Yes sir. Local update or through TWRP, the choice is yours.

so i converted my tmo op6t to the int'l oos. my phone is permanent unlocked from tmobile. do i still need to request the unlock token to root it with twrp and magisk? ? https://support.oneplus.com/app/ans...-bootloader-for-oneplus-6t-(t-mobile-edition)
[OnePlus 6T  Guides, News, & Discussion] Caltinpla:
No, you can just unlock your bootloader using fastboot command: fastboot oem unlock, then install TWRP and Magisk of your likings.

But I would still request the unlock token if I were you just in case! ;)
[OnePlus 6T  Guides, News, & Discussion] MidtownHD:
You're mixing up Sim Unlock & Bootloader Unlock. Your phone was Sim unlocked by T-mobile. You need to unlock your bootloader to root and get twrp/magisk. If you just converted to Int'l oos 9.0.11 you can just use Fastboot to unlock the bootloader, no need to request token from OnePlus.

Interesting, mine is not greyed out. Just converted to int 9.0.11 yesterday and local upgrade to .12. I just toggled the OEM unlock, didn't actually use fastboot.
[OnePlus 6T  Guides, News, & Discussion] ysfk7:
sorry, i am still new with the android world. been iOS user for the past 10years.

1. updated to OOS 9.0.12 yesterday

2. enable OEM unlocking from Developer options.

3. entered fastboot by powering off the phone, hold power and vol down and select "reboot to fastboot"

4. then i typed "fastboot oem get_unlock_code", but its stuck on "< waiting for any device >"

not sure whats the next step
[OnePlus 6T  Guides, News, & Discussion] MidtownHD:
4. type fastboot oem unlock - it will wipe your data.

If it doesn't work, go back to 9.0.11, then fastboot oem unlock, then local upgrade to 9.0.12

use this process instead: https://xdaforums.com/oneplus-6t/how-to/t-mobile-6t-to-international-t3888307

[OnePlus 6T  Guides, News, & Discussion] imrock666:
Do you think is something that has to be with the method conversion? I used the other method (the patched one in different thread) and everything was successful. I updated manually to 9.0.12 with Oxygen Updater and I have OEM unlock toggle working good.

Any thoughts?
[OnePlus 6T  Guides, News, & Discussion] Demonface.24:
I originally flashed my device when this thread first came out, would I be able to do a Local Upgrade? If I do a local upgrade would I then be able to do OTA updates?

EDIT : I'm not rooted
[OnePlus 6T  Guides, News, & Discussion] DrRyder:
So I, too, flashed my phone from the TMO software to 9.0.11 with the conversion. However, I have not done ANYTHING else. I did not unlock the bootloader, didnt put on TWRP, no custom ROMs, Kernels, root, etc. I see that 9.0.12 came out. But I dont see that there is a zip to use through local upgrade for that. Would it be safe to use that method when there is a partial upgrade zip for 9.0.12 or am I stuck on 9.0.11?

I don't want to have to unlock anything to update. I checked for updates on the phone earlier and it just said I was up to date.
[OnePlus 6T  Guides, News, & Discussion] TJSteveMX:
Local update is fine, even if you're not rooted, just make sure 9.0.12 is the whole rom and not the partial update, meaning the 1+ GB file

Yes, I normally download the entire file from oxigen updater app from Playstore (you can also download it here on xda under guides thread), once downloaded, I go to settings/system/system updates and do a local update... All should be good, I flashed mine through TWRP but my neighbor did the local update and he is in the same situation as you.
[OnePlus 6T  Guides, News, & Discussion] DrRyder:
Did the local upgrade using the Oxygen Updater to get the incremental update to 9.0.12. Worked perfectly. Didnt need the full ROM, just the partial one that was about 138 MB.
[OnePlus 6T  Guides, News, & Discussion] drahmadzia17:
I'm no longer able to re-lock my bootlaoder. Previously I locked it on 9.0.7 or 9.0.11. I don't exactly remember. This time I'm trying it after flashing 9.0.7 but it says that "your device is corrupt and will not boot". Any suggestions? If someone knows definitely that it would work after 9.0.11 then I can try that. Any help would be appreciated. Thank you
[OnePlus 6T  Guides, News, & Discussion] pmenon53@gmail.com:
I just recently converted my tmobile oneplus 6t to the international version using this method. i have the bootloader unlocked. i thought i would root and install custom recovery, but i just decided to stay with this internation version of OOS and would like to just lock the bootloader. is it possible? i have seen in forums that by running "fastboot oem lock" could cause bootloops? can anybody comment please?
[OnePlus 6T  Guides, News, & Discussion] drahmadzia17:
It was possible as I have stated in my previous post but it's not getting locked anymore. The unlocked bootloader bothers me so much (I don't know why) that I'm not converting to the international rom. One problem that I face with unlocked BL was that I was not able to download and install any app from play store. Either it never gets installed or takes unpredictable time.

