Tweak init.d script prevents boot

Hello everyone!
I made this script for myself from stuff I found online. But when I put it into init.d the phone stops booting before the cyanogen logo comes up (on the second LG logo). I can't figure out why... However it works (the settings are applied) if I run it with adb once the phone is booted.
This is the script:
Code:

Thanks!

user.feature.lgdrm=false disable DRM Service, so you can not use the default phone ringtones and notifications but if you are planning to use your custom files without DRM then there are no problems.

Question Minimum CPU frequency

I try, through the Kernel Adjutor, to set the minimum frequency of the big / little cores, but they are reset. If I understand correctly, this is due to the "System Modes" setting in the "Battery" section. The maximum frequency can be lowered and maintained, but the minimum is reset each time. Is there a way to stop this behavior?

Probably not. Your only option is to use a custom ROM I think.

Solved with script
