You can go to .11 and relock

[OnePlus 6T  Guides, News, & Discussion] gbzygil:
so i flashed tmobile to OOS and then did a local upgrade to 9.0.11.

If i relock the bootlocker, it does a wipe and i go back to tmobile ? or would it get bricked and i'd have to do MSMDownloadTool again to flash stock ?

Excuse me if this sounds like a noobish question.

I'd like to be on latest 9.0.11 and have certified device to be able to use google pay on my tmo phone.

Once unlocked and converted, can we flash the official TWRP available for the Internation 6T and then root by flashing Magisk?
[OnePlus 6T  Guides, News, & Discussion] :
Thats the best way. U can simply unlock your bootloader, flash twrp and flash magisk, but tmo software kinda sucks.
[OnePlus 6T  Guides, News, & Discussion] CoolRalph:
so maybe im wrong but isnt relocking the bootloader after upgrading to 9.0.11 just going to be a bigger pain when you want to jump to the next update? or is it possible to update after relocking bootloader (through TWRP or otherwise) and im just out of the loop since i havent done this in a while :eek:
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
You can flash the official twrp and/or root with magisk regardless of which variant's software you're on.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
You can do local updates while locked.
[OnePlus 6T  Guides, News, & Discussion] DJBhardwaj:
Thanks. But we will need to update manually every time an update arrives for the Intl OxygenOS, right?

---------- Post added at 09:41 PM ---------- Previous post was at 09:41 PM ----------

Even on OxygenOS provided by T-MO?
[OnePlus 6T  Guides, News, & Discussion] :
Most of us just download the updates, place in internal storage and use local upgrade. Then i reflash twrp and magisk.

Hi, just a quick question as I'm new to this and want to do it right the first time.

Does it matter what version of the TMo software I'm on before going International? I got that garbage Tmo update yesterday that broke Play certification/Pay which was the final straw, and just want to make sure I don't have to roll it back to a specific version before following the guide. Appreciate the responses and patience as a newcomer. Thanks, and great work everyone.
[OnePlus 6T  Guides, News, & Discussion] lendawg:
Shouldn't matter as long as you're bootloader unlocked.
[OnePlus 6T  Guides, News, & Discussion] Caltinpla:

The general guide can be very intimidating for someone who is using the fastboot method for the first time. I understood the concept but I just didn't know how to figure out the omitted details. This above post helped me simplify all and I was able to convert and update my tmobile phone to a the global 6T version and then relock the bootloader. All went perfect and I am a happy chappy.

[OnePlus 6T  Guides, News, & Discussion] bigjailerman:
So what is the benefit of people are relocking the bootloader?

I paid off the EIP contract and I was able to change the slider to enable oem bootloader. Do I still need to get a token or an I ready to move forward? I just from a opo 5 unlocked and things were easier lol. Also what is the best link/tutorial to get into international, assuming 9.0.11 to get on BETA again or possibly going to xXx? Also I read some posts up that the international supports 2 Sims, so can I just swap out the single to dial tray?

Thanks guys .. I'm familiar with fastboot but I'm a bit rusty and thanks in advance
[OnePlus 6T  Guides, News, & Discussion] joemossjr:
The benefits are working drm (Netflix) Google pay and getting otas
[OnePlus 6T  Guides, News, & Discussion] guywong:
When you said getting OTAs, do you mean incremental OTA or do you mean loading a full OTA ROM using local upgrade? I was under the impression that loading the incremental OTA will break the T-Mobile variant.
[OnePlus 6T  Guides, News, & Discussion] coolmaster121:
Well, after the last Tmobile Update, I bit the bullet and switch over to the OOS ROM.

Some feedback on the process.

The backup process is not documented correctly, or I couldn't follow it. (this is from stock mind you)

Step 1 is to unlock boot loader, that wipes your phone.

There is no way to backup before the boot loader unlocked.
[OnePlus 6T  Guides, News, & Discussion] noobiedev83:
how can I restore a backup because they show you how to run a full backup but how do I restore that backup from adb?
[OnePlus 6T  Guides, News, & Discussion] AnonymousTipster:
Thanks to the new MSMDownload tools (9.0.11), it is now possible to directly convert a T-Mobile 6T from the stock firmware, with LOCKED bootloader, and LOCKED SIM directly to the international firmware! https://xdaforums.com/oneplus-6t/how-to/t-mobile-6t-to-international-t3888307

If you want to unlock bootloader at that point, then it's just a simple fastboot oem unlock WITHOUT having to wait 7 days for OnePlus unlock bin.

