I will update the files every time I find a problem
WARNING PLEASE READ:
Project JIT is highly highly experimental! If you are to do this, MAKE A NANDROID BACKUP IN ROM MANAGER OR RECOVERY! There are always chances of something going wrong. I nor anyone else is responsible of what happens.
Experienced users please know the possible risks:
Boot Looping, requiring a restore
Constant FC's
Wiping everything
These are just the risks, please note it is not 100%
JIT stands for Just in time compiler. It does not like Touchwiz, so download ADW.Launcher or LauncherPro before starting and set it as default.
This whole process is in ADB. If you dont know how, or what it is, DONT DO IT!
Things to do before you start:
-Download a different launcher than TouchWiz
-Make a backup in recovery or Rom Manager
-Did I mention DO A BACKUP!
-If you have an external SD card, pull it out
-Download the vmlibs file
What I expect you to know before you start:
-ADB
-What JIT is
-How this will effect the performance
-The risks
-How its not my fault if you screw your phone over
-How experimental this is
-How to make a nandroid backup
-How to make a nandroid restore
Remember, this is experimental and I cannot guarantee for it to completely work.
Download This- vmlibs.zip
Then follow these steps:
-Make a backup!!!
-Create 2 folders on your internal sdcard: “jit” & “dalbk”
-Extract the vmlibs.zip to the “jit” folder on your sdcard
-Using ADB pull your build.prop
Code:
adb remount
ADB pull /system/build.prop build.prop
-It will place the file in your c:/android/tools folder
-Edit this using notepad, text edit or similiar program.
-Add the following line to the end of the build.prop: dalvik.vm.execution-mode=int:jit
-Edit the following line:dalvik.vm.startheapsize=8m
to: dalvik.vm.startheapsize=12m
-Save the changes
-Push it back to your “jit” folder on the sdcard
Code:
ADB push build.prop /sdcard/jit/build.prop
This will back up your current files. So you can disable jit, but if your phone boot loops, thats why you have A BACKUP!
Code:
ADB shell
su
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/
This will enable jit on your phone.
Code:
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
reboot recovery
While in recovery, wipe the dalvik cache, this will prevent it from boot looping.
To Disable
Code:
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /sdcard/dalbk/
cat build.prop >/system/build.prop
cp -f dalvikvm /system/bin
busybox chmod 755 /system/bin/dalvikvm
cp -f libdvm.so /system/lib/
cp -f libnativehelper.so /system/lib/
chmod 644 /system/lib/libdvm.so
chmod 644 /system/lib/libnativehelper.so
chmod 666 /system/build.prop
sync
reboot
If that fails, that is why you have a backup. To restore, go to recovery, click on nandroid, and restore from your backup.

It didn't here. Not sure if that is due to other fsckup or the fact that I was running I9k rom with my kernel and sdcard hack...
Restoring to stock to give this a whirl
tommarow I will update the vmlibs file and see if it works better.
Oh, and tell me what your problems are

Doesn't boot past the white at&t screen. Again, I was running I9k rom with custom kernel and ext hack, not exactly the cleanest test bed. Flashing stock to test now (can't get into recovery on this thing anyway it seems).

Hold on. Before you do that, let me up the file.

It should work better. I used it just now, and it works for me

Same story with the stock rom and old file, just FYI. Flashing back and trying the new one.

Yeah, thats why I had to fix some stuff lol. I noticed that it wouldnt go past the att screen. Now it should work correctly. The worst that could happen now is it boot loops on the Galaxy S screen
Haha I was just about to post the same problem, downloading new file and trying it again!

Hey, when you edit the build.prop to add the dalvik vm line, can you look for the vm heap size and change it from 48 to 32? I am about to test doing that, and I would like more feedback
Doh, didn't read this until after applying it all... it's in the process of booting though- it got past the AT&T logo so that's progress!

ATM I'm now stuck sitting at the GalaxyS logo, I'm going to give it a little more time, but I suspect it might be stuck.

