Personally having problems getting it to run at boot even with rom manager scripter, but my bionic gets rebooted maybe once weekly and it takes about 2 seconds to run both of the applicable scripts. I'm running mine in mot_hotplug with 1200 mhz max and 600 mhz min on 905 and its crazy stable with better than stock 902 battery life.
I followed exactly what you did on the video, created the script and all, and after the first execution I was able to set 1.2 just fine. Maybe five minutes later though, I checked it again, and it was back on 1.0/0.3. I ran my script again, which took about two minutes, and when it cleared I was still on 1.0. I didn't make any changes during that time, any ideas?
