Have you seen notifications of new MIUI or HyperOS versions on your Xiaomi, Redmi or POCO? or does your smartphone make a mistake when you try to upgrade? This problem is familiar to millions of users — according to statistics from Xiaomi Community, one in five owners of the brand’s devices face delays in updates, the reasons can be due to software failures and hardware limitations, and sometimes even regional policies of the company are to blame.
In this article, we will not just list the possible reasons, but analyze them from a technical point of view: from the banal lack of Internet to blocking updates due to anti-rollback (hardware rollback protection), you will learn how to check the status of your device in the queue for an update, what to do for errors like Couldn't verify update, and when to consider the option with manual firmware through Fastboot.
1. Checking the basic conditions: Internet, memory, battery
Before you dig deeper, make sure that the problem isn’t trivial. 90% of the time when updates don’t go is because one of three key conditions is violated:
- 🌐 Stable Internet connection: Updates weigh 1.5 to 3 GB — with weak Wi-Fi or mobile Internet, downloads can be interrupted during the file verification phase.
- 📱 Free space on the device. MIUI It requires at least 500 MB of free space to unpack the update, and HyperOS requires up to 1 GB.
- 🔋 Battery charge above 50%.The system blocks the installation of updates at low charge to avoid bricking in case of sudden shutdown.
How to check:
- Connect to a Wi-Fi network at a speed of at least 10 Mbps (check through Speedtest).
- Open Settings → Memory and make sure that at least 1.5 GB is free.
- Charge your phone to 60%+ or connect to charging during the upgrade.
Connect to stable Wi-Fi |Free 1.5+GB of memory | Charge battery to 60%+|Disable VPN/proxy (if you use)
-->
If all the conditions are met, but the update still does not come, move to the next section. Particular attention: on some models (for example, Xiaomi 12T or Redmi Note 11 Pro+), the system may hide notifications of updates if the device is unlocked through Mi Unlock.
2.Regional restrictions and Xiaomi policies
Xiaomi splits updates by region, and your device may be in the grey area, for example, smartphones for China (CN ROM) get updates earlier than the global version (Global ROM), but are deprived of Google services, and some models (like the POCO F3) are excluded from the list of upgrades in some countries due to legal restrictions.
How to know your region:
- Go to Settings → About Phone → MIUI version.
- If at the end of the version CN is indicated - you have Chinese firmware, EU - European, IN - Indian, RU - Russian (until 2022).
| Firmware region | Features of updates | Examples of models |
|---|---|---|
| CN | Updates are the first to be released, but without Google Services, and often require manual installation. | Xiaomi 13 Ultra, Redmi K60 Pro |
| Global (MI) | Stable updates, but with a delay in 1-3 month CN-version. | POCO X5 Pro, Redmi Note 12 |
| EU | The updates come later than the global ones, but with optimizations for Europe. | Xiaomi 12 Lite, Redmi 10 2022 |
| RU | Support is discontinued for most models after 2022. updates come infrequently. | Xiaomi Mi 11, Redmi 9T |
If your region is RU, the chances of official updates are minimal, and it is worth considering:
- 🔄 Transition to Global ROM (requires unlocking the loader).
- 📦 Install custom firmware (for example, LineageOS or Pixel Experience).
- ⚠️ Use of the VPN change in region (risky, may result in the blocking of the Mi Account).

3. Xiaomi server errors and Mi Account problems
Even if your device is fully ready to upgrade, the problem may be on Xiaomi's side.The company's servers regularly overload, especially after new versions are released. MIUI/HyperOS. For example, in the first days after the announcement of HyperOS 1.0 October 2023 year-over 40% Users have been affected by the Couldn't download update package error.
How to check the status of servers:
- Open the Downdetector website and look at the crash schedule.
- Check out Xiaomi’s official Twitter for technical announcements.
Another common problem is linking to your Mi Account.
- 🔒 Belong to multiple accounts on one device,
- 📵 Deleted Mi Account without untieting it from the phone,
- 🚫 They were blocked for violating the rules (for example, for frequent changes of regions),
The system can block access to updates.
- Go to Settings → Accounts → Mi Account and make sure that only one account is linked.
- If your account is blocked, try to restore access via account.xiaomi.com.
- In extreme cases, reset via Settings → Additional → Restore and Reset, but it will delete all data!
What to do if Xiaomi servers are not available?
⚠️ Note: If you see Mi Account authorization failed, it means that your device is linked to an account that has been deleted or blocked. You can only restore access through Xiaomi support - self-unblocking attempts can lead to complete data loss.
4. Anti-rollback locking and other hardware restrictions
Xiaomi is actively using the Anti-Rollback mechanism, which prevents the firmware from rolling back to an older version, which can permanently block updates if you:
- 🔙 We tried to get back to the old version. MIUI via Fastboot.
- 📥 Install custom firmware with a downgrade version of Android.
- 🔧 Changes to the anti section through EDL-regime.
How to check the status of the anti-rollback:
- Install the CPU-Z app and check the Hardware string.
- If it has an ARB or Anti tag, your device is locked.
- Compare the current version with the anti-rollback table.
If the antirollback worked, the options are limited:
- 🔄 Xiaomi’s official service center (sometimes can drop the flag for a fee).
- 📦 Installation of custom firmware with bypass ARB (risky, and may lead to a brick).
- 🆕 Buying a new device (in severe cases).
Other hardware reasons:
- 💾 Damaged memory (eMMC/UF). If the phone overheats frequently or crashes into Bootloop, check the health of the drive through the phone. ADB: adb shell dumpsys diskstats Look for lines with bad blocks.
- 🔋 If the battery is inflated or its capacity has dropped below 60%, the system can block updates.
💡
If your device is blocked with anti-rollback, DO NOT try to stitch it through the Mi Flash Tool without understanding the process. anti_version — Sometimes it can be dropped through official channels.
5. Manual update: step-by-step instruction
If automatic updates don’t work, there’s still a manual option, which is suitable for 90% of Xiaomi devices, but requires caution.
Step 1. Download the correct firmware:
- Go to the official website.
- Select your model (e.g. Redmi Note 11 Pro+5G).
- Download Recovery ROM (for installation via stock recovery) or Fastboot ROM (for firmware via PC).
Step 2. Install the update:
- 📱 Recovery: Rename the file to update.zip. Put it in the root of the phone's memory. Go to Settings. → The phone. → Updating the system → Three points. → Select the update file.
Through Fastboot (for experienced):
- Unpack the downloaded archive.
- Connect your phone to your PC in Fastboot mode (press Power + Vol−).
- Run the Mi Flash Tool and select the folder with the firmware.
💡
Manual updates via Recovery are safer than through Fastboot, but only work if the firmware version is newer than the current one. Downgrading will require unlocking the bootloader.
6. Alternative methods: custom firmware and ADB-team
If the official methods don’t work, informal solutions remain, and they are suitable for advanced users and owners of older devices that Xiaomi no longer supports.
Option 1: Custom firmware (TWRP + Custom ROM)
- 📌 Popular firmware: LineageOS – pure Android without MIUI. Pixel Experience – ported Pixel-interface. Xiaomi.eu – optimized MIUI for global devices. 🔧 Required: Unlocked bootloader (via Mi Unlock Tool) Installed custom recovery (TWRP Or OrangeFox).
