ADB Remount

Why is it that I can't remount? It keeps saying "remount failed: operation not permitted" ....

use the switch user "su" command first. You can tell you are in the root shell because your prompt starts with a "#" instead of a "$"...then run your remount.
[EDIT] I just realized you were trying to do adb remount instead of in the adb shell. From the sounds of it, you don't have root...then again, I'm still learning Linux. I'd try to mount the system from adb shell and see if that works

I have root used regaws method...

ADB: Permission denied...no matter what i do!!!

OK...I'm beginning to think that rooting is not for me!!!! Getting a bit frustrated!!!
OK, so I installed SDK on my pc (Win XP Ver 2002 SP3), and I cannot get it recognize the device.
I tried the guide for dummies here on XDA, and I follow all the indications, server starts up, I can kill it too....but every time I try to run it I get:
"error: device cannot be found"
The line that I am writing is as follows:
Code:
c:\android-sdk-windows\tools>adb shell
and I get the error above.
When I try to see if devices are connected, and Use this:
Code:
c:\android-sdk-windows\tools>adb devices
I get:
"List of Devices attached", but there is no list!!!!!
But I can see the SDCARD from my computer....I can access the files...
Maybe I can try to pull instead of push, but I'm not sure how that would be written (line wise), not if will work.
BTW...I have never done anything like this on android....very new to this!!!!
umm.. HELP!!!
OK changed pc's,....on this one it does recognize the device, but does not allow me to push anything.....when i try:
Code:
adb push su /sdcard/su
I get adb: permissions denied
------
I tried su +, and that got me to the # prompt. So I tried typing
Code:
# adb push su /sdcard/su
and I get adb: not found???
Running out of options here!
...
Thanks!

I think you are mounting the sdcard. You don't want to do that. Just connect your phone to the computer and run ADB. Don't click "USB Connected. Select to copy files to/from your computer" on your phone.

Funkeeeeeee thank you for the reply.
OK...I am not getting an option when I connect to the pc..on the one I get it, I shose do nothing. I have also disabled mass storage on the device once loaded, adn I get the same error. Here is some of the code that I get thorught the PC's terminal:
C:\>cd android-sdk-windows\tools
C:\android-sdk-windows\tools>adb devices
List of devices attached
HT09YR200737 device
C:\android-sdk-windows\tools>adb shell
$ adb push su /sdcard/su
adb push su /sdcard/su
adb: permission denied
$ adb kill-server
adb kill-server
adb: permission denied
$
Click to expand...
Click to collapse
Notice that once I get the initial permission denied, the terminal seems to get locked up on that no matter what I type....see above...
Anything else to try??? AM I missing something here?

That's fine. There are a few things I can suggest for you to try..
First, I want you to enable USB debugging on your phone by going to Settings > Applications > Development and check that first option.
Then connect the phonoe, but don't use 'adb shell' before pushing files. It should look like this:
Microsoft Windows [Version 6.1.7600]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:\Users\Funkz>cd c:\g2

If you are trying to run it from within adb shell, it will spit back 'adb: not found.' That should do fix it for you.
If it does not, go to Control Panel > System > Advanced > Environment Variables. Then click on Path and Edit, then ";C:\android-sdk-windows\tools\" at the very end and try again.
By the way, you don't have to run adb from the installation directory. After adding the path I just mentioned, you should be able to run it from anywhere.

Thanks.....I finally can run it without having to type the entire path!!!! That was great help!!!
AS for the permission denied.....still having that issue! The one thing I didn't understand was when you changed the path to >g2.....what do you mean???? path to be g2?
Thanks again for the help!
Just a note...I am trying to do this post OTA, which I downloaded, never got the push...Would having the OTA have any effect on this? DO I need to consider reverting to stock and trying from there? If so how? run recovery?
Dude thanks for the help!

did you try typing SU? IMO you cant tamper with ADB Shell if you dont have su access so try typing down SU to ask for permission.

