So I have rooted my Hero and installed nfinitefx45's stock ROM. Also, I flashed the JIT included in nfinitefx45's ROM thread and also the "Darchstar's Overclocked Undervolted kernel for senseUI roms vUV 2" 710 MHz kernel. I will be flashing a custom lockscreen soon as well. My question is, how do I remove one of the extra features I flashed on top of the custom ROM? For example, what if I want to remove the 710 MHz kernel, or remove the custom lockscreen? I did do Nandroid backups before flashing everything, but is that the only way to remove them?
