here is repacked FI27 kernel with my recovery and some init.rc edits.
SD card read speed.
Custom boot animation support
AGAT_FI27_repack.tar flash with ODIN or Mobile ODIN
AGAT_FI27_repack.zip flash in recovery.
Did some edits in initramfs and run some tests.
Moved couple of apps to sd. After 5 reboots apps still working.
Tried to connect to pc in recovery.
ADB shell - works
Mount USB storage - works.
Hopefully it will work for all of you as well.
Enjoy the kernel.
