Xiaomi Redmi 9 is one of the most popular budget smartphones, but even it is not immune to problems with updates. You try to install a fresh version of MIUI, but the system stubbornly gives out an error, the download freezes by 0% or the device does not see available updates at all? This situation is familiar to thousands of users - and it has at least a dozen reasons, from a banal lack of memory to blocking from Xiaomi servers.
In this article, we will not just list the possible problems, but analyze them from the technical side: why the update does not download, install or interrupt in the middle, what to do if the Redmi 9 βhangsβ on the logo after the update, and how to manually flash the device if the automatic method does not work.
1. Xiaomi servers are overloaded or unavailable
The first and most common reason Redmi 9 doesnβt see updates is because of the server-side issues Xiaomi has, which regularly updates dozens of models at once, and in the days after the server release, it often fails to handle the load.
- π The βCheck Updatesβ button is spinning endlessly, but there is no result.
- β οΈ Couldn't download. Please try again later.
- π The download starts, but stops by 5-50% with the message about the network.
How to check if the servers are to blame? Go to the official MIUI website and try to download the firmware for Redmi 9 manually. If the page loads slowly or gives an error, the problem is definitely on the Xiaomi side, in which case you only have to wait (usually no more than 2-3 days) or try alternative methods of updating (about them below).
Another nuance: Xiaomi is a practice of gradual rollout, which means that the update gets 1-5% of users first, then a part, and so on. If your Redmi 9 is not in the first wave, the update can hang indefinitely. You can check this through Settings β About Phone β MIUI version β if your version is older than the one announced on the site, but the update does not come, most likely, you have not yet included in the distribution.
2. insufficient memory or damaged update cache
MIUI requires a minimum of 1.5 to 2 GB of free space to download and unpack the update. If Redmi 9 has less than 1 GB left, the system won't even show an available update. But there's a more insidious problem, a corrupted update cache that accumulates in the /cache folder and can block new files from downloading.
How to clean the cache:
- Go to Settings β Storage β Cleaning.
- Select βUpdate Cacheβ (or βOther Dataβ if there is no such item).
- Press "Clear."
- Restart your phone and check for updates again.
Make sure it's free. β₯2 GB memory|Connect to a stable Wi-Fi|Battery charge β₯50%|Clear the update cache|Turn it off. VPN/proxy-->
If the cleanup didnβt help, try removing the update folder manually:
- Connect Redmi 9 to your PC and enable File Transfer Mode (MTP).
- Go to the Internal Storage folder β downloaded_rom.
- Delete all files with the.zip extension.
- Reboot the phone.
β οΈ Note: Do not delete files from the folder MIUI or system, it could cause a system failure. downloaded_rom.
3. Blocking updates due to region or firmware modification
Xiaomi is actively blocking updates for devices with:
- π Unofficial region (for example, if you bought Redmi 9 for India, but use it in Russia).
- π§ Custom firmware (TWRP, LineageOS, Pixel Experience).
- π Unlocked bootloader (even if the firmware is original).
Check your region in Settings β About Phone β MIUI Version. If the end of the firmware name is IN (India), CN (China), RU (Russia), etc., but you are in another region - updates may not come.
| Problem. | How to check | Decision |
|---|---|---|
| Regional incongruity | Code in MIUI version (IN, RU, EU) | Change region via fastboot or flash the global version |
| Custom firmware | Presence of TWRP or unofficial Recovery | Return to stock MIUI via Mi Flash Tool |
| Unlocked loader | This device is unlocked when downloading | Close the bootloader in an official way (requires authorization in Mi Account) |
To change the region without losing data, you can use the Mi Region Changer tool (requires an unlocked bootloader). If the bootloader is locked, the only option is to flash the full MIUI version for your region via fastboot.

4. Download errors: from network to antivirus
If the update starts to download but is interrupted, it may be the fault of:
- πΆ Unstable Internet connection (especially on mobile data).
- π‘οΈ Antivirus or firewall that blocks download.
- π VPN/Proxy that prevents connection to Xiaomi servers.
- β³ Timeout server (if the file is too large).
Decisions of the order:
- Switch to Wi-Fi β Mobile internet often cuts off large downloads.
- Turn off VPN/proxy in your network settings.
- Add an exception for MIUI in the antivirus (e.g. Avast or Kaspersky).
- Use another DNS: Settings β Wi-Fi β Additional β IP Settings β Static DNS 1: 8.8.8.8 DNS 2: 8.8.4.4
If the download stops at the same percentage (for example, 99%), try:
- π Reboot your phone and router.
- π± Download the firmware manually from the official site and install through the Software Update β Select a file.
π‘
If the update weighs more than 1.5 GB, download it at night β at this time, Xiaomi servers are less loaded, and the probability of a break is lower.
5. Installation failures: from battery to damaged files
Did the update jump, but it's not installed?
- π Low battery charge (less than 30%).
- π A damaged update file (decreased or damaged) CRC-mistake).
- π§ Conflict with installed applications (especially with Magisk or Xposed).
- π οΈ A damaged system (for example, after a failed root access).
The first thing you need to do is check the integrity of the file.
- Download the firmware manually from the official website.
- Compare. MD5-hash file with what is listed on the site (use the Hash Droid app).
- If the hashes donβt match, download again.
If the file is complete, but the installation is still not going:
- π Connect your phone to charge (even if the battery is 50%).
- π± Reboot to Recovery Mode (clip the power supply) + Volume up) and select Apply update from ADB.
- π§ If there is root, delete the folder. /data/ota_package via Root Explorer.
β οΈ Warning: If you install E:footer is wrong or E:signature verification failed, it means that the firmware file is corrupted or not intended for your model!
6.Forced Upgrade: From Recovery to Fastboot
If all of the above methods fail, you have to force the firmware. There are three ways:
- Through Recovery: Download the full firmware (.zip) for your model from the official website. update.zip. Put it in the root of your internal memory. Go to Recovery Mode. + Volume up. Select Install. update.zip to System.
- Through Fastboot (requires unlocked bootloader): Download Mi Flash Tool and firmware (.tgz). Unpack the firmware into a folder without spaces. Connect your phone in Fastboot mode (Power) + Volume down. In the Mi Flash Tool, select the firmware folder and press Flash.
- ADB Sideload: Adb sideload update.zip (requires USB debugging enabled and ADB running).
Important: Forced firmware will reset all settings (but not files in memory). If you have the bootloader unlocked, it will be blocked again after the firmware is installed, you will have to repeat the unlock procedure.
π‘
If the phone doesn't turn on after forced firmware or is stuck on the MI logo, try repeating the process with another firmware version (such as an older one).
7. Xiaomi has stopped supporting Redmi 9: what to do?
Xiaomi has officially stopped releasing regular updates to Redmi 9 since 2026, which means that new MIUI versions for this model will not be released, and recent updates may contain critical bugs that the company will not fix.
- π Custom-based firmware ROM (LineageOS or Pixel Experience).
- π§ Manual installation of security patches via Magisk (requires root).
- π± Use alternative launchers (e.g. Nova Launcher) to simulate a new version MIUI.
For custom firmware installation:
- Unlock the bootloader through the official Xiaomi tool.
- Install TWRP Recovery for Redmi 9.
- Download the right firmware (for example, with XDA Developers).
- Sweat through TWRP (donβt forget to backup!).
β οΈ Attention: Castom firmware may contain bugs that affect the camera, sensors or mobile network. Before installing, check for reviews about a particular build on forums.
