[DEV] Script for tweaks (version 1.02) 18-12-2010

ruigui · Dec 10, 2010

Here is a script i've made (had nothing to do, so...).
Phone must be rooted and have busybox installed.

What first menu looks like:

1 - enable/disable hardware acceleration
2 - enable/disable jit
3 - enable/disable stagefright player
4 - change heapsize

s - show status
r - revert to original configuration

q - quit (don't forget to reboot your phone!)
==================
enter your option:

Just copy the file to your sdcard. Then in a terminal emulator run:
su
cat /sdcard/tweaks > /data/tweaks
rm /sdcard/tweaks
cd /data/
./tweaks

If it doesn't run, type first:
chmod 755 /data/tweaks

Additional notes:
Script does not work if run from sdcard, must be in /data/ or /system/ (this one goes to allsalvati for testing)

---

If anything is wrong i will fix it, but only if you give me feedback

If you know any good tweaks, say it and i'll add them.

Please give me some feedback. I don't own the phone so i can't test.

what the script does?

The_ERROR · Dec 10, 2010

So script should be able to do:

enable/disable hw acceleration
enable/disable jit
enable/disable stagefright player
change heapsize

ruigui · Dec 10, 2010

Yes. For now it's what it does.
The ideia is to be able to enable/disable a certain tweak, without reflashing zips, and rewriting files in phone.
But i need some feedback to know if it is working. I can't test it.
It will only change values in /data/local.prop, nothing else.

The_ERROR · Dec 10, 2010

It seems that it is well written, so I will try that and let you know what's happened.

ruigui · Dec 10, 2010

Thanks for testing. I'm still waiting to have some money so i can buy this phone...
Meanwhile, i'm "playing" with ROMs and files. I'm not good at scripting, but i'm trying to learn while doing something useful.

How much did you increase the heap size?

I didn't increase it. Script shows this message:
"default=24, recommended=32"
"enter new heapsize value (1-64): "

You can enter any value between 1 and 64.

If you enter any other value, or a string, character, symbol... script will show this message:
"wrong value"
"please input a value between 1 and 64"

For those who don't feel like editing this themselves this is great. Thanks for releasing it for people to try out more tweaks on stock ROMs.

allsalvati · Dec 10, 2010

i'm trying to run this script and gives me the following message: ./tweaks: permission denied

Before anything i typed su, then chmod 777 and it gave me error.

ruigui · Dec 10, 2010

It should work be working...
Anyone else confirms this issue? Is this script running or not?
If it is working and there are more tweaks, i can easilly add them to the script.
If this is an isolated case, i really can't help. I don't own an android phone (yet), so i can't test....

allsalvati do you have busybox installed?

allsalvati · Dec 10, 2010

No, i don't.

ruigui · Dec 10, 2010

That may be your issue.

You must mount /system/ as read-write, then copy busybox binary to /system/xbin/, then run these commands in terminal emulator:

su
cd /system/xbin
/system/bin/chmod 755 busybox
./busybox --install -s /system/xbin

After that you can mount /system/ as read only again, and reboot your phone.

I don't know if there is another way to install it that is easier.

allsalvati · Dec 10, 2010

I downladed busybox installer from market and the app says that was installed. The. /tweaks gives me the same message.

How do i test if busybox was installed right?

ruigui · Dec 10, 2010

I found this:

That is a problem, you cannot chmod a script to executable on the SD card. (well some things can, but 99% no) the system is designed to prevent u executing scripts from an SD card

cp it to /system/xbin or /system/bin.

Or if u hate to see it in system', use /data/

THEN chmod it. should be fine to run

Try to copy the file to /data/ (so you don't mess with /system/), and then try to run it with:
cd /data/
chmod 777 tweaks
./tweaks

It should not need to be run as root

allsalvati · Dec 10, 2010

Moved to /data and worked.

I changed heap size to 32 and disabled hardware accelaration just to test.
With hw acc - 981 on Quadrant
Without - 820

So i think this is working.

Perhaps you should print the values so the user can see what is enabled or not before apply.

Thanks for your help

Can you test something for me?
Make sure you have hardware acceleration disabled, and reboot you phone.
Then open terminal and run:
getprop | grep hw (see what it outputs)
then run the script, enable hardware acceleration on it, but DON'T reboot your phone yet.
Then exit script, and run again:
getprop | grep hw
Has the value changed, or is it the same?
I need to know if the system assumes immediately any changes (although they may not be functional until reboot).
This is needed to work on your request.

I'll work on that and post an update after someone tries what i asked above.

Thanks for testing

EDIT: to test benchmarks, enable/disable jit. It gives greater differences in values

allsalvati · Dec 11, 2010

I tried what you say and both outputs are the same:

$getprop | grep hw
[debug.sf.hw]: [0]
[hw.keyboards.65537.devname]: [7k_handset]
[hw.keyboards.65540.devname]: [thunder_keypad]
[hw.keyboards.65541.devname]: [touch_mcs6000]
[hw.keyboards.65542.devname]: [atcmd_virtual_kbd]

Edit: Tested disabling JIT and it worked. Linpack Before 7.35 - After 4.3

ruigui · Dec 11, 2010

So i can't rely on getprop to check current values...
If anything is changed, getprop won't give the right output till reboot.
Damn... Script was almost updated. Now i must find a new way and redo this section.

Thanks for testing again

EDIT:
New version for download at first post. status menu added.
I think it's all ok.

heaven666 · Dec 11, 2010

It seems work fine on my phone. But I can't see the status. When I choose to see current status or status after reboot, the screen of my emulator returns too fast to the selection menu (show curent status or after reboot) and I can't see anything !
