[Q] Best way to Use LG G3 Without Service - Sprint LG G3

I think this is the first time I have posted, even though I have been using xda for years. Anyway I bought this LG G3 from Swappa and low and behold it has an unpaid bill tied to it and cannot be activated with Ting and I don't have a Sprint account. I have no need to activate it since I use WiFi for everything. So I decided to keep it since I got a good deal and didn't want to wait to return and buy another for $50 more. Right now I am stock and have not attempted to root the device. I have rooted every other phone I have had, due to the software being really bad or outdated. This is the first phone I have had every had where I actually like the stock ROM that came with it(probably because of Lolipop and LG really taking Googles design sense.
My problem is that even though I keep the device in Airplane mode with WiFi on, the device of course attempts to connect to a network every time I power on.(I have to click emergency call and then home) Also the Sprint Data optimizer is using about 20% of my battery, probably searching for service it will never find.
So my question is, If I do decide to root the device. What would be the best ROM to use for my situation of no service? I prefer Stock Roms unless AOSP has a remote control, which I don't believe it does. Also do I really need to care whether I am on zv8 or zv4 since I do not have a connection to a network?
Also. Is there anyway to possibly get T-Mobile service on the LG G3 Sprint Variant? Even if it is a slow data connection.
Thank you if anyone has any answers to any of my questions.

You can flash this ROM for GSM and check HERE for the remote stuff and other mods and tweaks.

Removing the ROM of an HTC demo unit AT&T

Hello people
So i my problem is that i have recently baught an htc one m8 AT&T device . and i found that the android that it's running on it, is just for the demo units it's 4.4 kitkat , moreover i have also some issue with the hotspot option and the network choosing option, like i don't have the ability to choose which network to use 2G or 3G or 4G it's all the time 4G .and you all know that the M8 has got already the lollipop android version on April but mine still on it's demo android version
i have tried the hard reset but it did not work also the did the updates for AT&T apps also did nothing.
please if any one can help me out with a solution i will be more then thankful. also may you know that i'm not a professional android developer so if i goona need to have some files please provide me with them or their path
Was the phone advertised/described by the seller as a demo unit? If not, its obviously a fraudulent sale; and you should seek a refund or exchange, rather than messing with the phone any longer. This is not a fully functioning phone without significant mods by you, taking time and possibly even money.
Hard reset just wipes user data, and won't do anything to solve this issue.
Network type (2G, 3G, 4G) is locked out on the AT&T version, as is the WiFi hotspot. You may be able to unlock the bootloader and flash a custom ROM to make this a fully functioning unit. But you may also need to s-off the phone ($25 by sunshine).
Depending on your intention/response to the above comments, I'll be happy to help you more.
Thank you bro for your support. my problem is that i cannot go back to dealer because i'm not actually in the US and thing is i have contacted him by my brother who baught it for me from there, he said he didn't know about that problem till now ,he sent me some pictures of the other htc phones that he is selling and they turned out that all of them are just demo units and not for sell.
While i was looking on the internet i found that rooting my phone and installing a custom rom is my solution after all ,exactly as you said.

Not just any ROM. Since the device is on KitKat firmware, you will want a KitKat M8 ROM. Otherwise, you will have severe bugs, such as extreme long boot time (or no boot), or broken WiFi.

Unlocked LG G5 RS988 WiFi Calling

I'm a cell phone noobie so be gentle. I've got a LG G5 phone that is unlocked and have Verizon service. Is there any way to get the WiFi Calling to function on this phone? A buddy of mine had a LG G3 phone on Verizon and WiFi Calling worked excellently. I figured when I bought the LG G5 RS988 it would also have WiFi Calling as well. I can turn on the HD Voice but there is no switch for WiFi Calling. I did try going into the hidden menu *#546368#*988# and turning VoWiFi to 1 still nothing.
Anyone???
I didn't see it on the stock rom. On a custom rom yeah WiFi calling shows up and you can enable it and I'm pretty sure it works since my data plan allows it and I've made a call on it.

Like I said I'm a cellphone noob... What has to be done to get this enabled? Could I contact LG for a update?
I also wish to have this feature.
I think need to ask LG to enable it in next release?
The crazy part is that the LG G3 has this feature.
I believe that carrier versions may have it. All I know is that custom ROMs have it. If you don't know custom ROMs are basically a different firmware for the phone. It isn't as stable but it's better in some ways. It isn't as good as stock but adds features. Yeah it might need to be requested and brought to LG's attention to bring wifi calling to the stock firmware.

V30 US998 unlocked vs. Verizon version...

