Well that certainly clears thing up for me. It's been about three years since I last rooted a device(after 6P, went to a few Huawei devices and then to LG), with all the locking down of devices and not being able to find any loophole, I got out of the game for a while. I have a good bit to catch up on, so I do appreciate your time to explain some things and all your efforts to keep things going for us and this device. Fingers crossed you can find a solution. I wish I had more knowledge to assist you and the efforts of all working to bettering this variant. It's a shame that TMO went this route and kept the end user from have the full experience of the device. I am glad I flashed to the international as well, what a differance in the overall experience.
[OnePlus 6T  Guides, News, & Discussion] Addiso:
Don't think your bootloader changed, you can relock/unlock your bootloader anytime you want without the bin file after flashing the cust_unlock the first time.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Not true, all previous bootloader locking/relocking/unlocking has required the bin file.

Also something clearly changed, I’m unable to go back to full stock using the download tool, getting the new tool, hopefully it works.
[OnePlus 6T  Guides, News, & Discussion] jimlightner:
Not necessarily you could always call T-Mobile and beg the crap out of them to sim unlock you.keep calling until thay do it..
[OnePlus 6T  Guides, News, & Discussion] Addiso:
I see thanks for the info! I stand corrected.
[OnePlus 6T  Guides, News, & Discussion] TKruzze:
Was finally going to take the plunge and unlock my TMO 6T tonight and flash 9.0.7 via the 2 step update... Fingers are crossed that the new tool works for you.

For clarification, I'm assuming the 'new' tool you're referring to is the TMO version 2, right?
[OnePlus 6T  Guides, News, & Discussion] moist_line:
Thanks Dark Nightmare, I'm on 7 through local upgrade. Is it safe to follow any guide at this point to install magisk and twrp?
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Correct, that didn’t work either, so I’m a little concerned about recovery now for possible bricks.

Root is the same no matter what firmware you’re on, so go ahead.
[OnePlus 6T  Guides, News, & Discussion] TKruzze:
Yikes! The next OTA could leave you in 'No Man's Land' with no way out...

I think I'll wait a bit to unlock and flash. With no way to currently return to stock and no idea what the future might bring this doesn't seem the way to go at the moment.

That said, I'm fairly certain something will develop soon to fix this issue.

PS: I'm guessing you tried the Int'l MSM Tool? At least to rule out that it's a pathway back?
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
First thing I tried actually, lol. Well if you don't relock your bootloader or you don't mind wiping, we can always update using the fastboot method, I currently have a power issue, I'm going to attempt to flash 9.0.7 via fastboot, see if that resolves the issue, maybe stick to fastboot updates going forward, maybe not since clearly some criticals were updated, therefore I may actually be fine for local updates, just not for OTA's, not sure about OTA's yet and I can't test since it won't let me dowgrade to 9.0.4 and I can't convert back to t-mobile firmware, so can't revert to try that way either, lol, this was fun at least.
[OnePlus 6T  Guides, News, & Discussion] TKruzze:
Good luck! Anyways, thanks for placing your 6T on the proverbial altar to at least discover for all of us how far we can push things with our TMO devices.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Resolved, usb port was faulty, hence after pushing the first half of the data, it caused write errors, etc, I will proceed to convert to 9.0.4, local upgrade to 9.0.5/6, then proceed to test OTA update to 9.0.7, report back when I'm done.

Phew, that was fun lol.

Update 1: back to stock t-mobile v2.

