Appreciate your info. I'm a Linux guru and haven't used windows in many many years and don't like to. ? I reinstalled Qualcomm USB drivers rebooted PC and ended up using the same exact conversion with the TMobile msm 9.11 tool and the patched file from the conversion thread just like I'd originally done when I initially converted my device from TMO -to-international model. The international tool would not work but doing the reconvertion did the trick. If anyone else is in same boat.. I was on 10.3.4 and installed the OOS from Omni roms op and then I installed twrp recovery installer and when I rebooted recovery It took me to the screen with yellow letters saying "hardware doesn't match baseband." So if this happens to you and you too have a TMobile 6t just do the TMobile to international conversation again and run the patched tool and you'll be good. That's what I did and then I just unlocked bootloader again (fastboot eom unlock) and flashed 10.3.4 OOS on both slots and I'm back on a rom again now thank God. This tool is a life-saver!! Much thanks op and all who help. Im attaching some pics of the error I had that I was able to fix with installing the Qualcomm USB drivers again thanks to the user above me who commented and also the op for the tool and other conversion thread for patched tool. ?

originally i got the qualcomm crashdump error. i've tried all versions. they all said download completed but the phone boots back to the same qualcomm crashdump screen.

any idea?

thanks
[OnePlus 6T  Guides, News, & Discussion] lollyjay:
I need help. I handed my phone to a friend. He pushed buttons (he says power and both volume up and down. Now the phone is dead. Nothing on the screen and doesn't show up when connected to the pc.

Any suggestions?
[OnePlus 6T  Guides, News, & Discussion] onliner:
That's EDL mode, disconnect the phone and press power+vol up until the phone reboots (like 30-40 seconds).
[OnePlus 6T  Guides, News, & Discussion] lollyjay:
Thank you so much for your help. I had totally forgotten about EDL mode:silly:
[OnePlus 6T  Guides, News, & Discussion] flash713:
If it happens again hold both volume buttons down and your power bottom until your device boots to fastboot mode. Soon as you see your screen say "fastboot" release all buttons. Then you can select power button once so that your device will reboot. Should read "start" on your phone screen. Just tap power once and your phone should reboot system. I have not gotten crashdump error on this but I have gotten it a few times while using a custom rom and doing what I explained here worked for me. I didn't ever see the crash dump error again ...
[OnePlus 6T  Guides, News, & Discussion] TheRandis:
uhh ohh.

well, my install failed 500+ seconds in. i think my phone is bricked.

Downloading vendor.
[OnePlus 6T  Guides, News, & Discussion] flash713:
You are converting T-Mobile 6t to international? If so make sure you are clicking on the patched tool and you are more than likely not bricked. Just look and see if you still are connected via device manager ... If so sound's like you have a driver issue. Try uninstalling Qualcomm USB drivers then reinstall them and reboot and run patched tool again after you make sure your device is connected via device manager.

Edit
[OnePlus 6T  Guides, News, & Discussion] TheRandis:
So I uninstalled and re installed drivers a rebooted. I am now seeing my phone connected in the Patched utility. Now it is failing at the 16s mark. Will have to look for posts about Sahara communication.

Thanks.
[OnePlus 6T  Guides, News, & Discussion] flash713:
I believe that's your connection. Try switching USB cables and ports and see what happens .
[OnePlus 6T  Guides, News, & Discussion] TheRandis:
Was able to find my original OP6T cable and it worked like a charm!

Thanks for your help.

Next issue.

I went to the OnePlus website and downloaded the latest update and it says update failed. Is there another post I should look at for help with this?
[OnePlus 6T  Guides, News, & Discussion] pjadec:
What version do you have in your phone

If your phone have version 9.0.13 then update -> 9.0.17 then newest version -> 10.3.4 or newer 10.3.5 which is not yet available

You can check updates with app https://play.google.com/store/apps/details?id=com.arjanvlek.oxygenupdater&hl=en
[OnePlus 6T  Guides, News, & Discussion] TheRandis:
Sorry for delayed response. That app worked like a charm! It even gave me the availability to download 10.3.5 before my phone could find it!

Op8 Unlock Bootloader Flash International - theory

I think what he meant was, is there a patched flasher tool MsmDownloadTool V4.0_patched.exe like on this device that ignores your T-mobile sim-unlock and bootloader unlock status made yet for the Op8 from T-mobile. To be used with flashing the international edition (which just allows fastboot oem unlock with no codes). The current version of MsmDownloadTool.exe V4.0 is 5.1.32.0 and the factory version won't work on TMO.
[OnePlus 6T  Guides, News, & Discussion] sonironak88:
I am also facing the same problem. I am getting the error "Sahara communication failed". I think it is because of my bootloader is locked this is what I got to know from below comments. Is there any way I can unlock bootloader.

My oneplus 6 is totally dead and only hear sound when connected to laptop and when I hold Power + vol up for 10 sec.

