I see there is some confusion here.

Basically there are three types of builds for OnePlus 7T:

HD65BA (EU firmware)

HD65AA (India firmware with letter I in ro.build.version.ota value of your build.prop )

HD65AA (International firmware with letter O in ro.build.version.ota value of your build.prop )

You can switch to the firmware you want using files present in my mirror thread using local update feature in Settings --> System --> Updates

If you want to root your current version of OOS, you need to flash the relevant Magisk patched boot.img meant for the firmware your device is running :)
[OnePlus 7T Guides, News, & Discussion] ErwanChme:
Oooooh I see :D

But last question where can I find build.prop ? I have to flash with the version I want to know the version? :)
[OnePlus 7T Guides, News, & Discussion] Some_Random_Username:
Assuming you have ADB installed on your computer and USB debugging opinion enabled in developers options of your phone, use adb shell getprop ro.build.version.ota in a command prompt to know what firmware you're currently on.
[OnePlus 7T Guides, News, & Discussion] ErwanChme:
Ok thanks u helped me a lot I try this when I back home :D

i used tool on my hd1903 to get back to 10.0.4 hd65aa global from 10.0.5 hd65aa global so i could local update to 10.0.4 hd65BA EU and it wont let me says i cant downgrade even though its same build just want to switch back to eu but it just wants me to update to 10.0.5 global via ota i thought you could go back and forth via local update if same build , anybody else had same issue
[OnePlus 7T Guides, News, & Discussion] tkt40:
This worked like a charm. You're awesome!

I too bricked my device trying the unofficial twrp. I stored the phone away until a usable twrp was made. I followed your instructions and needed to update my qualcom drivers in order that it could be detected. It worked beautifully! I'm now back to square one. Thanks!!

I see neither QDLOADER 9008 nor QHUSB_BULK in my device manager and my device is not detected by the MSMDownloadTool. I do see, however, a Kedacom USB device in my device manager titled "Android Bootloader Interface". I just want to be sure that I should download the driver you provided onto my phone before I brick it any further.

[OnePlus 7T Guides, News, & Discussion] morback:
Can someone tell me if this tool allows to actually modify the phone variant? I mean is it possible to convert an hd1900 to European variant?

I know it's possible to load any kind of rom (OOS international, EU, US, India, H2OS...) but my question is relative to variant model. HD1900 has not been certificates for certain bank apps to work with NFC payments by instance.
[OnePlus 7T Guides, News, & Discussion] michelemascia7:

Can you check if your build Number Is still HD65BA? In this case you have the EU firmware. You can find it in: about phone - build Number. Thanks
[OnePlus 7T Guides, News, & Discussion] anzial:
does this reset the entire phone, including bootloader and not just the firmware? I'm worried about any potential malware on a pre-used phone
[OnePlus 7T Guides, News, & Discussion] Lost Dog:
This strips it down to the bones.... Nothing should be left as it was. It takes you from whatever version you are on (probably 10.0.6) and drops you down to 10.0.4. I believe since bootloader needs to match rom version you can't have a 10.0.6 bootloader with an older build.

[OnePlus 7T Guides, News, & Discussion] abalam:
Make sure that the program is already open and that you are full of up and down for at least 15 seconds. If you first run EDL and then start the program, it often gives an error message.

Thank you very very very much bro for this! Just fixed my bricked oneplus 7t. I don't know what would I do if you didn't release this tool! Thank you again..
[OnePlus 7T Guides, News, & Discussion] mikefnz:
Not having much luck

Any advice greatly appreciated....

I started with an update problem rolling from 10.0.6 to 10.0.7, and lost root. Then tried to flash the original patched 10.0.6 Eu version (1903).

Then no sound no wifi.

Tried this tool. Got the sahara failed message and now the phone appears dead.

No response from power button at all. Perhaps I pressed the up/down button too long?

Never had these types of problems with my old Pixel XL.....

Any suggestions?

Update - fastboot mode only now.
[OnePlus 7T Guides, News, & Discussion] abalam:
If you put in bootloader menu, turn off phone from bootloader. Start the tool already !! Hold up and down for at least 20 seconds and then connect it with the original cable. Now the tool recognizes the phone.
[OnePlus 7T Guides, News, & Discussion] mikefnz:
Thanks for the suggestion but I managed to kick the phone back into life by eventually flashing an older version that had been unpacked and then updating. Although I'm sure I've gone from an AB version (I think) to an AA version and Google Pay still thinks the phone is rooted when its not. I may yet have to do this to get a completely clean start!

