I had been messing about with a script to pull apks off my phone, zipalign them and then push them back, but then I saw wesgarner's CM build with a binary and script for use on your phone. I don't really want to mess round with flashing a ROM just for that though, so I've ripped them out and uploaded them below. Another reason is I want to run this manually (with GScript) rather than on boot (as it does in wesgarner's ROM).
I take no credit for this, the binary and script were both taken from wesgarner's CM buiild.
To "install" this, just adb push the two files in the zip below onto your phone with:
Code:
adb shell mount -o remount,rw /system
adb push zipalign /system/bin
adb push zipalign_apks /system/sd/zipalign_apks.sh
adb shell chmod 755 /system/bin/zipalign /system/sd/zipalign_apks.sh
adb shell mount -o remount,ro /system
Then anytime you want to run the script just do:
Code:
adb shell sh /system/sd/zipalign_apks.sh
Or in terminal:
Code:
su
sh /system/sd/zipalign_apks.sh
Has been tested on CM 4.2.7.1

i do not even know what zipalign does .. but i did add this to my script
# lucid -z
so .. what does it do exactly?

Sweet... Thanks...
I was surprised that more than half of the Apps I have were already ZipAligned...

APKs (as you probably already know) are just zip files. zipalign simply aligns the APK on 4-byte boundaries which Android is more efficient wrt memory access.

Since the 1.6 SDK was released, the ADT does this automatically on APK export. Therefore any app which has been updated since ~September (and was developed using the ADT Eclipse plugin) will be zipalign'd. I was more surprised that 12 out of the 43 apps on my phone weren't aligned!

that's awesome .. thanks for the link .. i hadn't read about that

Thanks much for this!
Here is a simple gscript to install zipalign after a wipe or new build flash.
You must first create directory /sdcard/zipalign and place zipalign from the zip in the OP there. Path to the file should now be /sdcard/zipalign/zipalign.
Place this script in your gscript folder (after removing .txt from the name) and load it in gscript with su permissions.
I also find it easier to run the script in the zip from the OP in Gscript as well. Instead of placing it in /system/sd run this (assumes zipalign_apks.sh is at root of C:\)
Code:
adb remount
adb push C:\zipalign_apks.sh /sdcard/gscript/zipalign_apks.sh
Then just load it into Gsrcipt with su permissions as with the other script.
Easiest of all may just be to use the commands within Lucid's script. But, I'm comfortable with Gscript, and I can make it 2 clicks away.
EDIT: First execution, you may want to run the original way, because guess what? Gscript isn't zipaligned. But it worked fine just the same.

worked great thanks.

Thanks. I didn't want to flash whole ROM to zipalign apps, so script was very handy.
Actually I've zipaligned only 2 apps, one of them was everybody loved Linda

so anyone wanna bless me with a terminal code to install the script?

I put a quick explanation of my script on my ROM page: here ya go (rough explanation)
Zip Align reduces the amount of RAM used during processing running for a major speed increase in dex-opt and running the apps, along with the RAM hack and a CC (or your userinit) boots speeds incredibly and better usability of apps (boot and system) in Android: http://developer.android.com/guide/d.../zipalign.html
Most developers have not used this yet (CM does ZipAlign his apps), but this does for the system apps provided from the now old Google Apps

Agreed. The Market won't let non-zipaligned apps be uploaded.

it will really, it doesn't detect the diff
Also, SDK4 didn't really include an enforced ZipAlign like SDK5 (eclair) does
Plus I built the ZipAlign from source from eclair - so this script may not update them all perfectly

Unzip the files to your SD Card, then:
Code:
su
mount -o remount,rw /system
mv /sdcard/zipalign /system/bin
mv /sdcard/zipalign_apks /system/sd/zipalign_apks.sh
chmod 755 /system/bin/zipalign /system/sd/zipalign_apks.sh
mount -o remount,ro /system

Post deleted becoz it was redundant

can someone make a script for windows or a bat file that can zipalign a batch of apks? I am not that ofay with line commands and when i create a new theme (which i often do), i then have to go and zipalign every single apk i have altered 1 at a time..... i do:
Code:
zipalign -f -v 4 E:\app\theapp.apk E:\app\theapp.apk.out

This isnt working for me bc of the .sh after zipalign_apks .. do i rename the zipalign_apks to zipalign_apks.sh after unzipping?
edit:that worked THANKS!

