Issue:

Phone will not stay locked on LTE in Global or LTE/UMTS/GSM mode. When in Global or LTE/UMTS/GSM mode and LTE does connect, it's momentarily and when trying to run a speed test or open a webpage, it quickly disconnects and connects to HSDPA. If switched to LTE/CDMA signal locks in great and data speeds are great however voice services are not available. Any thoughts or advice is welcomed. Thanks ahead of time!

[Verizon LG G4] geoff5093:
What band LTE are you connecting to? I found that here on band 2, I will connect at first, but then it switches back to edge. Seems fine in a band 4 LTE area though.
[Verizon LG G4] taifuller:
I'm in the Raleigh NC area. According to LTE Discovery i'm using Band 4. and I also experience the same. A brief connection while in global or LTE/UMTS/GSM mode then it falls back to HSPA.
[Verizon LG G4] geoff5093:
I haven't found LTE Discovery to report the band correctly, at least in my case. It would say I'm on band 4 on my Moto X, but when using a band 4 only device I would only get Edge, but when I go in a confirmed band 4 area it works fine. From what I've found, most 2G > LTE sites were converted to band 2 LTE. Although since you get HSPA the chances of it actually being on band 4 are higher.
[Verizon LG G4] taifuller:
I'm fairly certain this is a Band 4 area. The latest T-Mobile maps are pretty good about pointing out Band 2 areas. I've since sold the phone and acquired a iPhone 6 Plus which I'm looking to sell to replace it with an international G4 or T-Mobile G4. I was pretty impressed with that phone. If I had to rank my favorites, it's number 2. Nexus 5 is still king of the hill for me. There wasn't a better phone out when it was release for a better price.
[Verizon LG G4] chrisc9000:
did you ever figure this out? samething is happening to me
[Verizon LG G4] taifuller:
Unfortunately I didn't. I sold it and bought one for T-Mobile...... Which I just sold about 3 hours ago.
[Verizon LG G4] geoff5093:
So I tested it out again, and in a band 2 area when I boot up my phone with a T-Mobile SIM, I get LTE for several seconds then it cuts back over to 2G.

Now that there is a new software update for the G4, I wonder if this is anymore reliable. Anyone who took the OTA update in the past few days, can you let us know if it's any better?
[Verizon LG G4] dilligaf56:
Been there, done that...wanted to switch over to T-Mobile, but unfortunately, the VS986 only works with two of their three LTE bands, as you know, and it seems everywhere I went, they were using the one the phone doesn't receive (I'm in southern California, for what it's worth, but tested it on a freeway run up the I-5 to the central part of the state - only got 4G-LTE in a few places). Wound up going back to Verizon :(
[Verizon LG G4] neelagujarpuria:
I'm getting the exact same results in Burlington, VT (T-Mobile band 2 market). I first have to manually select T-Mobile (defaults to roaming on AT&T HSPA+) then LTE works for less than a minute (LTE Discovery says band 4) and then I lose signal when I get signal again, I only have edge. It does this constantly and is really annoying.
[Verizon LG G4] konradsa:
Aww, bummer. :( I was thinking about switching to T-Mobile, but looks like that is not a viable option? So no one has been able to successfully use the phone on T-Mobile, even after enabling bands 2 and 4 only?

This whole plethora of LTE bands, where each provider does its own crap is such a mess, is just serves to lock in customers, since switching phones is expensive. Government should mandate that all phones can work on all US LTE bands, the technology exists.
[Verizon LG G4] ruijay:
I am on the same boat. Everything works on my VS986 on t-mobile network. but I cannot get the LTE to work properly. LTE discovery shows band 4 (not sure if correct though)
[Verizon LG G4] ruijay:
My VRZ LG G4 shows that it has Band 2, 4, 5, and 13. I tried enabling 2 & 4 only, 4 only, 2 only, 2&4&13 only but with no success.

What is interesting is I am coming from VRZ LG G3 and LTE was just fine and never had an issue.

