Seeing as how the OnePlus 6T kernel sources were made available on the same day of the device’s release, it was no time at all before this device was rooted. The only caveat is that the T-Mobile edition of the OnePlus 6T comes with a locked bootloader, which cannot be unlocked until it is fully paid off. All other variants of the OnePlus 6T can easily have their bootloader unlocked, however. If you are a happy new owner of the latest OnePlus 6T device, and want to unlock the OnePlus 6T bootloader and root it, read our comprehensive guide. Be warned, however, that the procedure will wipe your phone and factory reset it – so creating a backup of your important data is absolutely recommended.
Requirements
A note on T-Mobile OnePlus 6T Variant
If you purchased your OnePlus 6T through T-Mobile, you cannot unlock the bootloader until you have fully paid off the device according to your plan, and you have used it on the T-Mobile network for a period of forty days. After these prerequisites are satisfied, you need to unlock your bootloader through OnePlus online form. You will typically fill out the form and provide OnePlus / T-Mobile with your IMEI number. You obtain this by dialing *#06# in your phone dialer, and it will display your IMEI code – copy this down. Once you have your unlock code from OnePlus / T-Mobile, you reboot into fastboot mode (or use the ADB command ‘adb reboot bootloader’). In ADB you then type: fastboot oem get_unlock_code This will return a long token key, which you will provide to another form from T-Mobile, and they will email you a file that you can flash on your OnePlus 6T to fully unlock the bootloader. You should receive the file to your email within a couple of weeks. You place the file from T-Mobile inside your ADB path, and type the ADB command: fastboot flash cust-unlock <unlock_token.bin> Then you just unlock your bootloader the normal method, as we showed you earlier in this guide (ADB command ‘fastboot oem unlock’). Then you can proceed to root your OnePlus 6T using the TWRP / Magisk method we also showed earlier. More information can be found on the official OnePlus page for unlocking the T-Mobile variant.
