Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
That recovery code system is very misleadig.. Here is the issue, when you go through the reset password, you can enter all the information it asks you for intentionally wrong, and it would still send you a " recovery code" to your email.
Thats not a password ***** code, its only a code to verify you can access that email.
Now, if we are going to recover your account, I need to ask you a few questions.. When is the last time you cou ld access your gmail account?
Prior to losing the password, had you ever accessed the account on your home pc or mac?
Do you still have the old phone?
And do you have a windows pc or a mac available you can use?
