I just make guide to enable Jit

Requirement:
eclair Rooted
Download this http://bit.ly/JiT-toggle

first use this command at adb

adb pull /system/build.prop

you can also manually use root expolrer to copy built.prop
edit the build.prop (im using notepad)

change this:
dalvik.vm.heapsize=32m
debug.sf.hw=1

added this at the end:
dalvik.vm.execution-mode=int:jit

save the changes..

after that extract http://bit.ly/JiT-toggle
at sdcard/JiT-toggle-0.1

and save the file
then do this steps

after that you must copy and overwrite the mod built.prop to folder
/sdcard/JiT-toggle-0.1/vmlibsv2

and the original build.prop to /sdcard/JiT-toggle-0.1/vmlibs_stock

then
1: enable JIT (in a termnial or adb shell)
cd adb
adb shell

su
cd /sdcard/JiT-toggle-0.1
sh enable_jit.sh

and your phone will reboot with JIT enable.

and if you want to disable jit effect just use this command

tribute for Zocker Tko

With jit, i can increase the value of quadrant score by 10 - 15 %

and linpack almost 3 times than normal


other

After


and look at cpu score (the blue one)

JIT refers to Just In Time compilation. Which is basically converting VM code into native code. Yes, it will definetly make your X8 MUCH faster.

Something isn't perfect with your solution.
I had enabled the jit by your script and my phone had been slower.
I disabled it and the phone stopped at the boot screen.
A had to reflash it.

Before you publish a solution be sure that it's working well!
What firmware you get the lib-s from?

Its works properly theres only a boost for game loading time or decoding videos
For rest the processor is good as it is
Dont blame the op if you brick or wreck your phone it works for others you must have done something wrong!

I know what I did. There was no problem.

I could enable it as well.
I changed some things in the system. Maybe one of them doesn't like it.

If you try to disable it, please let me know is it working or not.

Thanks.

I didn't want to blame anyone. Really sorry, if I was rude. :(


For a compensation I give you a taskbar theme (what I'm already using) ;)

You can change it by this way:
1. Extract the framework-res.apk from the zip to the root of your sdcard.
2. Be sure that the busybox is present on your phone!!
3. Save your framework-res:
Code:
adb pull /system/framework/framework-res.apk
4. Copy the new one to the /system/framework from your sd:
Code:
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system
busybox cp /sdcard/framework-res.apk /system/framework/framework-res.apk
I modified pulp's framework-res (from his X8.img) (2.1-RUS).

When you change it, the phone maybe freeze! You will see the new theme after a reset.
if you make something wrong, your phone will restart without any changes.


If you try it, please let me know how do you like it!
If you don't like it, you can put back the original framework-res.apk by the same way.

nice .. please upload default SE clock.apk thanks.:)

It is just the taskbar what I uploaded. Everything else will remain as before.


But if you haven't got the original SE Home screen app and the SE clock, I attached them.
(I prefer the mClock, because it is fully customizable. That's what you see on the screenshots. ;) )

Jit works very good on my phone. For those who have problems and lag after enabling jit i recommend to delete the contents of your /data/dalvik-cache folder using root explorer and immediately reboot after this. Phone will boot slower first time after the deleting of the dalvik cache because it will need time to rebuild it but after this your phone will definitely work better. I got quadrant result 513 and linpack 7.4 on my X8.
