[LG V10 General] Brobro1:
It's my guess that we all thought you meant that LTE Band 7 (2600 MHz) is overriding your LTE Band 20 (800 MHz), but that has little to do with CDMA.

From your quoted comment, it seems that you meant UMTS-FDD (and not LTE) Band 7 (2600 MHz) is overriding your LTE Band 20 (800 MHz).

That's a night and day difference, my friend: First situation (LTE Band 7 [2600 MHz] is

BETTER

than LTE Band 20 [800 MHz]) is desirable in most cases (except for battery life in some instances), second situation (UMTS-FDD Band 7 [2600 MHz] is

WORSE

than LTE Band 20 [800 MHz]) is undesirable in almost all cases.

Remember that both LTE Band 7 (2600 MHz) and LTE Band 20 (800 MHz) are LTE (4G) bands, so forcing LTE only on your phone will

NOT

affect the functionality of either of them (as described here: http://xdaforums.com/showpost.php?p=65362251&postcount=578 )!

It all depends on what areas of the phone the stock KDZ overwrites, you see: It can easily overwrite the antennae parameters: We'll never know until someone tests it out!
[LG V10 General] Ruxst:
Morning guys!!! Wao this thread got activated! Nice [MENTION=3250956]melorib[/MENTION] hopefully the bands will stay active after a clean flash!

[MENTION=2363601]a_petrov303[/MENTION] just like the guys said... If you do root you will never stop doing it.. Besides the benefis are Real! Using Xposed to modify your phone looks is one of them... Btw guys it works like a charm!

Another one (and most important to a lot of us) activate lte bands to make our device fully compatible on our countries!

Hope you try it out! But before doing anything... Read a lot !!
[LG V10 General] melorib:
This time I didnt mix things up ;)

It is Band 7 that my phone picks in my house when I force LTE only, if I leave it on auto then it changes to UMTS...

For those who installed Closed and got an issue with `Second screen not working` like in my case here is the link to fix it. http://xdaforums.com/lg-v10/general/xposed-fixes-screen-t3246515

Thanks to tattedup.
[LG V10 General] Brobro1:
Which Band 7 you meant in this post? LTE or UMTS-FDD?

I thought your questions were about LTE Band 20 (800 MHz) not being picked up!

What about LTE Band 20 (800 MHz)? When does that work?
[LG V10 General] melorib:
Band 7 LTE, UMTS doesnt even mention which band...

Band 20 works for a while after I force it, but eventualy changes to band 7 LTE if I am on LTE only, or to UMTS if I am in auto...
[LG V10 General] Brobro1:
OK, makes sense:

Your place of residence has both LTE Band 20 (800 MHz) and LTE Band 7 (2600 MHz), but neither of their signal seems uninterrupted (for some reason).

This means that whenever your LTE signal drops (even for a split second) and your phone allows it by having your SIM set to 2G/UMTS/LTE, your phone automatically downgrades your connection to UMTS to keep at least the last generation connection stable.

There are generally two fixes to this: 1. Have your carrier build more transceivers in your area. 2. Set your SIM to LTE only.

This also means that if your SIM is set to LTE only, it will prefer LTE Band 7 (2600 MHz) over LTE Band 20 (800 MHz), because it's better/faster.

The two fixes to this that come to mind are: 1. Go to that larder I talked about 2. Use CDMAtool to lock LTE Band 7 (2600 MHz).

Good luck!
[LG V10 General] melorib:
I only prefer to be able to call people without having to stand near the window, and LTE 20 allows me that, at least it did yesterday, now I cannot call :eek:
[LG V10 General] Brobro1:
So with LTE 7 you can call only near the window, but UMTS is too slow for you, correct?
[LG V10 General] melorib:
UMTS I can only call near the window... Now I have a problem LTE band 20 is not making nor receiving calls, maybe I need to enable it again after the TOT :confused:

Going to do it...
[LG V10 General] Brobro1:
Hmmm... report back with your findings, please! This seems interesting!
[LG V10 General] melorib:
Same thing, very strange, data works on LTE only, calls only work on AUTO, regardless of the connection being LTE or UMTS :confused:
[LG V10 General] Brobro1:
What exactly did you uninstall when you got the Security Error the first time?

