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 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.

based on the listed 3g and lte bands, I can assume this will work fine on tmobile us? any downsides?
what for this code *#546368#*600#
and in this menu "field test" is missing..... any one help Please.
I have a zte axon 7 A2017 china version, when the phone is locked it shows the zte logo then the red led flashes and goes off.

You can use the DFU multitool from here...
https://forum.xda-developers.com/axon-7/how-to/salesmultidla2017-tool-to-unblick-dfu-t3854229
There is an English version on page 4
Or check all your driver's are up to date correct your PC or laptop show show as...
Qualcomm HS-USB QDLoader 9008 in the windows device manager.
If it shows DFU, use the tool in the above link.
Hope this helps

You are welcome.
You need a Edl package to finish the process using Miflash, there are some posted on here depending if you want Nougat or Oreo.
What did you do? i see many many bricks,because they follow steps mentioned by others (that are wrong)
For example they say,if you want to go back to stock you can connect to edl and just flash stock,but that is bullcrap
Ive never had a problem restoring via Edl, its been the packages that can cause problem.
I've always gone forwards with my ROMs never backwards.
Some Edls fail the hello packet (eg: the turdevs package I was using failed)
The Edl packages by Djkuz have all worked.

You can't flash hardware...
If you flash a different modem (which you totally can without even qcn) you'll just lose signal. Flashing a QCN backup would probably wipe your IMEI

I have already tried different QCN from other brands, but none of them works, I need to get the qcn zte axon 7 a2017g or a2017u to try.
The imei I have it annotated to restore at any time.

keep trying if you want, but it's surely that you're lacking the necessary bands. did you even check before?
Also, "different QCN from other brands"? What other brands???
There are a number of reasons why you can't get 4g, SIM card is one, band support is another.
I had to change a SIM because it was only running 3g not 4g, I wouldn't keep trying other backups in case you break your phone completely.

I'm inside the 4g coverage, the chip is 4g, I've tried it on another smartphone and if it captures 4g, the problem is the band
My axon is Chinese, it only has FDD LTE band 1,3,7
through DFS tool I have activated band 8 because it is what I need but the phone does not recognize it as LTE but as band 8 GSM and there is no signal, only 3G capture
It seems that it is impossible to activate the other bands in this zte axon 7 A2017

Where are you living? Your phone just may not have the other bands in it. Nothing that can be fixed with a modem or qcn flash.

I tried using flash with qcn files with unlocked bands, but they were from xiaomi phones, one more, zte axon 7 mini, but it did not work for me.
How could I edit the QCN of my zte axon 7 to activate the bands?
There will be some way to edit a modem (NON-HLOS.bin). It would be excellent. Maybe it works for me.

Sorry, but you don't understand. The bands are hardware based, not software. The modem files will help the bands recognize the towers, but nothing will add extra hardware. I'm assuming you don't have Claro as your carrier? If you do have Claro I don't know why it doesn't work, but if you don't have Claro you should get an a2017u. For example:
A2017: https://www.frequencycheck.com/compatibility/Eaj5CJl/zte-axon-7-a2017-dual-sim-td-lte-64gb/peru

If in my case the blockade can be by hardware there is nothing I can do.
I understand the subject. I already tested with chips from several operators in my country, none of them recognizes 4g on my phone, even clear.
That's why I go to the experts of xda.
Bands LTE Perú :
Movistar : band 4 (1700/2100 MHz) Band 28 (700 MHz)
Claro : band 2 (1900 MHz) Band 28 (700 MHz)
Entel : band 4 (1700/2100 MHz) band 28 (700 MHz)
Bitel : band 8 (900 MHz) band 2 (1900 MHz)

Also, as is the case with some carriers in the United States, you may have the necessary bands but it may not be permitted on their network. They can choose which phones to allow and which to not allow.
Hi there. I bought an 'unlocked' AT&T H910 LGV20 from ebay.
I thought would work in the UK as the phone hardware has compatible 4g bands that my provider (EE) uses.
The stock at&t firmware only allowed me to use 2g/Edge.
So I have flashed several other roms / kdz files using LGUP
( h910 Puerto Rico, H915 Canada, US996 unlocked US - variety of android 7 and android 8)
Some roms (particularly Android 7.0 Canada and Puerto Rico) work with 2g and 3g but there isn't even a 4G option in the base menus.
Some roms have global or allow you to select LTE/3Gpp but they don't allow me to get a 4g signal.
One even said 4g at the top but when I checked the connection in phone settings - about - it showed 3g (and this was consistent with the download speed too)
II only got videotron Canada to work. Bell and Rogers should have an overlapping 4g band but I got the CUST error on those roms.
I have tried going through service menu but all that can do is sometimes force a 3g signal from 2g
So what should I do?
1. I s there a rom with overlapping 4g bands that would work? Can I flash a HK rom onto H910?
2. Can I root the phone to unlock 4g bands?
Would this survive unrooting to allow me to access microsoft intune (for work email), banking and sports apps (which sometimes don't like root?)?
3. Would a custom rom work? Which do you recommend to keep as many features as possible eg remote control, camera, DAC?
Do they also work with microsoft intune, banking apps, sports apps etc?
I have followed a few of the posts out there but given the ebay seller I wonder if a few more people in Europe might have been tempted!
Thanks!
Hi
You need Band 20 (800) to use with EE UK and according to GSM Arena list of specs for the H910 that version of the V20 does not have it and I do not know if it can be added.

Thank you!
I was led to believe the H910 (same as H915 in Canada) supported all of EE's 4g bands.
But for sure, the carriers seem to have locked some out. But not having any luck with other roms either...
I cannot post the url but
frequencycheck . com
carrier-compatibility/wwW4hXP/lg-h910-v20-lte-a-h915/ee-everything-everywhere-united-kingdom
Compatibility - 3 out of 3 bands supported
100%
Interface Name Supported by device?
LTE B3 (1800 +) Yes
LTE B7 (2600) Yes
LTE B20 (800 DD) Yes
As I said in previous post the H910 does not support Band 20 (800) check GSM Arena site select LG V20 and then H910 and select LTE bands and you will see that Band 20 is missing. The H915 is not listed.

I have a similar issue, having bought an "unlocked" H910 and having only 2G. Is this the file name of the H915 kdz file you flashed to enable 3G: "H91510e_00_VTR_CA_OP_1205.kdz"?
Thanks.
