Do I have to worry about downgrading custom roms from 4.3 to something earlier?
Like triggering something or bricking the device...?
1. Android 4.3 have new bootloader. You cant downgrade from android 4.3 (if u install ur firmware by OTA, ODIN or KIES) to something earlier.
2. The unique u can do for no update ur bootloader (before the Knox) is install one custom ROM by Custom Recovery
. The result will be android 4.3 with old bootloader (no void ur warranty: KNOX 0x0)
