If anyone can post a link to a detailed Ubuntu guide for newbies to root the Hero and remove stock apps, I would appreciate it. The guide posted doesn't go into too much detail in Ubuntu since the OP said that he could not get it to work in Ubuntu. Thanks.

Wouldnt the Mac version work since they are both *nix?
I was able to root my Sprint HTC hero just fine running Jaunty. I followed the instructions in the guide you mentioned, for Ubuntu. One thing I noticed is before adb recognized my phone, I had to start "HTC Sync" from the phone's notifications. Just ignore the error about it not finding HTC Sync on your PC. Obviously it never will since HTC Sync is a Windows app
Here's the step by step that worked for me: http://romeosidvicious.com/2009/11/09/rooting-the-htc-hero-with-ubuntu-karmic/
I typed it so I could find it easily if necessary and figured why not share it....
romeosidvicious,
Thanks for all your hard work. I and others really appreciate it.

Great, now my Ubuntu Jaunty machine won't detect the phone. I did the above but it still won't work. Im gonna reboot and retry...
Edit:
Nope, no love for my Ubuntu. It's not seeing the Hero. I will have to research this one.. If anyone has suggestions, please chime in.
Ok, found a solution:
http://forum.xda-developers.com/showthread.php?t=537508
----------------------------------------------------------------
Here is the part that solved it for me:
Setting up UDEV to recognize HTC Device -
1. Type the following into a terminal (Applications > Accessories > Terminal):
Code:
gksudo gedit /etc/udev/rules.d/51-android.rules
2. Now add the following line to the blank file:
Code:
SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"
3. Click save and close.
4. To restart udev, open up a terminal and enter:
Code:
sudo /etc/init.d/udev restart
---------------------------------------------------------------------
Thanks to Wddglr for all the useful info. It looks like I will be using other things he posted about. Hopefully that info will help someone else.
Just curious, which version of Ubuntu are you running? I didn't have to make any UDEV changes in Jaunty.

I want to follow through with this...
I was following this
http://www.youtube.com/watch?v=ArMO5IHS2eI
until the step came to plug it in and then he suggested typing "adb devices" which told me this.
"~/android-sdk-linux/tools$ adb devices
bash: adb: command not found"
So I came here and I want to follow the links tutorial.. two questions
Is it safe to proceed even though i've been told adb: Command not found
will i be able to proceed although ive been told this command is not found?

Try:
sudo ./adb devices
From the same directory. Or, you can specify the full path:
sudo ~/android-sdk-linux/tools/adb devices
To answer your other questions, it won't work if it says the command is not found.
Okay
It worked but I must have turned into an idiot when i decided my operating system was good enough.
This isn't working, and I am not even upgraded to the operating system the tutorial is written for...
194 updates due... running 8.04 with a bunch of double half installed broken applications.. maybe I should reformat.
I'll let you guys know how things go which ever way it goes.

It looks like you copy/pasted this whole section as a block. I think you need to execute the commands one at a time, and wait for a new "#" prompt between each one. The reason the terminal stops responding is that as one long string, it's not a meaningful command.

I didn't, although i did try that as well
after I would do the mount commands i would no longer get a $ or a # sign, it was just a bunch of nothingness...
I ended up booting up my girlfriends vista and then spent quite a while figuring out how to get the driver for adb, I had to follow two different windows guides for rooting for some reason as well... so if that says anything.. just imagine how long it took me to realize how to get the driver hahah

