Sending to oneplus won't be necessary.

You can revert back to T-Mobile firmware with relative ease. I don't remember the exact steps, but you can find the MDM tool set bundled with T-Mobile firmware on the forum.

Also, I remember someone on this thread mentioned that he reflashed the phone's bootloader and get the flashing working. This has its potential risk, please be advised.

Also, I just remember something, did you ever update your T-Mobile stock firmware to the latest version before you start the entire process?

While I was waiting for oneplus' unlock code, the device automatically updated to the latest version of the T-Mobile stock firmware before I flashed to the international stock firmware.

Therefore, this could be the possible explanation for your conundrum, if the latest T-Mobile stock firmware shipped an updated bootloader image and you could complete the conversion after updating T-Mobile stock firmware first.
[OnePlus 7T Guides, News, & Discussion] super michael:
I had this problem at first. This should not happen since the flashing process needs some reboots into fastboot not into OS.

I wrote this a couple posts back:

"1. When flashing the device (Step 7 in initial post) my device booted into T-Mobile start screen for some reason instead of booting into fastboot and continuing pushing images. This was not the case if I booted into Recovery Mode (fastboot -> choose recovery mode with volume keys -> enter PIN -> choose English -> something something fastboot) and Chose "Fastboot" manually. After this the flashing worked flawlessly"

-> source

Does this help?
[OnePlus 7T Guides, News, & Discussion] sat2pc:
I followed your advice and I flashed back the phone with T-mobile rom (hotdogt_11_O.01_190920_repack.zip).

I didn't have any trouble to revert it back.

You asked me if I ever updated the T-Mobile stock firmware to the latest version before I start the entire process.

I can't answer because it's the phone of my son and he doesn't know.
[OnePlus 7T Guides, News, & Discussion] sat2pc:
Thank you but I flashed back the phone with T-mobile rom.

I will tray again in few months when T-mobile will stop maintaining the OS.

I don't understand when you write 'chosse recovery with ....' because on first page of this topic (step 7) there is no choice.

Thank you for your advices
[OnePlus 7T Guides, News, & Discussion] Chxc:
You can do a manual check for update inside OS' setting to confirm.
[OnePlus 7T Guides, News, & Discussion] Chxc:
I believe the writer meant when your device kept on boot into the OS, you interrupt the process by following the writer's steps instead to get your device into fastboot mode again to continue receive the remaining of the partition images.
[OnePlus 7T Guides, News, & Discussion] Bolshevik King:
I did a quick scan of the thread, but I couldn't find the solution. I do everything in the tutorial exactly, using the included ADB etc. Yet I still get stuck when it reboots into the stock recovery. It just says waiting for device and nothing happens. What could I be doing wrong or does it just take a bit?
[OnePlus 7T Guides, News, & Discussion] Chxc:
If your 7T reboot properly into the stock recovery screen by itself during the last flash, then I'm suspecting it could be a driver, cable, port, fastboot binary, or a random combination of those issues. Keep going with the process of elimination and good luck.

However, if your 7T doesn't reboot into the stock recovery screen with the fastboot reboot bootloader command, which is the first reboot of the flash batch file, then you could keep your focus on your power shell and fastboot binary first.
[OnePlus 7T Guides, News, & Discussion] Bolshevik King:
I've tried both my laptop and desktop. One being AMD and the other being intel based. Farthest I get it the stock recovery and PowerShell waiting for device. I've tried every possible USB C cable I have, I sadly don't have the stock OEM cable. What drivers would you recommend using and could I be doing something wrong? Thank you for the help.
[OnePlus 7T Guides, News, & Discussion] Bolshevik King:
I looked at Device Manager while in the recovery upon the first reboot and it has a driverless device with the T-Mobile 7T model number.

