Need help getting back on the International version after bricking phone.

Hello Guys, wanted to know if I am out of luck or is there a chance for me with this One plus 6t Phone.

So it goes like this. As it turns out the phones were originally the T-mobile one plus 6t phones that were flashed to the international version which removed the T-mobile Logo and gave it the dual sim option. HOWEVER they were still locked to T-mobile's network. I sent them off to a guy that did some work for me in the past and he somehow got the network unlocked but when I got the phones back The phones once again had the T mobile logo, single sim option.

I decided that this was an easy fix and flashed the phone using the MSM OnePlus 6T MsmDownloadTool v4.0.58 (OOS v9.0.11) provided by iaTa, only to brick the phone! After staying up until 1 AM I figured out how to go back to the Factory Tmobile flash [TOOL] T-Mobile OnePlus 6T MSMDownloadTool [Firmware 9.0.13] [8/9]

This Unbricked the phone and went back to the Tmobile settings with the network still unlocked but obviously has the Tmobile logo and the single sim option. Could anyone please help out and point me to the correct version MSM or a specific set of flashes in the correct order for me to get back up to the International version? Not understanding why it keeps bricking the phone when attempting to install the international version.

Again as of now the phone is on Oxygen OS 9.0.13 with the Tmobile logos and single sim.

Yes I have done just that but for some reason it keeps bricking the phone into boot loop when going up to MsmDownloadTool v4.0.58 (OOS v9.0.11 and Yes I made sure I was on a pre 9.011. Cannot figure out what I am doing wrong :crying:

I used to twrp back up all the partitions on a different phone. for 1+6T, I don't feel the need to root. Is there a thread to talk about full backup partition for unrooted device? adb pull seems just copying files. Thx

EDIT:

I run msm tool in 10.3.0 package and got load profile failed. What should I do?

I was trying to use latest 9 msm tool to convert tmobile ver 10.3.0 into international. The flash seems successful but I still see full-page Tmobile logo for a while during startup. I guess it doesn't succeed, right?

The previous post says every time I use this msm tool it will go back to 9 ver 1. So how can I update?
[OnePlus 6T  Guides, News, & Discussion] fastjohnson:
Will this work on the T mobile conversion. And I see it will relock the bootloader now will require the code to unlock it again after flash. And will it relock the Sim after flash as well because my device was Sim locked when I bought it but I converted it now it's unlocked and the BL is unlocked running a custom ROM. Or will the tool see it as the global version and just fail.
[OnePlus 6T  Guides, News, & Discussion] Anirak:
Thank You

Thank you so much for this. I picked up a 6T 'unlocked' from Amazon. The seller had done the tmobile unlock thing, breaking Google Pay and Netflix and who know what else. Worked like a charm (I did have to install the qualcomm usb drivers to get my phone to show up).

[OnePlus 6T  Guides, News, & Discussion] hyankov:
I am very sorry for my noob question but I am trying to get a clear answer ...

I have OnePlus 6T T-Mobile version that I've bought directly from OnePlus. It runs Android 10. I want it downgraded to Android 9 (for the 'dun' APN). The phone is unlocked, but the bootloader is as it was and I have no desire to mess with it. Is this going to leave my phone branded and with a tmobile locked bootloader?

Can I use the tool from the first page ('ANDROID+9+OOS+9.0.13+fajitat_34_O.13_190725_repack.zip') to downgrade to 9? I think the answer is 'yes', but I had to ask ...

Thanks

Edit: Well, nevermind, TMo screwed the 'dun' sometime Oct 2017, so all of Android 9 is messed up.

what are the differences between these?

MSMDownloadTool 9.0v2: DOWNLOAD LINK

MSMDownloadTool 9.0v1: DOWNLOAD LINK

MSMDownloadTool 9.0.13: DOWNLOAD LINK

is this just flashing a different version of the stock 9.0? ie 9.0.1, 9.0.2, and 9.0.13? I read that the last android 9 from T-mobile is 9.0.16. is there a way to update to that? Only reason I'm looking at this is to fix my horrible 5GHZ disconnect problem after the phone updated itself to android 10. one day i had it charging and it installed updated itself as i was avoiding the 10 update on purpose. After doing this will the phone still try to update to Android 10 again?

Will this fix any A/B slot issues?

Edit: I was vague because I assumed this installed over both of them and was looking for confirmation.

I installed the same version os on both a and b. I got stuck in boot loop and installed in the same is on the other slot and it booted up.
[OnePlus 6T  Guides, News, & Discussion] blushrts:
Not sure what A/B issues you're referring to but the tool is only for loading stock one plus software on a TMobile version of the 6T.

There is another MSM tool thread if you have the non TMobile version of the phone.
[OnePlus 6T  Guides, News, & Discussion] struggleb0x:
I am speaking to the partition slots.

I was asking if the msm tool overwrites both or one.

If it overwrites both, it should fix my problem. But I wanted to ask around before getting stuck in a boot loop.
[OnePlus 6T  Guides, News, & Discussion] blushrts:
I'm pretty sure it rewrites the whole phone so yeah does both slots
[OnePlus 6T  Guides, News, & Discussion] struggleb0x:
Thought I should share that this fixed my A/B partition issues.

A little background into my symptoms.

