What to do if Xiaomi device is not updated: from errors to manual firmware

You try to upgrade a Xiaomi, Redmi or POCO smartphone, but the system persistently issues an error "Can't download the update" or just hangs in the verification phase? Or maybe your Mi TV hasn't received the latest versions of the software for years, although the manufacturer promised support? This problem is familiar to millions of users - according to statistics from the MIUI Community, one in five requests for support is associated with the inability to update.

The reasons can be in both trivial network failures and deep system conflicts, from locked regions to damaged memory areas. In this article, we will examine all possible scenarios, including the rare cases when a device gets stuck on the logo after a failed update. You will get not only standard tips like “reboot the device”, but also exclusive methods for advanced users, from forced unlocking the bootloader to manually stitching through Fastboot.

Special attention will be paid to devices older than 3 years (for example, Redmi Note 8 Pro or Mi 9T), which often lose official support, but can receive updates through alternative channels, and for Mi TV owners, a separate section has been prepared with instructions to circumvent regional restrictions.

1. Checking the basic conditions before updating

Before you get into the technical wilds, make sure that the problem is not on the surface. According to statistics from Xiaomi Service Center, 42% of requests for “non-renewable” devices are resolved at this stage.

Start by checking four key parameters:

• 📶 Internet connection: Updates weigh 1.5 to 3 GB. Connect to a 5 GHz network (if any) or use mobile internet with unlimited rates. VPN and proxy can block Xiaomi servers - turn them off.
• 🔋 Battery charge: the minimum threshold for upgrades is 50%, but it is better to charge up to 80%. On some models (e.g. POCO F3), when the charge is low, the system will not even show the Update button.
• 📱 Free space: At least 4-5 GB is required on the system partition. Check Settings → Storage. If memory is scarce, transfer the photo/video to a memory card or PC.
• ⏳ Time and Date: Incorrect settings can knock certificate verification. Automatic sync must be enabled (Settings → Additional → Date and Time).

If one of the items is not met, the system can silently "ignore" update attempts or give an error Couldn't download (code 24), especially for devices with custom firmware (for example, LineageOS), where the system clock often crashes.

2. Common update errors and their codes

Xiaomi uses its own system of error codes, which are rarely decrypted in the interface. Below is a table with the most frequent codes and their value:

If your code is not in the spreadsheet, check it on the official MIUI forum - there is an extended database. Please note that the codes ERROR_403 and BOOTLOADER_LOCKED are often found on devices purchased in China (versions with the prefix CN in the model).

3 Manual update via Recovery Mode

If the OTA (over-the-air) automatic update doesn’t work, the most reliable way is to install firmware through Recovery, a method that works for all Xiaomi models, including TVs (for which the instruction is slightly different – see 6).

Step-by-step:

1. Download the correct firmware: 🌐 For smartphones: official website MIUI Downloads. Choose the Recovery ROM version (not Fastboot!). 📺 For TVs: Support section Mi TV. Look for a file with the.zip extension.
2. Transfer the file to the device: 📱 Smartphone: place the ZIP- file in the root folder of internal memory (not in the folder!). The file name should not contain Cyrillic or spaces. 📺 Television: use the USB- format drive FAT32 (max. 32 GB).
3. Start Recovery Mode: 📱 Smartphone: turn off the device, then press the Power Button + Volume up for 10 seconds. 📺 Television: on the remote, press Menu + Volume down for 5 seconds (for 2020+ models).

Select a file and install it.

• From the Recovery menu, select the language (if any), then Install update.zip to System.
• Confirm the installation and wait for the completion (it will take 5-15 minutes).

Method 2: Using VPNs with servers in the “right” countries

• 🌍 Install VPN- an application (e.g. ProtonVPN or Windscribe).
• 📍 Connect to a server in India, Indonesia, or Turkey (these regions are usually the first to receive updates).
• 🔄 Go to the update settings and click "Check again."

1. log out of your current account.

2. Register a new one by specifying a country, for example, India (+91 for phone number).

3. Link the device to a new account and check for updates.-->

⚠️ Warning: Changing your region may cause some settings (such as topics or fonts) to reset. Also note that in some countries (such as China), updates may contain additional system applications that cannot be removed without root rights.

5 Unlocking the Bootloader for Forced Upgrade

If all previous methods fail and the device produces a BOOTLOADER_LOCKED error, you will have to unlock the bootloader. This is an official procedure, but it requires an attachment of the Mi Account and waiting (usually 7-15 days).

