1.)Remove third party potential threating apps just to be sure.
2.)Always make sure the phones up to date on the latest firmware.
3.)The next step is to go to the dialer ##72786# that forces the phone to reactivate.
4.)Next step go back to the dialer and dial ##3282#
4.2)Go to edit
4.3)Then type 000000
4.4)Then go to LTE
4.5)Then go to band 41 that is enabled and uncheck to disable.
4.6)Then go to band 25 that is enabled and uncheck to disable.
4.7)Then go to band 41PCII that is enabled and uncheck to disable.
5.)Reboot the phone don't expect full LTE service yet there are still some more steps...
6.)Go to settings find VOLTE and enable. Search VOLTE in the search bar to enable it.Swipe right on the button to turn it on. New icon will pop up at the top of the phone if done correctly.
7.)Then go back to the dialer and type ##3282#
7.2)Go to edit
7.3)Then type 000000 again
7.4)Then LTE again
7.5)Then go to band priority
7.6 & 7.7)Set both bands 41 and 25 to the bottom of the list by typing the number 17 on band 25 and 18 on band 41 and that pushes them down the list. Make sure band 26 is set to 1 on the priority list.
7.8)Then turn off your phone and turn it back on.
This fix is broken from a network reset or ##72786# update or Samsung software update. So reapply the fix after each update or network reset

The Sprint side of this issue. https://forum.xda-developers.com/s10-plus/help/galaxy-s10-models-lte-issues-t3923109 I am not sure if this well help other carriers.
It works but
I'm on sprint and it Definitely helps with the signal, but I lost lte+. I have been not getting texts unless I send a text, then they all start flooding in. Had this problem since day 1 and this didn't help the problem with texts

Good luck read up
don' work in note10+
i think OP should change the threads' titles reared towards rural people. people take your advice and use it for other ways.
you are spreading wrong info. do you know that you can roam on tmobile lte? it is better than having no lte or just ehrpd.
stop spreading nonsense

