You're trying to upgrade your Xiaomi, but the system stubbornly refuses to download or install a new version of MIUI? hung progress bar, errors like Couldn't download or endless check updates - these are problems faced by one in five users of the brand's smartphones. 80% of the time, it's not the "crooked hands" that are to blame, but system bugs that can be fixed without visiting the service center.
In this article, we’ll look at all the possible reasons why the update doesn’t load on Redmi, POCO or Mi, from a trivial lack of disk space to an antivirus lock. And then we’ll give you step-by-step instructions for every situation, including manually installing firmware through Fastboot and recovering through Recovery. If you’ve tried rebooting your phone and resetting your network settings, read on: there are solutions that aren’t in the standard guides.
1. Internet connection problems: why the update is not downloading
The most common reason is an unstable Internet connection, and even if you have Wi-Fi, your smartphone can “lose” data packets when you download a large firmware file (usually weighing 1.5-3 GB), especially for the POCO X3, Redmi Note 10 and older Mi 9 models, where the Wi-Fi module is sensitive to interference.
How to check:
- 📶 Switch to mobile (if the update is downloaded via Wi-Fi) or vice versa. Sometimes mobile operators block traffic for updates.
- 🔄 Reset your network settings: go to Settings → SIM-maps and mobile networks → Resetting network settings.
- 🛡️ Turn it off. VPN Proxies or proxies – they can redirect traffic through servers where access to updates is blocked.
If the problem persists, try to change it. DNS-server:
- Open the Settings. → Wi-Fi.
- Click on your network → Change the network → Additional settings.
- In the DNS field, type 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
⚠️ Note: If you are using a corporate or learning network (e.g., in an office or university), the administrator may have blocked access to Xiaomi update servers.
2. Memory Lack: Why the System Can't Unpack the Update
MIUI updates require a minimum of 3 to 5 GB of free space on the internal drive — even if the firmware file itself weighs 2 GB. The fact is that the system creates temporary files to check and unpack the update. If there is less memory, the process is interrupted with an Insufficient storage error or simply freezes at 0%.
How to make room:
- 🗑️ Remove the app cache: Settings → Annexes → Application management → Clear the cache (select the most "heavy" applications).
- 📸 Transfer the photo/video to SD-Use Google Photos or Mi Cloud to automatically sync.
- 🎮 Remove unused games – they take hundreds of megabytes (check in Settings) → Memory).
- 🔍 Find large files through Files → Memory analysis.
☑️ Minimum requirements for updating MIUI
If even after cleaning up space is not enough, try installing the update via Recovery:
- Download the firmware for your model from the official Xiaomi website (select the Recovery ROM version).
- Rename the file to update.zip and move it to the root of internal memory.
- Press Volume Up + Power to enter Recovery.
- Select Install update.zip and confirm the installation.
⚠️ Note: On some models (POCO F3, Redmi K40) To enter Recovery, you need to use the Volume Up combination + Nutrition + Home (if there is a physical button) specify the combination for your model in the instructions.
Xiaomi server errors: why the update is not found
Sometimes the problem isn't with your phone, it's with Xiaomi's servers, and the company releases updates in waves, first for 10 percent of users, then for 50 percent, and then a week later for everyone. If your smartphone isn't in the first wave, it'll write No updates available, even if the firmware is out.
How to get around the restriction:
- 🔄 Change the firmware region (if your model supports global versions:
Wait 2-3 days
Use VPNs with servers in India or Europe
How do you know if the firmware is available for your model?
| Firmware region | Code. | Features |
|---|---|---|
| Russia | RU | Localized for Russia, there are pre-installed services (Yandex, Mail.ru) |
| Global (Europe) | EEA | No Russian services, but with Google support |
| India | IN | Optimized for local networks, often updated first |
| China | CN | No Google services, only for Chinese Mi accounts |
Important: If you install firmware for another region, some features (such as NFC for payment in Russia) may stop working. Before changing the region, back up to Settings → Additional → Backup.
4. Blocking by antivirus or firewall
Antiviruses (such as Avast, Kaspersky) and built-in firewalls can block downloads of updates, mistaking them for suspicious activity, especially for rooted devices or phones with custom firmware.
How to check:
- 🛡️ Temporarily disable the antivirus and try to download the update again.
- 🔍 Check the lock log in the antivirus settings – there may be a record of the block updates.miui.com.
- 📱 Turn off the built-in protection. MIUI: Settings → Annexes → Application management → Security → Shut down.
💡
If the update does not download after disabling the antivirus, try adding updates.miui.com to the firewall exceptions.
5. Damaged system files: why the update "cannot be installed"
If the update is downloaded but the installation produces an Installation failed or Verification failed error, the corrupted system files are to blame.
- Incorrect rooting (Magisk, SuperSU)
- Remove system applications (Mi Browser, GetApps)
- Aborted previous update.
Decisions:
- 🔧 Restore system applications through ADB: adb shell cmd package install-existing com.miui.browser (replace com.miui.browser with remote application package).
- 🔄 Make a reset to factory settings (pre-save data!).
- 📥 Install firmware via Fastboot (instruction below).