UPDATE: Holy **** it finally happened. Turns out the thing stopping me was a random LeMobile driver in optional updates in Windows 10. Thank you all so much in this thread. I was about to tear my hair out. If you're still having issues check in Windows option update for ADB Drivers.
[OnePlus 7T Guides, News, & Discussion] Colorblind:
I had a similar problem. It seems after THIS command:

.\fastboot reboot fastboot

if it hangs it's because of a bad/missing driver. it SHOULD automatically start after that, but for whatever reason the USB device itself was not showing up AT ALL. After some fenagling with MSMtool it eventually popped up on windows and I saw it install the driver. If you have to manually re-enter fastboot you WILL see "'Flashing is not allowed for Critical Partitions"
[OnePlus 7T Guides, News, & Discussion] avaholic:
Hello,

Just received my T-mobile 7t and read on a different T-mobile conversion thread that if you flash a Global rom to the device, you lose the Widevine Level 1 cert.

Is there a method to convert a T-Mobile branded device to a Global version without losing the ability to use Widevine Level 1 services? I'd love to have a clean rom without all of the T-mobile bloatware and especially that stupid pinkish purple boot animation but I don't want to lose the ability to play Netflix or similar services in full HD.

Thanks!

Just one question, Do I have to use MSM tool everytime the flashing fails ? or just try to reflash from different PC or port ?
[OnePlus 7T Guides, News, & Discussion] YousefHadder:
It worked finally, I did so many things but I will summrize the steps I believe solved my issues:

First I made sure to unbrick my device back to 10.0.13 from this link:

https://xdaforums.com/t/op7t-t-mobi...our-device-to-oxygenos.4004005/#post-80909203

Then I downloaded the MSM patch tool from this link: https://drive.google.com/file/d/12y3lO0wIgb2_LSDeVw9x_2C_HjbgZlb_/view?usp=sharing

Then followed the steps in this link to get the actuall latest ADB platform tools:

[Tool] Latest ADB Fastboot and USB Driver installer tool for Windows

All praise and All Thanks to God ADB Fastboot and USB Driver installer tool for Windows, which will always install the latest version. To update the adb fastboot and usb drivers again, just rerun the tool. OS Requirements: Windows 7 and Above...

xdaforums.com

the latest tools where installed in C:\Program Files\platform-tools

from there I rebooted into fastbootD successfully, then I went back to the 10.0.13 Global Rom folder and ran flash-all.bat

and it worked like charm :D

Thanks all for the tips and help.
[OnePlus 7T Guides, News, & Discussion] WafflePaste:
Thanks for the aggregation of steps OP! In addition to the instructions I had a bunch of drivers I needed to install, but I looked those up as they came.

So I got stuck for a day on

as well as booting into the Tmobile OS.

What did it for me was either:

- While in fastboot, change the reboot mode from "START" to "Recovery Mode"

or

- Start in recovery mode and reboot to fastboot mode and then While in fastboot, change the reboot mode from "START" to "Recovery Mode"

On the successful run I was using cmd, but I am not sure if it had any effect (I had tried it a bunch before).

Anyways, once it rebooted it went back into recovery mode and kept runninng the fastboot instructions without issue.

edit: After messing up on the rom and reflashing stock, it didn't work as above. What I did right after the first reboot was hold volume down for recovery. From there it kept flashing just fine.
[OnePlus 7T Guides, News, & Discussion] ryno9100:
Just want to confirm this working as of 6/1/21. I wasn't able ot use the flash-all.bat, as it kept taking me to the TMOBILE boot screen after the first reboot. But copy and pasting each line individually worked for me.

@Chxc , this looks really exciting, especially because some ROMs work better on HD1905 firmware.

[OnePlus 7T Guides, News, & Discussion] k.stahanov73:
The benefits of firmware conversion:

Completely remove T-Mobile app and any underlying software (there aren't a lot, but why not competently gone)

Use dual sim supported by the hardware. You'll need to get a new dual sim tray. Just remember to unlock network lock so you can use other carriers, which is a different but simpler process.