Please someone come up with re-lock the BL method.
[OnePlus 6T  Guides, News, & Discussion] MidtownHD:
Last resort would be to use the msm tool again and re-flash.
[OnePlus 6T  Guides, News, & Discussion] pmenon53@gmail.com:
You mentioned that you were able to lock the bootloader earlier but now you are not, has anything changed with the recent conversion?
[OnePlus 6T  Guides, News, & Discussion] drahmadzia17:
The only thing I did different this time was I unlocked the bootloader with OnePlus Rooter instead of flashing Unlock Token for T-Mobile. It showed phone status unlocked but when I put the command "fastboot oem lock" the response was "flash unlock token first". So I flashed token and then put lock command again and it said that phone is corrupt.

Now I have flashed again and again with T-Mobile MSM Tool but it's not working.
[OnePlus 6T  Guides, News, & Discussion] pmenon53@gmail.com:
You may want to download the unlock token bun again and then flash. If that would make a difference?
[OnePlus 6T  Guides, News, & Discussion] Demonface.24:
If I update to 9.011 via local upgrade, would I then be able to do OTA to 9.0.12? if it's not possible, how would I go upon doing that?
[OnePlus 6T  Guides, News, & Discussion] free4flight:
all files were unzipped into the adb folder, including images.zip and the other one, then double clicked on the bat file, started to install all files, as far as I know it was done, it said push any key to continue and disappeared... how long is it supposed to take? appears to continue to go to that crashdump mode with a bunch of options... what should I do?

edit, all the files in the folder are 5.92 gb
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Shut down, unplug, hold volume up and volume down then press the power button to go to fastboot mode. Let me know when you're there...
[OnePlus 6T  Guides, News, & Discussion] free4flight:
I am back to fastboot...
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Show me a screenshot of your working folder before we attempt to flash again please.

Edit: Once you verify all files are where they're supposed to be, run the flash-all-partitions.bat again and this time, don't touch anything until you see that final pause command and final file flash similar to my illustration on the original writeup.
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
You might want to change the first post to read flash flash-all-partitions-fastboot.bat

You could remove the other two bats that are called in flash-all-partitions.bat, the ones that flash persist and criticals.

It seems that the script isnt continuing on after it calls the flash-all-partitions.bat script. Which we've known cause we're not flashing those partitions yet.

I noticed when that guy that bricked his phone, it actually was running the persist and criticals. But I don't think the files were there. Still its possible to clear those partitions when the file isn't present, which is just as dangerous as flashing the wrong file.

I'm sure at some point when fastboot stopped working, he actually flashed abl. But the real question is if it actually flashed, or if the bootloader partition is now empty.
[OnePlus 6T  Guides, News, & Discussion] free4flight:
sorry, having a problem getting screenshot

well, hell, I have the screenshot, but hot to get it here to this thread....???
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Most recent occurrence of this is currently in fastboot attempting a second flash, therefore its still there.

Edit: I agree, I'll adjust to the fastboot script, though I'll test first if that's sufficient.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
run the flash-all-partitions-fastboot.bat and let me know what results you got.
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
Yeah, that just means the script didn't continue. But in the video that guy posted it DID continue.

You're telling users to use a file on the basis that it errors out and doesn't call the next two scripts. You could skip that step and just tell them to flash the file that's actually being run.
[OnePlus 6T  Guides, News, & Discussion] ozzmanj1:
Quick question, just to confirm. I ran the bat script according to the tutorial. I got the following error a few times:

"invalid sparce file at header magic"

Now I did see that it would state during the flash that it is not an error, but want to confirm that it is fine? I proceeded to flash my phone and I did see it flash partitions a & b as it went through. Whole process took probably 10 minutes (did not exactly count)

Is this normal? If not I have not rebooted and am still in fastboot mode.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
I agreed with you, lol... Just a sec, want to get necessary screenshots.
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
[emoji106]

Missed your edit.

