How do I get my phone back to normal from a failed root?

[msgreyxx]

white text on boot?

hi,

so i got a little brave and rooted my phone last night its a S4 GT-I9505, after rooting i flashed the clockwork mod recovery and thats all.

after awhile it made my phone a little glitchy "it randomly rebooted" so i downloaded the stock firmware and put it back on my phone, but i noticed that white text with information such as reboot mode and bootloader is being displayed when the phone starts up, before the s4 / samsung logo.

how do i remove this and just get my phone back to normal?


edit: why has my title been changed? i didnt say the root failed...
