[Q] Upgrade from rooted NB4 firmare to NF9? topic

Hi,

Looking for any information on upgrading from old rooted NB4 firmware to NF9. I know I need to use Odin but there aren't any clear guides out there with the information I'm looking for. They all seem to address upgrading from STOCK 4.4.2 to rooted NF9/NE6. Any help is appreciated!

Current firmware version running SlimKat: N900TUVUCNB4

Thanks