Do you know how to run a logcat?
Its gonna take a while because its re writing the dalvik cache
That I do not, but I'm willing to try it if you can give me a quick crash course

Well I am looking at my logcat now, and it is just repeating boot animation.
A logcat is useful, so how you do it is adb logcat.
I changed a couple things to test around with here is what I did-
I added all of this to the build.prop-
#JIT
dalvik.vm.execution-mode=int:jit
and changed:
dalvik.vm.heapsize=48m
to
dalvik.vm.heapsize=32m
Right now I am resorting to try the older vmlibs with the new settings
Ran logcat, it's also trapped at looping animation, and I didn't touch the heapsize
W/BootAnimationSEC< 2194: ms4631 - Repeat Loop Animation
Over and over and over, is there something else in the buffer you'd like me to look for?

No thanks for the feedback. Its only worked for me once, and then when I rebooted it got stuck in a boot loop.
Whats a device thats running android 2.1, and has a jit hack that is extremely similar to the Galaxy S series?
Hi guys
I'd manage to manually deodex the app and framework file from my stock rom. The problem are I can't push them either thru adb nor update.zip. Been googling around but can't really get a correct adb command for sgs. I need to push these files so that I can install themes. Anybody who can guide please help. Thanks in advance.
You need super user permission to push things into read only memory. So you would need to go through adb shell, mount whatever folder framework is in to readable, etc.

Hi snapper.fishes
By the way, I got superuser permission. The only problem I don't know the correct command for the adb shell - su - mount etc, etc....
This are the command I got from Droid forum but it does not work for SGS I guest.
adb shell
su
stop
mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
cp /sdcard/done_app/* /system/app/
cp /sdcard/done_frame/* /system/framework/
rm /system/app/*.odex
rm /system/framework/*.odex
mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
reboot
Anybody got any idea?
Try this:
adb shell
su
mount -o rw,remount /system
cp /sdcard/done_app/* /system/app/
cp /sdcard/done_frame/* /system/framework/
rm /system/app/*.odex
rm /system/framework/*.odex
mount -o ro,remount /system
reboot

Thanks for the tips g00ndu. If I push those deodex file, they will overide and delete all the odex file right? Should I disable the universal lagfix first and is it safe pushing deodex file this way?

I say remove the lagfix first. It's not necessary, but if you do screw up your phone you are going to have to reflash your phone, and the last thing you want to do is to flash your phone with lagfix on.

It's been a long time since I pushed files this way. Right now I'm using update zips and flash it via ulfk. Reason: it is much more simpler and more effective. If I remember correctly, your apk files need to be deleted too before you can push your deodexed apks and jars files to the system folder if you do it via adb.
Besides, I would not advocate this method of pushing through adb, bcos, there is always chances that your /system, /data partitions may result in data corruption.
Try using update zip.

Thanks for your reply g00ndu. I've already try that. But after the zip file updated nothing happen. Maybe the zip creator that I use is not compatible with sgs. Can you kindly link to the correct source for sgs. Or maybe you can post the file and tutorial here so that we can learn the correct method from you. Thank you so much for that.
Anybody can help?

Hey angiogram... I'm not sure if this thread still has a pulse, but I came across this thread and feel confident I can offer you some great information.
g00udu was on the right track, only one small detail I would add is reverting the permissions back to the system files once returned to the system directory.
See this link http://forum.xda-developers.com/showthread.php?t=990238
for an extremely detailed step by step how to perform this process from beginning to end.
If this issue has been resolved, keep it for future reference or pass it on to someone who you believe it may help.
Peace-
Thanks Liv33vil.