It won't ask to clear data anymore.

But after they flash the rom, they can hold down vol- +power and then select wipe cache/data. Should give the same results.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Actually it still asked to clear data, lol.

First Post edited, thanks for the suggestion.
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
Great! Im mobile and don't have the script in front of me. Couldn't remember which one it was written in.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Error is normal, yes it takes about ten minutes, did it say pause? Once it says pause before press enter to continue right after flashing I believe logo is the last image, hit power to reboot, check the image in the first post for reference purposes.
[OnePlus 6T  Guides, News, & Discussion] ozzmanj1:
So while still in fastboot should I use the following command (from your revised tutorial just now:

4. Once in fastboot run the bat file called flash-all-partitions-fastboot.bat

Again, before I was getting the head error and want to make sure that it was noral and I am good to reboot, or should I rerun it with the new tutorial command?
[OnePlus 6T  Guides, News, & Discussion] majortaylor:
Once we convert to the international rom will we be able to then follow the regular upgrade procedures for the international version from here on out or will we always need to side load the newest rom to avoid a brick?
[OnePlus 6T  Guides, News, & Discussion] ozzmanj1:
We will need to go to developer settings and uncheck "allow auto updates" If we ota it could brick, is my understanding
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
You're good, run flash-all-partitions-fastboot.bat

Do no do anything until it says pause and looks like the reference image in the first post.
[OnePlus 6T  Guides, News, & Discussion] 67BGTEV:
I've flashed with fastboot script to 9.0.10. Did a local update to 9.0.11. I'm still waiting on my 9.0.12 notice. So far no luck.
[OnePlus 6T  Guides, News, & Discussion] TJSteveMX:
is possible to do a local update yes, but depending if you're using stock or custom recovery.

on stock recovery you can easily use local update, you will lose root but there is some ways to root without a custom recovery.

if you're using a custom recovery (like TWRP) then a local upgrade may give you a bootloop.

i heard you, you can still find the latest firmware here on XDA on Funk Wizard's thread.

and for the guy that only used the incremental update on his phone; is good to know that it works but i suggest to continue updating the phone with the full update instead, we don't know when that can give you a soft brick like before. luckily we have the MsmDownload tool just in case something bad happens.
[OnePlus 6T  Guides, News, & Discussion] Demonface.24:
Okay so OTA updates would work ?
[OnePlus 6T  Guides, News, & Discussion] edy6401:
I flash to .12, for some reason my phone keeps rebooting. I cleared cache, but it just randomly reboots on its own, even if I am not using it any ideas? I really don't want to wipe it again since I can't seem to get a good back up, and it takes for ever to set everything up again.
[OnePlus 6T  Guides, News, & Discussion] pmenon53@gmail.com:
Try download the full OTA file of 9.0.7 and do a local update of the same again and then fastboot oem lock should do it. Backup your data before locking. I was able to fix mine by doing the same for 9.0.12.
[OnePlus 6T  Guides, News, & Discussion] drahmadzia17:
Thank you, that sounds a better idea, I will try and let you know :)
[OnePlus 6T  Guides, News, & Discussion] feezler:
The OP does not mention that 9.0.12 is safe. Does anyone know if it's safe to do the local upgrade from 9.0.10?

It's been more than a week since 9.0.12 was released and no OTA update available for me. I've tried VPNing to Germany, Canada and other countries as well, but no go.

So I did the backup before flashing, is the UserData.img really necessary if im just going to do a Full Wipe after restore?
[OnePlus 6T  Guides, News, & Discussion] feezler:
Has anyone who is rooted done the local upgrade from .10 to .12 or .11 to .12? I am on stock recovery just rooted. I understand I will have to re-root afterwards but really want to get updated as I am still on .10. Thanks for the help!
[OnePlus 6T  Guides, News, & Discussion] Josh McGrath:
I did both. I did the 10 to 12 then I broke my phone and had to file an ins claim. I got the new one which was on 11 and went to 12 and had zero problems with both
[OnePlus 6T  Guides, News, & Discussion] feezler:
We're you rooted when you did the initial flash?
[OnePlus 6T  Guides, News, & Discussion] Josh McGrath:
Yes, I was rooted on both
[OnePlus 6T  Guides, News, & Discussion] Josh McGrath:
I feel like I should note that you have to install magisk and twrp again after the update, just in case you didn't know. ?
[OnePlus 6T  Guides, News, & Discussion] feezler:
Thanks for that. I can confirm I was able to update with root via local upgrade to .12. Went pretty smooth. I had to uninstall Magisk manager once I rebooted and then re-installed. Now it's all working. Rooted on .12 with Magisk 18.1
[OnePlus 6T  Guides, News, & Discussion] teradark:
So I'm might be going crazy but I can't get to the site