Did you get the error straight after uninstalling or after reboot?
[LG V10 General] melorib:
Useless things like initial setup, I always uninstalled that on Samsung, error after reboot...
[LG V10 General] rcyh:
Correct me if I am wrong. Unless your carrier supports VoLTE, when a call comes in, the phone will downgrade to non-LTE (UTMS? 3G?) for voice call. Carriers in most countries are still having LTE to support data only. So [MENTION=3250956]melorib[/MENTION]'s case is not uncommon.
[LG V10 General] melorib:
You might have hit the nail on the head, there is a setting VoLTE in the hidden menu, I press several times and nothing happens, maybe I disconnected it :confused:

[LG V10 General] melorib:
I used FDS again to enable ALL LTE bands.

Comparing with standard I now have 15 instead of 9, 6 more, 9 new and 3 missing:

+ 2, 4, 5, 12, 13, 17, 20, 25 and 29

- 38, 39 and 41

I ticked every LTE band on FDS #6828 and #6829 :confused:
[LG V10 General] ivangundampc:
In fact, i found that some model can be flashed in some modified custom recovery with locked bootloader, such as Xperia Z.

Don't know whether we can do something like this on LG V10.
[LG V10 General] petalex99:
That's right. On my old Xperia Z1 I had Philz Touch CWM & TWRP recovery for locked bootloader. But for our LG V10...... we haven't yet a developer!

Wow! Nice work, man. I'll check in with the devs on that one.

Still not keen on reflashing back to stock to check whether the bands work both in the Field Test and real world deployment? That info would be golden :P
[LG V10 General] a_petrov303:
also, please do summarize after you do the test what the maximum number of bands one can "squeeze" out of the V10 and if possible the full procedure for novices like myself :o

many thanks!
[LG V10 General] melorib:
I have 15 LTE bands on mine...

Downtown on AUTO the phone used LTE band 20, made calls, ok :good:

Then I went on hidden menu and changed to "LTE only", no calls again, only data, looks like in this mode VoLTE doesnt work :confused:

Back to AUTO, still band 20, everything working again :cool:

I have already tried to use flashfly to flash the twrp image of H901 to the recovery partition.

However, when i tried to boot to recovery, the bootloader has showed somethings like "secure boot - error, modified".

It seems that without unlocking the bootloader, we cannot just simply flash a custom recovery into it.

May be we need a modified twrp which can cheat the bootloader and let us boot in.
[LG V10 General] EnIXmA:
Is there a way to change the 4g icon to LTE? Is there a way to hide the empty signal bars for the second sim when it's not being used?

Thnx
[LG V10 General] coremark:
I remember I did this on my previous phone where it showed 4G. I was able to change it to show LTE instead of 4G using Gravity Box under "Signal Cluster settings". Unfortunately, I haven't installed xposed yet on this phone. Not quite sure about the 2nd set of signal bars though.

[LG V10 General] a_petrov303:
thank you!

So I double click on LG (COM3), then choose diagnostic tab - nothing there.

I choose band tab - I see that ALL the bands are ticked and greyed out (both in CDMA/GSM/HSDPA and LTE tabs)

is this normal?

sorry if I ask too much, but this is potentially an easy task if I receive more instructions on this step which has so many options, tabs, ports etc... :confused:
[LG V10 General] melorib:
Not diagnostics tab, when you open DFS there is a screen with the log behind the main screen, there you check the success, or not, of what you do, and if the usb connection is "diagnostic mode" or not connected, or whatever...

[LG V10 General] a_petrov303:
can we enable more bands for wifi too with DFS software?

I see there 2400 and 5000 - I assume these are bands, right? anyone who understand this software better than me tried it?

thank you all for the help! anyone tried factory restore? does it keep the root and unlocked bands?
[LG V10 General] Brobro1:
What LTE bands did you want to unlock? What carrier/country combination are you using? Do the bands work in real world deployment?
[LG V10 General] magicbb:
I lose VOLTE after root. Is it normal?
[LG V10 General] Brobro1:
Have you tried unlocking any LTE/3G bands as per this guide: http://xdaforums.com/showpost.php?p=65254465&postcount=368 ?

EDIT: The above is just a question relevant to diagnosing your problem, not a proposal for its solution.
[LG V10 General] a_petrov303:
I am on Orange Moldova. 4G was working for me before root. From what I gathered in this topic, it was LTE band 7. This works now as well after root - I checked in the city (full bars, good coverage).

I wanted to unlock as much potential of this great phone, as realistically possible. So I checked unlock boxes for all 15 LTE bands mentioned earlier in on the last few pages. This would come in handy when traveling to another location where I cannot check in advance which bands are working or not.

So far so good, I just want now to factory restore the phone IF the root will be maintained along with the unlocked bands.
[LG V10 General] Brobro1:
You will definitely lose root if you reflash back to stock rom.

