Step 1: Account Verification & Automated Recovery

Always prioritize Google's native cloud credential verification. If you have access to secondary 2FA recovery (SMS, Authenticator, or backup security keys), verify ownership through accounts.google.com/signin/recovery.

Native Google cloud recovery ensures that user cryptographic tokens and partition encryption remain uncorrupted. No flashing or partition modification is required if credentials can be recovered through account recovery channels.
