Method 2: Hard Reset with Recovery Menu

Sometimes the system doesn't boot, the screen is locked because of an error, or the touch input doesn't respond, and in these cases, Recovery Mode comes to the rescue, a low-level environment that allows you to control the device even when the interface is not working.

To get into this menu on the Redmi Note 9, turn off the phone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power button, but keep the volume.

What to do if you forget your Google account or password

The situation when the user forgets the pattern lock, but wants to reset the phone, is one of the most common. Hard Reset through the volume buttons helps to remove the key itself, but activates FRP (Factory Reset Protection).

FRP is an Android security mechanism that requires you to enter a password from the last synced Google account after a reset, so that the thief who stole the phone can’t just reset it and use it again.

If you have forgotten your Google account password, try to reset your access via your computer or another phone at accounts.google.com. If you don't have access to your email, it gets complicated. You can't officially reset FRP without a password.

There are informal ways to bypass FRP through special utilities and vulnerabilities in the system, but they are constantly patched by Google and Xiaomi, and the use of such methods can be considered a violation of the terms of use of the software.

Also worth mentioning is the touchscreen issue: On some Redmi Note 9 models, after updating or resetting, the screen calibration may get lost, in which case calibration through an engineering menu or resetting will help.
