This OEM has always been quick to release its kernel source code. As a result, all its devices have been quick to jump into custom development. Along the same lines, it has long-lasting support in this domain. While it has been more than two years since its launch date, yet there are still a plethora of mods and tweaks coming up every now and then. Furthermore, we are already seeing many Android 11 custom ROMs for these devices as well. To carry out all these tweaks, there is just one requirement: your device requires an unlocked bootloader.

Once you do so, you have literally opened the floodgates to the plentitude of customizations. In this regard, having the administrative rights for your device by rooting stands right there at the top. This could take two different approaches. We have already covered a guide to root OnePlus 6/6T via TWRP. However, not every user prefers to install TWRP Recovery but still wants to root their device. If you also echo these thoughts, then this guide shall help you out. Given here are the steps to root your OnePlus 6/6T without TWRP via Magisk patched boot.img. Follow along.



Benefits and Risks of Unlocked Bootloader & Root

Once you have unlocked the bootloader on your device, you could flash custom ROMs or even a custom recovery like TWRP. This in turn will allow you to flash ZIP and IMG files, create and restore Nandroid backup, FIx Recovery Bootloop and carry out many other tweaks. Along the same lines, you could also gain access to the system partition by rooting your device via Magisk. Once rooted, you could the flash magisk Modules, Substratum Themes, Xposed Frameworks, and other related mods.

However, these tweaks do bring in some uninvited guests (aka risks) as well. To begin with, the process might make the device warranty null and void. Likewise, it will also wipe off the data partition, and hence all the data on your device. Furthermore, apps like Google Pay and Netflix might not function as expected (Fix given at the end of this guide).

Likewise, you might also face a few issues while installing OTA (again Fix is given at the end of this guide). In no manner whatsoever will Droidwin be responsible in case of thermonuclear war or if something happens to your device by executing these steps. So if you are ready to proceed ahead, then here are the steps to unlock the bootloader and root OnePlus 6/6T without TWRP via Magisk patched boot.img.



How to Root OnePlus 6/6T without TWRP via Magisk patched boot.img

The entire instructions are broken down into separate sections for ease of understanding. Make sure you checkmark all the requirements mentioned below.

STEP 1: The Prerequisites

  • First and foremost, take a complete device backup. The process will wipe off all the data from your device, so having a backup is a must.
  • Likewise, enable USB Debugging and OEM Unlocking on your device. The former is required so that your device gets recognized by your PC in ADB Mode. But why would you need ADB Mode? Well, it will be needed to boot your device to Fastboot. And Fastboot is required for unlocking the bootloader and flashing the patched boot.img file.
  • On the other hand, OEM Unlocking is needed to carry forward the process of bootloader unlock. With that said, head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.