[HACK] (!update 04/26/2010) JIT enabled Dalvik VM on Android 1.6 (Dusted Donuts)

Update (fix for /cache/dalvik-cache 04-26-2010): Really only use this if your having issues using the symbolic link fixes posted by other members or are just out of free space on /cache. First the new issues people are experiencing is in cm-based-kernels from 4.2.15.x and not JIT enabled DalvikVM and people using danger/death spl will experience problems faster. Lack of space on /cache is a problem and will cause market downloads to fail as well as email attachments. The other problem is the kernel fails for various and unknown reasons to mount bind /cache/dalvik-cache to /data/dalvik-cache.
The other issue is the use to dalvik-cache clearing scripts and options in RA recovery, stop clearing your dalvik-cache, the .dex files are created when missing and you do not get any benefits by doing so and cause more wearing leveling of NAND, plus the script in RA recovery doesn't appear to look at /cache/dalvik-cache for dex files. This little update script (when installed correctly).
Understand that /cache/dalvik-cache is a newer option as a means to free up space on /data is by using /cache/dalvik-cache as a first storage of dex files then using the standard /data/dalvik-cache for over flow of dex files and newer installed apps. Somewhere along the way something may throw this and you get douplicate dex files in both locations, one way to check is to boot into recovery and
Code:
mount -a
and check dalvik-cache directories in both /cache and /data for douplicate dex files.
The script will fix these issues, or should at least:
Endless loop FCs on boot
broken /cache/dalvik-cache mount
no binded mount
missing user apps
missing system apps
failed market downloads
non-working symlink patches and installers (no need to run these, they will break this patch)
fixes duplicate dex files in both /cache/dalvik-cache and <target>/dalvik-cache (because it deletes /cache/dalvik-cache)
Will not Fix:
your ignorance
your unwillingness to read
your unwillingness to learn
your compulsive ROM flashing disorder
your compulsive dalvik-cache clearing syndrome
version 1.1.1(updated 4/27/2010 @ 10:10 PM) is current and was slapped together from Phonekenstein, it doesn't look for the existance of /cache/dalvik-cache it assumes it's there and deletes it wether it's a directory, a symlink or a file, re-creates a new empty /cache/dalvik-cache with Android default permissions and mount binds it to /data/dalvik-cache (be it a directory, a symlink or another binded mount) /cache/dalvik-cache will follow the target /data/dalvik-cache (no worries for apps2sd users or non-apps2sd users).
Script will turn on the blue LED when booting so you know it executed (if it annoys you then edit the script and make it pink)
Tested on Cyanogen MOD 4.2.15.1 and SuperD 1.10.3:
with and without apps2sd
with and without a /dev/block/mmcblk0p2 (apps2sd script nulled)
with and without a custom /dev/block/mmcblk0p4
with mount binded /ext/dalvik-cache (mmcblk0p4) to /data/dalvik-cache
with /data/dalvik-cache as a symbolic link to /ext/dalvik-cache (mmcblk0p4)
All scenarios experienced no failures as long as you set your permissions correctly on all targets and files and /cache/dalvik-cache followed and binded flawlessly.
install is simple and can be done through terminal:
1. download 86dalvik-cache-fix <--Long press and chose "save link as" (also attached to this post)
2. open terminal and issue these commands:
NOTE: COMMANDS ARE CASE sensitive in LINUX and as such ANDROID!!!!!!
ALL OFF THESE COMMANDS ARE IN lower case. SO Turn off your Auto-Caps options in your keyboard options. These command assume you downloaded the script using your the web browser on your G1/Magic whatever phone and the file is located in /sdcard/download (the default location for web browser downloads).
Code:
su
mount -o rw,remount /system
cp /sdcard/download/86dalvik-cache-fix.txt /system/etc/init.d/86dalvik-cache-fix
chown 0:2000 /system/etc/init.d/86dalvik-cache-fix
chmod 755 /system/etc/init.d/86dalvik-cache-fix
sync
reboot
Why 86dalvik-cache-fix? We want the script to execute after all scripts in /system/etc/init.d/ including /system/sd/userinit.sh (if you are using one) and before script 99. 86 because in 1987 everything got 86'd.