no, I'm having the same problem. After the "mount" command it gives me nothing.
Edit: doing this in karmic
Odd. I've had no problems following the generic procedure from theunlockr on ubuntu. My only suggestion would be to turn
Code:
./adb shell /data/local/asroot2 /system/bin/sh
into
Code:
./adb shell
/data/local/asroot2 /system/bin/sh
I'm not sure why it should make a difference, but on my computer "./adb shell <command>" exits the shell when it finishes. From what you've pasted, it doesn't look like that's happening to you, but that's my only guess right now.
If you run "./adb devices" do you see your serial number?
And out of curiosity, why are you running as root on your computer? (sudo su) Have you tried just starting the adb server as root, and running the rest of the commands normally? Does this work?
Code:
./adb kill-server
sudo ./adb start-server
./adb devices
(additional CHOWN notes added below. If you are getting "chown: unknown user/group system:system" read them!
Ok, we do have a WHOLE other thread that was made a sticky already, but you need to read the WHOLE thing to get all the properly interesting parts. I'll make sure I keep this OP up to date.
The following methods enable side loading and installing of apps onto the captivate, without the need of a program on a computer attached via the SDK. There are multiple methods, and for the most part, these methods that have worked flawlessly for many users here on this forum. We're just collecting them all in one post for speed and clarity.
Methods that assist in loading applications, without modification to the settings (a.k.a still need a computer attached) can be found at the collective wiki, http://samsungcaptivate.wikia.com/wiki/How_to_Sideload
ALL METHODS REQUIRE ROOT & BUSYBOX:
Root your phone, see http://forum.xda-developers.com/showthread.php?t=725555
Busybox : http://www.appbrain.com/app/stericson.busybox
Please, save a clean, un-altered backup copy of this file. To be safe. Rarely does corruption occur, but if it does, it won't be good.
Method 1: From Win7x64, Samsung Drivers, Android SDK installed.
This method uses the tools you already have at hand, as part of the SDK. All instances in code blocks are run inside of the command prompt. You will need to know where you installed your SDK, and the tools directory therein.
Once rooted, go install BusyBox installer from the App Market/AppBrain etc and run it. It will download and install the latest version for you.
From my Win7x64, with USB Debugging ON. Ensure that you phone is UNLOCKED as it the SU app will ask for permission for 'UNKOWN' in the following command.
Connect to PC, and Eject/Safely Remove the SD card, and "Turn off USB Storage" on the phone.
open command prompt, follow along:
Code:
> c:
> cd \android\tools
> adb shell
$ su
# cp /dbdata/databases/com.android.providers.settings/settings.db /sdcard/settings.db
# exit
$ exit
mount the SD cards to the pc,
"USB Connected select to... ", Mount
mine mounted as H:
Code:
> copy H:\settings.db settings.db
> sqlite3 settings.db
~> update secure set value="1" where name="install_non_market_apps";
1 row updated
~> .quit
> copy settings.db H:\settings.db
Eject the drive, safely remove, etc.
"Turn off USB storage" etc, to mount it back to the phone
Code:
> adb shell
$ su
# cp /sdcard/settings.db /dbdata/databases/com.android.providers.settings/settings.db
# chmod 660 /dbdata/databases/com.android.providers.settings/settings.db
# chown system.system /dbdata/databases/com.android.providers.settings/settings.db
# exit
$ exit
> adb reboot
Bam. Done.
Method 2: with Root Explorer
(courtesy of kirbo20)
This is a pretty easy process. I went in to Root Explorer - dbdata - databases - com.android.providers.settings, copied settings.db to my sd card, edited it on my pc with a db editor changed 0 to a 1 next to non market apps. Copied it back to the original directory, rebooted and installed a non market app.
(added by gotfolk)
again using FF plug in..
Click Secure on the left pane
click on install_non_market_apps
click edit
number 3 states value click there and type in 1. hit ok
(/gotfolk)
Please use caution. If you want to make sure the db save properly open it on your sd card before you copy and replace the original. It should open up as a readable table. If it opens up in a txt editor its corrupt. This permanently enables non market apps. You can not toggle it on and off.
( This is a sqlite3 database file, you can find many GUI editors that will be able to handle the editing, including a FF plugin. Search "SQLite" )
Method 3: with Root Explorer & Sqlite Editor & Terminal Emulator
(courtesy of ice3186)
- Open Root Explorer
- Browse to /dbdata/databases/com.android.providers.settings/
- copy settings.db to the root of your sd card ( /sdcard/ )
- Click on the newly copied settings.db in /sdcard/, with SQLite Editor installed, you can open and edit it here.
- Select the "secure" table, and update the value of 'install_nonmarket_apps' from 0 to 1, and save.
- close out of SQLite editor
- copy the modified file ( /sdcard/settings.db ), and browse back to /dbdata/databases/com.android.providers.settings/ and paste
- confirm the overwrite if asked and then open again to confirm it's been changed.
- open Terminal Emulator
Code:
$ su
# chmod 660 /dbdata/databases/com.android.providers.settings/settings.db
# chown system.system /dbdata/databases/com.android.providers.settings/settings.db
# reboot
- reboot phone.
No PC, no Mac, no drivers, no SDK. Viola.
Method 4: Mac & Android SDK
You will see "[sdcard]" through this method...I don't own a Mac so I'm guessing a bit.
This method uses the tools you already have at hand, as part of the SDK. All instances in code blocks are run inside of the Terminal. You will need to know where you installed your SDK, and the tools directory therein.
Once rooted, go install BusyBox installer from the App Market/AppDroid etc and run it. It will download and install the latest version for you.
From a Max OS X, with USB Debugging ON. Ensure that you phone is UNLOCKED as it the SU app will ask for permission for 'UNKOWN' in the following command.
Connect to Mac, and Eject/Safely Remove the SD card, and "Turn off USB Storage" on the phone.
open Terminal, follow along:
Code:
> cd /android/tools
> ./adb shell
$ su
# cp /dbdata/databases/com.android.providers.settings/settings.db /sdcard/settings.db
# exit
$ exit
mount the SD cards to the Mac,
"USB Connected select to... ", Mount
mine mounted as [sdcard]
Code:
> cp [sdcard]/settings.db settings.db
> ./sqlite3 settings.db
~> update secure set value="1" where name="install_non_market_apps";
1 row updated
~> .quit
> cp settings.db [sdcard]/settings.db
Eject the drive, safely remove, etc.
"Turn off USB storage" etc, to mount it back to the phone
Code:
> ./adb shell
$ su
# cp /sdcard/settings.db /dbdata/databases/com.android.providers.settings/settings.db
# chmod 660 /dbdata/databases/com.android.providers.settings/settings.db
# chown system.system /dbdata/databases/com.android.providers.settings/settings.db
# exit
$ exit
> ./adb reboot
Method 5: Android SDK only
Of course, this also requires root and BusyBox.
From the android sdk tools folder in a command prompt:
note: all linux/mac should use './adb' in place of just 'adb', and place quotes on the echo statement between echo and |
Code:
adb shell
su
chmod 666 /dbdata/databases/com.android.providers.settings/settings.db
exit
exit
adb pull /dbdata/databases/com.android.providers.settings/settings.db settings.db
echo update secure set value = 1 where name = 'install_non_market_apps';|sqlite3 settings.db
adb push settings.db /dbdata/databases/com.android.providers.settings/settings.db
adb shell
su
chmod 660 /dbdata/databases/com.android.providers.settings/settings.db
chown system.system /dbdata/databases/com.android.providers.settings/settings.db
reboot
NOTICE
You must chown the settings.db file and reboot once it is back in its original location. If you do not, you will not be able to alter settings such as WiFi,GPS, default Ringtones, etc. It's also highly likely that you may wish to chmod to 660 (-rw-rw---), so I've tacked that in here and above.
Code:
> adb shell
$ su
# chmod 660 /dbdata/databases/com.android.providers.settings/settings.db
# chown system.system /dbdata/databases/com.android.providers.settings/settings.db
# exit
$ exit
> adb reboot
Chown Note
In the event that you are getting "chown: unknown user/group system:system" please try 1000.1000 as this has been reported to work on several of the samfirmware-released roms that fail with this message.
Absolutely do not use someone else's settings.db unless you specifially make it a point replace android_id with your android_id!
Special Note
Any of these adb comments can be run from Terminal Emulator (Android Terminal Emulator, free) from the su command. I use the ADB here as it is a lot easier to type into. Terminal Emulator will provide you with a shell that is an exact match of the 'adb shell' command, as they both simply provide the shell to you.
Result:
After completing this process you will be able to load non-market apps directly from the APK files, SDK tools, tools such as DroidExplorer and apps such as APKtor.
You will be able to download the APKs directly, and then install from your favorite file browser (e.g. MyFiles(s), Astro(f), RootExplorer($)...)

