Have a client's rMBP from Late 2013, no liquid damage or physical damage.
Has an SSD, so failing HDD is just about out of the question.
Ran Apple's "Extended" Diagnostics via CMD+D on bootup, passed everything (minus battery, but that's expected).
Basically, it will lock up about once every...15-30 seconds?
Unknown amount of time, I could be doing nothing and it locks up.
It's been reinstalled with El Capitan, Mountain Lion, Mavericks, etc.
I know it's not a hardware issue because it will work just fine (as it's supposed to) when booted into "Safe Mode."
Searched around, found that this was a very big widespread issue, Apple released an EFI update which was supposed to solve the issue.

Computer has:
Boot ROM Version: MBP111.0138.B16
SMC Version: 2.16f68
Obviously, laptop is well out of warranty, I want to see if I can do anything before deeming it a logic board.
Thoughts?
I tried putting it back on to OS X Mavericks, the closest copy I could get was 10.9.5 which was supposed to have the EFI update built in, and then the Apple installers won't let me overwrite the EFI update.
Can I reflash the EFI?
