Unrooting Oneplus 8T - OnePlus 8T Questions & Answers

Hey guys, I want to unroot my phone and lock the bootlodaer.
downloading the latest software from OnePlus's site and flashing with local upgrade in the system updates setting should be enough? (and of course locking the bootloader afterwards)
Or should i take more steps like uninstalling magisk and restoring images?
Thanks!

Doesnt MSMTools restore the phone to original settings?

Quick question, the oos version listed there is older than what I have currently.
Can I just download the latest version from Oneplus's website and use that?

Download the latest MSN tool flash it as it mentioned in the instructions and after it boots update via OTA to your latest OOS
Remember that you download the MSN tool for your phone

MSN tool can't seem to detect my phone any idea why?
It seems I triggered the edl mode as the pc detects qualcomm instead of oneplus as the device.
for now i booted the phone normally

Have tap the enrum button ? And your PC detected right in edl mode your phone should listed as Qualcomm 9008 when I remember right and in MSN tool should it shown as detected if not tap the enrum button in MSN tool

I did not tap the enum button as it said nothing about that in the tutorial.
The device was not detected as Qualcomm 9008 it was Qualcomm and a lot of letters and numbers.
I will try again with the enum button later when I don't need to use the phone

You phone must be listed as
QDLOADER 9008.
If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed. Look how is it listed if it not QDLOADER 9008 then drivers are missing

if it is listed as QHUSB_BULK how can I install the driver?

As i write before, read this >>>> https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180837/ carefully and follow the instructions, all is inside in first post. You need the Qualmcomm drivers, the download is mentoined and linked in this thread.

[Q] restoring bricked oneplus one problem

First of all, when I'm in the wrong thread, sorry!
So here I go. I guess i bricked my 1+1. Doesn't turn on, only black screen and if i push a button, it vibrates. Looked up for solutions, and found one here somewhere. It's with the recoverytool or with ColorOS.
So I tried to follow the steps. Everything works fine, in Device Manger, the phone is now recognised as Qualcom HS_USB QDloader 9008 (COM3). Til here no problems at all. Then I installed the set-up file, compatibilitymode, run as admin.
I open the recoverytool, and i scan for the device. It should appear as COM. But nothing shows up. It's weird because Windows recognises the device.
What am I doing wrong? What can help?
Thanks

Have you installed the Qualcomm driver?Its very tricky,Windows wont allow to install it easily.
Yes I did, I was able to switch to non signed in Win8 via F7 in a menu. Thats why it changed from BULK to qualcomm qd9008 on a COM port. Or cant I be sure its done propermy when the name changed?

The easiest way for unbricking oneplus (yes, I tried it): http://forum.xda-developers.com/showpost.php?p=55024864&postcount=136
ColourOS firmware has all needed files for proper flashnig, including right tool for doing that.
Only thing that didnt work on my Win 8.1 x64 was drivers mentioned in post above.
I had to use this QHSUSB_DLOAD drivers from member DallasCZ (that I used for unbricking ZTE v9180). Only with that drivers my Windows recognized bricked phone and Flash tool could find and flash it.
Flash tool in only on chinese, that is a bit problem, but instructions given in post I linked are more/less usefull.
This is a link to DallasCZ shared folder with qhsusb drivers:
https://drive.google.com/folderview...&usp=sharing&tid=0B1T7tp6tJ_3kQkZSWjNsazJZbGc
If you are sure the driver is okay,plug in the usb cable and out and in,until you see the green line on the tool.Also you can follow the guide as in below link:
http://forum.xda-developers.com/oneplus-one/general/tool-oneplusrecovery-tool-v1-0-restore-t2991851
The same thing but this time you can flash CM11s instead of ColorOs.Also there is a video.Pls check it.
Ok so I did the process over and over again, the sixth computer did it right! I was back on ColorOS and now back to CM11S.
This thread can be closed, thanks for the help!
No problem,glad to hear you solved the problem

I really need urgent help!!!

i made a huge mistake guys i was trying to flash twrp recovery and then it didn't work and the phone bricked so i tried to download all in one tool and then by mistake i locked the bootloader and then i downloaded the msm tool and its not working my windows is in test mode and every time it says sahara communication failed :crying: :crying:

First of all you don't need to panic... Panic is the worst advisor and it doesn't solve no one problem
Of course if you had an unlocked Bootloader the device could be restored in various ways,that are now excluded
Your device is "T-Mobile" or is it locked maybe to a provider? What device you have? For example is GM-1900,GM1910,GM1911 etc? The device only enters in Fastboot mode?
What version windows10 you have ? (home,pro,Pro N etc)...

I think the mainboard is broken , it’s time to say goodbye to my U11.
Thank you
Make sure to delete all other drivers and then make sure you install the correct HTC drivers, any other driver that isn't the correct HTC can and will interfere with you trying to run ADB or fastboot commands.

The device does not run on black screen

Greetings to all
After flash rom on fastboot and rebooting the device, the device entered the recovery, but the recovery is not working just black screen
I have pressed the power button and volume down button for a long time but nothing works
Currently the device is completely damaged!!!
I want to get into the bootloader in any way

I'm not sure what your ROM installation process was, however at this point sounds like you need to use the MSM tool and recover your phone.
Unbrick tool to restore your device to OxygenOS <-- Use this thread.
Also from that thread:
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.

Drivers are in that thread.
Screen will be blank / off during this process when you are in this mode (what you are seeing). At least that is what I believe you are describing / seeing.

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.

OnePlus 8T+ 5G T-Mobile KB2007
My phone has become a brick. 3 days have been trying to restore it. Can't find the solution...
What issues I have:
- no "QHUSB_BULK" in Device Manager
- no "Qualcomm HS-USB QDLoader 9008" in Device Manager
- MSM tool doesn't see my phone
- EDL mode doesn't load
- fastbootd doesn't load
- all fastboot roms show a lot of errors during installation
Works only usual fastboot.
What can you recommend me to try? Thank you!

It might help if you shared what you've actually done (what you did that resulted in bricking and what you've done to try fixing things) in detail. Include versions of software and source.

It's complicated, because I tried a lot of ROMs from this forum and from other sources... The main problems, that MSM doesn't see my phone if I want to install ROM through MSM, and Fastboot give a lot of errors, if I want to install ROM through Fastboot...
How I brick my phone? I used file from OnePlus to unlock the bootloader (before it I unlock my phone from T-Mobile). After that all my data was wiped and I decided to change ROM from T-Mobile's to Global. I tried one of the ROM's (I don't remember which, but one from this forum). And my phone became a brick. (previously in my life I reinstalled a lot of ROMs on my Samsung Galaxy S2, Samsung Galaxy S4 - and have no issues, but this time...)
Use EDL to recover. You can get to fastboot, so you are not hard bricked. Make sure drivers are installed properly, try a different computer/cable

It seems, on PC side of things you don't have drivers properly installed, otherwise you wouldn't have
- no "QHUSB_BULK" in Device Manager
- no "Qualcomm HS-USB QDLoader 9008" in Device Manager.
For the same reason, i presume MSM doesn't see your phone.
