Accidentally bricked my phone while trying to unlock the bootloader on my phone. I was doing this in an attempt to root my phone again after removing the root in an attempt to update Oxygen OS. After TWRP was unable to flash the update I gave up and tried to root the phone again using kingo root but kept failing. I checked whether or not the bootloader was locked and sure enough it was but after attempting to unlock it again, the phone was bricked and could only go into fastboot mode. Flashing the stock OS didnt work since the bootloader was locked. I tried using a unbricking method posted to oneplus forums that invloves downloading qualcomm diagnostic drivers and using a unreadable download tool but couldn't find the driver the method mentioned Qualcomm 9008. After some more searching other methods were similar but used the driver Qualcomm HS-USB Diagnostic 9006. Once that driver was installed i launched the MSMdownload tool which was taking hours with no progress bar whatsoever so i decided to go to sleep. I woke up to an unreadable notification from the download tool and my phone's battery was dead. The phone wouldn't go into fastboot mode but was still being detected in device manager. All the phone responds to is the power button and volume down button being pressed which just causes the phone to display a low battery notification and then stops charging a minute later. I then tried using an unbricking method that involves installing the qdloader 9008 driver and running a program called QFIL but this method failed to unbrick the phone. Is there any way to factory reset my oneplus 2 and put the stock OS back on to it? please keep in mind that the bootloader is locked. i cant post links to the methods i used as the site wont let me
