OnePlus 7T Pro is the latest big name in the smartphone market and as expected, it irons out all the tiny flaws that the OnePlus 7 Pro had. Not only does it have a QHD+ 90Hz display like many other flagships, but it also gets its juices from a Snapdragon 855 Plus chipset, something even the latest Pixel 4 doesn’t equip.

While that’s already more raw power than you need to run the phone, you might want to notch it up a little by getting access to root privileges on the OnePlus 7T Pro. We already have a guide to root a OnePlus 7T without TWRP and now we have compiled a workaround to get root access to OnePlus 7T Pro without TWRP recovery.
