Step-by-Step: Install Android 15 on Poco X6

1

install_mobile Install TWRP Custom Recovery on Poco X6

The first step is to install TWRP (Team Win Recovery Project) custom recovery on your Poco X6. 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 Poco X6, skip directly to Step 2.

2

file_copy Transfer the ROM and GApps Files to Your Poco X6

Download the Android 15 Evolution X ROM ROM zip and your preferred GApps package from the download section above. Connect your Poco X6 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 Poco X6 into TWRP Recovery Mode

Disconnect the USB cable and power off your Poco X6 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 15 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 Poco X6 for the Android 15 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 15 ROM.

This is the main step. From the TWRP Main Menu, tap Install. Navigate to the folder where you saved the Evolution X ROM (Android 15) 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 Poco X6 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 Poco X6. Without GApps, you won’t have access to Google services or the Play Store.

cached Wipe Cache and Dalvik Cache

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 15 on your Poco X6. Skipping this step can cause boot loops or app crashes.

Troubleshooting Common Issues

🔄 Stuck on Boot Animation (Bootloop)

If your Poco X6 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 15 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 Poco X6. Also ensure your TWRP version is up-to-date and compatible with Android 15 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 Evolution X ROM.

🔙 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 Poco X6 to factory stock condition.

Frequently Asked Questions — Android 15 on Poco X6

Here are answers to the most commonly asked questions about installing and using Android 15 (Evolution X ROM) on the Poco X6:

Is the Android 15 ROM for Poco X6 stable enough for daily use?

The Evolution X ROM (Android 15) ROM for the Poco X6 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 Poco X6 warranty?

Yes, unlocking the bootloader and installing a custom ROM voids the manufacturer warranty. However, since the Poco X6 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 15 on my Poco X6?

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 15 on Poco X6?

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 15 (API 35). Read our complete GApps compatibility guide to choose the best option for your needs.

Do I need an unlocked bootloader to install Android 15 on Poco X6?

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 15 ROM support the Poco X6’s fingerprint scanner?

Yes, in most Evolution X ROM builds for the Poco X6, 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 15 ROM on my Poco X6 after installation?

To update to a newer build of Evolution X ROM: 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 Poco X6 for custom ROM installation?

Yes, the Xiaomi Mi CC9 and Poco X6 are the same hardware device sold under different names in different regions. The Mi CC9 was the Chinese variant, while the Poco X6 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.