No emojis. Slate font was italics. If I locked bootloader, device was corrupted. If booted to other slot, boot loops. If I factory reset, personal data remained, and it would fix all my problems until I rebooted, which is why I suspected A/B partition issue. Handful of apps would not function correctly.

I don't use and haven't used or do I want to use windows in many years. Trying to sell my OnePlus 6t and it's converted. There is no other way I guess except this to get my phone back to T-Mobile so that the bootloader warning bs will be gone?? Can I flash a T-Mobile OOS rom when I'm global or will it fail??
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
1. The OTA will work fine, it restores the device to factory.

2. It will wipe your device

3. It will lock the bootloader

4. The device will be the same as the day you bought it software wise.

I tried to answer most of these questions in the FAQ, kindly read the faq first everyone, will save some clutter so future users won't have to comb through full threads for answers, thanks.
[OnePlus 6T  Guides, News, & Discussion] SmileBigNow:
So you saying as long as it's a T-Mobile OP6T not a matter which OX version I am on this tool will work for me?
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
As far as my knowledge goes in regards to the tool, the answer should be yes once your bootloader is unlocked.
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
It will work with your bootloader locked as well. (As well as never running the cust_unlock command either).

This tool can be used for all of those people that will come out years later and talk about how Pie was the last good Android version, how they don't like this, don't like that, and want to go back to the very first version that came out.

Ok cool, my main concern was basically since I am already on 9.0 V2 if the tool will work for that as well, but I guess you answered that it will work not a matter what version the phone is as long it's a T-Mobile device!

I always figured this tool either existed in the ether or the AWS share, but would take forever to leak even without a password.

[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:

[OnePlus 6T  Guides, News, & Discussion] :
Will this tool allow us to wipe everything? Meaning can this phone wipe the criticals? Then all a full flash of international firmware? One of my constituents seem to think if this tool existed at all, it should allow us erase the criticals and then allow us to rewrite them with the intl criticals.. i have no knowledge of this type of program. Sorry if it sounds ignorant or what have u
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
I’m not sure of the tools alternate functions outside of device recovery, maybe someone who knows more can answer your question.
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
No. This is simply a tool created by OnePlus that mimics functionality of Qualcomms QFIL program. Except it is all inclusive. The ops file contains the emmc/ufs flasher and an OEM signed factory rom, partition table, all that fun stuff.

This tool does NOT get rid of the security checks that are in place. The bootloader itself has contradictions from stock bootloader's plus what OP has added.

For example. The "unlock criticals" command. This simply allows the partitions to be flashed. It does not remove the security checks within those partitions. (It also doesn't actually unlock those partitions. It just says it does, but if you attempt to use fastboot flash, it will tell you that the partition can't be written to. Contradiction).

There's security checks in the partitions, there's also no way to "flash" them. It would need to be a rooted raw restore (adb shell dd). And even when you do flash it, the security checks are in place and you'll get a device mismatch.

There's also no real reason to do a full conversation, unless you simply wanted to go stock and get OTA updates and never mod your phone. The biggest thing is the modem. They're interchangeable. TMO has both SIMs enabled. Stock Global ROMs will be flashable hours within being released for global devices.

With all that being said, what exactly is this tool? This tool is nothing more than a recovery. It allows someone to go back to factory stock no matter what kind of mess up they've done to their partitions. The EDL is in the primary bootloader located in the SoC and can't be written to. As opposed to the standard bootloader that we all think of that's located in storage. So this tool makes your device totally safe to any sort of damage you do. It's called a "firehose" in Qualcomms terminology. It gives you full access to the pipe and you blast the whole thing and start fresh.
[OnePlus 6T  Guides, News, & Discussion] :
Great thank u.. to blast this out fresh, i noticed the drivers dont have an executable file.. do i just place in the working directory? And last question do i run msm factoryexe or the regular msm. Exe?
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Go to device manager, choose to install your own drivers and browse to wherever you unzipped the driver files.

Just run the regular msm exe file.
[OnePlus 6T  Guides, News, & Discussion] runningnak3d:
Just a clarification on that point. EDL is not a partition, it is in the CPU ... part of the PBL. But you are correct, no matter what you do, you can't damage or change the PBL or EDL mode.

[OnePlus 6T  Guides, News, & Discussion] :
Thanks guys, i have been testing flashing various op6 system images with our vendor and in doing so i have acquired a nice list of what works and does not. But... I would like to fresh install to avoid any corruption...and i had said before blue spark /data hack works, it does but only img files, ie system, boot, etc. It cant find file path for zips
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
Yes, you're correct. I used partition incorrectly as it's not part of storage or even part of the NAND at all. You can replace your NAND with a blank one and still use this tool. As you said it's part of the PBL located in the SoC.

I've edited this part of my original post. Thanks.

You need to be in the Qualcomm EDL mode before you load the driver.

Power off the device. Press both volume buttons, and while holding those buttons, connect the USB cable that's already connected to your computer. Your screen will be black/blank, but you'll hear the USB connection noise in Windows.

Windows has the drivers already built in. It should auto install. You'll need the drivers if it shows up as an "unknown device".

If it's showing up as a portable device, you're not in the correct mode.

[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
You can make copies of all your partitions using adb pull while booted into twrp, then you can just flash them back. Will be a lot quicker if you're just flashing single partitions. (Which you should actually flash more than just the system partition.)
