Xiaomi Redmi Note 8 is one of the most popular smartphones in the budget segment, but even it eventually begins to slow down, glitch or require complete cleaning before selling. Formatting (reset to factory settings) solves most software problems, but the wrong actions can turn the phone into a βbrick.β In this guide, three official reset methods, nuances of data retention and unique errors that are characteristic of the Redmi Note 8 with MIUI 12-14 firmware.
It's important to understand the difference between soft and hard resets: the first one deletes user data through settings, but saves system files; the second one (via Recovery or Fastboot) reinstalls the firmware completely, which is true if the phone is not turned on or infected with viruses. We'll look at all the options, including hidden MIUI features that are not written in the standard instructions.
Preparation for formatting: what to do before resetting
Even if you format the Redmi Note 8 due to critical errors, donβt miss this step β it will save you from losing important data and problems with your Mi Account. About 30% of users experience a phone lock after a reset due to a tied Xiaomi account.

If you forgot the password from Mi Account, restore it to account.xiaomi.com - after resetting, it will be more difficult to do this due to the link to the IMEI of the phone.
The third is to check the battery power. Recovery formatting can take up to 15 minutes, and if the phone runs out during the operation, there's a high risk of damage to the system partition, which will require a PC flashing.