Hope this is the right place to post this.
My Atrix is rooted stock 1.83 .
I'm trying to "adb push" some OGG files to "/system/media/audio/" to add-to and replace some of the existing system sounds, especially that bloody annoying keypress (typewriter) sound, but I'm getting the following error (which makes sense):
Read-only file system
Tried using Root Explorer, same issue...again makes sense since its mounted as Read only on boot.
I tried booting into recovery mode, but I can't access the phone via ADB at all, even with USB Debug enabled. I also tried "adb remount" command, no luck either. I get an error "operation not permitted".
So, does anyone know the correct sequence of commands I need in ADB to remount the Atrix /system folder as RW??
What I have been doing is using adb push to the /sdcard then using adb shell then su then
mount -t rfs -o remount,rw /dev/stl5 /system
Then cp /sdcard/whatever /system/media
Sent from my MB860 using XDA App
EDIT: im at my computer now so I can write this easier to understand, lol
Lets say the file you want to change is called whatever.ogg
Code:
adb push whatever.ogg /sdcard/whatever.ogg
adb shell
su
mount -t rfs -o remount,rw /dev/stl5 /system
cp /sdcard/whatever.ogg /system/media/audio/notifications
when you access root explorer, does it let you know that it has been granted supervisor privilages? Does it give you the option to change from read to write? what did you use to root? I had to run the original Aroot three times before if finally gave me root.
You're the best, worked perfectly Can't believe that hideous typewriter sound is gone, it only took me 1.5 years as an Android user to finaly say enough is enough. Whomever thought it was a good idea to mimic the sound of an 1800's typewriter on a 21st century device needs to be fired.
Thanks again.

Well congrats! that was the dumbest thing ever. NEVER attempt something like that unless you have CWM or equivalent installed, have a backup, and know what you are doing.
Have you tried to read your device's xda forum?
Please Help
Hahaha, can you help me?
i want to change my /system/framework folder by using the POWER and UP volume keys
i had a backup of my system/framework in my SD..
What should i do?
Hello All.
Here are the framework-res.apk and build.prop files for the Optimus One, Stock 2.3.3 firmware. All you need to do is replace those files and you will get the CRT ScreenOff effect
I used the post by Skynet28, modified a little to only use adb commands.
This was the first thing done after rooting the phone.
-NEEDED:
Rooted phone
.7Z file View attachment 949259
5 Minutes of your time
NOTE: YOU WILL MOST PROBABLY LOOSE YOUR PHONEBOOK, I DID WHILE DOING ALL THIS. PLEASE BACK THAT UP.
The procedure to install is as follows:
You must set the /system on the phone with RW permision
From a Command Prompt:
First we locate where /system is mounted
Code:
adb shell
su
cat /proc/mounts
Locate /system in the mount and write down the mountpoint (mtdblock1 or similar)
the type
Code:
mount -o rw,remount /dev/block/[I][COLOR="Purple"]MOUNTPOINT[/COLOR][/I] /system
exit
exit
Then we push both files to the phone with the folowing adb command
Code:
adb push framework-res.apk /system/framework
adb push build.prop /system
Finally we chmod those 2 files
Code:
adb shell
su
cd /system/framework
chmod 664 framework-res.apk
cd /system
chmod 664 build.prop
exit
exit

What is better way to unroot you S4 on MF3 Odin back to stock MF3 or by SU full unroot?
It'll somewhat depend on why you want to remove root. But I've always used odin. You will lose all your apps this easy though. I've never tried using unroot inside super su and don't know if it leaves somethings behind.
Personally, I like to make sure everything is completely gone by doing the following:
First remove Safestrap via ADB:
Code:
su
mount -o remount,rw /system
mv /system/etc/init.qcom.modem_links.sh.bin /system/etc/init.qcom.modem_links.sh
rm -rf /system/etc/safestrap
rm /system/etc/firmware/q6.mdt
ln -s /firmware/image/q6.mdt /system/etc/firmware/q6.mdt
mount -o remount,ro /system
Then, remove SU & Busybox via Root Explorer:
1. Navigate to /system/xbin
2. Delete busybox and SU
3. Naviate to /system/bin
4. Delete SU
5. Uninstall Superuser from the Applications Menu
Finally, nuke the entire thing by ODINing back to MF3 stock with this:

You really only need to do the last step, but I always like to be extra safe.

Friend of mine don't have SafeStrip on his phone. BTW you can remove last version of SS with appication manager.
2nd step will remove will remove root and leave the rest of the OS intact. I think SU full unroot leaves busybox behind, and you cant delete it without root.
