How to Unlock Bootloader on OnePlus 7 Pro (T-Mobile and Unlocked)

For users looking to modify their OnePlus 7 Pro or want to flash firmwares manually, here is how to unlock bootloader on the phone.

Our guide ahead lists down the complete, official unlock process that you can implement on your OnePlus 7 Pro. Further, this guide works with standard 7 Pro as well as devices bought through T-Mobile.

Rather than shipping phones that already have unlocked bootloaders, OnePlus ships them as locked.

Backup and Other Important Tips

Please take a look at the following tips and important points you need to take care of. These are important, as we don’t want anyone losing their personal data or apps.

Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. Read: How to Backup Android Apps, Text Messages, WhatsApp, Call History.

If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up. [Tutorial: How to Backup Android Phone using TWRP]

A few more optional tips that you should remember:

1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean and KitKat.

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?

3. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend not to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.

4. [IMPORTANT] Copy all the backup files from your SD card to your computer as internal memory will be wiped clean while unlocking the bootloader.

If you are a developer and would want to unlock the bootloader, we recommend doing that before you set up the Google Play Store, install apps or anything because the security feature in Android clears out everything from your phone when unlocking bootloader of a phone.

You can now install a custom recovery, a custom ROM or any system tweak you like. Just be careful with what you do! 😉
