How to Root the Blackview BV9000 Pro-F

Blackview is a rising star in the Chinese smartphone market, establishing a reputation for their rugged-style devices. The Blackview BV9000 Pro-F is one such device, with a 5.7” inch screen at 1080×2160 display resolution, the Mediatek MT6757 chipset which is common in most Chinese phones, and an actually impressive 6GB of RAM and 128GB of storage.

Rooting the Blackview BV9000 Pro-F is, surprisingly, not the easiest task. As a Mediatek-based device, we can’t simply flash TWRP and SuperSU or Magisk, we’ll need to use MediaTek SP Flash tool and do a few things first. Follow our guide closely, and you’ll be able to root your Blackview BV9000 Pro-F in no time.

Warning: We will be unlocking your phone’s bootloader during this process. Backup any of your important files and personal data, as unlocking the bootloader will perform a factory reset on your device!

Requirements:

1. First we need to unlock your bootloader. Go to Settings > About > tap ‘Build Number’ 7 times until Developer Mode is activated.
2. Now go to Settings > Developer Options > enable Unlock OEM and also enable USB Debugging.
3. Connect your Blackview phone to your PC via USB cable, go to your main ADB installation folder on your PC, hold Shift + right click and choose “Open a Command Window Here”.
   
4. Now in the ADB window, type: adb devices
5. You may need to accept an ADB pairing dialogue on your Blackview’s screen – but once the connection is established, typing ‘adb devices’ into the ADB terminal should return your device’s serial number.
6. If the ADB connection is not recognized, you may need to troubleshoot your ADB installation, USB connection, or USB drivers.
7. If the ADB connection was recognized, proceed to type into the ADB window: adb reboot bootloader
8. Your Blackview phone should reboot into Fastboot Mode, so from there, type into ADB window: fastboot oem unlock
9. This will proceed to unlock the bootloader and factory reset your device. When its done, you should be taken back to the Android system.

Preparing for the Root

1. After you’ve unlocked the bootloader, you’ll need to setup your phone again. You should take this time to install any available updates, because once your phone is rooted, you cannot receive official OTA firmware updates. Attempting to install or flash OTA updates with a rooted device will lead to recovery boot loops.
2. Download and install the SP Flash tools onto your PC, and also the MediaTek VCOM Drivers.
3. You may need to disable driver signature enforcement policy in Windows when installing the MediaTek VCOM drivers. The steps for that are given in this similar Appual’s root guide, “How to Root the Lenovo Vibe S1”.

Rooting the Blackview BV9000 Pro-F

1. Download the Magisk .zip and copy it to your phone’s SD card.
2. Now launch the SP Flash Tool, and extract the ROM archive. In the SP Flash tool, load the scatter file which is located in the ROM’s “R06” folder.
3. Choose “Download Only” option in SP Flash tool, or else it will format and remove your IMEI which will render your phone totally useless.
   
   
4. Uncheck everything but Recovery, because we are only flashing this file.
5. Press the “Download” button.
6. Now hold Volume Up + Power on your Blackview phone, keeping the Volume Up button held down.
7. The flash should complete quickly, with a green checkmark to verify its success.
   
8. When that’s done, remove the USB cable from your PC, and connect your Blackview phone to a USB mouse using an OTG cable.
9. Now hold Power + Volume Up until it boots to Bootloader Mode, and use the menu to choose “Recovery”.
10. This should launch you into TWRP recovery – touchscreen is disabled for this TWRP version, which is why we’re using the OTG mouse.
11. Click “Cancel” to deny decrypting user data storage, this is unnecessary for us.
12. Go to Install > SD Card > choose the Magisk.zip, and swipe to flash it. Allow it to install any apps as /System apps! We want this because it will install to the /system image, instead of /userdata.
13. Reboot your device, and you should see Magisk Manager listed in your phone apps – use that to verify the root was successful.
