I've tried to open anything on the cmd mod, but nothing appears. It just gives me that msg about internal and external. I've tried all the "slashes".

[Bad_Opt_T]

This is what happens when i type this into the cmd

Here're the steps I believe you need to take.

From the SS you posted, your CMD is starting in the following directory: "C:\Users\Thanh\" when your SDK/ADB Shell is located at: "C:\Android\android-sdk-windows\tools" or "C:\Android\android-sdk-windows\platform-tools" depending on whether or not you're running the latest SDK. So when you start up your CMD keep inputing "cd.." until you're at the "C:\" directory. From there input "cd C:\Android\android-sdk-windows\tools" or "cd C:\Android\android-sdk-windows\platform-tools" and you should be good to go with the next steps in the walkthrough.


My recommendation is that you completely understand the guide in full considering a mistake made during the actual flashing may or may not be so easily fixed. I hope that this guides you in the right direction.

I'm new to rooting and I'm having problems with step 4. I'm think I have all the components installed right. Here are some screen shots of were I'm getting stuck.





If I need to post more info please let me know.

ERROR: DEVICE NOT FOUND, Anyone? (After the second adb shell)

[sspletts]

Help!!!

I'm having problems with the first part of step 4 using the Command Prompt.

I open it and go to the file for Android SDK Platform tools. Then I enter

adb push rageagainstthecage-arm5.bin /data/local/tmp/rageagainstthecage

and it come up saying [ device not found ].

I have the LG drivers installed on my pc and the usb cable plug in on

Charge only and USB debugging enabled. I have tried several time with no

luck and at a lose. Can someone help me please!!

Thank you,
Scott


I have gotten past the first part of step 4. Now when I get to the second ADB SHELL it come up again [ Device not Found ]

It is not reconnecting back to adb server. I even waited for 10 minutes and still a no go. Why would this happen? Any Ideas.

Thanks in advance.



Is there anyone out there who can help with this PLEASE????????????

[money5000]

Error:device not found is there anyone out there who has had this error come up for the second adb shell and overcome it? Anyone?

[michael.ahdett]

I'm having the same issue, after running ./rageagainstthecage, and then waiting for upwards of 20 minutes (even though the adb session is terminated after about 30 seconds, and my phone reconnects to my computer nearly immediately), I can't restart adb.

It always says "error: device not found", and the only way I can restart adb is to reboot my phone. When I do that, and then restart adb shell, I still have $ instead of #.

P.S. Using Z4Root, everything works just fine.

[sspletts]

can anyone help please????

[michael.ahdett]

can anyone help please????

Yes: download z4root from , put it on your sd card, and run it with any file manager (I used mini file manager, find it free in the market).

I just got an Optimus T and returned my Optimus S within the 30-day window (CA law). I was frustrated with the uninstallable bloatware on the T and pissed that all my installed apps are at the bottom under 'downloads', forcing me to scroll down every time or put everything on the home screen. Since I had both the S and the T side by side, I decided to root them both and compare since there are some obvious differences in the UI.

The short of it is that I was unable to root the S, which had a current OTA, but I was able to root the T. The behavior of the S was that it did everything as expected when running the rootkit, but I could never get a root prompt (#) or su in as root.

After rooting the T, I installed the free version of Titanium Backup and started messing around. I backed everything up completely (I thought) and did a test uninstalling and re-installing a non-system app. So far so good. I then decided to do the same with some bloatware, specifically the Namco Pacman demo. Unfortunately I didn't look carefully before uninstalling it. Titanium Backup only saves data from system apps, and doesn't save the actual apps. I exchanged emails with Joel (the author of Titanium Backup), who is very helpful and confirmed this.

The phone works fine without the PacMan demo. Do I need to reinstall it in order to ever receive an OTA or if I possibly had to return the phone? If so, is doing this as simple as installing an APK and possibly an ODEX in the /system/app dir? And if so, would someone be willing to help me out? I don't see the demo in the android market.

