If you’re wondering, unlocking the OnePlus 6T bootloader is not a complex process and basically it can be completed in less than 5 minutes. That’s possible because this new OnePlus branded device shares the same hardware and software platform with the OnePlus 6, which already received different tweak support from those of xda-developers. Anyhow, as already outlined, if you want you can easily and quickly unlock the OnePlus 6T bootloader and in that respect we are here to assist you – the unlocking procedure will be explained during the following guidelines.

As you might already know, the bootloader is a specific Android script, a small program that runs by default on all the Android based smartphones and tablets. This program is there to make everything work which means that your OnePlus 6T cannot run without it. This script will be launched each time you will choose to boot, reboot, power off or power on your handset. During those processes the bootloader will load the Android OS along with other start-up programs and features from the ROM memory into the RAM partition.

So, why an unlock procedure is discussed in this case? Well, by default the bootloader is loaded with different factory restrictions. These restrictions will prevent you from initiating further tweaks within the Android core system meaning that you cannot customize, optimize or personalize your OnePlus 6T by applying dedicated custom operations. So, if you want to change that and if you want to gain full control over the Android UI, then you must learn how to unlock the bootloader first and that will be explained during the steps from below.

Of course, unlocking the OnePlus 6T bootloader isn’t an official operation. You will lose your phone’s warranty if you will choose to resume the rest of the guidelines from this tutorial. The warranty flag can be restored if you choose to revoke the recently applied tweaks which can be achieved by reinstalling the stock Android OS – as you can notice then the bootloader will be relocked.

In case you’re wondering, on an unlocked bootloader you can initiate various tweaks and unleash the true potential of your OnePlus 6T. And, here are some examples in that matter: you can install a custom recovery image such as TWRP or CWM recovery; you can gain root access by setting up Magisk or by flashing SuperSU; you can remove bloatware and add custom apps from other sources than Google Play; you can update your Android device with custom ROMs such as Lineage OS, AOKP or Paranoid Android, you can make Nandroid backups for saving the current Android OS; or you can overclock or undervolt CPU frequencies.

You should backup your OnePlus 6T before choosing to start the unlocking process that’s explained below. The backup will help you secure your personal files, which might get corrupted or even wiped out while you try to unlock the bootloader. A general backup can be easily applied and your device you can do it by using built-in cloud storage services, by syncing data with your Google Account or by using dedicated backup and restore apps from Google Play – in that way you can successfully save stuffs like contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, EFS folder, IMEI / NVRAM data and so on.

This is a manual operation that can be applied only if a computer is at your disposal. The OnePlus 6T drivers must be installed on that computer first, where the Android SDK toolkit must be set up too. You can learn how to configure Android SDK by using our dedicated tutorials: how to install Android SDK on Windows or how to set up ADB on MAC OS X / Linux.

On your smartphone you have to become a developer – repeatedly tap on Built Number until you receive the ‘you are a developer’ message (this prompt will be returned after 7 or 10 repeated taps). Afterwards, from Developer Options (located under Menu - > Settings) you can (and should) check the USB Debugging feature.

Don’t forget to be precautious – verify how much power is left on your OnePlus 6T before starting to unlock its bootloader. It’s important to do so as if a sudden shut down happens your device might get soft-brickied: in the end you can end up in experiencing software related issues such as boot loops, lags, hangs, screen freeze, battery drain problems, total blackouts and so on. Anyway, try to keep everything secured by plugging in the charger if that’s required – do that especially if the power left is currently lower than 50%.

How to Unlock the OnePlus 6T Bootloader

  1. Start by switching off your OnePlus 6T. Also, wait a few moments while the shut down operation is being completed.

  6. Now, if everything works as explained, in the cmd window execute this command: fastboot oem unlock.
  7. A warning message will be displayed on your OnePlus 6T. Highlight ‘Unlock the bootloader’ by pressing on Volume Up and confirm by pressing on Power button.
  8. Wait while the bootloader is unlocked and in the end reboot your device.
