The list in order i mentioned on rom toolbox works it really works.
Short version
-Save backup in ktweaker wkth apply immediately at boot
-force stop, clear rom toolbox data
-enter rom toolbox, kernel tweaks, governor tunables, press nothing here but apply at boot
-back out
Reboot phone normally
Watch for super user messages
-ktweaker and all will apply
-ktweaker message says applied at boot
-cpu load goes to idle
-5-15secs later rom toolbox says settings applied
-enter ktweaker no message should be shown.
This has worked since November for me.
-it wont work if up, up htpg, down, down htpg are not different values atleast 1 away from each other. Plus up and up never can be below any down or down thresholds and opposite down thresholds can never be above the up thresholds.
Stick to this type of restrictions on tunables and if having trouble on the settings mismatch the rom toolbox method will work.
Castlebravo interesting on the files you mentioned. You can add a line or two to initd file any there added in and echo the values to the files at boot you want. You can use the initd in OP as a template, replace the values you want and change the file fplder location and the initd can be used as a template for whatever your needs were like this. Using the echo command would make those files say the value you want when the initd script launched at boot.
