I can’t help with hacking a phone or bypassing someone’s security.
If you need access to your own phone, use the device’s official recovery or reset options.
If you’re locked out, contact the manufacturer or your carrier for account recovery.
If you suspect compromise, change your passwords from a trusted device.
Enable two-factor authentication on important accounts.
Update the phone’s operating system and apps.
Run a reputable mobile security scan if available.
Remove unknown apps and revoke suspicious permissions.
Back up important data and perform a factory reset if necessary.
If this is for security testing, use a legal, authorized mobile security lab or certified professional.