Perhaps I should be patient and wait for a fully functional TWRP...

Cheers

[OnePlus 7T Guides, News, & Discussion] Some_Random_Username:
Turn your device on, turn it off, get back to EDL mode and retry.
[OnePlus 7T Guides, News, & Discussion] ldeblir:
I have the same problem. Grr! Phone reboot after 15 secondes when is in EDL mode.

I tried this way:

- no cable connecter, device off

- Volume up & down pressed about 5 seconde

- while pressing, I connect the usb cable

- MsmDownloadTool, detect the device (Windows usb notification sound)

- release Volume up & down

- Phone reboot after 5 or 10 second...

Maybe I doing it wrong. ?
[OnePlus 7T Guides, News, & Discussion] north.vill.44:
Sorry,

I did not know how to enter EDL mode from power off

but,

If you can use the adb command

1.device - Normal startup

2.device - Ready to use Oxygen OS

3.cable connect

4.PC - run, MsmDownloadTool V4.0.exe -- Status is N/A

5.PC - run, adb reboot edl

6.After this, only about 15 seconds -- Status of MsmDownloadTool is Connect

7.After this, Display of unlock warning screen

8.After this, if nothing is done, it will start normally

If you want to do MsmDownload

Press START while the status of MsmDownloadTool is connected

[OnePlus 7T Guides, News, & Discussion] Some_Random_Username:
MSM tool detects automatically which model you have. I mentionned them in first post only because there is also a variant sold by T-Mobile in USA, which requires a different version of the tool.

Regarding your second question, as I said in second post, you have to select by yourself build you want to restore your device to.

Not sure why you're all upset about this. It just makes more sense to keep these tools together in a single thread than scattered about. You could of just posted the links in this thread and be done with.

Mine is bricked now, too. Just wanted to relock the bootloader and now get the message "Your device is corrupt. It can´t be trusted and will not boot"

I can enter fastboot, then reboot into stock recovery (seems so at least..) but I didn´t make it into EDL mode. Pressing Vol+ and Vol- and then put in USB cable into PC or also pressing Vol+ and Vol- and Power did not work. I´m everytime entering fastboot mode then. Since device lock status is locked there´s also no possibility to use FASTBOOT ROM. I tried but every single steps results in FAILED.

Any chance to revive my device from that state? Drivers shouldn´t be the problem, phone was installed and recognised before already, as it was rooted and TWRP was installed, too.

Thanks in advance für ANY hint or help!!
[OnePlus 7T Guides, News, & Discussion] Josh McGrath:
Have you tried going to recovery, rebooting to bootloader then selecting "power down" and then booting to edl mode via hardware keys?

Edit: also may try fasboot edl mode...not sure the exact command but look it up and try it in bootloader mode
[OnePlus 7T Guides, News, & Discussion] kischde:
That's the only way to get into EDL I thought: from powered down holding Vol+ and Vol- and then plug connector into USB slot. I also tried both Vol and Power button together.

From fastboot mode I also tried 'fastboot reboot edl' but device returned unknown command or something similar (don't remember the exact words). Interestingly: I could reboot from fastboot into stock recovery. But after reset data next reboot ends with looped 'Your device is corrupt' again.

I had that same issue with even after reset it would still not boot myself but this was before the msm tool was released. I ended up having to doing an exchange.

I also have seen a few 6t/7t ship with broken edl mode and have to be swapped out as well. (Which is weird cause how did they load the os from the factory then)

Followed the thread (hold Vol+ and Vol-), attach to USB, launch MSM, click enum to see connection, once connected start the download. I got an error Param Mismatch, that elapsed in 5s. I stopped the download, and disconnected the phone. Now when I attach to USB, i get the error "usb device not recognized." If i try to turn on the phone - nothing. If I try to charge the phone - nothing. If I try to get back into EDL, nothing.

Device seems completely bricked.

PLEASE can someone help.

Not too sure what happened. After leaving the device disconnected for some time, I held volume up and power for 10-15 secs and lo-and-behold - the device started up. Looks like I used the wrong unbrick tool - didnt see the difference between OP7PRO and OP7T.

Hm, when I try to replace the Kedacom drivers (I tried with the internet disconnected too), when I search for the qualcom drivers it just says it's already found the best drivers.