Do you have solution for it?
[OnePlus 6T  Guides, News, & Discussion] rmendez011:
This Happened in February, and since then, I have noticed that along with the phone resetting to dutch whenever I reset the phone, I also have the India Exclusive Red Cable Club, and the all the India exclusive stuff like Oneplus India news regarding India exclusive phones such as the Oneplus Nord, the 50% off a new battery replacement, and 50GB of cloud storage. There's an issue with this, I live in the United States, always have, I bought this device off the United States website, so I don't know why the MSM Tool did this to my phone. Is there any way how to convert it back to the United States, English default, Oneplus 6T Mclaren Edition?
[OnePlus 6T  Guides, News, & Discussion] lilbrat:

[OnePlus 6T  Guides, News, & Discussion] FreshlyBaked 420:

This is a Windows tool. What are my options if I'm on Linux? Are there any? Or do I need to find a Windows machine?
[OnePlus 6T  Guides, News, & Discussion] athulda:
I think you might need to find a windows machine to use the tool as this is only available in windows, atleast not that I'm aware of

You could manually flash the stock rom if fastboot option is available in your phone.

Hi Mates,

I tried it, on my Op6t Mclaren edition its just keeps on flashing and repeating again.

my device is not booting Up nor going to recovery or even fastboot.

can anyone please guide any further?
[OnePlus 6T  Guides, News, & Discussion] athulda:
Your device is not booting because twrp is kept flashing the zip file ?

It's adviceble to brief the steps you have done so that we could get a clear picture of your current issue.
[OnePlus 6T  Guides, News, & Discussion] Yashnair25:
So here's the complete story, my phone is rooted since i wanted to use some PUBG hacks, and while gaming it just got into reboot then went to crash dump mode.

I followed the steps given in the thread and it MSM tool shows that flashing was successful but then again it starts to flash again and again and the cycle goes on but my OP6t doesn't boot up.

Anyone faced this scenario before?
[OnePlus 6T  Guides, News, & Discussion] Agrezion:

I am trying to get back to t-mobile rom from international rom. when I connect the device, it shows up as Qualcomm HS-USB QDLoader 9008 (COM4) when I run the MSMDownloadtool , it just sits View attachment 5155645waiting for the device. If I disconnect from the computer I cannot power it on. It shows up in the device manager now without pressing both the volume buttons. what's wrong? Any help is greatly appreciated.
[OnePlus 6T  Guides, News, & Discussion] spyla:
Happy to inform you that I was able to finish the conversion. I had to hold both volume buttons and power button for more than 10 seconds. It powered up. I shut it down and tried it again, this time it worked fine.
[OnePlus 6T  Guides, News, & Discussion] PeaNug:
Any Ideas why the program would give me an error of "param preload" "Device not match image". I checked the drivers and they are correct. I am a op6t on android 10 10.3.5. I also run the program as administrator.

Any help would be appreciated. I purchased this phone to try e.foundation and I didn't realize it was the T-mobile version when I purchased it.

I am on windows 10 also.
[OnePlus 6T  Guides, News, & Discussion] flash713:
What does device manager recognize your device as?? Be sure youre clicking on and running the patched tool if you are converting. This thread has all the info needed and the new search on xda is imo MUCH better than the old one was.
[OnePlus 6T  Guides, News, & Discussion] PeaNug:
The driver says QUALCOMM ..... On that download I did not find anything saying patch tool. I did get the program to work but unfortunately it did not switch me from t-mobile to int version. I am assuming it was just a unbrick program.

To get it to work I updated the phone from 10.3.5 to 10.3.7 and got fajitat_34_O.01_201124.ops to work.

https://androidfilehost.com/?w=files&flid=297704

Is there a patch / int version of this?

I have not been able to find any other files that would work for what I am trying to go.

Well, with tears nearly running down my face I came across this thread and this MAGIC POST!

In particular item 6) which WORKED!!. I had a phone which would not boot, only go between Fastboot and Nothing, not even Recovery. I am a Linux user, and have used LineageOS for many years; even adb would not talk to the flipping phone.

I managed to find a Windoze computer and item 6) "the last resort" worked.

I am VERY Grateful.

Cheers to all in the same boat.

Hi all,

trying to recover my op6t a6013 dual sim, tried several different msmdownload tool versions. I get stuck at 4seconds with 'Recording download time' or other times 'Images do not match with the phone!.' Tried disabling digital signature verification and reinstalled qualcomm driver.

[OnePlus 6T  Guides, News, & Discussion] 3MrBojangles3:
yes that is what he meant. I want that too. Cant find a way to unlock my bootloader as ive only had my 8t for a week
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
We actually haven't had any bricks yet. Just improper flashing. There was one, but he swapped his out before any real troubleshooting happened. The rest have been able to recover just fine.

I flashed the criticals to slot b, but never switched my default slot from a. So there was a bit of a mismatch when I was running that way.

As far as I know, we've all been a bit too timid to just dd all of the criticals.

Right now when using the msm tool it gives an error of image does not match device.

