Do the S5 G900F supported bands/frequencies match your providers LTE b/f?

Then your provider uses a band/frequency which is probably not supported by the S5.
No you got it all wrong if i have in the smartphone option of LTE that are enable and not getting lte so than you right but in the device i do not have the option of LTE !

Mate there is no option to activate LTE, its your provider who has to provide you the key (i.e convert the signals you receive to the band/frequency that of a 4G).
Contact your provider and ask them to activate 4G for your connection. I had to do this procedure for mine too.
You wouldn't expect to see LTE options if your current carrier doesn't support LTE. Can you provide a link to confirm that your carrier is using LTE?
The sm-g900f handset itself supports a set of LTE bands. Possibly your carrier firmware has disabled LTE if they don't use LTE. Again we need you to tell us which carrier the phone was originally sold through and what carrier you are currently using the phone on.
Or just reflash to another 900F carrier firmware, choosing a carrier that is known to use LTE. You should do a search and find the appropriate PIT file for the new carrier and flash that concurrently with the firmware.
Alternately, do a search to find the threads that explain how to use service mode to check your LTE band preferences.

I'm having a similar problem with my S5 G-900I.
Android version: 4.4.2.

Can you tell me how did you get the firmware update?

Hi,
ROOT ONLY!
I wonder if the note 3 fix will work with S5?
backup your device before...

Be sure permissions of persist.radio.lteon are set to rw and then to “true” inside this file, after altering the file save the file and make it read-only.
Reboot your phone, now you will see and be able to pick the option “LTE/WCDMA/GSM (auto connect)” in Network Mode menu
Important: before altering ANY file on your phone be sure you have a copy of the original, unaltered file!!!
I even found: find the file with this EXACT name 'persist.radio.lteon' and delete it.
Becareful with this i perfer to chance it name & loction not delete it.. (onlt if this first meton didn't work...)

OK your problem is that you downgraded the modem and it doesn't match your software version which will make it so WiFi won't work. It looks like you are Lollipop, and I'm guessing you need unlocked modem so you can try this one- http://forum.xda-developers.com/showthread.php?t=3116542

Wow.
Are you using one SIM and a MicroSD-Card with your S7 Dual SIM (G935FD)?
Is it possible for you during a VoLTE-Call to surf in the internet or to send WhatsApp-Messages - at the same time?
Do you have in "Mobile Network Settings" also the possibilitiy to chose "VoLTE-Call" - like in my picture above?
I supposed you can do both the at same time provided you are you using a handsfree or speaker. Yes i have the option in mobile network setting.

Hi
need your guidance.
i have just got my Relicance jio Sim and put it in my S7 Edge Duos (G935FD) bought from UAE .
i am unable to use VoLTE. , there is no option for wifi calling .
could you share what CSC u have in your phone?
what can i do to get VoLTE working on my device.
Please help. i need wifi calling /hd calling
oh i forgot to mention only data is working on my device it shows 4G.
voice calls are not working directly.. only way to make voice calls from Jio sim is to install jiojoin app. i have confirmed with jio help desk there is no issue with voice and data services from their end.
so it seems to be a firmware problem.
someone, please share your firmware details and CSC details etc so i can flash the same firmware and fix the issue..
Just put Mobile in LTE MODE in cellular networks. Automatically volte signal and HD calling would be detected.

Hi
I rooted my phone and flashed king rom and csc from India. Everything working perfectly.
Sent from my SM-G935F using Tapatalk
yes jus flash csc version 1.5 and select indian csc and ur good to go. I did jus now on basic plus 2.1 rom . It should work on other roms and stock as well
i've got the same problem as evyone else here with G935F. And i dont want tot root my phone. has any1 found a way to make VoLTE work without rooting the phone?
On my S7 edge,i have flashed between all the different roms but since my HD Voice,Wi-Fi Calling, and VoLTE (All very important features for me) don't work, I reverted to my stock rom. the carrier aggregation says "CA-not configured 00" and was getting 50% worse speeds than my two year old iPad Air 2. I have ran it on many different cell towers which I know have the Carrier aggregation enabled but it sill wouldn't connect.
It may have gotten disabled somehow. CA can be enabled/disabled in the Service Menus

AT&T variant had a code on MM that you type into the dialer to being up one of the Service Menus. The code for the Verizon variant is *#27663368378# and can be accessed after root & modification to one of the carrier files for Hidden Menus.
I believe the code was *#197328640# but like I said they appear to be dead now.
Here are some screens that I took of my phone.