bump.. settings.db people.. please read the threads!!
good stuff!!!
Ok. I can find settings.db with root explorer. i can copy it and i put it in my sdcard folder but nothing is there when i try to find it on my computer. Im trying to use SQlite editor on firefox. Im also on a powermac g4 if that makes a difference. I did download sqlite editor on my phone and I can find where to change the values for installing non market apps but when I change from a zero to a one it denies me. Please help
Ok, so let me make sure I have your process:
- Rooted
- Installed busybox ?
- Installed Root Explorer
- copied settings.db to /sdcard
-- cant see the file when mounted to Mac, thus can't edit with FF plugin
-- SQLite editor for android wont allow access..
(is this the SQLite Editor you used? http://www.appbrain.com/app/com.speedsoftware.sqleditor)
Try installing "Android Terminal Emulator" from the market (http://www.appbrain.com/app/jackpal.androidterm)
- open Terminal Emulator
$ su
# cd /sdcard
# chmod 777 settings.db
# exit
- Open the sqlite editor, and make the change
- back to Terminal Emulator
$ su
# chmod 660 settings.db
- proceed with rest of instructions.

Please read my initial post, first few lines. I explained why, specifically: Consolidation.
Thanks I will give it a try later today.
Sent from my SAMSUNG-SGH-I897 using XDA App
- OP updated to reflect stock ownership settings for 'chown'
Also, which sqlite app are you using? I'll put that up as method 3 if it works out nicely for you.
fixed a typo in the chown command.. bad copy paste.. bad.. doh.
added method 3 courtest of ice3186
added links to Root Explorer ($), SQLite Editor ($) and Android Terminal Emulator (free) and added the chmod/chown commands to method 3, as they were skipped by accident.
bump** for newcomers, sry.
thanks max for adding the third method. this was by far much easier than the first two methods. I have a hard time getting my mac to talk to my phone sometimes and it was good to not have to plug the lil guy in at all. Worked like a charm
myself and ice3186 are glad we could be of help
If I had accidentally deleted the settings.db how should I go about recovering my phone? Now I have the issue that my phone won't boot past the boot animation and I'm notbsure what to do

Did you make any kind of backup before hand?
You may have to use someone else's settings.db and then do a factory reset.
Depending on how much you've done with the phone I'd suggest deciding on doing a the reboot process for rooting, but choosing to clear data. This may rebuild it, I am not sure.
my dbdata directory is empty.. My phone is less then 2 hours old and i have some market apps installed..