Get on the faster firmware release schedule of stock firmware because it doesn't need to be certified by T-Mobile, which are always generations behinds.
[OnePlus 7T Guides, News, & Discussion] hellotiger999:
I had exactly the same problem when flashing my unlocked Oneplus 7T T-mobile (HD1907) with fastboot. I flashed it in Linux (Debian 11) with stock fastboot. I solved it by simply running "fastboot reboot fastboot". The phone reboots to a different fastboot screen with language selections between Chinese and English. From there I can fastboot flash everything perfectly.

A sim-unlocked HD1907 phone. I obtained an unlock token from Oneplus website (Link) to unlock the bootloader. It took 7 days to get the unlock token.

Get the global fastboot ROM. I got 10.0.9 (Link)

Unzip the ROM and copy the attached shell file to the unzipped ROM folder. Install fastboot by running

apt install fastboot android-sdk-platform-tools

. I use Debian 11 Linux. On Windows it should be similar.

Boot into fastboot mode by pressing Vol Up + Vol Down + Power at the same time. Unlock the bootloader following the instructions from Oneplus.

If you just run the flash-all.sh in the fastboot mode, it will fail with such errors:

fastboot flash aop aop.img
Sending 'aop' (200 KB) OKAY [ 0.022s]
Writing 'aop' FAILED (remote: 'Flashing is not allowed for Critical Partitions
')
fastboot: error: Command failed

In fastboot mode, run

fastboot reboot fastboot

, the phone will reboot to a different screen similar to the recovery with language selections, but it is still in fastboot mode. This is special as you can only run partial fastboot commands. Nonetheless, you can now run flash-all.sh without any issues.

The phone will reboot after flashing, and it runs in the global ROM now!

Another method is using Msmdownloadtool to restore to stock TMO ROM to the latest version. After that everything works in the default fastboot mode now without any issues. I'm not sure why.

Hope this helps.
[OnePlus 7T Guides, News, & Discussion] rwong48:
Thanks, simply reading this helped me. My brain is too used to "fastboot mode" with green "start" being fastboot.

I thought this OnePlus language-selection screen was something else, when it was also fastboot, all this time. It even has a "reboot to fastboot" option! How could it also be fastboot?!

Even the Windows drivers detected it, and "fastboot devices" worked, but I didn't notice it.

I know this is a long time after the thread started, but I flashed the global from fine, but my phone doesn't recognize my sim card. It cannot make calls or receive them or anything dealing with the sim. When I flash a T-mobile rom and check the unlock status in the settings, it says its unlocked. Is it that it is impossible to use another sim card with this phone?
[OnePlus 7T Guides, News, & Discussion] thebitjuggler:
I sometimes get that with success. You likely had to unlock your bootloader before you flashed. So you might get the T-Mobile screen. Just boot backing into Fastboot and then boot into ./fastboot reboot fastboot and run the rest of the commands. That works for me. The thing to keep an eye on if the flashing is a success. Only the one reserve flash will fail, rest should all work.

So where the commands start ./fastboot -w, you likely ran ./fastboot oem unlock before that.

[OnePlus 7T Guides, News, & Discussion] Ren_GoKu:
For the guys who are stuck on rebooting to the recovery instead of fastboot and the process just stops. Now follow this steps .

1. Check the device manager. There is a unrecognized device.

2. Update that through the windows update . Click check for updates . The updates for that driver will be in advanced option>> Optional Updates.

3. After you update then the process will continue and you will have international firmware.

PS After you flashed the Patched MSM and then use the flash-all.bat your system will be wiped and you need to close that windows of flash-all.bat and boot to fastboot and try that flash-bat.all again. I used powershell to do this.

Things i also did, if these above steps didn't work. i downloaded this --->>>>>>https://developer.android.com/studio/releases/platform-tools and then save that content in C: and made that location into Environment variable (to use command like fastboot, adb).

Oh how do I enter that mode?

Is that the mode needed for Mauronofrio fastboot Rom Flasher?
[OnePlus 7T Guides, News, & Discussion] thebitjuggler:
I'm assuming you ran the previous commands, and that at the bold command it doesn't go to fastbootd mode.

