Hi everyone, similar to the previous threads for
OP3, OP3T, OP5, OP5T and OP6 and OP6T, here are the EDL packages (also known as MSM tool or unbrick tool) that can revive a bricked OnePlus 7.
They can also be used to rollback your phone to a previous release of OOS.
You can download the following versions:
GM57AA tools (International firmware):

ANDROID 9:

ANDROID 10:

GM57BA tools (European firmware):
ANDROID 9:

ANDROID 10:

It supports GM1900, GM1901, GM1903 and GM1905 models.
You can upgrade to newer versions of OOS using files linked in thread https://forum.xda-developers.com/oneplus-7/how-to/oneplus-7-repo-oxygen-os-builds-t3937152 originally made by @SkandaH
Instructions:
Power your device off
Maintain volume up and volume down keys to get into Qualcomm EDL mode.
Launch MsmDownloadTool V4.0.exe.
Click on Enum to be sure your device is detected and press Start.
Wait ~300 seconds
Enjoy your brand new device
FAQ:
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.microsof...updateid=8ee52ba0-bdef-4009-88cf-335a678dd67a ) 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.
My device doesn't stay in EDL mode for more than 10 seconds
Some units can have this problem and there isn't a lot of things to do to fix that, except being fast after plugging your phone to your computer.
EDIT 7th August 2019: There is apparently a "one-off" solution to this problem available at https://forum.xda-developers.com/showpost.php?p=80021106&postcount=21 . I would like to investigate more on that but sadly don't own the device so can't confirm it.
MSM tool is stuck on "Param pre-processing"
Ensure you're using the Qualcomm drivers linked in first part of this FAQ.
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.

THIS IS AMAZING! Thank you so much. Worked like charm. No need for installing extra drivers under Windows 10 or going through some other script madness. Really smooth and easy. Thanks!

Just got my OP7 yesterday and accidentally bricked it by formatting the vendor partition in TWRP. So I was searching for an Unbrick tool but there was none.
Thank god that you uploaded this just last night and saved my OP7 from an early death :)

In order to get the EU firmware back I simply have to flash the OxygenOS for my region and that's it, right? - Worked via TWRP

Another question though: I can create files on data when I am on the phone and I can also copy files over via USB-OTG. However when I try to push files via adb it tells me that the partition is read-only. Any idea how to fix this?

Hi, I sadly have no idea about how to fix the adb push thing

Thanks for the response thiugh. I fixed it yesterdy evening.
First I tried to update the system to the EU version via local upgrade but it didn't let me as I was already on a "newer" version. So it interestingly classifies the Global version newer as the EU version for somehow.

So I went for TWRP and flashed the EU version to both slots (not even sure if that was necessary). After a reboot I was back on the EU version and also the adb push worked again. So not sure what was done to the data partition during the update, but it just worked :)

Lol. Security means your data isn't visible for 14yo boy because of encryption blabla. Nobody said it's security if he is able to steal your phone and format the storage with your personal data.:cool:
Thx
Ok. But it really make full format all phone?
If i use this msm rom i have clear device without user data, without frp etc?

Yes, it wipes everything off your device and make it like the first day of unboxing. But you can do the same by going into android settings and make a factory reset.