Next, I upgraded to the Pro version of Titanium Backup and started freezing stuff I thought was unnecessary. I froze the wrong thing because the screen turned black except for the status bar, and when I tried to reboot the phone it hung. I had to reset the phone and start over.

I started looking around at the command prompt in the /system/app dir. Being a noobie but an experienced Unix user, I thought that perhaps the way 'freezing' works is to change permissions on the files in this dir, and 'defrosting' changes the permissions back. If that were the case, I could fix the problem that happened to me by changing permissions back on the right APK at the command prompt.

That's not the way it works. Could someone explain what freezing does, or point me to an explanation of it?

TIA.

I rooted my Optimus T the day after I got it with SuperOneClick (Z4Root is easier to use now) and uninstalled all demo/pay-to-use (TeleNav) apps and received the OTA update a couple of days later with no issues. When I work on the phone I enable RW permissions and restore the RO permissions when I'm done. Rooting or uninstalling games and added programs apparently doesn't affect the OTA update. Perhaps leaving the RW permissions is what causes the problems? Could be deleting a system app that must run for the update.

I also periodically replace the apps in the /system/app folder with the updated ones in the /data/app folder so if I restore my device I don't have to re-download the updates. BE CAREFUL WHAT YOU PUT IN THE /SYSTEM/APP FOLDER, ONE PROGRAM MADE MY PHONE GO CRAZY WHEN INSTALLED IN /SYSTEM/APP, BUT NOT IN /DATA/APP.

P.S. Response to previous post:"all my installed apps are at the bottom under 'downloads', forcing me to scroll down every time or put everything on the home screen" Try Zeam it sorts all programs aphabetically regardless if system or downloaded.

cd /data/local/tmp
./rageagainstthecage (let things sit a couple minutes (2), your phone will disconnect from the computer and you'll be removed from your ADB session)
adb shell This should return a "#" symbol instead of a "$" symbol. If it does you're good. If not go back and start from the beginning of step 4
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
....

I'm stuck from here. When I typed in ./rageagainstthecage , my phone will disconnect from the computer. So how can I get it conencted back? Or did you do anything else? Or just leave it 2mins as you said. Cuz from what happened to my phone, I can't even keep going. CMD just said no devices

[nayquan]

WARNING - This is a cat and mouse game we play with manufacturers. I guarantee you an update will come from LG that patches this exploit and will prevent people from rooting. It will also close your root access if you've already rooted using this method. Long story short, NEVER ACCEPT OTA UPDATES FROM THE CARRIER OR MANUFACTURER.

Notice: There is now an application available called z4root which roots your phone using the same method detailed below. This has been confirmed to work on the Optimus line. Click THIS for more information. I feel the knowledge gained by doing this process yourself rather than a 1-click method will prove to be invaluable down the road if/when you encounter any issues but either way works.

For those who learn visually, iamlilysdad has put together an awesome walkthrough video of this process which you can find

What You'll Need:
- Sun JRE,
- The Android SDK, . Install this on the root of your computer so the path is C:/android
- Drivers for the LG phone installed on your computer. Instructions can be FOUND HERE courtesy of our favorite android hacker, modder, developer, blogger (jack of all trades) gbhil
- And the file I have attached to this post. Download it, unzip it, and put the 3 files inside in your android-sdk-windows\tools folder created from installing the SDK.

/\You need to have installed/done all of the stuff in the "what you'll need" section. From this point on I'll assume you've done that./\

Ready?:
Step 1: Plug your phone into your PC with the USB cable.