Oh, if it's running, then this folder isn't actually empty.
What are you using to browse this folder?
i followed this guide to a T yesterday when i did this. I used option 1, ADB commands on terminal since i'm a mac and it was super easy, did it in about 5 minutes.
this is just my opinion but i think everyone should try playing with the ADB commands, they're actually really useful and educational to know. and if you should brick your phone, just use clockwork recovery to restore it.
that being said, maybe you should add a disclaimer that when done on a mac, the adb commands require a "./" in front (so adb reboot becomes ./adb reboot). cp, chown, and chmod commands don't need it though (or at least i didn't).
This workshop was held in #android-learning on irc.freenode.net by XDA Member Adrynalyne. All credit to him for this guide, I simply am taking it and turning it into a guide. Here we go!
You can find the raw IRC log here
Good evening folks, and welcome to my ADB workshop. This is by no means a full explanation on the subject, but more of a crash course to help folks get up to speed, and get more from their devices. There may be some things you already know here, so please be patient and respect those who do not.
Reference Files
http://adrynalyne.us/files/How to install adb.pdf
http://adrynalyne.us/files/Using ADB.pdf
So, lets just start with the basics.
What is ADB?
ADB stands for the android debugging bridge and is used for testing and debugging purposes by developers.
However, we like to get more out of our devices, and its a great way to fix things.
Knowing adb can mean the difference between a paperweight and a working phone.
So, to start with, we will look at installing ADB.
Generally speaking, the Sun/Oracle JDK is required to run all SDK functions.
ADB is but one tool in the SDK arsenal.
So, we begin by downloading and installing the JDK. This can be found here:
https://cds.sun.com/is-bin/[email protected]_Developer
Choose your OS, download and install. I recommend that 64 bit users use the regular x86/32 bit version as well.
Moving ahead, we download the Windows sdk from here:
http://dl.google.com/android/installer_r08-windows.exe
Due to already installing JDK, you won't be stopped by the install process.
Now, if you notice, I installed it to:
C:\android-sdk-windows
I did this because it makes things easier when setting up path variables.
I encourage everyone to do the same, but obviously it is not required.
So, this SDK is handy, but is only good up to 2.2. We want the latest and greatest! (Well I do)
So, we navigate to:
C:\android-sdk-windows\
and we run SDK Manager.exe
If you notice in your PDF file for installing adb, you will notice that you can update, and I made a choice not to include earlier sdk versions.
I won't go into full detail on that, but depending on the version of SDK you have, 8 or 9, it WILL make a difference in using adb.
By default, for version 8 adb.exe resides in C:\android-sdk-windows\tools
By default, for version 9 adb.exe resides in C:\android-sdk-windows\platform-tools
We will assume version 9 in this guide
Really, the SDK is installed and adb is usable right now, but in my humble opinion, its not enough
I like the ability to use adb in ANY directory on my machine.
To do this, we edit Windows's environment variables.
Specifically, the system path.
To do this, we click on start, or the orb (depending on OS), and right click on Computer, left clicking on properties in the menu.
If its windows XP, I believe it brings you into advanced system properties immediatly. Vista and 7 need a second step.
On the left hand side, as you notice I have highlighted in the pdf, left click advanced system settings.
Under advanced tab, we left click environment variables...
There are two boxes here.
We are concerned with system variables, however.
So we scroll down the list and highlight path and click edit.
Ignoring all the extra stuff in here, make sure you are at the end of the line, and type
Code:
;C:\android-sdk-windows\platform-tools
The semicolon allows us to separate it
from the previous path statement.
Click ok all the way out.
We now have ADB setup globally. We can use cmd.exe (I use powershell) and no matter what directory we are in, adb is recognized.
If it is not, make certain you entered the path into system variables, and made no typos.
If you installed to a different location, you will need to adjust the path accordingly.
This concludes the section on installing the Android SDK to use ADB.
This next section will be on using ADB, so please open that pdf now.
Now, this applies to any OS, not just Windows.
Well, with the exception of the USB drivers.
I will not go too much into that, but if you take a look at the PDF, it goes through installing usb drivers for the sdk, and how to download them.
Fiarly straightforward, in that rspect.
Now, to setup our phones to use with the SDK and ADB, we must change some settings.
First, we go to menu softkey, then settings.
We scroll down to Applications and tap it.
Under Development, we will check Enable USB Debugging. Please note the SGS phones are different in this respect.
The USB cable must be unplugged before enabling or disabling this setting.
Once this is done, we are now ready to play with adb
One quick note: If you get device not found/conencted, please reboot your phone. DJ05 has a quirk in it where ADBD randomly crashes on boot.
A reboot will fix this
ADBD= ADB Daemon
Ok, continuing on.
Lets look at installing applications. This is also known as sideloading.
Unlike installing from the SD card, it does not require unknown sources to be enabled.
The command for this is
Code:
adb install packagename
This assumes that you are working from the directory where the file is located.
This will install the application to /data/app.
It will also show sometimes useful errors if install fails.
That is not something you will see from the Android GUI.
Now, a lot of us have probably deleted files with apps like Root Explorer. While this isn't really a bad thing, it leaves behind databases and data for the application removed.
This is where the 0kb applicaiton entries come from.
If you take that application entry name, you can uninstall the extra data via adb.
First we go to the adb shell which logs into the phone.
Code:
adb shell
If we end up with a $, we will want admin rights, in many cases. This is not one of them, I don't beleive.
To get admin rights, you want to type
Code:
su
Look at your phone if this is the first time, it may prompt you to allow access. Else you will get permission denied.
If you are not rooted, this will not work either.
Ok, now that we are logged in, we will type
Code:
pm uninstall packagename
where packagename is the name of the 0kb listing.
Now this seems like a pain in the a** and I agree.
HOWEVER
There will be a time where Manage applications crashes when you try to uninstall it from the phone. In this case, a factory reset, or this method is the only effective way to fix the problem.
Moving on.
How many of us have removed system applications or renamed them? Did you know that you can simply disable them from the system?
Code:
adb shell
su
pm disable appllicationname
This will disable it, and the system will ignore it.
This can be seen as safer than deleting or renaming things, but your mileage may vary.
On the other hand, you can also re-enable these applications.
Code:
adb shell
su
pm enable applicationname
Please note: Not all applications will properly re-enable. I believe a factory reset or reinstall of said application will fix the issue.
Also, application names are absolutely case sensitive.
*nix based Operating Systems see the letter 'a' and 'A' as two different things.
when you log into adb shell, you are playing by android rules
Ok, a lot of us tweak and mod our phones and turning off the device to get to clockwork recovery, or battery pulls, or multiple button holds to get into Download mode are troublesome and annoying at best.
ADB can help us here.
Here, we do not need to be logged into the shell
If we want to merely reboot the phone:
Code:
adb reboot
If we want to go to recovery (works well with voodoo5)
Code:
adb reboot recovery
If we want to go to Download Mode because we need Odin, heaven forbid:
Code:
adb reboot download
Its instant. No waiting on animations or anything else.
Its also handy if Android has locked up, but yet still works in adb.
I for one hate taking my case off to battery pull.
So now we move on to pushing and pulling files.
Sometimes, I don't feel like mounting my sd card to copy a file over to my phone.
I can use this command to push a file straight to my sd card:
Code:
adb push filename /pathtodirectoryonphone
So for instance, if I have test.txt that I want to send, I would type:
Code:
adb push test.txt /sdcard/
and there it goes.
Ok moving on
Pushing files can be done to any directory, however, some are protected.
For instance, /system is going to give you a permission denied or a read only filesystem error.
To get around this, the easiest thing to do is push the file to your sdcard, then log into the shell:
Code:
adb shell
Code:
su
We will then mount the system as writable
Code:
mount -o rw,remount /dev/block/stl9 /system
Then we can use something like
Code:
cp /sdcard/test.txt /system/app/test.txt
cp stands for copy
and it requires the path of the file and destination path. The name of the file is optional
When you copy it, you can rename it to whatever you like.
For instance, if we wanted to backup a file
Code:
cp /sdcard/test.txt /sdcard/backuptest.txt
Now, lets assume you do not have busybox installed.
You non rooted users will not.
Then you must use a slightly more complicated command called dd
This is used like this:
Code:
dd if=/sdcard/test.txt of=/system/app/test.txt
if is for inputfile
of= output file
Not every user friendly, but probably one of the safer copy commands.
Ok, moving on to pulling files.
Lets say you want to get a file from your phone, to modify, backup, etc.
To do this, we simply use adb in this manner:
Code:
adb pull /pathtofile/filename destinationname
For instance, if I wanted to backup ADW launcher in system/app
I would do this
Code:
adb pull /system/app/ADWLaucnher.apk ADWLauncher.apk
And it will pull the file from the phone and put it in the current directory.
Like above, you can specifcy where it goes.
pushing files to the sdcard, it seems prudent to talk about changing permissions.
sdcards are typically fat32, which destroys permisisons, and Android is heavily permission based.
So if you push an application to your sd card, then try to copy it to /system/app/ bad things are going to happen, or the app may not even show up.
So in that case, we use something called chmod.
This is used in this manner
Code:
adb shell
su
chmod 755 /pathtoapplication/applicationname
Keep in mind
you dont want to do this while its still on your sd card.
an example
Code:
adb shell
su
chmod 755 /system/app/ADWLauncher.apk
755 is good for applications and script files.
Just a couple more topics to cover.
Lets go over deleting files.
This becomes especially handy for removing rogue applications.
To do this, we must be in the adb shell.
Code:
adb shell
su
rm /system/app/ADWLauncher.apk
You may need to remount system as writable with:
Code:
mount -o rw,remount /dev/block/stl9 /system
That applies when using chmod as well.
So what I did above was delete ADW Launcher from system/app
However, what if I wanted to delete the entire contents of a directory?
Same thing as before, except
Code:
adb shell
rm -f /data/dalvik-cache/*.*
I just cleared my dalvik-cache with that command
very quick, very effective.
If you just tried that, please reboot your phone now
Ok....this leaves us with the final topic: logcat
logcat allows us to log what the OS is doing, and possibly delve information for when things are not working
its quite simple Reading it is another.
To use logcat
Code:
adb shell
logcat
To logcat to a certain file do
Code:
adb shell
logcat > /sdcard/logcat.txt
Now we let the log settle down to a reasonable amount of data coming in and not a wall of scrolling, then start the app in question. When it gives an error, we hit ctrl-C and kill the adb shell session.
This should have captured enough data to see the error. Now, I prepared an example. A user came to me on IRC, and Google Maps was force closing. Clearing data didnt fix it, Clearing dalvik-cache, and fix permissions did not fix it. In this case, the user did not know how to use adb So I had him grab an app called alogcat from the market and email me the log. This is also a very valid method.
this file explains what the problem was, and highlights what to look for as an example.

