Cellular data problem with french carrier on LG V35 AT&T unlocked flashed FI firmware
Hello everyone,
I bought a LGV35 AT&T unlocked on amazon 3 months ago because I was so tempted by it. During the first 3 months with the AT&T firmware everything was fine, but all the crap AT&T apps was bothering me. So, I searched on internet for ways to get rid of the bloats and found out that you could cross-flash to unlocked google fi firmware, so I did. Everything went fine with the flash. Unfortunately, after 3-4 days my phone lose cellular data function. I can make calls and sms but can't have 4G/3G/2G, no cellular data at all. I tried a lot of things but no results. The only thing that worked is re-flash the fimrware but then after 3-4 days I lose cellular data function again. Can someone advise me about that ? My carrier is a french one (SFR). Is it possible to go back to the AT&T firmware again ?
I have a LG G7 as backup, so no worry here.
Thank you in advance for your responses,
Jenfir
Couple of thoughts as a novice I always like to investigate the most simple possibilities?
And as a second idea from the simple side is with the AT&t software if you had this wi-fi connection made automatically perhaps it would be delivering you data through Wi-Fi as opposed to the cellular then once you switch the software it no longer had that automatic connection to all the AT&t hot spots
Hi, thanks for your replies. I have not reach the limit data yet.
I don't really understand the automatic wifi-connection setting. Now that I don't have the AT&T software anymore I don't think it affects the connectivity on my phone. I have doubt about the google connectivity services though. I have my phone running again over cellular data after factory reset and I did not install the app. I will see if it solves my problem. I will keep this thread updated. I still take other advices.

Hi All,
I moved Carrier from Verizon to T-mobile, and found one good feature of T-mobile S5 is not working in Verizon version.
Wifi calling, I'm using Galaxy S5 Verizon, all others are good, except Wifi calling.
Sim error was already handled by rooting and deactivating service.
Is there any way to activate wifi calling feature in Verizon Galaxy S5 version, I searched, but by locked Bootloader, I can't install T-mobile firmware in Verizon version, and also I can't do Safestrap with OG5(with root) rom either.
My Verizon S5 phone is very good in most of area with T-mobile, except my office, by poor T-mobile signal (I guess, there is Verizon router in my office area, and locking my signal, for when I out of office, full t-mobile signal is detected, but when I enter to my office, all dead. , no problem when I used Verizon Carrier )
So I need wifi calling feature at my office, but I can't use it with Verizon version.
If you guys can provide any other recommandation. it will be very helpful to me.
Thank you!!!!!!!
I found the answer from the other thread.

Downgrade to NCG build (Kitkat) by odin again and then rooted.
And then followed guide in the link (I used Flashfire).
Only one thing in Twi5ted Lollipop 5.0 V7, Select "No thanks" to sharing data with Samsung in EULA Screen or will meet sim problem.

In that case to resolve the issue, need to factory reset and then restart initial setup again.
(I did )
Currently my one looks good
Wifi Calling, Bluetooth, GPS and all of other functions working good.

I really wish wifi calling wasn't so locked down on Big Red (VZW). Hangouts dialer is a good alternative as long as the wifi is stable enough.
Hi guys,
I bought the unlocked firmware phone back in December 2016. The phone is great, the problem is I am using EcoMobile MVNO. It's refusing to recognize the network with the MVNO's sim card. I've spent hours on the phone with them and they claim all is OK on their (and Verizon's) end.
The phone sort of works, so I've just been grinning and bearing it so far. Using 4G switcher, I can put it in CDMA only mode, in which case it connects to '123456' and I can receive and make calls, and receive texts, but have no internet. If I put it in full LTE/GSM/CDMA auto mode, it connects to LTE, so I have internet, but it claims I'm not connected to Verizon network and in fact it's not available. So in this mode I can't receive calls or texts. Can't send texts under any mode. I've done a full factory reset at the MVNO's behest, of course that did nothing. The phone seems to connect fine to Verizon's network if I borrow someone elses's Verizon sim. My MVNO sim also works in my wife's iPhone5 without a problem. So it really seems to come down to the firmware on the phone. I'm holding out against hope that when Nougat comes to the G935U firmware, this problem is magically solved... but just in case decided to post here.
Please help, any ideas would be appreciated.

Flash the vzw firmware or go through the steps for the hybrid rom with vzw modems implemented.
Thanks. I was really hoping for something less intrusive, maybe some CSC edit fix, or some such.

Welp, the 7.0 update is here, and it didn't fix my issue, in fact now I can't even get LTE data as I used to get. :crying:
So I had this issue when I first got the nougat update. When I got my S7 I put in my brothers sim card to made sure it worked on Verizon cause i was buying it from someome and anyway I activated my straight talk verizon SIM and everything was great until I got the update and my service was weird and I didn't know what to do and then it dawned on me, I put in an actual verizon SIM card, doesn't need to be active let it register and then put your SIM back in and everything was great! Hope this helps...
Switched to TotalWireless, phone works now. They first sent me a SIM which didn't work, then had to send a different, post-paid one.
I now suspect if ECO also sent me a postpaid based SIM it would start working. Things are always way too complicated when Verizon is involved.

