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
chmod 777 psneuter
$ chmod 777 su
chmod 777 su
$ ./psneuter
./psneuter
property service neutered.
killing adbd. (should restart in a second or two)
C:\phone\LGOptimusVTools>adb shell
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
# cat /data/local/tmp/su > /system/bin/su
cat /data/local/tmp/su > /system/bin/su
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
# exit
exit
C:\phone\LGOptimusVTools>adb shell
$ su
su
su: permission denied
$
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?

This guide was tested on my samsung galaxy [email protected] gt-B5330 and it worked.
WARNING: this can brick your phone, used on your own risk (both eyes wide open).
The idea behing can be ported on any phone that allows you to upload custom firmware (most samsungs with odin).
The idea is that you escalate to superuser by setting suid on /system/bin/toolbox executable.
By duing that you can run most of the unix commands on android as a superuser.
I is enought for you to copy su utility somewhere where there is not a nosuid option on mountpoint. and make it a suided executable then execute su and get the #.
It's all down hill from here.
I cannot verify for every ics rom out there, but it seems that now ics uses ext4 filesystem for the system partition.
I have made a script that inspects a stock rom firmware isolate the permissions for the toolbox executable and add to them SUID,SUIG.
After that it pachs the firmware back and you can flash it to your device and have a easylly rootable device. (I will post the stept to take to get a standard rooted device).
What you need:
a linux/gnu (it will not work with cygwin because we have to mount the ext4 partition).
simg2img utility (you can get it from xda site it is in ext4_utility packet).
su, busybox and superuser.apk binaries for android (you can take them from a rooting package).
heimdal (for linux) xor odin (for windows and if you cannot flash the firmware on your phone form linux).
I've put all untilities that are not standard into the tar.
just unpack and you have the universal-patch.sh to run over an .tar.md5 firware stock rom.
And post-firmwareUpdate.sh to run after you flash in order to make the root a standard android root.
This was not tested on any other phone (was tested only on GT-B5330) and do it on your own risk.
This rooting does not exploit any weakness (or flaw) in kernel or any thing, it just modifies the stock firmware to make it more flexible so it should be forward compatible with any version of android after ics.
I assume this would exclude HTC's since you meed to be s-off to flash a firmware. I would probably verify that and edit the title if necessary. Other than that, this looks like it could be helpful.
Help to understand the procedure
Hi ETTT,
first of all thanks for your job and effort in finding a solution to this issue.. it has been driving me crazy till now.. but thanx to you i see the light :good: I see it but i cannot really understand the procedure.. Could you please write a step by step explanation of what i need to do. (I am not what we could call a genius with linux).
Thanks in advance.

If you are refering to the procedure that the script is doing here is the version of step by step (with-out the script):
http://forum.xda-developers.com/showthread.php?t=1956653
If you want to know the step by step with the script, here (I will not respond to more basic than this, like how to boot ubuntu and stuff.):
mkdir -p /tmp/foo
sudo mkdir /mnt
cd /tmp/foo
tar -xzf universal-patch.tar.gz
export PATH=./:$PATH
{get the firmware here and unzip it, it should have a file with .tar.md5 suffix}
./universal-patch.sh {the name of the firmware including the .tar.md5 suffix}
wait a while. you should have by the way about 10 times the size of the zip as free space.
if all goes well you will have a myfrm.tar.md5 rady for flashing.
flash the firmware, and after boot enable usb debuging, hook the phone to pc
sudo adb devices
./post-firmwareUpdate.sh
you should have a rooted phone.
you cannot go any more basic than that.
Have fun.

I don't know windows that much to make a batch clone of the script. so you need linux.
But you can use a live cd (maybe from ubuntu) to run the script.

Hello,
I'm trying to install TWRP on my LG D722, but I get the following error in adb shell

dd: /sdcard/twrp-jagnm.img: No such file or directory
even tho the path is correct. Through some experimenting I've found that i get the same error just by doing
Code:
[email protected]:/ # cd /sdcard
tmp-mksh: cd: /sdcard: No such file or directory
On the other hand i can do
Code:
[email protected]:/ $ cd sdcard
[email protected]:/sdcard $
which doesn't help me because i need the su permissions.
I would appreciate any help you can provide.

Hi,
I, unfortunately, don't remember how I solved this issue exactly, but I think the problem was something with a broken symlink ( tbh I'm not sure whether it was broken or I was just doing something wrong). I am not able to reproduce the error now so I cant be more specific but try typing
Code:
ls -la
and you might be able to change directory to the target of the symlink.
