PS. I've discovered in the last year that PIN + fingerprint beats pattern by far.

I would try use open-source script/software to unlock the smartphone if it has old version of Android which have vulnerability against physical attack, but good thing you managed to make a copy of your data.

What I learned is always write down your pk, 2fa recovery and put it in a safe place. As long as you still have an acess to your gmail or any cloud storage where you saved it. Please do have a double backup.

I successfully recover two of my gmail account using the verification method it really takes 3 to 7 day, the trick is to remember the last password you had, and the year you created the account, to get a good chance include the exact date, that is why whenever I create a new account, the first thing that I do is to send email on one of my other email, with all the information related to the email I just created.
You must think ahead, and always think of the worst case scenario.

Damn it, when I read this I decided to print out all my passwords from the LastPasss manager and keep them on paper in a locked drawer. So much for the new digital age and cloud storage! LOL!

You said you stored your info on Google Drive, Dropbox and you will be fucked again. I hope you won't but you could clear all files on Google Drive, Dropbox if they are backup of your passwords, 2FA.

Too much cloud security backfire in your story. Your are in loop security for all your account and you will be in trouble in case one them is not functional because your password recovery is connected to other cloud account.

I believe you will solve it fast if you root your phone and used an app to remove/reset finger print pattern. Just unroot your phone and reset it once you access your Google. It will save you a lot of time and hassle.