If you are having a problem getting the script to execute, copy it or merge it into /system/sd/userinit.sh (even if you aren't using a mmcblk0p2(ext partition)) it may make it work with FastTest builds, however the permissions on his builds appear to be root everything and I have problems getting the script to execute out of /system/etc/init.d even with root permissions.
--------------------------------------------------------------------------------------------------------------
Primer: Read this about Dalvik VM http://en.wikipedia.org/wiki/Dalvik_virtual_machine
Read this to: Google Groups post about JIT compiler for Dalvik VM from Android-Platform Link
From the post we see that this particular compiled library is ALPHA, so results can vary, but from reading most posts in this thread the results are right near the talked about 3x faster code, stability is going to vary on what apps and or widgets are running. More Widgets = slower performance as these have processes that are eating cycles. When testing with Linpack wait for the advertisement to load first then tap the benchmark button and remove your finger from the touch screen. Background process such that interrupt or having auto-rotate enabled while testing is going to give you slower benchmarks.
In short your apps should load faster and run faster, particularly 3D games. The web browser is faster and you can actually scroll through pages even while graphics are still loading.
The reboot when enabling it is long even appearing to hang at the G1 Screen for 5 minutes or more but once it starts booting past this you will know that your ROM is compatible. The cause is that the dex files are being optimized, after about a third reboot, your ROM should feel pretty snappy and launching apps should be quicker as well as switching apps. The snappiness lasts as well and as some may have said that it's a placebo effect are wrong. Bench mark readings prove it and more importantly a few ROM builders have included this in their 2.1 ROMs as experimental.
The libdvm.so that t3steve cross compiled for the DROID at the time was for Android 2.0, the library works for with newer ROMs Android 1.6 that have some eclair pieces built into the kernel, CyanogenMOD has been using bits and pieces for a while now, if other ROM builders have been using his kernel and framework than a good chance it will work for your phone as well.
I have nothing to do with the compiling of this or the exact functions of enabling JIT except that I had a hunch that the combo might work and it did, so I'm sharing it.
If you aren't good at typing in commands, or don't know how to extract a zip file and understand that a sub folder may or may not exist where you have extracted said zip file to, well.... you may run into some issues, maybe a video tutorial for basic command line on youtube would be a good place to learn.
I wanted to make a very detailed post on www.andoidonroids.com about how to mash the JIT enabled Dalvik VM library into Android 1.6 Donuts I'm calling the hack "Dusted Donuts" and take from the name for what you will. I have been using the JIT enabled Dalvik VM for about two weeks and i runs decent but not perfect. Anyhow a death in the family Sunday has kept me from making a decent post and haven't had the time to get to the website and post and cross post and give credit where due.
No doubt that aaraya1516 broke the news on http://forum.xda-developers.com/showpost.php?p=5703076&postcount=193 as he was first to break the hack on FastTest, not taking anything away from him on that.
My testing goes back two weeks or more even during the 580mhz & 780mhz hack, I was waiting for someone to compile a boot.img with some 2.x stuff and sure enough the carlospants boot.img from ctso worked with enabling JIT for Dalvik VM, but as we know now the overclocking doesn't work at the moment.
Thank Cyanogen and t3hSteve of which may not know that this was entirely possible. Cyanogen mixed in enough Eclair into his Donuts (he's like Willy Wonka) that makes it possible to use the cross compiled JIT enabled Dalvik VM library from 2.1 for the Motorola DROID 2.0.1 libdvm.so that t3hSteve of www.alldroid.com compiled for the custom roms on Droid.