So there is a setting burried down in Settings, More settings...Mobile Network. There are two options. CDMA and CDMA/LTE/EVDO. The CDMA option was selected stock. I have changed to the CDMA/LTE/EVDO option. Does this mean I will see/connect to LTE towers as they start lighting up in Atlanta-metro next week?
Or will I have to wait for some push update from Spring/Samsung that adds another connection type (e.g. Wifi, Bluetooth, etc...) to the mix?
The reason I care is that I don't want to root my phone until after I know it will work with LTE so I can ignore the sprint updates after that.
Help?
Hi EPST and reprogramming your phone, a comprehensive guide
I see a lot of posts in dev threads like "i flashed your rom now my signal/data is gone" so i decided to create this guide to help relieve unnecessary posts. Hope it helps
An introduction to EPST
Epst is a application that sprint uses to activate/program a phone. It read/writes to the NAM of your phone.NAM is an acronym for Numeric Assignment Module and is the place in TDMA/CDMA equipment where your phone number, ESN, system information and data settings live. In the old days we programmed handsets by hand, now it is usually done OTA (much is preset, a little is manually entered, data provisioning is truly OTA). It has many uses but this guide will concentrate on the data portion of epst. Here are the 3 codes that we will be using:
##3282# (data)
##72786# (scrtn)
##786# (reverse logistics support)
Keep in mind you will need your msl either from sprint (its really easy to get), or msl reader from the maket (root required)
##3282# (Data)
{
"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"
}
The Data menu is broken down into 6 menus and usb charging selection.
1. Data Profile: This is where you can setup multiple data profiles (not sure why you would to) and contains your sprint username and other info on your data profile.
2. Evdo: Two menus here DDTM and preferred mode. DDTM is an option to where if you are downloading over your 3g/1x it will send calls to voice mail. It can be useful if you are trying to download a large file over 3g and don't want it to be interrupted. Preferred mode is exactly that... your network preferred mode. There are several settings there all of which are safe to use. Mine is set to cdma hdr only because i have no lte in my area. In theory it should save a little battery life by not scanning for lte.
3. Advanced: This menu contains a lot of important info. From your esn/meid to toggling lte.
There a few settings in here you can tweak to possibly benefit from.
A. Slot Cycle Index (SCI): This determines how often a handset polls the network for coverage and incoming packets. The default value is 2. A "Slot" is 1.28 seconds and doubles with each incremental change from 0 to 7 (0=1.28, 1=2.56, 2=5.12 seconds, etc). setting a handset to poll more often may use noticeably more battery if coverage is thin or lacking.
B. ACCOLC (Access Overload Class): This code determines your priority to make and receive calls on the network. Higher the number, lower the priority. Lower the number, higher the priority. Emergency Services reserves 0 + 1 (please do not use these) leaving your choices to 2-9.
C.Removing the Sprint Proxy
1. With MSL in hand, go to the Phone app and dial ##3282#
2. Click Edit Mode
3. Your "Password" is your Phone's MSL, enter it here.
4. Click Advanced
5. Scroll down to RTSP/HTTP Setting
6. Change RTSP proxy IP to 0.0.0.0 or You can leave this blank if you like
7. Change RTSP proxy Port to 0 (Zero)
8. HTTP proxy IP to 0.0.0.0 or You could leave this blank if you like
9. HTTP proxy port to 0 (Zero)
10.Once complete, back out to the home screen and enjoy Downloads and a .20- .60 mbps increase in 3G speeds!
It may not hurt to verify the settings are in place by following steps 1 through 5 again, if you're OCD. Removing this proxy removes at least one or more hops in between you and your connection destination, possibly increasing your WAN connection speed via 2G/3G/4G and Wi-Fi. As always, use at your own risk and take a screen shot of your original settings.
D. Improve CDMA Call Sound Quality via a Codec Change:
There are a few important things to note. This adjustment changes the Codec used to compress the voices of you and your caller across the Cell Network using EVRC-B which is an updated revision to the current CDMA standard EVRC. It has been noted in a few places, that making this change CAN effect your ability to make outbound calls in some roaming situations, including over Network extenders like the AirRave. As always, YMMV and I STRONGLY recommend that you both test this change in your normal use environments as well as keep a general idea of these instructions handy in the event you need to revert to the default settings in an emergency. As always, YOU and YOU ALONE are FULLY responsible for changes to any handset in which these and any modifications are made.
1. With MSL in hand, go to the Phone app and dial ##3282#
2. Click Edit Mode
3. Your "Password" is your Phone's MSL, enter it here.
4. Click Advanced
5. Scroll down the list and note the entries for EVRC-B, Home Orig, and Roam Orig.
6. Change EVRC-B to "Enable"
7. Change Home Orig and Roam Orig to "EVRC-B"
8. Hit Menu, and select "Commit Modifications"
9. Your phone will prompt you to click ok to restart or it will restart automatically.
To reverse the changes, repeat all of the above steps except change the following.
6. Change EVRC-B to "Disable"
7. Change Home Orig and Roam Orig to "EVRC"
Click to learn more about EVRC and EVRC-B
4. DSS:Not sure if these really need to be messed with unless you have flashed to another carrier...
5. LTE Record Various logs and scan rates for LTE safe to adjust...
6. PDN Setting I only found one document which seemed to pertain to this Here There are 3 sub menus internet, ota, and pam (phone as modem?). If anyone knows more about this fell free to chime in. :good:
##72786# (SCTRN)