I'm probably jumping the gun by asking this question now, before the US998 is available, but I'm chomping at the bit to know...
I'd like to buy the unlocked version of the V30, but I understand from the other forums that I may be giving up:
- Verizon HD calling
- Verizon video calling
- wifi calling
- visual voice mail
In trade I'd be getting:
- potentially 128GB internal storage
- no VZW bloat or branding
- all of LG's backgrounds (a reviewer says big red disables many)
- maybe a working FM reciever (?)
Some of these are important to me, some not or can be replaced.
Can you think of any other differences I should be aware of?

You'll get Verizon VoLTE -- but not Wi-Fi nor video calling.
Yes, you can have Verizon voicemail.
Those answers are based on the carrier unlocked LG G6 US997 released earlier this year, from people who have it and use Verizon. You should go over there and ask some questions. That will be the best predictor of the LG V30 US998.
I pasted some of the answers from actual users below.

Getting unlocked phones working on Verizon is still more difficult than it should be. Hypothesis: reps at the local stores don't get a commission on unlocked activations and do get commissions on carrier phones. If you want to avoid technical stuff suggest calling Verizon and threatening to switch to T-Mobile if they can't get it to work, do not go to local stores.
Regarding voicemail, I went with youmail from the play store. You might also be able to get the Verizon voicemail app working, I did not try that since I do not want any lame carrier apps on the device.

Regarding the fm radio. My Verizon branded G6 has the fm radio enabled, you just need to plug in headphones. It works with NextRadio and the LG radio app that I know of. The Verizon version needed files pulled and edited from xda forums to get LG's app working as it does not come with it preinstalled. It wasn't hard to install. An install of NextRadio from the play store just worked. The unlocked version probably includes the LG fm app. NextRadio is pretty snazzy, while the LG App is pretty bland and basic.
I've worked my mind around most things rooted vs unrooted and the biggest problem I have right now is not being able to turn on hotspot on my unlimited VZ plan. this could cause me to return the VZ version if root is impossible which it appears to be. although rooting a phone and playing with it will wipe out the battery prematurely. I've noticed this over and over. not sure I can live without the hotspot option. will absolutely not pay more to VZ to use my own existing plan.

Rooting a phone has nothing to do with battery life. It's just becoming admin of your own phone. The owner of the phone.
Rooting a phone will let you use your hotspot without carrier's permission.
If you mean custom kernels might favor performance over conserving battery vs stock kernel, you have a point. Which might make you have to charge battery more frequently. Thus shorter battery life over a several years period..
However, that is changing! Newer CPU governors like Alucard do a very good job of balancing performance and battery.
One thing you could do is root and run stock firmware, with an xposed module or app that will let you have your hotspot. Again, root by itself does not affect battery life.

LOL.... trust me. viper4android, hotspots, trying all sorts of mods, and yes messing with kernels, changing OS every other week... battery life will get shot... every time, so yes it will... just comes with the territory.
regardless of how you try to fine tune the kernel to conserve. but I'm ok with all of it. I will just be bummed not to get the $200 card and the VR thing. So I guess I have to decide in the next 6 days how important hotspot is vs $300 worth of stuff.

Did you get this phone? Did hotspot work out of the box with unlimited grandfathered Verizon plan or will we have to get root?

no. it did not. I'm jimmy rigging it by using the wifi extender to trick the hotspot to working but it requires that you connect to a wifi first. data isn't needed on the connect. it's hokey but works almost all the time. so I am now content. LG disabler squashed everything else so the phone is pretty snappy.

Having only used rooted phones for the past 10 years or so, I had a similar quandary, although some of the particulars were different. The arguments in favor of the VZ branded phone were earlier release date, wifi calling, $200.00 discount, and EARLIER RELEASE DATE (I have a thing for immediate gratification). The arguments in favor of the US998 were choice of handset colors and the most important factor: ability to root.
I opted for the VZ LG V30 and have been very hapy so far. As far as the OP's concerns, I can say that the ability to insert a micro SD card eliminates that need for internal storage in excess of 64gb, which is plenty anyway. Also, the LG package disabler (https://forum.xda-developers.com/lg-v30/how-to/guide-make-v30-faster-smoother-t3693083) and the FM Radio apk (https://forum.xda-developers.com/lg-v30/themes/lg-fm-radio-app-download-verizon-v30-t3689294) resolve the bloatware issue and FM receiver issue respectively.
As far as my concerns, the LG package disabler also accomplishes some of the same goals that for which I would want to root my phone. One of the main reasons that I root my phones is too be able to block ads, and I have accomplished that by disabling Chrome and installing Samsung internet beta, as well as by supporting developers by purchasing ad free versions of the apps which I use frequently or finding ad free versions of apps when they are available.
I've mostly gotten over the fact that my phone is silver, especially since it's always in a case anyway.

