Update Xiaomi Redmi Note 9 Pro: 3 proven ways + error solving

Xiaomi Redmi Note 9 Pro remains one of the most popular smartphones even years after its release – thanks to the powerful Snapdragon 720G processor, long battery life and regular updates to MIUI. However, many users face problems when trying to update the firmware, from the hanging boot process to errors like Couldn’t verify update or Error 7. In this article, current ways to update for 2026, including official and alternative methods, as well as solving typical bugs.

It’s important to understand that Redmi Note 9 Pro (codename joyeuse) supports upgrades to MIUI 14 based on Android 12, but further updates from Xiaomi are unlikely.This means that new versions of Android (13+) will require custom firmware — but we’ll talk about this separately.

1.Renewal Preparation: What to Do Before You Start

Before you click Update, follow a few critical steps, and neglecting them can lead to data loss, system failure, or even a smartphone failure.

• 🔋 Battery charge - at least 60%. Optimally — 80-100%. With a low charge, the smartphone can turn off during the update, which is fraught with partition damage. /system.
• 📡 Stable Internet connection. To load firmware with weight 2-3 Avoid mobile internet – use Wi-Fi at speeds from 10 Mbit/s.
• 📱 Backup: Save contacts, photos and apps through Settings → Google → Backup or manually on PC.
• 🔧 Free space. Internal storage should have at least 5GB free — temporary update files take up a lot of space.

Pay special attention to the current firmware version. To find out, go to Settings → About Phone → MIUI version. If your version is older than MIUI 12.5, you will have to update in stages - you can not immediately switch to MIUI 14.

⚠️ Note: If your Redmi Note 9 Pro is unlocked (installed) TWRP or custom Recovery, an official update through settings can result in a logo getting stuck MI. In this case, use the methods via Fastboot or Recovery (sections 3 and 4).

2. Method 1: Update through settings (the easiest method)

This is the official and recommended way Xiaomi can use, and it's suitable for 90% of users, and it doesn't require a computer and it stores all the data, but it only works if:

• 📲 The smartphone is not rooted and does not have custom Recovery.
• 🔄 Current firmware - official MIUI (European, Chinese or European).
• 🌍 The firmware region coincides with the region of the device (for example, EEA Europe).

Instructions:

1. Open Settings → About the phone → System update.
2. Click on the three dots in the top right corner and select Update Package (if the update is already downloaded) or Download the latest version.
3. Wait for the updates to be checked. If it's available, click Download.
4. After downloading, tap Reboot and update.

This method will be useful if:

• 🔄 Update via settings gives an error Couldn't verify update.

6. Alternative firmware: should we switch to custom?

Official updates for the Redmi Note 9 Pro have been discontinued, but enthusiasts continue to release custom firmware based on Android 13/14.

• 📱 LineageOS – pure Android without unnecessary applications.
• 🔄 Pixel Experience – firmware with the corporate interface Google Pixel.
• 🔧 ArrowOS – Balance between productivity and customization.
• 🎯 MIUI EU — modified MIUI without Chinese services.

Advantages of custom firmware:

• ✅ Newer versions of Android (up to 14).
• ✅ Lack of advertising and unnecessary applications.
• ✅ Improved productivity and battery life.

Disadvantages:

• ❌ Loss of warranty (if it is still valid).
• ❌ Risk of "bricking" if installed incorrectly.
• ❌ Possible bugs with camera, sensors or mobile network.

If you decide to use custom firmware, follow the instructions on the XDA Developers or 4PDA forums. Be sure to unlock the bootloader and install TWRP Recovery before you run the firmware.

7 How to roll back an update if something goes wrong

If after the update, the smartphone began to work worse (heats, quickly sits down, brakes), you can return the previous version of MIUI.

1. Download the old firmware from the Xiaomi website (choose the version on 1-2 issues back).
2. Move the.zip file to the root of the internal memory.
3. Enter the Recovery (Food + Volume Up).
4. Select Install update.zip to System and confirm the rollback.

Important: rollbacks are only possible within one major Android version, for example, with MIUI 14 (Android 12) you can return to MIUI 13 (Android 12), but not to MIUI 12.5 (Android 11) - this will lead to an Error 7 error.

⚠️ Note: When rolling back on the old firmware, a complete data reset (Wipe Data in Recovery) may be required, otherwise the system will be unstable.
