[Q] Unlocking a Sprint LG G Flex 2

Today I went to unlock my Sprint LG G Flex 2 after paying it off. Sprint gave me a code (In a form of ##xxxxxx#) to put in via the dialer, but it did not unlock the phone. They are telling me to go to a 3rd party company to unlock it, but I am wondering what you guys think. I know there is quite a few software loopholes that some people have used on the G3 to unlock it, and I am wondering if any exist with the G Flex 2. Heres whats going on
With a Sprint sim the phone stays on Sprint and works no problem
With a Verizon sim it will use the Verizon voice network but it does not get data
With an ATT Sim it goes between "Service Disabled" and 4 bars, but will not make a call or send a text.
With a MetroPCS sim it will not call, text, and stays at service disabled
With a PTel sim it stays at service disabled
From what it looks like to me the phone is not GSM unlocked. Is there any way I can unlock it for GSM use. I know some bands wont be picked up, but I would like to use it on ATT 3G when im out in the countryside where Sprint doesn't have service. From what I know of since the Feb. 11 revision of laws for unlocking devices if the device is in good standing and paid off/contract expired the carrier is supposed to unlock it, but there method is not working for GSM use. I am wondering if anyone knows a way to get there code to work or a software loophole to unlock the SIM slot for GSM use. I am guessing that the phone is receiving att and Metro service because the split second before it goes to service disabled it gets 4 bars and the phone recognizes my phone number. My ATT and Metro APN settings are programmed in already in the roaming area, but there is not an APN settings input in the mobile networks category.
If anyone knows how and if this phone can be unlocked to work with GSM service it would be a great help.
Thanks
Jake
Also, when I use the the Available GSM networks feature under "Roaming>Avalable GSM networks" it always comes up wit "Error searching for networks"
The phone is rooted, could I use unlocking methods from the G3? How much of a risk would I be taking by using methods sourced from another LG phone? To expand upon that I would attempt using methods proven with the g3 or original g flex to try and get it to start running on gsm, I did submit a domestic and international unlock to sprint but all they gave me was a useless MSL code. I need to get this working on at&t or I will have to sell this wonderful phone.

As far as I know they will only unlock it for a Sprint customer who has the line active for 90 days. Unless something is different on the Flex 2 there is no code to enter, I unlocked my HTC One M8 before swapping to the Flex 2 and everything was done on there end. Additionally they state the unlock is only for international use and will not unlock the phone for US carriers although I cant verify if that is true as I don't have a US SIM card to try.

The phone is fully paid off, it was used for less than a month. In the USA there is a law that was passed on February 11th 2015 stating that all carriers must be able to unlock there phones for domestic service (DSU) as far as I know sprint does not seem to follow that, and makes it dang hard to do anything. I was able to get texts working, and data, but I cannot call or receive mms, anyone have any ideas on why that might be. I would like to try and get both working, and I will put in the work for going into the root and trying to get the bands unlocked for AT&T, if anyone can confirm that it is not a gigantic threat to the phone by attempting it, I would make a backup before, but my last experience with a Verizon S3 + Easy unlocker bricked my phone, and although I got it recovered it was no fun.

Rooted...
You stated that the phone is rooted, was the phone rooted when you attempted the unlock? If so, I would suggest restoring the phone to fully stock via the files supplied by Malxce and method described in cairui505's thread here:
http://forum.xda-developers.com/g-flex2/help/ls996-tot-t3094660
I have used it and it works great. After that I would attempt the unlock as Sprint suggested and follow any further problems with Sprint tier 2 technical support. I'm sorry, I don't have the number handy but I'm sure Google will assist. Tier 2 support has a great deal more knowledge and capability than the store or tier 1 personnel. You are correct that they are required by law to unlock the phone at the users request but they will not make it easy and unlocking the phone doesn't change it's hardware capabilities. I'm just not sure if there is an underlying and limiting hardware difference between the carriers versions that would prevent proper activation on another carrier. The law requires that they unlock the unit, not include the hardware to port to other networks.

How would the phone being rooted stop it from being unlocked? I ask because I bought a used phone from ebay that's already internationally unlocked, I've been given the msl code multiple times by tech support, and as I've just discovered it's been rooted.

AT&T LG V10 on Cricket

Hi,
Just curious if the AT&T Lg v10 would work on cricket? I have been buying factory unlocked phones for the past year and half so am a bit out of loop. I know older att phone models worked on cricket but I did see a few cases of it not working in the newer threads online. Just want to check before getting it.
Thanks

You can buy a locked AT&T V10 and use it on Cricket (owned by AT&T). It does not need to be unlocked. Same applies for any AT&T MNVO too. In theory, but it seems youve found people posting that for them their phones haven't worked...

Thanks man. I know in theory it should work just a bit hesitant since ATT has been having a lot of new restrictions with new android phones like bootloader lock.

All carriers used to be boot loader locked. That's not new. And as far as AT&T and T-Mobile they welcome each others phones, they like stealing each others customers.

Verizon phone cricket service
Wanted to share I bought a Verizon v10 off eBay (they come unlocked out of the box) took it to cricket, tweaked a few settings and it's worked perfectly for three weeks now.