.\fastboot -w

.\fastboot flash boot boot.img

.\fastboot flash dtbo dtbo.img

.\fastboot flash modem modem.img

.\fastboot flash reserve reserve.img

.\fastboot flash recovery recovery.img

.\fastboot --disable-verity flash vbmeta vbmeta.img

.\fastboot --disable-verity flash vbmeta_system vbmeta_system.img

.\fastboot reboot fastboot

You should be seeing the fastbootd menu and not the bootloader when you ran the command. It's like Chinese text, and English that shows up. Only in FastbootD can you flash the rest of the images. If you see the bootloader, just run the .\fastboot reboot fastboot again. It will take you to fastbootd mode.
[OnePlus 7T Guides, News, & Discussion] SolaceFZ:
Is fastbootd the menu with the white OnePlus logo with the choice with Simplified chinese, traditional Chinese, and English? Earlier I was somehow able to get into fastbootd mode where the words fastbootd were above the OnePlus logo but I don't remember how I did it. Currently it's still not recognizing fastbootd mode and it hangs on waiting for device. I keep rebooting into the bootloader and go back to fastboot but cannot reboot into fastbootd.

I am at wit's end. Really frustrated right now, do you have any tips for me?
[OnePlus 7T Guides, News, & Discussion] thebitjuggler:
You need to make sure that your drivers are correctly installed. That's typically a problem I ran in if I didn't have the drivers correctly installed. I'm going to assume that you're running Windows 11. You can do it with Windows by installing your drivers which is a bit of a pain. Do you have adb driver installed via WIndows update?
[OnePlus 7T Guides, News, & Discussion] SolaceFZ:
I am running Windows 10 and I got the 'fastbootd' to appear after restoring to an Android 11 stock image for T-Mobile, maybe that only shows in Android 11.

Is this whole process doable in Android 11?

Meanwhile I already have the Oneplus drivers installed, what other drivers do I need?

Thanks for being patient with me.
[OnePlus 7T Guides, News, & Discussion] thebitjuggler:
It still needs to pick up your phone when it is in FastbootD mode. If you run ./adb reboot fastboot and it doesn’t pick up ./fastboot devices your drivers aren’t picking up in FastbootD. In Windows go to updates > advanced options > optional updates and hopefully you’ll see Google ADB drivers or something in the vein there. Then install that update if you can. Other wise let me know what you see.

[OnePlus 7T Guides, News, & Discussion] thebitjuggler:
If you flashed all of the other images in FastbootD mode.

When you reboot your phone it should show the OnePlus logo when starting up. Then you can update your phone from the regular updater to the latest version. It also shows up as 1910 in Windows, instead of 1907.
[OnePlus 7T Guides, News, & Discussion] thebitjuggler:
I got that once when the download was interrupted. I redid the whole process and another time I got lucky with updating, after restarting the update, etc. I would go the official update route. I also think you may want to try the https://play.google.com/store/apps/details?id=com.arjanvlek.oxygenupdater&hl=en&gl=US but I haven't used it, and cannot vouch for it personally.
[OnePlus 7T Guides, News, & Discussion] SolaceFZ:
Hmm I used an alternative method as some of those commands gave me some unknown partition and sometimes cannot access critical partitions error.

Can I manually just flash it to the global Android 11 stock image?
[OnePlus 7T Guides, News, & Discussion] thebitjuggler:
Never flashed it via MSM. Update always worked for me. It got stuck a few times, and I left it after pausing, then restarting the phone a few times. Other times it upgraded without any hassles. So wish I could give you better advice. But yeah maybe have a look at the oxygen updater tool.
[OnePlus 7T Guides, News, & Discussion] thebitjuggler:
It worked perfectly for me just using those commands. That said I did my flashing mostly in Manjaro, but also did it on Windows 11 once. But didn't run into any problems. .\fastboot flash reserve reserve.img is the only command you should get that fails as far as I can remember. Did you reset your phone with MSM to lowest version supported by T-Mobile for OnePlus 7T?
[OnePlus 7T Guides, News, & Discussion] SolaceFZ:
Yeah, 10.0.3 was the lowest I could go.
