Note: The title of this guide is Enabling LTE bands, but actually, it's for LTE and for HSDPA bands.
This is something near and dear to me, as I travel the world somewhat and really prefer to have only one phone.
I spent all day figuring out how to add more LTE bands to this phone (I have a bootloader unlocked H815, European version, so please understand that it may not work with other versions, and simply can't even be attempted until you can root it.)
The model I own comes with the following bands:
2G bands GSM 850 / 900 / 1800 / 1900
3G bands HSDPA 850 / 900 / 1900 / 2100
4G bands LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 17(700), 20(800), 28(700)
I noticed, however, in the hidden testing menu (277634#*#, Field Test, Modem Settings, Network Mode), the following extra bands, none of which worked:
WCDMA 800, WCDMA AWS (1700/2100)
Along with the following extra LTE bands(277634#*#, Field Test, Modem Settings, LTE Band Selection), again, none of which worked:
Band 12, 13, 25, 29, 40
The result?
Having enabled all of the LTE bands available in the testing menu, I was able to add WCDMA 800 and AWS bands, along with LTE band 40. Unfortunately at this time, Bands 12, 13, 25, and 29 do not work, even if enabled. However, a T-Mobile radio file might help for band 12 if it's a radio issue, or it could be a hardware difference in which case there's nothing we can do. I really don't know until I can test with it. I'm happy about the extra bands, though, because in the US I use T-Mobile, so AWS helps, and in Japan, band 800 is used. Maybe I'll use 40 if I go to China some time.
So how to actually do this?
Step 1: Unlock bootloader and root. You can find out how to do that in other threads.
Step 2: Install the LG USB Drivers. It comes with the LG PC Software.
Step 3: Download CDMAtool from here: http://cdmatool.com/ A free trial works fine for this.
Step 4: Make sure you have adb, and connect your G4 to your PC. In an adb shell, execute the following:
su
echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable
Step 5: Unplug and re-plug your USB cable. Your phone is now in diag mode (although you wouldn't know any better because you don't get any special device names in Device Manager.)
Step 6: Open DFS which you downloaded from CDMAtool.com Deal with making an account, etc. as you have to get into the software. Close the account window and the actual software will launch.
Step 7: Double click your device to put a checkmark by it in DFS.
Step 8: Click the Band tab. Choose RF BC Config at the bottom. Then, choose read.
Step 9: Make sure your bands are displayed. Check the extra bands you want to add. I recommend against enabling bands other than those mentioned in this thread, but you can try at your own risk (in fact, I'd be interested to see if any work!)
Step 10: Click Write.
Step 11: Click the LTE tab. Click Read. Check the bands you want to add, click write. Then, choose LTE BC Config DIV LTE #6829 at the bottom and repeat the process again there.
Step 12: Sometimes the write doesn't go through, and I have no idea why, but I found it helps to play with your phone for five minutes after writing. Also, I found that even if you're not changing bands, it's somehow necessary to flash HSDPA and LTE bands both in one go before restarting the phone. Otherwise strange things happened like losing bands. I was able to get them back though by re-flashing.
Step 13: Reboot your phone and pray.
Step 14: Go into the hidden menu and test the new bands. If they work, you will see SUCCESS when you press them in the test menu. (277634#*#, Field Test, Modem Settings, Network Mode/LTE Band Selection)
I hope this is useful to any other globetrotters!
That's gr8 tip!
Bands are tied to the hardware. Software tweaking won't add them. Not unless they're already part of the hardware, but disabled and hidden by LG for some reason. But that's doubtful.
It might tell you they've been added, but I highly doubt they'll actually work. But I'm no expert so LG may have done something weird here.
So. I have a T MOUS HTC One M8. We have a Qualcomm LTE radio that apparently has access to Band 12 which is TMOUS new 700 MHZ spectrum.
I am currently on band 4 through LTE discovery. Is there any method for adding Band 12 to this version of the HTC One M8.
What aspect of this guide can be used to add to the HTC One M8 T-Mobile Version Band 12?

