Root Enable JIT / Disable JIT

[IzelTokatl]

For those of you looking to either Enable JIT or Disable JIT on a ROM that has JIT built in (or you've manually flashed it) and decided you wanted to remove it. I had a little trouble searching so I figured i'd post it with a simple logical subject line for future searching.


In the /System Directory you need to fine the file called:
build.prop

then edit the line:
dalvik.vm.execution-mode=int:jit

to say:
dalvik.vm.execution-mode=int:fast

and revsere it to enable it back (fast to jit)



You can do this a few ways.

1. use a file explorer on your phone (such as ES File Explorer) or Root Explorer find the direcotry /system make sure the drive is R/W (read/write).

Open the file, build.prop, then scroll down to the bottom of the file and it should be within the bottom 5 lines and do as stated above.

2. use adb commands, connect phone via USB.
adb remount
abd pull /system/build.prop build.prop

on your PC find this in your c:\"androidsdkdirecotryhere"\tools\ and edit with your favorite text editor.

then save the file, and go back to your cmd window and type
adb remount
abd pull /system/build.prop build.prop

if the lib files arent there though this wont do anything. itd be better to use the patches, i have jit on.off patches for ww and ss, they may/may not work with other roms, and zachxtra has on/off patches for his too.

How do you make your phone R/W? It won't let me open the build.prop file.

If you use any CM7 ROM, you dont need to mess with the Build Prop file anymore. It's a setting in the CyanogenMod Settings section.

use something like:
[ROM][4/11/2011] GSB v2.8 | GingerBread 2.3.3 [CM7.0.0 NIGHTLY] - xda-developers

its VERY good.

I'm using Nonsensikal v16.1 and read that if I disable JIT it would run smoother. Is that not the case and is it not worth messing with?

Nonsensikal is a cm6 ROM, so from the home screen try doing the following:
menu>settings>cyanogen settings>performance>uncheck the box for JIT.

Should I update to GingerBread 2.3.3??

 

[metlcat]

It's all preference. I like Gingerbread, but others don't. I'd suggest reading the GSB thread on this forum to see what people have said about it.

 

[IzelTokatl]

should you or shouldn't you. Thats up to you. But, it doesn't hurt to try. Just do a nandbackup of your current setup.


after that jump in the pool and see if you like it, if you dont, just wipe, and nandrestore and you only lost about an hour of your time.

I came from Nonsensikal to GSB and it seems smoother to me.

Yes, yes you should. Its pure awesomness.