Update2: on 9.0.4, locally upgrading now to 9.0.5

Update2: Aaaand hardware mismatch, I did update from 9.0.5 to 9.0.7 locally, so, like I said, something changed in the 9.0.7 update, so advisable to approach updates with caution, should they change things back again, I'll gladly test when new releases come, since idc about wiping my device constantly, lol.
[OnePlus 6T  Guides, News, & Discussion] Nileshdd:
You tried to go from .5 to .7 by using the OTA method right? And that caused the mismatch? Does that mean .8, when it arrives, will most likely not work using OTA? We may still have to use fastboot or local update?
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
No, I went from .4 to .5 and it had a mismatch, I went from .5 to .7 perfectly fine, if I were to make a guess, I'd say the .7 full rom skipped checking something or the other, but it did change the bootloader, since it no longer requires the bin file to lock/unlock the bootloader at the moment.
[OnePlus 6T  Guides, News, & Discussion] Nileshdd:
Ah ok. Looks like only .7 allows for local update. We will have to wait for .8 then to see if OTA works. No need to use fastboot or local upgrade then.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
We'll see, have to wait it out and see, if you've got nothing to lose, go for it, if not, let others test... I'm still on the fence about this though.
[OnePlus 6T  Guides, News, & Discussion] strictlyphat:
No u can't
[OnePlus 6T  Guides, News, & Discussion] Addiso:
I knew I wasn't tripping when I didn't need the bin file when I relocked and unlocked on .7, learning new things about OnePlus everyday. There has to be once certain partition that causes the panic. We need to compare partition that are on .5 and .7. Maybe certain critical can be flashed? Who knows I'd love to dig deeper in this but not the right guy for reading partitions.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
See the thing is, there was attempts to swap criticals before and it caused a mismatch, so I'm thinking, maybe OP devs are giving us a break? Flashing the bootloader then was a no go, now it's suddenly fine... now I think of it, this may actually open the door to new possibilities.
[OnePlus 6T  Guides, News, & Discussion] AnonymousTipster:
Yes, that revelation was why I started this topic in the first place: https://xdaforums.com/oneplus-6t/how-to/t-mobile-6t-to-international-t3876701

I gave you and [MENTION=9281546]Alec_Lightwood[/MENTION] credit for getting this whole thing kick-started. Without you guys we wouldn't be where we are with the 6T.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
I'm still on the fence about future updates, I happen to be comparing the files right now and the bootloader in the .7 update was very minimal, as suspected compared to previous bootloaders, which caused mismatches, so this is definitely a plus, but it makes future updates seem somewhat risky should they put a full bootloader image like they used it or go through the normal rsa checks... I'm just concerned about the number of users having to wipe/unlock and fastboot update/restore from a softbrick due to future updates... as reflected by my warning when discussing the local upgrade steps.

edit: On the plus side, if anyone is good at hex editing the ops file, can you send me a PM please? I have a theory I'd like to test.
[OnePlus 6T  Guides, News, & Discussion] strictlyphat:
Don't worry. U ahve done so much for us so far. When next.ota comes I'm gonna be the first to test.
[OnePlus 6T  Guides, News, & Discussion] Flyinace2000:
Can we update to Magisk v18 or just leave it on 17.3 ?
[OnePlus 6T  Guides, News, & Discussion] moist_line:
I'm on 18 and it works fine, at least as far as I know. Perhaps others could chime in too :)
[OnePlus 6T  Guides, News, & Discussion] SourPower:
You can update directly from the app
[OnePlus 6T  Guides, News, & Discussion] tengtengvn:
I've been using v18. No issue found.
[OnePlus 6T  Guides, News, & Discussion] free4flight:
On v.18 ...no issues.
[OnePlus 6T  Guides, News, & Discussion] :
Pretty sure the last full rom ota zip allowed the flashing of criticals. We still cannot flash them ourselves so they're still locked down..for now. But I did a dump and compared. The sizes are different now. I'm talking about, xbl, hyp,rpm, ..the criticals. I'm thinking and will try it later, my theory is the intl tool will work now. Then it would be unlocked from a critical partition standpoint. Cuz if it runs the checks it will show correctly.. if not we wait for their tool to be updated to 9.07. cuz I can't dd anything without the mismatch still. But as we can see they are indeed flashed. We are on to something. Best case scenario, OnePlus made a decision to make a more unified update to help those of us unlocked with t mobile locked ish devices
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
We still can’t use the global msmdownloadtool, I tested this a few pages back, and from what I’ve noticed, the criticals had minor changes, so just minor additions were done to the existing files, therefore if they make a full critical partition change or full flash, they may lead to a mismatch again, hopefully I’m wrong and we can keep doing full rom flashes going forward, even if we can’t take OTA zips, or maybe those will work now too, we’ll see.
[OnePlus 6T  Guides, News, & Discussion] Flyinace2000:
Found an issue if you rely on intune root hide (MS O365)

Direct install any magisk updates, every time. Don't do that install to opposite slot crap. U just create more work and potential for issues.dont even have to reflash TWRP or anything.

