error

Device-specific ROM: This Android 16 custom ROM is ONLY for the OnePlus 7 Pro. Do not flash it on any other device — it will brick your device.

Step-by-Step: Install Android 16 on OnePlus 7 Pro

1

install_mobile Install TWRP Custom Recovery on OnePlus 7 Pro

The first step is to install TWRP (Team Win Recovery Project) custom recovery on your OnePlus 7 Pro. TWRP replaces the stock recovery and allows you to flash custom ROMs, GApps, and create complete system backups. You’ll need a PC/Mac with ADB and Fastboot tools installed, plus a USB cable. If TWRP is already installed on your OnePlus 7 Pro, skip directly to Step 2.

2

file_copy Transfer the ROM and GApps Files to Your OnePlus 7 Pro

Download the Android 16 LineageOS 23 ROM zip and your preferred GApps package from the download section above. Connect your OnePlus 7 Pro to your computer via USB and transfer both .zip files to the device’s internal storage root folder or SD Card. Remember the file location — you’ll need to find these files in TWRP later.

3

restart_alt Boot OnePlus 7 Pro into TWRP Recovery Mode

Disconnect the USB cable and power off your OnePlus 7 Pro completely. Once the device is off, press and hold the Power button + Volume Up button simultaneously until you see the TWRP logo appear on screen. Release both buttons when TWRP loads. If prompted, swipe to allow modifications.

4

backup Create a Nandroid Backup of Your Current ROM

This step is critical for safety. In TWRP, tap Backup and create a complete Nandroid Backup. This creates a bit-for-bit copy of your entire current system — including the ROM, apps, data, and settings. If anything goes wrong during the Android 16 installation, or if you want to return to your previous ROM, you can restore this backup in minutes.

delete_sweep Perform a Factory Reset Using Advanced Wipe

Now perform a thorough Factory Reset to prepare your OnePlus 7 Pro for the Android 16 ROM. In TWRP, navigate to Wipe → Advanced Wipe. Check the boxes for Cache, Dalvik Cache, System, and Data partitions. Then Swipe to Wipe. This completely clears the old system files, user data, and cache — preventing conflicts with the new Android 16 ROM.

After the wipe completes successfully, navigate back to the TWRP Main Menu by tapping the back arrow or pressing the home/center navigation button on your OnePlus 7 Pro. You should see the main TWRP screen with options like Install, Wipe, Backup, Restore, etc.

This is the main step. From the TWRP Main Menu, tap Install. Navigate to the folder where you saved the LineageOS 23 (Android 16) ROM zip file. Tap the file to select it, then Swipe to Confirm Flash. The flashing process takes 2–5 minutes — do not touch anything or power off your OnePlus 7 Pro until it completes. You’ll see “Successful” when done.

apps Flash the Google Apps (GApps) Package

Immediately after the ROM flash completes, do not reboot yet. Instead, tap “Install” again (or use the back button), navigate to your GApps zip file, and flash it the same way. This installs the Google Play Store, Gmail, Google Maps, YouTube, and other essential Google services on your OnePlus 7 Pro. Without GApps, you won’t have access to Google services or the Play Store.

After the GApps flash completes, you’ll see a “Wipe cache/dalvik” button at the bottom left of the TWRP screen. Tap it and Swipe to Wipe. This clears any residual cached data and ensures a clean, error-free first boot of Android 16 on your OnePlus 7 Pro. Skipping this step can cause boot loops or app crashes.

Troubleshooting Common Issues

🔄 Stuck on Boot Animation (Bootloop)

If your OnePlus 7 Pro is stuck on the boot animation for more than 15 minutes, it may be bootlooping. Reboot into TWRP (Power + Vol Up), perform a full wipe (System, Data, Cache, Dalvik), and re-flash the ROM and GApps. Make sure you’re using compatible GApps for Android 16 arm64.

