[OP8T][OOS KB05AA/BA/DA] Unbrick tool to restore your device to OxygenOS

Search This thread
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.
close, but no cigar.

more reliable to get MSM to see it, but fails with the "Automatic detection of DDR failed"

always 23 seconds in using USB2 or 3 ports.

running the windows 7 version it fails the DDR check @ 10 seconds.

In any case, when it fails the DDR type detection, that's it.
 
What's really interesting, is that I was able to easily use the Lineage 18.1 recovery to reinstall LineageOS.

MSM seems a crap shoot gamble.

Easy to get it to connect, but it always fails in detecting the DDR memory type...


I wanted to go back to OOS 11, then just root, safetynet, exposed so I could end up with everything I want. It sucks that the MSM tool is so finicky or poorly written.

it definitely doesn't like my 1+ 9 Pro (global model) even if I use the same original USB C cable that the phone came with .. the same cable that works perfect to transfer files, ADB, or FASTBOOT, installing LineageOS 18.1 or crDroid the first time everytime...

Now it appears I am stuck without the ability to revert to OOS 11...

Have you used the earlier firmwares?

I had issues but mine seemed to be internet connection related, though.

Not sure what firmware you are talking about... some people interchangeably use ROM and Firmware...

My internet is symmetrical 1Gbit fiber, so it's not internet related.

This is an issue with the MSM application or phone I am thinking, because it fails the same DDR identification whether I use a USB2 or USB3 port, no matter which cable I use.

In any case, I flashed the LineageOS 18.1 ROM back to the phone, and it's usable at least.

I can't see a cable being the issue if it's able to flash gigabytes of ROM OS with the same cables. That leads me to believe the issue is phone or MSM tool.

Anyway, for tonight I am setting down the phone and relaxing. Thankfully I have a secondary phone.

Have you toggled the DDR tab on the top and see if that helped/worked?

I used an earlier firmware to flash (it didn't have the DDR tab) that worked for me from there I just upgraded to the latest available version locally.

That file might be located on the other thread.

That's pretty much what I did. Went to the 4.0.0 one for India... It all came back with English locale, updated once to bring it to the last A11 update... using it that way now.

you can use the official way to downgrade from oneplus:
you need to download both an apk and install on the phone and a rollback package.
I used this method sucessfully to downgrade to OOS11
note that i sent the link for oneplus 8t if you have a different OP phone search for another link

Hi everybody,

I'm experiencing some trouble, today I manage to make the android 12 update, I lauch the install by internal updater everythings goes done exept when the phone reboot. It start bootloop on OOS logo and nothing come back.
More than 5min later I turn it off and retart, same bootloop, I can go to recovery and fastbootmod, so I try to switch between the two installation slot android 12 is on A and I switch to B... Now it bootloop immediately and I can't go nowhere (I do that to have a chance to recover all my data, but it's worse).
So I resigned myself to do MSM recovery, but I can't connect the phone to computer properly.
When it is on bootloop the only way to stop it is volume up + power during few sec, after that, I follow post instructions start MSM, volume up + volume down usb plug etc
But nothing come up and phone bootloop everytime.
I try every usb port of my computer, installed qualcomm driver, my phone is never recognized by my computer so I'm running out off solutions....
If someone have a idea....

Thanks

Yes I've uninstalled all drivers, then shutdown the smartphone, link to pc and working. I've a second theory, That I tried in the same time (so I don't know if it was a driver fault or this second one). You need to enter in another "mode", not fastboot. I discovered it on a video, because in this guide it was not clear. Didn't find it but search on YouTube. Seems you need to enter in this mode, the screen remains black, link to pc, and the MSM recognise it.

Hi, my EU 8T is bricked, powering up gives me the 'image destroyed' error, but I can still get to bootloader. Whenever I try to run MSM the process fails at 'Param Preload Failed'. I've tried the newest and oldest OOS links, and the HOS one for newer devices, and all give me the same error.

I've tried W10 and W11 on two separate machines, rebooting into unsigned driver mode, and MSM always fails at the same point. I've tried the OnePlus cable and other USB-C cables in 2.0 and 3.0 slots as well.

i've also tried using the payload dumper method but that doesn't work either.

Any help gratefully received!

    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.....

    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)

    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.

    Did you end up finding a solution for the "Automatic Detection of DDR failed" issue?

    ---------- Post added at 06:54 AM ---------- Previous post was at 06:51 AM ----------



    Sorry to spam, did you find a solution?

    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)

    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.