Can you take a look at abl? That's the one I'm most scared about flashing.
[OnePlus 6T  Guides, News, & Discussion] :
I even relocked my bootloader and fastboot oem unlock_critical still can't access criticals
[OnePlus 6T  Guides, News, & Discussion] LLStarks:
Why would the phone care once all of the criticals are flashed? There's no typical check like you'd see with a phone that relies on Odin.

Will any of your PBL research apply to the OP6T?
[OnePlus 6T  Guides, News, & Discussion] strictlyphat:
Do u recommend going back to full stock TMobile rom.

My worry is that if an update comes out I'll be stuck on a hybrid ROM with nowhere to go.
[OnePlus 6T  Guides, News, & Discussion] runningnak3d:
Please read this for a good overview.

The quick and dirty is that the CPU has a hash of the root certificate that was used to sign the xbl, and each piece verifies the next piece in the chain.

You can't modify or flash firmware signed with a different cert.

-- Brian
[OnePlus 6T  Guides, News, & Discussion] amg83:
Be a lot easier to make progress if TMO would provide stock rom.
[OnePlus 6T  Guides, News, & Discussion] runningnak3d:
Yes I would.

Google mandated that any phone that was released with Android 9 (Pie) had to implement AVB (Android Verified Boot) 2.0 so that boot and system could be checked for ARB as well.

Now I don't own a phone that shipped with Pie, so I can only go by what I have read on this subject -- that means I have no idea if "unlocked bootloader" means that boot and system won't be checked for ARB. If they ARE still checked, and you end up flashing an international version (boot / system) that has had ARB incremented, you are probably going to end up with a brick.

Again, I could be wrong, and you could be fine. I will be tearing this firmware apart over the next couple of days, and if I find something, I will let you know.

The bottom line is this tool that allows any OP6t *except* the TMO version to recover from a brick is signed with the international cert -- which is why you can't use it on the TMO version. So, unless TMO releases their own tool (which they haven't for ANY other phone) to recover from 9008 mode -- IMHO it isn't worth the risk.

In the "good ol' days" you were at least safe flashing system images. If your phone didn't boot, you could just boot to TWRP and recover. Now, with the release of Pie. Google, the carriers, OEMs, etc can brick your phone just by flashing a system image.

-- Brian
[OnePlus 6T  Guides, News, & Discussion] strictlyphat:
Oooff. You're a beast. Lol

So we fastboot flashed to get to 9.0.5. I can just fastboot flash back right?
[OnePlus 6T  Guides, News, & Discussion] runningnak3d:
Yes, if you made a backup.

However, I just took a look at the system image, and it is RSA signed. Since an unlocked bootloader ignores that RSA signature, that also means that ARB would be ignored since they use OU 1 for the ARB version.

So, it looks like you are safe flashing non-critical partitions as long as your bootloader is unlocked.

I can't say this enough though -- if you force flash a critical partition (either with fastboot or TWRP or dd), you will be stuck in a bootloop that you can't fix.

-- Brian
[OnePlus 6T  Guides, News, & Discussion] strictlyphat:
Awesome. We have a fastboot flash able way to get back to stock in another thread. I'll keep to fastboot flashing the updates as they come. The intl firmware.is worth the hassle lol
[OnePlus 6T  Guides, News, & Discussion] ozzmanj1:
That is what I plan to do, unless something comes along and we are forced to go back to Tmo software.... bleh.

Runningn4ked

How likely are we to run into issues down the road flashing on the needed system partitions with updates?
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Unless there's a major update, which will bring a bootloader update such as 9.0.5 to like 9.1, etc, which we'll probably get from t-mobile, so that would require a flash back to t-mobile, and then we can proceed with the usual fastboot flashing, that's if the bootloader/critical updates breaks something in the firmware itself.
[OnePlus 6T  Guides, News, & Discussion] Velrix:
You get a device that says there is a hardware/software mismatch just like when the user took the OTA from 9.0.4 to 9.0.5. I did it for testing, you can however get into QUSB mode which this tool should fix yea?
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Not for t-mobile users, it does a sig/hardware check as the OTA did.
[OnePlus 6T  Guides, News, & Discussion] Velrix:
​

No the OTA didn't check anything it just flashed it. Same if you do it via script.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
It was a hardware mismatch error....
[OnePlus 6T  Guides, News, & Discussion] runningnak3d:
The OTA is for your device. If someone saved the OTA for the international version, and you flashed it, it skipped the critical partitions.

If you are in QDLOADER mode, you have a brick.

Your problem with the msm tool was that you were putting it into fastboot mode and running it. That is your problem. In order to use the msm you need to put the phone in EDL mode. Emergency Download I think it stands for. And you get it there by unplugging your phone, turning your phone off, and then by holding both volume buttons firmly and plugging in your cable while still holding the volume buttons down. That puts it into EDL mode. The screen doesnt come on. If it does then repeat the steps. You can hold the volume buttons down until you start the msm tool otherwise you only have like 10 seconds to start the tool before your phone powers up. If your phone ever won't turn on then hold down the power button and the volume up button and it will boot up. Takes 5-10 seconds
