Hi everyone, similar to the previous threads for
OP3, OP3T, OP5, OP5T, OP6, OP6T, OP7, OP7PRO, regular OP7T, T-Mobile OP7T, regular OP7TPRO, T-Mobile OP7TPro 5G, regular OP8, T-Mobile OP8, OP8Pro and OP Nord here are the EDL packages (also known as MSM tools or unbrick tools) that can revive a bricked OnePlus 8T.

You should also be able to rollback your phone to a previous release of OOS with them if for some reason you want to go back to an older firmware :)

You can download the following versions:

KB05AA tools (international firmware):
ANDROID 11:


KB05BA tools (european firmware):
ANDROID 11:


KB05DA tools (indian firmware):
ANDROID 11:


Tips:

While crossflashing does not seem to break your /persist unlike on 8-series, it is advised that you back it up before attemting to do so as fingerprint reader may give an error related to enrollment issue. You can do so by using dd if=/mnt/vendor/persist of=/sdcard/persist.img (you must have root access, which is not something I'm going to explain here) and moving it to your computer/cloud.

Instructions:

Launch MsmDownloadTool V4.0.exe.
Windows 7 users may use MsmDownloadTool V4.0_Win7.exe instead, but it hasn't been tested.


On the login prompt select "Other" in the dropdown menu and click on Next.
Wait a few seconds until main window shows up.
Click on Target button and select O2 while using global tool or India while using indian tool or EU when using european tool.
Press Start button (this is done so that device will be "captured" automatically by tool instead of going back to normal boot after 10 seconds)

Power your device off.
Let it cool down for one minute.
Hold both volumes in to get in Qualcomm EDL mode and the screen will stay black. While holding, plug in the USB cable from your phone to your computer. Let volumes go alter plugged in.
Wait some time (should not be longer than ~300 seconds).
Enjoy your brand new device.

FAQ:

Does this work on Mac or on Linux?

Unfortunately no, tool is Windows only. You should need at least Windows 7.

Why is my antivirus freaking out when unzipping the archive or running the tool?

In an effort to protect reverse engineering from being done (and by extension prevent conversion process like it was done on 6T and 7Pro), OnePlus now use VM Protect V3 in their MSM tools. As this tries to detect debug environment, this is seen as malicious behaviour by some antivirus.

My device isn't detected when I click on "Enum" button

Go to device manager and make sure your phone shows up as QDLOADER 9008.
If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsoft.com/Search.aspx?q=qualcomm hs usb 9008 ) and install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you downloaded CAB file.

MSM tool is stuck on "Param pre-processing"

Ensure you're using the Qualcomm drivers linked above.

MSM tool is stuck on "Sahara communication failed"

Unplug your phone, get in fastboot mode, turn off phone, wait 15 secondes and get back in Qualcomm EDL mode. You can also try using a USB 2.0 port instead of a 3.0 one.

What is SMT Download mode?

Just don't try to unlock that mode, it will wipe your IMEI and your Widevine certificate if you use it.

How can I fix "SMT config not found" error?

Will this work for the T-Mobile OnePlus 8T+ or only the unlocked version?
If it does work I guess I'll have to wait for my bootloader unlock code from OnePlus before doing this, or will this bypass it? (I'm already SIM unlocked but Everytime I try to request a Bootloader unlock code and press submit it tells me to enter a valid code, OP claims it's because it's not yet 45 days from when I purchased the device, which doesn't make sense)
#3 I don't see the link anywhere where I can download the MSM tool, it says download tool but does give a link
Thanks for your great work

MSM tools don't care about bootloader lock status. So IF, and that's an IF until we hear otherwise, it works with our model, you won't need to be bootloader unlocked before running it.

I personally won't do anything until we also have the T-Mobile MSM tool as well.

Assuming it works, will I be able to go with the version of the MSM tool from TMO to International OS or I'll need to wait for the TMO MSM tool and load the International OS into that MSM tool and get it done that way?

Not sure. It wasn't possible with the 7T Pro because the device name was different (hotdog vs hotdogg). OP would be better able to answer this.

I'd assume it's the same here as well, because recent years were always that the case and I'll be surprised if it's not the case here as well, so I guess I'll wait a bit longer for the T-Mobile MSM Tool

@SmileBigNow you need to open the spoilers to see the download links
Additionally above files are strictly intended for unlocked units and cannot be used for conversion, however I got the file to unbrick T-Mobile variant as well, but I would prefer if someone could confirm it flash on their device before releasing it, feel free to DM me on here or Telegram (link on my profile). Note that I prefer latter.
If it works I will make a separate thread for it.

Edit 02:52 UTC: T-Mobile MSM tool is now live at https://forum.xda-developers.com/oneplus-8t/how-to/op8t-unbrick-tool-to-restore-device-to-t4180981/

I have the same issue. OnePlus reps couldn't wrap their head around that I'm already network unlocked... Kept saying I needed to wait the 45 days which is complete horseshit. I had my 7t unlocked within a week and bootloader unlocked in 2. I get the same invalid unlock code error. Good God. They even tried to tell me "the unlock code TMO gave you is bad..." Like dude...I got the **** FROM THE PHONE ?*♂️

So did you attempt to use the MSM tool w/o unlocking the bootloader?

Yeah, it doesn't even make any sense the 45 days wait, the 45 days is usually to get a SIM unlock from T-Mobile not a unlock code from OP, they are just coming up with stupid excuses

Exactly... The OnePlus reps are getting especially ****ing retarded right now. You think they'd know the process well enough to know that if we are SIM unlocked we don't need to wait the 45

    Finally, I just got the MSM Tool mentioned in that post and was able to get my phone back to H2OS!

    Here is the link for those who don't have a OnePlus account or Baidu account:
    (Note that this is for H2OS 11.0.7.12.KB05, not OxygenOS.)

    Hope this helps someone out there.

    I have also noticed few tips when using MSM Tools:
    - If you get a "packed image not exist" error, make sure that your downloaded path does not contain multi-byte characters
    - If downloading image to the phone fails in progress, you can try again by checking the "Use Firehose Lite" option (to use little slower and safer protocol)

    It can be picky... Took me several tries to get the timing / combo right.

    The MSM tool only recognized the device briefly so I needed to be quick with starting the process.


    Can you explain a little more in detail as to how?
    Thanks


    UPDATE......
    Holy Cows Baby. It's working!!!! Hope this works. Took your advice and tried different combo's and it did it.
    Downloading now. Thanks!!!

    That's good. I didn't think that would restore cyberpunk also.

    @Some_Random_Username You can add this as a MSM tool for Chinese model KB05/Cyberpunk https://androidfilehost.com/?fid=10763459528675590014
    @g96818 sorry but I intend to keep this thread dedicated to OxygenOS MSMs. You or anyone else is free to create a thread for H2OS MSMs, if it hasn't already been done.

    i follow these steps then i succesfully boot into fastmode
    And i key these two commands:
    "fastboot flash boot boot.img"&" fastboot flash recovery recovery.img"
    Above two imgs were succesfully boot too.

    However,when i press the power button of my phone to START.
    it shows CrashDump again...

    My ROM version is 11.0.6.8 Indian,and i cant use MSM tools too

    Did i do something wrong in these steps
    Or i have nothing to do but Hope the new MSM vesion would comin soon:sleep:

    If you don't mind losing all your data on the phone. Just use any of the available Indian MSM tools in this thread to restore your phone and downgrade. Then update to latest OTA.
