If I'm able to fix the boot error, would I be able to use mobile odin or super SU to unroot it?
Either way any other suggestions for getting past the splash screen?
What I've tried exactly is:
-boot into CWM recovery
-wipe data/factory reset
-wipe cache partition
-wipe dalvik cache
-install ROM from zip
-reboot
custom ROMS install ok but give me the boot error
stock roms don't install at all

And thanks for the help i do appreciate it
