A tough reset, also called a manufacturing unit reset, is a process that restores an digital system to its unique manufacturing unit settings. It erases all information, apps, and settings from the system, returning it to the state it was in when it first left the manufacturing unit.
Arduous resets are sometimes used to troubleshoot issues with a tool, reminiscent of freezing, crashing, or not responding. They will also be used to take away all private information from a tool earlier than promoting or giving it away.