This concludes the guide from Adrynalyne, there will be more workshops such as this one in irc.freenode.net #android-learning.
Thanks to everyone in #samsung-fascinate !
Reserved for possible extension of topic
Great, saves a lot of questions/answers & search
Every new user should read this!!
Thread stuck as valuable reference thread
Just to add, if I may, a little about the permissions...
============================================================
File permissions for Unix... which Android is based, just so those who tinker with the file permissions may know what they are getting into.
============================================================
Use the chmod command to set file permissions.
The chmod command uses a three-digit code as an argument.
The three digits of the chmod code set permissions for these groups in this order:
1.Owner (you)
2.Group (a group of other users that you set up)
3.World (anyone else browsing around on the file system)
Each digit of this code sets permissions for one of these groups as follows. Read is 4. Write is 2. Execute is 1.
The sums of these numbers give combinations of these permissions:
0 = no permissions whatsoever; this person cannot read, write, or execute the file
1 = execute only
2 = write only
3 = write and execute (1+2)
4 = read only
5 = read and execute (4+1)
6 = read and write (4+2)
7 = read and write and execute (4+2+1)
Chmod commands on file apple.txt (use wildcards to include more files)
Command Purpose
chmod 700 apple.txt Only you can read, write to, or execute apple.txt
chmod 777 apple.txt Everybody can read, write to, or execute apple.txt
chmod 744 apple.txt Only you can read, write to, or execute apple.txt Everybody can read apple.txt;
chmod 444 apple.txt You can only read apple.txt, as everyone else.
Detecting File Permissions
You can use the ls command with the -l option to show the file permissions set. For example, for apple.txt, I can do this:
$ ls -l apple.txt
-rwxr--r-- 1 december december 81 Feb 12 12:45 apple.txt
$
The sequence -rwxr--r-- tells the permissions set for the file apple.txt. The first - tells that apple.txt is a file. The next three letters, rwx, show that the owner has read, write, and execute permissions. Then the next three symbols, r--, show that the group permissions are read only. The final three symbols, r--, show that the world permissions are read only.

Thanks for the guide. Helped me pick out the stupid stupid mistakes I was making...so just a problem. I'm able to use fastboot easily but I seem to be unable to use ADB still on my windows 7. It says there are no devices and I'm dang well sure I have USB debugging on. Is it because Windows 7 is missing drivers for the nexus one or something else?
wonderful guide. I would like to add it to the guides thread.
Really awesome work, thumbs up.
But we should also take a guide on installing adb with Ubuntu/Linux, which isn't a very difficult thing...

This is good but I have a problem, when I try to remove an .apk file from /system/app it fails and says 'rm failed, Directory not empty'
I have followed exact instructions many time but never succeeded :s any help!!
(I am runnging these commands in device mod)
when I am in recovery mod I get this prompt ~ # and I am not able to enter su mod. how to get rid of this??
Well when the $ changes to # it means you have SU access

Ok i think you need to do a recursive force delete which should be rf but i am not too sure! could somebody please confirm/ correct this?
Well, I don't think so ^^ As he doesn't want to erase a whole directory, but only a file.
What surprises me the most is the returned message... You're trying to delete an apk, and it says it's a directory :/
Could you please give us the output of this :
Code:
su
mount -o rw,remount /dev/block/stl9 /system
ls -l /system/app/mytouch*
Perhaps you don't even need the su and mount lines, but I'm not sure about that, and that can't harm your system ^^

I know he doesn't want to delete a whole directory, but since the apk isn't compressed perhaps android looks at is as a directory and not a file? i don't know since what was returned suggested that it was a directory i presumed it was a directory! :S