This menu contains 4 sections containing your MDN, MSID, M.IP Custom Profile1-NAI and AAA shared secret password. All of these are unique to your data profile and should never change. The ##code is used to reset these 4 items to re-provision your phone without wiping any data.
##786# (Hard Reset)
This menu contains a lot of the same info as the previous codes with a little extra. It is used for the quintessential "hard reset". This will completely wipe data/app, your internal sd, and NAM so your phone can be re-provisioned.
FAQ SECTION
Note: I do not fully understand how or why the NAM section of your phone becomes corrupt but is does. I have never had to call sprint to have them fix my data so i hope this helps.
Q. Help im stuck on 1x/2g.
Q. I just flashed your rom now i have no signal help!
Q. My data speeds really suck lately anyone else?
Note: All these fixes must be preformed on a stock or stock based rom with epst support and make sure you are in a known good signal area
A. These are all very common questions i have seen around here in the past years and are all very easy to fix... process below.
Whenever i have data issues whether it be stuck on 1x, no data/signal, or slow data, I always follow the following steps...
1. ill just do a profile update and see if that helps.
2. If that doesn't help this is my next step.
Enter Dialer
##3282#
select edit and enter MSL
select data profile
select menu and select Restore
reboot and update profile
3.Still no worky?
Enter Dialer:
##72786#
select edit and enter MSL
select menu and then Reset
After phone goes through "hands free activation" and your back at your dialer, enter this:
##3282#
select edit and enter MSL
select data profile
select menu and select Restore
After your rebooted and back at your home screen go into settings/system updates/ and update your profile.
4. This is your last step before calling sprint (which i have never had to, this has always worked for me).
THIS WILL WIPE EVERYTHING IN DATA/APP AS WELL AS YOUR INTERNAL SD! YOU HAVE BEEN WARNED SO MAKE A BACKUP
Enter Dialer
##786#
select menu and select reset
enter msl and select ok
After phone goes through "hands free activation" go into settings/system updates/ and update your profile and you should be set
This guide is a WIP, and yes i know most of this information is already in some thread buried somewhere but I thought a little consolidation was in order. Maybe we can get data questions in here and there wont be 4 pages of someone trying to figure out why their data wont work in a dev thread.:good:
Also this is my first attempt at a guide...go easy on me.
Prl Information
PRL INFORMATION AND UPDATING
Thank you Digiblur for letting me kang some of your OP. I really appreciate it. Go thank this guy NAOWZ!
Take a moment and read this article before reading any further: What is a PRL?
PRL Series - Acct- Device
25xxx = Residential acct - LTE/800SMR
24xxx = Business acct (some 3G roaming added) - LTE/800SMR
55xxx = Residential acct - worldphone LTE/800SMR
56xxx = Corporate acct (VZW 3G roaming) - worldphone LTE/800SMR
16xxx = Corporate acct (VZW 3G roaming) - LTE/800SMR
11xxx = Corporate acct (VZW 3G roaming) - no LTE/no 800SMR
12xxx = Corporate acct (VZW 3G roaming) - no LTE/low priority 800SMR
60xxx = Residential acct - no LTE/no 800SMR
21xxx = Residential acct - no LTE/low priority 800SMR
51xxx = iPhone5 - low priority 800SMR
800 SMR Enabled PRLs/Areas
xxx13 - DFW, Chicago, Baltimore, North CA, Atlanta, Boston, Houston, Indianapolis, Kansas City, New Mexico, New York, Orlando, San Antonio and Southern California
PRL Change Logs and Full Analysis' can be found on this website:
www.batonrougebroadband.info This is Digiblurs site the guy is full of info
PRL 00001, 00002, 00003, and 01337 are modded PRLs that force your phone to use Verizon's network for voice and 3G Prl 15094, 15096, 17098 are PRLs that force you to use US Cellular's network for voice and 3G. Use these for TESTING purposes only. I do not recommend or condone using them 100% of the time. You will not be able to determine when you are roaming. You won't even be able to tell if you roaming internationally!! There is a 300mb data cap and other minute based roaming caps with Sprint. Myself or this website are NOT responsible if you break your Terms of Service and get your contract terminated. Discussions about how to get your contract terminated using these non-Sprint PRLs will not be tolerated and will be deleted. If Verizon/USCC works for you and Sprint's service does not, then you need purchase Verizon/USCC service.
Common PRL Myths
1. A PRL is not a list of towers. It's a list of cell phone systems that your phone searches for.
2. It will not make your phone connect to different Sprint 3G towers.
3. It will not give you better Sprint PCS band 3G or 1X coverage.
4. It will not give you better LTE coverage.
5. An update is not required for new cellular sites.
6. The only time a PRL update will give you better native Sprint coverage is when 800mhz SMR (BC10) support is added and enabled in your area.
7. You can not use AT&T, VZW, or US Cellular LTE with a use of a different PRL
8. Don't believe the nonsense and lies that a Sprint rep will tell you about PRLs (they were never trained on PRLs and only go by rumors and hearsay instead of facts)
Prl updating without a pc.
NOTE: This will only work on sense roms with epst support.
On device prl update is now possible. I would like to thank rulingczar for some help looking in the right place. All you have to do is edit 1 line in build.prop.
How to change the build.prop:
There are a few ways to change build.prop. The easiest imo is to use an app like kernel tuner to change it. KT even has a nice backup and restore option. You could also take your favorite file explorer and navigate to /system and open build.prop as text and edit there. If you are adb savvy then you could pull the file, edit it with a program like notepad++, and push it back to your device with proper permissions.

