Re: [MOD][TWEAKS] ThunderBolt! v3.1.1 3/25/13 [Performance+Battery Life Mods & Tweaks

Hey Pika.. I enable the tweaks in system/etc/boltscripts. However, when I go to etc -> /system/etc/boltscripts none are enabled.

I thought these locations were the same...Should I enable tweaks in both locations?
[Android Software/Hacking General [Developers Only]] pikachu01:
What do you mean by "enable" and what do you mean by "none are enabled" in what sense?

Okay....When I say "enable" I mean click the skull & bones or gear symbol through Smanager.

Everything that is supposed to be enabled in this location, is:

However, when I goto the location that is circled in Red, none of the tweaks are enabled:

I'm using stock ROM XWLSJ and Siyah 6.0 beta 5. Using ThunderBolt! (with remount/TCPBuffer/zipalign running on startup with Script Manager) and screenstate_scaling + libsqlite 4.1JB.

Oh wait, I thought /etc is supposed to be soft linked to /system/etc. It might be a Script Manager bug that it's not detecting that correctly. Can you shoot an email to the developer to find out what's wrong?

You can ask him why the path from /etc and /system/etc differs as in scripts that are set to run as root/boot aren't the same when accessed through /system/etc. Isn't /etc a soft link to /system/etc?

pikachu01,

I recently switched to Carbon, a CM10.1/AOKP based 4.2.2 rom. I'm using Dorimanx kernel with MALI V2 drivers - and noticed it has a set of tweaks in STweaks called "CortexBrain", which apparently tweak the kernel in "CPU, memory, I/O and screen state" areas.

Are you familiar with them and know whether they conflict with Thunderbolt?

I'll need to see the implementation of the CortexBrain, though I'm pretty sure it'll conflict with most of ThunderBolt! given that ThunderBolt! tweaks CPU/memory, I/O and screen state.

I mean libsqlite addon. You mentioned that libsqlite causes boot hang. Which version did you use?

Also, I don't get what you're saying when you "wrote" /sys/module/lowmemorykiller/parameters/adj.

Can you provide the exact command that you're using?

There're some ROMs that fail to provide the proper build.prop string. You'll have to delete this line in updater_script:

ifelse(getprop("ro.build.version.release") == "4.2" || getprop("ro.build.version.release") == "4.2.1" || getprop("ro.build.version.release") == "4.2.2", ui_print(""), abort("You're applying this tweak on the wrong Android version!"));

[Android Software/Hacking General [Developers Only]] hoholee12:
isn't wait_for_fb_blah kernel related?

and your method doesnt move the process to background(creating a new thread shared by the same process doesnt mean it goes to background-_-),

instead simply allows the other process to continue first(new thread),

init might still be waiting for this process to finish. and you get a bootloop.

try exec command and see if its still doesnt help.
[Android Software/Hacking General [Developers Only]] pikachu01:
I've tried exec before. Exec doesn't send the process in the background. Instead it spawns another process that (if the init.d isn't parallel to boot up sequence, it will still wait for the process to be done).

And yes, wait_for_fb_* is a kernel issue. There are some Cyanogenmod kernels that doesn't support it. Just the action of doing

cat wait_for_fb_wake

OR

cat wait_for_fb_sleep

hangs the whole Android OS.

And one other thing, I'm not sure what the heck this code is:

if [ "$1" != BG ]; then
$0 BG & exit 0
fi

What the heck is "BG". It's not a Unix command nor BASH specific command.

Anything after the exec command is ignored as the old script process is discarded.

Can you please read more about BASH scripting before spewing nonsense?
[Android Software/Hacking General [Developers Only]] pikachu01:
Let me just englighten you on what BASH scripting is.

exec

will spawn a foreground process with a different PID discarding the old process. If you're using exec.

fork

will spawn a different process while keeping the parent object. It is still in the foreground.

method &

Runs the method in the background as the method is not called automatically until the method name is called, this is the cleanest way of running init.d scripts.

then have you tried only this?

exec >/dev/null 2>&1

---------- Post added at 07:11 PM ---------- Previous post was at 06:56 PM ----------

because if wait_for_fb_wake sends out wake, then wait_for_fb_sleep sends out nothing(not blank).

so the whole OS is waiting for it to send out something. all linux kernels have that "feature".
[Android Software/Hacking General [Developers Only]] pikachu01:
Oops, accidentally clicked the thanks button. Anyways, you can try doing this

busybox

in terminal emulator. See if you get an output.

That command basically does an exec sending the output to null and STDERR. Just doing an exec is the same thing.

If you already knew, then why did you make a mistake telling people the wrong stuff.

There's a famous quote for this:

The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

You keep misleading people with your half truths. If you don't know just say you don't know.
[Android Software/Hacking General [Developers Only]] pikachu01:
Another misleading piece of knowledge from an ignorant.

wait_for_fb_* is an interface to be used by scripts denoting whether the frame buffer is awake or sleep. In some Cyanogenmod ROMs particularly 7 and 9 has a problem parsing it due to didle code.

Edit: It does output awake/sleep for scripts to parse. However when you cat, it will hold the terminal until the wake/sleep event is done.
[Android Software/Hacking General [Developers Only]] hoholee12:

Spent 10minutes just to verify something from you as previously you keep insisting that people try something.
