So my script may work well but I didn't wait to see . Anyway I need some script that loads before opptimizer because changing freq and voltage too fast with SR2 on make my system crash .

yes , I've tried with -u root too but same result .

Is there no way to run a script immediately on startup, i e without the 2-5 minute wait?

adding the .conf to /etc/init/ instead with signing of refhashlist might do it i think...

by simply running 'perl refhashlist.pl' right? I'll give it a try. Thanks!

Adding anything to /etc/init/ will cause an immediate reboot.
'perl refhashlist.pl' doesn't work either so I guess I'm doing this all wrong...

That might happen if you use things that rely on other things not yet initialized. Although a more likely outcome is that it simply won't do anything. Try experimenting with the order of execution. /etc/event.d is also a good place but the scripts there have to adhere to a strict format otherwise they won't run. Look at some existing ones (as well as a copious use of Google) for an inspiration.

This is probably not the best solution, but if you are in patched open mode then you can add your commands to /etc/init.d/rcS.

In protected mode using inception you'd need to update refhashlist or aegis will lock the file and malf your phone so I don't recommend trying that unless you know what you are doing.

Also if you are in patched open mode you might investigate doing your own startup script in /etc/init.d (i suppose it's not allowed in normal mode, correct me if I'm wrong.)
