Root Tweaks Script for Stylo

[Updated 9/6/15]

Works for both cm and stock.

I am not responsible if:
  • Your house blows up or your kitten dies.
  • If you had a super important meeting and your alarm just didn't go off.
  • Your phone mysteriously catches fire.
  • You didn't follow directions.
  • You spontaneously combust.

So.. What is it?

It's a simple script that automatically sets governor settings, read ahead to 2048, and scheduler to deadline. Also enables ZRAM of 512mb

The main reason I created it is it sets freq_min to 200mhz instead of 800mhz.

What are the benefits of this?
It scales better according to load.
Potentially better battery life.
Solves a major heat problem on the Leon, not seen on the GStylo
Idles at 200mhz half the time it runs 1.2ghz


How do I use it?
  1. Download HERE
  2. Use file explorer and go to /system
  3. Create a folder called "su.d"
  4. Give folder rwx-rx-rx permissions
  5. Place file in folder.
  6. Give file rwx-rx-rx permissions
  7. Profit!

Code: 
 Changelog:
[*] V1.4 - Added su.d support for both stock and cm. Added Zram of 512mb. Added support for GStylo. Merged stock and cm scripts back.


Enjoy

With the addition of ZRAM you should now be able to cache the entire 20 background apps allowable by the system, which means faster app loading & performance in general.
I also observed that recent apps does not need to be cleared to reduce lag anymore.
 
If you do restore your phone to proper working condition adb pull /system/etc/init.qcom.post_boot.sh please so i may look.
 
If you can connect via adb push a blank file called CPU.sh to sdcard (adb push CPU.sh /sdcard)
Then (adb shell su
dd if=/sdcard/cpu.sh of=/system/su.d/cpu.sh)
And that should fix it. If not you'll have to use the exact same method in download mode. Send command doesn't seem to like rm -rf

i got
hokage_6th@Asus-X551MA:~/Downloads$ dd if=/sdcard/cpu.sh of=/system/su.d/cpu.sh
dd: failed to open ‘/sdcard/cpu.sh’: No such file or directory
 
Have to use external if in download mode. Otherwise you need to create the blank file in the root of your internal.
I think the path is /storage/external_SD or /storage/sdcard1 for cm for sd

well i unbricked it but I’m still having a hard time figuring out how....well now I’m unrooted and I’m gonna have to figure out my own root process but in Ubuntu 15.04 wish me luck

Sorry about that, I should have checked the link first. The problem is media fire displayed the script but when you saved it, it saved a bunch of html as well. That's what bootlooped you. I updated the link again to something that shouldn't 404.

okay so this is what i get when opening the script in Ubuntu

does that ^^^^ look correct?
