I want to ask if it is possible or anybody can modify any modem to have all lte band activated and after that to flash them on phone?
PS i ask that because i have this phone model and i need to activate lte on band 38 2600.
i need the same thing, we are in Romania with Digi Carrier, my phone works only on h+

I'm trying to get through the steps. You need to start with a radio that has some level of LTE support.

Hi, guys.
I have ls980 on stock ZVA, rooted and GSM unlocked. 3g works fine, but there is no LTE. I live in Russia, and our LTE bands are 7,20,38.
So, is there any way to enable other LTE bands than Sprint's 25,26,41? To flash proper radio or baseband may be?
Thanks!
the same question. Any solve?
No I don't believe you can just flash different modem and enable bands because the phone has different models... Chances are it is a difference in hw and flashing an incompatible modem may cause a brick
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 Guys,
I have read lot of comments & QA's, still i have no clarity.Some one please clarify me.
If i buy S7edge Verizon (Sd820) can i use it in india.Verizon bands are 2'4&13. However i heard that verizon lte phomes are unlocked. Can i use in india lte network(Jio or Airtwl LTE network.
However locking is software thing(firmware), can i install international firmware (935U , not sure) to unlock all lte bands, to use any simin world....

you have to add lte bands by qxdm method or you shouldn't buy the varizon device.

Decided to pull the trigger and do this following a guide on Youtube. I used firmware G935VVRU2APD2 and followed this how-to https://youtu.be/WVzXvMa5FQ4 and everything worked out perfect.
Hi, I have a korean LG G6 G600L model. I am based in Germany and use the T-Mobile (DTAG) network. LTE Band 3 works but I would like to check the LTE band list on the device itself. Does somebody know the network test menu code for this specific device/network?
Additionally is it theoretically possible to exchange the modem driver to enable additional LTE bands (Band 20 in my case) ? Is it only possible with root?
Happy to test stuff on this device as I would really like to keep it and improve the LTE reception. I love the DAC btw.
Thanks.

Hello
Just a question
Do you think if i flash a different firmware (H870) in my mobile (G600L) i can receipt UMTS 900 ?
It will not help u to add WCDMA b8 900 to supported bands, because:
1. Korean submodels probably have no hardware antenna support for this band, which is totally unusable in Korea;
2. U will not be able to flash another submodel's stock to Korean models without root and some rom cooking preparations, flasher just restricts u to flash another submodel's stock;
3. In case u modify another submodel's stock enough to sucesfully flash it to Korean model, but without Korean kernel, modem and specific patches - it will probably softbrick ur device.

Thank you for your reply.
I will change my modele by another
So I can confirm that G600L is not only showing the bands but also work with them. Band20 and 3 successfully tested here in Germany. Now if it would be possible to configure VoLTE with T-Mobile or cross-flash the german firmware but still keep the DAC would be perfect for me...
Looks like the Korean version has the most international 4G LTE Bands. The rest of the models in Asia barely have any 4G LTE Bands. Not sure what is used with this. Is the Korean version a dual sim version as well? Anyone have a picture of the box of the Korean version? There is usually a sticker on there that shows which 4G LTE bands are supported on box
---------- Post added at 02:58 PM ---------- Previous post was at 02:54 PM ----------
One more question.. Anyone here that has the Korean version able to tell us if it comes pre-installed with facebook? Do not want a smartphone with Facebook preinstalled that can only be disabled and not uninstalled.

how did you bring up that menu with all the bands? I have the lg h870ds model with hifi dac and 64 gig, but I can't locate the LTE bands to turn them on
Try the same but with 870 instead of 600.

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
