Thank you, i was just about to star a thread on this because i'm having the same problem.

A quick breakdown.

from "Stock" to "Titans Kernels"
Started off on v42 - Overclock fine

Updated to v44 by accident (Selected Update All) - Never Checked OC'ing

Updated to v46 - No OCing it acts as if its a stock kernel

Went back to v42 - No OC (Stock look)

By the way all these times the Kernel was updated/downgraded the phone was restarted and the charger was not plugged in. Is pulling the b82ry out vital? I just remembered someone saying that...

Went to stock via Deinstall kernel.

Then back to v42 - No OC'ing.

So now I'm at v46 again - No OC

Another problem I have bumped into is.

When I boot into Nitdroid now after going through all those kernel stages it no longer is able to connect to APN's and show my network (T-Mobile UK)??

Something has happend and I'm not 100% on this.

Any ideas help