I'm tempted to try this as I'm having the same problem with my 935U and Xfinity Mobile (Verizon MVNO) SIM, instead of connecting to the Verizon network, it connects to network 123456. I did load the 935V firmware, which worked fine, but I'd prefer to return to the U firmware if this would work. Is this still working for you, and if so, do you just need to put the regular verizon sim in once and from then on the MVNO sim will work, and continue to work including after a reboot?

I put in a Verizon SIM in it once and that was after the nougat update. But every time the phone restarts, I have to make a phone call for it to connect to the service or it will just stay stuck in "searching for service" but once the phone call connects, I hang up and everything works as it should.

Thanks, strange problem. I'll probably just stick with the 935V firmware for now as that's working fine (just have the Verizon bloat and failing the hotspot check). I also have a dialog going with Samsung support to see if they're aware of the problem and have a fix.
Hi everyone, so I recently purchased an S7 SM-G930V and I'm having some problems with the mobile data connection and was hoping that someone on here might be able to help me out. I've been heavily researching and trying everything I can find online for 2 weeks now trying to figure out why I cannot get this phone to connect to mobile data and I'm about to give up and use it for target practice.
So here's the story:
I bought the phone from a seller on Ebay (I know I know) and it showed up in flawless condition externally and SEEMED to work perfectly. Upon receipt of the phone, I noticed that my current simcard wouldn't fit so I took the phone to verizon to get the nano sim and have it activated. The guy put the sim in and booted it up but after about 15 min the phone was still saying that it was "activating" so (being in a hurry) I told him that I'd just let it activate and be on my way. About an hour later my phone chimed saying that activation was complete but I noticed that it was showing H+R for a data connection which I believe meant I was roaming? Anyway I didn't think much of it because I was in a pretty rural spot in Alaska and the service was spotty.
Now here is where the problems started. Once I got home I noticed that the phone was not picking up any 4G LTE data at all and was bouncing back and forth between 3g and 1x but wasn't actually connecting to them, just finding them (greyed out). I rebooted the phone to see if maybe it just needed to update the local towers or something but it still would not connect to any mobile data at all so I took it back to the verizon store and they swapped the sim for a new one. Now, the phone will not activate AT ALL. The guy tried 3 different sim cards and nothing. It shows fully connected (5 signal bars) for voice but just cycles randomly between 3g and 1x data and will not connect to them let alone even find 4g lte service. When it connects to the towers it shows Verizon Wireless as the connected carrier but since it can't connect to data, it won't activate. The guy finally told me to call tech support and after about 3 hours on the phone with them, they pretty much told me they don't know what's wrong and to get a new phone.
So I decided to hit the internet and try out every option I could find before just sending the phone back. However, after countless hours of tinkering with the phone including rooting the phone, updating the firmware, factory resetting multiple times, clearing cache, disabling the cell radio and changing settings in build.prop, default.prop, apns_config.xml etc etc and getting nowhere I am stuck. I was really hoping that this was just a software issue or APN/modem/radio band etc issue that I could fix but it's looking like it might be a hardware problem or it's way above my skill set.
TL;DR
Verizon Galaxy S7 will not connect to any Verizon Mobile Data Network and therefor will not activate but it will connect to data while roaming? Any and all suggestions, help or advice is appreciated! Even if it's just to tell me that the hardware is faulty and I need to replace the phone. I just need some opinions from the pros if possible. Thanks guys/gals.
G930V service switched to AT&T, root, firmware, and international service questions.
Hello,
I rooted my S4 a couple years back so I have an idea of how to go about this, but the fact that I have switched carriers has added more layers to my confusion when reading through the how-to posts on the forum.
I have attached my phone info. I have a G930V and I just switched carriers to AT&T. The only downside I've seen is that I can't send MMS.
To summarize my questions:
1) What is the most stable rooting/firmware to date? I have the all the latest updates pushed by Verizon, including the December 2017 security update. Most the guides on this forum are over a year old and trying to read through the dozens of pages of updated responses and procedures is giving me vertigo.
2) Is there any advantage to flashing G930A over G930U to my device? It looks like I can get all the AT&T LTE bands on either firmware and I don't care about using AT&T specific apps/streaming services.
3) Finally, I travel abroad regularly (Italy this year), and I would like to be able to buy a local sim card and minutes and use my device while there. Are there specific things I need to do/not do to allow this?
Any info/point in the right direction is greatly appreciated, I know the guys on here know there stuff .
you need to change your APN to your new carriers settings. Hence why internet ant MMS don't work correctly but calling does. This is because the modem works fine but the data is not getting through to the write network (or something)
google your APn settings for your new carrier and edit your APN in the settings of the connections.
good luck

