Samsung Hard Brick Fix Being Worked
If you own a Samsung Exynos 4210-based device, including but not limited to the Galaxy Note GT-N7000, Epic 4G Touch, AT&T Galaxy SII, or the Korean SHW-M250S/K/L, then you need to read this article to make sure you do not end up in a Hard Brick state. Thanks to developer Chainfire on XDA, an app was developed to help determine if your device is at risk for brick. Who the hell wants a $600-$700 brick, what a waste of out hard-earned money.
XDA Elite team member Codeworkx posted the following on Google+:
We’ve contacted Samsung about the problem where performing a mmc erase could hardbrick your phone (i9100, i9100g, n7000, m250 – MAG4FA, VYL00M, and KYL00M with firmware revision 0×19 // T989 and I727 with fw rev 0×12) if it’s having a faulty emmc chip.

They’re working as hard as possible on a clean solution which will be ready soon.
Please be patient and try to not flash any leaked kernels or kernels based on sources where MMC_CAP_ERASE is present.
Thankfully, Samsung is aware of the issue and is working diligently to rectify it. They have publicly responded indicating that they will be pushing a simple software update to address the issue. Furthermore, Samsung went on to say that they are providing detailed information to local developers so they can fix the builds (ROMS) that are currently being worked.
