Your phone will reboot into the HydrogenOS ROM. You should see “Download Complete” when it is done unrooting your OnePlus 6 from the hard brick state and your phone will automatically reboot. Once flashing starts, it should take around 5 minutes.

If you don’t see it, try rebooting your OnePlus 6 by holding down the Volume Down and Power buttons for about 20 seconds until it vibrates then immediately hold down the Volume Up and Power buttons again to enter the Qualcomm MSM mode. You should see “Connected” under “Status of Connection”. Now, you can check that you are in the Qualcomm MSM mode by unplugging your phone and plugging it back into the computer and your Windows computer should make a beeping sound like shown in my video tutorial. If you have trouble, just reboot your device using fastboot menus then immediately hold down Volume Up and Power buttons. If done correctly, you will hear your Windows computer making a sound like when you connect a USB device. Then hold down Volume Up and Power buttons together and you won’t see anything but a blank screen. Power off your phone then connect a USB cable from your OnePlus 6 to a Windows computer first. You need to put your phone in Qualcomm MSM mode. If above 2 unroot method fail and you are still in a bootloop state(and believe me, it can happen as it happened to me last night), you will want to use the hard-brick unroot method outlined here:

There are times where your rooted OnePlus 6 may be in a permanent bootloop situation.
