Xiaomi Redmi 4 (prada) Firmware Flash File Download [Stock ROM]
Xiaomi Redmi 4 (codename prada) was a standout device in the budget segment, offering a premium metal unibody design, capable Snapdragon 430 performance, and a large 4100mAh battery. If your device is experiencing bootloops, fingerprint sensor failures, or rapid battery drain, flashing the correct stock firmware is the most reliable fix. This page provides official fastboot ROMs for both Chinese and Global variants, a debloated Xiaomi.eu ROM, and the official TWRP recovery for the MSM8937 platform.
Important Note: The Redmi 4 (prada) is part of the ‘mi8937’ device family, which also includes the Redmi 4X (santoni) and Redmi 5A (riva). While they share a chipset, their firmware is not interchangeable. Flashing santoni or riva firmware on prada will hard brick your device. Always confirm your codename is prada.

How to Flash via Fastboot (Mi Flash Tool)
- Unlock your bootloader using the official Mi Unlock tool. This is a mandatory first step.
- Extract the downloaded .tgz firmware file to a folder on your PC.
- Open Mi Flash Tool. Click Select and choose the extracted ROM folder.
- With your phone powered off, boot into Fastboot mode (Hold Volume Down + Power). Connect it to the PC.
- In Mi Flash Tool, choose the clean all option. Avoid “clean all and lock” unless you are absolutely certain you are flashing the correct stock ROM for your device’s original region.
- Click Flash and wait for the process to complete. The first boot may take 5-10 minutes.
FAQs
Q1. My fingerprint sensor stopped working after a software update. Can I fix it?
Yes, this is a common software glitch on the Redmi 4. A clean flash of the stock ROM using the “clean all” option in Mi Flash Tool will reinstall all hardware drivers and firmware, which almost always restores fingerprint functionality. If it persists after a clean flash, the sensor itself may be faulty.
Q2. What is the difference between Redmi 4 (prada) and Redmi 4X (santoni)?
While they share the same Snapdragon 430 chipset, they are different devices:
- Redmi 4 (prada): Metal unibody, 5″ 720p display, fingerprint sensor.
- Redmi 4X (santoni): Plastic body, 5″ 720p display, no fingerprint sensor.
Their firmware is not compatible. Flashing santoni ROM on prada will brick your device.
Q3. Can I upgrade to a newer Android version on my Redmi 4?
Officially, no. The device stopped at Android 6.0. However, the active custom ROM community has developed builds of LineageOS 14.1 (Android 7.1) and even newer versions. These can give your device a performance boost and newer features, though you may need to troubleshoot minor hardware compatibility issues.
Q4. Why is my battery draining faster than usual even after a fresh flash?
While software can cause drain, the Redmi 4 is now quite old. The most likely cause is that the battery itself has degraded and can no longer hold its original capacity. After ensuring no apps are causing wake locks post-flash, consider replacing the battery for a hardware solution.
Troubleshooting (Prada-Specific)
- “Antirollback check error” in Mi Flash Tool: The Redmi 4 has Anti-Rollback (ARB) protection. This error means you’re attempting to flash a ROM with an older security patch level. You must flash a ROM with the same or a higher version number. Check your current ARB version with
fastboot getvar antibefore flashing. - Fingerprint sensor not detected in settings: This is usually a software/driver issue fixed by a clean flash. If it persists, test the hardware by booting into MIUI’s hardware test mode (
*#*#6484#*#*) and running the fingerprint test. - Device not charging or charging slowly: This is often a hardware issue with the USB charging port, which is a common wear point. Try a different cable and charger first. If problem persists, the port may need cleaning or replacement.
- Wi-Fi or Bluetooth turning on: This can occasionally be caused by a corrupted
persistpartition. Flashing the stock ROM usually restores this partition. If not, the issue may be a failing Wi-Fi/BT chip, which is a known hardware fault on aging devices. - Flashing TWRP but it doesn’t stick: After flashing TWRP via fastboot (
fastboot flash recovery twrp.img), immediately boot into it withfastboot boot twrp.img. Once in TWRP, go to **Settings** and check **”Keep Read Only”** to prevent the stock ROM from overwriting recovery on reboot.
