Why does not come update to Xiaomi Mi 9T: all the reasons and ways to solve

Xiaomi Mi 9T (also known as Redmi K20 in some regions) is one of the most popular smartphones of the brand, but owners often face the problem of not having MIUI updates. You check the Settings → Phone → System Update, and it is empty or there is a sign that says “No updates available” although the forums are already discussing the latest versions? In this article, we will analyze all possible reasons why updates do not come automatically, and what to do about it – from basic checks to manually installing the firmware.

It's important to understand that Xiaomi uses a staged rollout, where the new version of MIUI first rolls out to a limited number of devices and then to others, which means that even if the update is officially announced, your Mi 9T may get it later, but if it's more than a month since it was released and the update is not there, it's time to dig deeper.

We will also touch on the hidden settings. MIUI, This is a good way to get around regional restrictions (for example, if your smartphone is tied to a Chinese or global firmware branch — FAQ answers to frequent questions and checklist for self-diagnosis.

1.Phase-by-Phase Updates: Why Your Mi 9T Isn't in Line

Xiaomi rarely releases updates for all devices at once, instead using a staged rollout system that works like this:

• 📅 First wave (1-7 days after release): update receives ~10% of users (usually those who participate in beta testing or have "clean" firmware without modifications).
• 📊 Second Wave (7-14 days): More ~30% of devices without critical bugs.
• 🌍 Full release (14-30 days): Update is available to everyone.

If your Mi 9T didn't get an update in the first few days, that's fine. But if it's been more than a month and Settings → About Phone → System Update is still empty, the problem lies deeper.

• 🔍 Firmware region: Chinese (CN), Global (Global) and European (EEA) version MIUI They're updated at different times. How do you check your version? Go to Settings. → The phone. → Version. MIUI And look at the suffix (for example, V12.5.3.0.RFHEUXM — it EEA).

To speed up the process, you can manually check for updates: open the Update app (or Updater), click on the three dots in the upper right corner and select Update package. Sometimes this works, even if the automatic check doesn't show anything.

2. Regional restrictions: Your firmware is wrong

One of the most common reasons for the lack of updates is the discrepancy between the firmware region and Xiaomi servers, because the Mi 9T was sold in different regions under different names:

• 🇨🇳 Redmi K20 — Chinese version (firmware) CN).
• 🌍 Xiaomi Mi 9T — Global version (Global version).
• 🇪🇺 Xiaomi Mi 9T — European (EEA, with pre-installed Google services and compliance GDPR).

If you bought a smartphone in China or installed Chinese firmware manually, you will never get updates for the global/European branch. The same thing works in reverse: there will be no updates for the Chinese version on the global Mi 9T.

How do you check your version? Go to Settings → About Phone → MIUI Version and look at the last block of letters in the build number. If there's CN, and you're waiting for a global update, it won't be there.

⚠️ Note: If you install firmware in a different region (for example, Chinese on the global device), Google services may stop working, NFC Or mobile, and there's also a risk of blocking your smartphone when you next update. OTA.
