[Q] No 4G toggle button?

Hi guys, today I flashed my phone for the first time to generic global .93 ftf and it all seems to be working fine. My only problem is, before I flashed (and also on my old xperia z), there used to be an option to enable 4G with a toggle button from quick settings. However, on this ftf I do not have this option at all so I have no idea how I would turn 4G on.
Would I have to flash the UK ftf for it to appear back? My only concern is the UK .93 says .98 and I wanted to root it which is only available on .93..
Any help is appreciated, thanks!
Edit: I have looked around everywhere and under mobile network settings>network mode, my option for LTE has disappeared? I am only left with 3 choices, the 1 it is on atm is WCDMA (preferred)/GSM. Weird because before I flashed, the LTE option was available..?

Did you flash the right firmware for your phone since several D66xx variants are available.
Can you select LTE in the service menu (dial *#*#service#*#*) under service settings - network mode?

Yes I flashed the correct one (I checked with many users first too) it was D6033 & I flashed the global generic one onto it. I can see LTE under service menu but everytime I click it, it goes back to the wcdma_pref one
Edit: Although now when I go onto settings, then under mobile networks settings, network mode has stayed under LTE (PREF)/WCDMA/GSM - but there is no actual option to choose that when I click on it?

I'm from Denmark btw, so i just downloaded flashtool and flashing the "D6603_23.0.A.2.93_Customized_20NCB", if i get my 4G i let you know.

D6603_23.0.A.2.93_Customized_20NCB.ftf is working fine! i got the 4G button now and i can choose LTE in mobile networks. You can download it from here: http://forum.xda-developers.com/z3/general/ftf-stock-firmwares-xperia-z3-models-t2886061

Do you mean in NC quick settings? Because for me on .77 it isn't showing as default but if you press "edit" There's an option to add it.

I fixed the problem - it was simply the ftf for some reason not giving me the option of 4G, I flashed a different one (Generic UK) & it worked perfectly again!

Hiya,
I flashed a generic 93 ftf so I could root my Z3, then I flashed a pre rooted zip that I made for Lollipop straight after.
LTE working fine again now, I'm back on the UK firmware.

Galaxy S6 (SM - G920FD) Mobile Data Issue/Problem

Dear Senior Members and developers/experts,
I need your urgent help regarding the issue of mobile data that I am facing in recent days. Please see the pic as attached. My device info is also attached for your information. I am using Galaxy S6 DuOS and facing the mobile data problem. When I select GSM Only (2G) (Attachment 2), my mobile data is all right. Sim 2 selected GSM all time (Attachment 3) with no problem. I am using mobile data from Sim 1. When I select WCDMA/GSM (3G/2G), my mobile data HSUPA showing connected but no internet connection and emergency calls only appears (Attachment 4). And lastly UMTS and mobile network state disconnected (Attachment 5). Please note that my IMEI 2 is not valid according to IMIE.info and mobile info application. I have the mobile data available when I purchased but after OTA update, this problem occurs. THen I flash sam firmware but no improvement. Any solution regarding this will be appreciable. Thanks.

Try going to recovery mode and wipe cache. You can also do a full reset if it does not work.

Roydok, I did that when I flash new firmware from Sammobile. com but no improvement From HSUPA it automatically goes to UMTS and no internet connection and no call, sms etc. See the attachment 5 screenshot.

SIM card problem. Bring your S6 back to your network provider for check-up.

Not actually a SIM card problem. I had already change SIM card 2 times. When I select WCDMA/GSM the problem activated in SIM1 or SIM2 whenever I selct anyone for mobile data.

Note 5 SM-920P bought in China

I bought a Note 5 which worked fine with China Unicom, the phone was 5.1.1 so I decided to manually update the phone to mm. After the update the phone can make calls, but it can't pick up data signal. I've tried everything from flashing the modem back to 5.1.1 (which was the one that worked, originally) but no dice. I was wondering if anyone had a solution to this. The phone isn't rooted and its constantly trying to activate its voice and data, even though the voice all ready works.

Enter the APN settings manually for your network. The same happened to me on my Unlocked N920P. I entered the APN (Airtel India) and deleted all the others. On upgrading, it will automatically pick up the Sprint APNs. So add a new APN and enter your setting for your network manually.

It happened to me too. The first step was the APN. changed the APN manually on mine but still it seemed no data connection was active. On step two I discovered that even the data seems not active, in reality there was a data connection and everything was working, but the icon was not showing due to something missing in the Sprint's SystemUI data connection icons.
So, try to put your apn manually and try and check if there is a data connection, i.e. using the browser to navigate.

Open the notification panel - touch the "down arrow" symbol on the upper right corner to show all the icons and look there must be the data connection icon you're looking for.
As for the update: Updated myself to MM and everything works fine with the exception of 4G. This is not something caused by the update but because the LTE-4G bands the phone works are not compatible. Check yourself @ willmyphonework.net

Flash pure GSM kind of roms.
First go to official MM by ODIN, root it,
Via TWRP, flash Lamlazy ROM or aurora rom which is compatible rom without sprint stuff.
Try this rom http://bbs.gfan.com/android-8394771-1-1.html
Download link pan.baidu.com/s/1c2JZgje PW kr10
I didn't try yet. but it says N920p supported. If u are on sprint, am not sure how it works.. but GSM should work well.
That V7 of Lamlazy can be found here -- thread http://forum.xda-developers.com/show...&postcount=153

Is there an IMEI number showing in settings?

Yes It Shows IMEI number and 2G and 3G networks can able to connect ,but the problem is only with 4G ..so 4G networks are not detected if I do manual search of network then also same problem remains..Device only detect 2G and 3G network
