The Xiaomi MIUI ecosystem has garnered a massive following worldwide, thanks to its feature-rich interface and affordable devices. However, one of the most debated topics among MIUI enthusiasts is the relationship between bootloader unlocking and software updates. Can you update MIUI after unlocking the bootloader? This question has sparked intense discussions, with some claiming it’s possible, while others warn of potential risks. In this in-depth article, we’ll delve into the world of bootloader unlocking and MIUI updates to provide a definitive answer.
What is Bootloader Unlocking, and Why Do I Need It?
Before we dive into the update conundrum, let’s first understand what bootloader unlocking entails. In simple terms, the bootloader is a low-level program that loads the operating system (OS) on your device. It’s responsible for initializing the hardware components and booting the OS. By default, the bootloader is locked, which means it only allows the device to boot with the official, signed OS image.
Unlocking the bootloader allows you to modify the OS, install custom recoveries, and flash custom ROMs. This process is often necessary for enthusiasts who want to:
- Root their device
- Install custom kernels
- Flash custom ROMs
- Improve performance and battery life
To unlock the bootloader, you need to obtain permission from Xiaomi through their official unlocking tool. This process typically involves applying for an unlocking token, which is then used to unlock the bootloader.
The Risks of Unlocking the Bootloader
While unlocking the bootloader offers a world of customization possibilities, it also comes with some risks. Here are a few things to consider:
- Warranty voidance: Unlocking the bootloader typically voids your device’s warranty. So, if something goes wrong, you might not be able to get support from the manufacturer.
- Security risks: An unlocked bootloader can make your device more vulnerable to malware and other security threats.
- Bricking: If you’re not careful during the unlocking process, you might end up bricking your device (rendering it unusable).
Can I Update MIUI After Unlocking the Bootloader?
Now, let’s get to the million-dollar question: can you update MIUI after unlocking the bootloader? The short answer is yes, but with some caveats.
Official Updates: Xiaomi does provide official OTA (over-the-air) updates for devices with unlocked bootloaders. However, these updates are typically only available for devices with a valid bootloader unlocking token.
Limitations: There are some limitations to keep in mind when updating MIUI on a device with an unlocked bootloader:
- Custom ROMs: If you’ve flashed a custom ROM, you won’t receive official OTA updates. You’ll need to manually update your ROM to get the latest features and security patches.
- Modified system partitions: If you’ve modified system partitions or installed custom kernels, you might not be able to update MIUI using the traditional OTA method.
How to Update MIUI on a Device with an Unlocked Bootloader
Updating MIUI on a device with an unlocked bootloader requires some caution and planning. Here’s a step-by-step guide to help you through the process:
- Backup your data: Before attempting to update MIUI, make sure to backup your important data, including contacts, messages, and files.
- Download the update package: Visit the Xiaomi website or a reputable source to download the latest MIUI update package for your device.
- Use a custom recovery: You’ll need a custom recovery like TWRP (Team Win Recovery Project) to flash the update package. Make sure you have the correct version of TWRP for your device.
- Flash the update package: Use TWRP to flash the update package. Be cautious, as this process can potentially brick your device if done incorrectly.
- Wipe cache and data: After flashing the update package, wipe the cache and data partitions to ensure a clean installation.
Pitfalls to Avoid
When updating MIUI on a device with an unlocked bootloader, be mindful of the following pitfalls:
- Avoid mixing custom ROMs and official updates: This can lead to compatibility issues and potential bricking.
- Don’t flash custom kernels or modules: These can interfere with the update process and cause system instability.

What happens to my warranty after unlocking the bootloader?
Unlocking the bootloader of your Xiaomi device will void its warranty. This is because bootloader unlocking is a complex process that modifies the device’s software, which can potentially cause issues. Once the bootloader is unlocked, the manufacturer will no longer be responsible for any damage or malfunctions caused by the user.
It’s essential to weigh the risks and benefits of unlocking the bootloader before making a decision. If your device is still under warranty, it may be better to avoid unlocking the bootloader to ensure you’re protected in case something goes wrong. However, if you’re willing to take the risk, unlocking the bootloader can provide you with more control over your device and allow you to install custom ROMs and modifications.
Will I lose my data after unlocking the bootloader?
Yes, unlocking the bootloader will erase all data on your device. This is because the process wipes the device clean, removing all personal data, apps, and settings. It’s crucial to backup your important data before attempting to unlock the bootloader. Make sure to save your contacts, photos, and other essential files to a safe location, such as a cloud storage service or an external hard drive.
After the bootloader is unlocked, you’ll need to set up your device again from scratch. This means you’ll need to reinstall apps, restore your settings, and recover your data from backups. Be prepared to spend some time getting your device back to its original state.
Can I relock the bootloader after updating MIUI?
Yes, it’s possible to relock the bootloader after updating MIUI. However, this process is not recommended, as it can cause stability issues and potentially brick your device. Relocking the bootloader can undo the customizations you made after unlocking it, which may result in unexpected behavior or errors.
If you still want to relock the bootloader, ensure you follow the correct procedure to avoid any complications. It’s essential to flash the stock firmware and relock the bootloader using the official tools and guides provided by Xiaomi. Be cautious when attempting to relock the bootloader, as it can be a complex and risky process.
Will updating MIUI delete my custom recovery?
Yes, updating MIUI will overwrite the custom recovery installed on your device. This means you’ll lose access to the custom recovery environment and any modifications you made to it. The update process will replace the custom recovery with the stock recovery, restoring the device to its original state.
If you want to keep your custom recovery, you’ll need to reinstall it after updating MIUI. Make sure to backup your custom recovery image before updating and then reinstall it using a tool like Fastboot or TWRP.
Can I install custom ROMs after updating MIUI?

Before installing a custom ROM, always check the compatibility and ensure you follow the correct installation procedure. It’s recommended to flash a custom ROM that’s specifically designed for your device and the updated MIUI version. Be cautious when installing custom ROMs, as they can potentially cause issues with your device.
Will updating MIUI affect my root access?
Yes, updating MIUI will remove your root access. The update process will overwrite the system files, removing the root permissions and restoring the device to its original state. This means you’ll need to re-root your device after updating MIUI.