OnePlus.com/unlock_token to request a unlock token. Or is it just me.
[OnePlus 6T  Guides, News, & Discussion] ssinghvi:
Just checked. Worked for me. Was able to login and view my prior application to unlock as well.

Here is the link I used - https://www.oneplus.com/unlock_token
[OnePlus 6T  Guides, News, & Discussion] teradark:
Thanks, it started working for me. Its weird that i talked to the people at OnePlus.com and they kept directing me to the T-Mobile website to obtain a unlock token.
[OnePlus 6T  Guides, News, & Discussion] :
Bc even almost five months later they(OnePlus people) still don't understand wtf is going on. Only 5% of the staff I have dealt with understand the unlock tokens.

[OnePlus 6T  Guides, News, & Discussion] azulay4u:
Hi all,

Since this guide is a bit old I have some questions.

I had the tokens from oneplus long time ago and i just didn't had the time to do the all process of flashing the international rom and mgstick however the time is here since I need to use to dual sim I will go over and do it.

Right now I'm running the stock t-mobile version 9.0.4.

Should I still follow the steps in this guide to flash the international rom?

What rom should I use that is stable?

Can I still use the rom that in this guide?

Thank you
[OnePlus 6T  Guides, News, & Discussion] :
Enable oem unlock

Reboot bootloader

Fastboot flash cust-unlock drag and drop unlock bin here.. enter

Should say unlocked

Fastboot oem unlock

Vol down to unlock bootloader

Let it reboot to a screen it's wiping all data

Then it reboots again

Hold power and volume down till it boots back to bootloader

Flash the newest fastboot rom, ob8 is most stable

Or here u fastboot boot twrp.img then flash a custom rom...rom, twrp, magisk, reboot.. then back to twrp, flash gapps and magisk.

U can also flash any actual ota zip from twrp
[OnePlus 6T  Guides, News, & Discussion] azulay4u:
Thank you for your answer but can you be more clear with the steps?

fastboot rom, ob8 - where I can download it from?

All my previous opo phones were rooted looks like this time is harder
[OnePlus 6T  Guides, News, & Discussion] :
What do u mean? U find ob8 fastboot here in the xda forum. Under that thread under this device.. I'm not going to spoon feed anymore than I did. Those are the steps you can easily find the files. Not being a d I c k but that's the no brainier part man.dont be modding your phone if u can't find files needed in a forum as user friendly and clearly titled appropriately. Tmo op6t is the same device as the international op6t, so all of those files are the same. U can also use anything in the op6 threads if u modify the updater script by adding a "T" anywhere u see op6..

Lastly, root is the easiest thing in the world anymore.

Once u boot twrp u install the magisk zip. Sometimes with pie u must flash it twice but only if u are installing something via twrp in that instance, flash rom, twrp zip, magisk reboot. Then after boot, reboot to recovery flash magisk and gapps.the first magisk flash enables boot after flashing twrp, u will not boot unless u flash magisk.the second flash of magisk actually roots your device. Magisk is an encryption breaking mechanism as well as root exploit. And remember this rule of thumb, root is in the kernel now not like SuperSU as it was mostly a full system root. This is not..root is in the kernel, Aka boot.img. that is kernel,the software that allows communication between hardware and software... A rom or ota update zip or anything that flashes a boot.img will require u to flash magisk again to root. Say if u are rooted and flash a new rom, now u must reroot so flash magisk. It's easy. U flash the zip and tadah.done. hope that helps. If I were you u would make sure to have a healthy understanding of what u intend to do, and know as much as u can about it and be sure u can recover from a brick and know how to use msm tool. Also, I would be sure to understand a/b slots. If u install a zip, it flashes it opposite to the slot u are running. Msm is the firehose to any brick. We have two, one to make your device how it was out of the box from TMobile and one to convert it international. I would learn about everything mentioned before doing anything