No one knows whether the unlocked bands will persist through a reflash back to stock rom, and no one is willing to take the plunge and try it out yet, either!

We're waiting for the hero to come along.

Shame you can't TRULY test it out yourself (since you only have access to LTE bands 3 and 7 which are both unlocked in stock rom), but you can certainly be of tangible help.

When you go to Field Test menu, does it show SUCCESS when you test LTE Band 20 (800 MHz)?

If yes, then you can reflash back to stock and do the Field Test again in the stock rom and see what you get.

Also, what model do you have: H961N or H962?

Thanks!
[LG V10 General] a_petrov303:
I have H961N

I am no very comfortable with field menu test, as it did not seem to be documented well, at least I did not see a step-by-step guide on how to do this.

How do I find out which bands are available in my country? Is there a knowledge base or something?
[LG V10 General] Brobro1:
Sources like this help: gsacom.com/wp-content/uploads/2015/10/151013-Evolution_to_LTE_report.pdf

On your phone press 277634#*# (or, if that does nothing, press *#546368#*961# instead), select Field Test, select Modem Settings, select LTE Band Selection, select Band 20, wait a 10 seconds and report if it says SUCCESS, FAIL, or whether you get no response after 10 seconds at all. Compared to rooting and unlocking LTE bands, this risk of this procedure damaging your phone is nonexistent.
[LG V10 General] magicbb:
No, i live in Hong Kong. There is no need for me to unlock the band.
[LG V10 General] a_petrov303:
thank you!

I get FAIL on all bands listed there (from 1 to 40 with some exceptions).

But I have used band 7 just 10 minutes ago while walking in the park. Nevertheless, the Fieldtest menu shows it as FAIL :confused:

BTW, according to the document you shared on bands allocation worldwide, in Moldova one would need theoretically bands 1,7,8,20, 42, 43 - is this bouquet of bands achievable on a H961N?

Update: while moving through the building (and disconnected from my Wi-Fi network), LTE Discovery app indicated that I have connected to bands 3 and 7

[LG V10 General] a_petrov303:
Yes, I have done (to best of my possibilities) everything as per instructions. Only thing I did extra to instructions, was to read/write in the CDMA tab once for Band Preferred option and once for RF BC Config (please see the screens attached)

Yes, absolutely all bands (I have tried ALL of them) returned FAIL.

However, band 3 and 7 works in real life (according to LTE Discovery app)
[LG V10 General] Brobro1:
What do you mean "extra"?

That's step 10 of the guide!

Unless I misunderstood what you're saying!
[LG V10 General] melorib:
Mistery solved, Vodafone Portugal doesnt do VoLTE, thats why I cannot call on LTE only :(
[LG V10 General] a_petrov303:
well, the guide said to read then write once for LTE BC CONFIG DIV LTE#6828 variant, then again for LTE BC CONFIG DIV LTE#6829 (read and write) - correct?

then I selected tab for CDMA bands, and again there are 2 options:

(O) Band Preferred

(O) RF BC Config

I have done read/write once for Band Preffered and then once for RF BC config.
[LG V10 General] Brobro1:
You didn't read it properly, then!

The updated guide says:

The former guide you most likely followed says:

Anyway, you may have a problem: You might have damaged the antenna rom region!

What

exactly

did you change in the CDMAtool (LTE/CDMA/GSM/WCDMA/WLAN)?
[LG V10 General] a_petrov303:
I just clicked read and write - once with the band preferred option selected and once read and write with the RF BC Config option selected

---------- Post added at 03:35 PM ---------- Previous post was at 03:34 PM ----------

I did not make any selections in the cdma section, I only was ticking bands in LTE section

---------- Post added at 03:40 PM ---------- Previous post was at 03:35 PM ----------

I think we should make the updated guide sticky so that everyone finds it and not the older one. I did indeed follow the older version of the guide.

In LTE section I have checked additionally to those which were selected by default: + 2, 4, 5, 12, 13, 17, 20, 25 and 29 read/write once, then read write with default settings second time

in the CDMA/GSM/WCDMA/WLAN I did not change anything - just read/write 2 times
[LG V10 General] Brobro1:
The older guide does not exist anymore, I updated it with the latest one.

You should have read/write a total of four times, once for LTE with unlocking the desired LTE bands (LTE tab), once for LTE BC Config DIV LTE #6829 with unlocking the desired LTE bands (LTE tab), once for Band Preferred with not unlocking any additional bands (CDMA/GSM/HSDPA tab), and once for RF BC Config with not unlocking any additional bands (CDMA/GSM/HSDPA)!

This was a mistake!