The added bands do work (depending on the band) so in this phone's case, two new hsdpa bands and one new LTE band were add-able.
I was able to personally confirm HSDPA AWS working on T-Mobile US. The other two added ones I can also confirm because they are scanning on that frequency when using the LTE Band test menu, although there is no local network to attach to.
With other phones even more drastic success stories exist:
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
But in this phone's case, the hardware supported more bands than were enabled, so enabling them was possible. I haven't been able to get particularly Band 12 working, probably because of either hardware or radio file, but it was nice to enable some other bands and see them work.
@the_scotsman the hardware in this case is able to do it normally, but LG has to pay a fee to unlock these bands which is why they're normally locked via firmware.

I worked with Qualcomm chips before so the software setting enables the bands in software. the_scotsman is correct in that if there are no antennae on the phone for those bands then the OP's guide will not do anything. Seems that the OP has confirmed that for bands like HSPA Band 4 the antenna is present. It could also be that the LG didn't calibrate performance of the phone on those new bands for this model. That all depends on how they are manufacturing this phone which we will never know.
Anyone else tried this out? I use the Canadian equivalent of T-mobile so I would need HSPA Band 4. I'm wondering if I should buy the international version and get the unlocked bootloader or buy the locked bootloader version for Canada.

I actually want to know the same. I need HSPA B4 (AWS). I want to buy LG G4 H15 version. If I can enable HSPA AWS band, then im on board to get this phone!
Not particularly useful as this requires root

Yes but the H815 from Europe can be rooted easily so this is an option if you bought this model of the G4.

I ended up with the Canadian version in the end. Turns out the H812 has all the canadian bands turned on and once you unlock the device you can go from a carrier who only uses HSPA(AWS) to one that uses LTE without any rooting or enabling bands. Seems at least for the Canadian version all the bands for all Canadian carriers was turned on.

Were you in a confirmed Band 12 area? Or did it say "fail" and not even scan it?
If he had a H811 model, Band 12 is enabled.. I had Band 12 LTE when I was in the US in the Maryland/DC Area..
Sorry for late reply. It said 'fail' and didn't scan. This is European H815. It's now bricked because I played with it too much.
Has anyone tried this on the VS986? It seems that band 2 is locked even though it's listed as a supported band. When using a T-Mobile SIM I only get LTE in band 4 areas and not band 2/12.

On the G3 you were able to use the HiddenMenu via a root-capable shortcut app, but now we can't access it as we get a FC. I skimmed this and didn't see the unlocked BL requirement, my bad!
@duraaraa How do you know if they're "working" exactly?
In the field test menu on my rooted H818P under LTE Band Selection, I have listed 1,2,3,4,5,7,8,12,13,17,20,25,28,29,40, half of which say "FAIL" when you tap on them, including band 28, which is LTE700 in Australia (FDD)...yet this phones' specs indicate this works...so I'm a little baffled?!
I don't have an unlocked bootloader (obviously), so I guess that means I'm no hope of performing anything successful in terms of accessing other bands?

Well, they went from saying "FAIL" when chosen, to trying to find a signal. Not being in a Band 40 country, I can't be sure, of course, but my assumption is, since it became the same as all other bands which were to be supported by the phone, by not saying "FAIL," that it would work.
However, if you are sure that band 28 is working on your phone, and it still says FAIL, this opens the door to having more working than I thought, so it's certainly interesting! Sadly, as I mentioned before, my phone is currently unrecoverably bricked, so I have to wait for some kind of way out of the brick to continue this testing. Ironically, I'm going to China in August so I could have tested band 40

The problem I've discovered is band 28 (700mhz FDD) SHOULD be working on the H818P be default/stock....yet after root and accessing hidden menu, still says "FAIL"
Thats a huge worry, as the LG sticker with IMEI (etc) indicates it should work on that band!
Really hope unlocked bootloader is coming soon for H818P. Confirmed in the DUAL SIM thread, that phone *DOES* support 700Mhz bandwith...but for countries that probably have 100% of their population that DO NOT even own or sell this phone. Band 17 is supported, not Band 28 (densely populated countrieslike Aus, NZ etc). @duraaraa
Really need to unlock band 28!

