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.

Sorry for my weak English。
In order to improve the sound ,I write a script.
as below,the script doesn't work.
Can you tell me,what's wrong in the script?

These are different usb modes you can force from a adb shell (needs root)
This is just a fyi for information.

cdc_ether
Hi I am trying to connect a cdc_ether device into the LG Nexus5 usb port. I have cross compiled kernel for 3.4.0 hammerhead for this devices and enabled the cdc_ether module on it. But when I looked at the /sys/devices/virtual/android_usb/android0/f_cdc_ethernet/on, the f_cdc_ethernet directory doesnt exist. Does that mean the kernel was compiled wrong?
Finally got a new battery after over a year of not using my Droid 4.
Flashed latest CM13 nightly, 1.4ghz OC. Everything seems slow.
My 512mb ram single core $19 cheapo runs smoother.
Anything I do has a half-second or so delay, clean install with nothing running in the background.
Ideally I would just go back to some minimal 2.3.7 ROM, but compatiblity for new programs is getting iffy.
So, as of 2016, what has the smoothest ROM to do date been?

I'm running very, very debloated, overclocked stock JB 4.1.2 with Greenify and ram manager and it works pretty well. Even most of new games and emulators rund good.
Cyanogenmod 11 is quite good. One thing I noticed is that the virtual ROM slots are extremely slow, due to the loopback devices.
One way to go is to install the ROM to the virtual ROM slots to test if they are working correctly and then install it into stock slot for real use.
Up, same question here
I use cm11 or cm12 (i find cm13 extremely slow) But with the following tweaks made from my daily experience feel free to try it

Thank you man, this script made my droid 4 a whole lot more responsive and it does not reboot every few hours anymore.
Quite a few commands in that script don't work, probably due to different paths (sio plus as io scheduler and stock rom boot slot), but those that work, really seem to help a lot.
Oh and you should update the comment in that script about the zram size.

Was testing on different Kernels that's why the paths are wrong.. Please replace the sio plus with cfq or bfq (i forgot to change that)
I am glad that those tweaks help you
Regards john
What about this one? Mentor's ROM http://forum.xda-developers.com/showthread.php?t=2122709
That's what I found on my used Droid 4... should I give it a try?

why replace sio plus? I used bfq before, but when i googled for sio plus i only found people saying that sio plus was the best of them all.

If your kernel support sio plus, of course use it.. else cfq or bfq is a good alternative

What am I supposed to do with these lines? And can somebody please explain what they are doing specifically?
I was trying to find a way to enable zram to cope with the small amount of memory. swap ram is an alternative, but i heard zram is faster and not stressing the storage like swap ram would.