Alright first things first. ADB requires special drivers to work. Which is probably why it didn't work on the original PC. If you download the PDANet client on the PC that you need to do adb it will install the necessary drivers and you can uninstall the program without losing the drivers.
Another ADB requirement is to enable USB Debugging. MENU>Settings>Applications>Development and check the USB Debugging Box.
I don't know about anyone else but with my phone will automount the card. It is recommended to pull down the notification bar and make sure that your SD card isn't mounted.
You need to navigate your command prompt to whatever folder you keep ADB.exe for me
Code:
C:\Users\etnie>cd C:\Users\etnie\Downloads\G2\Android\tools
for me this returns
Code:
C:\Users\etnie\Downloads\G2\Android\tools>
to confirm this
Code:
C:\Users\etnie\Downloads\G2\Android\tools>adb devices
I won't post all the code but it should start the daemon successfully and list your device.
to be able to push files to your phone they also need to be in the same folder as the ADB.exe ie the tools folder. of course you can push it from any folder if you type the full path
Code:
C:\Users\etnie\Downloads\G2\Android\tools>adb push C:\Users\etnie\Downloads\G2\bootanimation.zip /data/local
the above code would push the bootanimation.zip from my G2 folder located in my Downloads folder to /data/local on the phone. changing the boot screen animation when you turn on the phone. I actually have the BIOS one. Because I am huge nerd lol. Moving on...
I think I covered everything necessary....If you are still having problems either PM me or reply here.

Thanks guys for the replays...here are some comments...

Runca thanks for the detailed reply....going in order here:
1 - I did and I still have pdanet isntalled
2 - it's been like that since the first day I got the phone.
3 - How do I ensure??? you are talking about from the phone....I should turn off USB Storage? Will try this one.

4 - It's pretty much what I have. Other that I'm not running su before doing so......
Any thoughts?

The "g2> " bit is just his command prompt. He's changed directory to one called "g2" on his phone but that's nothing to do with how adb works etc (just that if he pushes or pulls files then that'll be the current directory on the PC for that).

Those "adb push" commands should be done from your PC's command prompt, not from within an Android shell prompt on your phone.
"adb shell" starts a command shell on the phone. Which is fine for doing some stuff. But "adb" commands won't work because now you're issuing them to your phone, not your PC.

Thanks Steve.....that makes a lot of sense, and in part why i am a bit lost here....but knowing that....how can I get to "push" things to my phone?

Don't run the adb shell command. That takes you into the phone's prompt. Any commands you run from adb shell with $ or # are run within the phone. You want to run adb push from command prompt. Look at my previous post. It should look like:
C:/>adb push ...
not
#adb push...

Finally progress
Guys thank you for your help!!!!!
I was finally able to push all the files to the phone. Now my problem has changed..., still dealing with Permission denied....when executing rage I get a buch of errors, please see image:
Code:
$ $su
# /data/local/tmp/rage
I get this.....
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I then figured that since I was temp rooted through Visionary r10, that was the reason for the errors above. I then proceeded to reboot without temp-rooting.
When I come up to the terminal I get:
Code:
export PATH=/data/local/bin:$PATH
$ $su
su: permission denied
$
SO if I understand this correctly, I need NOT be temp-rooted in order to run rage, but if I'm not temp-rooted, I don't have permissions to get to execute rage....there a chicken and egg story here somewhere! lol
Can I use a hybrid of the visionary temp root and perm root in that post?

From what I recall you need to uninstall visionary and reboot prior to using the rage method.

Thanks funkeee...I will try in the morning.
But part of the problem is that without visionary I cannot get su access to run any of this. I'll backup VIS r10 before removing, and try again.
I post my results...goodnight and thanks!

I looked at the rage instructions and the prompt is misleading. You may forgetting to use chmod to change permssions. I've put my version of the instructions (just the start).
Uninstall visionary, reboot and from command prompt on your pc, navigate to the folder where you have these files and run:
c:/> adb push su /sdcard/su
c:/> adb push Superuser.apk /sdcard/Superuser.apk
c:/> adb push rage /data/local/tmp/rage
c:/> adb push busybox /data/local/tmp/busybox
c:/> adb push root /data/local/tmp/root
c:/> adb shell chmod 0755 /data/local/tmp/*
Don't forget the last entry, which changes the permissions.
Then on your phone, open terminal and put in:
$ /data/local/tmp/rage
It will say Forked Childs...
Then Menu > Reset Term. It will close, then launch terminal again, it will force close and then launch it again and you will have rage root.
If you get to there, you're in good shape. You can then follow those instructions to to push hboot and wpthis. Be careful with the dd command and be sure you have it exactly right. There are no do-overs with 'dd'.