WARNING: Using other methods supplied from other forum members that include replacing the build.prop may cause problems, using the build.prop from the original VMLIBS.ZIP (which is here for reference and original source for libdvm.so) is definitely going to cause ROM and application problems. Hello....use your head here... the VMLIBS.ZIP is for Motorola DROIDS, why would you put the build.prop file for a DROID on your G1 and expect your apps or ROM to work afterwards? It's so simple, you need 1 file, it's called libdvm.so it goes in /system/lib a file by the same name already exists there and it's in your best interest to at least back it up before overwriting it and gives you the ability in the event that your system doesn't boot up you can restore it through recovery console and get your phone to boot past the G1 screen.
FYI: Some ROMs have the option dalvik.vm.execution-mode=int:fast in the /system/build.prop file, this would need to be changed to dalvik.vm.execution-mode=int:jit or commented out or deleted. If you want to play with advanced options create /data/local.prop and fiddle in there with options available from typing dalvikvm -h in your console or terminal app.
Required:
1. Android 1.6 ROMS with a bit Eclair stuff in the Kernel and framework such as Cyanogen ROM 4.2.x, Super D 1.8 - 1.92, WG Y2.6, FastTest, KingKlick Eclair and more.. This libdvm.so works on Android 2.1 as well as it seems it should.. 1 st bootup is slow and I recommend you let it sit even when desktops are up for a couple of minutes and then reboot it, 2nd and 3rd bootups are faster and smoother response overall even for long durations, days.
FIX YOUR FILE SYSTEM FIRST !!!!!! Got to do it from Recovery Console, It's partly the cause of poorly running ROMS and takes seriously longer to type the command than to fix your unknowingly faulty file system. EXT2 is the worst offender and the built in function to repair falls short, even more so when checking EXT4.
Code:
#e2fsck -fcpDC0 /dev/block/mmcblk0p2
#reboot recovery
For the lazy fingers
#e2fsck -fcpDC0 /*/*/*0p2
#reboot recovery
1. Download www.androidonroids.com/dusted-donuts (File has 3 scripts backup, install, restore, 2 folders, 1 libdvm.so)
2. Extract zip to root of /sdcard or where ever you like (the zip has a folder containing the files named dusted-donuts)
3. Open Terminal or go to Recovery Console
FYI when running the install through Terminal your system may freeze or reboot and if it does I highly recommend that you prepare to enter Recovery Mode and check your file system. EXT2 corrupts quickly choosing this for apps2sd to use is not the best option especially if you are using custom ROMs that may lockup or reboot, basically that's a crash.
Code:
$su
#mount -o rw,remount auto /sdcard
#cd /sdcard/dusted-donuts
#sh backup
#sh install
#sync
#reboot
Check the Dalvik VM execution mode. look at the bottom line with_jit means the it is installed , and look at all of those options that can be jammed into your build.prop and local.prop files
Code:
$su
#dalvikvm -h
Phone won't boot past G1 screen? Go to recovery console and restore libdvm.so (give it at least 5 minutes first before giving up)
Code:
#mount -o rw,remount auto /sdcard
#cd /sdcard/dusted-donuts
#sh restore
#sync
#reboot
---------------------------------------------------------------------------------------------------------------------
prefer to use VMLIBS.ZIP from t3hSteve? This is how you can install using that.
Required:
1. Android 1.6 ROMS with a bit Eclair stuff in the Kernel and framework such as Cyanogen ROM 4.2.x, Super D 1.8 - 19.2, WG Y2.6, FastTest, KingKlick Eclair and more.. This libdvm.so works on Android 2.1 as well as it seems it should..
How to install: (easier to go in recovery mode but can be done through terminal)
1. Download the VMLIBS.ZIP from t3hSteve of allroid.com http://alldroid.org/download/file.php?id=1374
2. You only need the libdvm.so file of which appears to be JIT enabled by default.
3. Backup the original libdvm.so #cp /system/lib/libdvm.so /sdcard/libdvm.so
4. Copy the JIT enabled libdvm.so #cp -f /sdcard/vmlibs/libdvm.so /system/lib/libdvm.so
5. Set permissions on the file #chmod 644 /system/lib/libdvm.so
Optional for disabling: (easier to do vi through recovery console, since the back key escapes out of terminal)
To disable JIT MODE but want to keep the libdvm.so create a local.prop in /data and add dalvik.vm.execution-mode=int:fast
#vi /data/local.prop
press the i key to enter vi interactive mode
type dalvik.vm.execution-mode=int:fast
press back key to exit vi interactive mode
to write the file out and quit vi type :wq
or
restore your backed libdvm.so file from the sdcard.