Im using my v10 on Cricket right now and it works well! Just wont get any updates unless you use an att active sim card.

My v10 is from AT&T and I currently use it on cricket.
My GF's v10 is from Verizon, and she also uses it on cricket. She just had to set the apn.

I use my locked ATT V10 on crickets network. The only real issue is so far it can't update to MM since I'm not a ATT customer.

do you have the APN settings correct? if not, enter the correct APN, enable it, then restart your phone. it should work.
you can just slip in the sim card and hope it works. find your APN settings...

Good day. I am currently running 3 LG V10's on Cricket. So far, so good. Make sure you check your IMEI number with them FIRST !

Anyone have experience with the V10 on mintsim or textnow

Will this G5 (H830) work on the AT&T LTE bands?

I want to purchase a G5 and am wondering if will be more prudent to get an international unlocked one for AT&T or get the tmobile version and unlock it. The GSMarena website shows that both phones (the H830 and H820) carry different bands (no 29 and 30 for the tmobile version). Although straight from the LG website both the 820 and 830 show the EXACT same band supports. Thanks!

Don't know yet but I am having a hard time getting my g5 to sim unlock today. T-mobile said it should unlock through the app but it has not worked for me yet even though I met all of there requirements. They said they are escalating the issue. I think maybe they are having technical difficulties with the unlock server. But surely they will figure it out. I will try to report back.

I'm wondering this too. It looks like it should specs wise.

Clear the data on the unlock app and try again, had an issue with a Xperia z3 recently where the app wouldn't allow me to unlock despite being paid off and on the network for over a year, rep said to clear the app data and try again, worked like a charm after trying for three weeks and speaking to 5 different reps who all had varying solutions, one even said she needed to submit a request and id be emailed once approved, last guy was like nope, once it meets requirements its an automatic procedure server side. So I did as he asked and boom!

I've been escalated more than 8 times already.
No unlock yet.
In 10 days I will be already 40 days in the network.
Lets hope this helps.

Finnally got my phone sim unlocked Saturday

I unlocked it though the app seems there was an issue with the unlock server at t-mobile as the unlocked app failed many times. I called tech support many times but finally i got an email with instructions how to unlock it later with the app and i tried it again and it worked. It said "unlock failed: Unlock Approved: Mobile device is permanently unlocked."
I think the unlock failed was a typing error. but it is now indeed unlocked. tech support had to do something to allow it to be unlocked. I would say keep calling support until it works. now I think I must use my old att phone imei# in order to get LTE working? It seems if your phone imei# is not in a whitelist they wont let u access lte network? If anyone knows how to get Lte working let me know pls?

AT&T 4G LTE is working for me
AT&T LTE is finally working for me. Note to anyone looking to use this phone on AT&T LTE the sim you use must first be activated in AT&T phone first , to enable 4G LTE if it is a new sim. Or if you already got a sim in a phone and LTE is working it should work in the phone if you have correct APN settings.
It seems the sim has to be provisioned in a AT&T brand phone with its imei # which i believe is white-listed for LTE on a AT&T server.

Yes my device is now sim unlocked and I am using it on AT&T now.

I am using my T-Mobile G5 on cricket an AT&T mvno. I switched because they have a totally unlimited plan for $70/Mo only catch is they throttle your speeds to 8 megs down on LTE and 4 megs down on 4G. I bought my phone outright from T-Mobile used it for 2 months on T-Mobile prepaid on the $50 plan and T-Mobile unlocked it for me through the app. I had no problem at all getting LTE from cricket once I put in the correct APN settings. LTE showed up within 30 min after number was ported from T-Mobile.

AT&T or T-Mobile for unlocked S8+ ?

The backstory.... Preordered an ATT Note 7 and had many headaches with delivery / billing. I am now living with my old Note3 using Goggle Voice/Hangouts because of my weak signal (all carriers) at home. I'm using a pre-paid Straight Talk plan when away from home.
I've been waiting patiently for the S8+ and now need to decide between AT&T and T-Mobile for a GSM phone. I plan on paying full cash price and having it unlocked to use a 3rd part prepaid plan (Straight Talk or ?).
I considered a factory unlocked phone (Best Buy, May 9th??) but I am told that those will also have a locked bootloader. Up until the Note 7 I always ran rooted with custom ROMS. I became a big fan of Samsung Pay which I think also means a locked bootloader with no root is needed. Of coarse, bloatware sucks. I had good luck with Package Disabler Pro on my Note 7. I will be using my Google number, if only for forwarding to another number. WiFi calling is a must one way or another.
My Note 7 from ATT let me run Mobile Hotspot at the same time WiFi was enabled. This made it easy for giving my Android head unit in my car Internet access. The T-mobile version at the time needed to be turned on and off.
I'm leaning toward T-mobile only because of my bad blood with ATT. ATT coverage is marginally better in my area.

Either and flash the OS on it with ODIN. It is the same hardware so it doesnt matter.

Yes and also if the T-Mobile version is going to have an unlocked bootloader, flashing T-Mobile firmware should allow you to unlock it through the OS.
But it's highly unlikely it will have an unlocked bootloader, although T-Mobile have supported it, I don't think it's happening.