Using the amazing overclock module made by Tiago Sousa http://code.google.com/p/milestone-overclock/ , it is possible to modify the frequency tables on the motoACTV.
I'm not responsible for what you do to your device. This is potentially dangerous.
Extract the attached overclock.ko in some folder of your computer and open a command line in that folder. You need to have adb installed.
Issue the following commands:
Code:
adb remount
adb push overclock.ko /system/lib/modules/
adb shell insmod /system/lib/modules/overclock.ko omap2_clk_init_cpufreq_table_addr=0xc0049150
adb shell 'echo "0 1000000" > /proc/overclock/freq_table'
adb shell 'echo "1 800000" > /proc/overclock/freq_table'
adb shell 'echo "2 600000" > /proc/overclock/freq_table'
adb shell 'echo "3 300000" > /proc/overclock/freq_table'
adb shell 'echo "1 300000000 20" > /proc/overclock/mpu_opps'
adb shell 'echo "2 600000000 30" > /proc/overclock/mpu_opps'
adb shell 'echo "3 800000000 45" > /proc/overclock/mpu_opps'
adb shell 'echo "4 1000000000 45" > /proc/overclock/mpu_opps'
adb shell "echo 1000000 > /proc/overclock/max_rate"
adb shell "echo 45 > /proc/overclock/max_vsel"
This will create 4 frequency steps:
300MHz. This is the minimum we can get with the current kernel.
600Mhz. This is the stock highest speed. Now the voltage is lower.
800Mhz.
1Ghz.
Now, you can use a program like setCPU http://forum.xda-developers.com/showthread.php?t=505419 to set the maximum and minimum speeds.
Enjoy
On this command (after copying and pasting your commands above):
Code:
adb shell 'echo "0 1000000" > /proc/overclock/freq_table'
I get a return of:
Code:
The system cannot find the path specified.
I tried next to re-run:
Code:
adb shell insmod /system/lib/modules/overclock.ko omap2_clk_init_cpufreq_table_addr=0xc0049150
but it failed, because it already exists.
EDIT: I believe they should be like this:
Code:
adb shell "echo '0 1000000' > /proc/overclock/freq_table"
adb shell "echo '1 800000' > /proc/overclock/freq_table"
adb shell "echo '2 600000' > /proc/overclock/freq_table"
adb shell "echo '3 300000' > /proc/overclock/freq_table"
adb shell "echo '1 300000000 20' > /proc/overclock/mpu_opps"
adb shell "echo '2 600000000 30' > /proc/overclock/mpu_opps"
adb shell "echo '3 800000000 45' > /proc/overclock/mpu_opps"
adb shell "echo '4 1000000000 45' > /proc/overclock/mpu_opps"
EDIT 2: That didn't work... the frequencies aren't in setcpu, even after re-detecting speeds.
can you try this command?
Code:
adb shell grep omap2_clk_init_cpufreq_table /proc/kallsyms
It should return a number, and this number is the one that has to be used for the insmod.
I haven't updated my MotoActv in a while and maybe the kernels have changed.
Code:
C:\Users\Owner\Desktop\MiniADB>adb shell grep omap2_clk_init_cpufreq_table /proc
/kallsyms
[B]c0049150[/B] T omap2_clk_init_cpufreq_table
There was no error when running the insmod the first time, it went through successfully, just the next several lines, and then no change at the end, even after a reboot and re-checking the frequencies in SetCPU.
You are right about the commands, for windows, you have to use this:
Code:
adb remount
adb push overclock.ko /system/lib/modules/
adb shell insmod /system/lib/modules/overclock.ko omap2_clk_init_cpufreq_table_addr=0xc0049150
adb shell "echo '0 1000000' > /proc/overclock/freq_table"
adb shell "echo '1 800000' > /proc/overclock/freq_table"
adb shell "echo '2 600000' > /proc/overclock/freq_table"
adb shell "echo '3 300000' > /proc/overclock/freq_table"
adb shell "echo '1 300000000 20' > /proc/overclock/mpu_opps"
adb shell "echo '2 600000000 30' > /proc/overclock/mpu_opps"
adb shell "echo '3 800000000 45' > /proc/overclock/mpu_opps"
adb shell "echo '4 1000000000 45' > /proc/overclock/mpu_opps"
adb shell "echo 1000000 > /proc/overclock/max_rate"
adb shell "echo 45 > /proc/overclock/max_vsel"
Do not reboot! This changes are not save anywhere yet. It's a bit dangerous because the system will not boot if you put wrong values in there. I'm leaving this for later.
Good work, however the changes are not persistent to reboots. I put them in init.goldfish.sh but still not persistent. When doing it from shell, the changes are there in SetCPU, just not after a reboot. Maybe we could script it somewhere else to start at reboot...
Regards...
I added init.d to the /system/etc folder and added my script - still nothing
I added the script in other shells but still nothing...
I heard that SManager will boot scripts at logon, maybe this is the way to go?
There are a few scripts that are launched by init directly. One for the keyboard, one for preinstall, etc.
Try adding the insmod and echo commands to one of those. I'll test this later and post about it.
I amended the one for the keyboard, no dice. I am going to try again though... keep you informed.
init_prep_keyboard.sh keeps reverting back to what it was before amendments. I am sure that I verified its permissions prior to reboot, it just went back to what it was before and deleted the .BAK file too, wierd.
Peace
Working Solution...
I've tested the method above and it works perfectly.
But as mentioned, the script has to be executed upon every reboot.
Working Solution !!!
I've tested this and it works 100%
- Dump boot.img from watch.
- Extract and decompile boot.img
- Create overclock.sh and put it in etc folder from boot.img
- Write entire script in overclock.sh
- Open init.rc from boot.img
- Add exec /system/etc/overclock.sh in init.rc
- Save changes to init.rc
- Repack boot.img
- Push modified boot.img to watch via fastboot
- Restart watch.
Consider adding overclock.ko in system.img
Overclock is now permanent !!! Even after reboot :-D

Can you possibly make a patched boot.img for us?
tansoftware: This is no easy task on a windows box... I will try on Fedora...
a detailed walkthrough would be superb! i.e. How-to? Otherwise GIYF
Peace
EDIT: This ain't easy in linux either...
If you could post your modified Boot.img, that would be killer!
What bash shell did you use upon init.rc? Could you at least share that with us?
dproldan: This thing WIZZes at 1Ghz! If there were just an easier way to make it persistent across reboots... but what a difference.
I posted on the other motoactv thread a very easy way to overclock.
You need android overclock and rom toolbox pro (maybe the free version works I have no idea)
1. Open android overclock select advanced/custom.
2. Scroll to bottom and select apply preset. This gives you four slots 350, 500, 800, 1000.
3. Open rom toolbox pro, performance, cpu control.
4. Slide the bar to desired speed. You can also set profiles in this section to clock down to 350 while the screen is off etc.
I was able to apply at boot etc and haven't lost the overclocking settings. With cf-bench my score went from 1504 to 2370. You can probably apply settings beyond the slots listed above but you will need to increase the voltages in android overclock. I haven't had time to try it. Another microsoft certification exam this week.
Updated Method...

I can't share my boot.img at this time as it is highly experimental and could easily & un-reversibly brick your watch. My boot.img contains a modified bootstrap.bin that flashes upon boot and forces Android to boot from the built-in MMC instead of internal nvram. Extremely buggy at this stage with several crashes but I'm no longer limited by the 256mb ram on the watch. Hopefully after the bugs are ironed out, we can all enjoy full 8/16 gigs of space. This trick was taken from the nook color modified boot code.
As for how to embed the code into your own boot.img, I believe @Prack posted a simpler cleaner method to overclock the watch. If his method does not work as explained, I'll provide a more thorough explanation of my method.

