How to Root and Install Custom Rom in OPPO Find X7 Ultra

 Rooting and installing a custom ROM on a smartphone like the OPPO Find X7 Ultra can unlock new functionalities and enable a personalized experience. However, it's a complex process that can void the warranty, compromise device security, or cause software malfunctions if not done carefully. In this guide, we’ll go over the steps to root your OPPO Find X7 Ultra and install a custom ROM, while discussing the necessary precautions and potential benefits.

What is Rooting?

Rooting is the process of gaining administrative access or "root" privileges on your Android device. This grants you full control over the operating system, allowing you to modify system files, install apps that require root access, remove pre-installed bloatware, and more. However, it also introduces security risks, as malicious apps could exploit root access to compromise your data.

What is a Custom ROM?

A custom ROM is a third-party version of the Android operating system that replaces the stock firmware installed by the manufacturer. Custom ROMs often offer features not available in the original firmware, such as improved performance, enhanced privacy settings, and UI customization. Some popular custom ROMs include LineageOS, Pixel Experience, and Resurrection Remix.

Pre-requisites

Before you start the rooting and custom ROM installation process on your OPPO Find X7 Ultra, you need to prepare and gather the following:

  1. Backup your data: Rooting and installing a custom ROM can wipe all your data, including apps, photos, and files. Ensure you create a full backup before proceeding.

    • Use Google Drive, OPPO’s backup service, or third-party apps like Titanium Backup to backup your data.

  2. Charge your phone: Ensure your phone is at least 70% charged to prevent interruptions during the process.

  3. Unlock Bootloader: The bootloader must be unlocked before you can root the phone or install a custom ROM.

  4. Install ADB and Fastboot: You’ll need these tools to communicate with your phone via your computer.

    • You can install ADB and Fastboot on your PC by downloading them from the official Android Developer page.

  5. Download Custom Recovery: Custom recoveries such as TWRP (Team Win Recovery Project) are essential for flashing custom ROMs and rooting files.

  6. Download Rooting Files: Magisk is the recommended rooting tool for modern devices as it supports systemless rooting (which doesn’t modify system partitions). Download the latest Magisk ZIP file.

  7. Download Custom ROM: Search for a compatible custom ROM for the OPPO Find X7 Ultra. Make sure to download the correct version for your device.

Warning

Rooting and installing custom ROMs voids the warranty and could permanently brick (make unusable) your device. Only proceed if you are comfortable with these risks.

Step 1: Unlock the Bootloader

Unlocking the bootloader allows you to install custom recoveries and root the device. Follow these steps to unlock the bootloader of your OPPO Find X7 Ultra:

  1. Enable Developer Options:

    • Go to Settings > About Phone > tap on Build Number multiple times until you see "You are now a developer."

  2. Enable OEM Unlocking:

    • In Developer Options (Settings > System > Developer Options), turn on OEM Unlocking and USB Debugging.

  3. Install ADB and Fastboot on your computer:

    • Download and install ADB and Fastboot from the official Android SDK platform tools website.

  4. Connect your phone to the computer:

    • Use a USB cable to connect your phone to your computer. Ensure the phone is recognized by your computer using adb devices in the command line.

  5. Reboot to Bootloader:

    • Open the command prompt and type:
      bash
      adb reboot bootloader
    • Your phone will boot into Fastboot mode.

  6. Unlock the Bootloader:

    • In the Fastboot interface, type the following command to unlock the bootloader:
      bash
      fastboot oem unlock
    • This will erase all your data, and you’ll need to confirm on the phone screen by using the volume and power buttons.

After the bootloader is unlocked, your phone will restart and go through a factory reset.

Step 2: Install TWRP Custom Recovery

TWRP is a popular custom recovery that allows you to flash custom ROMs, root your device, and create backups.

  1. Download TWRP for OPPO Find X7 Ultra from the official TWRP website or from trusted developer forums like XDA.

  2. Reboot into Fastboot again by running:

    bash
    adb reboot bootloader

  3. Flash TWRP using Fastboot:

    • Place the downloaded TWRP .img file in the same folder where ADB and Fastboot are installed. Then, use the following command to flash TWRP:
      bash
      fastboot flash recovery twrp.img
    • Replace twrp.img with the actual filename.

  4. Boot into TWRP:

    • Once TWRP is installed, reboot your phone directly into recovery by using this command:
      bash
      fastboot reboot recovery

Step 3: Root Using Magisk

Magisk is the preferred tool for rooting Android devices because it allows for systemless rooting (rooting without altering system partitions).

  1. Transfer the Magisk ZIP to your phone’s internal storage.

  2. Flash Magisk:

    • In TWRP, go to Install > select the Magisk ZIP file > swipe to confirm the installation.

  3. Reboot your device.

After the installation, you can check for root access using root checker apps available on the Play Store.

Step 4: Install Custom ROM

Now that the phone is rooted and a custom recovery is installed, you can install a custom ROM.

  1. Download a compatible ROM for the OPPO Find X7 Ultra, such as LineageOS or any other preferred custom ROM.

  2. Transfer the ROM ZIP file to your phone’s internal storage.

  3. Reboot into TWRP recovery mode by holding the volume up and power buttons simultaneously.

  4. Wipe data and cache:

    • In TWRP, go to Wipe > Advanced Wipe > select Dalvik/ART Cache, System, and Data > swipe to confirm.

  5. Flash the custom ROM:

    • Go to Install > select the ROM ZIP file > swipe to confirm the installation.

  6. (Optional) Flash GApps:

    • If your ROM doesn’t include Google Apps (GApps), download a compatible GApps package and install it the same way you flashed the ROM.

  7. Reboot your phone.

Step 5: Configure and Restore

Once the custom ROM is installed, your phone will boot into the new OS. Set up your device, restore your backups, and enjoy the new features of the custom ROM.

Potential Benefits of Rooting and Custom ROMs

  1. Enhanced Performance: Custom ROMs often offer optimizations that can boost the device’s speed and battery life.

  2. Customization: You can modify the UI, theme, and even system animations to suit your preferences.

  3. New Features: Custom ROMs can include advanced features like gesture controls, privacy enhancements, and deeper control over hardware components.

  4. No Bloatware: Rooting allows you to uninstall unwanted apps that come pre-installed by the manufacturer.

Risks of Rooting and Custom ROMs

  1. Bricking the Device: Improper installation can render the phone unusable (bricked).

  2. Voiding Warranty: Rooting and installing custom ROMs usually voids the warranty provided by the manufacturer.

  3. Security Risks: Rooting disables some of Android’s built-in security measures, leaving your device more vulnerable to malware.

  4. App Incompatibility: Some apps, such as banking apps or DRM-protected services (like Netflix), may not function on rooted devices.

By following this guide carefully, you can successfully root your OPPO Find X7 Ultra and install a custom ROM, unlocking new possibilities for customization and performance enhancement. However, always proceed with caution and ensure you understand the risks before making any modifications to your device.
