Why to Refuse Xiaomi Without a PC and When Itβs Necessary
Reflashing Xiaomi smartphone without a computer is a task that users face when you need to update the system in the field, restore the device after a failure or install custom firmware without a PC at hand. Official methods (via Settings β Software Update) are suitable for most cases, but what if the update βhangsβ, and connect to the Mi Flash Tool is not possible?
In this article, we will discuss three working ways to reflash Xiaomi, Redmi or POCO computer-free: from standard OTA-Updating to manual installation through Recovery and even informal methods using applications, especially focusing on preparing the device to avoid βbrickβ (turning the phone into a βbrickβ), as well as analyzing typical errors and how to solve them. Instructions are relevant for devices based MIUI 12β14 and HyperOS (2026).
β οΈ Important: Firmware without a PC is always risky. If your device is warranted, the official Xiaomi service center may refuse to repair after unauthorized manipulation of the firmware.
1. Preparation of the device: what to do before flashing
Regardless of the method chosen, smartphone preparation is a critical step, and neglecting these steps can lead to data loss, malfunctions or even complete failure of the device.
First, check your Xiaomi model and current MIUI/HyperOS. You can do this in the Settings β About Phone menu. Write down or take a picture of this data, which you will need to choose the right firmware. For example, the Redmi Note 11 Pro+ 5G (veux) and POCO X3 Pro (vayu) use different firmware files.
- π± Save important data: contacts, photos, messages. Use Mi Cloud, Google Drive or a physical memory card. When installing custom firmware, you may need a full reset (Wipe Data).
- π Charge the battery to at least 60 percent, and if the process is interrupted due to a discharge, the phone may stop turning on.
- π Stable Internet connection: Wi-Fi is required to download the firmware (mobile Internet may be interrupted).
- π Unlock the bootloader (if necessary): Unofficial firmware requires unlocking Bootloader. Check the lock status with the command fastboot oem device-info (you need a PC, but this is the only way to find out the status of the device).
β οΈ Note: If you install custom firmware (like LineageOS or Pixel Experience), make sure it is compatible with your model. Installing firmware from another model (like the Redmi Note 10 file on the Redmi Note 10 Pro) will cause permanent damage to system partitions.

Method 1: Official OTA-Update through βSettingsΒ»
The simplest and most secure method is an Over-The-Air (OTA) update, which is suitable for installing official stable or beta versions of MIUI/HyperOS without losing data.
- β Only official firmware from Xiaomi is supported.
- β You canβt go back to the older version (downgrade).
- β Custom firmware is not available (e.g. Global) ROM Chinese-style).
Step-by-step:
- Open Settings β About the phone β System update.
- Click on the three dots in the top right corner and select Download the latest version.
- If the update is available, click Download and wait until it is completed (may take 10β30 minutes depending on internet speed).
- After download, click Set and confirm the reboot.
β οΈ Warning: if the update is βhangβ during the installation phase (more than 20 minutes the logo hangs) MI), Try to force the phone to restart by holding the power button for 10-15 seconds. If the system doesn't start after the restart, go to the Recovery installation method.

3. Method 2: Install firmware through Recovery Mode
If OTA-Update is not available or you want to install full firmware (for example, to recover from a crash), you can use the built-in Recovery Mode. This method is suitable for official firmware in.zip format and does not require unlocking the bootloader.
What you need:
- π Firmware file in.zip format (you can download from the official Xiaomi website or through the Mi Community application).
- π a separate folder on the internal memory or SD-map (e.g., map, downloaded_rom).
Instructions:
- Download the firmware and rename the file to update.zip (required!).
- Place the file in the root of the internal memory or on the SD-map (not nested folders!).
- Turn off your phone and press the button combination to log in to Recovery: For most models: Power + Volume up. For some older devices: Power + Volume up + Volume down.

Install update.zip to System One
β ConfirmWait for the installation to be completed (10-20 minutes) and restart the device.
β οΈ Note: If the phone loads into Fastboot Mode or reboots cyclically after installation, it is not suitable for your model, in which case, try resetting your settings via Recovery (Wipe Data) or installing another version of the firmware.
What if Recovery doesnβt see update.zip?
Method 3: Unofficial firmware via TWRP (only for unlocked bootloader)
To install custom firmware (e.g. LineageOS, Pixel Experience, ArrowOS) or modified versions of MIUI (e.g. xiaomi.eu) you will need:
- π Unlocked bootloader (bootloader).
- π οΈ Installed custom Recovery (TWRP).
- π¦ Firmware in.zip format for your model.
β οΈ Warning: This method voids warranty and may cause the device to operate in an unstable manner. Use it only if you understand the risks!
Step-by-step:
- Install TWRP Recovery (see the XDA Developers forum for specific model instructions).
- Download the firmware and, if necessary, GApps (Google services for firmware without them).
- Boot in TWRP (the button combination is the same as for standard Recovery).
- Backup β Select Partitions β Swipe to Backup.
- Run Wipe (required!): Wipe β Advanced Wipe β Dalvik, Cache, System, Data β Swipe to Wipe
- Install β Select.zip β Swipe to Confirm Flash
- If required, install GApps (similarly).
- Reboot to the system (Reboot β System).
The first download after installing custom firmware can take up to 15 minutes - do not interrupt the process!

If your mobile network is not working after installing custom firmware, check your APN settings or install a patch for your region (look for 4PDA or XDA).
