Step-by-Step: Install Android 16 on OnePlus Nord 4

1

install_mobile Install TWRP Custom Recovery on OnePlus Nord 4

The first step is to install TWRP (Team Win Recovery Project) custom recovery on your OnePlus Nord 4. 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 Nord 4, skip directly to Step 2.

2

file_copy Transfer the ROM and GApps Files to Your OnePlus Nord 4

Download the Android 16 DerpFest OS ROM zip and your preferred GApps package from the download section above. Connect your OnePlus Nord 4 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.

restart_alt Boot OnePlus Nord 4 into TWRP Recovery Mode

Disconnect the USB cable and power off your OnePlus Nord 4 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.

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 Nord 4 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.

This is the main step. From the TWRP Main Menu, tap Install. Navigate to the folder where you saved the DerpFest OS (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 Nord 4 until it completes. You’ll see “Successful” when done.

This installs the Google Play Store, Gmail, Google Maps, YouTube, and other essential Google services on your OnePlus Nord 4. Without GApps, you won’t have access to Google services or the Play Store.

This clears any residual cached data and ensures a clean, error-free first boot of Android 16 on your OnePlus Nord 4. Skipping this step can cause boot loops or app crashes.

If your OnePlus Nord 4 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”

📱 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 DerpFest OS.

🔙 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 Nord 4 to factory stock condition.

Frequently Asked Questions — Android 16 on OnePlus Nord 4

Here are answers to the most commonly asked questions about installing and using Android 16 (DerpFest OS) on the OnePlus Nord 4:

Is the Android 16 ROM for OnePlus Nord 4 stable enough for daily use?

The DerpFest OS (Android 16) ROM for the OnePlus Nord 4 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 Nord 4 warranty?

Yes, unlocking the bootloader and installing a custom ROM voids the manufacturer warranty. However, since the OnePlus Nord 4 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 Nord 4?

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 Nord 4?

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 Nord 4?

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 Nord 4’s fingerprint scanner?

Yes, in most DerpFest OS builds for the OnePlus Nord 4, 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 Nord 4 after installation?

To update to a newer build of DerpFest OS: 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 Nord 4 for custom ROM installation?

Yes, the Xiaomi Mi CC9 and OnePlus Nord 4 are the same hardware device sold under different names in different regions. The Mi CC9 was the Chinese variant, while the OnePlus Nord 4 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.