I looked at the VRZ LG G3 LTE bands and I see Band 3,4, and 13 enabled. It did not even have band 2.
[Verizon LG G4] ruijay:
More testing:

When I switched the Network Mode to LTE/CDMA I get constant 4G-LTE & internet is working but my phone cannot place and receive phone calls.

with LTE/CDMA I see 4G at 100dBm and 1X at 120dBm
[Verizon LG G4] konradsa:
Interesting, almost sounds like a bug in the LTE/GSM mode.

I assume when you switch to global mode, voice works but only HSPA, right?
[Verizon LG G4] ruijay:
That is right.

The best internet speed was with LTE/CDMA but no voice or text
[Verizon LG G4] konradsa:
Out of curiosity, what speeds do you get on HSPA in global mode?
[Verizon LG G4] ruijay:
With HSPA/3G I get around 7 mbps download and 1.88 mbps upload
[Verizon LG G4] konradsa:
I think since someone reported before that this used to work the G3, it sounds like a bug to me. I guess we can hope and pray that this will work in future releases, but there is no guarantee of course. Not sure what complaining to Verizon will do, since they are probably not very interested in you using T-Mobile. Of course, you can always wrap the complaint into something like you are using the phone in a different country on vacation and it doesn't work. Maybe a complaint to the FTC could work too, since it sounds like Verizon is required to have their phones unlocked for use on other networks based on some settlement.
[Verizon LG G4] ruijay:
I am tempted to try the guide in here to add more LTE bands:

http://xdaforums.com/g4/general/guide-enabling-lte-bands-t3137818

While some testers said the LTE bands are limited by hardware others reported some success modifying the software. Any thoughts?
[Verizon LG G4] konradsa:
Yes, that would be great. I am suspecting that these LTE bands are there in the hardware (since the unbranded version has a lot more) and are just limited by software. I had a look at this guide before, but I did not have too much time to dig into it further. Would be great to hear how it works out for you. I'd love to get band 17 for AT&T unlocked.
[Verizon LG G4] don_alberto:
Did you try?

EDIT: NEVER MIND..need to unlock bootloader
[Verizon LG G4] ruijay:
Yes I was going to say the same thing.

I tried the CDMA tool and it read my Bands as 2,3,4,5 and 13 but my VRZ hidden menu only shows 2,4,5, and 13. Why is Band 3 not showing?

Anyways, I tried to write more bands but I got the error in the attachment. I guess that is because bootloader is still locked. :(
[Verizon LG G4] konradsa:
Actually, this is what we need http://xdaforums.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059

If someone could figure out how to do this on the Verizon G4, that would be awesome.
[Verizon LG G4] ruijay:
I saw that post already and I quit looking after realizing we cannot do step #2 (install a custom ROM) since bootloader is locked?
[Verizon LG G4] konradsa:
Well, it may be worth a shot, maybe there are some nv editors now that don't need custom rom, only root could be enough. But we don't know until somebody tries.
[Verizon LG G4] don_alberto:
doesn't the nv editor writes into the radio partition or something? I mean, I don't think it's writing something into the system partition which we DO have access too with root. So, i'm not sure it's going to work. Some guy did try this method here
[Verizon LG G4] R.Suave:
This may work. Anyone wanna test it?

[IMG="test?"]http://i.imgur.com/XNZsMyL.png[/IMG]
[Verizon LG G4] konradsa:
Tried that, doesn't work for me. I am on AT&T (Cricket), and I only get LTE when switching to CDMA. What I did now is to set my phone to forward to my Google Voice number when I am unreachable. That way, whenever I switch to CDMA, I at least get my phone calls forwarded. I really only need to use LTE for longer surfing session, e.g. on the bus. For everything else, HSPA should be fine. But I hope this will be fixed in a future version of system software.
[Verizon LG G4] ruijay:
I experience the same thing when I switch to CDMA. I get decent LTE coverage and speed but no phone service. I will try to forward my TMO number to my google voice and see how it works for me until someone can find a way to unlock bootloader
[Verizon LG G4] geoff5093:
I'm really wondering if the VS986 even works on bands other than 4 and 13 reliably. I had gone in to the hidden menu and toggled them all, but when I used a T-Mobile SIM in a band 2 area, I get LTE for a minute where I can run part of a speed test or load an app, but then it kicks right back down to EDGE. On my Verizon Note5 however in the same location, and with the same band support, it works perfectly fine. I'm wondering if Verizon gimped the other bands until they need it, then they'll enable proper support via an update.
[Verizon LG G4] konradsa:
Does anybody know where to file a bug report with Verizon Wireless? This doesn't appear to be an option anywhere.