Instructions for unlocking:

1. Link your Mi Account to your device: Go to Settings → Mi Account → Device Security. Enable Device Search and Allow OEM Unlock (in the developer settings).

Mi Unlock Tool

• The official utility is en.miui.com/unlock.
• Install Xiaomi USB Drivers (if Windows does not recognize the device).
• Run unlock: 1. Turn off the phone. 2. Press <power button + volume down> to log in to Fastboot. 3. Connect the phone to your PC via USB. 4. In Mi Unlock Tool, press Unlock and wait until it is completed (it may take several attempts).

After unlocking the bootloader, you can:

• 📲 Install custom firmware (e.g. Pixel Experience or LineageOS).
• 🔧 Switch official versions of MIUI through Fastboot (if Recovery doesn't work).
• ⚡ Bypass regional restrictions (but this could violate warranty!)

💡

Unlocking the bootloader will void Xiaomi's warranty. If the device is warranty, contact the service center first - they can flash the device without unlocking.

6 Features of updating Mi TVs

Xiaomi TVs are updated differently than smartphones, and there are pitfalls here. The main problem is regional binding: for example, the Mi TV 4S for Europe (EEA) will not receive an update if it is connected in Asia, and vice versa.

Instructions for manual update of Mi TV:

1. Download the firmware for your model: Check the exact model in Settings → About TV → Model (e.g. L43M5-5AIN). Download the file from the official website (Mi TV section).
2. Prepare USB- Drive: Format: FAT32 (not NTFS or exFAT). Size: up to 32 GB (large flash drives may not be readable). The firmware file should be called update.zip and lie at the root of the disk.

Update through the TV menu

• Insert the USB 2.0 port (usually black).
• Go to Settings → About device → System Update → Update via USB.
• Select the file and confirm the installation.

⚠️ Warning: You can't interrupt the update on Xiaomi TVs, which can lead to "bricking" (the device won't turn on). If the process takes longer than 30 minutes, don't pull the flash drive out, wait for the power to end or turn off.

If the TV doesn’t turn on after the update or shows a black screen, try:

• 🔌 Disconnect from the network for 5 minutes, then turn it on again.
• 🔄 Repeat the update from the same flash drive (sometimes a second try helps).
• 📞 Contact Xiaomi with the model and firmware version (you can see it on the sticker on the back of the TV).

7.Alternative methods: ADB, Fastboot and custom firmware

If none of these methods work, there are still advanced techniques that require technical knowledge, and they should only be used if:

• 📵 The device does not turn on after an unsuccessful update.
• 🔒 The bootloader is unlocked, but the firmware is not installed.
• 🌐 You need a version of MIUI that is not available in your region.

Method 1: Installation via ADB Sideload (for smartphones):

1. Enable debugging over USB (Settings → For Developers).


2. Connect the phone to the PC and start the command:




adb sideload update.zip




3. wait until the end (don't turn off the USB!).

Method 2: Fastboot firmware (requires an unlocked booter):

1. Download Fastboot firmware from Xiaomi's website.


2 Unpack ZIP in a folder on your PC.




3. Run the command line from this folder and do:




fastboot flash all




(Or alternately, run each section: boot, system, vendor, etc.)

Method 3: LineageOS (Pixel Experience):

• ✅ Pros: Regular updates, no bloat (unnecessary applications)
• ❌ Cons: Camera bugs or NFC, loss of warranty, are possible.

8.If nothing helps: contact the service

If you’ve exhausted all options and the device still isn’t updated, there may be a hardware problem:

• 💾 The memory partition (EMMC or UFS) is damaged.
• 🔋 Battery malfunctions (on some models it blocks updates when degradation occurs).
• 🔌 Problems with the power controller (often after falls or moisture).

In this case:

1. Please contact the official Xiaomi service (list of centers: mi.com/global/service/center).
2. If the warranty is over, find an informal service with good reviews (check on Yandex.Maps or 2GIS).
3. Check the cost of diagnosis – in some cases, repairs can be cheaper than buying a new device.

⚠️ Warning: Before visiting the service, back up your data (if the device is turned on). The service can perform a full reset or reflash the device, which will delete all files. Use Mi PC Suite or Google Drive (for contacts and photos) to back up.

If the service refuses to help with the words "the device is not supported", request a written refusal stating the reason. According to the law "On protection of consumer rights" (Article 18) you have the right to repair for 2 years from the date of purchase, even if the warranty period is less.
