Data is the priority
Repeated failed storage devices, corrupted files or uncertain backups are reasons to avoid experimentation.
Hardware damage changes the problem
Swollen batteries, liquid damage, burning smells, overheating or damaged power components require appropriate service.
Account lockout needs official recovery
Do not keep guessing passwords or bypassing security controls when a service provides an account-recovery process.
Time has value
If the problem is blocking school, work or important communication, professional or manufacturer support can be more efficient than endless trial and error.
General consumer technology information only. Interfaces and menu names change. Before resets, reinstalls, storage changes or other major actions, verify that important data is backed up and use current manufacturer/service-provider instructions.