My guess is he's talking about a swapper2 or some other swap file. It helps but it by no means replaces having more ram. I was on a droid 1 for years and the biggest issue with that phone was the ram/internal storage space. I used swap and 2nd sdcard partitions to make up for it. I'm guessing he's doing the same thing with the watch. Would be interesting to see if he gets any actual improvement.
any more news on this?
permanent settings for the overclock
Attached is a modified "loadpreinstalls.sh" file that will load the module and apply the settings at boot.
Be careful with this, it can prevent your device from booting, requiring a full system reinstall to bring it back.
so, download the overclock.ko from the first post, download and extract this loadpreinstalls.sh to the same folder in your computer and issue this commands from a terminal:
adb remount
adb push overclock.ko /system/lib/modules/
adb push loadpreinstalls.sh /system/bin/
adb shell chmod 755 /system/bin/loadpreinstalls.sh
adb reboot
Now you can use SetCPU to choose the speeds you like and make its changes permanent.
This is working fine for me with the current MotoACTV system releases, it could be broken for some older versions.

This sounds like an awesome application - any way to make it easier for the lay (er) people that know just enough to be dangerous?

How about this. I just wrote a simple windows install script and included all of dproldan's needed files, so all you have to do is unzip this to your desktop and run "runme.bat".
Pre-requesites:
-ACTV must be rooted
-ACTV must be plugged into computer and turned on normally
Called it "dproldan_overclock".
Even included the ADB drivers.
HOW TO ROOT YOUR LENOVO IDEATAB A1000
<DISCLAIMER>
By attempting these steps, your warranty will be void. Even worse than that, it might cause crashes, freezes, random explosions, 2nd degree burns, or even turn your beloved tab into $100+ paperweight. What works on mine might not work on yours, so don't attempt if you don't know what you're doing. Do at your own risk. Corrections are welcome. I must admit that I'm not an expert, so any info I posted might be wrong, and I can't offer you much help. I'm not responsible for anything arising from the use of this how-to. I can only wish you good luck.
<WHY ROOT?>
- Without root or OTA upgrades (at time of writing, Indonesian customers still can't get it), you'll be stuck with ~500MB internal memory. That's annoying.
- You're stuck with the default IO scheduler (cfq) and governor (hybrid, haven't heard that one..)
- You have an incredibly large amount of bloatware you can't get rid of, in that already cramped up internal storage
- Did I mention freedom?
<REQUIREMENTS>
This method is originally used to root Acer Iconia B1-A71. Somehow I noticed that the two actually has the same chipset, MTK8317 (if it really was relevant ). So I tried the method, and through sheer n00b's luck, it worked like a charm!
Lenovo IdeaPad A1000-G --> 4GB storage, 2G/EDGE. This method haven't been tested on A1000-T/F, different storage cap (16GB, etc.) or other variants, but it should work with slight modification. Screenshots of my specs are attached below. Remember, proceed at your own risk!

