What is it? OTA-Update and why you need it

term OTA (Over-The-Air literally translates as "over the air" — that is, the update is transmitted to the device over a wireless network (Wi-Fi or mobile Internet:

• 📱 Update MIUI/HyperOS — New version of the shell with interface changes, bug fixes and optimizations.
• 🔒 Security patches – monthly updates from Google, closing Android vulnerabilities.
• 📺 TV firmware – adding support for new video formats (like Dolby Vision) or fixing sound problems.
• ⚙️ An update for smart devices, such as Mi Band or Roborock, improves sensor accuracy.

Main advantage OTA — You don't have to plug it into a PC, download the firmware manually, or use special programs like the Mi Flash Tool, and it finds the update itself, downloads it in the background, and offers to install it at a convenient time:

• ⚠️ Dependence on Xiaomi servers – if they are overloaded, downloading can take hours.
• ⚠️ Risk of “getting a brick” – when the process is interrupted, the device may stop turning on.
• ⚠️ Not always stable - new versions MIUI Sometimes they contain bugs that the manufacturer learns after the release.

Interesting fact: Xiaomi uses a phased release OTA. First, random users (1-5 percent of the total base) get the update, then — if there are no mass complaints — the update is distributed to everyone, so your friend could get a new firmware on the same model a week earlier.

How to check for availability OTA-updates to Xiaomi

For Xiaomi TVs (Mi TV, Redmi TV)

Path: Settings → On TV. → System Update. It can also display the status of "Update Checker" -- that's OK, because TVs check servers less often than smartphones.

It's important! On some models (e.g. Mi). TV 4S or Redmi Smart TV X) before upgrading, you need to disable Auto Update if you want to control the process, otherwise the TV may start installation at the most inopportune time, for example, while watching a movie.

Updates for gadgets are checked through their proprietary applications:

• 📱 Mi Fitness – for fitness bracelets Mi Band.
• 🤖 Mi Home – for smart lamps, sockets and robot vacuum cleaners Roborock.
• 🎧 Mi Earphones for Xiaomi AirDots headphones.

|-------|-----------|---------------|--------------|

| Through recovery. | Low. | No. | Only if you have a backup (nandroid backup) |

| Through Fastboot. | Medium | Yes. | For most models, the PC is required. |

| Through EDL | Tall. | Yes. | For “brick” devices, an authorized account is required. |

| Through OTA-packet | Low. | No. | Only if there is an official rollback package (rarely) |

The most reliable way is to use Fastboot:

2. Unpack the archive and run the Mi Flash Tool on your PC.
3. Connect your phone in Fastboot mode (power button + volume down).
4. Select the firmware file and press Flash.
