After reading some threads here I`m not sure what options I have.
Software
get an SCBO file after giving my hash at the password screen, ctrl - alt - command - shift - s gives it.
Where can I get it? some says a chat with an Apple Tech Provider, but from my site Apple Support only gives me a trip to a near Apple Store, 4 hours car ride. Must I value the travel time and go to a paid site? are they reliably?
Are there any other ways?
Hardware.
To flash the chip don't seems ok for my expertise, also I think on my Macbook Pro is hard to get to the chip.
Then there are the Brute Force attacks, that may be more near to me, I also have a Raspberry but do they work on iCloud pin issues or will serve with only firmware password one? Whats the best tutorial on that? ghostlyhaks.com/forum/macbook/480-2015-macbook-air-unlocking-w-o-efi-flash-success seems promising, i also have used rEFInd before to dual boot it.
I don´t know why it got stuck on the password screen no matter the keys. I think that if nothing changed on the startup screen it must startup as usual and get to users login, so something must have been changed there, Are there a way to just bypass it to get a nvram reset? or ensure the startup disk is the internal one? If I remove the SSD and try to boot without it will improve things?
Lots of noob questions, sorry. And thanks in advance for any help.

Will wait for someone used to the brute force attack to clarify if that methods work on a firmware password, not iCloud PIN.