Enjoi! the dusted donuts,
-Licknuts (me? I'm like Varuca Salt, I want another pony)
Vendor G1 roms around 1.2 Mflops, Custom G1 roms are around 2.4 MFlops/s and with JIT compiled Dalvik VM 3.6 MFlops/s. At most you will see 3.5 MFlops/s fairly consistently with a minimal load on your system and highs at 3.7 Mflops/s. Test before and after using Linpack from the Market, it's free.
The 13.236 Mflops/s is not normal and you will probably not see with your testing, I have seen 5.x & 7.x but these are far and few between and this took a while with tweaked configurations/settings with a persistent app to kill processes, it is attainable and I hope a ROM developer finds the sweet spot to exploit.

Looks nice.
Pre-JIT enabled: 2.194 Mflops/s
Post-enabled: 3.459 Mflops/s
Not quite getting the results you have there.
Running SuperD 1.9.2 Black W/ Nexus Theme. I copied it twice to make sure that the libdvm.so was copied correctly to the directory. Rebooted the phone, same results. Looks very promising though. If I did something wrong, lemme know.
Managed to get #10 on G1 Benchmarks with 3.583 Mflops/s... still nowhere near 13.~ Mflops/s

same here. Running Super D 1.9 on my magic
before JIT I got 1.xxxx Mflops/s
after i have 2.xxxx Mflops/s
how do you get the 13 Mflops/s ?
-edit-
with swap disabled i'm getting 3.5 Mflops/s

Speed your *hit up!

it works with and without swap.
Just the benchmark result is better when swap is turned off.
Got nearly the same as samsara00:
Rom: SuperD 1.9.2
Before (swap off): ~ 2.3 MFlops/s
After JIT enabling (swap off): ~ 3.5 MFlops/s
But the increase to 13.x seems so unreal, why is there only one result that high in the toplist of greene.com!?

Now to find out if this actually speeds up everyday use lol
CM4.2.14.1
Before: 2.3
After: 3.5
Wow! This made my 3G connection faster too. Was only getting 1500kbps before, now getting on average 3200kbps. Awesome. I'm located in Toronto, on Rogers.
Question: Is this Google's JIT? Will Myraids Dalvik Turbo be faster?

Doesn't boot past the G1 screen when using Dwangs 1.17.1 Assume thats because it has no Eclair in it, but it was worth the dream .

Waw!! great works!!
left is before - right one is after
on CM 4.2.14.1, enabled Swap 64MB, CC ON, RAM Hacked

So do we copy the zip to the root of our sd card? Do I extract it first and just copy the one file? The instructions are kind of vague.

Not to be rude, but if you don't understand those directions, this isn't the sort of thing you should try to do yourself. Wait for a ROM builder to add this in. The directions are perfectly clear, you just need to understand command line use.
If you want to learn something about CLI use, install Linux on your computer and learn to use it without the GUI. If you don't want to do that, google for "cygwin" and use the bash shell they provide for Windows based machines.

Personally, I used adb and just pushed the darn file lol works perfectly fine, like everything else I've ever pushed. Just don't forget to set the permissions for the file.

tried in a terminal and with adb getting read-only file system when trying to copy over the libdvm.so file

Nothing wrong with adb. Hell, I used SSH to do it. Just about anything will work, you just have to know what you're doing.
Damn.... I just rebooted and it took about half the time it used to.
Tried the Linpack benchmark, getting about 3.5 with SuperD 1.9.2 w/Compcache 16M swappiness=10. Fresh reboot, obviously. Lock your CPU to 528 (min and max) for more consistent results. When I have 128min 528max, it gives different results depending on the current CPU speed. SetCPU or Overclock Widget helps a lot here. No instability noticed yet, but this should probably be considered an unstable hack for now till we all get more experience with it. I know OpenEclair removed the JIT VM because of stability problems.

download files here and copy them on the sdcard
created a folder /sdcard/jit and put the three files in it
make a folder /sdcard/dalbk and copy the original files
adb pull /system/build.prop .
Open in WordPad/Textpad and add as the last line: dalvik.vm.execution-mode=int:jit
SAVE IT, copy/push it on the /sdcard/jit folder

I'm about to try this myself.. has anyone noticed an overall increase in speed? Benchmarks are great but it's all about how it actually performs!
I'll post my own findings in a bit.

