and it's not really a big deal unless it's preventing the device from booting, or unless you want to accept an OTA i'm thinking.
but depending on the device samsung has a tool called odin to
flash stock firmware to these devices.
at this point... unless it's hurting functionality i'd ignore it.
but if I wanted to try a newest OTA update and was blocked by this.
I'd find the correct firmware at sam mobile for the device, flash it back to stock with odin, and then update it on OTA.
This may stop you from rooting it again for awhile tho, the OTA i mean.
hope this helps
