DO NOT FLASH OR WIPE USING ANY ICS REPACK
The list of “known safe” kernels is below in this post – there are currently two known-safe ICS kernels, but only two.
These kernels are fundamentally dangerous. Samsung introduced some sort of bug in the eMMC driver that can permanently damage the eMMC flash storage of the phone. This leads to unusable partitions at best, and at worst a hardbricked device. The nature of the failure is so severe that the usual method for hardbrick recovery (JTAG) is unable to recover devices damaged in this manner.
Kernels that have been confirmed affected are:
All ICS leaks for the Samsung Epic 4G Touch (SPH-D710)
All ICS leaks for the Samsung Galaxy Note (GT-N7000)
