Xiaomi Redmi Note 9 (codename merlin) is still a popular smartphone, but many users face problems of regional firmware: lack of Google services, limited functionality or unstable work. MIUI It solves these problems, but it requires precision, unlike the standard one. OTA-Updates, manual firmware implies unlocking the bootloader, working with fastboot and the risk of turning the phone into a βbrickβ if you miss critical steps.
This guide will be suitable for Redmi Note 9 models (not to be confused with Note 9 Pro or Note 9S!) released for the markets of China (CN), India (IN) or Russia (RU). We will look at two proven methods: through Mi Flash Tool (for full flashing) and through TWRP receptacles (for power users).
Why you should switch to global firmware
Regional versions of MIUI are often stripped down in functionality, such as Chinese firmware (CN) lacks Google services, and Indian (IN) may not work with NFC or support for some languages. The global version (Global or EEA for Europe) suggests:
- π± Full support for Google Play Services and all apps from the Play Market without workarounds.
- π Many localizations, including Russian with correct system messaging translations.
- π Regular security updates (monthly patches from Xiaomi).
- π Optimized energy consumption and stability of operation (compared to custom firmware).
- π The ability to unlock the bootloader without additional manipulation (unlike the Chinese versions).
However, there are disadvantages: global firmware may contain more pre-installed applications (bloatware), and some functions (for example, IR-The remote blaster may work differently than in the regional versions, and it is also worth considering that after flashing all the data will be reset - be sure to make a backup copy!
Preparation for firmware: what to do before the start
Before you start installing, make sure all the preliminary steps are followed. Missing at least one item can lead to data loss or the inability to turn on the phone.

Special attention is paid to unlocking the bootloader. Xiaomi requires you to link your Mi Account to the device and wait 168 hours (7 days) after the first link. This step is mandatory - you can not install global firmware without the unlocked bootloader. If you have already unlocked the bootloader before, check the status of the command:

| Xiaomi.eu | merlin (custom) | Unofficial firmware without bloatware, with weekly updates. Requires an unlocked bootloader. | SourceForge |