I have friends who are required to have carrier-branded phones and who cannot root. That's a well written post I'll share with them.
As for color choice I'm hoping LG will sell us the "open market" US988 in black V30+ configuration (or V30+ at all), but I'm becoming skeptical.
Interesting counterpoint, al4d.
There's also the matter of OS update timeliness. And security updates -- do they ever come from the the manufacturer? It seems like only carrier-specific releases get the media buzz.
Lastly, I'm sort of holding out for the Oreo release, just to ensure LG put all their best efforts into it. It would be a shame if 8.0 lands and it's a half-baked mess full of bugs.
Hey @ChazzMatt
Recently I've noticed that I have petty crappy signal and trouble with getting a GPS lock. I remember from the turbo having to flash a modem.
I'm running Stock LG at the moment purely for the camera, is there anything you recommend doing? Ive noticed I cant even change the apn settings.
When I hacked from US998 to VS996, I saw there were more "bars" being shown. Note, however, that "bars" can be changed to reflect different signal levels, so it may not actually be getting more/less signal. If I were careful, I would have looked at the numeric signal, but I missed checking that.
I'm running VS996 on our phones now, partly because of the VoLTE support as well... and all of that is working, so that's good.
I don't think you can flash just a "modem"... but I am interested to hear if this can be done...

Oreo now locks you out of APN settings (it knows what best, supposedly) but you can use an app Shortcut Master or Shortcut Master Lite to manually edit APN settings. Here's how to edit APN using that app. Of course that is NOT the V30 -- but it's still the same technique, and you would want to populate with your own APN information, not what they are using for their carrier. Here are instructions for Verizon on LG V30, at least for MMS.
As for modems, I know there are AT&T and Sprint TWRP flashable modems posted, but not sure about Verizon. You can fire up LGUP and manually flash VS996 modem partitions via DL Partition method, if you want to try that modem. Just UNcheck all partitions except for modems.

Verizon G2 on st att network problems

Hi guys,
I know this is an old phone but I just got an old Verizon g2 off eBay to play with because it is easy to run the apps that I'm wanting to run with it. The only problem is that my service sucks now. I got an AT&T straight talk card and am using it but with it I will have 4glte one second and then it'll have no service whatsoever the next. Also when I loose service my phone number and everything disappears from about phone tab. I've tried as many different apns as I could find. What would be the best was of fixing this problem. I monitored my signal to see what happened when I lost it and it said possibly an escfb issue. The phone is a Verizon vs980, running 5.0.2, rooted and busybox. The only other things that I have done to the system besides install some root apps (mostly protesting) is change the system file on hotspot provisions so I can use the hotspot without Verizon. Thanks for the help guys

[help] [troubleshooting] Alcatel One Touch Fierce XL MetroPCS, unlocked, No Service

So the phone itself, as stated is a MetroPCS branded Alcatel One Touch Fierce XL, and according to metro it is in fact UNLOCKED. It is on the latest update of the stock rom from metro I believe (Android Lollipop 5.1.1 ). so that, as far as i can tell is not the complete issue however I'm wondering if it being from metro is contributing to the issue at hand. I am using Mint Sim/Mint Mobile, they have amazing coverage in my area that I myself experienced for a week, so I'm almost positive it is not a coverage issue. Now down to the bare bones of the problem:
I got this phone about two weeks ago now, bought it in "unlocked" "New, Other" Condition on eBay from the seller Cellfeee. Had to use the unlock app when I got it but it went through fine, with no issues. Fast forward I activate my new sim, put it in the phone and experience great coverage for about a week and a half. Phone was lovely. Fast forward more, around 8:30 pm on August 29 2018 I lost service completely. Start journey into google. I have done the following:
Taken out the sim
restarted the phone
tried the sim in other devices
factory reset the phone
rooted the phone, removed metro apps and apn
done *#4636# I don't know how many times
messed with every mobile and wifi setting possible
the only time I have gotten service back was last night around 10, the phone had no wifi connection and it seemed to pick up a very strong signal that faded while i watched.
I have determined that It is NOT the sim card, I have determined it is most likely not the hardware, the only thing left that I can think of is either the ROM or the modem firmware itself. My question is, do any of you think that flashing a custom rom onto the phone could cure this? is there a way to find the most recent stable firmware for the modem and update/downgrade it to that? I've already cut my losses and bought a new phone through alcatel on their amazon link so it's not like i'm completely screwed but honestly I'm so irritated with this phone and I just want concrete answers/results at this point. any suggestions welcome. thank you for your time.
Edit: The service provider in the top corner was mint while the phone was working. after it began to fail it switched to either no service OR metropcs, now it often says metropcs even when no service don't know if this makes a difference
