Hi,
I DLed the MTK Eng App. I go to the LTE Switcher page and select LTE or LTE/WCDMA (or any setting actually). After I exit the page and come back it reverts to WCDMA Prefered.
I am definitely in an LTE covered area (I know because my wife's J5 is connected to LTE).
Any ideas? TIA!
you need to setting SIM 1 as mobile data defaults. it will work with no get back to lte wcdma preferred.

Hello,
I recently bought a At&t HTX one X. It has a Unlocked Bootloader and i have also unlocked it so that i can use it with other Service Providers. But i found out that the 4g is always on and when i go into the network setting, the option Data Roaming is disabled.
I am loosing a lot of money because of this.
Under the mobile Network Settings i can only see 3 options .
1. Data Roaming [This option is disabled]
2. Access Point Names
3.Network operators
Can somebody please help me with finding a solution to get 4g disabled?
Thanks in advance
Go to dialer and dial *#*#4636#*#*. Go to phone information, and pick wcdma preferred.
Sent from my One XL
ok cool.. now i see 4 options
1. Phone information
2. Battery information
3. Usage statistics
4. Wifi information
I went to phone information : - set the preferred network type as GSM only
Now i can see the 4g symbol disabled... great
But now i see the "E" symbol on.
How do i get rid of that ?
"GSM only" is this the right option i selected ?
more info
WCDMA preferred option is keeping the 4g active. i am a GSM user so tried GSM only and it worked. but the E symbol is still on.
4g = hspa (3.5g) 4g LTE = LTE
So wcdma preferred = cell and 3g
GSM/wcdma/lte = cell, 3g, LTE

This doesn't work on the AT&T version (and stock ROM), it will just go back to the default setting.
Only way to really shut it off is to flash a ROM with the LTE toggle.
thanks redpoint. can u suggest me a link where i can get step by step instructions to the rom you are referring to.
this has to get asked atleast 5 times a week since the phone came out
Hello all.
I bought a Galaxy Core from the Middle East(2 Sim cards) and tried to use it in America through Strait Talk. The phone is working fine and the only problem I have that I can not get 3G just E (EDGE) which is so slow. I put my Sim Card in a Galaxy S III to make sure that the Carrier provides 3G. As soon as I put the Sim Card in Galaxy S III, I immediately got H +. But when I put it back in my Galaxy Core I got E.
My area covers 3G
APN setting is according to Straight Talk instructions
Any idea why ?
I would highly appreciate your answer and help!!
Check network mode - maybe it is set to use only 2G. You can find it under Settings -> More settings -> Mobile Data

Mode is already set to GSM/WCDMA (Auto Mode). I can use this option and GSM Only option. I can not use WCDMA Only option. If I chose WCDMA Only, I will loose the the whole mobile service. Thanks a lot for your help and time.

Look You can't use 3G on both SIM at the same time. So choose WCDMA only on the SIM you want to use 3G and use WCDMA/GSM on other SIM and this might not be allowing you to choose "WCDMA only" so better check 2nd SIM connection type.
and yup it is common that network disconnects while change the mode of connection. It will be stable after your option is set.

In fact I am using only one Sim Card. I chose WCDMA Only and restarted the phone. I lost the service again. Thank you Bro.
I too have an issue with my Samsung Galaxy Core prime sm-g360t, my 3g is not working n I've tried LTE/Wcdma/gsm, buh it's still not working
actually ..our galaxy core now became as trash ...even i faced the same problem but there was no fix except an workaround ...the thing is lots of companies has put many features in their "new" SIMs and galaxy core is unable to process those(hardware problem) but if you use an old sim like 2-3 yrs old it will work for you ...after many many googling i had nothing in my hands but solved it by using my old sim ....just take someone's which is old and see if it helps ....

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.