---------- Post added at 09:38 AM ---------- Previous post was at 09:35 AM ----------

This is unacceptable, since Verizon is required to offer their phones unlocked. This is just carrier locking through the backdoor. All, let's use the following link to file a quick complaint with the FCC:

https://consumercomplaints.fcc.gov/hc/en-us/requests/new?ticket_form_id=39744
[Verizon LG G4] konradsa:
So for what it's worth, I did file a complaint with the FCC now, it only takes 5 minutes. Everybody, please do the same.
[Verizon LG G4] R.Suave:
Yeah, I tested it too and got the same result. It seems he's since retracted those instructions and has provided this. I'll keep you all updated if I hear anything. Thanks!
[Verizon LG G4] dekyle:
Not that we need additional verification of this issue but I'm having it as well. I'd like to use my VS986 on T Mobile too.
[Verizon LG G4] don_alberto:
Yep, Apparently Verizon is messing with the network. I complaint too in the link provided above.

Unbelievable.

BTW - don't expect a Verizon unlocked bootloader. As I understand they almost never do it. I wouldn't expect otherwise.

I think i'm just going to sell this phone and buy a tmobile version.

I bought this phone just because I thought it's going to be supported in Tmobile since the bands match.

So now - whenever you buy a phone it's not enough to mess with the whole bands bull**** now you have to check the provider didn't mess with the firmware.
[Verizon LG G4] neelagujarpuria:
I just finished filing a complaint with the FCC as well. It was painless.
[Verizon LG G4] ruijay:
Filed a complaint as well.

Before my LG G4 VS986, I had the VRZ version of LG G3 and it worked just fine with TMo LTE.

If there is no hope for bootloaders to be unlocked, there will be no hope for us to use this phone with other providers?!
[Verizon LG G4] konradsa:
My Verizon service is currently suspended. So can someone that currently has active service with Verizon please chat with their support and explain the problem to them? This may just be a bug that they are not aware of and will fix then. From what I understand, for the G2 they actually enabled T-Mobile LTE support with a mid cycle software update. On the G3, it was working out of the box. So it would be surprising if that regression with the G4 is intentional, it's more likely to be an oversight or a bug.
[Verizon LG G4] bigt629:
Have you anyone tried this?

I found the following steps on slickdeals thread regarding the LG G4. Have any of you tried this? I'm too on the edge between selling it and keep it (to use for TMobile).
[Verizon LG G4] geoff5093:
This was already posted the page earlier.
[Verizon LG G4] R.Suave:
This is now making the most sense. A couple people are also working on a solution in the LG IRC channel on Freenode at #LG-IRC
[Verizon LG G4] ruijay:
This makes the most sense to me. Thanks for sharing and I hope we get a resolution soon
[Verizon LG G4] konradsa:
Btw, already got a call from Verizon Corporate Office today, they said they are reviewing my FCC complaint. Let's see what they say.
[Verizon LG G4] don_alberto:
And look what happened today. It gives hope!!!

Verizon Galaxy S5 Bootloader Has Been Unlocked

[Verizon LG G4] ruijay:
Good to hear!
[Verizon LG G4] eltrkbrd:
Found this thread from the Slickdeals post on the Verizon LG G4.

Anybody have LTE working for T-Mobile yet on the Verizon LG G4? If so, what method did you use?