Dalvik JIT working on Desire with Sense UI!

NEW VERSION! Less hackish!
Commenting out some code that limits how much heap-memory an application can allocate + adding one dummy JNI function , JIT-enabled Dalvik is now working very stable (i haven't had one crash so far for some hours).
EDIT: this version is not just a hack based on commenting out some code. The only code that needed hacking was dalvik/vm/native/dalvik_system_VMRuntime.c and dalvik/vm/alloc/HeapSource.c . The other fix is just a change you need to make in /system/build.prop - This is important
Instructions:
0. BACKUP ALL THE FILES THAT YOU ARE OVERWRITING HERE !!!
1. Copy libdvm.so and libnativehelper.so to /system/lib/
2. Copy dalvikvm to /system/bin
3. chmod 0755 /system/bin/dalvikvm
4. chmod 0644 /system/lib/libnativehelper.so /system/lib/libdvm.so
5. Optionally clear dalvik-cache (?) I didn't have to though
6. Append the line "dalvik.vm.execution-mode=int:jit" to /system/build.prop
7. Change line in /system/build.prop: dalvik.vm.heapsize=24m to dalvik.vm.heapsize=38m (38 megs should be more than sufficient so far. The problem is, as someone also pointed out in this thread, that JIT increases the memory usage
Remember you have to mount the /system partition in recovery mode.

Thaaank you

Wouldn't mind giving this a spin, but how does one remove it if it doesn't work out? Assume you can just remove the files and the line in build.prop?

I figured that out and went ahead anyway Getting 9.3-ish on Linpack. How're you getting 10+?

Is it compatible with the cm506 for desire?

Ah yeah, just figured that out. All should in theory be working now.

awesome, thanks gr0gmint

[HOW TO?] Install and run 2nd-init for defy

Original post HERE from r2beta0
DANGER!!! Its NOT for Defy! Needs to mobify the 2nd-init first
Hopping some devs to fix it for Defy!
r2beta0 said:
Credit for koush for Droid2 Bootstrap
Credit for edgardcastro for sharing lots of information about 2nd-boot on Milestone1
Credit for Skrilax_CZ for 2nd-init and sh hijack
WARNING: Use this ONLY if you know exactly what you are doing. This guide will make major changes in the /system partition and may turn the phone inoperative. I won’t hold responsibility if you brick your phone or to any damages it may cause.
Pre-requisites: A computer with Android SDK and ADB drivers installed and working. It’s recommended to have RSD Lite 4.9 and the appropriate SBF image just in case anything goes wrong.
This guide was made using a Brazilian Motorola Milestone2 based on Brazil Retail SBF and a computer running Windows Vista 32-bits. I started it from the scratch by flashing my phone with RSD Lite 4.9 and performing a full data/cache wipe, just to make sure any changes were discarded.
Note: Commands that should be entered in command prompt will be listed as: “C:\> <command>”. Commands issued to ADB Shell will be listed as: “# <command>”.
1. Enable USB Debugging on your phone;
2. Get permanent root. I used the app z4root which can be found here on XDA;
3. Install Droid2 Bootstrap. It may be downloaded from Market to support the developer. More info here http://www.koushikdutta.com/2010/08/droid-x-recovery.html;
4. Open Droid2 Bootstrap and click “Bootstrap Recovery”;
5. Use bootstrap to reboot into Clockwork Recovery and backup your phone;
6. Reboot;
7. C:\> adb remount
8. # stop
9. # mkdir /system/etc/rootfs
10. # cp /*.rc /system/etc/rootfs
11. # mkdir /system/etc/init.d
12. # cp /system/bin/sh /system/bin/_sh
13. # cp /init_prep_keypad.sh /system/bin
14. C:\> adb push sh_hijack.sh /system/bin/
15. C:\> adb push 2nd-init /system/bin/
16. C:\> adb push sysinit /system/bin/
17. C:\> adb push sh /system/bin/
18. # chmod 755 /system/bin/sh
19. # chmod 755 /system/bin/sh_hijack.sh
20. # chmod 755 /system/bin/2nd-init
21. # chmod 755 /system/bin/sysinit
22. # ln -s /system/bin/busybox /system/xbin/mount
23. # ln -s /system/bin/busybox /system/xbin/rmdir
24. # ln -s /system/bin/busybox /system/xbin/cp
25. # ln -s /system/bin/busybox /system/xbin/umount
26. # ln -s /system/bin/busybox /system/xbin/run-parts
27. # reboot
28. At this point you should be getting into Clockwork Recovery every time, no matter how many times you have rebooted or if you’ve taken the battery of or not. THIS IS NORMAL. It means that the 2nd-boot + sh hijack is working as it should. The boots into clock recovery are caused by a conflict between sh hijack and logwrapper hijack (used by Droid2 Bootstrap). Continue the guide to fix this issue.
29. In clock recovery menu go to: mounts and storage>mount /system;
30. Open ADB Shell again (it will be available in clockwork recovery as well);
31. # cp /system/bin/logwrapper.bin /system/bin/mylogwrapper
32. C:\> adb pull /system/etc/rootfs/
33. Open init.rc and init.mapphone_umts.rc into a text editor that preserves unix end-line format (e.g.: notepad++). Find all entries of “/system/bin/logwrapper” replacing for “/system/bin/mylogwrapper”.
34. In init.mapphone_umts.rc find entry for “exec /init_prep_keypad.sh” replacing for “exec /system/bin/init_prep_keypad.sh”. Add the following text to the end of this file to be able to run all scripts in /system/etc/init.d at boot time:
Code:
service bootscripts /system/bin/sysinit
class post-zygote_services
disabled
oneshot
35. Save and close.
36. C:\> adb push init.rc /system/etc/rootfs/
37. C:\> adb push init.mapphone_umts.rc /system/etc/rootfs/
38. # chmod 755 /system/etc/rootfs/init.rc
39. # chmod 755 /system/etc/rootfs/init.mapphone_umts.rc
40. Choose “Reboot system now” in clock recovery menu;
You’re all set! Now it is just a matter of changing the rc files in /system/etc/rootfs to customize your system boot.
If you want to log the system boot you may also copy the provided log-init.sh script into /system/etc/rootfs and uncomment the line “exec /log_init.sh” from my init.rc file. Doing so will create the /data/logcat.log file that may get huge in sometime.
2nd-init files and my modified *.rc files attached.
Have fun!

