late 2013 13" Macbook pro firmware password HELP

[cyber16]

I have done many of these over several years, But its been some time since the last time.

Normally I dump the rom 3-5 times and compare before anything else
Which I do have clean dumps, then I would search for $SVS and ff ff out every thing that follows that including the $SVS all the way down to the next large series of ff ff

Upon 1st boot I will zap pram a few times, Password IS GONE
yet the laptop is acting strange, powers off all of a sudden for no apparent reason.
Besides that, the trackpad clicker does not work in internet recovery and other odd things.
Maybe I remove part of the config? IDK
For some reason it seemed like I had to ff out much more than I recall doing in the past, maybe I took too much out.
Nonetheless, can someone just remove the password from this LOCKED dump, Once done I will compare with my work to see where I screwed up.

Thank you.

Error: Image size (8388672 B) doesn't match the expected size (8388608 B)

No size error if I write back the original locked dump

No the laptop appeared to work just fine there is no liquid damage or anything like that. It would actually boot right into OS.

I've noticed it's even got a power on issue now it's intermittent trying to get it to power on just to do a read and write with MY diy unlocked bin, with these particular MacBook Pros I learned a while ago you're powered on until you hear the chime and then press and hold the power button and do your reading write at that time.

Like I said I check summed all the dumps to make sure they were identical/clean

Model A1502
ECM 2678
SN C02LGAEHFGYY
i5 2.4GHz

Actual logic board model number appears to be on the other side of the board sandwiched under the keyboard.

I am attaching a locked bin
As well as my DIY unlock that is causing a bunch of issues.

THANK YOU SIR
That appears as it resolved issue, now I need to do some comparison to figure out what the heck I did wrong. I've unlocked many over the years I came from ghostlyhaks I've had a few of their clips use on a raspberry PI 3 over all these years.
It just appeared that there was an awful lot of data following that $SVS until the next zeroed out area of size.
