Hii XDA fellows,

So I have seen many people asking for noob friendly guide to restore original oxygen os firmware or basically unbrick device. There are several thread on this already but trust me I have tried them all and in my case I had to use my own brain. So I have compiled a noob friendly guide which I,myself have used to unbrick my device.

small warning this will wipe all of your data.

Firstly I wants to thank Some_Random_Username for bringing up MSM Unbrick tool for OnePlus Nord. His guide to unrick nord is also fairly good enough but in my case I was stuck in bootloop after installing a rom. My phone was not even booting to Qualcomm EDL Mode so that I can use MSM Tool.

Lets start with pre-requisites:

You must have unlocked bootloader.

Original Oneplus Type - C cable.

Windows PC.

ADB debugging turned on your phone.

Firstly Switch off your device, which I think most of you have already have as the device is bricked but in case your phone is stuck in bootloop or recovery or bootloader menu itself then try holding down voume up button and power button together hold them down till you get heptic feedback and screen goes off. Let it be cool down for about a minute.

Now Setup your PC:

Download MSM tool to from this guide : Click here

Setup adb environment in your PC if you havent already setup follow this guide

Download Qualcomm EDL drivers from here: Click here

Now download Unofficial TWRP recovery by Mauronofrio from here

On your PC right click on start menu icon and start Windows Powershell(Admin) and type this command bcdedit /set testsigning on This will turn off driver signature verifications on windows you will be required to restart your pc now after you restart your pc will boot into test mode and you'll see a watermark stating the same in bottom left of your desktop. Worry not we will undo this after we have finished restoring.

install Qualcomm EDL drivers by running the setup listed above.

Unzip MSMTool there you will see a file named MsmDownloadTool V4.0.exe run it, it'll take some time but after you see a pop up asking for user type user name and password, Select other as user type and leave other stuffs blank as it is and click next.

In the next window, In the target button select O2 while using global tool or India while using indian tool or EU when using european tool.

Now you have to boot into Qualcomm Emergency Download Mode

You can do this in several diffrent ways but one I am listing here is recommended :

Boot into fastboot/bootloader mode by pressing and holding Volume up, Volume down and power button together when you see a Menu pop up on your screen you can let go all the fingers at once.

Now connect your phone to your PC and go to that folder where TWRP recovery is located. Hold Shift button and Right click inside that folder you'll see an option "Open powershell window here click on it. In the powershell window type

fastboot devices and press enter your device will be listed as fastboot devices in powershell window. Now type

fastboot boot twrp1.img press enter

your device will boot up in TWRP recovery in twrp recovery go to reboot section and select Edl, This will boot your phone Edl mode your screen will go off as soon as it happens in the MSM tool window you'll see a device listed as com3/com5/com7.

Click on start button the restoration process will begin. Wait for about 400 secs and your device will automatically boot up.

Voila you've successfully unbricked your phone.

If you want to exit from Driver test mode on your pc simply start a powershell window with admin rights and type

bcdedit /set testsigning off

and restart your PC.
