I'm having my own problem with Supercharger.
I'm using CM 7.1.5 and SuperCharger v6u8 (other other versions are now doing the same). It was working previously, but something must have happened and I'm not in the mood to flash my phone from scratch all over again (which brings me to another question - but I'll start a new thread for that).
Currently, whatever I choose on SuperCharger, it's giving me "sed: write error" and I've tried restoring (UnSuperCharging), but the error persist during that process as well. I don't know what's causing this, it's as if it can't write to the location or something, so I don't know what to do now. Help?
On a side note: does SuperCharger's settings persist on CM7 after a boot.
