Here’s how to install TWRP recovery on OnePlus 8 or 8 Pro! You can install TWRP recovery if you want to install a custom ROM.
Step 1. You will need to unlock the bootloader first, follow my universal guide here:
Note: If you are using a carrier-branded OnePlus 8 or 8 Pro such as T-Mobile or Verizon, you will have to unlock the bootloader by getting unlocked code from your carrier, you can search on Google on how to do this. But next time, simply buy the unlocked model as it supports full 4G LTE/5G bands on T-Mobile or Verizon, you don’t gain ANYTHING by buying T-Mobile/Verizon models, you actually lose dual SIM capability and another process to unlock the bootloader.
You just need to unlock the bootloader, you do NOT need to follow the root guide as we are simply installing a custom ROM.
Step 2. You will need to flash TWRP recovery.
Unzip fastboot.zip and you should find a new folder called “fastboot”.
Step 3. Download TWRP and userdata image for OnePlus 8 & 8 Pro:
