3G fix for Thunderbolt

LTE is back online, please follow steps at the bottom of this post to get everything back in order.
*If you are in a 4G area it is advisable to make sure you switch to eHRPD to avoid bad hand offs between 4G and 3G as well as allowing simultaneous voice without hiccups. I noticed my GPS was not working last night so it is possible eHRPD settings will affect your gps or it could have just been due to the network issues.
As most are aware both the LTE network and eHPRD are down (a special version of 3G for the Thunderbolt only). To get 3G data back you just need to change your settings back to the normal 3G network. Here are the steps:
Dial ##778# and hit send
A pop-up window named EPST will show up giving you 2 choices: View Mode and Edit Mode. Pick: Edit Mode.
Enter the Password: 000000
Go down to Modem Settings and pick “Rev A“
You’ll want to choose enable and click OK, hit the menu button and then press “Commit Modifications.”
Restart your phone and you should see 3G is working
last step (may not be necessary)
dial *#*#4636#*#* go to phone info, then set preferred network type to CDMA auto (PRL)
I hope this helps anyone that is left in the dark by this outage.
If you are running a non-stock dialer or a rom that included a dialer it may prevent you from entering settings. Flash this zip to go back to stock dialer

For those that want instructions for after LTE is back on
These 2 steps will put you back on LTE and then put you back on the correct 3G for the Thunderbolt, when its back up.
dial *#*#4636#*#* to get LTE, go to phone info, set preferred network type to CDMA + LTE EvDo auto
Dial ##778# and hit send
A pop-up window named EPST will show up giving you 2 choices: View Mode and Edit Mode. Pick: Edit Mode.
Enter the Password: 000000
Go down to Modem Settings and pick “Rev A“
You’ll want to choose eHRPD and click OK, hit the menu button and then press “Commit Modifications.”

Isn't this selected by default? I changed it to "enabled" let it reboot, and 3G is back on.

By default we are setup for the eHPRD 3G network on the Thunderbolt because it allows faster switching between 4G and 3G. Since both network features are down you have to switch your settings to the 3G network used by all other Verizon phones.

eHRPD is the new 3g in thunderbolt I believe you need to select enable.

yea but in your instructions you said select eHPRD, which is already selected.

Yes enable, sorry I was too fast in typing out my instructions and goofed

one more step guys, if you are on auto cdma/lte settings, you might have to go in to
*#*#4636#*#* and select phone info and then select EVDO only to get 3g under preffered network settings.
It would be nice if you could add this to OP wakestrong. I think people in 4g area have cdma/lte auto option enabled so in the phone settings the phone is still trying to pick up the older cdma.

So this has worked for everyone? I tried this earlier with no luck and just did it again with no luck either :/

Look post above. You might have cdma/lte auto enabled under phone info menu so it is still searching for 4g and older 3g.

ITS NKD man Not NDK, lol.

technically if you would have waited it would have eventually gone to 3g but might have taken a while, but that option is just an easy way of doing it.

My thunderbolt worked on auto cdma/lte but this may cause less conflict.

Thanks a million! It worked. Good night, I was on 1x ever since I flashed the stock rom. I thought for a while it was an error on my part. Talk about bad timing.

I love all the nifty little tricks we find on the internet
Thanks OP.
First the PSN is down for a few days, and now Verizon's new network. Wth?

Yea I could see how that would be a stressful situation. Glad it worked out for you.

Force LTE only

Does anyone of you know the secret code to dial in the dialer to access the network settings. I remember using it once in my old android device and theres is an option for LTE only. In the setting the option is LTE/WCDMA/GSM therefore I can not force LTE only

Dial *#2263# and then click band selection then LTE then LTE all when you want to change back just click band selection then automatic

That did not work on my sm-g920f international version.
Must it be rooted?

No, it works without Root.
Go to the dialer and enter *#0011#.
Click on the menu icon on the top right and press Back.
Click on the menu icon on the top right again and press Key Input.
Type in Q and press okay
Then repeat step three, but enter 0000 this time. Wait until the Main Service Menu pops up (it can take up to 20 seconds).
Go to UE settings and Information -->Setting-->Protocol-->AS-->Frequency Lock-->LTE Cell Locking
Select the LTE band that you want your phone to lock into.
Reboot

It still doesn't work. Here is what I did:
Entered *#0011# in the dialer
Response Service Mode, Select STACK, STACK 1, STACK 2
Clicked on the more menu icon on the top right
Clicked Key Input
Entered Q and pressed OK
Clicked on the more menu icon on the top right
Clicked Key Input
Entered 0000 and pressed OK
The original menu did not change.
The device is an G920FXXU1AOE3 with Android 5.0.2
Without LTE it is going back to Amazon.

Sorry about the right and left confusion, that was unintentional. I did fixed that. Thanks!
Did you press "back" from the more icon before the Key Input?

Just after my last post the S6 totally stopped connecting. I wonder if it is one of the counterfeits I've been reading so much about. Anyway, the phone is on its way back to Amazon.
Thanks for your help.

