1. Xiaomi server is not available: 404, 502, 504 errors
The most common cause is server-side problems, and Xiaomi uses geo-sensitive mirrors to distribute firmware, and if your region is restricted (or your server is overloaded), downloads simply won't start, and you can tell by the following:
- โ 404 Not Found error when trying to download firmware from bigota.d.miui.com or update.miui.com
- โ ๏ธ Download starts, but ends by 0.5% with a 502 Bad Gateway or 504 Gateway Timeout error.
- ๐ The update page in the smartphone settings takes a long time to load or shows an empty list
Decisions:
- Change. DNS. By default, Xiaomi can block access through standard DNS ISP. Try Google. DNS (8.8.8.8, 8.8.4.4) or Cloudflare (1.1.1.1).
- Use it. VPN. Connect to servers in Hong Kong, Singapore or India โ these regions are rarely restricted. VPN (Like ProtonVPN, you may not work, you need to pay at a good speed.

3. Lack of memory: hidden requirements MIUI
Even if your Xiaomi has free space, the system can block the download of firmware due to hidden requirements. MIUI reserve up to 3-5 GB for system needs, and if the free space is less than this threshold, the update will not begin.
How to check:
- Open the Settings โ Memory
- Check the "Available" line - if it is less than 4 GB, you need to vacate space.
- Note that internal memory (where the firmware is stored) and SD-The card is different things! The firmware is only downloaded into the internal memory.
What to do:

4. bootloader errors and blocked Bootloader
If the firmware is downloaded but not installed (or the update process is interrupted during the verification phase), the bootloader is to blame. On all Xiaomi, it is blocked by default, and this can interfere with even official updates.
Signs of a problem:
- ๐ด Error "Couldn't verify update package" when trying to install firmware
- ๐ The device reboots in Fastboot with the words "Anti-rollback check fail"
- โ๏ธ In the update logs (Settings) โ The phone. โ Version. MIUI โ press 10 times) an error is visible E1001

5. Internet Connection Problems: Wi-Fi vs. Mobile Network
Xiaomi firmware weighs between 1.5 and 4 GB, and you need a stable connection to download it, but even with good Internet, you can get bugs.
- ๐ถ Downloading via mobile Internet is cut by 50-70% (the provider can restrict large files)
- ๐ When connecting to Wi-Fi, a โNetwork errorโ appears, although other sites are working.
- โณ The download speed of firmware does not exceed 50-100 KB / s (Xiaomi server can artificially limit the speed)
How to fix it:
| Problem. | Decision |
|---|---|
| Downloading via mobile network is terminated | Turn off background restriction for Downloading in Settings โ Annexes โ All applications โ Downloads. โ Use Wi-Fi or connect to another carrier (e.g. Tele2 less likely to restrict traffic than MTS) |
| The "Network Error" Error on Wi-Fi | Reconnect to the router (forget the network and connect again) IPv6 In router settings, try another Wi-Fi (e.g. from your phone in access point mode) |
| Slow download (<100 KB/s) | Use it. VPN (servers in Germany or the Netherlands give better speeds) Download firmware on your PC and then transfer to your phone |
If nothing works, check the date and time settings. Incorrect data can interfere with the connection to Xiaomi servers:
- Go to Settings โ Additional โ Date and time
- Enable Autodetermination or manually set the correct date/time/time zone
๐ก
The most reliable way to download firmware is to use a PC and cable USB. This way you will avoid network problems and download interruptions.
6. Firmware file errors: damaged archives and incorrect hashes
Even if the firmware is downloaded, it can be damaged, and then the installation will end in error.

- ๐ฅ๏ธ Errors when copying a file to your phone
- ๐ต๏ธ File swapping by viruses (if downloaded from third-party sites)
How to check the integrity of the firmware:
- Compare. MD5-The hash of the downloaded file from the official file. MD5 Checker or PowerShell Team: Get-FileHash -Algorithm MD5 "path to file.zip On Android: install the Hash Droid app from Google Play
If the hashes do not match, download the firmware again!
Common errors in a corrupted file:
- ๐จ "Update package verification failedโ (incorrect file signature)
- ๐ง "Installation abortedโ (installation interrupted due to broken data)
- ๐ฆ "Error in /sdcard/.../update.zip" (file-reading error)
If the firmware is damaged, but there is no possibility to download again, try:
- Rename the file to update.zip and put in the root of memory
- Use it. TWRP Recovery for forced installation (if Bootloader is unlocked)
- Unpack the archive on the PC and repackage in ZIP (compressively!)
7. Conflicts with custom firmware and root rights
If your Xiaomi has ever been run by custom firmware (like LineageOS, Pixel Experience) or has a root-rights (Magisk) installed on it, the official updates may not work.
- ๐ Modified boot.img block the verification of the firmware signature
- ๐ A modified system or vendor partition leads to errors. E3003 or E2001
- ๐ ๏ธ Installed Magisk modules (e.g. Xposed or ViPER4Android) conflict with the update

- Back to stock firmware: Download the official Fastboot firmware for your model Sweat it through the Mi Flash Tool with the clean all option
- Update. TWRP (If you are using custom recovery: Install the latest version TWRP For your model from the official website Before updating, make a backup through TWRP โ Backup
โ ๏ธ Note: If you are using Xiaomi.EU ROM Or another custom firmware, return to the official MIUI You just need to use Fastboot!TA This will lead to a brick (the phone will stop turning on).
8 Hardware problems: damaged memory or battery
If all the software methods have been tried, but the firmware still doesn't download, it could be the hardware, and most of the time, it's the hardware.
- ๐พ Damaged memory cells (especially on cheap Redmi models with eMMC)
- ๐ Worn-out battery (if the charge is below 15%, the system blocks updates)
- ๐ถ Faulty module Wi-Fi/4G (The phone cannot permanently download a large file)
How to diagnose:
- Check battery health: Enter the code in the phone number: ##4636## Go to Battery Information and see the wear level If the capacity is less than 80% of the factory - the battery needs to be replaced
- Test Memory: Install the App A1 SD Bench or AndroBench โ Start a Read/Write Test โ If the speed is below 50MB/s, the memory is degraded
- Check Wi-Fi module: Connect to different Wi-Fi networks if speeds are low everywhere (<5 Mbit/s) - module malfunctioning
Decisions:
- ๐ง If there is a problem in memory, contact the service center to replace it. eMMC/UF (on new models, memory soldered to the motherboard)
- ๐ If the battery is to blame, replace it (cost for Redmi Note 11) ~1500โ2500 rubles.)
- ๐ก If Wi-Fi is not working, try downloading the firmware through USB-cable from PC or use mobile Internet
Critical information: On some Xiaomi models (e.g., on some Xiaomi models, POCO X3 Pro) the charge cycle counter is reset after the battery is replaced and the phone is again updated normally.
