Safe mode on LG Optimus 2X
If your G2x is rooted, the easiest work-around would be deleting the Tasker's data from recovery.  Download and install Android SDK and LG's drivers for the G2x.  Reboot the G2x into recovery mode (preferably ClockworkMod), connect to PC, and in command prompt issue the following commands:


  cd C:\AndroidSDK\platform-tools\
  adb shell
  su
  rm -rf /data/data/net.dinglisch.android.taskerm
  reboot


This should remove all Tasker profiles, including the "bad" one.
