Xiaomi Pad firmware: official and custom methods with unlocking the bootloader

Xiaomi Pad’s firmware is a challenge faced by both experienced users and newcomers who want to upgrade, install custom firmware or restore the device to work after a failure. Unlike smartphones, Xiaomi tablets have their own nuances, from the features of unlocking the bootloader to the compatibility of firmware with different models (Pad 5, Pad 6, Pad 6 Pro, etc.). This article covers all the current methods of firmware – from official updates via MIUI to manual installation through Fastboot and TWRP, taking into account the latest changes in Xiaomi’s policy (for example, binding to the account the account of the 20 year 23 account).

We're going to look at not only standard scenarios, but also rare cases: what to do if a tablet doesn't turn on after a failed firmware, how to get around an anti-rollback error, and why some firmware requires a rollback to an older version of MIUI before an update. Special attention is paid to security - from 2026, Xiaomi will block the bootloader on new devices 72 hours after the first activation, if the account is not tied, which means that it can be risky to postpone unlocking until later.

Preparation for firmware: what you need to know before you start

Before you start firmware, it is critical to determine the current state of the device and the purpose of the procedure, and firmware may be needed in three cases:

• 🔄 System Update – Installation of a New Version MIUI HyperOS (for 2026 models) via official channels or manually.
• 🛠️ Recovery – if the tablet is stuck on the logo, does not turn on or gives errors such as bootloop.
• 🚀 Install custom firmware – for example LineageOS or PixelExperience for advanced features.

For any of these tasks, it will be necessary to:

• 💻 Computer on Windows 10/11 Linux (for Fastboot commands).
• 🔌 Cable USB-C Original or certified (cheap cables can cause data transmission errors).
• 🔋 Battery charge of at least 60% - when discharged during firmware, the risk of "bricking" increases.
• 📥 Firmware that is suitable for your model (for example, tissot for Pad 5 or liuqin for Pad 6 Pro).

⚠️ Note: If your Xiaomi Pad is purchased in China (suffix version) CN), Global version of the firmware (Global or EEA) It can lock the device due to regional restrictions. → The phone. → Version. MIUI.

Also note that Xiaomi has tightened the rules for unlocking the bootloader since 2023, and now requires:

1. Link your Mi Account to your device in advance (before the bootloader is blocked).
2. Wait 168 hours (7 days) after the tether if the device is new.
3. Use the official Mi Unlock Tool software (older versions do not work).

Official ways of firmware: update via MIUI and Recovery

If your goal is to simply upgrade to the latest version, start with the official methods, which are safe, do not require unlocking the bootloader and keep the warranty.

Method 1: Air Update (OTA)

1. Open Settings → About the phone → System update.
2. Click Check for updates.
3. If the update is available, download it and confirm the installation.
4. Wait for the reboot (usually takes 5-15 minutes).

Method 2: Manual updates through Recovery

If OTA does not work (for example, due to a failure of Xiaomi servers), you can install firmware manually through stock Recovery:

1. Download the official firmware (.zip) for your model from MIUI Downloads (select the Recovery ROM version).
2. Move the file to the root directory of the tablet’s internal memory (not to folders!).
3. Turn off the device, then press Power + Volume up to enter Recovery.

Step 2: Install custom firmware

Example for LineageOS:

1. Download firmware (.zip) and, if necessary, GApps (Google services).
2. Transfer files to a tablet or flash drive (formatted in FAT32).
3. In TWRP, select Wipe → Advanced Wipe and select Dalvik, Cache, System, Data.
