Hi All,

I am trying to revive my bricked OP8T KB2001

I observe the following:
1. No image on screen, no matter what I do.
2. When I connect to my PC, I get 1 device. "KB2001" under USB
3. I cannot get into EDL mode, even I cannot turn the device off.

I tried ADB Devices, and my device is detected. I don't have USB Debugging turned on though.

I CANNOT turn the device off! If I long press VOLUP+PWR key the device reboots immediately and KB2001 reappears.
I tried long pressing VOLUP+VOLDWN+PWR but that too doesn't work.
Tried pressing VOLUP+VOLDWN with USB disconnected, then plugged in USB and release the buttons, but it doesn't work.
Tried discharging the device and then charging up from dead. It automatically turns on.

At my wits' end here. Does anybody have any idea? :/

I've found that the MSM tool works perfectly if you use it to reset a working system.
But I've also found that when the phone's in a mess it's a bit and miss, but eventuality I've always managed to get it to work.
So try this:

- Start MSM, select O2
- Hold Pwr + Vol Up + Vol Dn and
- Connect to PC (Device Manager shows Qualcomm HS-USB Loader, COM4) and release the buttons
- Hold Vol Up + Vol Dn until MSM shows connection (but this time it's always COM3) then release
- Press Start
- And away it goes

HOURS!!! I have been trying to get this to work!!! There is one KEY things that I just now remembed now that I actually read the WHOLE Tutorial Again....

Once you put it in EDL mode to install the drive, make sure you actually shut the phone for FOR AT LEAST ONE MINUTE!! I tried EVERYTHING. Ryzen 5000/3000, Intel (8th gen and also a 4th gen), USB 2 USB 3 Multiple USB cables, Multiple drivers, and nothing every time. I would ether just get nothing, or Open Serial Device Failed, or Sahara Communication Failed...Then i let the damn thing sit for a minute after installing the latest drivers (VOL + and - and Power until you get to booloader and then select power off (Vol + then power). Once i let it set for over a minutes did VOL + and - again after hitting start on the MSM tool...it...just...F'EN WORKED.....

Seeing "Automatic detection of DDR failed" and "Waiting for device" in a red font. Anything I should do? I believe I have the correct drivers installed as it's listed as Qualcomm HS-USB QLOADER 9008 (COM3) in device manager.

Nevermind! I think I fixed it but I'm not sure just yet.

This has worked for me in the past. But now, the tool isn't recognizing my device. My computer makes a noise when I connect my phone. And when I'm in Fastboot mode, I can run Fastboot commands.

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
I tried several times with the same result. I finally tried the "other 8T 5G' phone and it worked perfectly!
Well, MAYBE - it got submitted and now I have to wait 7 days for an E-Mail..

    Disclaimer: By attempting any of the processes listed in this thread you accept full responsibility for your actions. I will not be held responsible if your device stops working, catches fire, or turns into a hipster and claims to have been modified before it was cool.

    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?

    Please refer to https://forum.xda-developers.com/showpost.php?p=83448961&postcount=61, all credits to @Shadow12347 for finding it out.

    Why is my device getting in Qualcomm crashdump mode in spite of a successful download?

    Your unit was most likely manufactured after March 9th 2021, see https://forum.xda-developers.com/t/...ice-to-oxygenos.4180837/page-14#post-84789741 for reference. You therefore need to use HydrogenOS 11.0.7.12 MSM to recover your device linked at https://www.oneplusbbs.com/thread-5886794-1.html (mirrored at https://mega.nz/file/O8UySbgR#cXGlHkdA_7CYEhKIrek9zzAEwJ7Vx1D5BZdemnPlvGE by @pikatenor ). Getting new OxygenOS MSM tools is nowadays impossible unless you own the device it is meant for, so OP will not be updated to add new OxygenOS MSM tools allowing to workaround this issue. Feel however free to reach out to me in DM if you would like to get told how to maximise your chances to obtain one.

    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)

    Nevermind! I think I fixed it but I'm not sure just yet.

    I had the same issue " automatic detection of ddr failed"

    I was not able to get into fastboot or recovery and the OS was constantly in a bootloop

    I was able to get the device working using the following steps:

    1. Boot the device (let it bootloop)
    2. Ensure the device shows up properly in Device manager. (might need to disable driver enforcement in win10 )
    3. Start the MSM tool and start and let it wait for device
    4. Connect the device using the Oneplus cable
    5. It should show as connected now.
    6. Boot to edl mode using Power button + Vol up +Vol down(with cable connected)
    7. Now the MSM tool should take care of the rest

    Took me literally 10 hours to get this right. Hope this helps someone.

    Cheers.

    For those who had problem with oneplus 8t released after March 2021,this new version of MSM Tools will fix it can goes back to HydogenOS stock.After that if you prefer oxygen OS just download a update zip and update from there.