As r2beta0 said for defy porting:
r2beta0 said:
It's very likely, since the 2 devices are very similar. Most of the files I attached are from Milestone1 and works perfectly on MS2. Though I recommend you to NOT replace your *.rc files with the attached ones since they could be not compatible. It would be better if you edit your own files. Also try it ONLY if you have a working version of ClockworkMod Recovery (or other custom recovery). You may adapt this guide for your device and post it here on XDA, just remember to mention my name on credits

Thanks, that looks interesting. I'll look into it later.
Just a big WARNING: if it behaves at it is described on the Defy, DON'T DO THAT, at least not with Tenfar or Kb7sqi 's CWM recovery ports, as booting into Recovery you won't have root adb shell access.

Someone can explain me what is it?

I'm guessing this is the first step to being able to go into clockwork mod recovery from a cold boot.
Sent from my Moto Defy using Tapatalk

So, anyone tried? Or is working in that?

So figured I would give this a shot, and well it doesnt work. Phone just sticks at moto logo.
Yes its true in clockwork you cant get root (#) - so I just pulled the .rc files I needed to edit ahead of time and pushed them to the phone before the first reboot. Thus avoiding needing to boot into clockwork after the described bootloop.
If I get time I will play around with this some more.

What is thisss ??

Samsung sidekick 4G

Has anyone begun working on rooting and customizing roms yet? I know the device isn't out for a week or so but I would figure I would ask. My vibrant I so much better rooted and I wanted the same experience on this sidekick.

Oh really? Cool. So far all I've used is one-click root for the Samsung Epic.... is this similar? I'll check it out, thanks!

Has anyone tried using SuperOneClick yet?? I will probably try in a bit and post back with my results..

Ok... well I didn't try SuperOneClick, but I did root it via the rageagainstthecage exploit...

Want to help me do the exploit on my SK4G to root it man ?
Give me instructions ?!

