Compatibility check and device preparation
The first step before you start any action is to accurately determine the current version of the software and the regional affiliation of your device.The Redmi 8 smartphone (codenamed olive for the global version or olivein for the Indian version) could come with different starting versions of MIUI.

The critical step is to free up space in the internal storage. The system update file can weigh from 2 to 4 gigabytes, but successful unpacking and installation of system components requires a memory reserve that exceeds the size of the package itself by 2-3 times. If the free space ends, the process can be interrupted at the verification stage, which will lead to a boot error.
⚠️ Warning: Make sure the battery is at least 60% battery power before installation. interruption of the firmware process due to battery discharge can cause damage to the boot partition and inability to start the system.
If the device has two-factor authorization or Find the Device feature enabled, make sure you remember the Mi Account password. Once the settings are updated or reset, the system may request a reauthorization, and locking at the activation stage will be an unpleasant surprise.

At this point, the phone can noticeably heat up, which is normal physical process with active operation of the processor and memory module.

- 🔋 Connect the device to the original charger during the entire procedure.
- 🚫 Do not use your smartphone actively during the installation of updates, so as not to disrupt the file recording process.
In some cases, the check button may not show updates, although servers already have them, and this is due to the incremental deployment algorithms. If you are sure that Android 11 has already been released for your model (Redmi 8), but the OTA is silent, you can try changing the region in the settings (Settings → Additional settings → Region) to the country where the update came out earlier (for example, India or the Global version), and repeat the check.