I posted a copy of my FCC letter (generic signature) for others not wanting to type one up from scratch:

http://slickdeals.net/forums/showpost.php?p=79438993&postcount=6160
[Verizon LG G4] don_alberto:
good compilation. I hope it will get resolved too. I asked the OP to put it on the wiki but I don't see it's happening.

Wish it could be there since the post on SD is lonnnnnnnnng and I know many bought the device to use with Tmob and att.
[Verizon LG G4] eltrkbrd:
Great idea, let's push to put the FCC complaints link on the lg g4 slickdeals wiki (front page). The thread is crazy long and I'm waiting to where I can say, it's over 9000! Fortunately the search function works well...

There is the method with rooting to enable hidden menu to disable band 13 and make sure 2 & 4 are enabled but according to this thread it seems that there is a service running on android as part of verizon's firmware that cripples the LTE functionality. When I tried adding the APN settings, etc it would connect to lte briefly then switch to hspa then 3g, mms wasn't working either.

However, I did not try the root > hidden menu > band change method. Do the people in this thread that tried that still have a problem with verizon's service causing lte problems on android?

Also, is it possible to remove root and flash completely back to stock to receive Ota updates (although I wouldn't want to)?

My main concern is I don't want to void warranty like when triggering Knox on the samsung galaxy.

Looks like no way to bypass locked bootloader on this phone to load custom ROM, correct?

I love the build quality on these lg g4's, plus how easy they are to repair (youtube jerryrigeverything lg g4).

Too bad about the bootloader and limited root options, etc...

I'll go for the lg g4 over that disposable trash samsung calls the galaxy s6 edge any day... no problem with burn-in on the lg g4 IPS display like with the AMOLED displays on the galaxy's either!
[Verizon LG G4] eigen:
Hi guys

I've managed to installed the LG Hidden Menu app found here:

http://xdaforums.com/v...u-t2822925

I can access it (com.lghiddenmenu) with shortcut master and mess with network settings.

I still haven't been able to get LTE to stick (aside from LTE only mode but that disables calling/sms). Just putting this out there for anyone else that wants to test.
[Verizon LG G4] neelagujarpuria:
I currently live in Burlington, VT which is a band 2 market and my G4 is constantly switching between EDGE, HSPA+, and LTE. This happens in my room with the CellSpot which seems to be providing Band 4 LTE. So I'm roaming in Canada using a T-Mobile (Simple Choice North America) sim in my G4 and I'm getting mixed results here. The phone defaults to roaming on Bell and it mainly stays on HSPA+ but sometimes switches to LTE. When I manually select Telus, I get LTE as long as I'm not in a call, and as soon as I end a call it goes right back from HSPA+ to LTE. This is curious because (from what I have heard) Bell and Telus share their LTE network in this area. Also, when I am on Bell, the people I call complain of horrible voice quality, but on Telus it's good. When I tried the same tests on my Galaxy S4, I got LTE at all times (except for Rogers because of the bands) and got similar speeds during the tests. When using the S4, I have good call quality no matter which network I am on. It seems that the G4, for some reason, works much better roaming on Telus though the LTE tower is the same. It's also strange that the G4 won't connect to Rogers at all even though it supports their bands. For anyone curious, these are the networks I was connected to: Bell (302-610), Telus (302-220), Rogers (302-720). I also get bad battery drain no matter which network I roam on.

Here is the letter I got from Verizon in response to my FCC complaint. Complete BS of course:
[Verizon LG G4] Almighty1:
VZW is actually in compliance with the FCC ruling as it needs to be compatible first... Read the FCC information here:

