No LTE on D802 KK - G2 Q&A, Help & Troubleshooting

I have bought second hand G2 and it had already KK installed. Baseband M8974A, kernel 3.4.0
build number KOT49I.D80220a, software version D80220a-HKG-XX. I have rooted it only and everything works fine except I don't have LTE option in network mode. Is there anything I can do enable it? Also, when I use 2G only the signal comes and goes sometimes (I have pretty strong 2G signal so that shouldn't be happening). Please help

I have done this:
If anyone of you has root, but LTE/4G is not sticking after root, you can try the following:
-In build.prop change ro.telephony.default_network=9 from 9 to 11!
-Now you got LTE settings in "settings / tethering & networks / mobile networks / network mode" menu.
-Choose the option you want and includes LTE and it sticks after a reboot!
Now I have LTE in option. But somehow managed to silent some system sounds... For example keyboard clicks... Dunno how

{Q} How can I switch/select cell bands (LTE/3G/Etc) on the S4 /ATT/i337?

Hi!
1. I have an i337 rooted and rom'd ( Shostock2.1!!) & was looking for the option to control bands (LTE-4G/3G / 3G Only/ etc.)
2. It appears that (at least) the S4 international version has a "network selection mode" option in
. . . . settings / connections / more networks / Network Mode <== this menu option is in international version but not i337!
3. My i377 does not seem to have that option in settings, or any other likely location
4. So, I am wondering if it has been removed by AT&T (likely), or did I miss something?
5. If the AT&T i337 does not have network mode menu, does that mean there is no direct user control over band selection?
Thank you in advance !
Rooted, Unlocked ATT S4 i337
Same problem here ! I Can't switch from 2g [E] to 3G[HSDP/+]
Hope someone can help.:good:

[Q] LTE lost after KK update

I have a G2 d802 originally with the Taiwan rom, Im using it in southeastern Europe and had LTE just fine on the original JB 4.2.2. rom, the selection option was not present in the network mode settings, but after selecting it in the 3845#*802# menu it was working just fine, after I received the OTA update to KK 4.4.2 I couldn't get it to work again, when I selected LTE only option in the secret menu it wouldn't register to the network, and all the bands were not selected and I couldn't select them in any way.
So I tried to flash the KK EUR ([ROM][D802]80220B EUR Open KITKAT Flashable ZIP With Custom Recovery Working! rom hoping it would solve this issue, now I have the option to select the LTE/3g/GSM in network settings, but still can't get 4G, and when I try to enter the 3845#*802# menu and select LTE only option it gives me “not supported”.
I also tried to flash a few different modem firmwares but still the same situation.
Any idea what the issue is and a way to solve it?

[Q] How do you switch on LTE 4G for D802 in uk

Hi,
I imported the international D802 version from eBay HK and updated to the KitKat UK firmware using the support tool.
I'm on Three and the 4G works when I have to manually switch on LTE using the service menu key hack "*#*#4636#*#*".
However this is not permanent and it does not show up as one of the network modes in the system menu.
Does anyone know how to get the phone to always recognise that it can choose 4G normally under Mobile Networks > Network mode

N910-S Network Mode

I recently bought an unlocked N910S but I seem to be having some problems with LTE (I live in the US) and can't seem to access the network mode menu in 'more networks' (the option is grayed out).
Some things I've tried:
Added the access point for my provider (Cricket/AT&T)
Booting in safe mode (no changes).
Flashing other regions' stock roms (N910T, N910V, N910T); Odin gets stuck at NAND wrtie start and only N910S stock rom seems to work.
Accessing Network Mode settings through the hidden menu (can get LTE if LTE17 or LTE All is selected but can't make or receive any calls).
Any help would be appreciated.
Thank you.

Using ATT LTE now. Stock rooted to remove a bunch of Korean apps. Use band 5 preferred in the hidden Menu. Band 17 also LTE but couldn't make phone calls. ATT LTE band 2, 4, 5, 17