No unlocked bootloaders on u.s.a. Carriers....

I get that if you buy a carrier phone and then unlock it. But what about the factory unlocked phones sold in the US?
I've heard that the bootloader on those phones is also locked, but not from a real good source of info. I've also heard international versions do not have a locked bootloader and do not support Samsung Pay. They also do not support CDMA (which doesn't bother me at all).

If I flash via ODIN does that kill Samsung Pay? What about Knox?

I'm in a similar situation and my first concern is what bands both phones support. Online it seems AT&T covers both GSM providers perfectly. The info on T-Mobile and its bands is extremely lacking. My second concern is the process of unlocking either fully paid off phone for use on the other. I think I can have TMobile unlock it for me but I'm not sure how it works with AT&T. The easiest solution is the unlocked version but thats not even got a release date set in writing anywhere.

As long you are flashing official firmware from Samsung nothing will break. Knox will not be tripped and Samsung Pay will work.

It is my understanding that all US (Snapdragon) phones cover all bands, including CDMA. That means you could even take an unlocked AT&T phone to Verizon. I'm not used to that! It even has LTE-U which TMo is supposed to be soon supporting.
I am an ex AT&T customer. They unlocked my Note 7, and again with the replacement, without issue. I seem to remember there was a wait period at first. 7 or 14 days?
The thing I'm considering is also the VR incentives for pre-ordering. I can tell you AT&T messed up my Note 7 pre-order. They shipped it on the release day by a slow method. I ended up going to a store and buying one outright and returning the unopened one once it arrived. That caused a billing nightmare that I had to call them every months until I finally turned it in and closed my account.

Can you recall where you read the carrier versions support all the bands just like the unlocked versions? All the info I found from the carriers shows different bands on each model.

You're missing what I'm saying... There will be no unlocked bootloaders on any Samsung S8 phones for the USA. You cannot get one from carrier or factory.
I think you may be mixing up Bootloader unlock and Sim unlock....

I do remember that it was a story about FCC approval of the factory unlocked (SIM) phone. Keep that in mind that it may be the unbranded, factory unlocked phone only, but the article did say they were all the same. The locked carrier phones may not be so flexible.
Other things I've found.. Best Buy SIM unlocked does not get the incentives. Best Buy, and their cheaper price, does not seem to offer a T-Mo phone.
The VR incentive is attractive to me, but is not a must have. At this moment, until I can find out for sure if Samsung Pay will work on an international version, I am leaning towards a T-Mo pre-order. But that is me and my preferences YMMV. I have a major dislike for AT&T.
Looking for where I read it. In the mean time this may be interesting to you.

You're correct that it seems T-mo info is evasive.

Hello,
I would like to know, if it posible to buy the Galaxy S8 from the samsung web page (att version), then unlock it and after that flash the unlocked rom flashing it with odin.
Can someone help me?
thanks.

Just ordered the 955F from Clove...
I'm hoping that missing bands won't hurt my AT&T usage much. Or any prepaid sims I may throw in there.
Will see if the 955U info comes out before my phone, and will decide if I want to cancel.

The big ATT 5G scam

So it gets out there....
Apparently AT&T (possibly/probably others) are taking advantage of their network upgrades to force phone sales. I'm currently using an LG V30+ which from what I see of it's specifications is fully compatible with 4G LTE and even 5G NSA and I can see that VoLTE is currently configured too. I've been using it on an AT&T MVNO for years without much issue. When I paid my bill this month, bam! No more data! Over 3 hours with technical support and multiple agents to get my data working again and when asked what the issue was I was told "It's nothing sir just a little update." Last week my MMS suddenly stopped working and nobody has been able to fix it it, the best (only) answer I've received is that my "sim card is too old, it's from 2014, you need a new sim card." Mind you I've had service through this MVNO since 2014 but have since changed the sim card. So obviously I'm tired of this mess right? So I'm switching MVNOs right? Wrong! I go to port my number to another MVNO (Straight Talk) and my "IMEI shows that my phone is not compatible with the new AT&T network". Comment and share.
Edit: Screenshot attached.
I'm also interested in hearing of any comparable phones that are rootable and have TWRP available that show they are compatible this year on an AT&T MVNO. I checked a T-Mobile MVNO and it showed compatible with Mint.
Edit: Look what I found:
These phones will still work on our network after we phase out ... - ATT

Confirmed? See the only LG V30 listed is the AT&T version.

Verizon uses a different method and they are all CDMA, so I think first they deny anything that can use a sim, I did some research on this once and came across the information...
Basically only two types of phones are compatible with the Verizon Network...
1. iphones
2. Androids that were made for the Verizon Network.
So if it's not an iphone or a Verizon phone it is not compatible for their network because they say so. But you're not missing anything as they seem to have the worst coverage of the big 3.
1. AT&T
2. T-Mobile
3. Verizon
According to their own coverage maps.
But now AT&T is starting to play the same game? My LG V30+ is a US998. Maybe they allow the AT&T versions?
Edit: Typo and additional info as follows...
Allegedly Apple pays for this privilege if you want to call it that.