Any one running into charging issues? A friend of mine had an issue when when the phone is off and then plugged in, the bootloader warning pops up and just freezes there. Holding the buttons restarts the phone, but that still doesn't seem normal.

Factory reset. Or reflash stock. Be careful what mods they install
[OnePlus 6T  Guides, News, & Discussion] B4oE:
After converting the T-Mobile variant into the unlocked version, does that mean that we will now be able to receive OTA updates through OnePlus?

tmobile lock bootloader

I tried to lock the bootloader after flashing the stock op rom and bricked my phone for a sec couldnt boot it just stayed in fastboot

reflashed the stock rom and its good now im just wondering how to re lock the bootloader and if i was doing anything wrong?
[OnePlus 6T  Guides, News, & Discussion] KOLIOSIS:
Welcome to XDA-DEVELOPERS tripp777hello ! :good:

You can re-lock the bootloader by using this tool (use v2,done so myself several times):

https://xdaforums.com/oneplus-6t/how-to/tool-t-mobile-oneplus-6t-msmdownloadtool-t3868916

This does wipe everything & restores it to out-of-the-box condition,totally stock with the bootloader locked.

The 1st boot takes a while,as does the restore,but,this tool is awesome,I've yet to read a post to where this tool does not work.
[OnePlus 6T  Guides, News, & Discussion] tripp777hello:
i understand that but i flashed the stock op rom for a reason and dont want to go back to the tmobile rom so if you or any one knows how to safely lock the bootloader with out bricking my phone again that would be helpfull ps my phone is on stock op rom not bricked anymore just want to re-lock th bootloader
[OnePlus 6T  Guides, News, & Discussion] KOLIOSIS:
My mistake, I misunderstood what you wanted.

There's a way to lock the bootloader after converting the phone from a T-Mobile to the Unlocked version.

Flash any stock firmware below 9.0.7 then, upgrade to 9.0.7 locally & proceed to lock the bootloader.

There's talk discussing it, possibly in this thread here.

But, if I were you, I'd wait, there's still some uncertainty surrounding doing this & taking future updates.

Give this thread a read, it discusses how to lock the bootloader on 9.0.7:

https://xdaforums.com/oneplus-6t/how-to/t-mobile-6t-to-international-t3876701
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
To lock the bootloader, flash 9.0.6 then follow the local upgrade procedure, once the local upgrade is complete, reboot to fastboot and lock the bootloader.
[OnePlus 6T  Guides, News, & Discussion] tripp777hello:
Actually Im on 9.0.7 and did the local upgrade to 9.0.7 while on 9.0.7 and have successfully locked my bootloader it worked flawlessly thank you everybody for helping you have been a great help and source of information
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Great, good info.
[OnePlus 6T  Guides, News, & Discussion] :
Yeah I did mine that way as well. And u can have root with a locked bootloader as well. Prepatch the kernel with magisk beforehand. And flash through fastboot before locking
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
No longer throws an error? ? threw an error when I attempted this last.
[OnePlus 6T  Guides, News, & Discussion] :
I will try it myself, I haven't with this phone yet. I figured the methodology would stand to reason. Does twrp stick with the BL locked? If so maybe full system SuperSU would fly.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Last test neither, the phone wouldn't boot with a modded boot or custom recovery, only modded boot that sticks to date would be aging... but that's beyond the scope of this thread.

