Before carrying out a factory reset make sure all files are synced to the cloud, as the process will erase all content from your reMarkable. If you’ve synced with the cloud beforehand, all your data will return when you reconnect to the cloud after the factory reset.
If you need help connecting to the reMarkable cloud service, you can find a guide here. After the factory reset is done, the reMarkable will start up with the standard setup and onboarding procedures.
To perform a factory reset of your reMarkable paper tablet follow the below steps.
Go to Menu > Settings > General > Account (select account) > Factory reset.
Be advised that you can always use the USB web interface to transfer files between your tablet and your computer before performing a Factory reset.