❌ “Error 7” or “Zip Verification Failed”

This usually means you’re flashing a ROM not built for your device. Double-check that the ROM zip is specifically for the OnePlus 7 Pro. Also ensure your TWRP version is up-to-date and compatible with Android 16 ROMs.

📱 No Mobile Data or Signal After Installation

You may need to flash the correct firmware (baseband/modem) before installing the ROM. Check the XDA Forum thread for the recommended firmware version for your build of LineageOS 23.

🔙 How to Restore Back to Stock ROM

If you want to go back to the stock ROM: (1) restore your Nandroid Backup via TWRP → Restore, or (2) download the official stock ROM from the manufacturer and flash it using the appropriate flash tool on your PC. This will completely restore your OnePlus 7 Pro to factory stock condition.

Frequently Asked Questions — Android 16 on OnePlus 7 Pro

Here are answers to the most commonly asked questions about installing and using Android 16 (LineageOS 23) on the OnePlus 7 Pro:

Is the Android 16 ROM for OnePlus 7 Pro stable enough for daily use?

The LineageOS 23 (Android 16) ROM for the OnePlus 7 Pro is an unofficial build. Core features — including phone calls, Wi-Fi, mobile data, camera, Bluetooth, GPS, and the fingerprint scanner — work well in most builds. Some minor bugs may exist depending on the build version. We recommend checking the XDA Forum thread for the latest known issues before installing it as your daily driver.

Will installing a custom ROM void my OnePlus 7 Pro warranty?

Yes, unlocking the bootloader and installing a custom ROM voids the manufacturer warranty. However, since the OnePlus 7 Pro was released in September 2019, virtually all units are well past their warranty period, so this shouldn’t be a concern for most users.

Can I go back to stock ROM after installing Android 16 on my OnePlus 7 Pro?

Absolutely. You have two options: (1) Restore your Nandroid Backup through TWRP Recovery to return to your exact previous ROM state, or (2) Download the official stock ROM from the manufacturer’s website and flash it using the appropriate flash tool to perform a clean restore to stock firmware.

Which GApps package should I use with Android 16 on OnePlus 7 Pro?

You can choose from four popular options: LiteGApps (recommended for minimal footprint), NikGApps (offers granular control over which Google apps to install), MindTheGApps (balanced package), or BiTGapps (lightweight alternative). All must be the ARM64 variant for Android 16 (API 36). Read our complete GApps compatibility guide to choose the best option for your needs.

Do I need an unlocked bootloader to install Android 16 on OnePlus 7 Pro?

Yes, an unlocked bootloader is a mandatory prerequisite. Without it, you cannot install TWRP Recovery or flash any custom ROM. Use the manufacturer’s official unlock tool to request a bootloader unlock. The process typically involves a waiting period before the unlock is approved.

Does the Android 16 ROM support the OnePlus 7 Pro’s fingerprint scanner?

Yes, in most LineageOS 23 builds for the OnePlus 7 Pro, the fingerprint scanner works correctly. However, functionality can occasionally vary between different build versions. If the fingerprint scanner isn’t working after installation, try updating to the latest build or check the XDA Forum for any required patches.

How do I update the Android 16 ROM on my OnePlus 7 Pro after installation?

To update to a newer build of LineageOS 23: Download the latest ROM zip from the LineageOS download page, transfer it to your device, reboot into TWRP, and flash the new ROM zip over the existing installation (this is called a “dirty flash”). Then wipe cache/dalvik and reboot. A full data wipe is usually not needed for minor updates, but always check the XDA thread for update-specific instructions.

Is the Xiaomi Mi CC9 the same as the OnePlus 7 Pro for custom ROM installation?

Yes, the Xiaomi Mi CC9 and OnePlus 7 Pro are the same hardware device sold under different names in different regions. The Mi CC9 was the Chinese variant, while the OnePlus 7 Pro was the global/international variant. Both use the exact same ROM, TWRP recovery, firmware, and kernel files. You can follow this same guide for either device.