https://www.fcc.gov/encyclopedia/cell-phone-unlocking
[Verizon LG G4] konradsa:
Yes, I know, Verizon is probably compliant when it comes to the letter of the law. But it's still a very shady move to disable the LTE capability of the phone on another network, even though it's technically capable. In my book that amounts to the same as locking the phone, since data capability has become more important than voice and people won't be able to reasonably utilize the phone on another carrier's network. It's even worse than before, because it doesn't look like an unlocking option for the LTE capability is even available from Verizon, so it's permanent. All we can hope for at this point is that either a bootloader unlock becomes available and we can install a different rom, or someone from the community figures out how Verizon does this in the stock ROM and finds a way to trick it into stopping to do that.
[Verizon LG G4] Almighty1:
The thing is, even the non-carrier models of the G4's don't have all the frequencies. I still wonder how people will get 4G LTE outside the U.S. though since they will be roaming on someone else's network even with a Verizon Wireless SIM and don't the roaming partners use different bands than what's enabled? Is Apple the only one that has all the bands enabled in the phones because atleast it seems the Verizon model of the iPhone 6/6S and newer all seem to have the most bands. In fact, in store displays, iPhone uses that actually as a feature, the most 4G LTE bands on any phone! I do wonder though, when Vodafone Airtouch owned the 46% in Verizon Wireless, were more bands available in hardware than now. On LG phones, can you just flash the radio like you can on Motorola phones even if the phone wasn't and locked bootloader?
[Verizon LG G4] ruijay:
I got a call from VRZ few minutes again about the complaint. I explained to the rep what the problem is and she said she will investigate and send me a response once the investigation is complete
[Verizon LG G4] konradsa:
Great, let's hope you have more luck than me and don't get the same pre-canned response.

I updated the 2 SD threads about the Verizon G4 deal with it and also submitted my own FCC complaint. Will also include below for anyone here to copy and paste.

[Verizon LG G4] ruijay:
I got the same response. :(
[Verizon LG G4] konradsa:
Well, this is probably just their standard pre-canned intial response which I won't accept. I will respond similar to RedStripeE90's letter above. They are advertising the phone on their website as supporting these bands and they are claiming they don't lock phones anymore, but that's clearly not the truth.
[Verizon LG G4] ruijay:
Ok I submitted another FCC with similar to RedStripeE90's letter.

Because of this, I did not get a group message and missed an event yesterday.

Verizon Wireless illegal software lock in violation of FFC Ruling

After I filed a complaint with the FCC, I promptly received an email from the FCC notifying me that Verizon would resolve the issue with me directly.

Then a Verizon Wireless "Executive Relations" agent called me.

I asked the agent if they or someone they know has ever been severely bullied at school during childhood and she replied yes.

I then said imagine after being beat up really bad by the school bullies and contacting the principle, the principle replied to work it directly out with the bullies...

I received some canned response from Verizon Wireless completing avoiding the issue and then the FCC closed the case based on Verizon's word with no input from me.

Actually, nothing was done to resolve the case and Verizon is clearly in violation of the FCC's ruling on Cell Phone Unlocking.

As is evident below, the real issue here is that Verizon Wireless is illegally enforcing a "software lock" on these devices via their custom firmware for the LG G4 by running the verizon.custom.verify.LTE service.

Details here:

http://slickdeals.net/forums/showpost.php?p=79086101&postcount=1826

We can't let Verizon or the FCC get away with bullying us around with these canned responses which are clearly an attempt to evade the FCC's Ruling on the CTIA Commitment regarding wireless device unlocking.

My suggestion is for everyone here is to file a second complaint with the FCC after they close the case notifying them that Verizon Wireless made no attempt to address their illegal software locking practices.
[Verizon LG G4] byteless:
What are the exact wording that you use to explain this to the VZ rep?
[Verizon LG G4] renoob:
Got call from VZW excutive relations, I explained phone specs as advertised on VZW site, LG site.

I stated T-Mobile compatibility indicative of World GSM compatibility.

I explained LTE/CDMA Phone issues, LTE/GSM Data issues.

I emphasized firmware/software issue, not hardware b/c of specs.

I mentioned hearing typical canned responses- "technologically incompatible" was ...bogus

I suggested it was a bug, that perhaps a firmware update would address.

I was told report would be submitted, and I would receive an emailed and mailed hard copy.

No attitude detected from VZW. Perhaps the reports are having an effect... we shall see.
