamuscellular dot com
ayfi18 May 2015
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

Network lock menu from service mode?

Does anyone know how to get to the network lock from the service more for a sm910a?
i bought a unlock code from the celluar unlock.net..failed...didnt get any PUK error so all good there
ive tried numerious ways of entering the defreeze code and call that still failed... now they want me to do a factory reset and i dont want to do that just yet...
Ive done the non att sim trick...ive done
The following code brought up the network unlock prompt #7465625*638*# tells me unlock cone is sucessful
im trying to get to the network lock function through the service menu. Ive tried :
· Dial *#197328640#
· Press the Menu > Back > Menu
· Open the Key input and enter 1, then press OK
· Press Menu > Back
· Press UMTS > Debug Screen > Phone Control > Network Lock
· Press Options > Perso SHA256 OFF
· Press Menu > Back
· Press COMMON > NW Lock NV Data INITIALLIZ
· Your Samsung Galaxy Note 3 is now SIM unlocked
None of that above gets me there:
This takes me to the debug screen but from there I cant get to the network lock:
Do the same for *#197328640#. That will open the Debug Screen.
service mode *#27663368378#
*#6328378#
One thing I havent tried is because the phone is ATT but I have it on a Straight Talk SIM for the BYOP is to go into the APN settings and switch it from the Straight talk APN settings to the ATT Nextgenphone option and then prompt to do the sim there... NEVERMIND DID THAT AND IT FAILED
Any ideas guys??
Ive read place online to unlock it via usb cable but it says it wipes the data so im wondering how that works
might have to see if there is any option for KIES.....
.....no wonder why people already buy them unlocked...

hello i have a s8 edge how can i get access on network lock menu?

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?

Thread closed as there is already a copy in General and that is where it belongs.
