    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 and OP8Pro here is the EDL package (also known as MSM tool or unbrick tool) that can revive a bricked OnePlus 8 bought from T-Mobile.

    It will only work with T-Mobile variant IN2017

    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:


    ANDROID 10:

    OOS 10.5.7
    OOS 10.5.20: Gdrive - AFH (credits to @rzracer2 )
    OOS 10.5.21 (credits @LLStarks for finding it)
    OOS 10.5.22 (credits @LLStarks for finding it)


    ANDROID 11:


    Mirror for first and last MSMs: https://onepluscommunityserver.com/


    Instructions:

    Launch MsmDownloadTool V4.0.exe.

    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 TMO.
    Press Start button so that it waits for your device to be connected
    Power off your device
    Maintain volume up and down buttons to get into Qualcomm EDL mode.
    Plug your device to your computer.
    Should you not manage to do that and have adb access, you can use adb reboot edl instead
    Wait ~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

    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.microsof...updateid=8ee52ba0-bdef-4009-88cf-335a678dd67a ) 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.

    If you can't get into EDL mode by hardware keys, you may use adb reboot edl (will require your phone to still have ADB access)

    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?

    I'm still having trouble booting to EDL, I've tried the volume buttons, adb command, and fastboot command, but none have worked for me. When trying the volume buttons it just brings me back to fastboot mode. I don't know what else to do.
    Ah yes. I had an "issue" there as well. I'll elaborate and try to make it easy.
    1. launch your msm tool and connect ONLY the end of the usb that plugs into your PC
    2. Power off your phone all the way.
    3. While holding down both the volume up and down keys (I use my right hand for the volume buttons), I use my left hand and plug the phone into the usb cable.
    4. MSM tool "should" say connected after your computer gives you that "ding dong" windows sound.
    5. Click on connect and click start. DO NOT TOUCH THE PHONE UNTIL IT REBOOTS ITSELF. (caps for emphasis)
    6. for good measure, I reboot the phone back into recovery and wipe all sections, meaning these 3 sections: system setting, cache, and pictures, music, etc. I wipe all three sections 3 times to delete and wipe all old stuff so that you phone boots up clean.
    7. Let me know how it goes. Yes, lots of info here but I want to give you a clean write-up and nothing half-assed. It's just the way I work. <thumbs up>

    is yours TMobile edition?

    Yes, it's the T-Mobile version.

    These are files I have in my system to "unbrick:" my device:
    1. OnePlus 8 T-Mobile 10.5.7 -- unzipped the file before you proceed (you all knew that)
    2. QUD.WIN.1.1+Installer-10037.3+Setup -- this is required. If need this, copy and paste this in google. These drivers were hard to find at first. Unzip the download.

    3. OnePlus_USB_Drivers_Setup -- I thought these drivers were unnecessary but they are VERY necessary. (caps for emphasis)
    4. When you have unzipped the QUD.WIN.1.1+Installer-10037.3+Setup file and the OnePlus_USB_Drivers_Setup, go through the setup wizard. NOTE: Oneplus will ask you for something like "Wincom" for something of that nature, click next. It threw me as well. When the drivers have all been setup up and installed, perform a reboot to refresh Windows (it's good practice especially when dealing with drivers.

    Guys who are having trouble: This is what I did. I powered off the phone completely. Launch the msm download 4.0. When the dialog box comes up, get your phone ready. When the phone is completely off, press and keep the volume up and down button pressed. Plug the small part of usb into the phone. While holding the volume up and down buttons and phone steady, I plugged in the fat end into the other usb port on your computer since we're dealing with unbricking our phone. You will know when connection is made when you hear the windows "attached" sound and you will see a "connected" text in the field on the top in the msm download tool launch box. Click on the connected to highlight this and click start. Do not play with your phone during this time. Let the program do its thing and your phone will automatically reboot when done.

    I hope this helps guys. Wordy yes but it beats being confused as hell....

    I have a T-Mobile OnePlus 8. I let my ex-girlfriend use it and she put a fingerprint on the phone. When I start the phone up, obviously it asks me for her password to get into the phone (not to start Android) if I use this tool is it going to completely reset the phone to the point where I don't have to put in her Gmail after I reset the phone? That's how it works with the 7 Pro. not sure if it is the same here so just wondering if somebody could confirm or if anybody had any idea? Thanks

    That's how it generally works, unless they've changed something this gen, which is unlikely.

    Thanks. Your steps are really helpful. just want to share my experience of connecting the phone. If you plug in your USB cable before installing drivers, you need to unplug it after the drivers installed, so the MSM can detect your phone.
