Rolling back an Android update on Realme: 3 proven ways to return the old firmware

Android updates on smartphones Realme often bring new features, security fixes, and performance optimizations. However, users often encounter the other side of the coin: after an upgrade, the device begins to slow down, discharges faster, or completely stops working correctly. If you find yourself in a similar situation, don’t despair. Rolling back an update to Realme is quite possible, but the process requires care and adherence to key rules.

In this article we will look at three officially supported methods of firmware rollback: through Recovery Mode, using Fastboot and through proprietary software Realme Flash Tool. You will also learn how to avoid mistakes, save important data, and what to do if your smartphone stops turning on after an unsuccessful rollback. Important: the procedure may differ depending on the model (Realme GT Neo 3, Realme 9 Pro+, Realme C55 etc.), so always check the official documentation of your device.

Before you begin, answer two questions: why do you want to roll back? (bugs, lags, loss functionality?) and Which firmware version do you consider? stable. This will help you choose the right method and avoid repeated problems. For example, if after upgrading to Realme UI 4.0 on Realme 10 Pro root access is lost, rolling back to Realme UI 3.0 can return it, but will require unlocking the bootloader.

1. Preparing for a rollback: backup, charging and checking the model

The first and most important step is saving all critical data. Firmware rollback is almost always accompanied by a reset to factory settings, so without a backup you risk losing:

• 📱 Contacts, SMS and call log (if not synchronized with Google Account)
• 📷 Photos and videos in internal memory (external card microSD usually not affected)
• 🎮 Game saves (especially if they are not linked to the cloud)
• 📄 Documents and files in folders Download, Documents i etc.

For backup, use:

• 🔄 Google Drive (for contacts, calendar, some settings)
• 💾 Realme Cloud (branded cloud from the manufacturer)
• 📱 Third-party utilities like Titanium Backup (requires root) or Swift Backup
• 🖥️ Manual copying to PC via MTP (Windows/macOS Explorer)

Also required:

1. Charge your smartphone at least to 60% (preferably up to 80-100%). Interruption of the process due to low battery can lead to "briku" (inoperable state of the device).
2. Check the exact model of your Realme in the settings: go to Settings → About phone → Model. For example, RMX3363 is Realme 9 Pro+ 5G.
3. Find the current firmware number in Settings → About phone → Software version. It looks like RMX3363_11_A.15 or similar.

⚠️ Attention: If your Realme is unlocked via OEM Unlock or has root access, rolling back the firmware may lead to the bootloader being locked (bootloader). In this case, you will need to unlock again, which resets all data.

2. Where to download the official firmware for Realme

Using unofficial or modified firmware is fraught with loss of warranty, unstable operation and even failure of the device. Therefore, download files ONLY from official sources:
