Looks like I have crossed 700 :p JIT works well. Slowed down my phone for ~7-8 minutes. Worked fine after that.. 726
[XPERIA X10 General] ealax:
take a look on your battery consumption, I guess this will drain your battery quite fast

very average result, will be swapping over to a nexus one after my holz (making good use of the x10i camera ;)
[XPERIA X10 General] Astral07:
i installed JIT but i guess it didn't work, still 530 points

i copied the install.cmd and other files directly into the adb folder and ran it, it found my device and installed everything, in the end it restarted my phone but nothing's different??

and yes, i do have root, 2.1
[XPERIA X10 General] MarylandCookie:
I only managed to get 644 so how in the world did you get over 700 :confused:

Please... share :D

I guess it depends on what apps everyones removed/installed etc
[XPERIA X10 General] Contrarian:
So the X10 is faster than A desire running 2.1 ?
[XPERIA X10 General] Astral07:
Can you please explain everything you did to enable JIT? in steps please, and no matter if a step seems unimportant please include everything

i must be missing something, it just doesn't work on mine
[XPERIA X10 General] Siddy1200:

MarylandCookie, please explain the steps :)

My JIT installaiton didnt work, quadrant is still 545.

I just followed the instructions from the link provided by : zephyrix

1st thing to do is download the x10 1.6 One Click Root App version 1.08 by Ardf69 and install that on your phone.

2nd Run the app and select "unsecure shell" and exit app then follow the instructions from the above link. When done secure the shell again using the One Click Root app.

IF YOU GET A POPUP ON YOUR PHONE WHEN YOU CONNECT THE CABLE, SELECT CHARGE PHONE! Otherwise the process will not work fully!

[XPERIA X10 General] javagreen:
After installing it, I did not remove the dalvik cache *before* reboot. I just used root explorer to go to the data/dalvik-cache folder after the phone had booted and removed [deleted] everything in it.

Viola, I instantly got a "com.process.acore..." has stopped unexpectedly".. with a force close button. I clicked it and now have physically rebooted the phone... let's see what happens now. It's kinda stuck at the SE bootup Logo as we speak :o
[XPERIA X10 General] javagreen:
Okay it has rebooted now... but dayum is it S-L-O-W... like someone else said, it's probably building the caches... let me see if it runs into any errors .
[XPERIA X10 General] realunited123:
It got to be slow.. It is rebuilding Dalvik VM again so if it is not slow after going through the process then you are doing something wrong.
[XPERIA X10 General] javagreen:
Hmm, now that I think about it... it isn't too slow.. I mean the slowness went away within like 1 minute :/

Quadrant Standard benchmark result : 635

Does that mean JIT is in effect? is there anything I can do to increase it even further? Damn, i'm getting greedy here :p
[XPERIA X10 General] realunited123:
it will slow down again :p Yes it means JIT is effective.

can u link the other guides?
[XPERIA X10 General] Astral07:
man can you please link the app? and just to be sure we're on the same page, this is for 2.1 right?
[XPERIA X10 General] PheneoN:
Maybe someone who knows how to enable JIT on the X10 from A till Z, wants to make a separate topic with a small guide how to do so.

My knowlegde is not that big with using scripts, i know how to follow a guide, but the fact that it will brick your phone forever scares me. :S
[XPERIA X10 General] Astral07:
it doesn't even have to be a separate thread, i'd gladly follow it right from here :)
[XPERIA X10 General] dk2000zx:
+1 Totally Agreed
[XPERIA X10 General] zephyrix:
Probably because you didn't clear the cache.
[XPERIA X10 General] dk2000zx:
a nice guide "FOR NOOBS" would be nice please please please!!! I keep getting "permission denied" or "read only thingy".... on the automated installer

[XPERIA X10 General] tom0927:
after installing JIT, rebooting phone and killing all tasks/services, it's 656.
[XPERIA X10 General] Astral07:
man i hate to sound *****y but i don't believe none of you are willing to write a simple guide on exactly how you installed it...where's the sharing? ...
[XPERIA X10 General] tuxStyle:
There is at least one link in this thread to the tutorial.

I'm pretty sure because i followed the link and did it myself :P

Thing is ... is unstable.

My phone rebooted twice in last 5 hours.

I don't know if the libs from the other links are the same but if it crashes like this, is pretty useless...
[XPERIA X10 General] dk2000zx:
lol problem is idk whats ADB... idk how to access it...
[XPERIA X10 General] Astral07:
there's one link and it's not very helpful

if it's not a big deal then why not just copy paste the tutorial in your own words/steps, i don't see why that's such a problem?

i tried 10 times and failed...sorry for being such a noob but i really did try, i just don't wanna mess something up
[XPERIA X10 General] dk2000zx:
I second that =P
[XPERIA X10 General] tom0927:
Here's what I did to install JIT.. I didn't use the automated batch file installation posted here, got permission denied error, so I followed the original thread here: http://xdaforums.com/showthread.php?t=659756

I downloaded vlibs.zip and created the jit and dalbk folders on my sd card. Then opened command prompt to use adb.

adb pull /system/build.prop build.prop

build.prop was copied to my d:\tools folder (whatever folder your adb tools is in). Then I added dalvik.vm.execution-mode=int:jit at the end of the file, saved it, then copied and ran each line of code below one by one in the command prompt:

adb push build.prop /sdcard/jit/build.prop
adb shell
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock2 /system
cp /system/build.prop /sdcard/dalbk/
cp /system/bin/dalvikvm /sdcard/dalbk/
cp /system/lib/libdvm.so /sdcard/dalbk/
cp /system/lib/libnativehelper.so /sdcard/dalbk/
cd /sdcard/jit/bin
cp -f dalvikvm /system/bin/
busybox chmod 755 /system/bin/dalvikvm
cd /sdcard/jit
cp -f libdvm.so /system/lib/
cp -f libnativehelper.so /system/lib/
cat build.prop >/system/build.prop
chmod 644 /system/lib/libdvm.so
chmod 644 /system/lib/libnativehelper.so
chmod 666 /system/build.prop
sync
rm /data/dalvik-cache/*
reboot
[XPERIA X10 General] dk2000zx:
With command promp.. i get adb is not recognized as an internal.... blabla bla
[XPERIA X10 General] tom0927:
Do you have the android tools downloaded in your computer? If you don't, you can download the Tools.zip from jerpelea here: http://xdaforums.com/showpost.php?p=6514704&postcount=3

Then after you unzip it to c:\tools or whatever folder, you'll need to navigate to that folder first in command prompt before running the adb command.
[XPERIA X10 General] Astral07:
@dk2000zx

you have to open cmd, then navigate to where you installed adb in the tools folder (by default it's on C:), when you're there you have to write "adb shell"

@all

when i write adb shell, i get the $ sign, and from my understanding it should be #, how do i change that?

when i issue "adb pull /system/build.prop build.prop" command, i get adb: permission denied

EDIT: damn, looks like i was wrong, no adb shell command? it worked without that, at least "adb pull /system/build.prop build.prop" worked, i'll try to continue
[XPERIA X10 General] tom0927:
After typing adb shell, and you get $, type su (If it's the first time you've used the su command in adb, superuser on your phone might ask you if you allow or deny. Allow it if you want to continue :p) Then you'll get the # symbol.

Also, if you're in # (shell su mode) you don't need to type adb in front of each command.
[XPERIA X10 General] Astral07:
i'm having problems with the "su" command, when i type it from shell $, i get permission denied and nothing is prompted on my phone?? (and yes, i have root, titanium works like a charm as one example)
[XPERIA X10 General] dk2000zx:
ok sorry to be soo noob,... i now have the tools folder with the tools on my c drive... what do i trype on cmd to go to that tools folder so i can type adb shell?
[XPERIA X10 General] Astral07:
"cd.." to get you back one folder (so by default you need to type cd.. 2 times)

and then when you're at C:\ "cd tools"
[XPERIA X10 General] tom0927:
Was your phone screen on or off? The first time I ran su, my screen was off, and when I turned it on, superuser didn't pop up. I left the screen on and ran su again, and this time I got prompt to allow or deny.
[XPERIA X10 General] DangerPanda:
http://xdaforums.com/showthread.php?t=659756

I followed this link and finished it, at first phone wasn't laggy at all, but I found out i had SD mounted, so after I unmount SD, it got very laggy, so i guess it's building the cache now.

Just start from the THIS IS FOR JIT part.

You need to have the android sdk in your C:\ folder and busy box installed, and rooted... of course :)
[XPERIA X10 General] dk2000zx:
Omg thx imma try it out
[XPERIA X10 General] Astral07:
yes i just figured it out, it prompted me now, thanks

continuing...
[XPERIA X10 General] Astral07:
more problems...now that i'm in the # mode, when i copy paste "mount -o rw,remount -t yaffs2 /dev/block/mtdblock2 /system

" it just echoes it, nothing happens??
[XPERIA X10 General] tom0927:
yep, that's normal, it echo each command, but just continue on, it's working.
[XPERIA X10 General] dk2000zx:
i get adb not found...
[XPERIA X10 General] Astral07:
ok thanks, i did it and now it's booting for a loooong time

how to clear dalvik cache?
[XPERIA X10 General] DangerPanda:
660 with JIT enabled, normal usage no task kill etc.
[XPERIA X10 General] tom0927:
Did you use the code that I posted a few pages back? The last line few commands should be:

sync
rm /data/dalvik-cache/*
reboot

and the middle command is the one used to clear the dalvik cache
[XPERIA X10 General] dk2000zx:
ok did eveerything rebooting live

EDIT1: stuck on sony ericsson logo (bootscreen) not the white se logo at beginning

EDIT2: WORKS!!! gonna try quadrant
[XPERIA X10 General] Astral07:
download this

when you unzip, run SDK manager.exe, after that it will prompt you to update, do so

then you will have android-sdk_r07-windows folder on C:\

go in that folder and you will find a folder named tools

copy the folder tools to C:\ so that it's easier to get there with cmd

go into command prompt and write cd.. twice, than write cd tools, you should be in tools folder now and now just start with the code
[XPERIA X10 General] Astral07:
yeah, i followed your code, sorry i missed that part, didn't really read :)

it booted fine, and lagged a lot, i'm gonna try with the bench soon

finally! 648 first try...thanks tom, couldn't have done it without your help, cheers
[XPERIA X10 General] tom0927:
Good to hear :D It'll lag for a minute or two, then it's done.

edit 1 : I hate SE for caping the FPS at 32FPS....
[XPERIA X10 General] Astral07:
haha, let's not be greedy now :) they probably just shut down a bunch of processes & stuff

btw. anyone noticed any impact on the battery life?

and also, is there a good link that actually explains what JIT is? i just know it makes gaming better :) i wanna know how
[XPERIA X10 General] tom0927:
I wonder the same thing. Even when I killed all tasks and services/widgets, I still only get 650.. :(

And you're most welcome :D
[XPERIA X10 General] dk2000zx:
OH and thx alot for the help!! without u guys i would be stuck at 580

Does jit affect ur battwry life?
[XPERIA X10 General] wiedz:
Got 660 and 9.566.

And reboot loop (didnt clear dalvik cache), but shutdown and start the phone solve this. No more reboot.
[XPERIA X10 General] javagreen:
The battery life is just as good, if not better...atleast in my experience so far ;)

Also, anyone interested in what exactly JIT is, can read here
[XPERIA X10 General] kylec:
I tried following all the steps given by everyone but I still keep getting adb not found. Its my first time to use adb. Also can anyone recommend a tutorial thread for adb?
[XPERIA X10 General] HunteronX:
If you are using Windows then:

To install adb, download the sdk for Windows from here:

http://developer.android.com/sdk/index.html

And then extract the contents to the C: drive.

Now follow these instructions:

To add the "ADB" directory path as a system variable in windows...

Right-click on "My Computer" and select Properties. Next select the Advanced tab (Advanced Settings in Vista and Advanced System Settings in Windows 7) then select Environment Variables.

Click "New" under System Variables and add the following:

Variable: adb

Value: C:\android-sdk-windows\tools

When you connect your phone to the PC, the adb drivers should install automatically, if you've installed PC Companion already.

If not, get it from here:

http://www.sonyericsson.com/cws/support/softwaredownloads/detailed/pccompanion/xperiax10?cc=gb&lc=en
[XPERIA X10 General] Astral07:
don't forget NOT to mount SD card

thanks
[XPERIA X10 General] kylec:
thanks for replying... i followed your steps then moved on to the steps described in the JIT thread and when i typed adb remount... it said adb: permission denied

i already rooted aswell
[XPERIA X10 General] Astral07:
is your SD card mounted? you have to unmount it
[XPERIA X10 General] kylec:
yup my sd card is unmounted.

i also tried with the wifi adb and same thing. i just get keep getting "remount failed: operation not permitted"
[XPERIA X10 General] Astral07:
skip the remount and go to ADB pull /system/build.prop build.prop

also have your screen on x10 lit up so that it asks you for super user access
[XPERIA X10 General] tiggerbcn:
Please help, I'm trying to make the JIT with firmware 2.1 (Eclair), but I spend 2 things:

1 - The cp command does not exist, and I use busybox cp

2 - When I run this instruction:

#dalvikvm busybox cp-f /system/bin/

gives this error

cp: can not create '/system/bin/dalvikm': File exists

and the following instruction

#busybox chmod 755 /system/bin/ dalvikvm

gives this error

chmod: /system/bin/dalvikm: Operation not permitted

It's the same with the instructions:

busybox cp -f libdvm.so /system/lib/

busybox cp -f libnativehelper.so /system/lib/
[XPERIA X10 General] Cuspide:
you have to root shell, which is different from root your phone... i think

then adb will work
[XPERIA X10 General] Ballfuzz:
Ok, even though my phone works perfectly fine, I am still going to try this.

This makes the phone run a little quicker correct? Without draining your battery faster?

I know it's been said but I just want to make 100% sure before I try this and possibly ruin my phone lol.

*also, do any of you experience this lag I am reading about when opening applications?
[XPERIA X10 General] batemann:
does it work with x0 mini pro?
[XPERIA X10 General] Astral07:
so far i think my batt drain is the same as before, the phone does feel a bit quicker, though it just might be my imagination but it's definitely not slower :)

lag when opening apps? nope, no lag - the only lag is after you reboot the phone the first time you install JIT, then it has to rebuild some files for a minute or two and then it's ok
[XPERIA X10 General] kylec:
thanks everyone it worked! i did as suggested and skipped the adb remount. then i had to shell root at one point and then when i got to the part with cp... i had to use "busybox cp" instead.

all in all i noticed the app drawer is snappier, screen scrolling is smoother

just played with the camera... muuuuch faster! hell yeah. my gf's iphone can now no longer say her camera is faster haha
[XPERIA X10 General] Surge1:
I've literally tried every method in this thread for jit, gotten no errors but jit doesn't appear to be enabled (no task killers or lwp). any ideas?
[XPERIA X10 General] kylec:
i mostly followed the thread the zypherix posted but had to adjust for some errors... but once phone restarted i just ran the benchmark tests and got about hte same numbers as everyone else... also everything is faster... it doesnt show up in your taskkiller
[XPERIA X10 General] Surge1:
I know it doesn't I'm just not getting the same numbers as everyone else (still getting the high 400's or low 500's). I think the problem is that nothing is transfering to the dalbk folder? I look at it and it's empty

I use busybox in front of all my cp commands and it doesn't return errors, so unless im misunderstanding what the command does that folder shouldnt be empty?
[XPERIA X10 General] kylec:
lol now i get you. did you extract the files from the vmlibs.zip into your sdcard in the jit folder you created

edit: also did you clear the cache at the end?
[XPERIA X10 General] Surge1:
yea I tried clearing twice to make sure lol.

As for the jit folder it holds the following files, maybe im missing one?:

libdvm.so

libnativehelper.so

buid

bin which contains dalvikvm
[XPERIA X10 General] kylec:
hmm thats what i have aswell.. sorry i cant help anymore... hopefully someone with experience comes along lol
[XPERIA X10 General] Surge1:
heres hopin =P......I'll keep fidgeting in the meantime
[XPERIA X10 General] tom0927:
Can you copy & paste what you typed and what command prompt returned in the command prompt window? Maybe we can see if there were any errors.
[XPERIA X10 General] Surge1:
After some further digging it would appear that my cp commands (if any commands at all) are not moving my files to where they need to be......any recommendations?
[XPERIA X10 General] Surge1:
Most recently I literally copied each command you previously posted (so I'm lucky your helping =] ) with an addition of busybox in front of all the cp statements and all that was returned were echos of the commands

edit: when I say copied I mean I highlighted them and then right click pasted them individually, just to ensure I didn't have typo's
[XPERIA X10 General] tom0927:
Why are you putting busybox in front of each command? If you're in the shell as su, then you shouldn't need to use the busybox command.

And the echo seems normal, I got the same, and so did Astral07.
[XPERIA X10 General] Surge1:
when I don't include the busybox command I get the command echoed back, follwed by "cp not found"....prior research suggested it was sometimes necessary

edit: busybox was installed by titanium backup and appears to be ok
[XPERIA X10 General] Surge1:
went back and messed with busybox some more / upgraded and fixed the need for busybox to be present in front of commands .....

happily reporting

Is it posible to install JIT in the mini / mini pro?
[XPERIA X10 General] javagreen:
Which is the process that re/builds the cache? Is it "android.process.acore"?

Just asking becasue I uninstalled Rock Player 'cause it was running like ass and then re-installed it. The phone got laggy -- so I suspect it's the JIT at work here. Checked cpu load with the "Android System Info" tool and it shows 100% CPU usage for com.android.acore.

It also shows :

package : com.fede.launcher

That's Launcher Pro -- any idea why it's showing it's 100% cpu usage for the launcherpro process alongwith com.android.acore? Anyone else encountered this?
[XPERIA X10 General] akila87:
Damn mine is better without JIT :(

I get 643 without JIT and 614 with JIT felt very slow when using JIT :mad::mad::mad: :confused:
[XPERIA X10 General] javagreen:
An observation I just made : using home switcher when I switched back to the stock home, the lag stopped instantly and cpu usage went back to 10-11%. I have now reset LauncherPro back as the default launcher and am rebooting, let's see...

EDIT: No luck, back to 100% cpu usage after reboot. Gonna try re-installing LP.