Thanks, I did switch those settings and I have full functionality except for MMS.
Just as the title says, has anyone successfully used an unlocked, Verizon branded LG G6 (VS988) with a third party sim (for data and making phone calls? Which country are you in, which sim cards are you using, any attempts abroad/traveling, etc?
Bought a mint unlocked Verizon LG G6, confirmed it was unlocked by two Verizon reps over the phone, and one in-person Verizon rep in my city. With the in-person rep (as well as on my own of course), we could not get my T-mobile, Three (a UK sim), and Project Fi to work with the phone, for data/phone/SMS.
Not surprisingly, when he inserted a Verizon Sim, of course it worked. The rep genuinely tried his best to help, but in the end was like "sorry, ¯_(ツ)_/¯ " and said it was probably an unresolveable network problem, and yes, that the phone was definitely unlocked (checked his database).
Before I came to his shop, though, I spent a couple hours at home tinkering with ALL the phone settings (set up a verified APN, toggle global/LTE-GSM-CDMA options, set data roaming ON), and the best I could get was the G6 successfully connecting to T-Mobile for all of 30 seconds (I could surf the web, but NO phone calls), then losing all bars of connection and cutting out entirely. Toggling airplane mode allows you to connect for at most 30 seconds at a time, also, weirdly enough.
What gives? I confirmed the sim cards worked on my other unlocked devices (LG G5, 1+5, Xiaomi Redmi), and I really want to use this G6 here (USA), but more especially, while I am traveling abroad and looking to use whatever country's local sim cards.
Lastly, do you think rooting this phone and installing a custom ROM would help the issue? I prefer not to return this phone because I got a decent deal on it (through ebay's 20% off) and everything else about it is awesome.
Hi
While not strictly the same, I have Verizon LG V20 VS995 with a similar problem with my EE sim which will not register properly and when it does it is only 3G instead of 4G/LTE but keeps dropping off. Where I differ from you is that I can use an O2 sim and get both calls and 4G/LTE data with it. I live in UK. Hope this might help.

My G6 is the unlocked us997, but the wifes is the Verizon Unlocked G6. UNFORTUNATELY I have yet to get her MMS messages working on it for her but everything else works perfectly fine, on TracFone sim (on AT&T network), ... And FYI, only the bootloader unlocked LG G6 can be rooted, all the carrier version, whether they're network locked or unlocked, they're most definitely bootloader locked, thus no root :<P
I got the same phone as you...I live in the Dominican Republic using a Claro chip...Bought the phone from ebay unlocked. So there is something you must talk with verizon so they unlock it. On the other hand we cant root our phones only the europe and US version can be rooted.
Have you checked if this phone has a region locked on it? And if it's removed by placing that 5 minutes-long phone call?
Also, once the SIM (non-Verizon SIM) did you check the APN settings if they are the correct one for your carrier?
I have a similar problem
I bought an unlocked Verizon G6 vs988 on ebay (the listing actually said US997).
I managed to get it to work for phone calls and sms but could not set the data.
I manually set the APN but it would not stay "chosen".
I got all the settings but when I chose it and closed the screen it got unchosen (unchecked) and I did not get a data connection.
is there any custom rom for this model?
would a firmware for the us997 work on this model?

If you are in U.S. it should work fine with AT&T and T-mobile, as long as correct APN has been entered. once you enter the new APN, you must select the 3dots, on top right and save, once the new SIM inserted, just go back to APN and select the correct APN.
If you are outside U.S, the LG G6 Verizon unlocked does not have B1 (2100) which is required by most GSM carriers out side US, so you can get 3G or in most cases 2G (E) network only. LG G6 AT&T unlocked works fine outside US, but it does not have CDMA technology and can't be use with Verizon or Sprint. hope that helps
Hi , I have a similar problem. I bought vs988 verizon version and popped in a MINT sim. I had issues setting it up but eventually got it work via the pull down menu in the 'settings' at the top that said 'mobile data off - turn on?' - now this has vanished- can I get this back ?
The mobile data button in the notification tab and the actualy mobile button in the mobile data section in 'settings' do not work (and never have) - they always ask me to contact verizon.
So what do i do ? I have no mobile data now. And it's a pain.
My issue is partially solved in that when I 'reset network settings' and then re-add my APN (for mint) it automatically turns on mobile data. Using the other 'mobile data' buttons (as I mention below do not work).
And now that mobile data is on - I use airplane mode to turn it off, and turn on wifi (because i have google voice I still get voice calls). Anyway this works if you have a similar problem.
I am wondering if this issue would exist if I used a Verizon MVNO (instead of Mint/t-mobile) ?
(so by it being offically "unlocked" actually is not really true - when i first bought the phone I messaged LG and they suggested i needed to send it into them so it could be re-flashed. They would charge me for it and I would lose my phone for about 2 weeks - which is a pain, and not worth the expense)
