Xiaomi Redmi Pro firmware: official and custom methods

The firmware of the Xiaomi Redmi Pro is a procedure that may be needed to update the system, fix software failures or install custom software. Despite the fact that the model was released in 2016, its current firmware is still supported by enthusiasts and official channels. However, the process has nuances, from unlocking the bootloader to choosing the right version of MIUI or alternative firmware like LineageOS.

Many users face problems after unsuccessful firmware attempts — the device may stop booting or lose connection to the network. To avoid this, it is important to understand three key steps: preparation (data backup, battery charging), method selection (Fastboot, Recovery or EDL) and installation itself. In this article, we will analyze each step with the specifics of Redmi Pro, including solving typical errors like Error: flash write failure or hanging on the Mi logo.

If you’ve never flashed Xiaomi before, start with the official method through the Mi Flash Tool — it’s the safest. Power users can consider custom firmware, but remember: this voids the warranty (if it’s still valid) and requires unlocking the bootloader through your Mi Account.

1. Firmware Preparation: What to Do Before Starting

The first step is to save all data. The firmware, especially through Fastboot, erases the device's internal memory. Use Settings → Additional → Backup or third-party utilities like Titanium Backup (requires root). Be sure to copy photos, contacts and SMS to your PC or cloud.

Then check the battery charge, it should be at least 60%. With a low charge, the device can turn off during firmware, which will lead to a breeze (impossibility to turn on without service equipment).

• 🔌 Cable USB Type-C (original or high-quality – cheap cables can interrupt data transmission).
• 💻 Computer on Windows 7/10/11 (The Mi Flash Tool is required for Windows).
• 📥 Firmware for your model (download from the official Xiaomi website or trusted forums like this one) XDA Developers).
• 🔑 Mi Account with a linked phone number (to unlock the bootloader).

Attention to the firmware version! Redmi Pro has several modifications:

• 📱 omega - global version (MIUI Global).
• 📱 omega_cn — Chinese version (requires Russification).

Install firmware from another modification is impossible – this will lead to an anti-rollback error (impossibility of rollback on the old version).

⚠️ Note: If your Redmi Pro was purchased in China, check for Google services support. Chinese firmware does not include them - you will need a separate installation of GApps.

2 Unlocking the bootloader: a mandatory step for firmware

By default, Xiaomi bootloader is locked. To flash the device through Fastboot or install custom software, it needs to be unlocked.The process takes up to 720 hours (30 days) due to Mi's security policy.

Instructions for unlocking:

5. Sign in to your Mi Account and follow the instructions. If you have a waiting message, wait. SMS-notification (usually 3-7 days).

Important: Once the bootloader is unlocked, all data, including photos in internal memory, will be reset, and some functions (such as Mi Pay) may stop working.

3. Firmware techniques: Fastboot vs Recovery

There are two main ways to use Redmi Pro:

For most users, Fastboot is optimal as it guarantees a clean installation.Recovery is suitable for airborne updates (OTA) or if you are confident in the integrity of the current system.