I tested it myself.
[OnePlus 6T  Guides, News, & Discussion] gigawatt:
What about unlocking the sim slot, does it also get unlocked by flashing the msm tool or do people with the t-mobile have to unlock with the t-mobile app first? Could someone try to slip a sim after the msm conversion?
[OnePlus 6T  Guides, News, & Discussion] imrock666:
Good question, but I think you need to unlock the phone thru TMobile app or the two simcards will just work with TMobile network or carriers like metro PC's Wich uses the same infrastructure.

This is just my opinion.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
The backup process is for main system partitions such as your nv data, userdata is entirely up to you tbh, there is a method to backup data before wipe, but it is pretty hefty, the backup is placed after bootloader unlock for a reason, just to save your major critical partitions, I do have a script to restore it as well, but that's beyond the scope of this guide, as its a conversion process, NOT a device recovery thread, we have the msmdownloadtool for that, no one should be messing with nv data using this thread, that backup is in case for some weird reason you lost that data, you can restore your imei, etc.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
The backup is only there to restore criticals if yours got corrupted, its a lengthy process, I'd advise restoring using the msmdownloadtool unless you've messed with your criticals and corrupted your nv data or something.

You can restore those partitions using the dd command, some can be flashed via fastboot as well. The corresponding partitions are in the script.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Easy conversion, have fun!
[OnePlus 6T  Guides, News, & Discussion] coolmaster121:
Thanks for the clarification.

I knew I was just confused... sorry for the dumb comment...
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
It wasn’t dumb at all, and I do have scripts to restore those partitions if the need arises, outside of devs messing with partitions, I haven’t seen a need to post them.

I'm a noob with this stuff. When a new update comes, how do we install? I downloaded Oxygen Updater at the recommendation of a post somewhere.
[OnePlus 6T  Guides, News, & Discussion] Addiso:
You will use the local update process. Once a new update comes out you can find it in one of these threads by funkwizard and someone will post the captured OTA. Once download all you will need to do is put the file to the root of your storage head to settings updates and hit local upgrade and you will select the OTA you downloaded. FunkWizard has a process on his thread as well.

100% You can install updates in TWRP. You need to download the FULL OTA zip, flash in TWRP, flash TWRP installer again, reboot TWRP then flash Magisk, reboot and you are on the latest version.

You may want to reread the steps from Dark Nightmare

I don't use Mac so I am not sure I can help you. It doesn't help when you simply said you "Followed everything in the guide" without telling others exactly what you did. Since your phone still boots to T-Mo logo, it appears to me you made the same mistake I did and flashed the TMOUS_OPO6T_9.0_FULL_ROM.ZIP instead of the full fastboot ROM. It's either that or you did something else incorrectly..

This is what I did, using a Windows PC:

I downloaded 9.0.7-OnePlus6TOxygen_34_OTA_013_all_1811270327_fbabbb-FASTBOOT.zip after unlocking the bootloader.

Extracted the zip file into a folder and then unzip the image.zip and Others_flashall.zip files and put those images inside the same folder without any subdir, then used flash-all-partitions-fastboot.bat to flash the fastboot ROM.

After flashing the 9.0.7 ROM I relocked the bootloader and used local upgrade to flash the most current ROM. The 9.0.11 ROM is OnePlus6TOxygen_34_OTA_018_all_1812260723_29c01e73 2b714cfa.zip.

If in doubt, reread the [MENTION=4204048]Dark Nightmare[/MENTION]'s OP. Good luck.

Steps to relock the bootloader:

1) Reboot phone back to Fastboot

2) fastboot oem lock

3) Boot into OS, disable "Enable OEM unlocking"

4) Factory reset again for good measure
[OnePlus 6T  Guides, News, & Discussion] eromore189:
So i just recently decided to try this process. I have extracted the images.zip and Others_flashall.zip and placed them back in the original .zip file for the full rom with no sub-folders. I run the flash-all-partitions-fastboot.bat and it ask if i want to erase my device, so i press yes. But all the .img and .bat files that are suppose to get installed dont and instead of saying completed on the command window, it gives an error and doesnt install anything. Can someone please help out. Thanks.[IMG="Command Window"]https://imgur.com/Q1WxpDA[/IMG]
[OnePlus 6T  Guides, News, & Discussion] guywong:
Don't know if this is the problem. Your picture doesn't show up. Does the folder you flash with the .bat file look like this one, with abl.img at the top, followed by adb.exe?

https://www.flickr.com/photos/guywong/46043902834

When expanding the two .zip files, the default is to put them into an image subdirectory, you need to override that by deleting the subdirectories in the command. E.g., you need to change from the default command from

C:\Users\Guy\Downloads\OnePlus\Unlock6T\9-0-7\images

to

C:\Users\Guy\Downloads\OnePlus\Unlock6T\9-0-7\

This was my screen when I flashed the .bat file:

Extracted Image files and ADB/FASTBOOT Mac tool and the Flass-all.sh for mac.
