Gmail Account Recovery Help

I’m locked out of my Gmail and every built-in recovery prompt dead-ends. Google keeps asking for a backup email or phone that no longer works, so the standard account-recovery form gets me nowhere.

Here’s what you need to know:
• Issue: I can’t access any of the recovery options Google presents.
• Tried already: Completed Google’s recovery form multiple times with creation dates, last passwords, etc.
• Sticking point: “Recovery email/phone not working” message prevents verification.

I need someone who truly understands Google’s security flow—whether that’s advanced use of the recovery form, alternate verification data, or an escalation path—and can walk me through (or perform) the steps that will get the mailbox reopened without data loss or policy violations.

Deliverables:
• A reliable, step-by-step method—or direct intervention—that restores full access to the account.
• Confirmation that existing emails, contacts, and 2-factor settings remain intact.
• A concise summary of actions taken for my future reference.

If you’ve rescued Gmail accounts in similar situations, please let me know what information you’ll require from me and how soon you can begin.