But is with this part that I have issues with......
I uninstalled VISONary as suggested, and I got the same result as before.....error, error, error.....permission denied! Basically without visionary and su I cannot get access to the run rage. I gave me this error:
Code:
$ /data/local/tmp/rage
/data/local/tmp/rage: /data/local/tmp/busybox: permission denied
mount: Operation not permitted
mkdir failed for /system/xbin, Read-only file system
/data/local/tmp/rage: /data/local/tmp/busybox: permission denied

/data/local/tmp/rage: /data/local/tmp/busybox: not found
cp: Permission denied
cp: Permission denied
Unable to chmod /system/xbin/su: no such file or directory
Mount: Operation not permitted
$
SO as i interpret this as I dont have the rights or permission to run the rage script. What puzzles me is the fact the it cannot "mount" the sdcard...after running this, I cannot take a picture (screenshot) bcs it does not recognize the sdcard. I have to Reboot.
Any ideas?
Thanks!

I think there's something majorly wrong here. Funny, I saw someone else with a similar problem recently. It looks like when you're running "rage" it's actually running the "root" script that you use at a later stage, and not "rage" at all. Double check what you've got, I think "rage" is a binary and not a script. Are you sure you didn't push "root" to "rage" ?

How to root manually/without Windows

There is already an excellent write-up on how to use SuperOneClick to root your Optimus V.
Unfortunately, you may not have a Windows machine available to run the util, or your PC hates the LG drivers, or you may wish to control how you go about rooting your device.
Hence this short write-up which, obviously, relies on pieces I got from that other write-up.
I. Rooting your device
1. You still need ADB!
2. Download the LG Optimus V Tools package from http://nexus.zteo.com/projects/tools/
3. Unzip it
4. Command-line:
Code:
adb push psneuter /data/local/tmp/
adb push su /data/local/tmp/
adb shell
cd /data/local/tmp
chmod 777 psneuter
chmod 777 su
./psneuter
5. You should be kicked out of the shell
6. Command-line:
Code:
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
cat /data/local/tmp/su > /system/bin/su
mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
(Oh look you are root!)
That's it. You now have permanent root access.
After rebooting your phone, adb should be back to logging you in as a regular user but typing "su" will do the trick.
Note: I realize that the version of SuperUser.apk that comes with SuperOneClick might be re-usable here. I haven't had any success with it but you may.
II. Flashing a new ROM
1. After rooting your device, obviously...
2. Get an image for the ROM you wish to flash...
Currently, my favourite one is a fairly recent version of Zefie's CM7.
You can find it by googling "update-cm-7-04282011-NIGHTLY-thunderc-Xionia-signed.zip" -- I will refer to it, below, as <your_rom_zip_file>
3. Get a minimum Google Apps package for flashing as well.
Here, I would google "gapps-gb-20110325-signed.zip" -- I will refer to it, below, as <your_gapps_zip_file>
3. Command-line:
Code:
adb push flash_recovery /data/local/tmp/
adb push recovery.img /sdcard/
adb push Debug-FormatSYSTEM.zip /sdcard/
adb push <your_rom_zip_file> /sdcard/
adb push <your_gapps_zip_file> /sdcard/
adb shell
su
chmod 777 /data/local/tmp/flash_recovery
/data/local/tmp/flash_recovery /sdcard/recovery.img
reboot recovery
4. In recovery: Flash Debug-FormatSYSTEM.zip
5. In recovery: Wipe cache and dalvik-cache
6. In recovery: Flash <your_rom_zip_file> -- this will take a while
7. Do not reboot!
8. In recovery: Flash <your_gapps_zip_file>
9. Now, reboot.
10. Let your phone think about life for a few minutes
11. Select "Skip" when your phone asks you to create/enter your account info
12. Launch the market; now, enter your main account information

Hey first of all let me tell you that I appreciate this guide. Now my problem is that I am such a noob that I may be doing this wrong.I download the file to my optimus.Then in an explorer I extract it, correct? After that once I put in the first line of command on terminal emulator I get an error that says "adb: permission denied". Please help this guide is my last resort.Whatever I do I can not root through windows.It would be nice if you could explain in more detail every step. Thanks!

help
can u please add a little more detail thank u very much appreciated.

