Now, the real questions begin. Do I try this method again? Do the manual method since I have the unlock token? Do I leave it alone, since it seems I've lost my touch from the days of the devices in my sig?

I feel like for me it may have been a driver issue. My computer is recognizing my device as a qualcomm device, but not specifically a Oneplus. I think I just made a rookie mistake and did not make sure that I had the right drivers installed correctly and working before I jumped in.

That's what I am assuming as well. If you try again after installing the drivers, please let us know how your progress goes!

I do not know about you, but I have a completely dead phone at this point

No you don't hold volume up or down + power for like 30 seconds

It won't show a OnePlus device it will say Qualcomm device

Just did a reboot on everything and ran it again. it looks like it installed, I'm looking at a OnePlus stock boot animation as we speak.

I stopped acting like a rookie and actually made sure that my drivers were working, tried again and........PROFIT! Worked like a champ! Thank you so much.

Glad to hear everything worked out for you! What are your plans now with your device? Are you planning to root and or flash any custom ROM or kernel?

No customization here. I like the stock software on the OP phones. I haven't really done any crazy modding since I got into the Nexus devices, since they just work. OnePlus gives me the fizz like the Nexus stuff did. The Pixel line didn't light my fire.

The stock software of OOS is definitely my preference as well. The Pixel line seemed a bit bland to me, and the aesthetics of the device, don't even get me started.. Anyways, I think I'm going to keep OOS and flash a custom kernel for small modifications to extend battery life and usability. Just kinda sad it prohibits use of the FP sensor.

Also, for anyone concerned about Widevine:
I went from Tmo stock to OOS Stock using this method, and Widevine is showing L1 via DRM Info.

Finished the update process on my locked Tmobile 6T and everything is working great so far.

A couple things I noticed...

1. Download mode doesnt show anything on the screen. If the phone is off and you hold VOL UP+DOWN and then plug in your cord, have your PC sound on so you can hear it connect. The phone wont change. Then you can hit start on the MSM tool. I couldnt for the life of me figure out what I was doing wrong because the screen stayed black. I had to hold VOL UP+POWER for about 15 seconds to get the phone to reboot out of the black screen before I realized that black screen was download mode.

2. I did not have to actually install the Qualcomm download drivers. I even tried and I guess they arent compatible with Windows 10 or something because it wouldnt install.

3. There wont be any progress on the phone during the update. All the progress will be shown in the MSM tool and it will reboot the phone automatically.

Hope this info helps someone. I thought I somehow bricked my phone when I got just a black screen going to download mode.

Lastly, great job to those who figured this out. Tired of Tmobiles slow updates and being so far behind. Now I dont have to deal with that stuff anymore. Amazing job.

So if I did the conversation via the original way by unlocking and all and then run this tool, your saying that we now have a full international conversion pending the next OTA?

i have just converted my tmobile to the international version 2 days ago. I had the phone unlocked and then got the token and unlocked the bootloader and did it the old fashion way . manual update to 9.0.11 and then locked the bootloader again. so my question is, am I as good as this new method or my phone is still not 100% stock international?
is there anyway I can install the tmobile stock rom again and reset to factory version and then do the conversion with this new method? the new method seems like it will convert my phone 100% to international version. uff, I had a really hard time getting the sim unlocked with tmobile. I wish i had waited a little longer. you guys are angels.
So my questions is : do I stay the way I am or should I re-convert through this new method?

TKruzze · Jan 10, 2019

Out of curiosity, for those who have done this conversion, what are you showing for the IMEI on slots 1 and 2? Do they still show the same number?

I was going to ask the same question and you beat me to it.
lets hear the good news.

Yes both slots 1 and 2 show the same imei.

I don't have the T-Mobile 6T, but on top of giving an idea, I wanted to say congratulations!

Now as for an idea, if you guys want to see if OTA updating works, couldn't you guys:

1. do the conversion
2. downgrade with an older msm tool
3. reboot and test software update in the os

That way you won't have to wait to see if it works?

Edit: If you're searching for a downgrade, I've been collecting all factory images and MSMTool for the 6T here: https://www.androidfilehost.com/?w=files&flid=285795

The one that will take you to the original OxygenOS (9.0.5) for the non T-Mobile variant is in the "OxygenOS MSMDownloadTool" folder named "oneplus6t_fajita_oxygen_41_o.11_181103.zip"

so I guess the new method and old method produce the same results except the new method is a lot easier and less headaches.

Worked great! Thanks to everyone involved!

I remember you from the Nexus 6 forums...

Thank you for posting this, I was assuming it would keep L1 but I am glad to see it is confirmed now! Now that you converted, are you able to run the TMobile MSM tool to restore to TMobile's version of OOS? I am wondering if it will show a mismatch.
