So I recently picked up the T-Mobile version of the OnePlus 6T (A6013) from Amazon that was refurbished by Amazon. Based on the reviews, I expected that I would have to unlock the sim with T-Mobile before I could even use it. Now that I received the phone, upon booting, there was no T-Mobile animation, and I was able to pop both my AT&T sim and my (work) Verizon sim, both totally work to my pleasant surprise. Now that I'm digging into the unlock/root process, I'm a bit unsure if my bootloader is still locked and I need to take my phone from the T-Mobile rom to the international rom, or if I potentially can go straight into installing TWRP recovery and flash new ROMs.
Additionally, if I do go to the international rom, will I still be able to use my Verizon sim? That's not as important, but definitely a nice touch since it's for work, and I'd like to not have to carry around 2 phones anymore.
Any and all help would be much appreciated!! Thanks in advanced!
UPDATE:
So I went ahead and tried the update process to take my phone to 10.0, but every time I update it, even when attempting through OOS' local update function, when I try booting the phone, it gives me an error along the lines of "FW version does not match SW version" - does anybody know what's up with this? Can't seem to do anything else and have had to restore it multiple times with MSM Tool. Will going through the 7-day unlock process help rectify this?

Im hoping this phone can work on wind mobile. i did some minor searches but i didnt see anything concrete on making this work.
Right now its on bell network. it was a friend and she was going to sell it since she got a new phone. Buuut im on wind. Its on android 6.0.
Status update.
can easily root with kingroot. but when i try to flash a recovery with flashify it gets an error "boot verification fail" on start up. Disappears then a black screen. i have to pop the battery just to restart it.
Im getting frusterated.

got the d852 the correct one. And the thing is not working. This is also a bell phone and im trying to bring it to wind as the title suggests.
You need to use autorec for the d852 from the play store to get twrp working. Use the one for which ever version of android you're on. If you are on lollipop, use autorec for lollipop. There's also a version for marshmallow. Autorec basically downgrades parts of your firmware to kitkat versions which allows you to use a custom recovery and custom roms.
If you want to use your bell phone with wind, you need to have it carrier unlocked. Easiest way would be to pay bell to unlock it.
alright so if i pay to unlock it i dont have to do anything else to it? cuz bell got d852 firmware while videotron/wind has d852g
Update.
I got twrp on. and wow. its a big problem out of the way. so now the next step is for a permanent root correct? And if videotron firmware is flashed would that bypass network unlock?