SouthParkFan15:
adb is a tool that you run on your computer; it is available for Windows, Mac OS X and Linux. It is part of the Google SDK.
thizizjohnny:
Could you give me a little more detail regarding what detail you are interested in?

How do I unzip?.. is extract the same thing? I'm running Linux mint 10. How do I get adb? Excuse my noobness.
Sent from my VM670 using XDA App

Oh and one last thing.. does this work on android version 2.2.1?
Sent from my VM670 using XDA App

Yes this works with 2.2.1.
On Linux Mint, you can use the package manager or the unzip command in a terminal window.
apk:
Download the SDK at http://developer.android.com/sdk/index.html
Install it, then run "android" and select "Install platform tools"

I finally got adb on my system, but when I type in "adb devices" nothing comes up and when I do any command that involves the phone i get "error:device not found".Yes I have usb debugging on and yes I have all the right drivers installed and yes I have tried rebooting a million times, and no my computer has never recognized my phone the way it should.Let me also point out that though pdanet or droid explorer they can't find my device. Help please I'm desperate!

Oh, my. Sorry to read that.
Problem is, in 2.2.x, the exploits that give you root access rely on ADB itself so you couldn't be more out of luck.
On second thought...this may seem a bit weird but there may be a way. I have to think about it. It would involve using a file manager that agrees to "see" /data/local/tmp, running psneuter from there and keeping our fingers crossed. I'll keep you updated.

Alright thanks cyansmoke! Keep me informed.

I ran all of the steps for rooting and I didn't get one error. It didn't seem to work though. When I launch adb again after rebooting my phone I get permission denied when I try to run su.
Here is the cap from my command line. I have no idea why it didn't take.
C:\phone\LGOptimusVTools>adb shell
$ cd /data/local/tmp
cd /data/local/tmp
$ chmod 777 psneuter

It's possible that you have another su in your path that takes precedence.
Please try typing:
/system/bin/su

Hey, do you know if there is a way to upgrade my device to froyo 2.2.2? It's currently 2.2.1 and whenever I go to update system it says something like "Your system is up to date".Incase you have forgotten I have the optimus v that can't establish connections with the computer.So what I could do?I'm thinking that If I do that then maybe it could fix all of my problems (or some of them).Thanks

I don't think that it will help you no.
OK it's taking longer than I thought because my wife's LGV, after I restored it to stock, decided that it would not allow psneuter anymore.
Thus, I will need you to run these commands for me and let me know how that went:
1. First, copy psneuter to the root of your SD Card.
2. Then, download Terminal Emulator from the market
3. Run Terminal Emulator, type:
Code:
cp /sdcard/psneuter /data/local/tmp/
chmod 777 /data/local/tmp/psneuter
/data/local/tmp/psneuter
Now, if we are lucky, you should get kicked out of the terminal app (I know it's weird but there is a claim that it goes through adb(!))
Restart the terminal emulator. If we are double-lucky, your prompt should have changed from '$' to '#'
Fingers crossed. Still surprised to hear that terminal emulator would go through adb. No, let me rephrase that: I am moderately surprised, in fact, considering the limitations put on non-rooted apps.

After I put psneuter on the root of my sdcard.I go to terminal emulator and put in the first code and it says "cp: permission denied".Any suggestions?

Ah, my bad, no "cp" by default.
New instructions:
Code:
cat /sdcard/psneuter > /data/local/tmp/
chmod 777 /data/local/tmp/psneuter
/data/local/tmp/psneuter

After I put in the first code I get an error message saying "cannot create /data/local/tmp/: is a directory".