Has anyone figured out how to get Google Pay working without rooting/hiding root ? I am not rooted but even then I cannot actually pay in stores on OOS 9.0.7.
[OnePlus 6T  Guides, News, & Discussion] BIGWORM:
I believe the only way is to fastboot flash 9.0.6, local upgrade to 9.0.7, then relock bootloader. Google Pay with Magisk Hide works fine.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
If you're on 9.0.7 already, you can do the local upgrade still and then lock the bootloader.
[OnePlus 6T  Guides, News, & Discussion] BIGWORM:
Did anyone look into the ability to relock the bootloader and stay rooted after a local upgrade?

I used that .bat but it does not change anything in my phone

You can use this tool to go back to stock, but it will relock bootloader. Just have to unlock it again in fastboot. It will also wipe everything. https://xdaforums.com/oneplus-6t/how-to/tool-t-mobile-oneplus-6t-msmdownloadtool-t3868916/

I think this is a known issue. I have the same issue as well. For now I just unplug the phone when turning it on

Update: apparently it's a known Magisk issue.
[OnePlus 6T  Guides, News, & Discussion] deepu458:
actually its an issue with 17.2 i guess. When i used my Essential Ph1 and updated to magisk 17.3 the issue was fixed. But in this Phone case its still happening to me as well the other day where i had my device powered off and connected to charger. So it powered off for a sec and then the boot warning screen popped up and stuck there even after taking the power cable out.

Some how after pressing the buttons combo it came of that state and for a while thought i hard bricked it as it was just stuck at that warning screen with no way of interaction from computer.

Edit. I stand corrected. My bad. I jus did it. I thought it wouldnt, but it does.thanks, dark

How exactly do i do a full backup? TWRP shows up on my device once i run the backup.bat script, i didnt touch anything and i got an error in powershell saying backup was paused because of connection or something.

---------- Post added at 02:46 AM ---------- Previous post was at 02:19 AM ----------

So, which full ROM is safe to flash? Just 9.0.5 from the AFH link in original post right now?
[OnePlus 6T  Guides, News, & Discussion] matistight:
I think so. Because other than the rom, that's the only root thing he had on the phone. Honestly don't know why people charge with the phone off, so I am not surprised that it's a bug. Now he wants to remove the Bootloader warning code....oh boy
[OnePlus 6T  Guides, News, & Discussion] Josh McGrath:
Allow modifications in TWRP.

You can do either adb backup or within TWRP (afik unless it's broken or something)
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Swipe to allow mods, the script pulls the files to your pc folder, you can convert to any of the current fastboot images, if you’d like to lock your boot loader after, then proceeed to local upgrade to 9.0.7 only after installing any of the current global rooms via fastboot firmware files.
[OnePlus 6T  Guides, News, & Discussion] Coderedpl:
But in essence Everytime OP releases an update we can flash it manually after performing these procedures right ?

Just upgraded to the 6t open beta found here https://xdaforums.com/oneplus-6t/development/beta-one-plus-6t-beta-1-t3881071. Did it through local upgrade and did full wipe since its a beta and worked fine. Came from 9.0.7. and previous had tmobile variant converted to international by the script here. Did not test dirty flash and have not tested 9.0.10 which is different from this open beta.

UPDATE: newest beta and 9.0.10 breaks twrp decrypting so i had to adb sideload magisk 18. Went fine and now i am rooted on the latest open beta on the tmobile variant.

I usually just disable mine. There are some modules that require a full uninstall depending on what it modifies though. I'd recommend uninstalling though, or even unrooting through the magisk all as a whole if you're not familiar with what modules cause what. last we want is anyone ending up in a bootloop and panicking after flashing a OTA.

Don't have time to tool around with my phone right now, but I went local upgrade from 9.07 to 9.10 last night successfully. Then Rebooted fine, pinned in, and open magisk, there was an update so I installed locally, the Recommended one. Then my phone turned off like it was going to reboot and nothing. Black screen, I've tried all button combinations. When I plug my phone in the computer it doesn't make any noise like it recognizes anythinig is there, and nothing is showing up in device manager, or MSMtool. I have errands to run today, so I guess I'll try to mess with it when I get home later.
