Hi, first sorry for my bad english and this is my first tutorial
soo! lets start!
recently purshase a samsung s5 from verizon and i see the specs the lte bands are compatible with my network here in mexico(telcel)
soo i put the sim in the phone and he only takes 3G and H+, i go to options to change network mode and.... the problem is there no option for GSM/WCDMA/LTE, only Global, LTE/CDMA and GSM/WCDMA and for that reason dont use the band 4(1700/2100) to use 4g
i loocking for tutorials and no luck, i try the Phone Info menu(*#*#4636*#*#) and menu not pop up like other phone i have, thats why i make this tutorial to have 4g data for gsm networks and the most important you can make phone calls without change to GSM/UMTS or something like that
FIRST OF ALL I'M NOT RESPONSIBLE IF YOU BROKE YOUR PHONE FOR NO FOLLOW THE GUIDE
i have rooted with rick's rom v20 nk2 firmware i dont know if this work on other rom, soo let us know if this work in other rom or fimware BUT YOU NEED ROOT
if you have enable already the hidden menu then you can skip to step 2 if not follow step 1 to enable
1.you need to enable hidden menu: this can be done be modifyng in text editor with a program like root explorer, the file from this directory -----> /efs/carrier/HiddenMenu file
like i said with a text editor open that file and change OFF to ON and save, reboot the phone
2.when the phone fully reboot, open the phone app and dial this --->*#27663368378#
with that you enter in the servicemode
3.in service mode Select: [2]UE SETTINGS & INFO, then [1]SETTING, then select [2]SYSTEM, then [9]NEXT PAGE and then select [7]LTE BAND ON/OFF, then [2]LTE B4 ON/OFF, and finally [1]B4 Enable, need be selected like the image below:
Attachment 3092264
then restart your phone
4.now its fully reboot open the phone app and dial again ---->*#27663368378#
enter in servicemode again and select [2]UE SETTINGS & INFO, then [1]SETTING, then [1]PROTOCOL, then [2]NAS, then [1]NETWORK CONTROL, then [5]PREF MODE SET, and finally [7]GSM_WCDMA_LTE_ONLY and wait for the magic
when yor restart your phone says no service and pop up the menu dont service and tells you to change to global mode please cancel and wait for reception! if you change to global or other mode you need to do again the step 4 to put again in GSM/WCDMA/LTE ONLY
THATS ALL!:good:
NOTE: I WAS PLAYING IN THE LAST STEP BEFORE [5]PREF MODE SET IN THE [1]NETWORK CONTROL MENU, I CHOOSE [4]BAND SELECTION INSTEAD OF [5]PREF MODE SET, SOO IF THE STEPS DONT WORK LET ME KNOW TO ADD SOME EXTRA STEPS IF NEEDED
