The popular 2019 Redmi Note 8T smartphone often wonders about the possibility of getting the latest software features. The device, based on the MediaTek Helio G90T processor, originally shipped with the MIUI 10 shell, but quickly received updates to MIUI 11 and MIUI 12. However, with the release of MIUI 13, the situation for this model has become ambiguous, generating a lot of rumors and technical discussions in the community.
Official support for the smartphone by Xiaomi has come to an end, which means the lack of direct OTA-Updates to new versions of Android and shell MIUI However, enthusiasts and developers continue to look for ways to extend the life of the gadget. 8T not received official MIUI 13 What are the alternatives and whether to risk stability for new features.
If you are a user of this device, you need to be clear about the difference between official firmware, global versions for other regions and custom builds. Misinterpreting the available information can lead to device overwork or loss of personal data. Below is a detailed analysis of the situation and instructions for those who are ready for experimentation.
Official Support Status for Redmi Note 8T
Xiaomi has traditionally provided two major Android updates for its mid-range and budget smartphones.The Redmi Note 8T, launched with Android 9 Pie, received an update to Android 10, its latest major update of the operating system.The MIUI 13 shell, based primarily on Android 11 and Android 12, is not formally designed for devices whose support cycle has expired.
The MediaTek Helio G90T processor, while powerful for its time, requires specific adaptations from the chipmaker to work with new versions of Android. As MediaTek and Xiaomi redirected resources to support newer platforms, the official repositories for the Redmi Note 8T stopped receiving security updates and MIUI 13 functionality packages.
However, in some regions, there were strange bursts of activity when users found firmware files labeled MIUI 13. It is important to understand that most often these were either global versions for other models with similar hardware, or fake builds. Officially, the status of the device is marked as "End of Life", which means a complete stoppage of development on the part of the vendor.
⚠️ Warning: Trying to install official firmware from another Xiaomi model (even with a similar name) through the standard Recovery menu can lead to bootloader locking or damage to system partitions.
Users should accept that there is no legal way to get MIUI 13 out of the box, and all the further steps are in the informal way that requires unlocking the bootloader and having certain technical skills.
Technical limitations and compatibility of iron
The main obstacle to the introduction of MIUI 13 on the Redmi Note 8T is not only the political decision of the company, but also hardware limitations. the new shell MIUI 13 contains a lot of background processes, improved animations and protection systems that require more RAM and processing power. the old Linux kernel, which is based on Android 10 for this model, is not compatible with the new security modules of Google and Xiaomi.
In addition, the power optimization of MIUI 13 is designed for more modern power controllers. When trying to force the installation of a new system, users often face accelerated battery discharge and overheating of the case, this is due to the fact that the drivers for the Helio G90T in new versions of Android are not in normal mode, but in emulation or compatibility mode, which reduces overall efficiency.
Also worth mentioning is the boot and recovery partition problem: the partition structure in MIUI 13 is different from that used in MIUI 12. Without the partition table, installation is impossible. That's why official ports were not created - the risk of critical errors was too high for the mass user.

Alternative methods of installing MIUI 13
Despite the lack of official support, the XDA-Developers community and 4PDA forums offer several ways to install MIUI 13 on the Redmi Note 8T. The most common method is to use ports from other devices or custom builds. However, before starting any manipulations, you must unlock the bootloader through the official Mi Unlock Tool.
The unlocking process requires a device-based Mi Account and a 7 to 168-hour wait, and once authorized, you can install custom Recovery, such as TWRP, which allows you to flash modified system images, and it is through TWRP that enthusiast-created MIUI 13 ports are installed.
There are two main types of assemblies available for installation:
- 🔹 Ports from other devices are firmware taken from Xiaomi, which have similar hardware, and adapted to work on Note. 8T. They often contain camera or sound bugs.
- 🔹 Castomy ROM base MIUI 13 are reassembled systems that cut out unnecessary services and optimize for old hardware, and they are more stable, but they may lose some of the proprietary features.
- 🔹 GSI (Generic System Image: Universal Android images that you can pop on top of a shell, a method that is difficult for beginners and often leads to unstable work.
It is important to understand that installing any of these versions will void the warranty (although this is no longer relevant for a 2019 device) and reset all data. Be sure to create a full backup before starting the procedure through Settings → Advanced Settings → Copy and Restore.
☑️ Firmware preparation
Comparative table: MIUI 12 vs MIUI 13 (Port)
So that you can weigh the pros and cons before installing the unofficial firmware, we have prepared a comparative analysis, based on reports from users who installed MIUI 13 ports on the Redmi Note 8T through the developer forums.
| Parameter | MIUI 12 (Official) | MIUI 13 (Unofficial Port) |
|---|---|---|
| Stability of work | Tall, time-tested | Medium, possible departures of applications |
| Autonomy | Optimized for iron | Reduced due to new background processes |
| Security | Security patches through 2022 | Depends on the date of port assembly |
| Camera. | Quality of staff, all modes are working | Possible problems with zoom and night mode |
| Interface. | Standard MIUI 12 | New widgets, improved animation |
As the table shows, switching to MIUI 13 brings trade-offs: You get fresh visual style and new widgets, but you can lose performance and battery life. For everyday use in 2026-2026, a stable MIUI 12 often turns out to be a smarter choice, unless you're annoyed by the specific limitations of the older version.
If you decide to install, look for builds marked "Stable" or "Daily Driver" on reputable forums. Avoid alpha and beta versions, as they are exclusively for testers and may contain critical errors.
Risks and Possible Problems in Updating
Installing unofficial software is always risky. The most common scenario is a bootloop (cyclical reboot) where the phone gets stuck on the Mi or Redmi logo, which is due to the conflict of the old system files with the new firmware if the Wipe Data/Factory Reset partitions have not been fully cleaned.
Another major problem is the loss of functionality of communication modules. Since MIUI 13 uses new modem protocols, VoLTE, Wi-Fi Calling, or even network signal loss can occur on ports for the Redmi Note 8T, and it is often impossible to restore modem operation without flashing the stock image.
⚠️ Note: When installing custom firmware, banking applications and Google Pay cease to work due to a violation of the integrity of the system (SafetyNet/Play Integrity API). The circumvention requires additional manipulation of root rights and Magisk modules, further reducing data security.
You should also consider the risk of "bricking" when interrupting the recording process, if the battery sits down or shuts down during the firmware on Fastboot. USB-cable, the device can go into mode EDL (Exiting this mode on MediaTek processors often requires paid accounts from authorized service centers, as standard unlocking methods may not work.
💡
Always check the checksum (MD5 or SHA256) of the downloaded firmware file before installing it. If the hash does not match the developer's website, the file is corrupted and its use will lead to errors.
