Cannot SIM Unlock Brand New Never Activated GM1915 - OnePlus 7 Pro Questions & Answers

I just bought an open box OnePlus 7 Pro on eBay. It has never been activated. I use Ting, who resells T-Mobile. My SIM card works and I can make/take calls. I have cellular data. I cannot unlock the SIM/Network. Called T-Mobile. Spent an hour yelling at them. The IMEI is beyond 'clean'. They have no record of the IMEI because the phone never had an active contract with them. Bottom line is I can't unlock the bootloader because I can't SIM unlock the device.
I tried the TMO to International conversion via EDL boot mode, but it still has Enable OEM Unlock greyed out because the device is network locked.
Is there ANY way I can network unlock a GM1915 (TMO branded) without T-Mobile? The one thing that came up in my discussion with the (hogtied) T-Mobile rep is provisioning the device with a full T-Mobile service plan at (at least) $75 for the first month which would cover the (less than) 90 seconds I need to unlock the SIM. Even that option wasn't something he seemed confident about and I wasn't about to try it on a whim. They (call center people) just have no way of inserting the record into the database queried by the unlock server.
Suggestions?
**UPDATE: I used a beta of Andriod Q from the OnePlus site and have the bootloader unlocked now, but still can't carrier unlock the network.

Someone just posted a guide on how to convert it to internation, this might be what you are looking for.

[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.

unlock code lg stylo T-mobile

hi Lg stylo H 631 t-mobile
ihave code for unlock network but when inter 2945#*631# show nothing
try device unlock for t-mobile to unlock till me is faild
how how can enter code to unlock ??
i have to code NCK & SPCK
You should have an app to request a carrier unlock. If the T-Mobile and the MetroPCS devices are essentially the same I don't see why this would not be the case. My MetroPCS LG G Stylo has the app on the home screen in the folder which contains all of my MetroPCS apps. I've actually been fighting with support about getting mine unlocked prior to the 90 day policy for use when I am in Germany.
I have problems unlocki ng my phone i bought someone off craigslist with a lock. On it cani get some help to google unlock this acct so i can activate my phone
Good luck trying to unlock the Style H631 with T-Mobile. They are a bunch of lying manipulating thieves. My mother bought the phone from T-Mobile 2 years ago, she was paying $65.00 a month ($15.00 included for phone payment). I told her to go with H2O, Cricket or AT&T, which have he best reception where we live. I told her to unlocked network her Stylo, we tried by codes by purchasing from online unlock companies, didn't work. I told her to contact T-Mobile and asked for an unlocked code since she was with them for 2 years and never miss a payment. They told her that she needed to pay the remainder of the phone in order for them to give them an unlock code. She did, it was around $120.00. At the time, they gave her a receipt and gave her a number to call. She called and told her that it can't be done because she already unlocked 2 phones in one year, and they only unlock one phone per year. It doesn't make sense, it was her first time unlocking a phone with T-Mobile, she then replied to them, if you can only unlock one phone per year, then how come it shows 2 phone in one year?
If you are with T-Mobile, you are simply out of luck, and the app to unlock is just an app that will display "device can't be unlock" or something along those lines. Best of luck.

A quick question about T-Mobile's network lock & unlocking app.

Ok, I have a LG G5 H830 (T-mobile) phomne that I built as unlocked from components (case, display motherboard and chin module). I used an H830 motherboard because they can be consistently have the bootblock lock removed. The motherboard was originally unlocked and I did verify that to be true with a foreign sim. After removing the bootblock lock (I like my phones rooted) the network lock came back. Worse, T-Mobile's unlocking app will only work if your phone was at one time using their network. I am in Canada and there is no T-Mobile network here. That sucjs monkey turds, but I can get it unlocked thru CellUnlocker (for a cost).
My question is this: I know of the manual unlocks where you manually enter a code will hard lock your phone after about 10 unsuccessful attempts. As T-Mobile uses an OTA remote unlocking app, does it have the same limits as a manual unlocking scheme?
Would appreciate any experiences you guys had with their OTA network unlocker.

Does model G020E mean the hardware is Verizon and cannot be bootloader unlocked?

The model is G020E, but does not have any Verizon branding on it; everything just says Google. I was told it was a Sprint phone, but I don't know if that means Sprint sold it, or if it was just moved to Sprint network at some point. Either way, the only branding (physical and software) is Google.
When I go into Developer Options, OEM unlocking is greyed out and says "Connect to the internet or contact your carrier." (Connecting to the internet doesn't change anything.)
From what I've read, there's no way to unlock the bootloader on the Verizon version. Does it sound like this phone is in that group?
Also, I've read some people saying that Verizon will unlock the phone after it's been activated for a couple months. It seems like they are talking about SIM unlocking, but I've also seen claims that people got the bootloader unlocked by just waiting the 60 or so days. Anyone have any experience with that?
Thanks

I Googled the model and it said it's an unlocked model. But once you boot it with that Verizon SIM card in it, Verizon will lock you out of OEM unlocking. Remove your SIM card and factory reset. Go through the setup, then try the OEM unlocking again (remember after you flip that switch, you still need to go through fastboot to actually unlock). Then factory reset again, this time with your SIM card installed.
That 60 days thing is definitely SIM unlocking. It will be a cold day in hell before Verizon consciously allows the bootloader to be unlocked.

Fixing greyed out OEM unlock setting on a financed T-mobile IN2017

Hey, so basically I bought a clean IMEI but financed (not by me) OP8 5G UW t-mobile edition, and I'm trying to figure out how to SIM unlock it so that the OEM unlock option in dev settings isn't greyed out. T-mobile support told me to try a 3rd party unlocking service, which is what I'm looking into right now. I'm just thinking of doing it off of some seller on ebay with some amount of reputation, but will this fix the issue of the greyed out OEM unlock setting?
I was in the same exact scenario, just do what I did borrow anybody's T-Mobile sim card drop it in and then use the T-Mobile app via chat with support and they'll unlock it.
