How to reset or restore a Quantum Q20

How to reset or restore a Quantum Q20

Last update: December 3, 2025 by

If your Quantum Q20 smartphone is running very slowly, hanging, you want to bypass the screen lock, or you have a full memory and want to erase everything, or you want to sell or give it away and want to ensure that nobody can access your files and passwords, you can do a factory reset to restore it to its original state like the first day.

In the following steps we explain how to format the Quantum Q20 to erase all your information and make it totally clean as it came out of the store.

Before doing a factory reset, we recommend deleting all the accounts on the device, specifically it is useful to unlink the Google account if you are going to sell, donate, or give away your Q20. This will avoid problems for the new user, as some newer devices include a functionality called FRP (Factory Reset Protection) that requires the same Google account or PIN code with which the Quantum Q20 was initially configured when factory resetting a device.

Keep in mind that a reset or return to the factory state on a mobile/cell phone deletes all its content, so make a backup of your data before doing it if you don't want to lose everything.In case you do not want to erase the data from the device, you can try to restart the Quantum Q20..

There are two ways to do a reset on a Quantum Q20 one through the mobile options and another more complete from the recovery mode.
