Help installing stock ROM over custom ROM

[gullyonethatsme]

hi, i recently installed cm12.1 on my galaxy s2 plus (i9105p)
unfortunatly i messed up my backup i made before installing CM.
i want to reinstall my stock rom 4.2.2 (German non branded)
do i just need to install ROM by ODEN?
will it work?
at this time i have CWM recovery and CM12.1.
please reply.

Install stock firmware that matches your CSC via Odin, it will bring you back to stock with no root.