How do you change the files to accept the codes? If i flashed my phone to the verizon version and do this,would i lose the carrier aggregation once i flash back to att. my goal is to return the phone back to what it was prior to all the rom flashing because i plan to sell the phone on ebay so i can get the s8+
Sounds like you need to re-ODIN the firmware on your phone to trigger CA

In addition to re-ODINing the phone,I also flashed the Verizon firmware and rooted it to get the carrier aggregarion menu and when I put it back to the AT&T firmware,i still got the CA-Not Config 0 0 status in the servicemenu.On the tmobile firmware the 3x carrier aggregations work (I don't have another phone to see if AT&T CA works and I'm still waiting for my T-Mobile SIM to see if it's not the phone itself that's wrong)

Quite honestly,i think ill forego using the stock firmware,if it works on tmobile,ill happy without hd voice or volte for now
I'm not sure whether someone has done this before me, but I have successfully enabled B3+B7 CA on my ZUK Z2 through modifying RF LTE values in QXDM. For those who live in area outside China and have 4G+ interband coverage (of course your phone has to first support the bands for CA in your area), this is good news for you. If someone else needs it, I can release a guide here.
EDIT: Guide released in 3rd post.

Guide
First, make sure your phone is rooted and you have QPST and QXDM installed with all the necessary drivers. Enter your phone into diag mode through adb shell. If you don't know how to do this, a simple Google search will always help you.
Next, make sure your phone is detected in QPST & QXDM (refer to Google too if you don't know how to do it).

}
Afterwards, go to NV Browser in QXDM and select RF LTE from the category filter. Scroll down until you find a description with the content RFNV LTE B3 CA BC CONFIG.
Finally, after clicking on it, click read down in the bottom. Click multiple times on the Input Column in Fields and enter the value 524484. Click write and reboot your phone. You can also change the value of RFNV LTE B7 CA BC CONFIG if you wish to get B7+B3, B7+B7 & B7+B8 CA, still depends on support from your carrier though.
Interesting! Will try the procedure this weekend.
Thanks!
Can you give a list of all the bands which can be combined for CA using this?

Theoretically all bands which ZUK Z2 support can be combined provided your carrier supports it.
So, even TDD and FDD bands can be combined? For example FDD Band 3 + TDD Band 40.

Technically speaking yes, in QXDM there are indeed values to combine B1+B41/B39 initially entered, so you will have to figure out the number you want using a decimal to binary converter instead of the current one I gave. I did modify the values for FDD+TDD for my own setup but I can't test it since carriers in my country has yet to launch it.
thanks for the reply.
Do you know why the phone does not support carrier aggregation out of the box? the x12 lte modem supports 3x20mhz CA so why do we need to do this tweaking for it to work? I tried on a nexus 5x and CA was working without any additional tweaking. I guess it is something that the OEM decides to enable/disable?

Yes exactly. ZUK only enabled CA for bands used in China because this phone was aimed for the China market anyway, so for CA on other bands we have to unlock it ourselves.
Its possible to revert to orginal settings?

Yes. Just change it back to original values, or restore your backed up QCN file before making this change.
Is it possible to enable B20 (800MHz)?
If someone can try it, please tell me!

No. Nothing is mentioned about B20 in this thread. This thread isn't meant to enabled unsupported LTE bands.
hey man, could you share your phone's qcn file? I only need lte related nvids, you can use qrct to export them.
[little off topic]
Would someone kindly share you QCN (the stock one)?
My Zuk Z2 got the signal loss error months ago and I revert it, but now it came back and I try all the things (there is a topic about this error) and nothing I do working.
I will use my own backuped IMEI, MEID and MAC, but I need to try a non modified QCN first.
Thanks!
My QPST Configuration State Only Showing Green Bar Progress. Not Enable like yours. Any advise please
Ok, Manage to make it Enable.
Device Manager Show Qualcomm HS-USB Diagnostics 9025 (COM XX)
How to...

Am i Correct?
But...
On QXDM --> NV Browser --> No RF LTE
Try to scroll by sorting via description to find RFNV also can't find...
Please advise...

PFA for Screenshot as attachment.
Hope you can help what went wrong. Is it because of the QXDM version? I try to find the latest version, but i don't have the license.
Last, the NV ID that show on my QXDM up to 65673 only.
Update: Change QXDM Version, manage to make it 4G+
Thanks. A day and two, i realized battery drain a bit faster then normally does. It is normal, as Modem work on both B3 and B7.

All 3-4 screenshots are same in your guide... & how did you calculate B3+B7 value?
how to find the values of B5+B3 , B5+40 & B3+40 ?
Click to expand...
Click to collapse
You just need to calculate the ones you like to CA for that band, there's an app on play store for that. For example for B5, calculate B3 and B40 support together. The values are same because I set the same supported bands for them.