1 .Reboot and let the system fully load (or there will be lag in Epst) and enter dialer.
2. Enter ##778# and choose edit. Enter MSL and choose prl.
3. Select update prl and select a prl from your sd card.
4. Select menu in the upper right corner and commit modifications.
5. Epst will reboot the device and the prl should be applied.
6. It is always a good idea to update your profile after a prl change. Enjoy!

They also give it to you in an email if you do an esn swap (change phones) online. They also give directions how to program your phone in the e mail. They like to refer to it as "a six digit number" lol.

As I recall, going into the individual PDN items on that list while in edit mode will delete individual entries if they are accidentally selected and no info in entered in the field ie you select the field to edit and you can't cancel out to get the data previously populated in that field.
Has anyone successfully backed up and restored CDMA "APN"s? Even looking under the hidden function "CDMA APNs" shows no actual APNs in the traditional GSM sense.
They aren't kept in the apns Conf. Look in mms_config.xml in the mms.apk.
There is a program that can decompile apks to actual source code not smali. I would like to have a look through the epst.apk and see how it works. May be able to get more features.

That would be awesome, im just a union electrician, and dont know too much about java... Speaking of more features im attaching a copy of epst from android 2.1 eclair. It had the feature to change prl's on the fly via handset ##PRL#. It was ported to 2.2 and 2.3. I dont think anyone really tried to get it going on ICS which would be very nice. I would definitely appreciate if anyone got it to work...
Well on the fly prl changing is once again possible on the info bar rom by newtoroot
This is on a us cellular prl. :thumbup:
Here is the epst apk:http://db.tt/Lghf8UVb
I haven't been able to get it to work but I only tried on viper rom. I'll try more later tonight...
Edit: forgot to mention the code is ##778# then enter your msl.

Hi, I am currently using the VZW Google Edition ROM 5.9 and have service and WiFi. My problem is it only connects to 3G, and not 4G. As advised, I have not gone into network settings, but I did open Phone Info and see that it is set to LTE/CDMA auto. Any reason I am not getting LTE?
Just a thought, but maybe you could check the APN settings and see if they are different than what you should have.

Thanks for the response. I am kind of new to this, where do I check the APN settings and how do I know what I should have? Thank you.
Do you have LTE coverage in your area? If so, can you use another phone/friend to double check if LTE is working? I only ask because we had LTE go out where we live.
Gir brings up a good point, I don't have 4G where I am (and probably won't for years!), but that may be simplest as long as they use the same network (although many carriers piggyback off the same network).
The APN settings should be under "Settings > More networks > Mobile networks > Access Point Names". On a stock ROM you have to get to the actual file through ADB, you should be able to see it if you have an aftermarket ROM. The settings for the APN will depend upon Verizon. Here is a good post with APN settings for Verizon, the first part is for Android.
Coverage could always be the issue as that has plagued me more times than not.
From the ROM thread:
Go into mobile network settings.
Verify that your CDMA subscription is set to RUIM and not NV.
For good measure go into the rest of the options and set it to CDMA/LTE, automatic, and allow data roaming.
Back out to your home screen.
Then go into Phone Info app.
Scroll to bottom and tap radio off.
Open the drop down list and select CDMA/LTE auto (PRL).
Turn the radio back on.
Reboot.
Upon reboot open Phone Info again.
Verify it is set to CDMA/LTE auto (PRL)
** you should have full service now * *
** if not * *
In Phone_Info(*#*#4636#*#*):
Try CDMA auto (PRL)
Then try CDMA/GSM/LTE
If those still don't work then your nv_data needs reset. The only way to do that is in the hidden menu dialer codes in a touchwiz-stocktype rom
If you destroy your nv_data and cannot get data back via the above you need to (stop screwing with your network settings)flash back to a TW ROM, enable hidden menu, and do a NV data reset via dialer code. After doing that make sure your phone is not in modem mode under diag dialer code. Until I update this section Google is your friend. And it is available information, verified. Your lack of searching skills doesn't mean pester my inbox...
I do have LTE in my area, as I had 4G before I loaded the rom. I do not have an APN menu under mobile networks. Do you think it could help to dial *228 option 2 to update roaming? Or possibly a new 4G sim card?
Anything about updating I would research first and be wary of... A new SIM card could help, but I'm assuming it is not the problem. Did you make a NANDROID before you changed ROMs? You could then go back and see it you still got 4G to make it evident if your SIM card is the problem.
FIXED
Just needed a new sim card. Thanks guys. I appear to be receiving signal bars with my LTE on the GPE rom as well.
Try to send an SMS and get a can't send error message. Looking at SIM cards in Settings abd the SMS Messages is greyed out. Any ideas?
where are you based ?
i find if the radio band is set to USA the calls and text function are greyed out. leaving only data to work.
only if its set to Europe for me do calls texts and data all work together .
to change the band press on the dial pad *#*#4636#*#*
this will enable engineering settings.
press 'phone information'
top right press the '3 dots'
press 'select radio band'
then choose a band based on your location or play with them see which works best exit and try that.
redo the steps to change again.
if this doesnt work maybe check your network APN settings
for me im finding this phone a mess ,

