Hi, thanks for the solid advice. Worked out great! Now I have my overclock functions again! Hv was strange. I was using stock rom with abyss, then flashed rocket 22. Few days later I wanted to flash rocket 23 and discovered my cwm had turned to red pill. Then, after flashing 23, I noticed the status showed,'flashing kernel'. Then realised my kernel changed to Francisco and I had lost oc capabilities.
Anyway, long story short, it seems rocket 23 flashes a prepackedkernel. Those who want to change the kernel again can use odin directly.
Can't thank u guys enough for the advice!
