BuildUser ERROR after successful flash

Hello,

I have just attempted to remove the the firmware password on my Macbook Air (11" Early 2014). It does boot up just fine and I can reset NVRAM. However, I cannot boot into single user mode. When I try to it comes up with this screen: https://i.imgur.com/Cetc0wp.png (Sorry for quality) I do not understand what went wrong. here are the 3 reads I did and the modification that I made (mod.rom): http://www.mediafire.com/download/r498uqg73t3e99s/read%26mod.zip

Here are before and after pictures in my hex editor if that helps:

You deleted entire $SVS area. It is wrong. Flash attached file. This is your modified firmware with reconstructed SVS area.
But keep in mind, that may need to reinstall the system. Sometimes the full disk reinitialization required

I am confused, In his video/thread he replaced everything after $SVS. I am also trying to understand how to do this on my own. So, could you tell me how you got the file atached? How did you know what to replace and what not to?

I spent almost year to research that. I know how to read the data stored inside firmware and I understand its structure. It is not so hard, really I can even say that EFI password was set 2 times on your MBA.
And yes, thaGHO5T just delete data from SVS area on his video and it works. BUT time going and the firmware has changing and perhaps the logic of EFI boot has changing and other many things may be changed. Deleting the data from SVS area is wrong, IMHO. But again, current behavior of the MBA may be related with other things like disk damage or damage of data on it and may be something just can not be read or written... In this case you need to erase all partitions on the disk and install OS from scratch.
Inside the file attached SVS area just replaced by clean area from another dump. They are identical in structure but has the different information.
To clean up the password I use a script of course... Take a look here: www.ghostlyhaks.com/forum/macbook/164-flashrom-c-switch-command-usage

I solved the issue! I tried the bin you gave me token and it still came up with the same thing. I found out the issue was that I had Mac FileVault turned. After I turned it off and decrypted the drive it worked fine.

Thank you guys both for taking time to help me!

P.S.
Love the script and will be using it in the future!
