If the update is interrupted during the “Optimizing apps” phase, don’t force the phone to turn off – wait until the process is complete (it can take up to 30 minutes).

2. Damaged firmware or version conflict

Installing an unofficial firmware (e.g., Pixel Experience or LineageOS) without first unlocking the bootloader or violating instructions often results in “bricking.”

• 🔄 Reverse to an older version MIUI without data cleaning (wipe).
• 📦 Install firmware from another model (for example, the firmware Redmi Note 10 on the Redmi Note 10 Pro).
• 🔧 Use of Root Rights Patches (Magisk) with Errors.

Critical error: If a device is identified as an unknown device in Fastboot or is not recognized by the computer, this may indicate damage to the boot or system partition.

Hardware malfunctions

Physical damage can trigger a transition to Fastboot:
