Exactly as I expected it to look. Good.
If you do the same modification to the boot script? Or rather, change it to this so that we also catch any errors (possibly):
LOG=/cache/mhpc_test.log ls -l /data/adb/mhpc > $LOG 2>&1 echo "" >> $LOG 2>&1 getprop >> $LOG 2>&1
Please can you tell me what do i have to do exactly? I don't understand your last comman?
