Owners of the legendary Xiaomi Redmi Note 3 Pro, known under the code name kenzo, often face a dilemma: whether to switch from the usual Android 5.1.1 to a more modern version of 7.0 Nougat. This smartphone was released in 2016 and became a hit thanks to the metal body and powerful at the time processor Qualcomm Snapdragon 650. However, time is inexorable, and many modern applications require a fresher operating system for stable operation.
The upgrade process is not trivial, as official support for the device by Xiaomi has long been discontinued.However, there is a proven path to transition to the official global firmware Android 7.0, which provides better power optimization and support for new security standards. It is important to understand that any manipulation of system software carries certain risks, so preparation must be careful.
In this article, we will take a look at all the transition steps, from checking the current version to final configuration, how to avoid errors that can turn a device into a brick, and what tools you will need to successfully complete the procedure. Experimentation is good, but having a backup is a must.
Risk assessment and device preparation
Before you start any action, you need to understand that updating your firmware is a process of overwriting system partitions. For Redmi Note 3 Pro, switching from MIUI 8 based on Android 5.1 to MIUI 9 or 10 based on Android 7.0 requires a strict sequence of actions. Ignoring the preparatory steps can lead to loss of personal data or software failures.
Make sure the battery is at least 60% battery power. The installation process can take 15 to 40 minutes, and a sudden power outage at a critical time of recording flash memory can disrupt the bootloader. Also free up space in internal memory: a minimum of 4-5 GB of free space will be required to load the firmware archive and temporarily place it.
⚠️ Warning: Before starting the procedure, be sure to back up all important contacts, photos and documents. When you update with a complete cleanup (Clean Install), all data will be irretrievably deleted.
Check integrity USB-The cable that you plan to use to connect your smartphone to your computer if you need manual installation. Cheap cables often don't provide a stable connection, which can interrupt file transfer. Use the original cable or high-quality analogue with thick wires inside.
☑️ Firmware readiness
The next step is to determine the current version of MIUI. To do this, go to Settings → About Phone. If you have a Chinese version (CN), the process may be different from updating the global (Global) version. In most cases, Redmi Note 3 Pro is recommended to upgrade to a global stable version to avoid localization issues and lack of Google services.
Selecting the Upgrade Method: OTA or Manual Mode
There are two main ways to install updates on Xiaomi devices: automatic via OTA (Over-The-Air) and manual through the Recovery menu. Automated method is convenient when the company’s servers are still distributing update packages for a particular model, but for older devices like kenzo, this channel is often closed or offers only minor security edits.
Manually, the method involves downloading the firmware archive with the.zip extension and installing it through the system recovery menu, which gives you complete control over the process and allows you to “jump” over several versions of MIUI, which is especially important for the transition to Android 7.0.
For manual installation, you will need to download the current firmware file. The official archives can be found on specialized resources or the 4PDA forum, where enthusiasts store copies of official builds. Look for a file marked Stable, not Developer, since stable versions are more thoroughly tested.
After downloading the file, do not unpack it. The archive must remain in the root internal memory or on the microSD card so that the system can correctly identify it, miui_KENZOGlobal_V10.X.X.X....
Step-by-step: installation through Recovery
This is the most common and safe method for users who do not want to use complex tools such as: ADB. The whole process takes place inside the smartphone interface. First, place the downloaded one. ZIP-archive to the root of internal memory. Then go to the Settings menu → The phone. → Version. MIUI.
Click on the three-dot menu in the upper right corner of the screen and select Select a firmware file. The system will open the file manager where you need to find the previously downloaded archive. After selecting the file, the phone will prompt you to confirm the reboot to start the installation.
Sequence of action:
1. Settings
2. The telephone
3. Menu (three dots)
4. Select a firmware file
Confirmation of installationThe device will reboot to Recovery mode and begin the verification and installation process, displaying the Mi logo and progress bar, at which point it is strictly forbidden to turn off the phone or remove the battery (if it is not removable, which is true for the Note 3 Pro), the process can take up to 15 minutes.
💡
If the system writes “Failed to update” after selecting the file, try renaming the firmware file to update.zip, although modern versions of MIUI usually recognize the original name.
Once installed, the smartphone will automatically restart. The first run after the upgrade can last longer than usual — up to 5-7 minutes. This is normal, as the system optimizes applications and rebuilds the cache. Be patient and do not try to reboot the device forcefully.
Solving Common Errors During Updating
Even with strict adherence to the instructions, errors can occur, and one of the most common is the message “Can’t verify update”, which happens if you try to roll back to an older version or move from Chinese firmware to global without unlocking the bootloader.
To switch between regions (for example, from CN to Global) or to downgrade the Android version, an unlocked bootloader is often required. Without this procedure, the MIUI security system will block the installation of unverified software. Unlock requires an application through the Mi Unlock Tool and waits from 3 to 7 days.
⚠️ Warning: Unlocking the bootloader will result in the complete deletion of all data from the device. Make sure the backup is made on an external media or in the cloud.
Another problem is a “bootloop” when the phone gets stuck on the logo. If that happens, try entering Recovery mode (pressing the power button and volume up) and selecting Wipe Data, which will delete all user data, but can save the system.
The table below will help diagnose the problem by the error code or symptom:
| Symptom/Error | Probable cause | Decision |
|---|---|---|
| Can't verify update | Blocking the loader or changing the region | Unlock Bootloader or change the firmware type |
| Cyclical reboot | Conflict of system files | Wipe All Data (Recovery) Reset |
| Phone's off. | Record interruption or battery failure | Charging in the off state, trying to log in to Fastboot |
| The network is not working after the update | The Basic Modem Error | Fastboot Flashing with Clearing of All Partitions |

Android 7.0 Nougat features on Redmi Note 3 Pro
After a successful update, you’ll notice changes in the interface and functionality. Android 7.0 Nougat brought multi-window support to the Redmi Note 3 Pro, although it’s not as convenient on a 5.5-inch screen as it is on tablets.
Doze optimization has become more aggressive, which has positively affected battery life. The smartphone better manages background processes, less likely to consume battery power in idle. However, some users note that notifications from messengers can come with a delay, which is solved by setting up auto-start.
Visually, the MIUI interface on Android 7 has become flatter and minimalist, with changes to the notification curtain, quick access settings and multitasking menu, and for kenzo, this update was the last major release to only receive security patches.
💡
Android 7.0 Nougat is the latest major version of the Redmi Note 3 Pro OS, providing compatibility with most modern banking and services applications.
