Hello Everyone !!

A hard bricked OP3 has nothing but a black screen (nothing ever comes on the screen, not even a boot logo), it might vibrate when a power button is pressed and held for 20 seconds, has no Recovery partition, no adb mode, and no fastboot partition (It might be a flickering OnePlus logo). The device might be detected in Linux and you might be able to even send commands to it. In Windows, the bricked OP3 should be detected as QHUSB_BULK,Unknown Device,Qualcomm something. You might have a bricked OP3 as a result of flashing a kernel meant for a different device (or a ROM meant for another device that included a kernel), tinkering with the boot logo or bootloader, or your attempt of unlocking the bootloader resulted in corrupting the boot partition. Most of the times, it is needed because OEM Unlocking is disabled, and phone can't boot and no recovery.

The solution for OP3 hardbrick is similar to OPO - you just need a Qualcomm driver and a recovery package. A very very big thanks to some guys at XDA who got these files (don't know how) (I have modified the method 1 file though the method 2 file is exact file from OnePlus) and helped all of us to get out from one of the most weird state of the phone. Thanks guys. ( @CyberCROC and 1 more)
METHOD 1

This method is the best method and will not wipe your data at all and will give you stock recovery+latest OxygenOS (or the ROM you were on) and bootloader will remain in the state it was earlier.It *might* not work if some other partitions were also corrupted.

Step 1 :- DOWNLOADS :-
1.) Drivers :- https://www.androidfilehost.com/?fid=24052804347799753
2.) Recovery Tool :- https://www.androidfilehost.com/?fid=24591000424942611
3.) [OPTIONAL :- Will be required only if you don't have a working system] Latest OxygenOS :- https://www.androidfilehost.com/?fid=24591020540821926
Step 2 :- Extract Drivers and Recovery Tool files on Desktop.
Step 3 :- If you are using Windows other than Windows XP,turn off Driver Signature Enforcement.To do so,follow this guide :- http://www.howtogeek.com/167723/how-...igned-drivers/
Step 4 :- Press the power button for 40 seconds to turn off the phone.
Step 5 :- Press only volume up button for 10 seconds and while keeping it pressed,connect your phone to PC.Keep volume up pressed till your device shows in device manager as [Unknown Device,QHUSB_BULK (under Unknown Devices) or Qualcomm HS USB ...... (under COMs and Ports)].
Step 6 :- Right Click on your device in the device manager and select Update Device Software. Choose the .inf file manually from x86 or x64 folder as the case implies and select Qualcomm 9008 from the listed devices.If you are unable to see 9008,see the end of post for various other methods to show Qualcomm 9008.
Step 7 :- When the device shows as Qualcomm 9008 ,go to the extracted Recovery Package and run the MSM Download Tool as administrator.
Step 8 :- Click start at top left corner and wait for it to finish (green text will come).
Step 9 :- Disconnect phone from PC and boot into system.
........................NEXT STEPS ARE TO BE FOLLOWED ONLY IF YOUR OP3 DOESN'T BOOT INTO SYSTEM STILL BUT IS STUCK ON ONEPLUS LOGO..............................
Step 10 :- Boot your phone into recovery (Power+Volume Down).
Step 11 :- Click on Install Update.
Step 12 :- Install adb for windows system-wide if not already installed :- http://forum.xda-developers.com/show...php?p=48915118
Step 13 :- Navigate to the folder containing Latest OxygenOS Zip. Shift+Right Click anywhere in the folder and Open Command Window.
Step 14 :- In the command window,type :-
Code:
OnePlus3Oxygen_16_OTA_008_all_1606122244_e0cfc5ffc8bf411a.zip
and wait for it to finish.Then reboot into system.


METHOD 2

This method is easy to use and flashes OxygenOS 3.1.2 on your phone. It wipes all your data (See end of post on how to not wipe data) and restores all partitions to stock. It will work in any condition unless it is a hardware damage.

Step 1 :- DOWNLOADS :-
1.) Drivers :- https://www.androidfilehost.com/?fid=24052804347799753
2.) Recovery Tool :- https://www.androidfilehost.com/?fid=24591000424942573
------------------Follow Step 2 to Step 9 from Method 1 --------------------


How to Prevent Data Wipe in Method 2



Step 1 :- Extract the Recovery Tool.
Step 2 :- Open all rawprogram...........xml through Notepad++
Step 3 :- Delete all userdata........ lines from the xml file.
DONE !!!



How to Make the device show as Qualcomm 9008



1.) Make sure driver signature enforcement is disabled.
2.) Try these drivers,one of them might work too :-
https://www.androidfilehost.com/?fid=24052804347799753
https://www.androidfilehost.com/?fid=24269982086990168
https://www.androidfilehost.com/?fid=24349802275800175
https://www.androidfilehost.com/?fid=24349802275800173
https://www.androidfilehost.com/?fid=24349802275800171
3.)
Download this :- http://www.mediafire.com/download/4a...6wc67/Qualcomm 1.00.11.rar
Keep phone disconnected from PC.
Open the folder "qc" and install the Test Certificate in the following Stores: Trusted Root, Trusted Publisher, Third-Party Root and Personal
Run the Qualcomm setup wizard (also located in the qc folder)
When completed, restart your PC again with Driver Signature Disabled. (Optional but preferred)
The driver should now automatically install. If not, go to device manager and right click "Unknown Device" and click "Update Driver" Search up the QC folder and press ok. The driver should now install.

Definitely not possible. I have tested it myself on a friend's device. What was the status of the phone before ?

Phone booted into fastboot previously but could not boot to recovery. You can say what you like but my phone does not respond now. Going to continue working on it but all steps were followed.

Can you please try once again ? In no way can it damage the phone . The method 2 file is the complete one, it is almost uploaded. So, you can try that after. But, method 1 file should definitely work.

I have tried it 8 times now using both drivers from Method 1 & 2. The phone now has no response. I get to the MsmDownloadTool and click start and I get 2 errors in red popping up after a few minutes of downloading. The phone now has no response, no vibration or lights. Screen won't even come on.

Ok, OPO Tech Support just fixed my problem with a login. I'm not sure if it's a different driver or the device signatures but they got it working.

No need. We found the issue. It will be issue for those who also got system partition corrupt. For those guys with corrupt system partitons too, use Method 2. The file has almost been uploaded.

My device is now unusable (Screen won't come on, no lights, no sound and no vibration)

The only positive is that it appears/disappears from device manager as Qualcomm 9008 when I plug/unplug it from my PC
