Q1. What is the difference between "A", "C", and "F" builds?

The build letters signify the major Android version: "A" builds are Android 10 (Realme UI 1.0), "C" builds are Android 11 (Realme UI 2.0), and "F" builds are Android 12 (Realme UI 3.0). Use this to choose the correct firmware for downgrading.

Q2. Can I use this to fix a "hard bricked" Realme X50 Pro?

Yes. As long as your PC can detect the phone in EDL Mode (as "Qualcomm HS-USB QDLoader 9008"), the flash tool can rewrite the entire system and bring your phone back to life.

Q3. I'm experiencing severe battery drain after the Android 12 update. What should I do?

This is a common reason for downgrading. You can use one of the "C" build firmwares from this page to flash your device back to the more stable Android 11, which often resolves battery drain issues introduced in newer updates.

Realme X50 Pro 5G Stock ROM (Firmware) | Unbrick, Downgrade & Restore

The Realme X50 Pro 5G (RMX2081) is a flagship smartphone from 2020, powered by the high-performance Qualcomm Snapdragon 865 chipset and featuring a 90Hz Super AMOLED display with 65W SuperDart charging. The device launched with Android 10 and has since received updates to Android 11 and Android 12. However, major OS updates can sometimes introduce bugs, reduce battery life, or include UI changes that users dislike. This guide provides a comprehensive collection of official firmware packages for Android 12, 11, and 10, allowing users to unbrick a dead phone, downgrade from a problematic update, or perform a clean installation to resolve any software issue.

⚠️ CRUCIAL WARNING: Unbrick Tool & Downgrade Risk
This process uses the official Realme Flash Tool, a powerful low-level utility. It is the standard method for unbricking a Qualcomm-based Realme phone. This will completely erase all your personal data and will re-lock the bootloader. Downgrading major Android versions (e.g., from 12 to 11) carries inherent risks. Proceed with extreme caution.

Backup Your Data: This process will wipe all data. Back up everything if your phone is accessible.
Charge The Battery: Ensure your phone has at least a 60% charge. If the phone is bricked, charge it for an hour before starting.
Windows PC: You need a Windows PC and the original Realme USB-A to USB-C cable.

🔧 Device Troubleshooting

The flash tool is not detecting my phone: This is a driver issue. Ensure you have correctly installed the Qualcomm HS-USB QDLoader drivers, potentially disabling “Driver Signature Enforcement” in Windows. Verify the phone is in EDL mode and connected securely.
After flashing, the phone is stuck on the Realme logo: The first boot after a full flash or downgrade can take a very long time (up to 20 minutes). If it’s still stuck, you may need to force the phone into recovery mode and perform a “Wipe data/factory reset”.
