Help, longtime Member here, Cyber16

HELP!
I am a long time member, tried to log in but problems, then tried to have password reset and it returned address failed

Nonetheless,
Its been awhile since I have done some of these.
I have five early 2015 11" MacBook air that came out of a private school, they are damaged but plan to rebuild a few.

Years ago a simple $SVS search would be followed by several lines until you reached the ff ff
I would just ff ff ff out everything until then and the efi password would be cleared.

Will someone look at this dump, I took 5 dumps, and they all match md5sum

But it appears something has changed with what follows the $SVS
Its a long ways down until you reach the next ff ff ff

Then I was reading that everything must be cleared between the two $SVS entries?
That can't be right, thats a lot of code.
 A screen shot of what is now being ff ff out would be helpful. Can someone clean this dump?
Can I even upload a bin as a guest? Not seeing the upload option

I figured it out, but I did trash one and I will need to change SN one one of the other dumps to write to this trashed one, yes they are the same models. know to re-learn the SN location
Could still use a little help and also help with my account, it would be nice to be able to login under my user name cyber16
