Ok cool. Well if you need them, here are the Qualcomm drivers for ya. https://www.thecustomdroid.com/qualcomm-hs-usb-qdloader-9008-drivers/
I am sure I have used MSM on USB 3.0 before as I own a MacBook on which all ports are USB 3.0.
You need a pc with usb 2.0!
To un-root & Lock the bootloader, Qualcom driver it's NOT the most important thing!No Qualcom 9008 driver in Device Manager.(win.10 pro_x64 with the latest updates). I tried to update, both auto & manual. Not working.
For Locking the bootloader i tried first Tool from Mauronofrio, then with ADB (drivers, adb/fastboot installed). Still does not see the phone in Fastboot/bootloader mode. With the phone ON, yes.
In MSM app Android 11 shows " Not connected". I read online that could be some problems with android 11.
I downloaded MSM Android 10 , now it shows "Connected", but does not show OnePlus or anything else. I said what the hell, press Start.
It worked. Nowi am Locked, no root on Android 10.
I plugged in OTG flash drive. Copy Oos 11.0.77 to root of the storage. Flashed.
Now i am on Android 11.0.77 Locked, no root. Ready to sell the phone.
My phone is european version. In MSM i selected EU, of course.
still no luck? I have a 8t+5g that I converted to EU with the msm tool and then tried for days to learn and understand the syntax to fash a LOS. I finally succeeded but it was my first time and I mad a mistake by flashing the twrp instead of booting it(at least I believe that was the mistake). I ended up with a bootable LOS but it was corrupted and when I later whenI was coming out of a fastboot mode the OS wouldnt boot. So I have had a similar experience. I used the MSM tool to reflash an INDIA oxygen, and now my device is fine. Dont know if the syntax is exactly the same, but I noticed you tried oem edl. Have you tried adb reboot edl? or if your in fastboot mode and you have a recovery, trty to fastboot into recovery manually or through command prompt and enable adb and issue adb reboot edl command. that might work for you.
They are on the First page. You need the AA versions