Step 2: Make sure the phone is charge only (don't mount as USB drive) and USB debugging is enabled. Menu > Settings > Applications > Development > check mark USB debugging

Step 3: Launch the SDK manager, should be something like C:/Android-sdk-windows SDK Manager

Step 4: Open a CMD window and type the following:
cd c:\wherever-your-sdk-tools-folder-is (mine for example is C:\android\tools however in the new SDK the correct directory would be "Platform Tools", and not just "tools". See what you have on your directory)
adb push rageagainstthecage-arm5.bin /data/local/tmp/rageagainstthecage
adb push su /data/local/tmp/
adb push busybox /data/local/tmp/
adb shell
chmod 4755 /data/local/tmp/rageagainstthecage
chmod 4755 /data/local/tmp/busybox
cd /data/local/tmp
./rageagainstthecage (let things sit a couple minutes (2), your phone will disconnect from the computer and you'll be removed from your ADB session)
adb shell This should return a "#" symbol instead of a "$" symbol. If it does you're good. If not go back and start from the beginning of step 4
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
cd /data/local/tmp
./busybox cp su /system/bin
./busybox cp busybox /system/bin
cd /system/bin
chmod 4755 su
chmod 4755 busybox
busybox --install /system/bin
exit
exit

If you get to this step "busybox --install /system/bin" you get an error, do this:

4-A) Download superuser (free) from chainsDD in the market (this is step 5 below)
4-B) Download titanium backup (free) in the market
4-C) Launch titanium. You should get a request to give it root permissions select always allow. Now in titanium, hit the "problems" button and let it install busybox
4-D) Reboot phone and enjoy

Some phones are having a problem on that step while others are not.

Step 5: Go to the android market on your phone and download "Superuser"(free). The developer will be listed as ChainsDD.

Donations:
What I ask is, if this helps you root, please watch this thread and help someone who may be experiencing issue. Yes, I am asking you to donate your time. The same donation I made while writing this so you could root your phone

Thanks:
gbhil - as always thanks, you rock rainman lol.
- Without your exploit many phones would not be rooted today.
iamlilysdad - for making the walkthrough video and sticking around and providing so much support for new users during this process.

First off Android is a Linux based OS. Your problem with the Command prompt, did you put the 3 files in the SDK platform tool folder? Thats what usually causes that error.

Here is the file that I'm talking about.

Does z4root work lg optimous t ?

[sspletts]

Does z4root work lg optimous t ?

YES

[crowkiller]

So I ran into the 'device not found' error after running ./rageagainstthecage as well.

Further reading in the thread indicates no one has solved this and users have moved on to using z4root.

I think this info should be posted at the beginning of the thread, and save users the frustration. Just my two cents.

[KSmithInNY]

Has anyone tried the idea of, after rageaginstthecage runs, kill the adb server and restarting it to establish a connection with the phone? Haven't seen it mentioned.

P.S. Anyone getting command not recognized is in the wrong directory. Please re-check your installation of sdk on where adb is. If you have the old sdk it's in tools, if you have the new sdk it's platform tools.

I'm more than certain that you might not have an actual answer to this, but it never hurts to ask. Do you believe that the issue that is going on could be due to slight error or timing with the inputing of the commands? I personally didn't have this issue when I went through it prior to switching to the new Rom I'm on. Do you think that there could be some minor mistakes being made during one's progress that could be doing this? Could there be an issue with rig configuration? I know you may or may not be able to answer any given question with certainty, but I figure I'd ask anyways... just in case.

Doubtful but anything is possible. As for timing waiting a few seconds after each step should be enough. Time is more important after rageagainstthecage.

My PC will not let me unzip the OptimusRoot.zip file. I am getting "Error:Access is denied. Cannot create C:\program Files\Android\android-sdk-windows\platform-tools\busybox. Administrative privileges may be required." I do have administrative privileges on my computer. Is there something up with the file? Thanks.

[Bad_Opt_T]

You're exposed to extract the files with the use of an app like WinRAR or 7zip (free). You could also try redownloading the file since the one you have could quite possibly be corrupted.

You are probably right about the bad Optimusroot.zip file. I read somewhere in the post that the file was corrected but I could not access the link. I am getting device not found errors when I try to push the rageagainstthecage-arm5.bin file, so I think it may be a corrupted file. Any ideas where I can get a good copy of the Optimusroot.zip file?

I just tested the file from the first post and it's in fine condition. Try another browser or download manager.
