Hi guys,
I've researched a little bit with no positive results, and have a question: is there any what to add/enable/unlock bands for D800 and D801 versions?
My main device is the D800 (tried with CloudyG3, CloudyStock and now a D802 rom with D800 kernel) and recently bought a LTE plan in my country (carrier uses 3G 2100MHz and LTE 3), so my first question is: does it exists any way to enable LTE band 3 for AT&T D800? I've tried with 3845#*800 > LTE-Only > Modem Settings > LTE Band Selection and tapping Band 3, but there is no SUCCESS popup. Confirmed device is LTE/GSM/WCDMA enabled with *#*#4636#*#*
Now, tried with D801 (running stock 4.4.2 TMO D80120g) and I've no data at all, not even 2G data. I've wiped the device, replaced SIM, deleted/created APN, tried enabling same band with hidden menu and received SUCCESS popup but no results as well. Also tried 3845#*801 > WCDMA-Only > Modem Settings > Network Mode > tapping WCDMA 2100 or Automatic.
Summarising, can I add/enable LTE band 3 on D800 and WCDMA/UMTS 2100MHz to D801?

hi my problem is that i am trying to get LTE in my att LG G2 that i actually flash with the CleanRom V1.3, but when i go to setting mobile network and try to chose GSM/WCDMA/LTE auto it does not select that option so i cannot have LTE in my phone and i know i can have LTE because i used to have a galaxy S4 and it was always LTE, is there anything i can do to be able to obtain the LTE signal? i tried changing APN and it does not work.. thanks
Hi, I just installed CloudyFlex 1.4 with my LG G2 D801 var. Wind/Videotron. The only version that was working for me was the D803 canadian version. Once I've installed it, I didn't have LTE/4G anymore. I've tried several tutorials such as

Type in dialer:
3845#*802#,then the secret menu will come up...Then:
1. Go to LTE-Only
2. Modem Settings
3. RAT Selection
4. Select GSM / WCDMA / LTE auto

but I still have 3G. Is there a way to get back my 4G?
look for a 4.2.2 modem for your device and carrier. that should help.
what do you mean by modem?
I am on Indian D802 32 GB with Official Indian 4.4.2 KitKat ROM. I am travelling to a country where there are Band 40 and BAND 3 LTE networks. But in network config settings where we choose network mode, LG has hidden the option to select LTE.
So which Euro/SE Asian KDZ has that LTE option enabled?
Thanks a lot.

*#*#4636#*#* This will take you to that menu. Is that what your asking? An easier way is to use an app called 4g toggle, it takes you straight into that menu.
I own a i9505 International LTE model. My carrier has soon went for TDD LTE in Romania which is a first here. As everybody knows this far the i9505 only supports FDD LTE.
There seems to be two S4 models i9507 and I9507V that both support TDD LTE bands and are available in HK and Australia.
Tried flashing the LTE modem from those models but my bootloader refuses the file and i get an error in ODIN.
I used QXDM and modified the phone. DFS CDMA tool uppon scan now shows my phone accepts the stock LTE bands + Band38 but when
the phone attempts to connect to the Band38 it goes with no signal no network then falls back into 3G.
I believe i enabled the permision to connect to Band38 but because the modem has no instructions of it , it still can't communicate on Band38
There have been reports of i9507+-V users that flashed i9505 roms and theyre modem got overwriten resulting in no more DATA connection for them. It's clear FDD modem on a TDD network will not work.
Is there any chance of forcing the LTE modem from i9507V onto the i9505 phone ? Would Heimdall overpass the bootloader's check ?
The i9505 latest bootloader and modem is OH2 , on I9507V there is OH3
Also what is the worst case scenario ? I would imagine FDD network loss and/or wifi. Is that impossible to recover from or flashing the correct modem over would fix it ?
Anyone encoutered flashing the wrong modem file and recovered from it ?
I don't care if i loose FDD networks since my carrier only has TDD on 4G.
Also. Would it be possible to combine the i9505 5.0.1 sources against i9507V 5.0.1 sources and come up with a combined/hybrid modem ?
You are from Romania?
Yes.
I read that it can be activated with QXDM on lg g2 and sam. s5. Did you tried it?
I used QXDM and added band38 , when LTE is enabled in network type it works 5%. It tries to connect to the 4g signal then drops dead with no network no signal and goes back to 3g.
QXDM only adds permision to connect to certain bands , the i9505 modem does not have the instructions on how to communicate with a TDD network (band38 is TDD not FDD)
Nobody owning a G2 , G3 or S5 managed to add a functional TDD band. You can add more FDD bands thats for sure but not TDD without a proper modem.
That's why i'm curious about binding the i9507V modem with I9505 somehow so it gives it the instructions on how you can communicate on TDD networks.
That is sad. Because to the and of this year rcs will introduce lte in my city as well.
Hi.
I have a Galaxy Note 3 base model n9005XXUGPQB1 but i want support for LTE 4 AWS band (because the 4g company in my country works in that band).
I read about a modem firmware in Odin. But i don't have a lot of information (And i used the search but nothing it's clear).
Can you help me, please? I'm using right now Resurrection Remix according to this topic: https://forum.xda-developers.com/ga...p-nougat-holy-grail-hlte-rock-stable-t3630301
Thank you

Yeah, I know that topics. But they don't have any explanation about my issue. What modem firmware i need to install? Why?
Thank you for your links but i need a little more help.
Install the modem for your network.
Don't work. Other ideas?
Thanks

Why not just activate the band 4 LTE in the service mode on your Note 3 SM N9005 ?
B4 (1700/2100 AWS 1), this frequency is used for North America as well as from South America.
It may be necessary to modify the feature/other.xml file in the CSC once the activation is done.
Because that mode don't work in Resurrection Remix. I'm trying to return to the stock firmware.
Okey. I activated the band with the *#0011#, back, input "Q0" in serviceMode. (Main Menu -> LTE -> LTE RF -> VZW LTE B4 on/off -> B4 Enable.
But my 4g is still don't working. If i search for "LTE favorite band" i saw a lot of bands except for Band 4.
Where is the problem? Thank you
