Reflashing a Xiaomi smartphone without a computer is a task that seems impossible only at first glance. In fact, the manufacturer has provided several official and semi-official methods for updating the firmware through the device itself, and enthusiasts have found workarounds for installing custom builds. But here lies the main trap: without a PC, you lose the βinsuranceβ in the form of the ability to restore your phone through a Fastboot or EDL if something goes wrong.
In this article, we will analyze all the current ways of firmware Xiaomi, Redmi and POCO without connection to the computer - from a secure update through OTA You will learn which models support each method, how to bypass locking the bootloader without a PC (spoiler: this is almost impossible on new devices), and what to do if the phone turns into a brick after firmware. Special attention will be paid to the unique method using the Xiaomi application ADB/Fastboot Tools via Termux is the only way to get low-level access without a computer on some models.
1. Official update via OTA: the safest way
The Over-The-Air (OTA) method is the standard firmware upgrade offered by Xiaomi itself, which does not require a computer, unlocking a bootloader or special knowledge, the main advantage being the minimal risk of βbrickingβ the device, since the update is carried out with a digital signature and compatibility check.

β οΈ Note: If your Xiaomi smartphone is purchased in China (market version) CN), piece OTA-Updates may include firmware without Google Play and with a sinaized interface. To get a global version, you will need manual firmware (see section 3).
2. Manual installation of official firmware through Recovery
If OTA-Update is not available or you want to install a specific version MIUI (for example, MIUI 14 instead of HyperOS, you can use manual installation via stock Recovery.This method works on all Xiaomi models, but requires preloading the correct firmware file.
Instructions:

Important nuances:
- π The battery must be at least 50% charged, otherwise the process will be interrupted.
- π If the firmware is intended for another region (for example, you install the EU ROM Chinese smartphone, you may need to unlock the bootloader.
- π± New models (e.g. Xiaomi) 13T, Redmi Note 12 Pro+) Stock recavators can block the installation of unofficial firmware.

dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/recovery

5. Firmware via Mi Flash (a PC-free bypass)
This is a semi-official method that works for devices that already have an unlocked bootloader, and the bottom line is that you use a cloud service or a remote PC to run firmware, for example, you can rent a virtual machine in the cloud (like AWS or Google Cloud) with the Mi Flash Tool installed, and then connect to it from your smartphone via TeamViewer or AnyDesk.