Guys is there any way to force this silly phone to switch to lte? Menu 2263 doesn't work and tip above also doesn't work...
Wysłane z mojego SM-G920F przy użyciu Tapatalka

I have a feeling this may be my problem with my Galaxy s6 as well.
Doesn't anyone know how to force LTE then? Or just even how to switch between the options of LTE/GSM ect

I'm having the same issue with my international version of my S6 too, no possible way to force LTE only bands?

Same problem here. Only way for me is to to toggle WCDMA and Lte

2 ways to do this.
1. Root your phone and install Advance Signal Status in playstore. Once installed, open the app > go to Additional Info > Device Information > and look for Set Preferred Network Type dropdownlist. You can choose LTE from there.
2. You need Root + Xposed Framework. After installing Xposed, Download Intelli3g module and from there, you can toggle Fast And Slow Network Mode. Just be sure one of them is set to LTE only.

FyI Stock Latest firmwares will not allow you to change or modify the radio settings on your phone using service dial codes.

So Im going to bump this due to the fact i had ran into this problem exactly. I bought my s6 edge out right from the only store that would do that at the time which was wind mobile. wind your supposed to get 4g max is what the icon says but after using the Advance Signal Status apk with being rooted and all that showed to be working was 2g/3g everything else was n/a. **** you wind your a horrible company. Anyways after millions of dropped and echo filled calls that didnt drop or the turtle like so called high speed internet. i went to telus got a sim card and a plan and put in the sim card and i get a 3 g signal and the apk shows the same thing. i called tech support and this guy went above and beyond the usual script those idiots read over and over when they dont know what they actually do there. at the end of the call he says im sorry my coworker is saying if it was from wind you wont get lte on that phone with us. i had no way to choose lte through my phone settings and it was driving me crazy. so after a little research and a little playing around with the band selection by going *2263# first selection in the list. i tried going straight to lte only and it went over switched from 3g to 4g+ aka lte also verified by the advance signal status the only **** active was the lte section... so i thought yes i did it so i try a call and wtf immediately the phone would end the call every time and incoming went to voicmail every time. so i then started to try the different lte combos and to save someone time i ended up with the lte+cdma(prl) and after that it stayed with lte band and the phone calls work.
just because some tech support told you you cant run some sim cards on some phones unlocked or not because of frequency's of the carrier, but thats noy true and i proved that to my self today. have some patients and make sure you have a back up ready and waiting just in case at all times ive learned the hard way too many times saying this flash is a quickie im good lol nooope ...anyways i will also be getting a wind sim to work on the s4 wind says it cant be done but i say other wise i will post my findings on the appropriate pages.
i hope this helps some people

Samsung Note 10 Signal Fix Sprint (If Needed)

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#

First, I'd like to say thank you for this information. My phone was showing 1 bar and it now showing 3. Recently while in Costco, it took a long time for me to connect to a website and I had 0-1 bars, while my brother on his Galaxy S6 had full speed and bars. I hope this fixes that issue.
Why the hell is this a thing?

What if I can't find VoLTE in my settings? Will this still work?

How to fix network fluctuation and low internet speed [tested]

Hii Guys
Why?
"i brought a second hand mi a1 and when i inserted my sim cards in it and used it for two days, i was able to notice that indoor network is not sufficient (only one or two bars) and very much network fluctuations are there, While my Other phone with same sim cards is having 4 bars of network Then i have done some research about LTE Bands And Fixed it"
This Worked Me For AIRTEL & JIO
What i Have Done?
1. Enabled the LTE Band 8 ( which was disabled by default)
2. Disabled the LTE Band 40 & 41
LTE Band 8 is Used By Network providers for indoor network ( Like Airtel and Jio in India)
After This My Internet Speed Is Increased indoor and Outdoor also Not any Issue And Network Fluctuations are Fixed Completely :laugh:
So i Am Sharing This Step by Step Guide :
Requirements:
1. Mi A1
2. Data Cable
3. PC/Laptop With QPST And QXDM Latest Version Installed (Links Below)
Step 1. Connect Your Phone With PC in Diagnostic Mode
To Enter Diagnostic Mode:
Rooted Devices
Adb Commands
Code:
adb shell
su
setprop sys.usb.config diag,adb
Non Rooted
Dial *#*#717717#*#* ( Not Worked For me )
Step 2. Open QXDM Professional And Select Communications From Tools Menu-
(You Will be able to see your device if it is connected properly)
Select Your Device Port And Press OK
Step 3. Select NV Browser in First Dropdown Menu And LTE in Second Dropdown
Now You Will See A File " LTE_BC_CONFIG" Select it And Press READ button
A value will be displayed in Lowe Half Double Click on it and Copy it and save in a notepad
Step 4. Enter 148 Instead of That Value and Press Write Button
Step 5. Restart Your Phone And Enjoy ! :good:
( Restore Original Copied Value or Use LTE Band Calculator For Restoring Fectory Settings)
I will try to Provide links But You can Also Download QPST,QXDM and Qualcomm Drivers Manually By Searching Easily Available on Internet :silly:
Sorry Unable to Post links Because this is my first Thread

Didn't know airtel/jio uses band 8.
Anyway, in my area network seems stable enough. Also 4g+ working fine with band 40+40(Airtel).
Thanks anyway for info.