*facepalm*
Of course I should have written:
Code:
cat /sdcard/psneuter > /data/local/tmp/psneuter

I put in "cat /sdcard/psneuter > /data/local/tmp/psneuter" and I get an error message saying "cannot create /data/local/tmp/psneuter: directory nonexistent".

Any suggestions?

I then tried to push the same file if i added .txt at the end of psneuter.
This still did not work.
I then typed cd [directory] and tried it (without .txt) and it still did not work.
I then tried it with .txt and it works.
So i had to cd the directory and then add the file extension? Guessing this isn't normal, but i could deal with it.
However when i got to the third line, i don't know the file extension of misc_version, so i was unable to continue. Can anyone shed some light please? What am i doing wrong or what haven't i done?
Thanks

Sounds like you didn't set your path; either set a path to adb or make sure all the files are in the same directory of adb and run the commands from that directory

i thought i did set a path though. and it doesn't explain why i need to add the file extension...or is that normal?
can you remind me how to set a path please? i went to computer and path>edit then added the directory of platform-tools and tools to the list. is that all thats needed? where should i save the files such as psneuter?
thanks

All I do is rip out the needed adb files and put them in a folder on my dekstop. Then you can push the files you need to your device.

Sounds like you added the path correctly; if you did, you should be able to run adb from anywhere. It doesn't matter where the files are on your computer, what matters is that you're running the commands from that folder.
For example, if all the files are in C:\root_files then when you open up a command prompt, you need to type 'cd C:\root_files', hit enter and then run the adb commands from there.

Can you not drag and drop the files into the terminal in Windows like you can on Mac?

thanks for all the comments. will have another go tomorrow.
i made another thread but no one has answered, my desire z is running android 2.2.1. do i need to downgrade to 2.2, then 1.74, then 1.34 to root it, or can i go straight from 2.2.1 to 1.34?
Thanks

The 2.2.1 is android version, not sense version.
You need to downgrade to 1.34 sense version, which is also running 2.2 I think.

i solved the above problem but now have a new problem.
After i typed "adb shell /data/local/tmp/psneuter"
to try and get temporary root, i got this message: /data/local/tmp/psneuter: permission denied
I googled about a bit and tried another command:
C:\Root_Files>adb shell
adb server is out of date. killing...
* daemon started successfully *
$ cd /data/local/tmp
cd /data/local/tmp
$ chmod 0755 psneuter
chmod 0755 psneuter
$ ./psneuter
./psneuter
property service neutered.
killing adbd. (should restart in a second or two)
Then tried adb shell again.
It granted me root access, but i figured i'd try and stick to the tutorial i was on.
so i went back and typed adb shell /data/local/tmp/psneuter again, and now i get this message:
mmap() failed. Operation not permitted
however if i typed "adb shell" i get #.

[Q] Rooting AT&T S3

So I am trying to manually root my S3 without flashing a rom. I am able to get through most of the steps in these instructions up to the point where it requires you to put phone into download mode. I get phone into download mode, but when I connect to the PC, it doesn't see the phone.
This step worked:
To confirm your device is properly detected, in the command prompt, run
Code:
adb devices
Now copy busybox, su, superuser.apk to /data/local/tmp/ using adb.
Code:
adb push busybox /data/local/tmp adb push su /data/local/tmp adb push Superuser.apk /data/local/tmp
These steps worked:
Now run adb shell
Code:
adb shell
Note that you see a "$" sign in the command prompt. That means you are not rooted.
Next run the following commands in the shell to change permissions and get some limited privileges for the Superuser files:
Code:
chmod 6755 /data/local/tmp/su chmod 755 /data/local/tmp/busybox chmod 644 /data/local/tmp/Superuser.apk
Note that the names of the files are case sensitive.
Files are there and are verified when I ls /data/local/tmp. All three files are there.
This is where I have a stumbling block:
Once in download mode, connect the Android device using the microusb cable to the computer.
Now using the open Nautilus window, navigate to /UserData/local/tmp/ folder and verify that you have the files you sent to the device viz. su, busybox and Superuser.apk
So if I am able to push files to the phone, why won't it recognize it when in download mode?