I got it working on mine too. The basic steps were
1) enable debug USB mode on your phone
2) install Samsung drivers for the phone - right now Samsung's site seems to not have a choice for the Sidekick 4G's model (SGH-T839), but I grabbed the drivers for the Vibrant (at www .samsung.com/us/support/downloads/SGH-T959ZKDTMB) and they worked.
3) get adb shell working on your PC (Google it)
4) download the rageagainstthecage-arm5.bin and Superuser packages from the links in this page: wiki.cyanogenmod.com/index.php?title=HTC_Hero_%28CDMA%29:_Full_Update_Guide (be sure to unzip the files into the directory where your adb.exe program is unless you've put it in your path)
5) reboot your phone and plug it in
6) adb push rageagainstthecage-arm5.bin /data/local/tmp
7) adb shell
8) cd /data/local/tmp
9) chmod 755 rageagainstthecage-arm5.bin
10) ./rageagainstthecage-arm5.bin
11) wait until you get booted back out to your DOS command prompt
12) adb kill-server
13) adb start-server
14) adb shell
15) you should now be at a # prompt. The first few times I tried, I wasn't - I was at $. Doing this from a fresh boot seemed to be the trick. Reboot your phone and try again if you're getting a $.
16) mount -o remount,rw /dev/block/stl9 /system
17) exit
18) adb push su /system/xbin
19) adb shell chmod 4755 /system/xbin/su
20) adb push Superuser.apk /system/app
21) adb shell mount -o remount,ro /dev/block/stl9 /system
22) exit
23) reboot the phone then run an app that requests root, such as Root Explorer, to verify
(p.s. sorry for having to mangle the URL's above, XDA won't let me include links since I haven't posted 8 times yet)

Just to note, on step 16 and 21... it is /dev/block/stl9 rather than st19
Also, after step 20, I had to run the following commands for the superuser application to grant root privledges to applications..
adb shell echo "root::0:0:root:/data/local:/system/bin/sh" > /etc/passwd
adb shell echo "root::0:" > /etc/group

Awesome to see it being rooted so fast.
I'm really interesting in getting this phone but I'm not in the US. Does anyone know if the phone will work outside US?

Dang, good catch, thanks. That's what I get for not copying and pasting from my terminal window...stupid, since I was just chastising two people at work for making the same mistake yesterday. I've edited the original post to prevent problems for people who might start before reading the entire thread.
Interesting about having to create a passwd and group file...I've only run a few root apps so far, but they've worked without me doing this. I wonder if it's app-specific.
Now to start removing some of the damn bloatware this thing comes with!

19) adb shell chmod 4755 /system/xbin/su
i get stuck on there it says unable to chmod no such file or directory . there's SU in my android-sdk/tools

i'm so glad this thing got rooted. i used to be a scene kid with a kick. i dont have this phone, i doubt i'm going to get this phone considering the sensation is droppin soon.... but for nostalgia purposes, i'm glad it got rooted. now you can really hack it!!!
not like the old ones!!

Good looking out...I rooted mine earlier today. What version of Clockworkmod Recovery are you all using?

Double-check your step 18...that's the step that copies the su file from your computer onto the phone. I forget the exact output format, but it shows you a Kb/second number of how fast the file transfer went when it finishes successfully.

I'm not brave enough to try putting the ClockworkMod for one of the Samsung devices on the list onto mine, for fear of bricking it. Don't know enough about that works as far as hardware differences go.
I have removed the APK's listed below from /system/app with no apparent ill-effects. Not that YOU should remove them necessarily - just that they're things I don't have a need for:
AccountAndSync.apk
AmazonMp3.apk
AppPack.apk
DriveSmart.apk
DriveSmartHelper.apk
install_flash_player.apk
LiveWallpapers.apk
LiveWallpapersPicker.apk
Memo.apk
MiniDiary.apk
MobileBackup.apk
MyFiles.apk
PhoneSetupWizard.apk
Twitter-2.0.1-121.apk
vvm-signed.apk
Though there must be something I don't fully understand, because even after a reboot, Amazon MP3 and AppPack are still on my phone, and they still work.
FYI, don't remove Settings.apk - I got stuck in a loop where the launcher kept crashing then reloading itself (thank goodness I was able to put it back in place with adb).
