Remount script ready to go next post down.
Solved ...
The point of this: Save yourself the mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 command ..
The split kernel confused me... It's /sbin in clockwork and /system/bin otherwise...
-- Little buggy on the remount state command not working ... but the remount rw and remount ro do definietly change the state of /system.
Extract the file from the .rar archive.
Get yourself into your clockwork recovery then mount system from the partitions menu and then do as follows from command prompt on the computer...
adb push remount /system/bin
adb shell chmod 775 /system/bin/remount
adb reboot
Should be all set...
Would be awesome to see this in more roms... just handy... that's all...
going to work on a reboot recovery script so that from adb shell we can reboot recovery...

To install from CMD - Terminal
1. Download the fxps script. http://www.mediafire.com/?o525y4b4dewdvor
2. adb shell mount -o rw,remount /dev/block/stl6 /system
3. adb push fxps /system/bin/fxps
4. adb shell busybox chmod 755 /system/bin/fxps
5. adb shell reboot
To Run it
1. adb shell fxps
2 adb shell reboot
To install from Terminal Emulator
"Download the fxps script and move it in your SD Card" http://www.mediafire.com/?o525y4b4dewdvor
$ su
# adb shell mount -o rw,remount /dev/block/stl6 /system (Puts the system in R/W mode)
# cp /sdcard/fxps /system/bin/fxps (Copys the script from SD Card to bin directory)
# chmod 755 /system/bin/fxps (Gives root access to the script)
# reboot
To Run it open the Terminal Emulator and enter
$ su
# fxps (It will start... When it finish reboot)
# reboot
This Script is not mine i just find it and gine it to you in simple way
Thanks the Dev of this Script i hope to see it in Power Menu some day...
Great tutorial but AFAIK all available recoveries have this built in as an option dont they?

Am I the only one who thought that the system-partition should be mounted from /dev/block/mtdblock3 ?
i believe it should be mtdblock3 or you can boot into recovery and just adb shell mount /system
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?
Hey all,
Just wondering what the conversion code for Terminal Emulator would be in order to perform an ADB code, i have tried to convert the code myself below and want to be sure it is ok.
Basic objective is to copy the file gps.conf from /sdcard/code/ to /system/etc/ directly using Terminal Emulator on my Desire HD (Froyo 2.2 firmware 1.32....)
CMD prompt:
adb push psneuter /data/local/tmp
adb push misc_version /data/local/tmp
adb shell chmod 777 /data/local/tmp/psneuter
adb shell chmod 777 /data/local/tmp/misc_version
adb shell /data/local/tmp/psneuter
adb shell
mount -o remount,rw /dev/block/mmcblk0p25 /system
exit
adb push gps.conf /system/etc/gps.conf
adb shell
mount -o remount,ro /dev/block/mmcblk0p25 /system
exit
TEmu:
chdir /sdcard/code
cp psneuter /data/local/tmp
cp misc_version /data/local/tmp
chmod 777 /data/local/tmp/psneuter
chmod 777 /data/local/tmp/misc_version
chdir /data/local/tmp/psneuter
mount -o remount,rw /dev/block/mmcblk0p25 /system
cp /sdcard/code/gps.conf /system/etc/
mount -o remount,ro /dev/block/mmcblk0p25 /system
NOTE: that when i tried cp psneuter /data/local/tmp or even cp psneuter /sdcard it says cp: permission denied
Cheers
if all you want to do is copy the file...then whats the point of all of that??!!
im guessing that your not rooted, since your doing some code from the downgrade thread that gives temp root.
But the whole point of that code is to get temp root for FW greater than 1.32.
Since you want 1.32, use a program called Visionary+ and click temproot is you want temporary root. (Visionary+ only works till 1.32 FW)
And you wont be able to copy to a file to the system partition if your not in root mode.
So in the terminal, type
>su
first thing, then carry on.
If you get a # instead of the $ then your in root mode, if not (or if a message appears) then you dont have permission to go into root mode(or your not rooted).
---and i dont think theres any point of the chdir command.
::::::::::But if you want to use that code, then it'll work if you type 'su' first.
Hey guys,
when i type in adb these commands, it fail at the last.
it says every time: ......is a directory (not copied)
its for my deodexing.
adb shell
su
stop
mount -o rw,remount /system/ /system/
cp /sdcard/done_app/* /system/app/
