Went through hell this evening after factory resetting my phone to find out that I needed to use my previous Google login to get back in. I had just changed my password which triggered a 72 hour lockout so I was unable to get back into my phone. I got online and researched how to get around this, only to find that Samsung had patched
After 5 hours of work I was finally able to break through the restriction and get back into my phone without having to use my Google login. I am currently working on a how-to with all of the files necessary to recover and will consider posting it.
I am not sure how many people out there may need this, but please let me know if you do.
[Update]
Just to be clear I spent hours trying to find a workaround to this issue and after being unsuccessful many times I finally found a method that worked. I really only know a small amount about flashing ROM's on phones so there are most likely steps that aren't necessary or easier ways of doing this workaround, but there was no way in hell I was going to re lock my phone to try again. And yes I know this technically isn't a "crack" more of a workaround, its just that it was 3am and I hadn't slept in almost 24hrs and I finally made it in, so I got a little excited.