All awesome gurus on XDA which I can't mention one by one.
<THE STEPS>
1. Extract the android sdk to your home folder, e.g. a user named Bob will use like /home/bob
2. Open a terminal
3. Now plug your A1000 into your machine and turn on Debugging Mode (Go into Settings -> Developer Tools, turn on Developer tools, then turn on USB Debugging Mode)
4. Now back at the keyboard of your Linux machine in your terminal type:
Code:
sudo adb devices
The output should be something like:
Code:
123456789ABCDEF device
If it's not, google for it. Somehow your Linux hasn't detected the A1000, although the android sdk for Linux brings all needed drivers with it.
If your device was found, congratulations. The adb connection between your linux machine and your tablet is intact.
5. Now extract the downloaded busybox archive to your home folder, in it there should be a busybox binary. So Bob does:
Code:
sudo ./adb push /home/bob/busybox /data/local/tmp
Code:
sudo ./adb shell
Code:
chmod 755 /data/local/tmp/busybox
6. You should copy the busybox binary into a directory where you can access it as a plain non-root user on the tablet. We need this binary. so we can apply unix tools like telnet, dd, cat, etc. But for now we need it to establish a telnet session between our tablet and our linux machine.
(This point is written on original post. Seems important, but as soon as I finished step 5, I can use those tools)
7. Dial *#*#3646633#*#* to enter Engineer Mode
8. Go to Connectivity -> CDS Information -> Network Utility
9. type the following command:
Code:
/data/local/tmp/busybox telnetd -l /system/bin/sh -p 1234
Advice from original poster: copy and paste it from the browser on your tablet, because dependent on which keyboard app installed, this can be freakin tricky. In the next step you will learn, why it's so important why this command should be correct.
10. Tap on Run. You won't get any feedback, so you will never know if the entered command runs properly or not. That's why you should make sure the command is ok.
Now we have started our telnet server on the tablet.
11. Back in the terminal type:
Code:
/data/local/tmp/busybox telnet 127.0.0.1 1234
If you now get an error like couldn't find busybox or something, then either adb push failed or you forgot to chmod, in step 5
12. Now enter:
Code:
cat /proc/dumchar_info
You should get a bunch of lines, try to find a line containing the partition named android
{..... partition list .....}
android 0x0000000028A00000 0x00000000020E8000 2 /dev/block/mmcblk0p3
{..... partition list .....}
13. We will create a dump of our android system. This is the point where different variants *MIGHT* have different parameters. This step is important, as wrong parameter will result in unmountable image.
Stop. Take a deep breath. If you're not familiar with dd, find a good doc of it. There's a plethora of them.
Get yourself a programmer's calculator (Linux Mint 15 has one built in).
Here's what you'll do :
Convert the hex number on the 3rd column into decimal. In my case (0x20E8000) will yield 34504704. Divide by 4096. The result (8424) goes to the skip parameter.
Convert the hex number on the 2nd column. In my case (0x28A00000) will yield 681574400. Divide by 4096. The result (166400) goes to the count parameter.
So the full dd command will look like :
Code:
dd if=/dev/block/mmcblk0 bs=4096 skip=8424 count=166400 | gzip > /cache/system.img.gz
Do a full sanity check before hitting enter! It will take about 5 minutes.
14. After it's finished we must make the image readable for adb, so we do:
Code:
chmod 777 /cache
and
Code:
chmod 777 /cache/system.img.gz
15. Leave the telnet, and then adb shell session by:
Code:
exit
Code:
exit
16. Now we pull our image by
Code:
sudo adb pull /cache/system.img.gz
wait 1-2 minutes.
It should be then located inside /home/bob. It did for me. If not, do a search . It should be a .gz, extract it right there (or /home/bob if it isn't there)
17. Now we need to modify our system image by adding the tiny but helpful su binary. Extract the SU binary to /home/bob.
18. We create a folder where we will mount our system image to. To create it do:
Code:
sudo mkdir /media/a1000
19. Now we mount it:
Code:
sudo mount -o loop /home/bob/system.img /media/a1000
if it fails, then you entered wrong parameters on step 13
20. Now we copy our SU binary to our mounted system image:
Code:
sudo cp /home/bob/su /media/a1000/bin
21. the su binary needs to have the proper rights to make it usable, so we 'suid' it with:
Code:
sudo chmod 06755 /media/a1000/bin/su
22. Let's unmount our baby by:
Code:
sudo umount /media/a1000
and because bob doesn't like a messed up system, he does:
Code:
sudo rm -rf /media/a1000
because he hopefully won't need it anymore.
23. We have to gzip it again to bring it back to where it belongs to. this we do by:
Code:
cd /home/bob
Code:
gzip /home/bob/system.img
24. So here we are now, we made it to the final Boss fight! The next steps are dangerous and should be performed with caution. We copy back our modified system image, which can brick your device, if you do a mistake! Enter adb shell again :
Code:
sudo adb shell
25. Remove the old boring image:
Code:
rm /cache/system.img.gz
26. Leave adb shell
Code:
exit
27. copy our cool new system image containing the su binary:
Code:
sudo adb push /home/bob/system.img.gz /cache
28. Enter adb shell again
Code:
sudo adb shell
29. Usually the telnet server on the tablet is still running, at least in my case it's been like that. That's why we can directly connect to the telnet server with:
Code:
/data/local/tmp/busybox telnet 127.0.0.1 1234
If this doesn't work, then obviously your telnet server isn't running anymore. So on your tablet if the telnet command is still entered (see step 9), tap on Run again and repeat step 29.
30. Now this is the most dangerous step in this how to (no it wasn't the mkdir one). You can copy following command to make sure everything is fine and paste it into your telnet session on your linux terminal.
<WARNING! SANITY CHECK! MAKE SURE *ALL* THE DD PARAMETERS MATCH THE FIRST DD (STEP 13) OR YOUR A1000 WILL TURN INTO A VERY EXPENSIVE PAPERWEIGHT!>
Code:
[B]/data/local/tmp/busybox zcat /cache/system.img.gz | dd of=/dev/block/mmcblk0 bs=4096 seek=8424 count=166400[/B]
After 1-2 minutes you're done, if your tablet or pc or yourself didn't catch fire, everything's fine.
31. Leave telnet / adb shell by doing
Code:
exit
Code:
exit
32. Reboot your A1000 via ADB, then exit
Code:
sudo adb reboot
Code:
exit
33. Unplug your tablet from PC
34. Install Superuser (No, not SuperSU, cause it won't work!). I personally use Superuser by ChainsDD, from Play Store
35. Be lucky. Your tablet and thus you are now free!
Don't forget to hit thanks, if this helps
hi, after step 13 (i double checked the command), i get this error
Code:
/system/bin/sh: can't create /cache/system.img.gz: Permission denied
/dev/block/mmcblk0: cannot open for read: Permission denied
I have the WiFi 4G version
Im too stuck in step 13.....nothing wrong with the script, can u give me a solution?
Im using A1000G also
@ts
Your guide work perfectl, in windows enviroment but mount step still need linux,
I've question are you using DirectoryBinding? Mine always close when playing Real Racing, its very annoying
You have suggeztion or alternative for DirectoryBinding?
Root with Windows ?
Hi,
I am a new member because i bought this tblet but i can't root. I don't have a linux environment, so there is a solution with W8 Pro 64 ?
Thanks a lot for you help,

have you chmod-ed the busybox (or is the chmod successful without error)? Try chmod-ing the /cache before attempting step 13. It seems that you still don't have access to the NAND device (mmcblk0). Have you updated firmware via OTA?

Do you encounter the same error message like ulisez had? Could you post the screenshot of the partition list (the lines after you execute dumchar_info)?

I personally use Link2SD by Bulent Akpinar to link apps to 2nd partition on my SDcard.

The original developer who posted the method (entonjackson) plans to integrate the method in the next release his toolkit, the Acer Iconia Toolkit. I think you should check his thread : http://forum.xda-developers.com/showthread.php?t=2240029

I'm not sure whether the stock kernel of our devices supports init.d, thus supports CronMod/Data2SD. Lenovo locked our bootloader, and currently there's no way around it. So I personally think, Link2SD method are the best option for now.
Let's give it several months until our dev gurus bring their miracles upon this device
The attached image shows mt6577 Hardware, can u provide the Soc details please
Hi, Can any one upload Lenovo ideatab A1000 system.img
in step 20, it appears you are writing to a /bin directory on the android system. However such a directory is not visible either through shell or the system telnet account.
Do I need to understand something else about android to make sense of this.

one month gone past but the op seems to be in caves or has bricked the device
STOCK ROM
CAN ANY BODY PROVIDE ME A STOCK ROM OF THIS DEVISE

sorry to make you wait. I'm a last grader university student, and final project stuffs have got me pinned down. Hope you understand
Actually the SoC is MT8317. For some god-knows reason Mediatek have made this SoC with signatures similar to MT6577. But somehow CPU tweaker correctly detects the SoC (MT8317). Maybe it's the CPU-Z bug?

I think you got it wrong. The write process does not take place on the device. It's on the loop-mounted .img in /mnt/a1000 on your computer (step 18-19). Cheers!

Don't worry, the above link is a stock Lenovo A1000 G ROM, but with pre-root files having no superuser app. Just extract the .7z file