My P9000 keeps crashing when I select radio band. I get the error stating "com.android.phone has stopped". Any solutions beyond soft-resetting?
How to Flash U Firmware On AT&T and Keep Volte & video calling and get lte band 17
So after Doing some looking around i found out how to get volte and video calling working,and enable band 17 on G930U. I dont take credit for this. i seen it on a different forum and just wanna make sure people know how to fix it.
For starters if you dont have g930u or dont know what it is. heres a great thread about it with easy to follow instructions http://forum.xda-developers.com/att-galaxy-s7/how-to/xda-community-love-g930u-t3415875
Okay so after you flash the U Firmware.
edit the others.xml in System/csc. Scroll to the bottom of the xml and change volte and video calling to TRUE. Save and then reboot. The options will be in settings and the video calling icon will be in the dialer.
and to re-enable band I7 Open the dial pad
Type: *#0011# to enter Service Mode (Be very careful with what you do here)
Note: You need to be rooted for this to work
Once in Service Mode, do the following:
Tap the menu button and tap Back
Tap the menu button again and select "Key Input" and enter an upper case Q and press OK
Tap the menu button again and select "Key Input" and enter 4 zeroes (0000) and press OK
Wait 5 - 15 seconds. You'll see the Main Menu
Choose option [2]: UE SETTING & INFO
Choose option [1]: SETTING
Choose option [1]: PROTOCOL
Choose option [2]: NAS
Choose option [1]: NETWORK CONTROL
Choose option [4]: BAND SELECTION
Choose option [4]: LTE Band Preference
Choose option [7]: LTE ALL (Or you can choose any band instead)
If you want to go back then tap the menu button and choose Back (Don't press the back key)
Once again guys i take no credit for any of this. ive just seen people looking for the information and decided to put it all together for you
I am just curious, what's the benefit of enabling B17 on the device given that AT&T has B12 MFBI enabled throughout its network?
Does this enable the enhanced LTE voice? When you go to About Device > Status does it show IMS registration status as "Registered"? None of the carrier specific features will work unless the IMS is registered on the AT&T network.

LOL, I know.
What I understand is that none of the carrier specific features will work unless the AT&T network registers your phone. They have certain models they will recognize on their network for those features. 930U is not one of those models.

You left out the part where root is required to modify a CSC in the system partition.

not where to be found those csc settings on a 930a with the latest pg9 Ota firmware
I am on the 930U firmware on my ATT&T S7. I can get to service mode, I am rooted, but can not get to the Main Menu. I have tried several times and it does not get past the opening page. Any suggestions?
I don't understand. Isn't G930U supposed to be used in US? If a band is used by a US carrier and supported by phone hardware, why firmware disable it?

Well, why does TMobile wifi calling work straight out of the box on the U firmware while AT&T's doesnt?

IMO this is because of the stupid AT&T policy, not because the phone does not support it.
AFAIK not being able to use band 17 is Samsung's problem right?

The S7 has wifi calling on the ATT branded rom. It's the stupid (or smart in a business sense) way they change things to their own proprietary format. If you want wifi calling then you have to buy their phone, not the U version.

Really? If G930U doesn't have wifi calling, why can T-Mobile users use wifi calling on G930U firmware?

That's what I'm saying it has wifi calling, but it does not work on the ATT network because they changed their rom for their wifi calling, the built in Wifi calling in the U rom does not work with ATT.