I bought Moto G5 Plus (XT1686) from India and now I have moved to USA.
In USA i am using AT&T. Though this device support LTE ( band B1, B3, B5, B7, B40), but LTE doesn't work for this device in AT&T network and I guess it is because of support LTE band incompatibility.
I want to enable new LTE band 17 & 12 on this device (so I can use AT&T LTE band).
I am looking for detail steps which can educate me to enable LTE band 12&17 on this device.
I really appreciate your time and suggestions.

Download shortcut master
To my knowledge you can't enable or change LTE bands... Assuming this is like previous Moto devices, that information is locked deep in the device in an encrypted partition and messing with it often gives you IMEI 0 (really bad, no mobile radio at all). We tried this with numerous 3rd and 4th gen devices...
My word of advice is don't try to mod your device in this way, best case it will do nothing and worst case you brick it... Pick up a new or used device if you can't live with HSPA+ (assuming you get that). TBH, depending on where you are, HSPA can be faster than LTE on AT&T's network. lol
Thank you Stokerk - Shortcut Master - does not do much - apart from displaying my current values - again, I am looking to ADD LTE Bands.
acejavelin - Thank you - I may decide to live with this brick / It works on Just 1-band on AT&T - my current Moto G4 Play works on ALL Networks (CDMA + GSM) / Will live with this bad purchase !
Great and appreciated rom "MIUIPRO 7.9.xx" by @SagarMakhar . But many people getting volte issue & call drop. Here is workaround and please guys vote the poll so I know this is working or not as it is working fine for me.
Requirements-
Root
Network signal guru (NSG) - https://play.google.com/store/apps/details?id=com.qtrun.QuickTest
Instructions-
1. Open NSG and let it configure itself and grant root access.
2. Open 3 dot menu at top left and select "lock bands".
3. Now select only band 3:1800+ only.
4. And lock it and wait for sometime your phone will be blackout.
5. Power on and select "4g only" for Jio sim 1 in network types from settings.
Note - Don't interrupt the process while locking bands your phone will be automatically goes power off within 2minutes.
Default band for jio - band 3,5,40 ... Lock these 3 bands or all bands to get default.
Profit and volte issue solved.
Disadvantage-
Net Speed may vary upto 14mbps+. But still you can manage to get 1mbps download speed.

First thing is Jio is 4g only, whatever solution provided by you will not solve network drop because lock bend is not solve ROM issue. So provided solution will not work for MIUI PRO, I am using network signal guru from long time to lock band base on area and signal strength to get maximum speed when network signal is low

No way. It's not going to happen. Quit wasting your time and buy another phone that has the bands you need.

Yes, it runs on 4g, but in bands like b5 and b3, but these are not standard here in Brazil, the network with the largest coverage is b7 that runs at 2600mhz,
So it fluctuates a lot between bands and often loses the signal altogether
I've changed a lot in these settings, but it doesn't solve 100%

No, you don't know what a band is. You can't use the test menu to add additional LTE bands. Kindly refrain from posting this idiocy here.
I know what is LTE Bands. 6.1 Plus supports all the bands but the fact it is configured in such a way the user can't change it hence the network switches bands automatically.
The LTE Only option configure the network to the 4G but yes you don't have the option to lock a particular frequency unlike other stock Android devices.
I dont know about other countries but here in India I use Jio 4G with 6.1 Plus my phone locks into 850Mhz , 1800Mhz & 2300Mhz (Jio supports it) simultaneously depending upon the conditions in my location.
The Android one might have disabled advanced band locking (FDD & TDD) feature. I'm not talking idiocy here.