I suggest you follow the guide from the beginning (and enable just all of the LTE bands in the LTE tab without adding any additional bands in the CDMA/GSM/HSDPA tab), because it seems that you haven't successfully unlocked any additional LTE bands at all yet!
[LG V10 General] a_petrov303:
I will do it again now from beginning, yes.
[LG V10 General] a_petrov303:
I have done it again. I documented every step and logs are there to prove. How does it seem? Correct?

[LG V10 General] Brobro1:
Reflash to stock to see if you get it back.

Do you have "Enable OEM unlock" set in Developer Settings of the phone? If not, set it.

Do you run DFS in Administrator mode? If not, reboot your PC, launch DFS in Administrator mode, and attempt to unlock the LTE bands on your phone again using the guide.

---------- Post added at 04:33 PM ---------- Previous post was at 04:22 PM ----------

Try a different PC USB port (try a port in the back of the PC case if you're using a desktop) and plug the phone directly into that port (no hubs or extensions)!

thank you for your input. What do you think about yellow line in the log on screen 1 and 2 - at 16:09:36 - are those normal "errors"?
[LG V10 General] melorib:
when I click Read on LTE BC Config DIV LTE #6829, nothing happens, all bands stay dim and selected like before pressing Read, I have to click on any band to uncheck everything, then I check the same bands I had on LTE #6828 and Write, but next time the same, still nothing happens when checked :confused:

It works fine with LTE #6828 and with both "CDMA/GSM/HSDPA" :good:
[LG V10 General] gbssengo:
I had the same issue, but now that I think about it... I think that was due to the SIM2 being inactive. I can be wrong (i'm going to try tonight), but 6829 requires SIM2 to have a SIM card connected.

UPDATE - Nope that wasn't it. I never got 6829 to work, but my LTE enabling worked regardless.
[LG V10 General] melorib:
Bingo, I also use only 1 SIM :good:
[LG V10 General] rcyh:
So you have to have at least one SIM inserted in order to have the band(s) enabled?
[LG V10 General] rcyh:
I am reporting that I am able to root and enable Bands following Brobro1 instructions. Thanks a lot!

I am from Canada. According to frequencycheck.com, all carriers here are using Band 4,7,and/or 17.

After rooted:

Band 4 - FAIL

Band 7 - SUCCESS

Band 17 - FAIL

After Band enabled:

Band 4 - SUCCESS

Band 7 - SUCCESS

Band 17 - SUCCESS

Then I tested the phone in different areas...My carrier network is Bell which is using Band 4 and 7 LTE. Strangely sometimes the phone picked up and connect Band 17...Overall, I am able to connect Band 4, 7, and strangely 17 in different areas here.

I was going to give a shot to flash back to unroot...but LGUP does not allow me to choose the H961N10c_00_0107.kdz file (only .tot). Any instruction on how to flash back to factory?

Thanks mate. I'll try enable band 2 and see what happens...
[LG V10 General] a_petrov303:
I have 2 SIM all the time, but I did get the same behavior when switch to read 6829 - all dimmed until I press on the screen with the bands, exactly like you described.

The only thing I did not check was to Run As Admin of the DFS software - I really hope this is what I need to do in order to get SUCCESS in field test menu.

Also, on the VoLTE/battery drain discussion - I have noticed that after root, VoLTE was enabled by default - this led to high battery drain for me. I switched it off now.
[LG V10 General] melorib:
I do run DFS as administrator...

How do you enable VoLTE ? I did find it in Modem Settings, in the hidden menu, but press and nothing happens :confused:
[LG V10 General] a_petrov303:
OK, I ran DFS now as an administrator, even thought the guide did not mentioned it. No change at all. Still have fail on all bands.

VoLTE button I saw in the notification panel. From there I could switch it off. So it was enabled by default, I disabled it.
[LG V10 General] melorib:
No VoLTE button in my notification panel, maybe because your carrier has VoLTE, mine apparently doesnt :rolleyes:
[LG V10 General] a_petrov303:
the last option on the right of notification panel is [MENTION=309187]edit[/MENTION]@.

There you can choose which buttons can be visible in the notification panel. Did you tick VoLTE there?

Anyway, it seems like it is game over for me. LTE does not work at all and the phone is showing like there is no sim card every 5 seconds. Also even when the network coverage appears briefly, there is no LTE there. :mad:

Will factory reset help to restore the radio connection or does it only erase user data and leaves the radio info as it is?
[LG V10 General] melorib:
I know about that option ;)

Is your phone on "diagnostics mode" (on DFS second screen) :confused:

Good luck :good:
