Installing TWRP recovery on the Oneplus 7 pro on Android 10(Q):

• Step 1: make sure "USB degubing" and "OEM unlocking"( bootloader unlocking) is enabled on your phone and it is charged above at least 50%.

• Step 2: connect your phone on a computer and transfer the zip file included on phone storage:

PS: the zip referred is "twrp-3.3.1-74-guacamole-unified-installer-mauronofrio.zip" and all the zips you want to install after like the latest versions of "Magisk,Youtube vanced, etc".

• Step 3: putting your phone in bootloader mode(fastboot mode).
  • doing it manuary by pressing a combination of power button or vol buttons
  • Suggested method: adb installed
    • connected your phone on a computer and type in the terminal(in the PATH of adb files):

    //to be sure that the computer can detect your phone correctly (you should see its id_num displayed)
      $ adb devices
    //should reboot the device in fastboot mode in few seconds.
      $ adb reboot bootloader

• Step 4: while phone is fastboot mode
  • test:

    //to make sure it is discovered correctly.
      $ fastboot devices

  • booting twrp(not installing):

      $ fastboot boot twrp-3.3.1-74-guacamole-unified-Q-mauronofrio.img

wait for the device to boot into "twrp recorvery" (around 10s)

• Step 5:
  • tap on "install" and select the zip file "twrp-3.3.1-74-guacamole-unified-installer-mauronofrio.zip" and reboot after the installation is completed.
  • reboot into recovery again(twrp should be default this time) and install "Magisk___.zip"

Now TWRP is fully installed and your device is rooted

After this you can flash all the other files you need.