i tried following this guide but the device manager wont let me install the .inf file. Anyone have any ideas?
another update. i was finally able to get past the port issue. i was able to finish the steps but im not sure if i even unlocked the bands i needed for wind. And also this phone is locked to bell so when i put in my wind sim it says sim network locked. So...i think this is the only step left. Does someone have a method of unlocking it without paying 3rd parties or bell?
So apparently all you need to do to convert your phones firmware from Sprint to T-Mobile is flash the stock BQK5 firmware (acquired directly from Sammobile) using Odin. After unlocking my sprint phone, I flashed this firmware with a T-mobile Sim installed. The phone booted up and upon it showing the home screen, shortly after it said something about it needing to restart and configure what I would assume is the newly installed T-mobile Sim. The phone booted, and all of a sudden instead of seeing the normal sprint boot sequence, I saw a T-mobile one instead. It caught me off guard because on my screen was Juvemex method of converting an S8 to any carrier firmware. I was both relieved and sad that I did not have to use Juvemex guide. Hope this helps anyone trying to convert their phone from Sprint to T-mobile. Obviously I have not tried that with any other carrier so I can only confirm this works on a sprint phone using the Sammobile firmware flashed with Odin. Good luck and let me know if this method works for you, knowledge is power:highfive::highfive::highfive:
How did you sim unlock your phone first?
I went to a 3rd party site and had them remote into my computer and perform the unlock. Unfortunately due to Xda rules I cannot advertise who it was specifically but I can say a general search on eBay does advertise the same type of service. Once that was done I did what I mentioned in the OP and my phone turned into a T-mobile one. It initially booted sprint which was obviously expected, but then it asked to reboot and then viola, T-mobile stock rom since
As of this point the warranty on it has long since expired (for both Motorola and Target, the place where it was purchased) so we're pretty much willing to try anything to get it working
I've got with me here a G5 Plus XT1687 that, at best, I can describe as being in a state of "limbo". Its bootloader mode can only be set to flashing_unlock and flashing_lock. We've obtained the unlock key from Motorola's tool and have tried fully unlocking the bootloader multiple times following the guide on XDA, but it seems to not want to accept the command fully and remains on flashing_unlock. When I try to relock everything to start over, it gets stuck on "flashing_lock" and won't go back to fully locked. When it's in the flashing_unlock state I am able to flash ROMs and TWRP builds, so technically it's unlocked.... sort of. I'm unable flash SOME things, like new bootloaders or gpt partition tables, but other things will work just fine, albeit with the occasional "invalid signature" message following flashing. But this right here is only the start of our problems.
Having purchased the US retail XT1687 model, it was supposed to come carrier unlocked out of the box. My friend who got this didn't have a SIM when he got it at the time, so he just used it as a WiFi-only media player sort of thing. When he finally got a T-Mobile SIM and put it in, it asked him for an unlock code. This of course doesn't make any sense, because we didn't get this from a carrier, so why would it be locked to anything in the first place. It was tried with multiple different SIM cards, running multiple different ROMs (and even stock firmware) all with the same result: the phone seems to be network locked to nothing at all.
I tried calling Motorola and they said they can't make an unlock code for us since it's the carrier that decides what algorithm to use for network unlock codes... but this phone didn't come from a carrier, so I don't know what to do.
Fixing the bootloader thing would be nice, but my main goal here is to try and remove this nonsensical network lock so my friend can actually use it with T-Mobile. At this point he doesn't want to send it back (since we'd have to pay for the repairs, and he got a cheap LG to use as a primary phone anyway). That being said, we're pretty much willing to try anything to get it working. Any suggestions?
EDIT: just want to mention as well, we've never had a problem with the IMEI being set to 0. It's always been what it originally was
Hoping to get some assistance or maybe even just clarification on this topic...
So, I purchased an unlocked S8 Active with the Sprint branding for use on T-Mobile network. After updating the proper APN settings, I was up and running fine, but wanted to get Wi-Fi calling back, so I flashed over to the latest T-Mobile firmware available at Sammobile - G892USQS3BRG5. Ok, before you say anything, yes, it was stupid to flash a brand new v3 bootloader, but it's done so no going back (to my knowledge). Anyways, flash went fine on Odin 13.3.1, but upon reboot there is the Sprint splashscreen. It even tried to constantly verify the SIM card with the Sprint OMADM app, which I have since uninstalled through adb.
Any chance anyone can provide any insight into this (admittedly minor) issue? I don't really have any major issues other than the aforementioned Wi-Fi calling is gone, and I have to use a third party messaging app due to MMS not playing nicely with the Samsung version. Any help on this would be great, and maybe we can stir up some discussion to help prevent someone else from making the same mistake.
I'm curious where you got the ODIN you used.
I have an S8 Active, but an AT&T version, and need to do the same thing - I want to flash G892USQS3BRG5 onto it for the same reason - WiFi Calling won't work AND I cannot get cell calls when my WiFi is on which has resulted in me missing important calls.
When I tried to flash I got a PIT error using what I think was the same version of Odin (patched).
I'm pretty new at this reflashing stuff so perhaps I did something stupid?
Thanks
So i have the smg935p but i am new to flashing roms and have been learning trial and error. I initially flashed a custom rom to the 9bit amd essentially soft bricked the phone. I did more research and flashed the stock rom(or so i thought) now my software version is G935AUCU8ARJ1. I have since had the phone unlocked by spint but now every sim i put into besides the original is showing invalid. Any ideas as ti what i can do about unlocking this phone to any carrier? I am currently using straight talk which i never wouldve switched if id known about the hotspot issue. Also if anyone knows how to bypass that issue that would also be wonderful. Can i perform this unlock or task of doing such without a computer?

If you previously owned it, you can try contacting Sprint to get it Sim unlocked. You might have better luck finding an unlock service on eBay though
